The formula for a trapezoid is a= (l+w)/2 * h (substitute knowns) 3.9= (2.5+4)/2 *h. (solve for h) 3.9= 3.25* h 3.9/3.25= h h= 1.2 The height is 1.2cm in length

The right triangular prism has a volume of 1,152 cm3. What is the value of x, the height of the prism? 6 8 12 16
rusak2 [61]

volume = 1/2 x a x b x X

1152= 1/2 x 12x 12 x X

 12*12 = 144

1152 = 1/2 x 144 x X

1152/ 1/2 = 2304

2304 =144 x X

X=2304/144 = 16

check  1/2*12*12*16 = 1152

x=16cm

barxatty [35]

Answer:

100√65 yds

Step-by-step explanation:

The Pythagorean Theorem is a^2+b^2=c^2. In this case a=700, b=400, and c is the unknown.

  • 700^2+400^2=c^2
  • 490000+160000=c^2
  • 650000=c^2
  • c=√650000

√650000=√(100^2•65)=100√65
