The volume of a cylinder is 72 pi ft and the radius is 6ft. What is the height?
Answer:
Height = 2
Step-by-step explanation:
If pi ≈ 3.14
[tex]72\pi = 226.08[/tex]
[tex]h = \frac{V}{\pi r^{2} }[/tex] =
[tex]h = \frac{226.08}{\pi *6^{2}}[/tex] =
[tex]h[/tex] = [tex]2[/tex]

The city is issuing bonds to raise money for a building project. You obtain a $1700 bond that pays 5% interest annually that matures in 9 years. How much interest will your earn?
Answer:
I=P0r
A=P0+I=P0+P0r=P0(1+r)
I is the interest
A is the end amount: principal plus interest
P0 is the principle (starting amount)
r is the interest rate (in decimal form. Example: 5%=0.05)

Suppose SAT Critical Reading scores are normally distributed with a mean of 501 and a standard deviation of 110. A university plans to admit students whose scores are in the top 30%. What is the minimum score required for admission
Answer:
The minimum score required for admission is 558.75.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Suppose SAT Critical Reading scores are normally distributed with a mean of 501 and a standard deviation of 110.
This means that [tex]\mu = 501, \sigma = 110[/tex]
A university plans to admit students whose scores are in the top 30%. What is the minimum score required for admission
This is the 100 - 30 = 70th percentile, which is X when Z has a pvalue of 0.7. So X when Z = 0.525. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.525 = \frac{X - 501}{110}[/tex]
[tex]X - 501 = 0.525*110[/tex]
[tex]X = 558.75[/tex]
The minimum score required for admission is 558.75.

You need to find the WPM (words per minute) of each person.
Andre - 208 divided by 4 = 52
Noah - 342 divided by 6 = 57
You now know that Andre types 52 words per minute and Noah types 57 words per minute.
Answer: Noah types faster because he types 57 words per minute while Andre types 52 words per minute.
Answer:Noah types faster.
Step-by-step explanation: For Andre ,You do 208 divide 4 which gives you 52.For Noah, you do 342 divide by 6 which gives you 57.And since Noah type more words which is 57 while Andre type 52, that means Noah types faster.
Hope it helps.
what is 5 + 9 = 2(4 − 7,5)
Answer:
5 + 9 = 2(4 - 7.5) = No
Step-by-step explanation:
Add: 5 + 9 = 14
Conversion a decimal number to a fraction: 7.5 = 75/
10
= 15/
2
a) Write down the decimal 7.5 divided by 1: 7.5 = 7.5/
1
b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
7.5/
1
= 75/
10
Note: 75/
10
is called a decimal fraction.
c) Simplify and reduce the fraction
75/

= 15 * 5/
2 * 5
= 15 * 5/
2 * 5
= 15/

Subtract: 4 - 7.5 = 4/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(1, 2) = 2. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 2 = 2. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - four minus fifteen halfs = minus seven halfs.
Multiple: 2 * the result of step No. 3 = 2 * (-7/
2
) = 2 · (-7)/
1 · 2
= -14/
2
= -7 · 2/
1 · 2
= -7
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-14, 2) = 2.
In words - two multiplied by minus seven halfs = minus seven.
Compare: the result of step No. 1 vs the result of step No. 4 = 14 vs (-7) = No

TRUE or FALSE: If the variable is by itself, then it is understood to have a 1
as its coefficient.
Answer:
True
Step-by-step explanation:
The same goes for denominators. If there is a whole number, decimal, or variable without a denominator, you can automatically say that the denominator is 1. Because a number multiplied or divided by 1 stays the same.

Solve by using elimination. Express your answer as an Ordered pair (-x +2y=3 3x-2y=7
Answer:
(5,4)
Step-by-step explanation:
-x+2y=3
3x-2y=7
Add the like terms( 2y and -2y)(-x and 3x)(3 and 7) together. Do this vertically. 2y and -2y cancel eachother out.
2x=10Divide both sides by 2
x=5To find y, substitute x in for y in one of the equations
-5+2y=3add 5 to both sides
2y=8Divide both sides by 2
y=4Check:

Please mark as Brainliest!!!Vera went to the local salon to get a haircut. The cost was $24. Vera tipped the hair stylist 18%. What was the total cost of haircut including the tip? Round to the nearest cent.
=========================================================
Work Shown:
18% = 18/100 = 0.18
18% of 24 = 0.18*24 = 4.32
The tip is $4.32
Adding this tip amount onto the original bill leads to 4.32+24 = 28.32
-------------
As a slight shortcut, we can use the multiplier 1.18 to get
1.18*24 = 28.32
This works because
1.18*24 = (1+0.18)*24 = 1*24 + 0.18*24 = 24 + 0.18*24
Notice the portion "24 + 0.18*24" can be found buried in the 1.18*24 expression. I applied the distributive property.
The multiplier 1.18 represents an increase of 18%
We can think of it as
100% + 18% = 1+0.18 = 1.18

Dr. Jensen, a pediatrician, has 3 annual
checkups and 1 sick visit scheduled next
Tuesday, which will fill a total of 167
minutes on her schedule. Next Wednesday,
she has 1 annual checkup and 1 sick visit
on the schedule, which should take 75
minutes. How much time is allotted for
each type of appointment?
minutes for an
minutes for a
The time allotted is
annual checkup and
sick visit
Answer:
The time allotted is 46 minutes for an annual checkup and 29 minutes for a sick visit
Step-by-step explanation:
System of Equations
It's required to write and solve a system of equations to model the situation of Dr. Jensen. Let's call the following variables:
x = time allotted for annual checkups
y = time allotted for sick visit
Dr. Jensen has 3 annual checkups and 1 sick visit for a total of 167 minutes on her schedule, thus:
3x + y = 167 [1]
It's also given she has 1 annual checkup and 1 sick visit on her schedule for a total of 75 minutes, thus:
x + y = 75 [2]
We'll solve the system formed by equations [1] and [2] using the elimination method.
Subtract [1] and [2]:
3x - x = 167 - 75
2x = 92
Divide by 2:
x = 46
Substitute in [2]:
46 + y = 75
Subtract 46:
y = 75 - 46 = 29
y = 29
The time allotted is 46 minutes for an annual checkup and 29 minutes for a sick visit
AC has a length of _______ units. DE has a length of_______ units.
Answer:
AC= 13 and DE= 24
Step-by-step explanation:
use tge pythegorous theorum
for AC
a^2+b^2=c^2
(5x5) +(12x12)=c
25+144=169
√169 =13
DE
use the same approach
a^2+b^3=c^2
a2 +10^2=26^2
a^2+100= 676
676- 100= 576
√576= 26
