Answer:
7 years
Step-by-step explanation:
Since a graph isn’t provided, I will indicate how many years are involved, and you should be able to deduce it from this. First, let’s [use a calculator] to find 2% of 250, which equals 5. Adding 5 to the total only slightly impacts 2% of the original amount, changing it by 0.1 or 5/50. We can continue adding 5 until we exceed 282, which occurs after 7 increments, calculated as (285 minus 250) divided by 5. Thus, the answer is indeed 7 years. A quick calculation will confirm this.
Response:
first option
Detailed explanation:
The equation expressing a proportional relationship is
y = kx ← with k as the proportional constant
Here k takes the value of 0.7, hence
y = 0.7x ← represents the required equation
Given
= 
(cross-multiply)
10y = 7x (dividing both sides by 10)
y = x = 0.7 x ← emerges as the needed equation
Answer:
B. The triangle.
Step-by-step explanation:
The number of sides decreases by one as you progress down the list.
Mel descends 50-35=15 feet in 5-2=3 seconds. Thus, her descent rate is 15/3=5 ft/sec.
Victor descends 60-50=10 feet in 4-1=3 seconds. Hence, his descent rate is 10/3=3⅓ ft/sec. Mel is faster, traveling at 5 ft/sec.
