Answer:

A(-5,9)

Step-by-step explanation:

Let A(a,b)

Since M is the midpoint then of A(a,b) and B(3,-5) then

M( (a+3)/2 , (b-5)/2)

But it is given that M(-1,2)

So (a+3)/2 = -1 which implies a=-5

and (b-5)/2=2 which implies b=9.

Therefore A(-5,9)

Tabatha is making hair bows for her cheer squad. She has 3 1/3 yards of pink ribbon. She needs a total of 35 feet of pink ribbon

rosijanka [135]

Answer:

Tabatha needs 25 feet of additional feet of pink ribbon to complete all the hair bows.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of pink ribbon Tabatha has = 3 1/3 yards

Amount of pink ribbon Tabatha needs to make all the hair bows = 35 feet

2. How many more feet of ribbon will Tabatha need to complete all the hair bows?

1 yard = 3 feet

3 1/3 yards = 10 feet

Additional feet of pink ribbon Tabatha needs = Amount of pink ribbon Tabatha needs to make all the hair bows - Amount of pink ribbon Tabatha has

Additional feet of pink ribbon Tabatha needs = 35 - 10

Additional feet of pink ribbon Tabatha needs = 25 feet

The answer is C BECAUSE for this question, you can think relatively. They give you the responses for 54 people surveyed, however they want the answer from 1,140 students. You can set up the proportion of 30/54 = x/1140 to find out the number of students agreeing to keep the mascot. You get 1900/3 or 633 1/3.

If tatianna works 3hrs a day on school days and make $123.75 a week what is her hourly rate?

madreJ [45]

Answer:

Her hourly rate is $8.25

Explanation:

Tatianna works 3 hours a day on school days and makes a total of $123.75 in a week

We know that:

There are 5 school days in a week

We are given that:

She works for 3 hours a day each of those days

Therefore:

Total number of hours worked = hours worked daily * number of days

Total number of hours worked = 3 * 5 = 15 hours in a week

The equation used to calculate Tatianna's earnings is:

Amount she makes in a week = Total number of hours worked * hourly rate

Now, we substitute with the givens to get the hourly rate as follows:

Amount she makes in a week = Total number of hours worked * hourly rate

123.75 = 15 * hourly rate

Hourly rate = $8.25
