Answer:

The formula for circumference is 2•pi•r when you do that, you get 125.6. But it is half a circle, so it is 62.8

Step-by-step explanation:

Answer:

C. [tex]\sqrt{89}[/tex] cm

Step-by-step explanation:

First, we can start out by stating that this is a right triangle, since it has a right angle, shown by the marker square in the corner of the triangle. The x part, is called the hypotenuse. When finding the value of the hypotenuse, we use a thing called the Pythagorean Theorem. This theorem is :

a^2 + b^2 = c^2

a is one side length, and b is the other. c is the hypotenuse. To find x, the hypotenuse, we simply plug in the values, and solve.

8^2 + 5^2 = c^2

64 + 25 = c^2

89 = c^2

To get c alone, we do the square root of 89.

[tex]\sqrt{89}[/tex] = c

9.43398113 = c

So, the answer is C. [tex]\sqrt{89}[/tex] cm

Answer:

I believe the answer is 1/3 times (x-7)

Step-by-step explanation:

(forgive me if im wrong)

The number of students whose height less than 69" = 19

Hence option first is correct,

According to the given tally chart,

We can see that,

Frequency for height 65" = 1

Frequency for height 66" = 1

Frequency for height 67" = 9

Frequency for height 68" = 8

Since we have to calculate the number of students having height less than 69"

Therefore, neglect the other frequencies.

Now sum up the above frequencies,

= 1 + 1 + 9 + 8

= 19

Hence,

There are 19 students having height less than 69".

Answer: Median = the number in the middle of a set of data

So first we order the data:

7.85, 8.50, 8.85, 9.25, 10.85, 11.50, 12.65, 22.50

Now there is no exact number in the middle so we must find the number in the middle of 9.25 and 10.85 which is 10.05

Thus 10.05 is the median

Answer:

c

Step-by-step explanation:

The correct answer is D. -2

An expression which defines the relationship between two variables (one independent and one dependent variable).

The independent variable is the variable being controlled in the problem, and the dependent variable is the variable that changes with the change of independent variable.

If the slope of the function is negative, that means the output value decreases as the input value increases is called a decreasing linear function.

Since the function is decreasing,

So, for the minimum value of x, there will be maximum value of y.

So, for the greatest value of y, the value of x will be -2 which is minimum of all the options.

Answer:

25.92

Step-by-step explanation:

The formula for the volume of a triangular prism is 1/2(b*h*l).  So, it would be 3.6 * 2.4 * 6 = 51.84. Then multiply by 1/2. 51.84 * 0.50 = 25.92 cubic cm.

ANSWER:

59.4

EXPLANATION:

2.4 x 3.6 x 1/2 = 4.32 x 2 =  8.64

3.6 x 6 = 21.6

2.4 x 6 = 14.4 x 2 = 28.8

Answer:

5%

Step-by-step explanation:

22.05-21=1.05

1.05/21=.05

.05*100=5%

The sales tax is 5% of listed price.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given, Luke went shopping for a new pair of pants.

The listed price of the pair of pants was $21.

But the price with tax came to $22.05.

The taxed amount

= $22.05 - $21

= $1.05

To find the percentage of taxed amount:

We use the percentage formula,

let m be the required percentage.

So,

1.05 = m x 21 /100

m = 1.05 x 100 / 21

m = 105 /21

m = 5%

Therefore, taxed amount is 5% of original price.

Answer:

60??

Step-by-step explanation:

so the measure of a full circle is 360, so if its a half circle it is 180, and its divided into 3 sections( the porblem is if there not even sections this is wrong, i cant tell if they are or not)  so you do 180 divided by 3 and your answer is 60. if there are uneven sections all you have to do it take your protractor and line up the stright line with the bottom line then see what small number is the line pointing too. Sorry if this dosent make sense i can try to clarifi if you dont get it.

Answer:

To factor out -1/3 out of the expression -1/3x - 8, first divide -8 by -1/3 to get 24. Now just put 24 in the place of -8 in the original expression. Your final answer should be -1/3(x + 24). Hope this helps and have a phenomenal day!

Step-by-step explanation:

The expression for the factor, 1/3 out of the 1/3x - 7/3 is 1/3 (x - 7).

A factor is a number which entirely divides another number.

Let 8 is a number, so there 2 and 4 are factors of it.

The given expression is,

1/3x - 7/3

To find the factor 1/3 out of the expression,

Take 1/3 out from the expression,

1/3 (x - 7)

The required expression is 1/3 (x - 7).

Check the picture below, on the left side.

since the triangle ABC is an isosceles with twin sides, if we drop a line bisecting the angle at the vertex A, we end up with a perpendicular line that cuts the "base" in two equal halves, so then

[tex]\textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b \qquad \begin{cases} c=\stackrel{hypotenuse}{50}\\ a=\stackrel{adjacent}{14}\\ b=opposite\\ \end{cases} \\\\\\ \sqrt{50^2 - 14^2}\implies \sqrt{2500 - 196}=b\implies \sqrt{2304}=b\implies 48=b[/tex]

as you can see in the picture in red, now let's find CD.

[tex]\stackrel{\textit{pythagorean theorem}}{\sqrt{52^2 - 48^2}=14}+CD\implies \sqrt{2704-2304}=14+CD \\\\\\ \sqrt{400}=14+CD \implies 20=14+CD\implies 6=CD[/tex]

Answer:

Step-by-step explanation:

CD= 6

Answer:

Each triangle has an area of 6 and the square in the middle has an area of 9.

6 times 4 is 24, plus 9 is 33. Therefore, your surface area is 33
