Grapes cost $4.99 for 4 pounds at the supermarket.They 6.99 for 6 pounds at food mart.Witch store has a better deal?

Answers

Answer:

The grapes at the food mart are cheapest.

Step-by-step explanation:

First, you need to find out the cost for just one pound of grapes. You take $4.99 and divide it by 4 (the number of pounds) to get about $1.25 per pound from the supermarket. Now you do the same thing for the food mart. $6.99 divided by 6 is about $1.17. Therefore, the grapes at the food mart are cheaper.

For a field trip 11 students rode in cars and the rest filled eight buses. Which equation below will help you find how many students were in each bus if 315 students were on the trip? 11x + 8 = 315 315 + 8x = 11 8x + 11 = 315

Answers

Answer:

8x + 11= 315

Step-by-step explanation:

Let x = the number of students in a bus

There are 8 buses

8x is the number of students in buses

There are 11 students in cars

Add this together to get all the students, which is 315

8x + 11= 315

Answer:

8x + 11 = 315

Step-by-step explanation:

Note: There are 315 students in all. The expression being created will equal this amount.

11 of the students rode in cars, so they will be excluded from the bus amount. Add those at the end (+11).

It is given to us that there are 8 buses in all. You are solving for the amount of students in each bus, which is signified by x. As there are 8 buses, you will multiply the two together: 8x

8x + 11 = 315 is your answer.

Flying with the wind, a plate went 251 km/h. Flying into the same wind, the plane only went 219 km/h. What is the speed of the wind?

A. 8 km/h
B. 15 km/h
C. 26 km/h
D. None of the above.

Answers

Answer: Option D, the actual speed of the wind is 16km/h.

Step-by-step explanation:

Let's define two quantities:

Sp = Speed of the plane, that we assume it is constant.

Sw = Speed of the wind, that we assume it is constant.

When the plane flies with the wind, the total speed will be

Sp + Sw = 251km/h.

When the plane flies against the wind, the total speed will be:

Sp - Sw = 219km/h.

Then we have two equations:

Sp + Sw = 251km/h

Sp - Sw =  219km/h.

We want to find the speed of the wind, so we should isolate the speed of the plane in one of the equations, let's isolate it in the second equation:

Sp = 219km/h + Sw.

Now we can replace this into the other equation:

Sp + Sw = 251km/h.

(219km/h + Sw) + Sw = 251km/h.

2*Sw + 219km/h = 251km/h

2*Sw = 251km/h - 219km/h = 32km/h

Sw = (32km/h)/2 = 16km/h.

This is really close to the option B, but is not equal, so the correct answer will be D, none of the above.

What is half of the world’s population

Answers

Answer:

3,900,000,000

Step-by-step explanation:

The current global population is 7,800,000,000.

Half of this is 3,900,000,000.

I searched up the world’s population, and google says the world has an approximate population of 7,800,000,000

So to find half of the world’s population, divide 7,800,000,000 by two.

So, half of the world’s population is 3,900,000,000

When a set of coordinates on a preimage is multiplied by -n instead of n, the coordinates of the image rotate about the center of dilation by 180°. Consider all the potential intervals of n in the table. Enter information in the table to indicate whether the scale factor produces an enlargement, a reduction, or no size change. Also indicate whether the image rotates 180° about the center of dilation. The first one has been done for you.

Find the mean absolute deviation of the set of data. 2, 4, 4, 6, 8? PLEASE NOW

Answers

Answer:

1.76

Step-by-step explanation:

The mean absolute deviation of the set of data. 2, 4, 4, 6, 8 is 1.76.

How to calculate the mean absolute deviation?

Firstly, we need to calculate the mean of the numbers. This will be:

= (2 + 4 + 4 + 6 + 8)/5

= 24/5

= 4.8

The absolute deviation from the mean will be:

= (2.8, 0.8, 0.8, 1.2, 3.2).

Therefore, mean absolute deviation of the set of data will be:

= (2.8 + 0.8 + 0.8 + 1.2 + 3.2)/5

= 1.76
