1)
Lateral area is the surface area, minus the bases. The area of a square is base times height. The lateral area is 112 centimeters squared, and the surface area is 336 centimeters squared.
2)
The bases of prisms are the triangles. The lateral area of the prism is 695 meters squared. The area of a triangle is base times height divided by 2. The surface area of the prism is 727 meters squared.
3)
The area of a circle is pir^2. The surface area of the cylinder is 1,230 inches cubed.
4)
The area of the pyramid is 790.
5)
The answer to number 5 is 2,254.
6)
The last answer is 21.7 centimeters. but I'm not like 100% sure.
Step-by-step explanation:
d=-1-5=-7+1=-6
BY using this equation:
a(n) = a1 +(n-1)d
and get the second term
a(2) = 17 +(2-1)-6
=11

Answer:
Question 1: 11%
Question 2: 89%
Question 3: 43%
Question 4: 11%
Step-by-step explanation:
Looking at picture 1, we need to find the crossing point between -1.2 and 0.05. That has 0.1056, which is the same as 10.56%. 10.56% rounds to 11%, so C is our answer.
Picture 2 has the same chart, but we just need to find the inverse, since the inequality sign is flipped. 100 - 10.56 is 89.44%, which rounds to 89%, so D is the answer for Picture 2.
Picture 3 has two tables. 0.73 has 76.73% and -0.41 has 34.09%. Subtract 34.09% from 76.73% to get 42.64% That rounds to 43%, so A is the answer.
Picture 4 essentially has the same expression as Picture 2 (only the sign has switched): P(z ≥ 1.25). The meeting point is 89.44%. Now, subtract that from 100 to get 10.56%, which rounds to 11%. C is our answer for Picture 4.
I hope this helps you! ^w^
Answer:
One answer is x = 1, y = -1, and z = 2.
