Answer:
A. 3cm by 3cm by 2cm or 6cm by 3cm by 1cm
B. 3cm by 3cm by 2cm
Step-by-step explanation:
POSSIBLE DEMENSIONS
3cm by 3cm by 2cm = 18cm^3
6cm by 3cm by 1cm = 18cm^3
LEAST AMOUNT OF MATERIAL
3 by 3 by 2 would mean 6cm squared of material per side
6 + 6 + 6 + 6 + 6 + 6 = 6 times 6 = 36
Total : 6 sides = 36cm^2 used
6 by 3 by 1 would mean 2 sides of 6cm^2, 2 sides of 3cm^2 and 2 sides of 18cm^2
18 + (6 + 6) + (3 + 3) =
18 + 12 + 9 =
30 + 9 = 39
Total: 39cm^2

Find the area...
A. 54 sq in
B. 60 sq in
C. 72 sq in
Answer:
60 sq inches
Step-by-step explanation:
Okay, here we are given two different shapes. One being a rectangle, and the other being a triangle. We are trying to find the area of the two shapes combined and in order to do so here are the steps:
The area of a rectangle is as follows:
[tex]b*h=A[/tex]
The area of a triangle is as follows:
[tex]A= \frac{1}{2} b*h\\or \\A=\frac{b*h}{2}[/tex]
Note: Notice how rectancgles have coensideing sides. Meaning that the opposite side of 9in will be 9 in and the opposite side of 6 in will be 6in.
Now lets solve the problem:
[tex]b*h =A\\6*9=54 sq inches\\A=\frac{1}{2} b*h\\A=\frac{1}{2} 6*2\\A=\frac{1}{2}(12)\\A=6 sq inches\\6+54=60 sq inches[/tex]

The scatter plot shows the maximum noise level when different numbers of people are in a stadium. The linear model is given by the equation y=1.5x + 22.7 where y represents maximum noise level and x represents the number of people, in thousands, in the stadium.
1. The slope of the linear model is 1.5. What does this mean in terms of the maximum noise level and the number of people?
2. A sports announcer states that there are 65,000 fans in the stadium. Estimate the maximum noise level. Is this estimate reasonable? Explain your reasoning.
3. What is the -intercept of the linear model given? What does it mean in the context of the problem? Is this reasonable? Explain your reasoning.
Answer:
The y intercept is 1.5x+22.7 + the linear equation which is 22
