What is the surface area of the prism? A. 144 - 1

Answers

Answer 1
Answer: If you want to find the surface area of something and it doesn't have a formula, just look at the area of each side individually and add them up!

The area of a triangle is equal to bh/2 = 16*6/2 =  48 in²
The area of the other triangle would be the same = 48 in²
The lateral side that's 10 by 9 inches = 10 * 9 = 90 in²
The other lateral side that's 10 by 9 is also = 90 in²
The lateral side that's 16 by 9 inches = 16 * 9 = 144  in²

144 + 90 + 90 + 48 + 48 = 420 in²
Answer 2
Answer:

The area of the prism is 420 in. You just have to add 144 + 90 + 90 + 48 + 48 which is equal to 420 in². You just had to add the sides

Hope it helps :)

A circle has an area of 48in squared what is the radius of the circle use 3 for pie

Answers

The radius of the circle is 4 in. The formula for the area of a circle is \pi r^(2) with r meaning radius. So if we use 3 for pi. Then r^(2) is 16. So r is 4.

X – 4y = 7 5x + 9y = 6 (4 points) A(3, –1)
B(3, 1)
C(1, –3)
D(–1, –3)

Answers

The solution to the given system of equations is (3, –1). The correct answer is option A.

The system of equations is given as:

x - 4y = 7   ....(1)

5x + 9y = 6 ....(2)

Solve the first equation for x:

x = 7 + 4y

Substitute the value of x in the second equation:

5(7 + 4y) + 9y = 6

35 + 20y + 9y = 6

29y = -29

y = -1

Substitute the value of y back into the first equation to find x:

x = 7 + 4(-1)

x = 7 - 4

x = 3

Therefore, the solution to the system of equations is x = 3 and y = -1.

Thus, the correct answer is option A.
