Answer:
A
Step-by-step explanation:
You can add the numbers to get the perimeter
10 1/3 + 15 2/3 = 26
18 1/4 + 24 1/4= 42 1/2
26 + 42 1/2= 68 1/2
That is answer choice A
Answer:
t=40
Step-by-step explanation:
The sum of all angles in a triangle will always equal 180°. This means that:
(2t-42)+(4t-49)+(2t-49) = 180°
Let's solve this equation!
(2t-42)+(4t-49)+(2t-49) = 180
First we simplify what's on the left side:
2t-42+4t-49+2t-49 = 180
2t+4t+2t-42-49-49 = 180
8t-140 = 180
*Add 140 to both sides
8t = 180+140
8t = 320
Divide both sides by 8 to know what t means:
t = 320/8
t = 40
165% of what? If you mean 165% of 1, that's 1.65, which is 1 and 13/20
Volume = Area x Height. We are given Volume and Area, so plug in and solve for Height (Height = Volume/Area)
18in^3 = 4.5 in^2 x Height (divide both sides by 4.5) -> 4in = Height
