Answer:
288
Step-by-step explanation:
To solve, we need to find the area of the four triangle sides and add that to the square base's area.
Area of triangle sides: base * height * 0.5
Area of square base: base * height
Substitute the values
8 * 14 * 0.5 = 56
There are four of these sides, so the area of all the triangles is 224.
The square base is 8 * 8, or 64
Add these two values together.
64 + 224 = 288
Thus, the answer is 288
Answer:
percent decrease
26%
Step-by-step explanation:
Yesterday you ran 5 miles
Today you ran 3.7 miles
The amount went down, so the percent decreased
The percent decrease = (original - new)/original * 100 %
= (5-3.7)/5 * 100%
= 1.3/5 * 100 %
=.26 *100%
= 26%
9 1/7 lb
You can convert the mixed numbers to solve it easier! :)
