Simora [160]

Answer:

Step-by-step explanation:

10000*7%= $700.00

2500-700=1800

1800 is 10% of 18,000

So 18,000 +10,000 = 28,000 in sales is needed to get $2,500 in commission.

Use the number line. Enter the integer value that point D represents.

GenaCL600 [577]

Given:

A number line from -10 to 10 with 20 tick marks.

Point D is 1 tick mark to the left of 5.

To find:

The integer value that represents point D.

Solution:

A number line from -10 to 10 with 20 tick marks. It means, each mark represents the integer values from -10 to 10.

We know that, as we move towards left on a number line the value decreases and as we move towards right the value increases.

Point D is 1 tick mark to the left of 5. It means, point D represents the integer value which is 1 less than 5.

$5-1=4$

Therefore, point D represents the integer 4.

Goshia [24]

Answer: $\overline{QC}\cong\overline{Q'C'}$ and $\angle{ACQ}$ is a right angle .

Step-by-step explanation:

Given : A reflection is a transformation that maps point Q in a figure over a line, AB, such that for point C at the intersection of AB and QQ'.

We know that reflection creates a image equidistant from the line of reflection.

Thus, $\overline{QC}\cong\overline{Q'C'}$

Also in reflection , a line drawn from the point is perpendicular to the line of reflection.

Therefore, $\angle{ACQ}$ is a right angle
