B because 1 * 10^5 is equal to 100,000 as it moves 5 digits to the left (5 zeros)
Answer:
She drove 60 miles in 3 hrs. This means she drove (60/3 = 20)....20 miles per hr.
I paid $15 for 3 hamburgers. This means 15/3 = 5....it costs $5 per burger.
Step-by-step explanation:
After 100 more minutes, the rate has gone from 30 to 80, increasing by 50. 100 divided by 50 is 2 so for every 2 minutes she is charged one dollar, but per minute the rate is 50 cents per minute. Hope this helps :)
Answer:
C
Step-by-step explanation:
To determine which point lies on the graph, substitute the x-coordinate into f(x) and if the value is equal to the y-coordinate then the point is on the graph
A (15, 1)
f(15) = 3 × 
≠ 1 ← not on graph
B (0, 15)
f(0) = 3 × 
= 3 × 1 = 3 ≠ 15 ← not on graph
C (1, 15)
f(1) = 3 × 
= 3 × 5 = 15 ← lies on graph
D (0, 0)
f(0) = 3 × = 3 × 1 = 3 ≠ 0 ← not on graph
Answer:
Below in bold.
Step-by-step explanation:
The smaller one has side 2 and the corresponding side on the larger one is 5, so the answer is 2/5.
The individual sides and perimeter are one-dimensional, so:
The ratio of their perimeters is the same 2/5.
The ratio of their areas ( which is 2 dimensional) is 2^2/5^2 = 4/25.
