Answer 1

Answer:

8x to the power three to the power 12

Step-by-step explanation:

Answer 2
56x^13

(7x) times (2x^4)^3


let’s focus on the right side.

(2x^4)^3

We need to distribute the ^3 to the 2 and x^4.

(2^3) (x^4)^3

8 (x^4)^3

When an exponent has an exponent, you multiply them.

8 (x^12) ⬅️ we got this by multiplying 4 and 3.


(7x)(8x^12)

When you have multiply exponents, you add the numbers. 7x can also be written as 7x^1.

1+ 12= 13

Multiply 7 and 8.


56x^13

Which operation is Not used in the phrase "three times a number , decreased by 2 , divided by 6" ?

Answers

the answer is addition

Answer:

Step-by-step explanation:

Let the number be x

3 times a no. = 3x            (Multiplication)

Decreased by 2 = 3x-2   (Subtraction)

Divided by 6 = [tex]\frac{3x-2}{6}[/tex]          (Division)

So, here, addition is not used

The slope of the graph is 1/4 rise/run and this is the gradient (m) of the graph. Because the gradient/slope is positive it means it is increasing from left to right.

The equation of a line is y = mx + b

Where m is the gradient/slope in this case 1/4 and b is the y-intercept in this case zero.

Based on that information we substitute it into the formula y = mx + b to get
y = 1/4 x as the equation of the line.

Two angles are vertical angles. The measure of one angle is (3x) degrees. The measure of the other angle is 42 degrees. What is the value of x?

Answers

Answer:

x =14

Step-by-step explanation:

Vertical angles are equal.

This means that 3x = 42

Divide each side by 3

3x/3 = 42/3

x =14

Answer: x=46.

Step-by-step explanation:

Vertical angles are opposite of one another. A whole line is 180 degrees. You have to subtract 42 from 180 which gives you 138. Then you divide by 3. Then you get 46.

So your hole must be deeper by another 2 feet and 6 inches. (or by 30 inches)

Step-by-step explanation:

1 foot = 12 in

4 feet = 12×4 in

4 ft = 48 in  (how deep it should be)

Current depth: 1 foot + 6 in

1 ft = 12in

12in + 6in = 18in (the current depth of your hole)
48in (total) - 18in (current) =  30 in (remaining depth)

30 in = ?ft + ?in
1 foot = 12 in            2ft = 24in              3ft = 36in                4ft=48in

The closest number that is below 30 is 24
We have 24inch = 2ft
And we have 6 inches remaining (30in-24in=6in)

2ft + 6in or 30in remaining

A fair, 6-sided die is rolled 60 times. Predict how many times it will land on a number greater than 2.

60
40
20
two thirds

Answers

Answer: 40!

Please give brainliest.

Step-by-step explanation:

Let us first diagnose the problem.

There is a die with 6 sides.

Sides: 1,2,3,4,5,6

4 of the 6 sides are greater than 2.

Let us use the theoretical probability formula of
Number of favorable outcomes / Number of possible outcomes.

Favorable outcomes being 4 because there is 4 numbers greater than 2, which is favorable to the outcome we want

Possible outcomes being 6 because the die has 6 sides.

Now lets put this in a fraction:

[tex]\frac{4}{6}[/tex]

Lets multiply our fraction by 60, as we are rolling the die 60 times.

[tex]\frac{4}{6} (60) = 40[/tex]
We got 40! Which basically means 40%.

Miss Rivas and Mr. Seipel have homerooms with the same perimeter. Mr. Seipel's homeroom has a width that is 1 1/10 times the width of Miss Rivas' homeroom

Answers

Answer: Unknown

Step-by-step explanation:

Well, we know that Mr. Seipel's homeroom is 11/10 times the width of Miss Rivas' homeroom. Because 11/10 = 1.1, we can multiply Miss Rivas' homeroom width by 1.1 to get Mr. Seipel's homeroom width. We can also divide Mr. Seipel's homeroom width by 1.1 to get Miss Rivas' homeroom width. But, you didn't provide the question in your post.
