you have only nicole's and dimes in your piggy bank. when you ran the coins through a change counter, it indicated you have 595
Kryger [21]
Let's say the amount of nickels you have is hmm "n"

and the amount of dimes you have is "d"

there are 5cents in one nickel, so, if "n" is the total amount of nickels you have, that means 5 * n cents or 5n

there are 10cents in one dime, so, if "d" is the total amount of dimes  you have, that means 10*d or 10d

whatever 5n and 10d are, we know that their sum is 595
since the total amount the counter said you have is, only 595 cents

thus 5n + 10d = 595

solve for either, "d" or "n", and graph that

what are three likely combinations? well, just pick three points off that graph

10. rhombus abcd has vertices at a(-2, 7), b(8, 7), c(2, -1), and d (-8, -1).
horrorfan [7]

Answer: 80

Step-by-step explanation:

We can use the formula A=\frac{d_{1}d_{2}}{2}, where d_{1}, d_{2} are the lengths of the diagonals.

By the distance formula,

AC=\sqrt{(-2-2)^{2}+(-1-7)^{2}}=\sqrt{16+64}=4\sqrt{5}\\BD=\sqrt{(-8-8)^{2}+(-1-7)^{2}}=\sqrt{256+64}=8\sqrt{5}

So, the area is \frac{(4\sqrt{5})(8\sqrt{5})}{2}=\boxed{80}

Heather finished the 12-kilometer race in 2 hours. If Heather kept her pace constant, what was her rate? A. 24 km/hr. B. 14 km/h
andriy [413]

Answer: D, 6km/hr.

Step-by-step explanation:

Heather can finish a 12-kilometer race in 2 hours, and now we have to find how many kilometers she can ride/run at in 1 hour.

How many hours can Heather run in 1 hour? To solve that, we can use the equation 12 ÷ 2.

12 ÷ 2 = 6.

Therefore, if Heather keeps her pace constant, then her rate will be 6km/hr, or D.
