Debra's rectangular vegetable garden measures 93 yards by 12 yards.

77julia77 [94]

Answer:

126 cups of fertilizer

Step-by-step explanation:

The complete question is

Debra's rectangular garden measures 9 1/3 by 12 yards .a bottle of fertilizer cost $14.79 .if Debra needs to mix 1/8 cup of fertilizer with water for each square foot of her garden how many cups of fertilizer does she need?

step 1

Find the area of the rectangular garden

The area of rectangle is equal to

$A=LW$

we have

$L=9\frac{1}{3}\ yd=9+\frac{1}{3}=\frac{9*3+1}{3}=\frac{28}{3}\ yd$

$W=12\ yd$

substitute

$A=(\frac{28}{3})12=112\ yd^2$

step 2

Convert square yards to square feet

Remember that

$1\ yd=3\ ft$

$1\ yd^2=9\ ft^2$

$112\ yd^2=112)9)=1,008\ ft^2$

step 3

Find how many cups of fertilizer does she need

using proportion

$\frac{(1/8)}{1}\ \frac{cups}{ft^2}=\frac{x}{1,008}\ \frac{cups}{ft^2}\\\\x=1,008/8\\\\x=126\ cups$

The measurement of the complement of an angle exceeds the measure of the angle by 25%. Find the measurement of the angle and its

tester [92]

Let the angles be A and C

Complimentary angles, therefor 
A + C = 90 

The measurement of the complement of an angle exceeds the measure of the angle by 25% (you used a % sign so I'll use % instead of degrees) 
C = 1.25A 

Substitute 
A + 1.25A = 90 
2.25A = 90 
A = 40º <----- 
C = 50º <----- 
------------------------------ 

If you meant 25º 
A + (A + 25) = 90 
2A + 25 = 90 
2A = 65 
A = 32.5º 
C = 57.5º
