Answer:
Distance between mall and library is 6.32 miles.
Step-by-step explanation:
Coordinates of the door to the library is at (2, 4) and door to the mall is at (8, 4).
Since, distance between two points
and
is given by,
Distance = ![\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
By this formula,
Distance between (2, 4) and (8, 4) will be,
Distance = ![\sqrt{(8-2)^2+(2-4)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%288-2%29%5E2%2B%282-4%29%5E2%7D)
= ![\sqrt{36+4}](https://tex.z-dn.net/?f=%5Csqrt%7B36%2B4%7D)
= ![\sqrt{40}](https://tex.z-dn.net/?f=%5Csqrt%7B40%7D)
= 6.32 miles
Answer:
see below
Step-by-step explanation:
If x represents the number of dimes, then 2x will represent twice the number of dimes. This is the number of quarters, since there are twice as many quarters as dimes.
There are 6 more nickels than dimes, so the number of nickels is 6 more than x. It is (x+6).
If we use the monetary values in cents, then the total of all coins is ...
25(2x) +10(x) + 5(x+6) = 485 . . . . . . matches choice D
Th answer is c. quotient, because it has to do with multiplication and not addition.
