Answer:

The soccer team must wash 49 cars in order to gain at least $300.

Step-by-step explanation:

The soccer team started out by paying $84.55.  They charge $8 per car wash.  So let's say how many cars they washed was x.  They need to gain at least $300 dollars.  If we put this in an equation it looks like this (we are solving for x):

8x - 84.55 >or= 300

To find x we have to do the following steps:

8x - 84.55 >= 300

    + 84.55     + 84.55

8x >= 384.55

/8          /8

x >= 48

Now we have to make sure that this is correct:

8 * 48 - 84.55 = ?

384 - 84.55 = 299.45

Since 299.45 is less than 300, x must be greater than 48, but since 299.45 is so close to 300, my educated guess would be that x=49.  

8 * 49 - 84.55 = ?

392 - 84.55 = 307.45

Since 307.45 is greater than 300, x=49.  So we can conclude that they must wash 49 cars to profit at least $300.

Answer: 20.28 cm^2

Explanation:

First find the area of the square!

7 x 2 = 14

then find the area of the circle!

We know that the DIAMETER of the circle is 4 because the total length of the square is 7 cm and there are 3cm of length on the sides of the circle

so 7-3 = 4

Then to find the area of a circle you need to use this formula:

r = radius

A = 3.14r^2

3.14(2)^2 = 12.57

Then you need to divide it by TWO because its a half circle!

12.57 / 2 = 6.285

14 + 6.285 = 20.28 cm^2

I hope this helped!

Answer:

[tex]Area = 49\frac{25}{36}[/tex]

Step-by-step explanation:

Given

Tile

[tex]Length = 4\frac{5}{6}[/tex]

[tex]Width = 2\frac{1}{3}[/tex]

See attachment for dimension of the floor

Required

Determine the area covered by the carpet

From the attachment, the dimension of the floor is:

[tex]Length = 12\frac{1}{4}[/tex]

[tex]Width = 5[/tex]

Calculate Area

[tex]Area = Length * Width[/tex]

[tex]Area = 12\frac{1}{4} * 5[/tex]

[tex]Area = 61\frac{1}{4}[/tex]

The area of the tiles is:

[tex]Area = 4\frac{5}{6} * 2\frac{1}{3}[/tex]

[tex]Area = \frac{29}{6} * \frac{7}{3}[/tex]

[tex]Area = \frac{203}{18}[/tex]

[tex]Area = 11\frac{5}{18}[/tex]

So, the carpet area is:

[tex]Area = Floor\ Area - Tile\ Area[/tex]

[tex]Area = 61\frac{1}{4} - 11\frac{5}{18}[/tex]

To improper number

[tex]Area = \frac{245}{4} - \frac{208}{18}[/tex]

Take LCM

[tex]Area = \frac{2205 - 416}{36}[/tex]

[tex]Area = \frac{1789}{36}[/tex]

[tex]Area = 49\frac{25}{36}[/tex]

Answer:

[tex]P(CD) = \frac{1}{10}[/tex]

Step-by-step explanation:

Given

[tex]AK = 10[/tex]

See attachment for line AK

Required

Probability of choosing CD

From the attachment:

[tex]CD=D-C[/tex]

[tex]CD=3 - 2[/tex]

[tex]CD = 1[/tex]

So:

[tex]P(CD) = \frac{CD}{AK}[/tex]

[tex]P(CD) = \frac{1}{10}[/tex]

Answer:

Federcio's age possible values are those that are greater than 14 i.e 15, 16, 17 and so on

Step-by-step explanation:

Let Federico's age = x

Three times the difference of Federico’s age, and 4 means:

3(x - 4)

Increased by 7:

3(x - 4) + 7

Is greater than 37:

3(x - 4) + 7 > 37

Solving the inequality:

3x - 12 + 7 > 37

3x - 5 > 37

3x > 37 + 5

3x > 42

x >42/3

x > 14

Federcio's age possible values are those that are greater than 14

Answer:

The area of the pyramid is 703.97 ft²

Step-by-step explanation:

The lateral area of a right square pyramid is given as;

[tex]A_l =a \sqrt{a^2 + 4h^2}[/tex]

where;

a is base length

h is the vertical height of the pyramid

The vertical height of the pyramid is calculated as follows;

the vertical height passes through the center of the base.

half of the base = 8 ft

the slant height = hypotenuse side of the right triangle = 22 ft

Thus; h² = 22² - 8²

h² = 420

h = √420

h = 20.493 ft

The area of the pyramid is calculated as;

[tex]A_l =a \sqrt{a^2 + 4h^2}\\\\A_l =16\sqrt{16^2 + 4(20.493)^2} \\\\A_l = 703.97 \ ft^2[/tex]

Therefore, the area of the pyramid is 703.97 ft²

Answer:

4 streamlined shapes reduces friction on airplane

A streamlined shape reduces friction on an airplane. The correct statement is 4.

The process of making choice is by identifying the correct decision, gathering information, and assessing alternative solutions.

To determine the correct statement will be

1. Friction is a force causing rotation.

The statement is incorrect because the cause of rotation is force.

2. Efficiency of the lever is a highly efficient 1st class lever.

The statement is incorrect.

3. Torque is output divided by input.

The statement is incorrect because the output divided by input is known as productivity.

4. Streamlined shape reduces friction on an airplane.

The statement is correct.

5. Equal-arm balance loss of energy.

The statement is incorrect.

Answer:

7.5

Step-by-step explanation:

the term similar triangles means they have the same angles and the same scale factor so if we look at rs and jl you see they are 12 and 6. thats is a scale factor of .5 so you take 15 and multiply it by .5 or you can divide it by 2.

Answer:

-14x + 30y + 4

Step-by-step explanation:

-6x + 4(-2x + 8y) - 2y + 4

take out the parentheses

4(-2x + 8y) = -8x + 32y

-6x - 8x + 32y - 2y + 4

solve for the x's then y's

-6x - 8x = -14x

32y - 2y = 30y

The value of the quotient of 50 and 5 subtracted from 20 that can be given as 10.

It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.

Firstly, we have the quotient of 50 and 5. This can be written as

[tex]\dfrac{50}{5}[/tex]

And we know that this can be written as 10.

Now we subtract it from 20. Then we have the number 20 and we subtract 10 from it. Then it can be written as

20 - 10

On subtracting, we have

20 - 10 = 10.

Choose 1 answer:

A [tex]\hat y=10x+20[/tex]

C [tex]\hat y=-20x+20[/tex]

Based on this equation, estimate the score for a student that spent 3.8 hours studying.

Answer:

[tex]\hat y = 20x +20[/tex]

Score of 96 for studying 3.8 hours

Step-by-step explanation:

Given

See attachment for graph

From the straight line of trend, we have:

[tex](x_1,y_1) = (0,20)[/tex]

[tex](x_2,y_2) = (2,60)[/tex]

The slope (m) is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{60 - 20}{2 - 0}[/tex]

[tex]m = \frac{40}{2}[/tex]

[tex]m = 20[/tex]

The equation is calculated using:

[tex]\hat y = m(x - x_1) + y_1[/tex]

This gives:

[tex]\hat y = 20(x - 0) +20[/tex]

[tex]\hat y = 20(x ) +20[/tex]

[tex]\hat y = 20x +20[/tex]

Solving (b): When study hours is 3.8

This means that [tex]x= 3.8[/tex]

So:

[tex]\hat y = 20x +20[/tex]

[tex]\hat y = 20 * 3.8 + 20[/tex]

[tex]\hat y = 96[/tex]
