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

You can use the acronym PEMDAS to help you remember the Order of Operations in Maths.

Here's what it stands for:-

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

According to PEMDAS, the first operation is:-

Option A) 19-4

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

Answer:

B=9

Step-by-step explanation:

X=-3 Plus c = b

C= 27

|x plus b| also = c

B=27 divided by 3

Answer:

the answer to a is -27 the answer to d is 28 the answer to gis 15

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:

1000

Step-by-step explanation:

you have asked how many pupils have been surveyed and all of them have so it's 1000 the number of pupils

[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

If right pls give brainlest.

Step-by-step explanation:

Answer:

1.I think the dot plot was the right decision because we are trying to go over specific data.For instance bar graphs are good if you are trying to get data on things that are in ranges like 1-3 and 4-6 but when you have things like this where he is trying to show each value its better to use a dot plot

2. 16 students are in this class (you can just count the dots to get this answer)

3. the class is a adult swim class-yes,this class ranges between 18 year olds to 32 year olds which are all legally adults

Half the students are between 2 and 3 years old-no,the minimum or youngest age that this set has is 18 years old which is still alot of a higher value than 2 or 3

Step-by-step explanation:hope this makes sense and helps you

Answer:so they are questions that can be used with data and stiff so its the last one the specific brand in important

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

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

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:

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

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%
