Answer:(-4,0)

Step-by-step explanation:

Given

Point A (6,-4)

Reflection of Point A about line y=-2 is

A' (6,0)

If any Point is reflected about any line y=constant then its x coordinate remains same

Now reflection of Point A' about x=1 is

A'' (-4,0)

If any point  is reflected about line x=constant then its y coordinate remains same

Answer: 35 additional teachers are needed

-------------------------------------------------
-------------------------------------------------

Explanation:

We have 2470 students and the ratio of students to teachers is 26:1. This means that for every teacher, there are 26 students. Put another way, we can set up this ratio

2470/x = 26/1

where x is the number of teachers. Cross multiply and solve for x

2470/x = 26/1
2470*1 = 26*x
2470 = 26x
26x = 2470
26x/26 = 2470/26
x = 95

So we have 95 teachers currently

-------------

Let y be the new number of teachers needed to bring the ratio down to 19:1

Using a similar idea as done above, we would have this ratio

2470/y = 19/1

Let's solve for y
2470/y = 19/1
2470*1 = 19*y
2470 = 19y
19y = 2470
19y/19 = 2470/19
y = 130

So we'll need 130 teachers to have the ratio be 19:1

The difference of the values is y - x = 130 - 95 = 35, which is the final answer. This is the additional amount of teachers needed.

1. The ratio of the number of boys to the number of girls on the swim team
Papessa [141]

Answer:

8

Step-by-step explanation:

Sum the parts of the ratio 4 + 2 = 6 parts

Divide 24 by 6 to find the value of one part of the ratio

24 ÷ 6 = 4 ← value of 1 part, thus

number of boys = 4 × 4 = 16

number of girls = 2 × 4 = 8

Hence there are 8 more boys than girls
