<h2>step</h2>

find Amy's speed

convert the minutes into hours by dividing by 60

\frac{2}{15 \times  \frac{1}{60} }  \\  = 8 \: miles \: per \: hour

find the number of miles ran by multiplying the speed by the time, ie

Rectangles F and H are similar. If rectangle F has dimensions of 5x10 and rectangle H has dimensions of 15 by an unknown amount.
enyata [817]

Answer:

The answer is 30 or 7.5

Step-by-step explanation:

There are two answers because you haven't specified whether the 15 corresponds with the 5 or the 10 so I did both.

If the 15 corresponds with the 5 then the scale factor is 3 because 15 ÷ 5 = 3. To find the unknown amount you have to multiply the 10 by 3 to get 30.

If the 15 corresponds with the 10 then the scale factor is 1.5 because 15 ÷ 10 = 1.5. To find the unknown amount you have to multiply the 5 by 1.5 to get 7.5.

So depending on whether the 15 corresponds to the dimension 5 or 10 you have two answer, you can use the one that applies to you.

Katie has a collection of nickels dimes and quarters with a total value of $4.20 there are 7 more dimes than nickels and six mor
Aneli [31]
Katie, Let the number of nickles = N Since there are 7 more dimes than nickles, the number of dimes D = N + 7 Since there are 4 more quarters than nickles, the number of quarters Q = N + 4 Since quarters = $0.25, dimes = $0.10, and nickles = $0.05 and all added together = $4.90 ⇒  0.25·Q + 0.10·D + 0.05·N = 4.90 Now multiply through by 100 to eliminate the decimal: 25Q + 10D + 5N = 490 Substitute for Q and D 25(N+4) + 10(N+7) + 5N = 490 25N + 10N + 5N +100 +70 = 490 40N + 170 = 490 ⇒ 40N = 320 ⇒ N = 320/40 N = 8, D = N+7 = 15 Q = N+4 = 12 Check: 25(12) + 10(15) + 5(8) = 300 + 150 + 40 = 490
