One cubic centimeter will hold 1 milliliter of water. How many milliliters will the aquarium hold? How many liters will it hold? LOADING... Click the icon to see the metric units of capacity. 40 cm 30 cm 50 cm The aquarium will hold nothing mL of water.
Answer:
The aquarium hold 60000 ml and in liters is 60 liters
Step-by-step explanation:
Length of aquarium = 40 cm
Breadth of aquarium = 30 cm
Height of aquarium = 50 cm
Volume of tank =[tex]Length \times Breadth \times Height[/tex]
Volume of tank = [tex]40 \times 30 \times 50[/tex]
Volume of tank =[tex]60000 cm^3[/tex]
Now , 1 cubic cm = 1 ml
60000 cubic cm = 60000 ml
Now 1000 ml = 1 l
60000 ml = [tex]\frac{60000}{1000}=60 liters[/tex]
So, the aquarium hold 60000 ml and in liters is 60 liters
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]

A candy jar contains flavored jelly beans. There are 7 orange, 9 cherry, 3 lemon, 15 licorice, and 6 blueberry. Find the probability of choosing two cherry jelly beans in a row (the first jelly bean is not replaced). PLEASE HELP!!!
Answer: 0.046
Step-by-step explanation:
From the question,
orange jelly beans= 7
Cherry jelly beans =9
Lemon jelly beans = 3
Licorice jelly beans = 15
Blueberry jelly beans = 6
Total jelly beans = 40
The probability of choosing the first cherry jelly beans will be = 9/40
After the first one is chosen, there'll be 8 cherry jelly beans and total of 39 left. The probability of choosing the second one will be = 8/39
The probability of choosing two cherry jelly beans in a row will be:
= 9/40 × 8/39
= 72/1560
= 0.046

Step-by-step explanation:
The number of students who jog and have one sibling who jogs is 416.
The total number of students who have one sibling who jogs is 1823 + 416 = 2239.
So the probability that a student jogs if they have one sibling who jogs is 416/2239 = 0.186.
The number of students who jog and have two siblings who jog is 400.
The total number of students who have two siblings who jog is 1380 + 400 = 1780.
So the probability that a student jogs if they have two siblings who jog is 400/1780 = 0.225.
Therefore, a student is more likely to jog if they have two siblings who jog than one sibling who jogs.

A. subtract the bottom equation from the top equation
Step-by-step explanation:
The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

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

Answer:
a) Find attached the completed Venn diagram (2nd diagram)
b) 25
c) 46
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

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.

solve. Eight less than 7 times a number is 6. Find the number.
The word "less than" switches the order around.
So instead of 8 - 7n = 6, our equation is 7n - 8 = 6.
Solving from here, we add 8 to both sides to get 7n = 14.
Now divide both sides by 7 to get n = 2.
Answer:
The number is 2

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

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.
