Answer:

15 cup

Step-by-step explanation

So i was thinking because each student gets 5 ounces and and there is 24 students. Which means first you have to:

24x5= 120

You know that there are 120 ounces in total but you have to find how many  cups the teacher has. So 120 ounces equals 15 cups im pretty sure.

Answer: 15 cups

Step-by-step explanation: ok this question sounds like it's going to be weird and complicated but it's not this question gave you information you do not need to trip you up ignore that the cornstarch and water don't matter what the question wants is cups of slime 5oz per student 24 students 5X24=120oz     120oz=15 cups

hope this helps

Answer- 3

Step-by-step explanation:

Answer:

1372 cubic ft.

Step-by-step explanation:

\(V=\frac{4}{3} \pi 7^3\)

\(V=\frac{4}{3} \pi 343\)

\(V=457\frac{1}{3} \pi\)

Since pi is 3 to find the approximate answer, do:
\(V=457\frac{1}{3} (3)\)

\(V=1372\)

Hence, the volume of the sphere is approximately 1372 cubic ft.

Answer:

V = 1,372 ft³

Step-by-step explanation:

You have been given the equation necessary for calculating the volume of a sphere:

\(V = \frac{4}{3} \pi r^{3}\)

In this formula, "V" represents the volume, "π" is the given value (3), and "r" is the radius. While you have not been given the radius, you have been given the diameter (14 ft). The radius is half of the diameter.

radius = diameter / 2

radius = 14 ft / 2

radius = 7 ft

Now, you can plug this value into the formula and simplify to find the volume.

 \(V = \frac{4}{3}\pi r^{3}\)                                         <----- Volume formula

\(V = \frac{4}{3} * (3) *r^{3}\)                               <----- Plug 3 in for "π"

\(V = \frac{4}{3} * (3) * 7^{3}\)                                <----- Plug 7 in for "r"

\(V = \frac{4}{3} * (3) * (343)\)                           <----- Solve 7³

\(V = 1,372 ft^{3}\)                                   <----- Multiply all the terms together

Answer:

Step-by-step explanation:

Answer:

\(M.A.D = 1\)

Step-by-step explanation:

Given

9, 7, 6, 8, 7, 5

Required

Mean Absolute Deviation

The first step is to calculate the mean of the given data;

\(Mean = \frac{\sum{x}}{n}\)

where x = 9, 7, 6, 8, 7, 5 and n = 6

\(Mean = \frac{9+ 7+ 6+ 8+ 7+ 5}{6}\)

\(Mean = \frac{42}{6}\)

\(Mean = 7\)

Subtract mean (7) from each data

\(9 - 7 = 2\\7 - 7 = 0\\6 - 7 = -1\\8 - 7 = 1\\7 - 7 = 0\\5 - 7 = -2\)

Return the absolute values of each

\(|2| = 2\\|0| = 0\\|-1| = 1\\|1| = 1\\|0| = 0\\|-2| =2\)

Calculate mean of the above absolute values

\(Mean = \frac{\sum{x}}{n}\)

\(Mean = \frac{2+0+1+1+0+2}{6}\)

\(Mean = \frac{6}{6}\)

\(Mean = 1\)

Hence, the mean absolute deviation of the given data is 1

Step-by-step explanation:

Answer:

Your answer is: (2,-1). I provided a picture in case you need to show your work.

Answer: (A) Yes

Step-by-step explanation:

        Let us look at the side lengths. When we are talking about scale copies, the lengths should stay proportionate from the original shape to the copy.

        Both of the figures are triangles. I will be looking at the length of their legs. Figure A has leg lengths of 4 and 3. Figure B has leg lengths of 8 and 6, respectively.

        This means Figure B is a scale copy of Figure A because 8/4=2 and 6/3=2. These mean the proportions stayed similar.

Answer:

40%

Step-by-step explanation:

2/5

2 and 5 multiplied by 10 is 20 and 50

20/50

a percentage has to be out of 100

50x2=100

but he have to do it to both sides

20x 2

40/100

we can change that now into a %

Answer:

Slope: 1   Y-intercept: 3   Y=1x+3    Change: y=1x

Step-by-step explanation:

The slope would be 1 because it is going at a constant rate. The Y-intercept would be 3 because it was already at 3 inches from last week's snow storm. The equation would change from y=1x+3 to y=1x because there wouldn't be 3 inches of snow from the snow storm.

Rate of flow =1in/hour

Snow earlier=fixed=y intercept=3in

Equation

m is slope

c is y intercept

If there was no sandstorm then c is 0

So the equation is

Step-by-step explanation:

so for 5 I'm really sorry. I couldn't see if the exponent is 11 or not.

The correct answer is Point A' is located at (-5, -4).

When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).

Answer:

x=2 or x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x2−20x+50=18

Step 2: Subtract 18 from both sides.

2x2−20x+50−18=18−18

2x2−20x+32=0

Step 3: Factor left side of equation.

2(x−2)(x−8)=0

Step 4: Set factors equal to 0.

x−2=0 or x−8=0

x=2 or x=8

Answer:

1. x = 8

2. x = 2

Step-by-step explanation:

2 • (x - 5)2 -  18  = 0

2.1     Evaluate :  (x-5)2   =    x2-10x+25

3.1     Pull out like factors :

 2x2 - 20x + 32  =   2 • (x2 - 10x + 16)

3.2     Factoring  x2 - 10x + 16

The first term is,  x2  its coefficient is  1 .

The middle term is,  -10x  its coefficient is  -10 .

The last term, "the constant", is  +16

Step-1 : Multiply the coefficient of the first term by the constant   1 • 16 = 16

Step-2 : Find two factors of  16  whose sum equals the coefficient of the middle term, which is   -10 .

     -16    +    -1    =    -17

     -8    +    -2    =    -10    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -8  and  -2

                    x2 - 8x - 2x - 16

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-8)

             Add up the last 2 terms, pulling out common factors :

                   2 • (x-8)

Step-5 : Add up the four terms of step 4 :

                   (x-2)  •  (x-8)

            Which is the desired factorization

2 • (x - 2) • (x - 8)  = 0

4.1    A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

thank me later

The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.

With that being said, here is the order of the numbers from smallest to largest:

4.38

4.5

4.6

4.9

Answer:

Here are the numbers ordered from closest to zero to farthest from zero:

4.38 (closest to zero)

4.5

-4.6

-4.9 (farthest from zero)

Answer:

A, C

Step-by-step explanation:

If it is inversely proportional then y = k/x

Let's try one by one for the options. (im replacing y and x in the equation and finding k to see if k is the same all throughout)

A.

6 = k/1 (k=6)

3 = k/2 (k=6)

2 = k/3 (k=6)

1.5 = k/4 (k=6)

Yes! It's the same everywhere so this is correct!

B.

7.5 = k/2 (k=15)

5 = k/3 (k=15)

3 = k/5 (k=15)

2 = k/7 (k=14)

For the last one k is not the same so nope. It is wrong.

C.

24 = k/1 (k=24)

8 = k/3 (k=24)

k = 6×4 = 24

k = 24×1 = 24

This is correct too.

D.

k = 0.1×200 = 20

k = 0.3×40 = 12

k = 0.8 × 25 = 20

We can already see that k is not the same everywhere.

Only A and C, x and y are inversely proportional for all of the values
