GIven:522 miles in 9 hours.

So if we divide 522 by 9 we get that Kira drives 58 miles per hour.

Now in 7 hours Kira just drives 7 times that which means Kira drives.

58*7=406 miles

Hope this helped!

Step-by-step explanation:

Distance travelled in 9 hours = 522 miles

Distance travelled in 1 hour = 522/9 = 58 miles

Distance travelled in 7 hours = 7 * 58 = 406 miles

Hope it will help :)

First let's review how to find the surface area of a rectangular prism. Since the opposite faces have the same area, we just need to find one of each pair of faces and multiply the result by 2.

One face in each pairs adds up to 6*4+2*4+2*6=24+8+12=44

Now we just need to multiply this by 2!

44*2=88 cm^2

I really hope my explanation helped, if there are any more question about this please ask me in the comments I will answer them.

Answer:

18

Step-by-step explanation:

x + (2+x)+ (3x) =82

x+x+3x= 82-2

5x=80

x= 16

Answer:

She has enough sugar.

Step-by-step explanation:

Let x = cups of sugar needed

eggs/cups of sugar = 2/4 = 1/2

12 eggs/x = 1/2

24 = x

Since she as 25 cups available and she needs 24 cups, it looks like she has enough sugar with 1 cup left over.  I hope she is making chocolate chip cookies.

$5012.02 is the value of the car after 10 years

Depreciation is the reduction in the value of an asset over time

Given that: the present value of a car is $18,000 and it's depreciating at a rate of 12% per year

The exponential function is given as

Y= a ( 1 - r )^t

where a = present value of a car, r =  depreciation rate and t = number of years

Y = 18,000 (1-0.12)¹⁰

Y = $ 5012.02

Therefore, the value of the car after 10 years is $ 5012.02

Answer:

37.3 m

Step-by-step explanation:

Let the distance of the coin to the base of the building be represented by x. Applying the required trigonometric function, we have:

Tan θ = [tex]\frac{Opposite}{Adjacent}[/tex]

Tan 15 = [tex]\frac{10}{x}[/tex]

0.2680 = [tex]\frac{10}{x}[/tex]

x = [tex]\frac{10}{0.2680}[/tex]

  = 37.3134

x = 37.3 m

The distance of the coin from the base of the building is 37.3 m.
