Answer:
area = 120√2 ft² or 169.71 ft²
Step-by-step explanation:
x² = 9² - 3² = 81 - 9 = 72
x = √72 = √(36 x 2) = 6√2 ft or 8.49 ft
area = 1/2(5 + 8)(6√2) = 120√2 ft² or 169.71 ft²
To find how high school students feel about hot lunches, Adam walks to the nearest high school and
gives a survey postcard to every twentieth student that enters the building. He asks the students to mail
the postcard in if they choose to participate in the study.
Why might the method used be biased?
Asking every twentieth student does not accurately represent the student population.
It is likely that student opinions in one particular high school do not accurately represent the opinions
of all high school students.
Students that take the time to complete the survey and mail it in probably feel strongly about hot
lunches.

Answer:
x-13
Step-by-step explanation:
why you may ask?
subtracted=being taken away from
13 is *being taken away from* x
so if using numbers, 13 is being taken away from 20
or 13 is being subtracted from 20 would be 7, so x-13 would be your expression

The perimeter of each semicircle can be found by using the equation 1/2 pi d (the place where I put the words pi has the pi symbol, and d is just a variable. Also use 3.14 as pi, and the top part is cut off a little bit, but it still counts as a full semi circle. Please help me.

Kay is using cone-shaped party hats as popcorn holders. The party hats have a diameter of 10 inches and a height of 9 inches. How many cubic inches of popcorn will they hold? Use 3.14 for pi. Round your answer to the nearest Cubic inch.
Answer:
B 236in³
Step-by-step explanation:
you use the equation
V=πr²h/3
π=PI r=Radius h=height
Sense in this problem they give you diameter instead of radius you want to divide it by 2 to get one half.
so the equation used looks like this:
3.14•5²•9/3=235.5
rounded up is 236in³

Answer: A 5
Step-by-step explanation:
20% * 25
= 0.2 * 25
= 5
She can expect to hit the bullseye 5 times.
Answer:
A. 5
Step-by-step explanation:
Regina throws 25 darts and hits the bullseye 20% of the time. So we would set up the equation as 0.20*25 (as we are looking for 20% of 25 and of means multiplication and 20% is 0.20). 0.20*5=5 so she can expect to hit the bullseye 5 times. Therefore, A is the correct answer choice.
What is the exact circumference of a circle that has a radius of 10 cm?
Answer:
C = 20π cm
Step-by-step explanation:
If you want the "exact circumference," use π instead of the usual approximation 3.14 or 3.14159.
Here the circumference is C = 2π(10 cm), or C = 20π cm.

If you count all of the dots, you see that the total amount of math books is 12.
Then, look at the column between 2 and 2 2/8. You see that there are 2 books that weigh 2 1/8 pounds.
Therefore, there are 2 out of the 12 books that weigh 2 1/8 pounds.
2/12 can also be simplified down to 1/6.

Answer:

To solve this problem, you should make sure to find the equation first. Start by doing rise/run with your two given points on the graph. From the point (-1,1) you rise 4 and then run 16 over to the point (3,2). That gives us a slope of 4/16 which can then be simplified to 1/4. That means that letter F tells us the equation of the line is y= 1/4x + 5/4.
From there you want to check your points, (3,2) and (-1,1). The first number is always x and the second number is always y. So you plug the point numbers into the equation we just found to see if they work. In the photos I inserted are how to do this step.
Once you have checked your points and you know for sure they're solutions, that gave you letters A and B. Since the point (1, 3/2) is also given in one of the answers we should check that point as well. (Also done in one of the photos) Since the point came out correctly that gives us letter C and also tells us there is more than 2 solutions. This means that letter E is also correct.
Hope this helped!

If f(x) = 42 - 5 and g(x) = 3x+ 7, which of the following statements are true?
I f(0) = g(-4)
II f(-2) - 9(2)
III f(0) = g(3)
IV f(6) - g(4)
Α. I only
B. I and IV only
C. II and III only
D. All are true
Answer:
B. I and IV only
Step-by-step explanation:
You replace the x with the numbers in the parenthesis. So for I it would be:
f(0) = 4(0) - 5 -> 0 - (-5) -> -5
g(-4) = 3(-4) +7 -> -12 + 7 -> -5
You solve each one and if your answer matches with each other, your answer is right.
If you did this with II and III, you wouldn't get the same answers.
For IV it would be:
f(6) = 4(6) - 5 -> 24 - 5 -> 19
g(4) = 3(4) + 7 -> 12 + 7 -> 19

Tell whether the angles are complementary or supplementary. Then find the value of x.
the angles are complementary because they add up to 90° because of the red square. x=20
Step-by-step explanation:
4x-5+15=90
4x+10=90 subtract 10 from each side
then you get left with 4x=80
divide 4 from each side then you get left with x=20 and to check just substitute 20 where x is so 4(20)-5= 80-5=75 +15=90.

Answer:
Length = 13 in
Width = 10 in
Step-by-step explanation:
Let L be the length.
Let W be te width.
From the question given above, the Lenght is 3 more that the width i.e
L = 3 + W
Next, we shall determine the width (W). This can be obtained as follow:
Length (L) = 3 + W
Width (W) = W
Area (A) = 130 in²
A = L × W
130 = (3 + W) × W
Clear bracket
130 = 3W + W²
Rearrange
W² + 3W – 130 = 0
Solving by formula method
W = –b ± √(b² – 4ac) / 2a
a = 1
b = 3
c = –130
W = –3 ± √(3² – 4 × 1 × –130) / 2 × 1
W = –3 ± √(9 + 520) / 2
W = –3 ± √(529) / 2
W = –3 ± 23 / 2
W = –3 + 23 / 2 or –3 – 23 / 2
W = 20/2 or –26/2
W = 10 or –13
Since measurement can not be negative, the width is 10 in.
Finally, we shall determine the length. This can be obtained as follow:
L = 3 + W
W = 10
L = 3 + 10
L = 13 in
SUMMARY
Length = 13 in
Width = 10 in

The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes:
Part A: Describe how you can use similar triangles to explain why the slope of the graph between points A and B is the same as the slope of the graph between points A and C.
Part B: What are the initial value and slope of the graph and what do they represent?
Step-by-step explanation:The slope of AB and BC are the same.
The initial value is 60 m and the slope is 40 m/min.
Step-by-step explanation:
The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes.
See the graph attached.
Part A : If we consider two right triangles one Δ ABD and Δ BCE, where D(2,100) and E(1,60) points.
Now, those two triangles are similar and hence the slope of line segment AB will be .
Again, the slope of the line segment BC will be
Hence, and the slope of AB and BC are the same. (Answer)
Part B : From the graph, it is clear that the initial value of the graph is 60 m and it represents that initial position of the shark i.e. at t = 0 min, the shark was at a depth of 60 m from the water surface.
The slope of the graph is 40 means the rate of change of distance from the Ocean surface of the shark with respect to time in minutes will be 40 m per min. (Answer)

Answer:
r= 16.65
Step-by-step explanation:
Formula of cone V= 1/3 pi r ^2 h
They give us the volume and height, we just need to find the radius.
85= 1/3 pi r^2 9
1/3 of 9 is 3.
85= 3 pi r^2
divide by 3 on both sides.
28.3= pi r^2
square both sides with calculator or logic and round to nearest tenth.
5.3= pi r
divide pi.
r= 5.3 pi = 16.65
To find volume, plug everything in the formula.
