Answer:
144.51326 [tex]cm^{2}[/tex]
Step-by-step explanation:
A = 2πrh + 2π[tex]r^{2}[/tex]
d = 4
r = 4/2 = 2 cm
h = 9.5cm
A = 2π(2)(9.5) + 2π[tex](2)^{2}[/tex] = 144.51326 [tex]cm^{2}[/tex]

A floor mat for gymnastics is a square with a side length of 14m. What is the area of the floor mat in square metres? Explain?
Answer:
196 square meters
Step-by-step explanation:
If the floor mat is square and one side is 14m then all sides are 14m. Given this you would find area by multiplying length by width.
L=14 W=14
14x14=196
There are 196 square meters

North carolina has 12 less electoral votes than florida. Write and solve a subtraction equation if the total number of votes for both states is 64
Step-by-step explanation:
Given
North Carolina has 12 fewer electoral votes than Florida
The total number of votes is 64
Suppose Florida receives [tex]x[/tex] votes
thus, votes received by North Carolina is [tex]y[/tex]
So, we can write
[tex]\Rightarrow x-y=12\quad \ldots(i)[/tex]
[tex]\Rightarrow x+y=64\quad \ldots(ii)[/tex]
Solving the above equations we get
[tex]x=38,y=26[/tex]
To test the durability of cell phone screens, phones are dropped from a height of 1 meter until they break. A random sample of 40 phones was selected from each of two manufacturers. The phones in the samples were dropped until the screens broke. The difference in the mean number of drops was recorded and used to construct the 90 percent confidence interval (0.46,1.82)
to estimate the population difference in means.
Consider the sampling procedure taking place repeatedly. Each time samples are selected, the phones are dropped and the statistics are used to construct a 90 percent confidence interval for the difference in means. Which of the following statements is a correct interpretation of the interval?
Answer:
See below.
Step-by-step explanation:
I see there are no answer choices you've provided, but in order to interpret a confidence interval correctly, you might say something like "We are 90% confident that the true difference in the mean number of drops is contained within the interval".
What is the measure of ∠A, the exterior angle of the triangle shown below? F. M∠A = 92°, because 180 – (50 + 38) = 92. G. M∠A = 272°, because 180 – (50 + 38) = 92 and 92 + 180 = 272. H.M∠A=78°,because 50–38=12and90–12=78. J. M∠A = 88°, because 50 + 38 = 88.
Answer: A is 88
Step-by-step explanation:
Sum of all angles is 180 degree.
Let the third interior angle be x.
38+50+x=180
88+x=180
x= 92
A and X are in linear pair.
A+X=180
A+92=180
A=88

Luke sold 4 times as many books as Maurice. If Maurice had sold 18 more books, he would have tied Luke for first place. How many books did Luke sell?
Answer:
24
Step-by-step explanation:
I guessed and checked but 24 -18 is 6 and 6 times 4 is 24
M + 18 = 4M
18 = 4M - M
18 = 3M
M = 18/3 = 6
4M = 4(6) = 24 sold by Luke

A car with an initial cost of $33,000 is decreasing in value at a rate of 7% each year. Write the exponential decay function to determine when the value of the car will be $15,000 to the nearest year
Answer:
n= 11.65 years
Step-by-step explanation:
Giving the following information:
Present Value (PV)= $33,000
Future Value (FV)= $15,000
Decrease rate (d)= 7%
To calculate the number of years it will take to reach $15,000; we need to use the following formula:
n= ln(FV/PV) / ln(1+d)
n= ln(15,000/33,000) / ln(1.07)
n= 11.65 years

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using the equation, what height was the rocket launched from? y=-16x^2+57x+32
9514 1404 393
Answer:
32 feet
Step-by-step explanation:
0 seconds after launch, the rocket is still sitting on the tower. Its height is...
y = -16(0^2) +57(0) +32
y = 0 + 0 + 32 = 32
The rocket was launched from a tower 32 feet high.
During the 1990s, the forested area of Guatemala decrelised at an average rate of 1.7%.
If the forested area in Guatemala in 1990 was about 34 400 square kilometers, write an equation for the forested area for t years
after 1990. If this trend continues, predict the forested area in 2015.
Answer:
A is correct answer
Step-by-step explanation:
Here, we want to write an equation for a depreciation
The general form is;
V = I( 1 - r)^t
V is the present value in 2015
I is the initial value in 1990 which is 34,400
r is the decrease rate which is 1.7/100 = 0.017
t is the difference in years which is 2015-1990 = 25
Substituting these values, we have
V = 34,400(1-0.017)^25
V = 22,407.65 km^2

You choose two different movies on a list at random. Out of 10 movies on the list, 6 are action movies. The first movie you choose is an action movie. What is the probability that the second movie is also an action movie? Write your answer as a fraction in simplest form.
Answer:
5/9
Step-by-step explanation:
You have 10 movies in total. You take 1 out of 6 action movies. Now you have 5 action movies left, so that means the probability is 5/9. It's 5/9 because you chose 1 action movie out of 10 movies in total, so that means there are 9 movies in total left.

Answer:
3150 ft³Step-by-step explanation:
Since this is a rectangular prism, we need to do length × width × height to find the volume. Now despite the shape being tilted at an angle, nothing is different.
So we can see that the length is 25, the width is 18 and the height is 7
Rewrite the formula for volume replacing variables
25 × 18 × 7
Now solve.
25 × 18 = 450
450 × 7 = 3150
Now before we finalize our answer, there are two more things we need to do.
We need to add the measurement unit which is feet or ft
We also need to add ³ since it is volume
Add both of these to the end
3150 ft³ is your final answer

Solve for x. Round your answer to the nearest tenth.
Answer:
17.5
Step-by-step explanation:
[tex]15^{2}+9^{2}= 306\\[/tex]
[tex]\sqrt{306} = 17.5[/tex]
Answer:
x ≈ 17.5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² = 9² + 15² = 81 + 225 = 306 ( take the square root of both sides )
x = [tex]\sqrt{306}[/tex] ≈ 17.5 ( to the nearest tenth )

What is Pythagoras theorem?Pythagoras theorem says that in a right angle triangle, the square of the hypotenuse side is equal to the sum of the square of the other two legs of right angle triangle.
The image of the given problem is attached below. In this diagram, the radius of the circle is 1.5 meter long.
The triangle ABC shown in the graph is right angle triangle as, the tangent of the circle is perpendicular with the radius of it at the point of contact.
Thus, by the Pythagoras theorem,
[tex](AB)^2+(BC)^2=(AC)^2\\(1.5)^2+(x)^2=(1.5+1)^2\\(x)^2=(2.5)^2-(1.5)^2\\x=\sqrt{6.25-2.25}\\x=\sqrt{4}\\x=2\rm\; units[/tex]
Thus, considering the diagram below the value which represent the missing side, round to the nearest below, tenth, is 2 units.
