Answer:
1. 27 liters
2. 125.8%
3. 3 years
4. 0.98%
5. 9.6 years
Step-by-step explanation:
1. (60%)(45) = 27 liters
2. Percentage of weight relative to ideal weight = (100%)(78/62) = 125.8%, rounded to nearest 10th of a percent.
3. (20%)(15) = 3 years
4. Assume that the beginning height is 2552 meters and the height increases 25 meters. Then, the percentage increase = (100%)(25/2552) = 0.98%, rounded to the nearest 100th of a percent.
5. Beni's age = (40%)(24) = 9.6 years

You’ve decided to open a checking account. You know there are a number of differences with individual banking institutions. Name at least 3 good questions to ask to get started, and explain why knowing this information is helpful. Use complete sentences.
Answer:
1. Can I use the Atm for free?
2. What happens if I withdraw more money than I have in my account?
3. Does my account pay me intrest?
Step-by-step explanation:
1.ATMs allow you to withdraw money from your checking account without visiting a bank branch. But some withdrawals could cost you. Many banks charge you to use machines operated by other banks or third parties, and those fees can add up quickly.
2. Withdrawing more than your account contains is called an overdraft. Bank overdraft services generally allow your transaction to go through, but you will be charged a fee. Some banks prevent you from overdrafting when swiping your debit card and may let you request that all transactions are declined when your account doesn’t contain enough funds.
3. Generally, if checking accounts pay interest, the rate is very low. High-yield checking accounts offer higher interest but typically require higher balances. Savings accounts offer higher rates, but because the accounts are intended for saving, they’re subject to different rules
The figure shows a block of stone measures 8 cm by 5 cm by 2 cm and has a density of 2.5 g/cm3
what is the volume of the stone?
what is the mass of the stone?
Step-by-step explanation:
The volume of the stone = 8 × 5 × 2 = 80
Using density = mass / volume
So 2.5 = mass / 80
2.5 × 80 = mass
200 = mass
please give me brainliest answer
volume:
(8cm×5cm×2cm)=80cm³
I don't know the mass , sorry
According to the graph, what is the value of the constant in the equation below?
Answer:
0.8
Step-by-step explanation:
just use guess and check. Divide each of the constants by the width of one point. When you find a constant that matches, try that out with all the other widths, if it works with the other widths, then you found the right constant!
ayo please help me out
Answer:
-2/3x+4
Step-by-step explanation:
the reason is that if we take 2 point from the graph for example;
0,4 and 6,0
1) to get the gradient it is y2-y1/x2-x1
sub 0,4 and 6,0 into the equation from 1
4-0/0-6 which is 4/-6
4/-6 = 2/-3 and +4 because as seen in the graph it's hits the y-axis at +4
so it is 2/-3x + 4

Shannon swam 100 meters in 56.24 seconds. Rick swam 100 meters
in 59.48 seconds. Rick took how many seconds longer to swim
100 meters than Shannon?
I’m kinda in a rush anyone mind helping?
Answer:
find the difference between the two times by subtracting them;
59.48-56.24= 3.24 seconds
Step-by-step explanation:
Solve:
x + y = 7
3x - 2y = 11
By using Substituting method.
[tex]\large\underline{\sf{Solution-}}[/tex]
[tex]\sf \longmapsto x + y = 7 \: \: - - - (i)[/tex]
[tex]\sf \longmapsto 3x - 2y = 11 \: \: - - - (ii)[/tex]
By first equation,
[tex]\sf \longmapsto x + y = 7[/tex]
[tex]\sf \longmapsto x = 7 - y[/tex]
Now, we can find the original value of y.
[tex]\sf \longmapsto 3x - 2y = 11[/tex]
[tex]\sf \longmapsto 3(7 - y) - 2y = 11[/tex]
[tex]\sf \longmapsto 21 - 3y - 2y = 11[/tex]
[tex]\sf \longmapsto 21 - 5y = 11[/tex]
[tex]\sf \longmapsto - 5y = 11 - 21[/tex]
[tex]\sf \longmapsto - 5y = - 10[/tex]
[tex]\sf \longmapsto y = \dfrac{ - 10}{ - 5} [/tex]
[tex]\sf \longmapsto y = 2[/tex]
Now, we can find the original value of x.
[tex]\sf \longmapsto x + y = 7[/tex]
[tex]\sf \longmapsto x + 2 = 7[/tex]
[tex]\sf \longmapsto x = 7 - 2[/tex]
[tex]\sf \longmapsto x = 5[/tex]
Therefore, the values of x and y are 5 and 2 respectively.

Evaluate 1/2(x divided by 4)+y when x = 16 and y = 2/5 A. 4/5, B. 19/10, C. 12/5, D. 32/5
The expression 1/2(x divided by 4)+y when evaluated for x = 16 and y = 2/5 is 12/5
How to evaluate the expressionThe mathematical statement of the expression is given as
1/2(x divided by 4)+y
When the above expression is expressed using proper mathematical operators
We have the followng expression
1/2(x/4) + y
From the question, we have the followng values
x = 16 and y = 2/5
This means that
1/2(x/4) + y = 1/2(16/4) + 2/5
When evaluated, we have
1/2(x/4) + y = 12/5 or 2.4
Hence, the value of the expression si 12/5

a man is 3 times as old as his son. the sum of their ages is 48 years, how old is the son?
Let the sons age = x
The dads age would be 3x ( 3 times the sons age)
X + 3x = 48
Simplify:
4x = 48
Divide both sides by 4
X = 12
The sons age is 12
