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:

if no adult ones went, 30 students could go.

Step-by-step explanation:

If the cost of the student was 8, and there were 30 students going theoretically, this would be the most logical answer, since 8 multiplied by 30 is exactly 240

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:

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:

72 dollars

Step-by-step explanation:

all you do is multiply

Answer:

yes I can help you with this work

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

8 cups + 8 cups (due to 2 bottles of 64 oz)

16 cups+ 20 cups

36 cups

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:

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:

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

Let's use j to represent Jiri's age.

If Pamela is 6 years younger that Jiri, her age can be represented by j - 6.

Since the sum of their ages is 64, we can setup the equation j + (j - 6) = 64.

Simplifying on the left, we have 2j - 6 = 64.

Adding 6 to both sides, we have 2j = 70.

Dividing both sides by 2, we have j = 35.

So Jiri is 35 years old and Pamela is 6 years younger or 29 years old.

I think it is none of the above, I am not sure though.
