80% of 25
percent means parts out of 100
'of' means multiply
80% of 25 means
80/100 times 25=40/50 times 25=20/25 times 25=20
answer is 20 problems
ANSWER
36√3 square units.
EXPLANATION
The area of a parallelogram is obtained by multiplying the base by the height.
We use the sine ratio to obtain the height.



The area becomes:

The ODE is linear:


Multiplying both sides by
gives

Notice that the left side can be condensed as the derivative of a product:

Integrating both sides with respect to
yields


Since
,

so that

Answer:
distributive property

the complete question in the attached figure
<span>we have to find the surface area first</span>
<span>the area of the base is A1------- > 5*2=10 ft</span>²
A2 (area of two rectangles faces)---------- > 2*3+2*4=14 ft²
A3 (area of the two triangles faces)
base of triangle------------ > 5---------- > (x)+(x-5)
x²+h²=3² ------------ > h²=9-x²
(5-x)²+h²=4²----------- > h²=16-(5-x)²
9-x²=16-(5-x)²-------------- >9-x²=16-25-10x-x²----------------- > x=1.8
h²=9-(1.8)²------------ > h=2.4 ft
A3= (5*2.4)*2/2=12 ft²
the surface area total=A1+A2+A3=10+14+12=36 ft²
if $0.22 ------------------------ > 1 ft²
X----------------------------------> 36 ft²
X=36*.22=$7.92
the answer is $7.92
