Charles and Seth are building a ramp for Sasha and Samantha. The base of the triangle is 11ft and it's height is 5ft. How long i
Arlecino [84]

Answer: 12.1 ft

Step-by-step explanation:

A ramp represents a right-angled triangle so Pythagorean formula can be used to find the diagonal length which will also be the hypotenuse.

c² = a² + b²

Where:

c = hypotenuse

a = base

b = Height

c² = 11² + 5²

c² = 121 + 25

c² = 146

c = √146

c = 12.1 ft

Mrs. Chip bought 2 sheets and a blanket and paid $41. Mrs. Dale bought a sheet and 4 blankets and paid $80.
Katyanochek1 [597]

Answer:

  • Sheet = $12
  • Blanket = $17

Step-by-step explanation:

<u>Let the cost of a sheet be s and cost of a blanket be b</u>

  • 2s + b = 41
  • s + 4b = 80

<u>From the first equation we get:</u>

  • b = 41 - 2s

<u>Substitute in the second equation</u>

  • s + 4*(41 - 2s) = 80
  • s + 164 - 8s =  80
  • 7s = 84
  • s = 12

<u>Then</u>

  • b = 41- 2*12 = 17

Solve for x in the following:<br> 8x^2 + 6x = -5
artcher [175]

Answer:

No solution or

(-3±2i\sqrt{31})/8

Step-by-step explanation:

To get the solution, move everything to the left side of the equation:

8x²+6x+5 = 0

If you try to factor the equation or graph it, you will see that it will never equal 0.

If you need an imaginary solution you can plug it into the quadratic equation:

-6±\sqrt{36-160} over 16

Simplify and you get

-6±i\sqrt{124} over 16

-6±4i\sqrt{31} over 16

Simplify the fraction and you can get

(-3±2i\sqrt{31})/8
