Please help! I would be really grateful-this is due tonight! Please answer ASAP

Answer:

9²

Step-by-step explanation:

9 · 9 = 81

9² = 9 ·9

The expression  9X9 as a power is 9².

A number system is defined as a system of writing to express numbers.

We have to write 9X9 as a power.

Nine cross nine as power.

We know that nine is multiplied with nine we get eight one.

9×9=81

Here we used the operation multiplication.

Multiplication is a method of finding the product of two or more numbers

When two number with same base are multiplied then the powers will be added.

9×9

9¹⁺¹=9²

Hence, the expression  9X9 as a power is 9².

Answer:

Rate of change is slope

To calculate slope its

y2 - y1 / x2- x1  = slope

Just choose 2 random sets from the table.

I’m gonna go with (0,-10) and (2,20)

Now calculate slope

20 - (-10) / 2 - 0

Solve.

30 / 2

30/2 = 15

Rate of change is 15

Answer:

4 1/8

Step-by-step explanation:

If you take 1 and multiply by 3, you get 3. Pretty simple. When you multiply 3/8 by 3, its also easy. You just multiply the top number. 3 times 3=9. So, you have 9/8. And when your top number is equal or greater than your bottom number its more than a whole. So, you have 1 1/8. Then you add the 1 to the 3, and you get 4, you have 1/8 left over, so your answer is 4 1/8

Answer:

  A.  25.6 ft

  B.  28.2 ft

Step-by-step explanation:

The triangle inequality tells you the length of any side of a triangle lies between the sum and difference of the lengths of the other two sides:

  43.7 -30.7 < ? < 43.7 +30.7

  13.0 < ? < 74.4

Only two answer choices fall within that range:

  25.6 ft, 28.2 ft

Answer:

slope is 1/4； y intercept is -2

Step-by-step explanation:

read your textbook carefully

you note that you are given two point the x-intercept and y-intercept:

(8,0) and (0,-2) respectively.

before doing exercise, you need to know what is the slope formula (read your book).

slope formula is the change in y over the change in x.

or you can perceive that slope mean when x move forward one unit, what is change in y( how many units the y move).

Answer:

Hi! You just have to take his salary as a unity (one) and substract the fractions you are given. For example; lets say you have a cake (one) and then you eat 1/8 of it. You would be left with  [tex]1-\frac{1}8}[/tex] of the original cake.

Step-by-step explanation:

Salary:     [tex]1[/tex]

Spent [tex]\frac{2}{5}[/tex] :     [tex]1-\frac{2}{5}[/tex]

Spent [tex]\frac{1}{4}[/tex]:      [tex]1-\frac{2}{5} -\frac{1}{4}[/tex]

Spent [tex]\frac{1}{8}[/tex]:      [tex]1-\frac{2}{5} -\frac{1}{4} -\frac{1}{8}[/tex]

REMAINING: [tex]1-\frac{2}{5} -\frac{1}{4} -\frac{1}{8}[/tex]

Operate using LCM:  [tex]\frac{40-16-10-5}{40} = \frac{9}{40}[/tex]

The answer is (d)

Answer:

About 76%.

Step-by-step explanation:

To find the average of numbers, you add all of the numbers together and divide the total by the number of numbers. In this case, your numbers would be 95 twice, 87 five times, 73 three times, 63 four times, and 40 once. The total number of numbers is 15, and the total of all of the exam scores if you add them up is 1136. Finally, you would divide 1136 by 15, which would be 75.7333333, which would be an average of about 76%.

Answer:

b

Step-by-step explanation:

the arc length is calculated as

arc = circumference (C) × fraction of circle , then

16 = C × [tex]\frac{45}{360}[/tex] = C × [tex]\frac{1}{8}[/tex] ( multiply both sides by 8 )

128 = C

circumference of circle is 128 cm

Answer: -15^2

Step-by-step explanation: It goes down by -225 every time so the exponent form would be -15^2. Just keep on subtracting 225 every number. Add 225 for the 0x only.

Answer:

b = 26

Step-by-step explanation:

As angles I and K are equal in the triangle, the sides opposing them should also be of the same length. Therefore, the value of b is equal to the side of the other side's measure, which is equal to 26.

Answer:

5 months

Step-by-step explanation:

Daniel's provider charges $60 for installation and $45.95 per month. Sydney's provider has free installation and charges $57.95 per month

Let x = number of months

Daniel = 60 + 45.95x

Sydney = 0 + 57.95x

Equate both equations

60 + 45.95x = 0 + 57.95x

Collect like terms

60 - 0 =57.95x - 45.95x

60 = 12x

Divide both sides by 12

x = 60 / 12

= 5

x = 5 months

Daniel and Sydney would have paid the same amount for high-speed Internet service after 5 months

Answer:

1) 7.069 cm^2

2) 12.567 cm^2

3) 19.635 cm^2

4) 3.142 yd^2

5) 38.485 yd^2

6) 50.266 yd^2

Step-by-step explanation:

This problem is a repetition of the formula Area = [tex]\pi[/tex]*[tex]radius^{2}[/tex]

You are given the diameter of each circle.  The radius is 1/2 of the diameter, so, for example circle 1 has a diameter of 3 cm which means the radius is 3/2 cm and the area is A = [tex]\pi * (3 cm /2)^{2}[/tex] = 7.069 cm^2

don't forget your units.  Either cm or yd squared

Answer:

612 quarts

Step-by-step explanation:

First, let's set up this situation into a proportion.

Now, let's simplify the proportion.

As you can see, we have to multiple one by thirty-six to get to thirty-six. Whatever we do the denominators, we have to do to the numerators. Thus, 17 multiplied by 36 is 612 quarts.

Answer:

612 quarts

Step-by-step explanation:

If 170 quarts of ice cream is made in 10 hours. Then, in 1 hour (170/10) = 17 quarts of ice cream are made.

Therefore, in 36 hours (17×36) = 612 quarts of ice cream are made

Answer:

Step-by-step explanation:

f(x) • g(x)

= [tex]\sqrt{x^2+12x+36}[/tex] × (x³ - 12)

= [tex]\sqrt{(x+6)^2}[/tex] × (x³ - 12)

= (x + 6)(x³ - 12)

= x(x³ - 12) + 6(x³ - 12) ← distribute parenthesis

= [tex]x^{4}[/tex] - 12x + 6x³ - 72

= [tex]x^{4}[/tex] + 6x³ - 12x - 72

Answer:

[tex]18+0.08B\geq 75[/tex]

Step-by-step explanation:

there is a flat fee of $18

there is an incremental fee of $0.08 per ball which can be shown as [tex]0.08B[/tex]

so the amount that Carolina will spend would be [tex]18+0.08B[/tex]

the promotion only applies if Carolina spends $75 or more. the greater than or equal to symbol is [tex]\geq[/tex]

so the inequality would be [tex]18+0.08B\geq 75[/tex]

however, we could simplify this to [tex]0.08B\geq 57[/tex] but it is not necessary

Answer:

27

Step-by-step explanation:

every 30 men = 9 men with beards

you have 30 3 times in 90 so you get 27

60÷2=30

18÷2=9

30 men normal = 9 men with beards

90÷30=3

3×9=27

Answer:

27 is correct

Step-by-step explanation:

18 out of the last 60 men who walked by had a beard.

based on the given condition formulate

[tex]\boxed{\frac{18}{60}=\frac{x}{90} }[/tex]

[tex]\boxed{60x=18(90)}[/tex]

[tex]\boxed{\frac{18~x~90}{60} }[/tex]

[tex]\boxed{x=27}[/tex]

60÷2=30

18÷2=9

30 men normal = 9 men with beards

90÷30=3

how many of the next 90 men who walk by

you have 30 × 3  = 90 so you get 27

3 × 9 = 27

Therefore the correct answer is 27
