Please help me by showing work . Thank you!

Answers

Answer 1

The most appropriate formula to use in this situation (patient with a bacterial infection and prescribed with Amoxicillin) is Clark's rule, and the dose to administer every 12 hours would be 108.4 mg.

The best formula to use in this situation is the Clark's rule, which is used to calculate the dose of medication for a child based on their weight and the adult dose. The formula is as follows:

Child dose = (Weight of child in pounds / 150) x Adult dose

In this case, the weight of the child is 21.1 pounds and the adult dose is 771 mg every 12 hours. Plugging these values into the formula, we get:

Child dose = (21.1 / 150) x 771Child dose = 0.1406666666666667 x 771Child dose = 108.384 mg every 12 hours

Rounding to the nearest tenth of a milligram, the child dose would be 108.4 mg and to administer every 12 hours.

Scarlett bought a pair of shoes online for $49. She used a coupon code to get a 10%
discount. The website also applied a 10% processing fee to the price after the
discount. How much did Scarlett pay, in the end? Round to the nearest cent.

Answers

Answer:

Scarlett paid $48.51

Step-by-step explanation:

The initial price of the shoes was $49. After using a 10% discount coupon, the price is reduced by $4.90 ($49 x 0.1). Therefore, the price after the discount is $44.10 ($49 - $4.90).


Then, a 10% processing fee is applied to this discounted price. This fee amounts to $4.41 ($44.10 x 0.1).


So the final amount Scarlett paid is the sum of the discounted price and the processing fee:

$44.10 + $4.41 = $48.51


Therefore, Scarlett paid $48.51 for the shoes in the end.

If -3x + 4 <7, then x>-1.
how do you write the indirect proof

Answers

you assume the opposite of what you want to prove, and then show that this assumption leads to a contradiction or an absurdity. In this case, we want to prove that "if -3x + 4 < 7, then x > -1" indirectly.

Assume the opposite of what we want to prove, which is "if -3x + 4 < 7, then x ≤ -1".

Adding 3x to both sides of the inequality, we get:

4 < 3x + 7

Subtracting 7 from both sides, we get:

-3 < 3x

Dividing both sides by 3, we get:

-1 < x

This contradicts our assumption that x ≤ -1. Therefore, our assumption is false, and the original statement "if -3x + 4 < 7, then x > -1" is true. This completes the indirect proof.

Exact surface area. Radius 1 3/4 and height 3 1/4

Answers

Answer:

Surface Area = 10π

Step by step solved:

To find the exact surface area of a cylinder with a radius of 1 3/4 and height of 3 1/4, we can use the formula:

Surface Area = 2πr^2 + 2πrh

where r is the radius and h is the height.

Substituting the given values, we get:

Surface Area = 2π(1 3/4)^2 + 2π(1 3/4)(3 1/4)

First, let's simplify the terms inside the parentheses:

1 3/4 = 7/4

3 1/4 = 13/4

Now we can substitute:

Surface Area = 2π(7/4)^2 + 2π(7/4)(13/4)

Simplifying the terms inside the parentheses:

(7/4)^2 = 49/16

(7/4)(13/4) = 91/16

Substituting these values:

Surface Area = 2π(49/16) + 2π(91/16)

Simplifying the terms inside the parentheses:

(49/16)π = (7/4)π

(91/16)π = (13/4)π

Substituting these values:

Surface Area = 2(7/4)π + 2(13/4)π

Simplifying:

Surface Area = 14/4 π + 26/4 π

Surface Area = 40/4 π

Surface Area = 10π

Therefore, the exact surface area of the cylinder is 10π square units.

Triangle JKL is dilated by a scale factor of
2
2 to form triangle J'K'L'. What is the measure of side L'J'?

Answers

Step-by-step explanation:

If triangle JKL is dilated by a scale factor of 2, this means that all sides of triangle JKL are multiplied by 2 to form triangle J'K'L'.

Therefore, if the measure of side LJ is x, then the measure of side LJ' is 2x. Similarly, if the measure of side LK is y, then the measure of side L'K' is 2y.

To find the measure of side L'J', we can use the fact that the sum of the measures of the angles in any triangle is always 180 degrees.

In triangle JKL, the sum of the measures of angles J, K, and L is 180 degrees. This means that angle JKL is:

angle JKL = 180 - angle J - angle K

Since triangle JKL is dilated by a scale factor of 2, the corresponding angles in triangle J'K'L' are congruent to the angles in triangle JKL. Therefore, angle J'K'L' is also:

angle J'K'L' = 180 - angle J - angle K

Since angle J'K'L' is a straight line (180 degrees), we can find angle J'L'K' by subtracting angles J'K'L' and J'KL':

angle J'L'K' = angle J'KL' - angle J'K'L' = angle JKL - angle J'K'L'

Using the fact that corresponding angles in similar triangles are congruent, we have:

angle J'KL' = angle JKL

angle L'K'J' = angle LKJ

Therefore, angle J'L'K' is:

angle J'L'K' = angle JKL - angle J'K'L' = angle JKL - angle LKJ

Since triangle JKL is a triangle, we know that angle JKL + angle LKJ + angle LJK = 180 degrees. Therefore, we can rewrite the equation for angle J'L'K' as:

angle J'L'K' = (angle JKL + angle LKJ + angle LJK) - 2(angle JKL + angle LKJ)

Simplifying this equation, we get:

angle J'L'K' = angle LJK - angle JKL

Using the fact that corresponding angles in similar triangles are congruent, we have:

angle L'J'K' = angle LJK

angle J'L'K' = angle JKL

Therefore, triangle J'L'K' is similar to triangle JKL, and we can write the ratio of corresponding side lengths as:

L'J' / LJ = K'L' / KL

Since triangle JKL is dilated by a scale factor of 2, we have:

K'L' = 2LK

L'J' / LJ = 2L'K' / LK

Substituting L'K' = 2LK, we get:

L'J' / LJ = 4

Therefore, the measure of side L'J' is four times the measure of side LJ. If the measure of side LJ is x, then the measure of side L'J' is 4x.

Final answer:

The measure of side L'J' in the dilated triangle J'K'L' can be found by multiplying the length of the corresponding side in the original triangle by the scale factor of 2.

Explanation:

In the field of Mathematics, specifically geometry, a dilation is a transformation that alters the size of a figure without changing its shape. If Triangle JKL is dilated by a scale factor of 2 to form Triangle J'K'L', every dimension of Triangle JKL is multiplied by this scale factor to get the corresponding dimension in Triangle J'K'L'.

Therefore, if you want to determine the measure of side L'J' in the new triangle, we need to know the length of the corresponding side in the original triangle (which is LJ). You would then multiply this length by the scale factor. The result would give you the length of side L'J'.

For example, if the length of side LJ in the original triangle is 4 units, the length of the corresponding side L'J' in the dilated triangle would be 4 * 2 = 8 units.

Tanner is spray painting an arrow on the side of a building to point to the entrance of his store. The can of gold spray paint he wants to use covers up to 12 square feet. Does Tanner have enough spray paint for his arrow?

Answers

Using the area formula, it is obtained that Tanner has enough spray paint to cover the arrow with one can of spray paint.

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

To determine if Tanner has enough spray paint for his arrow, we need to find the total area of the arrow and compare it to the coverage of one can of spray paint.

The arrow consists of a rectangle and a triangle.

The rectangle has a length of 2 feet and a width of 5 1/3 feet, so its area is -

Area of rectangle = length × width

= 2 ft × 5 1/3 ft

= 10 2/3 sq. ft.

The triangle has a base of 3 feet and a height of the difference between the width of the rectangle (5 1/3 feet) and the width of the arrow (6 feet):

Height of triangle = 6 ft - 5 1/3 ft = 2/3 ft

Area of triangle = 1/2 x base x height = 1/2 x 3 ft x 2/3 ft = 1 sq. ft.

The total area of the arrow is the sum of the area of the rectangle and the area of the triangle -

Total area of arrow = Area of rectangle + Area of triangle

Total area of arrow = 10 2/3 sq. ft. + 1 sq. ft.

Total area of arrow = 32/3 sq. ft. + 1 sq. ft.

Total area of arrow = 11 2/3 sq. ft.

Therefore, since one can of spray paint covers up to 12 square feet, Tanner has enough spray paint to cover the arrow with one can of spray paint.

Answers

The Aerobics instructor teaches 7 classes each Saturday.

what is Algebraic expression?

An Algebraic expression is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that can be simplified and evaluated.

To find the number of classes the Aerobics instructor teaches on Saturdays, we need to divide the total hours she teaches by the length of each class:

Total hours taught = 5 1/4 hours

Length of each class = 3/4 hour

Number of classes = (Total hours taught) / (Length of each class)

Number of classes = (5 1/4) / (3/4)

We need to convert the mixed number to an improper fraction first:

5 1/4 = (4 x 5 + 1) / 4 = 21/4

Now we can substitute the values:

Number of classes = (21/4) / (3/4)

fractions mean multiplying the first fraction by the reciprocal of the second fraction:

Number of classes = (21/4) * (4/3)

The 4 in the numerator and denominator cancel out, leaving us with:

Number of classes = 21/3

Dividing 21 by 3, we get:

Number of classes = 7

Therefore, To find the number of classes the Aerobics instructor teaches on Saturdays, we need to divide the total hours she teaches by the length of each class:

So, with one acute angle measuring 23.58 degrees and another acute Pythagorean theorem angle measuring 66.42 degrees, we may define this triangle as a right triangle.

what is Pythagorean theorem?

The fundamental Euclidean geometry relationship between the three sides of a right triangle is the Pythagorean Theorem, sometimes referred to as the Pythagorean Theorem. This rule states that the areas of squares with the other two sides added together equal the area of the square with the hypotenuse side. According to the Pythagorean Theorem, the square that spans the hypotenuse (the side that is opposite the right angle) of a right triangle equals the sum of the squares that span its sides. It may also be expressed using the standard algebraic notation, a2 + b2 = c2.  

A triangle with the vertices A, B, and C with sides measuring 5, 12, and 13 units is seen in the illustration.

Let's use our triangle to illustrate this theorem:

[tex]a = 5, b = 12, c = 13\\a^2 + b^2 = 25 + 144 = 169\sc \\a^2 = 13^2 = 169\\[/tex]

Our triangle complies with the Pythagorean theorem because a2 + b2 = c2. Triangle ABC is a right triangle as a result, and the side with the length 13 is opposite the right angle.

[tex]A = arcsin(5/13)[/tex] = 23.58 degrees when sin(A)

= opposite/hypotenuse

= 5/13 A.

[tex]arccos(12/13) = 66.42 degrees B = cos(A) = adjacent/hypotenuse = 12/13[/tex]

A, B, and C are all at 90 degrees.

So, with one acute angle measuring 23.58 degrees and another acute angle measuring 66.42 degrees, we may define this triangle as a right triangle.

Describe coordinate plane.

A coordinate system is a technique used to precisely find points or additional mathematical objects on a distance, such as Euclidean space, by using one or so more values or coordinates. To find a point or item on a double plane, one uses coordinates, which are pairs of numbers. Two numbers called the y and x matrices are used to describe a point's location on a two-dimensional plane. a set of numbers used to identify specific locations.

Here,

The x-coordinate remains constant and the y-coordinate is cancelled when a point on the coordinate plane is reflected over the x-axis (i.e. multiplied by -1). The y-coordinate remains constant and the x-coordinate is cancelled when a point is reflected over the y-axis.

Let's mirror the point (-2, 3) first over the x-axis and then over the y-axis as an illustration:

The x-coordinate remains constant while the y-coordinate is cancelled when reflecting over the x-axis. In light of this, the argument is (-2, -3).

The x-coordinate is cancelled while the y-coordinate remains constant when reflecting over the y-axis. In light of this, the argument is (2, -3).

percent = 88/220 × 100%

percent = 40%

Answer:

40%

Step-by-step explanation:

Our total amount of shoes to sell is 220, right? So we have to find which percentage 88 is of 220! To do this, we use division!

Instead of how you might think to do it, 220/88, we have to do the opposite!
88/220 = 0.4

0.4 is 40% of 1. Therefore 88 is 40% of 220.

What is mean by Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The value is,

⇒ a₁ = - 4

And, [tex]a_{n} = - 3a_{n - 1}[/tex]

Now, We can put n = 2;

⇒ a₂ = - 3 a₁

⇒ a₂ = - 3 x - 4

⇒ a₂ = 12

Put n = 3;

⇒ a₃ = - 3 a₂

⇒ a₃ = - 3 x 12

⇒ a₃ = - 36

Put n = 4;

⇒ a₄ = - 3 a₃

⇒ a₄ = - 3 x - 36

⇒ a₄ = 108

Thus, The value of a₄ is,

What is geometric sequence?

In mathematics, geometric sequence, also known as a a geometric progression, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

Given,

a₁ = 4 and aₙ = -3aₙ₋₁

a₂ = -3a₂₋₁

a₂ = -3a₁

a₂ = -3(4)

a₂ = -12

a₃ =  -3(-12)

a₃ = 36

a₄ = -3a₄₋₁

a₄ = -3a₃

a₄ = -3(36)

a₄ = -108

Hence, -108 is value of a₄ of the sequence.

The value of the missing sides using Pythagorean theorem are;

1.  15. 81m

2. 24. 08cm

3. 12. 85 ft

4. 4. 58 in

5. 27. 02 yd

6.  18. 14 mm

8. 6. 24m

9. 9. 85 miles

10. 14.14 feet

11. 14.14 feet

12. 13. 78  feet

How to determine the value of the sides

Using the Pythagorean theorem, which states that the square of the longest side of a triangle which is the hypotenuse leg is the sum of the squares of the other two sides of the triangle, that is, the opposite and adjacent.

Then, we have;

x² = y² + z²

Where the parameters are;

x is the hypotenuse sidey is the opposite sidez is the adjacent side

From the figures shown, we have that;

1. Adjacent side = 8m

Opposite side = 9m

Using the Pythagorean theorem, we have;

x² = 13² + 9²

Find the squares and substitute

x² = 169 + 81

x² = 250

find the square root

x =√250 = 15. 81m

2. For the triangle, we have;

x² = 16² + 18²

x² = 256 + 324

x = √580 = 24. 08cm

3. For the third triangle:

y² = 19² - 14²

y² = 361 -196

y = √165 = 12. 85 ft

4. For the fourth triangle

z² = 11² - 10²

z² = 121 - 100

z = √21 = 4. 58 in

5. x² = 21² + 17²

x² = 441 + 289

x = 27. 02 yd

6. z² = 27² - 20²

z² = 729 - 400

z = √329 = 18. 14 mm

7. z² = 30² - 25²

Find the squares

z² = 900 - 625

z² = 275

z = √275 = 16. 58 km

8. y² = 8² - 5²

find the squares

y² = 64 - 25

y = √39 = 6. 24m

9. x² = 9² + 4²

Find the squares

x² = 81 + 16

x = √97 = 9. 85 miles

10. Length of the diagonal is the hypotenuse side

x² = 10² + 10²

x² = 100 + 100

x = √200 = 14.14 feet

11. The height of the pole is the opposite side

y² = 15² - 5²

y² = 225 -25

y = √200 = 14. 14 feet

12. the height of the pole is the opposite side

y² = 14² - 4²

y² = 196 - 16

y = √190 = 13. 78  feet

Jack is ten years older than Anna. Seven years from now Jack will be twice as old as Anna. How old is Jack now?

Answers

Jack is 13 years old now.

To solve this problem, we can use algebra to set up an equation and solve for Jack's age. Let's let J represent Jack's age now, and A represent Anna's age now.

According to the problem, Jack is ten years older than Anna, so we can write:
J = A + 10

Seven years from now, Jack will be twice as old as Anna, so we can write:
J + 7 = 2(A + 7)

Now we can substitute the first equation into the second equation to solve for A:
A + 10 + 7 = 2(A + 7)
A + 17 = 2A + 14
A = 3

Now that we know Anna's age, we can plug it back into the first equation to find Jack's age:
J = 3 + 10
J = 13

So Jack is 13 years old now.

Anna wants to create a miniature version of her dog. She will create it using the scale .25 inch = 1 foot. If her dog is 2.5 feet tall, how tall will her miniature version be?

Answers

Answer:

If 0.25 inch represents 1 foot, then 1 inch represents 4 feet (since 4 x 0.25 = 1).

Therefore, the height of the miniature dog in inches will be:

2.5 feet x 4 = 10 inches

So, the miniature version will be 10 inches tall.

Answer:

Her dog will be 5/8 of an inch tall. You would add 1/4 and 1/4 which equals 2/4. Then, you would split 1/4  = 1 in half so, 1/8 = 0.5
