Answer:

16

Step-by-step explanation:

The required value of 144 divided by 9 is 16.

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.

For example 4/2 = 2

We have to determine the value of 144 divided by 9.

As per the question,

⇒ 144 ÷ 9

⇒ 144 / 9

Apply the division operation, and we get

⇒ 16

Thus, the required value of 144 divided by 9 is 16.

Answer:

Well to start out you have 5 reindeer. If you glue Lancer and Ezekiel together you only have 4 units to arrange in different orders. That number is 24. But for each of those, Lancer and Ezekiel can be arranged in two ways... with Lancer in front of the pair or in the back of the pair. So altogether there are 48 ways to arrange the five reindeer with Lancer and Ezekiel always being together.

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.

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.

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.

Answer: B

Step-by-step explanation:

To solve this problem, we need to understand y-intercepts and slope.

Looking at the problem, we can automatically eliminate C and D. The graph has a negative slope because it is going down.

Now, let's look at the y-intercept. We see that the graph passes the y-axis at 1. Therefore, B is the correct answer.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 2.5}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ \frac{3}{x - 1} = 2}[/tex]

Do cross multiplication

[tex] \longrightarrow{ \sf{2(x - 1) = 3}}[/tex]

Distribute 2 through the parentheses

[tex] \longrightarrow{ \sf{2x - 2 = 3}}[/tex]

Move 2 to right hand side and change it's sign

[tex] \longrightarrow {\sf{2x = 3 + 2}}[/tex]

Add the numbers : 3 and 2

[tex] \longrightarrow{ \sf{2x = 5}}[/tex]

Divide both sides by 2

[tex] \longrightarrow{ \sf{ \frac{2x}{2} = \frac{5}{2}}} [/tex]

Calculate

Answer:

1.76

Step-by-step explanation:

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

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

Step-by-step explanation:

equal. where are you from?

If two alternate angles are formed on parallel lines, they are said to be b) equal.

Parallel lines are lines that never intersect, they are at equal distance from each other forever. If passed a transversal between the two parallel line, the angles forming have many relations like corresponding angles, alternate angles, co - interior angles or co - exterior angles.

Given in the question, we have alternate angles, maybe interior of the parallel lines or maybe exterior of the parallel line, but always on the opposite side of transversal. But, alternate angles are always equal to each other.

Thus option b is correct.
