Answer:

1) 3/4

2) 15 days

Step-by-step explanation:

A has completed 3/12 = 1/4 of the work

B can do the work in 20 days.

Since 3/4 of the work is left,

He needs (3/4)×20 = 15 days to complete the remaining work

A line segment on a number line has its endpoints at -9 and 6. Find the coordinate of the midpoint of the segment.. . A. 1.5. *

Lyrx [107]

By definition, the midpoint is given by:
$m = (\frac{x1+x2}{2}, \frac{y1+y2}{2})$

Part A:
For the line segment we have:
$m = \frac{-9+6}{2}$
$m= \frac{-3}{2}$
$m = -1.5$
Answer:
the coordinate of the midpoint of the segment is:
B. -1.5

Part B:
For line segment HX we have:
$m = (\frac{-1+7}{2}, \frac{3-1}{2})$
$m = (\frac{6}{2}, \frac{2}{2})$
$m = (3,1)$
Answer:
the coordinates of the midpoint of the segment is:
A. (3,1)

Brooke saved the same amount of money each week for four weeks. She made this table to show how much money she saved.

Musya8 [376]

Answer:

In 10 weeks of time, Brooke would earn $ 20.

Step-by-step explanation:

Here, according to the table:

The money saved in week 1 = $ 2 = $(1 x 2)

The money saved in week 2 = $ 4 = $ ( 2 x 2)

The money saved in week 3 = $ 6 = $ ( 3 x 2)

The money saved in week 4 = $ 8 = $ ( 4 x 2)

So, by the graph relation, we can see that:

The amount saved in n weeks = ( n x 2) dollars

So, the amount saved by Brooke in 10 weeks is:

Put n = 10, we get:

The money saved = 2 n = 2 x 10 = $ 20

Hence, in 10 weeks of time, Brooke would earn $ 20.
