522 
Step-by-step explanation:
To find the surface area, we can find the area of each shape in the net.
There are 2 identical triangles and 3 different rectangles. Then we can add all of these areas together

Answer:
no
Step-by-step explanation:
2x + 3y ≥ 20
Substitute the point (2,5) in for x and y and see the inequality is true
2(2) +3(5) ≥ 20
4 + 15 ≥ 20
19 ≥ 20
This is not true, so (2,5) is not a solution
Answer:
k = 220
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 22 when x = 10
k = yx = 22 × 10 = 220
Answer:
true
Step-by-step explanation:
bc the integer equals to the subset
Okay. So, 15% is 15/100 and 33% is 33/100. 15 + 33 is 48. You leave the denominator the same, so the fraction is 48/100. However, the fraction needs to be simplified. Whatever you do to the numerator, we must do to the denominator. We can divide both numbers by 4 to get the simplified fraction form. 48/4 is 12. 100/4 is 25. There. The simplified fraction is 12/25. The answer is H: 12/25.
