Answer:

8.06

Step-by-step explanation:

So for this one we are just going to take the two points (0,0) and (8,1), and plug them into the formula for distance which is d= $\sqrt{(x_{2} -x_{1})^{2} +(y_{2}-y_{1})^{2}$

$\sqrt{(1_{} -0_{})^{} +(8_{}-0_{})^{2}$ =8.06226

Then just round it

8.06

Jackie is reading a 252 page novel for her summer reading project. On Monday she reads 4/8 of the novel. On Tuesday she reads 28

natima [27]

So far, Jackie has read 217 pages

In order to determine the total number of pages Jackie read, we would have to determine the number of pages she read each day and add these pages together

Number of pages she read on Monday = $\frac{4}{8}$ x 252 = 126 pages
Number of pages she read on Tuesday = 28 pages
Number of pages she read on Wednesday = $\frac{1}{4}$ x 252 = 63 pages

The total number of pages she has read so far = 126 + 28 + 63 = 217 pages

Which equation can be used to solve for the rate, r, for Sam to change all the light bulbs in the office building by himself?

Bad White [126]

Answer:

$\frac{3}{r}+\frac{3}{8}=1$

Step-by-step explanation:

Given question is incomplete; here is the complete question.

Working together, Sam and Charlie can change all light bulbs in the office building in 3 hours. It would have taken Charlie 8 hours to do the job alone. Which equation can be be used to solve for the rate 'r', for Sam to change all the light bulbs in the office building by himself.

Let Sam can change the bulbs in the office alone in 'r' hours

Per hour work done by Sam alone = $\frac{1}{r}$

Let Sam takes he time to change the same bulbs in the office alone = 8 hours

Per hour work done by Sam = $\frac{1}{8}$

Since, Sam and Charlie complete the work together in time = 3 hours

Therefore, per hour work done by both = $\frac{1}{3}$

Equation for per work done by both will be,

Per hour work done by both = Per hour work done by Sam alone + Per hour work done by Charlie

$\frac{1}{r}+\frac{1}{8}=\frac{1}{3}$

Therefore, equation for the rate 'r' will be,

$\frac{1}{r}+\frac{1}{8}=\frac{1}{3}$

$\frac{3}{r}+\frac{3}{8}=1$

Somebody please help me on multiple step equations with parenthesis.

mash [69]

Answer:

k = 8

Step-by-step explanation:

8(10 - k) = 2k

First, distribute within the parenthesis,

80 - 8k = 2k

Add 8k to both sides of the equation

80 = 10k

Divide both sides by 10 to get your answer

8 = k

I hope this helps :)
