CAN SOMEONE HELP ME WITH THIS?!

Answer:

The boxes of kazoos Mr. Jackson needs to order (26 + 24 + 30) ÷ 8.

We have given that,

There are 26-second graders, 24 third graders, and 30 fourth graders.

What is the expression?

An expression, in math, is a sentence with a minimum of two numbers and at least one math operation contain in it.

The amount of kazoos needed is 1 for every student

26 + 24 + 30

Since 8 come in each box, you divide by 8  

To get your answer of (26 + 24 + 30) ÷ 8.

For question 9, it's difficult to explain, so here's an image of what you're supposed to do (:

Answer:

Equal to

Step-by-step explanation:

Hello!

Let's simplify the left side:

Remember that the negative sign also means opposite, so the opposite of negative 9 is positive 9.

Let's simplfy the right side:

Remember that in an absolute value bracket, any positive value stays positive, but any negative value turns to the positive value.

So the inequality is 9 _ 9

Therefore the sign should be "=" as 9 is equal to 9.

Answer: by using the formula (pi)r^2

Step-by-step explanation:

the r stands for radius

Answer:

We are given an area and three different widths and we need to determine the corresponding length and perimeter.  

The first width that is provided is 4 yards and to get an area of 100 we need to multiply it by 25 yards.  This would mean that our length is 25 yards and our perimeter would be 2(l + w) which is 2(25 + 4) = 58 yards.

The second width that is given is 5 yards and in order to get an area of 100 yards we need to multiply by 20 yards.  This would mean that our length is 20 yards and our perimeter would be 2(l + w) which is 2(20 + 5) = 50 yards.

The final width that is given is 10 yards and in order to get an area of 100 yards we need to multiply by 10.  This would mean that our length is 10 yards and our perimeter would be 2(l + w) which is 2(10 + 10) = 40 yards.

Therefore the field that would require the least amount of fencing (the smallest perimeter) is option C, field #3.

Hope this helps!

Answer:

(-5,7)- Quadrant 2

(8 1/2,-4)- Quadrant 4

(0,5)-y axis

Step-by-step explanation:

Step 1:  Determine where the point lies

(-5, 7) has a negative x value which means that it's either in the second or third quadrant.  Now looking at the y value and it being positive we know that we are in the second quadrant.

(8.5, -4) has a positive x value which means that it's either in the first or fourth quadrant.  Now looking at the y value and it being negative we know that we are in the fourth quadrant.

(0, 5) has a x value of 0 which means that our point lies on the y-axis.

Mixed Number:

[tex]5\frac{1}{2}[/tex] or 5 1/2

Improper fraction:

2x5+1=11

[tex]\frac{11}{2}[/tex] or 11/2

Decimal:

5.5

5.5 because 5 is whole number, and then, 5 tenths because 5 is half of 10.

Percent:

1 whole = 100%

100% x 5 = 500%

500% + 50% (1/2) = 550%

550%

Answer:

A. 18.4

Step-by-step explanation:

The mean is the average. In order to find the answer you must add all the values of the variables and divide them by the number of variables. Simply just add 14, 15, 18, 20, and 25, and then divide it by 5 (the number of variables). Then you get your answer.

14+15+18+20+25=92

92/5=18.4

A. 18.4

Answer:

A. 18.4

Answer:

4 hours

Step-by-step explanation:

If the train travels at ~80 kilometers per hour, you just divide the total distance (in this case, 320 kilometers) by the speed traveled (80 kilometers). 320/80 = 4 hours.

Answer:

S(A) = 306 in²

Step-by-step explanation:

The surface area of a rectangular prism can be found using the following equation:

SA(rectangular prism) = 2(wl + hl + hw)

Note:

w = width = 6

h = height = 12

l = length = 4.5

Plug in the corresponding numbers to the corresponding variables:

SA(rectangular prism) = 2((6 * 4.5) + (12 * 4.5) + (12 * 6))

SA(rectangular prism) = 2((27) + (54) + (72))

SA(rectangular prism) = 2(27 + 54 + 72)

SA(rectangular prism) = 2(153)

SA(rectangular prism = 306

S(A) = 306 in²

Answer:

its y=x-2

Step-by-step explanation:

If you do -3-2=-5 and if you keep applying that rule you will find that it equals y.

The option that represents the matching representation of the function table is; B: y = x - 2

From the function table given, we see that;

At x = -3, y = -5

At x = -1, y = -3

At x = 0, y = -2

At x = 4, y = 2

At x = 7, y = 5

Looking at the options, the correct one is Option B which is;

y = x - 2

This is because it is the only one that produces all the correct output values of y for corresponding input values of x.

Finding deviation of each value

Mean Absolute Deviation (M.A.D.)

Answer:

1.20

Step-by-step explanation:

4 = |5 - 4| = 1

3 = |5 - 3| = 2

4 = |5 - 4| = 1

5 = |5 - 5| = 0

6 = |5 - 6| = 1

6 = |5 - 6| = 1

8 = |5 - 8| = 3

4 = |5 - 4| = 1

Answer: each number after the third number is the sum of the preceding three numbers. For example, if the first three numbers are 5, 6, and 7, then the fourth number is 18 because 5 + 6 + 7 = 18 and the fifth number is 31 because 6 + 7 + 18 = 31.

Answer:

x = 10

Step-by-step explanation:

Both obects are similar right. That means that they must have similar angles, similar sizes and similar scale factors.

For me by just looking at the figires I can conclude a similar scale factor which is 1.7. However we are going to calculate the scale factor.

First we must take notice that the triangle D'E'F' is an enlargement. So to find the scale factor we must the same sides of both triangle and divide the larger sid by the smaller side.

68 ÷ 40 = 1.7

Now that we have the scale factor (1.7) we can now find x.

The similer side D'F' = 17 and DF = x.

We are gonna use the scale factor to divide D'F' to find DF.

17 ÷ 1.7 = 10

Therefore x is 10
