A daycare center in Seaside currently has 9 assistant caregivers and 6 senior caregivers. Since demand is high, the owner is going to be hiring 1 assistant caregiver per month and 2 senior caregivers per month. Her goal is to have a larger staff, including an equal number of assistant caregivers and senior caregivers. How long will that take? How many of each type will there be?


After _____months, there will be_______ of each type of caregiver

Answers

After 3 months, there will be 12 of each type of caregiver

How to illustrate the equation?

An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.

Since the daycare center in Seaside currently has 9 assistant caregivers and 6 senior caregivers. Since demand is high, the owner is going to be hiring 1 assistant caregiver per month and 2 senior caregivers per month.

This will be:

9 + m = 6 + 2m

where m= number of months

Collect the like terms

2m - m = 9 - 6

m = 3

The number of caregiver will be:

9 + m

9 + 3

= 12

Write a brief summary about similar figures

Answers

Similar figures are the same shape but not the same size. you can find out the scale by using parallel lines.

Answer:

*You could just look it up.

Here's what I found on google:

Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent, and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.

So basically, similar figures are 2 figures that are the same shape.

They don't have to be the same size.

4. Bring down the dividend in the one's column and repeat it.

Step-by-step explanation:

Divide 3/5 by 1/2 as a reduced fraction.

Answers

Answer:

You can't divide two fractions together, so you multiply the second fraction by taking its reciprocal.

[tex]\frac{3}{5} * \frac{2}{1} \\\\= \frac{6}{5}[/tex]

If we divide the [tex]\frac{3}{5}[/tex] by [tex]\frac{1}{2}[/tex] so the decrease fraction should be [tex]\frac{6}{5}[/tex].

Given that,

The fraction is [tex]\frac{3}{5}[/tex].And, the other fraction is [tex]\frac{1}{2}[/tex].Now it should be divided to come as a reduced fraction.

So, the decreased fraction should be

[tex]= \frac{3}{5} \times \frac{2}{1} \\\\= \frac{6}{5}[/tex]

Therefore we can conclude that if we divide the [tex]\frac{3}{5}[/tex] by [tex]\frac{1}{2}[/tex] so the decrease fraction should be [tex]\frac{6}{5}[/tex].

Triangle PQR with coordinates P(3,-4), (6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically. What will
be the coordinates of P'Q'R'?

Answers

Answer:

(0, 2), (3, 5) and (3, 0)

Step-by-step explanation:

Since, Points P(3,-4), Q(6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically.

Therefore,

P' (3 - 3, - 4 +6) = P' (0, 2)

Q'(6 - 3, - 1 + 6) = Q'(3, 5)

R'(6 - 3, -6 + 6) = R'(3, 0)

Thus, the coordinates of P'Q'R are (0, 2), (3, 5) and (3, 0).

Answer:

P'(0, 2), Q'(3, 5), R'(3, 0)

Step-by-step explanation:

Given

Points P(3,-4), Q(6, -1), R(6, -6) Translation: x -3, y + 6

New points:

P'(3 - 3, -4 + 6) = P'(0, 2)Q'(6 - 3, -1 + 6) = Q'(3, 5)R'(6 - 3, -6 + 6) = R'(3, 0)
