Answer:

She can fill 1 and 1/4 tanks

Step-by-step explanation:

the reason she can fill 1 and 1/4 tanks is because if you multiply 5 by 12 you get 60 and then you multiply 4 by 12 and its 48 so 48/60 is what you get meaning that it takes her 48 minutes to fill one tank and 48 plus 12 is 60 and 12 is 1/4 out of 48 so you get 1 and 1/4 tanks she can fill in one hour.

The circumference of the top of the cake is $9.5\pi\approx29.845$ in.

It sounds like the baker is trying to line the circumference with cherriesto fit as many as possible along the border, like in the picture I've attached below.

This comes down to dividing the cake's circumference by the diameter of each cherry:

$\dfrac{9.5\pi}{0.75}\approx39.79$

or about 39 cherries, making the answer D.

An amusement park charges admission plus a fee for each ride. Admission plus 2 rides costs $10. Admission plus five rides costs

LenaWriter [7]

Answer:

The charge for admission is $6 and the charge for each ride is $2

Step-by-step explanation:

Let

x ----> the charge for admission

y ----> the charge for each ride

we have that

$x+2y=10$ -----> equation A

$x+5y=16$ -----> equation B

Solve the system by elimination

Subtract equation B from equation A

$x+2y=10\\-(x+5y)=-16\\---------\\2y-5y=10-16\\-3y=-6\\y=2$

Find the value of x

substitute the value of y in any equation

$x+2(2)=10$

$x+4=10$

$x=10-4$

$x=6$

therefore

The charge for admission is $6 and the charge for each ride is $2

The diameter of your bicycle wheel is 34 inches. How far will you move in one turn of your wheel? What is the distance covered i

irga5000 [103]

In one turn of the wheel, you will move the circumference of the wheel. To find the circumference, you just do π × diameter, so π × 34 = 106.8 inches. In 5 turns, you will just go 5 times the circumference, so you multiply by 5 to get 534.1 inches. I hope this helps!

Lily had 95 inches of yarn. After cutting 4 pieces that were each the same length, she had 15 inches of yarn left.

Each was 10 inches because she had 95 and 95-15=40 divided by 4 = 10
