Hi, can someone help me pretty please?

Answer:

56.52

Step-by-step explanation:

1. multiply your r by 2

so 9*2= 18

2. multiply that by pi, which you substitute 3.14 in for

so 18*3.14=56.52

Radius ( r ) = 9 inches

Circumference of the Circle ?

Circumference of the Circle = 2πr

Putting the value of r in the formula -

[tex] = 2\pi r[/tex]

[tex] = 2 \times \frac{22}{7} \times 9[/tex]

[tex] = 56.5 \: inches[/tex]

[tex] \mathsf \pink {Hence, \: the \: circumference \: of \: the \: circle \: is \: 56.5 \: in.}[/tex]

Answer:

c = 18π    exact answer

c = 56.52   decimal approximation

Step-by-step explanation:

c = 2πr

c = 2π * 9

c = 18π    exact answer

Using 3.14 for π

c = 18 * 3.14

c = 56.52   decimal approximation

Step-by-step explanation:

2/5=0.4

60*0.4=24

Answer: s ≤ 60

Step-by-step explanation:

The common inequality signs include:

> which is greater than

< which is less than

= which is equal to

≥ which is greater than or equal to

≤ which is less than or equal to

Since the speed limit is 60 miles per hour, it simply means that the speed limit is less than or equal to 60 miles per hour. This will be:

s ≤ 60

The above means the speed is less than or equal to 60 miles per hour

Answer:

f(h)=15(8)+30

8 Hours per week

Step-by-step explanation:

$30 per week means she has a start of $30, so this will be a constant.

What we want to find is how much she needs to work to earn the remaining amount, $120.

To find that we need to divide $120/15, giving us 8.

She needs to work 8 hours per week. This gives us the function

x=15(8)+30

Answer:

She will have to work 8 total hours that week.

Answer:

D

Step-by-step explanation:

all answers are x = 0. If we put 0 instead of X.

y=0^4+3×0^3-2×0+7

y=0+0+0+7

y=7

Answer:

n + 3 = 7

Step-by-step explanation:

n + 3 = 7

4 + 3 = 7

Step-by-step explanation:

Integers are like whole numbers, but they can also be negative.

Some examples of integers are -1, 2, 5 etc.

The open circle means that this inequality is not inclusive.

If the circle was filled in the inequality would have been x[tex]\leq[/tex]2

Answer:

Perimeter [tex]\sqrt{26}+\sqrt{5}+\sqrt{10}+\sqrt{17}[/tex] units.  Area 12 square units.

Step-by-step explanation:

Perimeter: total distance around the figure.

Distance Formula:  the distance between points [tex]\left(x_1,y_1\right) \text{ and } \left(x_2,y_2\right)[/tex] is

[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

[tex]AB=\sqrt{(6-1)^2+(2-1)^2}=\sqrt{25+1}=\sqrt{26}[/tex]

[tex]BC=\sqrt{(5-6)^2+(4-2)^2}=\sqrt{1+4}=\sqrt{5}[/tex][tex]CD=\sqrt{(2-5)^2+(5-4)^2}=\sqrt{9+1}=\sqrt{10}[/tex][tex]DA=\sqrt{(1-2)^2+(1-5)^2}=\sqrt{1+16}=\sqrt{17}[/tex]

The perimeter is the sum of all those segment lengths.

One way to find the area of the figure is to surround it with a rectangle, insert some lines so that the areas you do not want can be found and subtracted from the rectangle's area.  (See attached image.)

The area of the large rectangle around the figure is 5 x 4 = 20 square units.

The triangles have areas 1/2 (base) (height):

A. (1/2)(1)(4) = 2 square units

B. (1/2)(3)(1) = 1.5 square units

D. (1/2)(1)(2) = 1 square unit

E. (1/2)(5)(1) = 2.5 square units

Square C.  (1)(1) = 1 square unit

Total of all the area you don't want to include:

2 + 1.5 + 1 + 2.5 + 1 = 8 square units

Subtract 8 from the surrounding rectangle's area of 20, and you get the area of the figure is 20 - 8 = 12 square units.

Answer:

8.66

Step-by-step explanation:

Answer:

28/3

Step-by-step explanation:

Dividing a fraction is the same as multiplying it by the reciprocal.

First, convert 4 and 2/3 to an improper fraction.

You get 14/3. Multiply that by the reciprocal of 1/2 (2/1) to get your answer.

14/3 * 2/1 = 28/3
