Answer:
The length of the rectangle is 50 feet, while the width of the rectangle is 10 feet.
Step-by-step explanation:
Since the length of a rectangle is 5 times the width, to determine the length of the rectangle if the area is 500 square feet, the following calculation must be performed:
Area = Base x height
500 = X x 5X
500/5 = X x X
100 = X x X
100 = 10 x 10
X = 10
Thus, the length of the rectangle is 50 feet, while the width of the rectangle is 10 feet.
Roberto overtakes Juanita at the rate of (7.7 mi)/(11 h) = 0.7 mi/h. This is the difference in their speeds. The sum of their speeds is (7.7 mi)/1 h) = 7.7 mi/h.
Roberto walks at the rate (7.7 + 0.7)/2 = 4.2 mi/h.
Juanita walks at the rate 4.2 - 0.7 = 3.5 mi/h.
_____
In a "sum and diference" problem, one solution is half the total of the sum and difference. If we let R and J be the respective speeds of Roberto and Juanita, we have
R + J = total speed
R - J = difference speed
Adding these two equations, we have
2R = (total speed + difference speed)
R = (total speed + difference speed)2 . . . . . as computed above
Answer:
$1912.50
Step-by-step explanation:
5.5% of $1500 is 82.50
so 82.50×5(years)
=412.5 + 1500
=1912.50
Answer:4,1

I’m not sure lemme know
Answer:
-4
Step-by-step explanation:
Let us rearrange this equation by dividing both sides by (-3):
y=-4x-2
And since the equation of a line is y=mx+b, where slope=m,
then the slope of our line is -4
