Answer:
5000
Step-by-step explanation:
let CP be x
8/100x = 400
x = 400*100/8
x = 5000
Therefore, CP is 5000
Answer:
a. Andrea is incorrect
b. By solving for x, we find that x does not equal 8, but it is equal to 7.
Step-by-step explanation:
8+4=2(x-1)
8+4=2x-2
12=2x-2
14=2x
x=7
Answer:
a=44, b= 58
Step-by-step explanation:
You look at the first triangle that gives you the two angles, and with the rule that every triangle's angles inside it need to add up to 180 degrees, you can determine that the missing angle is 46 degrees, which translates over to the other triangle, meaning that a would be 44 degrees.
The other triangle has two identical angles, being 61 degrees, which helps translate to the smaller triangle, again allowing you to infer that b is 58 degrees
Answer: 39.5 ft^2
Step-by-step explanation:
1. Find the area of the rectangle using the formula length * width
2. Find the area of one of the triangles (the top one) using the formula 1/2(b*h)
3. Find the area of the other triangle (the bottom one) using the formula 1/2(b*h)
- 3 ft * 3 ft * 0.5 = 4.5 ft
4. Add 'em all up to get the total area
- 32 ft + 3 ft + 4.5 ft = 39.5 ft ^2
