Answer:
960
Step-by-step explanation:
if each triangle is .25 square centimeters, and you can double them up to make a square that is .5 square cm, you only have to find the area of the grid by doing 
and then multiply it by four to get 960. it gets multiplied by four because if you double up the trianglse, its multipling the ammount used by two, and then you have each is .5 cm, which you can then make into one whole square cm by doubling up again, or just multiply by four.
1. To solve this exercise you must apply the formula for calculate the volume of a rectangular prism and the formula for calculate the volume of a rectangular pyramid:
2. Volume the rectangular prism:
V1=LxWxH
V1=(7 in)(3 in)(4 in)
V1=84 in³
3. Volume of the rectangular pyramid:
V2=BxH/3
B=(7 in)(3 in)=21 in
H=12 in-4 in=8 in
V2=(21 in)(8 in)/3
V2=56 in³
4. The volume of the composite figure is
V=V1+V2
V=140 in³

Answer: 662.50 dollars
==========================================================
Explanation:
If she doesn't sell a single thing, she still earns the base weekly salary of $310. This is the smallest amount she can earn per week.
If she does make sales, then she'll earn an additional 0.075x dollars where x is the amount of sales made (the total value of the merchandise). The 0.075 is the decimal form of 7.5%
In total, she makes 0.075x+310 dollars per week. In this case, she sold x = 4700 dollars worth of goods, which means,
0.075x+310 = 0.075*4700+310 = 662.50
She earned 662.50 dollars for that week.
It depends on what the question looks like. If it looks like this:
(6-3)(2/5)=
(3)(0.4)=
1.2
