Hello!

To solve this, find the cost of a single light bulb first, by dividing 9 / 5.

9 / 5 ==> 1.80

One light bulb is $1.80

Now, multiply 1.80 by 7.

1.80 * 7 = 12.6

7 light bulbs cost $12.6

Hope this helps! ☺♥

Find the value of x in the triangle shown below.
DIA [1.3K]

Answer:

x=8

Step-by-step explanation:

We can use the Pythagorean theorem to solve

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

6^2 + x^2 = 10^2

36 + x^2 = 100

Subtract 36 from each side

36-36 +x^2 = 100-36

x^2 = 64

Take the square root of each side

sqrt(x^2) = sqrt(64)

x = 8

During a heavy rainstorm, a city in Florida received 12 1/2 inches of rain in 25 1/2 hours. What is the approximate rainfallrage
alexdok [17]
We need to divide the number of inches by the number of hours.
Let's first convert the two numbers into fractions.

12 1/2 = 25/2

25 1/2 = 51/2

(25/2) / (51/2) = 25/2 * 2/51 = 50/102 = 25/51 = 0.49

The average rainfall was approximately 0.5 inches per hour.
