Answer: the length of the field is 70 yards. The width of the field is 35 yards
Step-by-step explanation:
Let L represent the length of the rectangular athletic field.
Let W represent the width of the rectangular athletic field.
A rectangular athletic field is twice as long as it is wide. This means that
L = 2W
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
If the perimeter of the athletic field is 210 yards, it means that
210 = 2(L + W)
L + W = 210/2 = 105
Substituting L = 2W into L + W = 105, it becomes
2W + W = 105
3W = 105
W = 105/3 = 35
L = 2W = 2 × 35
L = 70

Step-by-step explanation:
y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio
proportion is an equation with a ratio on each side. It is a statement that two ratios are equal.
For example 2/5 is Equal to 4/10 this Would be A Example Of a Proportional relationship!
Answer:
$585
Step-by-step explanation:
Find 25% of $450:
$450 × 0.25 = $112.5 ⇒ this is how much money the business is donating.
Find 5% of $450:
$450 × 0.05 = $22.5 ⇒this is how much money the politician is donating.
Add those two amounts to the amount the student raised:
$450+$22.5+$112.5= $585
