Answer: The volume is 3560.76 in^3 or 1134π
Step-by-step explanation:
The formula for the volume of a cylinder is πr^2*h
so the radius is 9 and the height is 14 so we will put that into the formula and solve.
v=3.14 * 9^2 * 14
v= 3.14 * 81 *14
v = 3560.76 in^3 or 1134π

The box plots show Lauren’s chemistry scores and her biology scores. Chemistry 2 box plots. The number line goes from 50 to 100. For chemistry, the whiskers range from 55 to 90, and the box ranges from 60 to 85. A line divides the box at 80. For biology, the whiskers range from 50 to 90, and the box ranges from 60 to 80. A line divides the box at 70. Biology Lauren used the steps below to determine the differences in the medians and the interquartile ranges. Step 1 Find the median for chemistry: 80 Find the median for biology: 70 Step 2 Find the difference in the medians: 80 minus 70 = 10 Step 3 Find the interquartile range for chemistry: 85 minus 80 = 5 Find the interquartile range for biology: 80 minus 70 = 10 Step 4 Find the difference in the interquartile ranges: 10 minus 5 = 5 Lauren determined that the difference in the medians is greater than the difference in the interquartile ranges. Which explains Lauren’s error? Lauren made her first error in step 1 because the median is 85 for chemistry and 80 for biology. Lauren made her first error in step 1 because the median is 60 for chemistry and 60 for biology. Lauren made her first error in step 3 because she should have used 90 minus 55 = 35 for chemistry and 90 minus 50 = 40 for biology. Lauren made her first error in step 3 because she should have used 85 minus 60 = 25 for chemistry and 80 minus 60 = 20 for biology.
Answer:
Lauren made her first error in step 3 because she should have used 85 minus 60 = 25 for chemistry and 80 minus 60 = 20 for biology.
Step-by-step explanation:
Lauren's box plots may have looked like those below.
Step 1
Chemistry median = 80
Biology median = 70
Correct.
Step 2
Difference in medians = 80 - 70
Correct
Step 3
Chemistry IQR = 85 - 60 = 25
Biology IQR = 80 - 60 = 20
Wrong.
This is where Lauren made the mistake.
She was finding the difference between the Max and Q3.

Bella wants to know how tall the oak tree in her back yard is, so she picks
a point that is 75 feet away from the base of the tree. She measures the
angle of elevation to be 40° from this point to the top of the tree. To the
nearest tenth of a foot, how tall is
A-89.4 feet
B-62.9 ft
C-48.2 ft
D-57.5 ft
Answer:
B = 62.9ft
Step-by-step explanation:
The distance where she is from the oak tree is 75ft,
The angle of elevation the stone makes with the top of the oak tree is 40°
The height of the tree is x ft
See attached document for better illustration
Using SOHCAHTOA,
Tanθ = opposite/ adjacent
θ = 40°
Opposite = x ft
Adjacent = 75ft
Tan40 = x / 75
X = 75 × tan40
X = 75 × 0.8390
X = 62.92ft
The height of the oak tree is 62.9ft
Susan's car is 4 yards long. Alexa's car is 16 feet long. When you line them up one in front of the other, how long are they together. Answer in feet
Answer:
28 feet long together
Step-by-step explanation:
in 1 yard there is 3 feet so in 4 yards it would be 3(4) which is 12. add 12 to 16 and you get 28
Answer:
28 feet
Step-by-step explanation:
A yard is 3 feet, so
4 yards*3 feet=12 feet.
12 feet+16 feet=28 feet

Study the patterns and write down :
(a) Row 5
(b) Row n
(c) Row (n+1)
Answer:
a) Row 5: 75 - 216 - 51
b) 3n² - (n+1)³ - (71-4n)
c) 3(n+1)² - (n+2)³ - (67-4n)
Step-by-step explanation:
Column 3:
Arithmetic sequence with common difference: 63-67 = -4
an = 67 + (n-1)(-4)
an = 67 - 4n + 4
an = 71 - 4n
Row 5: 3×5² - (5+1)³ - (71-(5×4))
Row 5: 75 - 216 - 51
Row n: 3n² - (n+1)³ - (71-4n)
Row n+1: 3(n+1)² - (n+1+1)³ - 71-4(n+1)
Row n+1: 3(n+1)² - (n+2)³ - (67-4n)
Answer:
Column 1
Tn= 3n²
row n= 3n²
row n+1= 3(n+1)²
When n=5,
T₅ = 3(5)²
T₅ = 75
Thus, row 5= 75
Column 2
Tn= (n+1)³
row n= (n+1)³
row n+1
= (n+1+1)³
= (n+2)³
When n=5,
T₅ = (5+1)³
T₅ = 6³
T₅ = 216
row 5= 216
Column 3
Notice that the terms decrease by 4 with each row.
This means that there is a common difference of -4.
Common difference formula
Tn= a +d(n-1)
where a is the first term and d is the common difference.
Tn= 67 -4(n-1)
Now, simplify the formula
Tn= 67 -4n +4
Tn= 71 -4n
Row n= 71 -4n
Row n+1
= 71 -4(n+1)
= 71 -4n -4
= 67 -4n
when n=5,
T₅= 71 -4(5)
T₅= 51
Row 5= 51
Row n is the general formula for the pattern. To find the n+1 row, susbt. n+1 into n in the formula in row n.

nanette installed a security system in her office for $150. the monthly monitoring fee is $30. so far, nanette has spent $420 for her security system. for how many months has she had the service?
Answer:
9 months.
Step-by-step explanation:
Well we subtract the one time fee of $150 from $420
420-150=270
Now we need to divide $270 by $30, the price she pays every month.
270÷30=9
She has had the service for 9 months.

Answer:

Step-by-step explanation:
[tex]8^{0}[/tex] = 1, [tex]8^{\frac{1}{3} }[/tex] = [tex]\sqrt[3]{8}[/tex] = 2, [tex]8^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{8^2}[/tex] = 4, [tex]8^{1}[/tex] = 8
The series can be expressed in non exponent terms as
1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 ← 10 terms
There is a common ratio r between consecutive terms, that is
r = 2 ÷ 1 = 4 ÷ 2 = 8 ÷ 4 = .... = 2
This indicates the sequence is geometric with sum to n terms
[tex]S_{n}[/tex] = [tex]\frac{a(r^{n}-1) }{r-1}[/tex]
where a is the first term and r the common ratio
Here a = 1 and r = 2, thus
[tex]S_{10}[/tex] = [tex]\frac{1(2^{10}-1) }{2-1}[/tex] = 1024 - 1 = 1023

Each visit to a water park costs $19.95. An annual pass to the park costs $89.95. Write an inequality to represent the number of times you would need to visit the park for the pass to be a better deal. Use x for your variable. Do not use $ in the response PLS help
Answer: 19.95 x >89.95
Step-by-step explanation:
Hi, to answer this question we have to write an inequality using the information given:
The cost of each visit (x) is 19.95. That expression must be higher than the cost of the annual pass (89.95).
Mathematically speaking:
19.95 x >89.95

The volume of a sphere with a radius of 5 cm is approximately _[blank]_ cm3.
Enter the value that correctly fills in the blank in the previous sentence.
Use 3.14 for π, and round your answer to the nearest hundredths place if necessary.
Answer: The volume of a sphere with a radius of 5 cm is approximately 523.33 cm3.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere (V) = 4/3 π radius³
Replacing with the values given and solving for V (volume)
V = 4/3 (3.14) 5³ = 4/3 (3.14) 125= 523.33 cubic centimeters
The volume of a sphere with a radius of 5 cm is approximately 523.33 cm3.

Tyler simplified the expression x Superscript negative 3 Baseline y Superscript negative 9. His procedure is shown below.
x Superscript negative 3 Baseline y Superscript negative 9 = StartFraction 1 Over x cubed EndFraction times StartFraction 1 Over y Superscript negative 9 EndFraction = StartFraction 1 Over x cubed y Superscript negative 9 EndFraction
What is Tyler’s error?
Both powers should be in the numerator with positive exponents.
Both powers should be in the denominator with positive exponents.
The power x cubed should be in the numerator and the power y Superscript 9 in the denominator.
The power y Superscript 9 should be in the numerator and the power x cubed in the denominator.

What is the value of y
Answer: y=54
Step-by-step explanation: since a triangles angles =180 and you just have this equation 180-72=2y that equals 108=2y
Answer:
The answer is B. 54 degrees.
Step-by-step explanation:
A triangle must be 180 degrees when all three angles are added together. 180 minus 72 is 108 degrees, which you have to divide by two, because there are two y values.
You can check this by adding 72 plus 54 plus 54 to get 180 degrees total.
If x+y−z=8 and x−y+z=12, then x=
Answer:
x = 10
Step-by-step explanation:
We see and show that x = 10
This makes y = 5 and z = 7 as 5-7 (y-z) = -2
As y5-z7 = -2 then we add 10 = 8
x+y-z = 10x-2yz = 8
x-y+z = 10 -5 +7 = 12 we know x = 10
We cna now prove.
x+y-z =8
x+5y-7z = 8
x +-2yz = 8
x = 8+2yz
x= 10
And prove
(x-5y)+7z= 12
x-y =12-7z
x = 5+5y
x=10
as x-5 (=5+7z) = 12
