Answer:

Total Interest = $3.08

Step-by-step explanation:

A = P (1 + r/n)^(nt)

A = 30(1+.05/1)^(1*2)

A = 33.08

We want to find interest only so subtract principal amount from total value

33.08-30 = 3.08

Total Interest = $3.08

Total Value = $33.08

Step-by-step explanation:

Remark

The Perimeter of a rectangle is found using

P = 2L + 2w

Givens

L = s+2t

w = s + 5t

Solution

P = 2(s + 2t) + 2(s + t5)                     Remove the brackets

P = 2s + 4t + 2s + 10t                       Combine

P = 4s + 14t

Answer P = 4s + 14t                         This cannot be reduced any further.

Answer:

x = 150

y = 30

Step-by-step explanation:

x° = 5y° (corresponding angles) (1)

x° + y° = 180° (Linear pair angles) (2)

From equations (1) and (2), we find:

5y° + y° = 180°

-> 6y° = 180°

-> y° = 180°/6

-> y° = 30°

-> y= 30

-> x° = 5(30°) = 150° (From equation 1)

-> x = 150

Answer:

Step-by-step explanation:

We can draw a Venn diagram to represent the data.

First, identify the groups.

Then draw the Venn diagram to represent the groups.

Given 73 students study all subjects:

E ∩ M ∩ S = 73   (add this to the middle section)

Next, add the numbers for the sections where the students study 2 topics.

E ∩ M but not S:  152 - 73 = 79

M ∩ S but not E:  79 - 73 = 6

S ∩ E but not M:  139 - 73 = 66

Now complete each circle by making sure that the values add up to the total value given.

Only E = 254 - S ∩ E - E ∩ M - E ∩ M ∩ S = 254 - 66 - 79 - 73 = 36

Only M = 280 - E ∩ M - M ∩ S - E ∩ M ∩ S = 280 - 79 - 6 - 73 = 122

Only S = 280 - M ∩ S - S ∩ E - E ∩ M ∩ S = 280 - 6 - 66 - 73 = 135

To find the total number of students in the school, add the numbers in each section of the Venn diagram:

73 + 79 + 6 + 66 + 36 + 122 + 135 = 517

Answer:

i am not sure but i think it is 280

The equation that represents the number of T-shirt , number of colours of shirt and total order is 3x + 50xy.

The number of colours and T- shirts are the variable quantity while the cost of order is the fixed quantity.

The number of members in the school choir = 75

The charge for one shirt = $3

Let the number of T-shirts ordered be x

Cost of ordering x shirts = 3x

Therefore,

Charge for each colour to be printed = $50

Let the number of colours to be printed on each T- shirt be represented by y

Therefore,

Cost of printing y colours on each T- shirt = 50y

Cost of printing y colours on x number of T-shirts = x(50y) = 50xy

Hence, the equation that represents the number of T-shirt , number of colours of shirt and total order is as follows:

Total cost  = 3x + 50xy

Hence, the fixed quantity and variable quantity are as follows:

The number of colours on the shirts is a variable quantity

The number of shirts ordered is a variable quantity

The cost of order is fixed quantity

Answer:

  104 feet

Step-by-step explanation:

The Pythagorean theorem can be used to find the hypotenuse of a right triangle with legs 40 feet and 96 feet. It tells you ...

  h² = 40² +96²

  h² = 1600 +9216 = 10816

  h = √10816 = 104

The distance from one corner to the opposite corner is 104 feet.

______

Additional comment

You may recognize that the ratios of the given lengths are 40:96 = 5:12. These match the legs in the Pythagorean triple (5, 12, 13). This tells you the third side (diagonal) of the triangle is 13 ratio units, or 13×(8 ft) = 104 ft.

Answer:

In a pair of similar triangles, the corresponding sides are proportional. Corresponding sides touch the same two angle pairs. When the sides are corresponding it means to go from one triangle to another you can multiply each side by the same number

t - 6

Step-by-step explanation:

          t2 + 2t - 24

Simplify   ————————————

            t2 - 36    

Trying to factor by splitting the middle term

  Factoring  t2 + 2t - 24  

The first term is,  t2  its coefficient is  1 .

The middle term is,  +2t  its coefficient is  2 .

The last term, "the constant", is  -24  

Multiply the coefficient of the first term by the constant   1 • -24 = -24  

Find two factors of  -24  whose sum equals the coefficient of the middle term, which is   2 .

    -24    +    1    =    -23  

    -12    +    2    =    -10  

    -8    +    3    =    -5  

    -6    +    4    =    -2  

    -4    +    6    =    2    That's it

Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  6  

                   t2 - 4t + 6t - 24

 Add up the first 2 terms, pulling out like factors :

                  t • (t-4)

            Add up the last 2 terms, pulling out common factors :

                  6 • (t-4)

Step-5 : Add up the four terms of step 4 :

                  (t+6)  •  (t-4)

           Which is the desired factorization

Trying to factor as a Difference of Squares :

1.2      Factoring:  t2-36  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

       A2 - AB + BA - B2 =

       A2 - AB + AB - B2 =

       A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 36 is the square of 6

Check :  t2  is the square of  t1  

Factorization is :       (t + 6)  •  (t - 6)  

Canceling Out :

  Cancel out  (t + 6)  which appears on both sides of the fraction line.

Answer:

x = 0.71; y = 2.43

Step-by-step explanation:

y = 2x + 1

y = 9x - 4

9x - 4 = 2x + 1

7x = 5

x = 5/7

y = 2x + 1

y = 2(5/7) + 7/7

y = 10/7 + 7/7

y = 17/7

x = 0.71; y = 2.43

The length of arc FH in the circle 8.37 units.

In mathematics, a circle is a closed two-dimensional shape that consists of all the points in a plane that are a fixed distance (called the radius) from a given point (called the center). Circles are used in many areas of mathematics and science, including geometry, trigonometry, and physics. They have important applications in areas such as engineering, architecture, and computer graphics.

Here,

To find the length of arc FH, we first need to find the measure of angle FGH in degrees. Since the sum of angles in a triangle is 180 degrees, we can use the fact that angles FGH and FGF are supplementary to find:

m∠FGF = 180 - m∠FGH = 180 - 86 = 94 degrees

Since FGF is an inscribed angle that intercepts arc FH, the measure of arc FH is twice the measure of angle FGF. So we have:

m(arc FH) = 2 × m∠FGF = 2 × 94 = 188 degrees

To find the length of arc FH, we need to know the circumference of circle G. Since we know that FG = 16 units, we can use this to find the radius of the circle:

r = FG/2 = 16/2 = 8 units

The circumference of the circle is then:

C = 2πr = 2π(8) = 16π

To find the length of arc FH, we need to find the fraction of the circumference that arc FH represents, and then multiply this by the total circumference. Since the measure of arc FH is 188 degrees out of a total of 360 degrees in the circle, we have:

Length of arc FH = (188/360) × C

Substituting the value of C, we get:

Length of arc FH = (188/360) × 16π

Simplifying and rounding to the nearest hundredth, we get:

Length of arc FH ≈ 8.37 units

Answer:

Step-by-step explanation:

you are looking for perfect square factors of the numbers under the radical sign. both numbers and the sum are irrational because they contain √5

125 = 5×25

80 = 5×16

3√125 = 3√(25×5) = 3×5√5 = 15√5

√80 = √(16×5) = 4√5

1)  15√5 + 4√5 = 19√5      the √5 is the same square root so you add the coefficients

perfect square factors are bold

Using a system of equations, it is found that:

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

The theater was full, hence:

x + y + z = 277.

There are half as many adults as there are children, hence:

x = 2z.

The theater charges $5.00 for children, $7.00 for students, and $12.00 for adults. The total ticket sales were of $2002, hence:

5x + 7y + 12z = 2002.

Replacing the second equation into the other two:

y + 3z = 277 -> y = 277 - 3z

7y + 22z = 2002.

Then:

7(277 - 3z) + 22z = 2002

z = 63

y = 277 - 3z = 277 - 3 x 63 = 88

x = 2z = 2 x 63 = 126.

Step-by-step explanation:

Joint variation:

Q = kmT where k is a constant.

Subsituting the given values:

20930 = k*1*5

k = 20930 / 5 = 4186.

So the relation is:

Q = 4186mT

When Q = 8372 and T = 10:

8372 = 4186 * m * 10

m = 8372 / (4186*10)

m = 0.2 kg.
