How much water can fill this cylinder with diameter of 3m and height of 8cm
Answer:
0.565 m^3 to the nearest thousandth.
Step-by-step explanation:
The volume of the cylinder = π r^2 h
Here the radius r = 1/2 diameter
= 1/2 * 3 = 1.5 m
8 cm = 0.08 m.
So the volume = π (1.5)^2 * 0.08
= 0.565 m^3 to the nearest thousandth.
Two cars leave the same parking lot, with one heading north and the other heading east. After several minutes, the eastbound car has traveled 12 kilometers. If the two cars are now a straight-line distance of 15 kilometers apart, how far has the northbound car traveled?
Answer 3 kilometers
15 kilometers total minus 12 kilometers of the east bound car leaves only 3 kilometers for the northbound car to travel.

What is the solution to this equation?
–5(s – 30) = –10
A. s = –4
B. s = 8
C. s = 28
D. s = 32
Answer:
s = 32
Step-by-step explanation:
–5(s – 30) = –10
Divide each side by -5
–5/ -5(s – 30) = –10/-5
s - 30 = 2
Add 30 to each side
s-30+30 = 2+30
s = 32
Answer:
D. s=32
Step-by-step explanation:
To solve the equation, we want to find out what s is. In order to do this, we have to get s by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
–5(s – 30) = –10
s-30 is being multiplied by -5. The opposite of multiplication is division. Divide both sides by -5.
–5(s – 30)/-5= –10/-5
s-30=-10/-5
s-30=2
30 is being subtracted from s. The opposite of subtraction is addition. Add 30 to both sides.
s-30+30=2+30
s=2+30
s=32
Let's check our solution. Substitute 32 in for s in the original equation. If our solution is correct, the left side of the equation should match the right side.
–5(s – 30) = –10
-5(32-30)=-10
-5(2)= -10
-10=-10
The statement above is true, so we know that s is equal to 32, and D is the correct answer.
Find the area of the circle use 3.14 for
Answer: 153.86 cm²
Step-by-step explanation: To find the area of the circle shown here, start with the formula for the area of a circle which is A = πr².
Notice that here, we're given the diameter instead of the radius.
Remember that the radius is equal to half of the diameter.
So the radius of this circle will be equal to half of 14 cm or 7 cm.
So plugging into the formula, we have (π)(7 cm)².
A common mistake is to plug 14 cm into the formula but remember
that we must plug in the radius and not the diameter.
Multiplying, (7 cm)² is equal to (7 cm)(7 cm) or 49 cm².
So we have 49π cm².
So the area of the circle shown here is 49π cm².
Now, remember that π is approximately equal to 22/7 or 3.14 so we
can estimate the area of the circle by plugging in 3.14 for π.
So we have (49)(3.14) which is equal to 153.86 cm².
So the area of the circle is approximately equal to 153.86 cm².

Step-by-step explanation:
We need to first find the total length of the side.
let remaining length be x
perimeter= 40cm
4 (s)=perimeter
4(7+x)=40
28+4x=40
4x=40-28=12
4x=12
x=12/4=3
total length= 7+3= 10cm
4+y= 10=
y=6
therefore, area of square= s*s= 10*10=100cm²
find areas of the two triangles (unshaded).
1/2*3*10= 15cm²
1/2*6*10= 30 cm²
15/100*100= 15%
30/100*100= 30%
shaded percentage= 100-(15+30)
= 100-45
= 55%
which of the following is a geometric sequence?
The key thing to look for to determine whether a sequence is geometric is to see whether the ratio between consecutive terms - the number I would multiply one term by to get the next - is constant.
By inspection, we see that the fourth answer choice satisfies that, as [tex]\frac{81}{27}=\frac{27}{9}=\frac{9}{3}=\frac{3}{1}=3.[/tex] Why not the first? We have [tex]2=\frac{12}{6}\ne\frac{6}{2}=3.[/tex]
The third choice is not a geometric sequence, but rather an arithmetic sequence, where the difference between consecutive terms is constant. Just to make sure that it isn't geometric, we compute [tex]\frac{14}{9}\ne\frac{9}{4}.[/tex]
The second sequence is not geometric (although it does eventually converge to 1, but not its corresponding series), as [tex]\frac{4}{3}=\frac{2/3}{1/2}\ne\frac{3/4}{2/3}=\frac{9}{8}.[/tex]

The highest and lowest scores on a test taken by 80 students are within 19 points of the average of the exam. The average for this exam was 72. Set up an equation to solve for the highest and lowest scores. Show your original equation and the process used to find the highest and lowest exam score.
Answer:
The highest score is 91 and the lowest score is 53
Step-by-step explanation:
The highest and lowest scores on a test taken by 80 students are within 19 points of the average of the exam. The average is 72.
1. The method used to solve this question, is the use of absolute values.
2. Let x be the value that we can use to represent the lowest and highest scores. The equation using absolute values is given as:
| x - 72 | = 19.
Therefore:
x - 72 = 19 (highest score) or
- (x - 72) = 19 (lowest score)
3. We have to find the value of x for which it is the highest or lowest score.
The highest score is given as:
x - 72 = 19
x = 19 + 72
x = 91
For lowest score:
-(x - 72) = 19
-x + 72 = 19
x = 72 - 19
x = 53
The highest score is 91 and the lowest score is 53

1) An $1,000 investment is made in a trust fund at an annual percentage rate of 12%, compounded monthly. How long will it take the investment to reach $2,000?
2)If a $100 deposit is made at a bank that pays 12% per year, compounded annually, determine how long it will take for the investment to reach $2000.
3)Kelly invests $5000 with a bank. The value of her investment can be determined using the formula Y=5000(1.06)^t, where y is the value of the investment at time t, in years. Approximately how many years will it take for Kelly's investment to reach $20,000?
4)$2000 is invested at 5% per year, compounded semi-annually. How long will it take for the investment to triple in value?
Answer:
33 years, 7 months
Step-by-step explanation:
Using the compound interest formula Accrued Amount = P (1 + r/n)^(nt)
where Accrued amount (A) is the expected future balance
A = $8000
P = principal; $5000
r = 1.4% = 0.014
t = number of years
n = number of times interest is compounded = 12 for monthly
Therefore
8000 = 5000 (1 + 0.014/12)^(12t)
Therefore
(1.001167)^12t = 8000/5000
(1.001167)^12t = 1.6
finding the log of both sides
12t x log 1.001167 = log 1.6
12t = log 1.6 / log 1.001167
12t = 402.98
t = 402.98/12
t = 33.58
hence time to increase the balance is 33 years, 7 months

A related Question found at brainly (ID 16765143):
A group of 80 students in a college are surveyed. They are asked which of Spanish or French they are studying. 71 of the students surveyed studies at least one of the two languages.
a) Complete the Venn diagram.
b) How many students study only french?
c) How many students study Spanish?
Step-by-step explanation:
Find attached the Venn diagram (1st diagram)
a) Total number of students in college = 80
Since 71 out of the 80 students surveyed studies at least one of the two languages, the number of students that studied neither French nor Spanish = 80-71 = 9
From the venn diagram:
Number of students that study Spanish = 14
Number of students that study French = 25
We need to determine if the values are for Spanish only and French only respectively or for at least Spanish and French respectively.
Estimated value for the middle term = 80-(14+25+9) = 32
From the above calculation, the number of students that study both Spanish and French is 32 and it is more than each set value. This implies the value given in the Venn diagram is for Spanish only and French only respectively.
Let number of students that study both Spanish and French = x
Spanish only = 14
French only = 25
the number of students that studied neither French nor Spanish = 9
Total:
14 + 25 + x + 9 = 80
48 + x = 80
x = Number of students that study both Spanish and French = 32
b) French only = 25
c) Number of students that study Spanish = students that study at least Spanish
= 14+x = 14+32
Number of students that study Spanish = 46
