Sophia and isabella get a reward of 117 dollars ina ratio of 1:8.What fraction of the reward does sophia get?

worty [1.4K]

Answer:

The amount of reward that Sophia receives is $\$13$

Step-by-step explanation:

Let

x------> amount of reward that Sophia receives

y-----> amount of reward that Isabella receives

we know that

$\frac{x}{y}=\frac{1}{8}$

$x=\frac{1}{8}y$ ------> equation A

$x+y=117$ -----> equation B

Substitute equation A in equation B

$\frac{1}{8}y+y=117$

$\frac{9}{8}y=117$

$y=117*8/9=\$104$

Find the value of x

$x=\frac{1}{8}(104)=\$13$

1. John began his job making $25 the first day. After that he was paid $6.75 per hour. a) Use the equation y 6.75x +25 to comple

iren [92.7K]

Answer:

a. Chart (attached)

b. and c. graph attached

Step-by-step explanation:

a. We use the equation given to us and plug in the values of "x" that have been shown to find the corresponding values of y.

So, when x=0, $y=6.75\times 0+25=25$

when x=20, $y=6.75\times 20+25=160$

when x=40, $y=6.75\times 40+25=295$

b. The graph has been shown in a similar manner. All the three points of part a are connected to form the straight line y=6.75x+25. So, we have (0,25), (20,160) and (40, 295)

c. The y axis is the earnings in dollars and the x axis is the number of hours worked.
