Answer:
r = 8
Step-by-step explanation:
V = π r^2 h so 383 = r^2 (6)
383 / 6 = r^2
64 = r^2 so
r = 8
A 20-foot piece of wire is attached from the top of a flagpole to a stake in the ground 7 feet from the base of the pole. Find the height of the flagpole.
Answer:
18.73 feets
Step-by-step explanation:
Given that:
Horizontal distance between ground and foot of flagpole = 7 feets
Lenght of wire = 20 feets
The height of the flagpole, h can be obtained using Pythagoras :
Adjacent = sqrt( hypotenus² - opposite²)
Height of flagpole = sqrt((length of wire)² - (horizontal distance between ground and flagpole)²)
Let height of flagpole = h
h = sqrt(20² - 7²)
h = sqrt(400 - 49)
h = sqrt(351)
h = 18.73 feets
On the first january 2014 carol invested some money in a bank account the account payes 2.5% compound interest per year on 1st jan 2015 carol withdrew £1000 from the account on 1st jan 2026 sge had £23517.60 in the account work out how much carol originally invested in the account
Answer:
$23,360
Step-by-step explanation:
Calculation to determine how much carol originally invested in the account
First step is to divide £23517.60 by 1.025
= (23,517.60)/(1+.025)
= (23,517.60)/1.025
=$22,944
Second step is to add back the $1,000 withdrew
=$22,944+$1,000
=$23,944
Now let calculate how much carol originally invested in the account
$23,944=1.025P
Divide both side by 1.025
P=$23,944/1.025
P=$23,360
Therefore the amount that carol originally invested in the account is $23,360

4(m-9)=2(2m+1)-40
What is the answer
Answer: i think that's right if not than t don't have a solution
Step-by-step explanation:4(m−9)=2(2m+1)−40
(4)(m)+(4)(−9)=(2)(2m)+(2)(1)+−40(Distribute)
4m+−36=4m+2+−40
4m−36=(4m)+(2+−40)(Combine Like Terms)
4m−36=4m+−38
4m−36=4m−38
Step 2: Subtract 4m from both sides.
4m−36−4m=4m−38−4m
−36=−38
Step 3: Add 36 to both sides.
−36+36=−38+36
0=−2

You are preparing for a breaktast party and need enough milk
for 20 people. Each person will drink about 200 mL of milk
Which is the best estimate of the amount of milk you
should
prepare: 400 mL or 4 L? Why?
 please help me i have this due super soon
Answer: 4 L
Step-by-step explanation:
20 × 200 = 4000 mL in total, or 4 L
So, the best estimate is 4 L.
Round each fraction to the nearest half and find the estimate. 2/6 + 1/6 one half 1 one and one half 2
Answer:
one half
Step-by-step explanation:
Given the expression
2/6 + 1/6
Find the LCM
[tex]= \dfrac{2+1}{6} \\= \dfrac{3}{6} \\= \dfrac{3*1}{3*2}\\= \dfrac{3}{3} * \dfrac{1}{2} \\= 1 * \dfrac{1}{2}\\= \dfrac{1}{2}[/tex]
Hence the required result is one half

A teacher surveys a sample of students from Lake Middle School. He asks the students where they’d like to go for a field trip. He records these results:
80 choose the aquarium.
60 choose the science center.
30 choose the planetarium.
40 choose the farm.
The teacher wants to figure out the relative frequency of a student choosing the aquarium. He will then estimate how many students out of all 1000 at the school are likely to choose the aquarium.
Answer the questions to solve the problem.
3. Suppose the teacher surveys one student at random. Based on the survey results, what is the estimated probability that the student chooses the aquarium?

Can someone help me please!!?? Eleven and seven-hundredths added to four and twenty-five hundredth the sum is
Answer:
[tex]15.32[/tex]
Step-by-step explanation:
Eleven and seven-hundredths [tex]=11+\frac{7}{100}[/tex]
(Here, [tex]\frac{1}{100}[/tex] denotes the hundredth)
Four and twenty-five hundredth [tex]=4+\frac{25}{100}[/tex]
Therefore,
Sum of Eleven and seven-hundredths added to four and twenty-five hundredth = [tex]11+\frac{7}{100}+4+\frac{25}{100}[/tex]
[tex]=15+\frac{32}{100}[/tex]
[tex]=15+0.32[/tex]
[tex]=15.32[/tex]

Find the value of x. Show your work of a piece of paper
Answer:
3
Step-by-step explanation:
x/1= 9/3
solve to get 3
Answer:
X = 3
Step-by-step explanation:
1. Find the difference between 1 and 3. The larger triangle is being multiplied by 3
2. To find x you must divide 9 by 3 since the bigger triangle is 3 times bigger then the smaller one. X then equals 3

Luna mixes 3/4 cup of orange juice with 3/8 cup of cranberry juice. She gives 5/8 cup of the juice to mags. How much is left in lunas glass
Answer:
1/2
Step-by-step explanation:
3/4+3/8=9/8
9/8-5/8=1/2
Answer:
1/2 is left in Luna's glass
Step-by-step explanation:
3/4 is the same as 6/8
So 6/8 + 3/8 = 9/8
9/8 - 5/8 = 4/8.
4/8 can be simplified to 2/4, which can be simplified to 1/2

growth or decay
Answer:
Growth
Step-by-step explanation:
You can simply look at this and say that this is growth because the number in the parenthesis is greater than 1.00.
It would only be decay if the parenthesis^2 resulted in a number less than 1
