Answer:
42 yards
Step-by-step explanation
There are 4 sides to a rectangle. 2 lengths, and 2 widths. That means that you multiply both values by 2 and then add them together, so 40 + 2. A more basic way to think of it is 20+20+1+1. Therefore, the perimeter is 41 yards.
Answer:
Step-by-step explanation:
If you had a solid cylinder, in order to find the amount of material that makes up that solid cylinder, you would find the volume using the radius of 4 (half of the diameter 8). BUT we want to know the volume of the solid with the radius of 4 minus the solid that has a radius of 2.5 (half of the diameter 5).
That's volume outer - volume inner. To find the outer volume:
so
and
and do the same for the inner volume:
and
Subtract the inner from the outer:
If you need your answer in decimal form, then the volume is
9189.16 cm³
Answer:
diện tích đa giác trong hình là :
186 cm2
Step-by-step explanation:
hãy tách hình đa giác trên thành 4 hình chữ nhật và tính diện tích từng hình chữ nhật
FIND SALE PRICE
= $230 - ($230*20%)
= $230 - $46
= $184
OR
= $230 * (100%-20%)
= $230 * 80%
= $184
*use the method you're most comfortable with or that your teachers prefer
FIND TOTAL WITH TAX
= $184 + ($184 * 11.5%)
= $184 + $21.16
= $205.16
ANSWER: The shoes with discount and taxes cost $205.16.
Hope this helps! :)
