Answer:

x = 4 sqrt(2)

Step-by-step explanation:

This is a right triangle so we can use trig functions

sin theta = opp/ hypotenuse

sin 45 = 4/x

Multiply x to each side

x sin 45 = 4/x *x

x sin 45 = 4

Divide each side by sin 45

x sin 45 / sin 45 = 4 /sin 45

x = 4/ sin 45

We know sin 45 = sqrt(2)/2

x = 4/ sqrt(2) /2

x = 8/ sqrt(2)

We do not leave a sqrt in the denominator so multiply by sqrt(2)/ sqrt(2)

x = 8/ sqrt(2) * sqrt(2)/sqrt(2)

x = 8 * sqrt(2) /2

x = 4 sqrt(2)

slega [8]

Answer:

  • - 2 5/12

Step-by-step explanation:

  • −3 2/3 = x − 1 1/4
  • x = - 3 2/3 + 1 1/4
  • x = - 2 - 2/3 + 1/4
  • x = - 2 - 8/12 + 3/12
  • x = - 2 - 5/12
  • x = - 2 5/12

an oil company drilled several walls.fifty wells, or 25%,produced oil.what was the total number of wells that were drilled
Phantasy [73]
25% is equal to 100/25=1/4

We can substitute this into an equation to get the total number of wells where n can be equal to the total number of wells.

1/4*n=50
n/4=50
n=50*4
n=200

The total number of wells that were drilled was 200.
