Answers

Answer 1

Answer:

x = 16

Step-by-step explanation:

Given:

Number of students = 6Average mark = 15

Therefore, total marks = 15 × 6 = 90

To find the value of x, add up the individual marks:

12 + 16 + 14 + 13 + 19 + x = 74 + x

Now equate this to the total number of marks found previously:

74 + x = 90

Solve for x:

⇒ 74 + x - 74 = 90 - 74

⇒ x = 16

Therefore, the value of x is 16.

What is the solution to the equation 6 m = 60?
m = 10
m = 50
m = 66
m = 360

Answers

Answer:

[tex]\displaystyle m = 10[/tex]

Step-by-step explanation:

[tex]\displaystyle \frac{60}{6} = \frac{6m}{6} \\ \\ \boxed{10 = m}[/tex]

I am joyous to assist you at any time.

Answer:

[tex]\sf{m=10}[/tex]

Step-by-step explanation:

The value of m must be found from one side of the equation in order to solve this problem.

6m=60

First, divide by 6 from both sides.

[tex]\sf{6m=60}[/tex]

[tex]\sf{\dfrac{6m}{6}=\dfrac{60}{6} }[/tex]

Then, solve it.

[tex]\boxed{{\sf{m=10}}}[/tex]

Therefore, the correct answer is m=10.

39 faren height plus 33 plus an unknown number to equal 180

Answers

Answer:

108

Step-by-step explanation:

39 + 33 + x = 180

To find the missing angle, we have to add together the two angles that are given and then subtract that from 180.

39 + 33 = 72

180 - 72 = 108

Therefore, our answer is 108 degrees.

Define a polynomial that is a difference of squares. How do you know that it is the difference of squares? How is it factored?

Answers

Answer:

When an expression can be viewed as the difference of two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5). This method is based on the pattern (a+b)(a-b)=a²-b², which can be verified by expanding the parentheses in (a+b)(a-b).

Step-by-step explanation:

Rebecca is calculating her expected expenses for her week long trip to Thailand. Her plane ticket costs 22,885 baht, her lodging costs 15,307 baht, and she has set aside 29,071 baht for food and spending money. What is Rebecca’s total expense? a. 128,071 baht b. 67,263 baht c. 21,493 baht d. 9,121 baht.

Answers

Answer:

The answer is B because you add up the 3 expenses

Step-by-step explanation:

Add the three expenses

The total expected expense of Rebecca for her week long trip to Thailand is given by: Option B: 67,263 baht

How to calculate total expense?

Total expense shows the overall expense for the thing we're expending for. We add all the expenses to get the total expense.

For this case, we're given that:

Cost of plane tickets = 22,885 bahtCost of lodging = 15,307Cost for food and other expenses = 29,071

So, total expected expense is sum of all these expenses.

Total expected expense = 22885 + 15307 + 29071 = 67263 baht

Thus, the total expected expense of Rebecca for her week long trip to Thailand is given by: Option B: 67,263 baht

Find the volume of a pyramid with a square base, where the side length of the base is 16.6m and the height of the pyramid is 9.1 m. Round your answer to the nearest tenth of a cubic meter.

Answers

Answer:

Formula for volume of square pyramid:-

V = 1/3 x a^2 x h

Where 'a' is the length of one side of the base, and 'h' is the height.

Plug in our values, given that:

16.6m = side length of base.

9.1m = height of pyramid.

V = 1/3 x a^2 x h

V = 1/3 x 16.6^2 x 9.1

V = 1/3 x 275.56 x 9.1

V = 1/3 x 2507.596

V = 2507.596/3

V = 835.865, which rounds to 835.9 cubic meters.

Solving systems by equations

Answers

Answer: x = 5, y = 7

Step-by-step explanation:

1. First, put the variables together/rearrange:

y - x = 2 & 5x - 4y = -3

2. Cancel out variable x by multiply the first equation by 5:

5y - 5x = 10 & 5x - 4y = -3

3. Add equations:

y = 7

4. Then determine x by plugging y back into the first equation y = x + 2:

x = 5

Can the GCF of a pair of numbers ever equal one of the numbers? Explain how you know

Answers

Answer:

It can

Step-by-step explanation:

For example, the GCF of 44 and 22 is 22.

Yes. If one number which is small is the factor of other number, then the GCF will be the smaller number
Eg: 13, 26
13 is the factor of 26. 26= 13*2
So, GCF of 13 and 26 = 13
