Area of the half circle. To get the area of the circle u do radius^2*pi. this will be 2^2*pi in this example. so 4pi. because its half u have to to divide it by 2, so 4pi/2 is 2pi.

Now 2pi + 6 is the anwser

Answer:

13.5 ft

Step-by-step explanation:

base = 18ft

To find the height, take 75% of 18

To do this, take the decimal form of 75% (which is 0.75) and multiply that by 18:

0.75 x 18 = 13.5

13.5 would be the height

O dreaptă (d) și punctele A,B și C în aceasta ordine stind ca AB=10cm; BC=14cm desemnați lungimea segmentului [AC]=? Vă rogg dau coroana!!!!la cine e corect

Answers

Answer:

Length of line AC = 24 cm

Step-by-step explanation:

Given:

Length of line AB = 10 cm

Length of line BC = 14 cm

Find:

Length of line AC

Computation:

We know that line AB and BC are two part of line AC

So,

AC = AB + BC

Length of line AC = Length of line AB + Length of line BC

Length of line AC = 10 + 14

Length of line AC = 24 cm

Add, simplify the answer and write it as a mixed number

Blake is cutting a piece of rope into fourths. if each piece is 16 inches long, what is the length of the entire rope?

Answers

Answer:

64inches.

Step-by-step explanation:

Let x represent the length of entire rope.

Division Equation:

\frac{x}{4}  = 16

\frac{x}{4} X 4 =16x4 (Multiply each side by 4)

x=64

Therefore, length of entire rope is 64 inch.

3. People with type O-negative blood are universal donors (any patient can
receive a transfusion of O-negative blood). Only about 6.6% of the American
population has O-negative blood. If 270 unrelated people give blood in a certain
week, how many of these people do we expect to be universal donors? (Hint:
Remember to convert percent numbers to decimals before multiplying.)
PLEASE HELP

Answers

Answer:

We expect 17.82, that is, approximately 18 people to be universal donors.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they are universal donors, or they are not. The probability of a person being an universal donor is independent of any other person. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Only about 6.6% of the American population has O-negative blood.

This means that [tex]p = 0.066[/tex]

If 270 unrelated people give blood in a certain week, how many of these people do we expect to be universal donors?

This is E(X) when [tex]n = 270[/tex]. So

[tex]E(X) = np = 270*0.066 = 17.82[/tex]

We expect 17.82, that is, approximately 18 people to be universal donors.

Jamie recorded the number of points she scored during her last 5 basketball games. She scored, 15, 25, 10, 2, and 8 points. What is the mean absolute deviation of the points she scored during the last five games?​

Answers

Answer:

6.4

Step-by-step explanation:

Given scores:

15, 25, 10, 2, and 8

Mean of the scores:

(15 + 25 + 10 + 2 + 8)/5 =  12

Absolute deviations:

|15 - 12|= 3|25 - 12|= 13|10 - 12| = 2 |2 - 12| = 10|8 - 12| = 4

Sum of absolute deviations:

3 + 13 + 2 + 10 + 4 = 32

Mean absolute deviation:

32/5 = 6.4

total no of game (n)=5

score =15, 25, 10, 2, and 8 points

mean= sum of score/no.of game

=(15+25+10+2+8)/5=60/5=12

absolute deviation of

15=\15-12\=3

25=\25-12\=13

10=\10-12\=2

2=\2-12\=10

8=\8-12\=4

mean absolute deviation=

(3+13+2+10+4)/5=3.6

is the mean absolute deviation of the points she scored during the last five games.

Answers

Answer:

His salary after t years will be:

Step-by-step explanation:

David just accepted a job at a new company where he will make an annual salary of $69000. David was told that for each year he stays with the company, he will be given a salary raise of $2500.

This means that after t years, his salary will be given by:

How much would David make as a salary after 4 years working for the company?

A positive angle less than 360 degrees that is coterminal with -5 degrees is

Answers

Answer:

[tex]\theta = 355[/tex]

Step-by-step explanation:

Given

Let the angle be [tex]\theta[/tex]

[tex]\theta < 360[/tex]

[tex]\theta[/tex] is co-terminal with -5

Required

Find [tex]\theta[/tex]

Start by dividing 5 by 360 (ignore the negative)

[tex]\frac{5}{360} = 0.0138[/tex]

The nearest integer greater than 0.0138 is 1.

This implies that if you were to draw for this problem, the circle you would draw to show -5 degrees would go around 1 time

So, [tex]\theta[/tex] is calculated as:

[tex]\theta = -5 + 1*360[/tex]

[tex]\theta = -5 +360[/tex]

[tex]\theta = 355[/tex]

how to solve 2x-4(x+3)= x-3

Answers

Answer: x=-3

Step-by-step explanation:

2x-4(x+3)=x-3

2x-4x-12=x-3

-2x-12=x-3.    add 12 to both sides

-2x=x+9.        subtract x from both sides

-3x=9.            Divide both sides by -3

x=-3

Answers

Answer:

Step-by-step explanation:

We know that ABD is 30 degrees. To find BC, we need to use sin.

Equation:

BC = 16*sin(30 degrees) I recommend using a calculator to find the sine if you don't know what it means and how to use it. Sine is basically the side length opposite of the angle over the hypotenuse of the right triangle.

BC = 16*0.5

Answers

Answer:

Step-by-step explanation:

it's another one of those similar triangles

it's easier to see this one.

t /c = u / b

where

t = 7x + 3

c = 27

u = 35

b = 21

plug in the knowns

7x + 3 / 27 = 35 / 21

7x + 3  = 27 ( 35 / 21 )

7x + 3 = 9 ( 35 / 7 )     ( divided by 3 )

7x  + 3  = 9 ( 5)     ( 7 into 35 =5 )

7x  + 3  = 45

7x = 45 - 3

7x = 42
