If you meant 5.4 miles in a day, then the formula would be 250*5.4
The answer, then, would be 1350 miles.
W= width= L+5
L= length
Area= 204
Area= LW
204 square yards= LW
substitute w=L+5 for w
204= (L)(L+5)
204= L^2 + 5L
subtract 204 from both sides
0= L^2 + 5L - 204
factor
0= (L+17)(L-12)
0= L+17
-17= L
0= L-12
12 yards= L
WIDTH
Since the area cannot be a negative number, we'll use L=12 to find the width.
w=L+5
w=12+5
w=17 yards
CHECK:
204=(12)(17)
204=204
ANSWER: The length is 12 yards and the width is 17 yards.
Hope this helps! :)
Answer:
Step-by-step explanation:
<u>Find the area of the rectangle:</u>
- A = (3 + 12)*7 = 15*7 = 105 cm²
<u>Find the area of triangles:</u>
- A = 1/2(3 + 15 - 9)*7 = 1/2*9*7 = 31.5 cm²
<u>Find the shaded area:</u>
- A = 105 - 31.5 = 73.5 cm²
Answer:
28.5 miles per gallon
Step-by-step explanation:
399 miles / 14 gallons
= 28.5 miles/1 gallon
