The volume of this triangular prism is 32 cubic inches. What is the value of d?

krek1111 [17]

Answer:

Divide the volume by the length of the prism to get the area of the face:

468/13 = 36 square yards.

The area of the face ( triangle) is 1/2 x base x height

Replace with what you have:

36 = 1/2 x 9 x g

Multiply both sides by 2 to remove the 1/2:

72 = 9 x g

Divide both sides by 9 to find g:

g = 72 /9

g = 8 yards.

Solve 4x to the second power Minus 9

alexira [117]

$4x^2-9$

Here I have included 3 methods: Differentiating, Integrating and factorize

Differentiating:

$4x^2-9$

$2*4x^2^-^1$

$8x^2^-^1$

$= 8x$

Integrating:

$\int\limits 4x^2-9dx$

$\frac{4x^3}{3}-9x+C$

Factorise:

$(2x-3)(2x+3)$

If Andrea traveled 300 miles in 5 hours at what rate was she driving?

vladimir1956 [14]

Answer:

60 mph

Step-by-step explanation:

For this problem, we are looking at the rate, miles per hour. We know that Andrea traveled 300 miles in 5 hours, but how many miles did she travel in one hour? Let's do the math:

$300$ ÷ $5=60$ miles.

So, in one hours, Andrea travels 60 miles. We get the rate, 60mph.

Andrea was driving at 60 mph.

I hope this helps! Please let me know if you have any questions :)
