Kobotan [32]

61122122061 miles

We can use an equation to find how much miles she would drive in one hour, then multiply by 111111 hours:

183183183/333 = 550099.65

550099.65 * 111111 = 61122122061 miles

Sixty photos taken at a photo shoot are in black and white. If this represents 15 percent of the total number of photos taken, w
Art [367]

Answer:

D. 15×4/100×4 = 60/400

Step-by-step explanation:

First I figured out how many photos there are in total, which was by doing 60/.15, since only 15% of the total photos are in black and white. We can already cross out all possibilities that don't have the denominator 400, but we can go a step further by seeing which one is 60/400, or equal to 60/400, which is D. 15×4/100×4 = 60/400.

Mice21 [21]

Answer:

$18.84

Step-by-step explanation:

The area of a cone is (1/3)pi*r^2*h

With all variables plugged in we get an area of (1/3)*3.14*(1^2)*9, or 9.42 cubic inches. With a value of 2$/in^3, we get 2*9.42, or 18.84.

Therefore, the value of the container is $18.84.

Plz help and show how you did the math question
Nikitich [7]

Answer:

x =  - 3

y =  - 2

Step-by-step explanation:

Since y=x+1 plug it into bottom equation as y.

x + 1= 5x + 13

Subtract 1 from both sides

x = 5x + 12

Subtract 5x from both sides

- 4x = 12

Divide both sides by -4

x =  - 3

Now x=-3 into the top equation to find y

- 3 + 1 =  - 2

y=-2
