Answer:

6 miles per hour

Step-by-step explanation:

speed = distance/time

speed = 1/2÷1/12 which is the same as

1/2 x 12/1 = 6

6 miles per hour.

or ou could change the 1/2 to become 0.5

and the 1/12 to become 0.083333333

and divide 0.5 ÷ 0.083333333 = 6.000000024

rounded to one decima place become 6.0

6 miles per hour

20 POINT QUESTION
MissTica

8x + 7y =89

2x + 5y=45

You want to be able to subtract one away from the other one so you are just left with either x or y. to do this we could multiply the bottom equation by 4

so you would get

8x+7y=89

8x + 20y= 180

Now we can subtract equation 1 from equation 2 so you get

13y=91

this gives you y=7 so to find x we can simply substitute y into an equation;

2x + 5x7=45

2x + 35= 45

2x = 10

x =5

so the final answer is y = 7/ x = 5

A company has cups for its water cooler. Each cup has a height of 14 cm and the base has a radius of 3 cm. How much water is nee
Nitella [24]

Answer:

125 cups can hold  49.5 liters of water.

Step-by-step explanation:

The volume of the cup will tell how much water is needed to fill each cup.

The volume of the cup can be determined by the formula

V= base area* height

V= πr²* h

V= 22/7 (3)² (14)

V= 396cm³

125 cups can hold 125 * 396 cm³= 49500cm³

But 1 cm³= 0.001 Liters

Therefore = 49500*0.001= 49.5 liters

125 cups can hold  49.5 liters of water.
