Two boxes have the same volume. One box has a base that is 5cm by 5cm. The other box has a base that is 10cm by 10 cm. How many times as tall is the box with the smaller base?

Answer:

Option B. x = 13

Step-by-step explanation:

In this question, we shall give a separate diagram which will help us to further understand the question.

Please see attached photo for further details.

To find the value of x we shall use the pythagoras theory as illustrated below:

x is the longest side Therefore,

x² = 12² + 5²

x² = 144 + 25

x² = 169

Take the square root of both side

x = √169

x = 13

Therefore, the value of x 13.

A) Let's solve for x. [tex]y^2-7=2xy[/tex]

Step 1: Flip the equation.

[tex]2xy = y^2 - 7[/tex]

Step 2: Divide both sides by 2y.

[tex]\frac{2xy}{2y} = \frac{y^2- 7}{2y}[/tex]

[tex]x = \frac{y^2- 7}{2y}[/tex]

Answer : [tex]x = \frac{y^2- 7}{2y}[/tex]

~~~~~~~~~~~~~

B) Let's solve for y. [tex]2x^2+3=xy[/tex]

Step 1: Flip the equation.

[tex]xy = 2x^2 + 3[/tex]

Step 2: Divide both sides by x.

[tex]xy = \frac{2x^2 + 3}{x}[/tex]

[tex]y = \frac{2x^2 + 3}{x}[/tex]

Answer : [tex]y = \frac{2x^2 + 3}{x}[/tex]

Answer:

2nd option

Step-by-step explanation:

plugging the values of x as 0,1,2,3,4,5 will help to find the exact equation

x= 0 , 199

x=1, 199* 1.25 =248.75 (approximately)

x=2, 199* (1.25)^2 = 310.9 (approximately)

x=3, 199* (1.25)^3 = 388.67 (approximately)

x=4, 199* (1.25)^4 = 485.83 (approximately)

x=5, 199* (1.25)^5 = 607.29 (approximately)

Answer:

Step-by-step explanation:

Given the system of equation, x + 4 y = 14. and 3 x + 2 y = 12, to solve for x, we can use the elimination method of solving simultaneous equation. We need to get y first.

x + 4 y = 14............ 1 * 3

3 x + 2 y = 12 ............ 2  * 1

Lets eliminate x first. Multiply equation 1 by 3 and subtract from equation 2.

3x + 12 y = 42.

3 x + 2 y = 12

Taking the diffrence;

12-2y =42 - 12

10y = 30

y = 3

From equation 1, x = 14-4y

x = 14-4(3)

x = 14-12

x = 2

It can be seen that the easiest way to get the value of x is by using the first equation and we are able to do the substitute easily because the variable x has no coefficient in equation 1 compare to equation 2 as such it will be easier to make the substitute for x in the first equation.

Answer:

A: The easiest to solve for is x in the first equation.

Step-by-step explanation:

Answer:

a) 8.8 square centimetres

b) 31.8 square centimetres

c) (3a + 12) square centimetres

d) Area = (2b + 2c + 4) square centimetres

Step-by-step explanation:

a) We have to split the diagram into three separate rectangles as shown below.

The area of A:

Area = 5.3 * 1 = 5.3 square centimetres

The area of B:

Area = 3.3 * 1 = 3.3 square centimetres

The area of C:

Area = 2 * 1 = 2 square centimetres

The area of the shape is the sum of the areas of the three shapes:

Area = 5.3 + 3.3 + 2 = 8.8 square centimetres

b) We have to split the diagram into two separate rectangles as shown below.

Note:(The diagram has conflicting values for 2.6 and 2.1 but I went with 2.6 as it seems more feasible in the diagram)

The area of A:

Area = 3 * 2.6 = 7.8 square centimetres

The area of B:

Area = 6 * 4 = 24 square centimetres

The area of the shape is the sum of the areas of the two shapes:

Area = 7.8 + 24 = 31.8 square centimetres

c) The shape is a rectangle and so its area is:

Area = 3 * (a + 4) = (3a + 12) square centimetres

d) The shape is a trapezium and so its area is:

Area = 0.5(A + B)H

where A =  c cm

B = b + 2 cm

H = 4 cm

The area of the shape is therefore:

Area = 0.5 * (c + b + 2) * 4

Area = 2 * (b + c + 2)

Area = (2b + 2c + 4) square centimetres

Answer:

7.5 jars

Step-by-step explanation:

There are 25 students in the art class.

Mr Jones is planning that for the project, each of the 25 students will need 0.3 jar of paint.

The amount of paint Mr Jones needs for this project is therefore the product of the number of students in the class by the amount of paint each student needs.

That is:

25 * 0.3 = 7.5 jars of paint

Mr Jones needs 7.5 jars of paint for the art project.

Answer:

[tex]\boxed{u = 13.7}[/tex]

Step-by-step explanation:

Using cosine rule

[tex]c^2 = a^2+b^2-2ab\ CosC[/tex]

Here c = u, a = 9 , b = 21 and C = 28

[tex]u^2 = 9^2+21^2-2(9)(21)\ Cos 28\\u^2 = 81+441-(378)(0.88)\\u^2 = 522 - 333.75\\u^2 = 188.24[/tex]

Taking sqrt on both sides

u = 13.7

Answer:

u ≈ 13.7

Step-by-step explanation:

Using the Cosine rule in Δ STU, that is

u² = s² + t² - 2stcosU

Here s = 21, t = 9 and U = 28°, thus

u² = 21² + 9² - (2 × 21 × 9 × cos28°)

   = 441 + 81 - 378 cos28°

   = 522 - 378 cos28° ( take the square root of both sides )

u = [tex]\sqrt{522-378cos28}[/tex]

   ≈ 13.7 ( to the nearest tenth )

Answer:

Step-by-step explanation:

Hello,

For the step 1:

We multiply the first equation by 3 and the second equation by 2, so we are using the Multiplication Property of Equality.

For the step 2:

To eliminate the x we subtract the first equation to the second one, so we are using the Subtraction Property of Equality.

For the step 3:

We divide by -16 both parts of the equation, so we are using the Division Property of Equality.

For the step 4:

We replace y in the initial first equation, we we are using the Substitution Property of Equality.

For the step 5:

We just Simplify.

For the step 6:

We add 4 to both parts of the equation, so we are using the Addition Property of Equality.

For the step 7:

We divide by 2, so we are using the Division Property of Equality.

Hope this helps.

Answer:

The answer is B.

Step-by-step explanation:

Since x < 1 the circle at the point is open and the arrow points infinitely in the negative direction (which happens to be answer A here)

x is also greater than or equal to -1 so a closed circle at the point -1 will complete this graph.

====================================================

Explanation:

Each cube has a side length of 4. Placed together like this, the total horizontal side combines to 4+8 = 8. This is the segment HP as shown in the diagram below. I've also added point Q to form triangle HPQ. This is a right triangle so we can find the hypotenuse QH

Use the pythagorean theorem to find QH

a^2 + b^2 = c^2

(HP)^2 + (PQ)^2 = (QH)^2

8^2 + 4^2 = (QH)^2

(QH)^2 = 64 + 16

(QH)^2 = 80

QH = sqrt(80)

Now we use segment QH to find the length of segment EH. Focus on triangle HQE, which is also a right triangle (right angle at point Q). Use the pythagorean theorem again

a^2 + b^2 = c^2

(QH)^2 + (QE)^2 = (EH)^2

(EH)^2 = (QH)^2 + (QE)^2

(EH)^2 = (sqrt(80))^2 + (4)^2

(EH)^2 = 80 + 16

(EH)^2 = 96

EH = sqrt(96)

EH = sqrt(16*6)

EH = sqrt(16)*sqrt(6)

EH = 4*sqrt(6), showing the answer is choice C

-------------------------

A shortcut is to use the space diagonal formula. As the name suggests, a space diagonal is one that goes through the solid space (rather than stay entirely on a single face; which you could possibly refer to as a planar diagonal or face diagonal).

The space diagonal formula is

d = sqrt(a^2+b^2+c^2)

which is effectively the 3D version of the pythagorean theorem, or a variant of such.

We have a = HP = 8, b = PQ = 4, and c = QE = 4 which leads to...

d = sqrt(a^2+b^2+c^2)

d = sqrt(8^2+4^2+4^2)

d = sqrt(96)

d = sqrt(16*6)

d = sqrt(16)*sqrt(6)

d = 4*sqrt(6), we get the same answer as before

The space diagonal formula being "pythagorean" in nature isn't a coincidence. Repeated uses of the pythagorean theorem is exactly why this is.

Answer:

C

Step-by-step explanation:

The dependent variable is always graphed on the y-axis and the independent variable is always graphed on the x-axis. Therefore, the dependent and independent variables are total price ($) and number of boxes respectively which makes the answer C.

Answer:

C. The total price depends on the number of boxes.

Step-by-step explanation:

In a graph, the x-variable is the independent variable; it is what you can change.

The y-variable is the dependent variable; its value depends on the value of the x-variable.

In this case, the y-variable is the total price of cupcakes, which depends on the x-variable, the number of boxes. C is your answer.

Answer:

first blank = 10 (for table 1)

second blank = 30 (for table 2)

====================================================

Explanation:

You could use a calculator to determine the value of b, then compute b^x for that first box. But as the instructions state, we don't need to use one. Why is that? Because the tables provide enough information to fill in the blanks.

Table 1 shows x = 2.096 lead to some unknown y value. Meanwhile, table 2 has x = 10 lead to y = 2.096; note the 2.096 shows up again. The exponential and log functions are inverses of each other. They undo each other's operation. This is similar to how division undoes multiplication, and vice versa.

Going in reverse of table 2, we will conclude that 10 must go in the blank for table 1. Therefore, b^x = 10 when x = 2.096

------------

Similarly, we will have 30 in the blank for table 2. Table 1 shows x = 3.096 lead to y = 30. Table 2 is the reverse of that as it is the inverse.

Throughout either section, we didn't need to find the value of b.

The missing value in table 1 is 10 and for table 2 it is 30.

The exponent indicates the power to which a base number is raised to produce a given number called a logarithm.

In another word, a logarithm is a different way to denote any number.

In the first table first column

x = 0.369 and bˣ = 1.5 ⇒

By logarithm

logbˣ = log1.5

xlogb = log1.5

Now x = 0.369

logb = 0.1760/0.369

b = 3

Now,

f(x) at x = 2.096 ⇒ [tex]3^{2.096}[/tex] = 10

And

x at g(x) = 3.096

[tex]log_{3}[/tex]x = 3.096 ⇒ x = 30.

Hence "The missing value in table 1 is 10 and for table 2 it is 30".

Answer: $60

Step-by-step explanation:

Given the following :

Total cost of renting a personal water craft = $64.20

Sales tax charged = 7%

Let the pretax cost = y

Therefore,

total cost = pretax cost + tax

$64.20 = y + 7% of y

$64.20 = y + 0.07y

$64.20 = 1.07y

y = $64.20 / 1.07

y = $60

Therefore, the rental cost of a personal watercraft for half an hour before tax is $60

Answer:

[tex]y=\frac{1}{3} x+7[/tex]

Step-by-step explanation:

We need to find the equation of a line perpendicular to [tex]y=-3x-3[/tex], which passes through the point (-3, 6).

Recall that a line perpendicular to a line of the form: [tex]y=mx+b[/tex], must have a slope which is the opposite of the reciprocal of the slope of the original line. that is, a slope of the form;

[tex]slope=-\frac{1}{m}[/tex]

Then, in our case, since the original line has slope "-3", a perpendicular line to it should have a slope given by:

[tex]slope=-\frac{1}{-3} =\frac{1}{3}[/tex]

We now know the slope, and also a point for this new line, so we use the point-slope form of a line:

[tex]y-y_0=m_\perp\,(x-x_0)\\y-6=\frac{1}{3} (x-(-3))\\y-6=\frac{1}{3} x+\frac{3}{3} \\y-6=\frac{1}{3} x+1\\y=\frac{1}{3} x+7[/tex]

Option C. 3√3

Step-by-step explanation:

Please see attached photo for brief explanation.

In the attached photo, we obtained the following:

Opposite = a

Adjacent = 3

Hypothenus = 6

Angle θ = 60°

We can obtain the value of 'a' as follow:

Tan θ = Opposite /Adjacent

Tan 60° = a/3

Cross multiply

a = 3 x Tan 60°

But: Tan 60° = √3

a = 3 x Tan 60°

a = 3 x √3

a = 3√3

Therefore, the length of the altitude of the equilateral triangle is 3√3.
