Answer: $15,000

Step-by-step explanation:

This is basic proportions.

Therfore 100%=X.

Using the formula of proportions, we can calculate (9000*100)/60

This gives up 15000

Therfore he paid $15,000 for his car, which is 100% of the price.

A wall in a classroom has a length of 16 ft and a diagonal of 20 ft. A student is painting a rectangular mural on the wall. The mural has a length of 6 ft and a diagonal of 10 ft. What is the difference between the width of the wall and the width of the mural?
ill mark you brainliest pls help!
Answer choices:
A. 2ft
B. 4ft
C. 10ft
D. 14ft

Answers

Answer:

B. 4 ft

Step-by-step explanation:

First, find the width of the wall.

The length, width, and diagonal form a right triangle, where the diagonal is the hypotenuse and the length and width are the 2 legs.

Use the pythagorean theorem and solve for a, the width of the wall.

a² + b² = c²

a² + 16² = 20²

a² + 256 = 400

a² = 144

a = 12

So, the width of the wall is 12 feet.

Solve for the width of the mural. Again, the diagonal, length, and width form a right triangle.

Use the pythagorean theorem again and solve for a, the width of the mural:

a² + b² = c²

a² + 6² = 10²

a² + 36 = 100

a² = 64

a = 8

So, the width of the mural is 8 feet.

Now, find the difference between the widths of the wall and mural:

12 - 8

= 4

So, the difference between the two widths is B. 4 ft

Answer is...B 4 ft....

a.) x = # of bottles
Fill It Up, Inc.: y = 4x
Bottles by Bob, Co.: y = 3x + 25

b.) x is the independent variable, and y is the dependent variable because it depends on the value of x. See picture below for graphs.

c.) Not sure if the class size is given, but if there are less than 25 students then Fill It Up, Inc. would be cheapest. However, if there are more than 25 students then Bottles by Bob, Co. would be cheapest. This is shown in the graph. The class size influenced the decision.

d.) The intersection in the graphs at point (25, 100) shows that for 25 bottles the price will be the same ($100).

Sumo-Sumo Gas Company has a tanker-truck for hauling gasoline. The cylindrical tank has a
diameter of 5.4 meters. The tank is 16 meters long. How many cubic meters of gas can the truck
haul?

Answers

Answer: 366.2 cubic meters

Step-by-step explanation:

The cylinder is just a circle but extruded in the 3rd dimension.

The Volume of a cylinder = Area of Circle * Height

V of Cylinder = [tex]\pi[/tex][tex]r^{2}[/tex] * height

r = radius

The radius is half of diameter

Diameter = 5.4 meters

Radius = 5.4 / 2 meters = 2.7 meters

V = 3.14 * [tex]2.7^{2}[/tex] * 16

V = 3.14 * 7.29 * 16

V = 366.2 Meters Cubed

Find the constant of proportionality for the table of values and write in the form y = kx

A) y = 1/4x

B) y = 4x

C) y = 6x

D) y = 24x

Answers

Answer:

Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Number of lemons used is denoted by 'y'.

Number of glasses of lemonade is denoted by 'x'.

As we can observe that ,

[tex]\frac{6}{24} = \frac{8}{32} = \frac{7}{28} = \frac{2}{8} = \frac{4}{16} = \frac{1}{4} \\[/tex]

so we can write i as

[tex]\frac{x}{y} = \frac{1}{4}[/tex]

By cross multiplication

y=4x

So, if write it in the form y=kx,

It will be y=4x.

The correct answer is B) y = 4x

How can the addition porperty of equality be used to solve substraction equations? (Please answer correctly)(no links)

Answers

Answer:

just as you can add the same value to each side of an equation without changing the meaning of the equation, you can subtract the same value from each side of an equation.

by-step explanation:

x+7=42

Since 7 is being added to the variable, subtract 7 to isolate the variable.

To keep the equation balanced, subtract 7 from both sides of the equation.

x+7=42

-7 over x+0

-7 over 35

so answer is 35

There are 6 fiction books in the bin. The probability of randomly selecting a fiction book from the bin is 0.6 or 3/5.

Step-by-step explanation:

The third bullet point says that the probability of selecting a poetry book is 1/5, and the second point says that the probability of selecting a fiction book is three times as likely than the poetry books. So that would mean we must multiply 1/5 by 3. So do that you could turn it into a decimal first. 1/5 as a decimal is 0.2. Next, we multiply it. So 0.2 times 3 equals 0.6. Therefore the answer is 0.6. And to convert that back to a fraction, it would be 3/5.

The standard recommendation for automobile oil changes is once every 3000 miles. A local mechanic is interested in determining whether people who drive more expensive cars are more likely to follow the recommendation. Independent random samples of 49 customers who drive luxury cars and 38 customers who drive compact lower-price cars were selected. The average distance driven between oil changes was 3178 miles for the luxury car owners and 3200 miles for the compact lower-price cars. The sample standard deviations were 41.80 and 50.60 miles for the luxury and compact groups, respectively. Assume that the population distributions of the distances between oil changes have the same standard deviation for the two populations.
