512

The small 3 in front of 8 is the term, cubed. Cubed means to multiply the number behind it by itself 3 times. That lucky number is 8! Multiply 8 by itself 3 times.

[tex]8^3~or~ 8 * 8 * 8 = 512[/tex]

The problem is solved! Your answer is 512

How: The range is the difference between the smallest and highest numbers in a list or set. To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest. The answer gives you the range of the list.

Answer:

Since a gallon is equal to 16 cup we need to get the amount of cups to 16.

1 1/4 x 12.8 = 16 so 12.8 servings! please tell me if im wrong

Answer:

a - 30.5

b - 31

c - 31

d - 2

Step-by-step explanation:

Mean is average:

31,29,31,30,31,30,31,31,30,31,30,31

366/12

30.5

Median is the middle of the data points.

Line data points up in order from least to greatest.

29,30,30,30,30,31,31,31,31,31,31,31

12/2=6

Since there is an even amount data points the median is the mean of the two middle data points:

Middle data points: 31,31

31

Mode is the most common data point.

It would be 31.

Range is highest point subtracted by lowest point.

31-29=2

Answer:

0.66

Step-by-step explanation:

4.91 x 10^2

Calculate 10 to the power of 2 and get 100.

4.91×100

Multiply 4.91 and 100 to get 491.

491

7.47×10^2

Calculate 10 to the power of 2 and get 100.

7.47×100

Multiply 7.47 and 100 to get 747.

747

491 divided by 747=0.65729585006693440428380187416332

0.65729585006693440428380187416332 is rounded to 0.66

[tex]\dfrac 34(5a-16) - \dfrac 13(6a-3)\\\\=\dfrac{15a}4 - \dfrac{48}4 - 2a + 1\\\\=\dfrac{15a}4 -12-2a+1\\\\=\dfrac{15a}4 -2a -11\\\\=\dfrac{15a-8a-44}{4}\\\\=\dfrac{7a-44}4[/tex]

Answer:

1.75a - 11

Step-by-step explanation:

Remember your order of operations, first you want to start inside the parantheses. Nothing can be simplified there so move on to multiplication.

Distribute (mutiply) ¾ with (5a - 16) as well as -⅓ with (6a - 3) to get

3.75a - 12 - 2a + 1

Combine like terms, so 3.75 with -2a as well as -12 with 1.

1.75a - 11

Which you could also write as

⁷⁄₄a - 11 or 1¾a - 11

Answer:

The volume is 160

Step-by-step explanation:

Explanation: To find the volume of the rectangular prism you need to multiply 8x20. The reason is because there are 20 cubes in each row (i'm sorry if i'm not good at explaining math very well). The way I found the volume was to count the amount of cubes on the side and multiply it by how many rows there were on top. So that brings me to 160. The product of 8x20. (I hope this helps, math isn't my best subject)

Answer:

V = 160 cubic inches

Given that,

Length, width and height of prism are 8 inches, 4 inches and 5 inches

The formula for the volume of a rectangular prism is given by :

So, the volume of the prism is 160 cubic inches.

Answer:

1. 17/40, 0.425, 42.5%

2. 7/8, .875, 87.5%

Step-by-step explanation:

Add all of our balloons popped, which is 40. striped balloons popped is 17, so 17/40. which is 0.425 and 42.5%

for polka dots, it would be 7/8. 35/40 simplest form is 7/8 then we get .875, which is 87.5%

Answer:

X = 7 :)

Step-by-step explanation:

Pythagorean theoreem: A^2 + B^2 = C^2

Now lets solve!!

5^2 + 5^2 = C^2

25 + 25 = c^2

Now we add!

25 + 25 = 50

Now we have to find the square root!!

[tex]\sqrt{50}[/tex] = 7

Have a nice day!!

Please rate and mark brainliest!!!

Answer:

x = 7

Step-by-step explanation:

All you do is use the Pythagorean theorem. The Pythagorean theorem states that A² + B² = C². The diagonal side is opposite to the 90-degree angle which means it's "C²". To find C², you add the 5² + 5² together (A² and B²). That equals 50. So C² = 50. To get rid of the square, you put the square root symbol over C² and 50. [tex]\sqrt{C^{2} } =\sqrt{50}[/tex]; C = [tex]\sqrt{50}[/tex]. You can simplify [tex]\sqrt{50}[/tex] to [tex]5\sqrt{2}[/tex] (Basically you find a square root that goes perfectly into 50 which was 25 and 2. The 25 would be canceled to 5 and the 2 would turn into [tex]\sqrt{2[/tex]). 5√2 is equal to 7.07 (Approximately). So the answer is 7.

Answer:

a=3

Step-by-step explanation:

[tex]2a + 6 = 12[/tex]

[tex]2a+6-6=12-6[/tex] ( Subtract 6 from both sides)

[tex]2a=6[/tex] ( Simplify)

[tex]\cfrac{2a}{2}=\cfrac{6}{2}[/tex] (Divide both sides by 2)

[tex]a=3[/tex]

Answer:

2a+6=12

2a=12-6

a=6/2

a=3

Answer: Lets say BC and EF = Xcm. AC is clearly longer than BC so its greater than Xcm. If AC is longer than Xcm, and EF is Xcm, then AC is no doubt longer than EF.

Step-by-step explanation:

Answer: A is farther away from C

Step-by-step explanation:

If BC = EF, then AC has to be greater than EF. This is because A is farther away from B from C
