Brandon has a jar of quarters and dimes with a total value of $7.05. The number of quarters is 3 less than twice the number of d

miv72 [106K]

Answer:

quarters: 23
dimes: 13

Step-by-step explanation:

Let d represent the number of dimes. Then the number of quarters is 2d-3 and the total value of the coins is ...

0.10d + 0.25(2d-3) = 7.05

0.60d -0.75 = 7.05 . . . . . . . simplify

d = (7.05 +0.75)/0.60 = 13 . . . . add 0.75, divide by 0.60

2d-3 = 2·13 -3 = 23

Brandon has 23 quarters and 13 dimes.

PLEASE HELP

lisabon 2012 [21]

Step-by-step explanation:

The figure below shows a portion of the graph of the function $j\left(x\right) \ = \ 4^{x-2}$ , hence the average rate of change (slope of the blue line) between the $x$ and $x+h$ is

$\text{Average rate of change} \ = \ \displaystyle\frac{\Delta y}{\Delta x} \\ \\ \rule{3.7cm}{0cm} = \dsiplaystyle\frac{f\left(x+h\right) \ - \ f\left(x\right)}{\left(x \ + \ h \right) \ - \ x} \\ \\ \\ \rule{3.7cm}{0cm} = \displaystyle\frac{f\left(x + h\right) \ - \ f\left(x\right)}{h} \\ \\ \\ \rule{3.7cm}{0cm} = \displaystyle\frac{4^{x+h-2} \ - \ 4^{x-2}}{h} \\ \\ \\ \rule{3.7cm}{0cm} = \displaystyle\frac{4^{x-2+h} \ - \ 4^{x-2}}{h}$

$\\ \\ \\ \rule{3.7cm}{0cm} = \displaystyle\frac{\left(4^{x-2}\right)\left(4^{h}\right) \ - \ 4^{x-2}}{h} \\ \\ \\ \rule{3.7cm}{0cm} = \displaystyle\frac{\left(4^{x-2}\right)\left(4^{h} \ - \ 1 \right)}{h}$

If AOB = 70° and OC is the bisector of AOB then what is the measure of AOC?

Sonja [21]

<h3>Answer: 35°</h3>

Reason: The angle bisector cuts the original angle (70°) in half to get 70/2 = 35.
