Answer:
The height is 20 cm.
Step-by-step explanation:
First, we have to know that the volume formula is V = πr²h and the base area of cylinder is a circle. So we can let πr² be 77 cm² . Then we have to substitute the following values into the formula :
[tex]v = 1.54 \: l[/tex]
[tex]v = 1540 \: {cm}^{3} [/tex]
[tex]v = \pi \times {r}^{2} \times h[/tex]
Let πr² be 77,
Let v be 1540,
[tex]1540 = 77 \times h[/tex]
[tex]77h = 1540[/tex]
[tex]h = 1540 \div 77[/tex]
[tex]h = 20 \: cm[/tex]

Celia drank 2 3 liter of water Monday before going jogging. She drank 3 7 liter of water after her jog. How much water did Celia drink altogether? Write your answer as a mixed number.
Answer:
23/21 liters
Step-by-step explanation:
Celia drank
Before going jogging=2/3
After jogging=3/7
Total amount of water drank by Celia=2/3+3/7
L.C.M of the denominators 3 and 7 is 21
=14+9/21
=23/21
=1 2/21 liters
Answer: 23/21
Step-by-step explanation:
Litre of Water drank before jogging = 2/3
Litre of water drank after jogging = 3/7
The total amount of water drank altogether ;
2/3 + 3/7
The lowest common factor of 3 and 7 = 21
= (14 + 9)/21
= 23/21 litres
= 1 2/21 litres [1 whole number 2/21]
Multiply, then identify the coefficient of x in the product (x - 5)(x + 2). *
Answer:
-3 is the coefficient of x here
Step-by-step explanation:
The first thing to do here is to open the brackets.
(x-5)(x + 2) = x(x + 2)-5(x + 2)
x^2 + 2x -5x -10
x^2 -3x -10
When we say the coefficient of x, we mean the value by which x only is multiplied by in the equation. That would be -3
This must not be confused with the coefficient of x^2 which is entirely different from the coefficient of x

ONLY COMPLETE QUESTION 1
Answer: 1/4 full.
Step-by-step explanation:
The question is asking for how much gas will be left in the tank after 2/3 of the gas in the tank is used.
There is currently 3/4 of the tank remaining.
To find 2/3 of 3/4, you can multiply the fractions together.
Do this by multiplying both numerators and both denominators:
[tex]\frac{2}{3} *\frac{3}{4} = \frac{2*3}{3*4} = \frac{6}{12}[/tex]
Then, subtract 6/12 from 3/4. You can do this by simplifying the first fraction to 2/4 (divide both the numerator and denominator by 3).
3/4 - 2/4 = 1/4
There will be 1/4 of the tank left.
Answer:
1/4
Step-by-step explanation:
We have 3/4 of a tank
We will use 2/3 of the gas in the tank
See the diagram That will leave us 1/4
Mathmatically
3/4*2/3 = 2/4 =1/2 this is the amount that is used
Subtract this from the amount in the tank
3/4 -1/2
3/4 -2/4 = 1/4
This is the amount that is left in the tank
(PLEASE ANSWER ASAP I NEED IT IN A FEW MINUTES I WILL MARK BRAINLIEST) Jenna bakes pie at her bakery. She gets a 10 pound block of butter for $30.30. Each pound of butter is 2 cups. Each pie she makes requires 3/4 cup of butter. How many pies can she make? What is the cost of butter per pie?
Answer:
With that amount of butter she can make 26 pies.
For each pie she spends $1.13625 of butter.
Step-by-step explanation:
We first need to convert the total amount of butter she has from pounds to cups, to do that we need to multiply by 2, since for each pound she has 2 cups of butter, therefore:
butter in cups = 10*2 = 20 cups
Since each pie requires 3/4 cups of butter in order to calculate the number of pies she can make we need to divide the total amount of butter she has by the amount required for each pie. We have:
number of pies = total butter in cups / butter for one pie
number of pies = 20 / (3/4) = 20*(4/3) = 80/3 = 26.667
Since she can't make 0.66 pies, we will need to take only the integer part in consideration, therefore she can make 26 pies.
In order to know the cost for each pie we first need to know the cost for each pound of butter, to calculate that we take the total amount paid by her and divide it by the amount of butter she got.
price of butter per pound = 30.3/10 = 3.03
So each pound of butter costs $3.03 and is equivalent to 2 cups, we can make a rule of three to find the cost for each pie as shown below:
2 cups -> $3.03
3/4 cups -> $x
2/(3/4) = 3.03/x
2*(4/3) = 3.03/x
8/3 = 3.03/x
8x = 9.09
x = 9.09/8 = $1.13625
For each pie she spends $1.13625 of butter.

Rewrite the equation y=2|x−2|+4 as two linear functions f and g with restricted domains.
Answer:
f(x) = -2x + 8, x < 2
g(x) = 2x, x 》2
Step-by-step explanation:
|x - 2| is:
x - 2, for x 》2
-x + 2, for x < 2
For x < 2,
f(x) = 2(-x + 2) + 4
f(x) = -2x + 8
For x 》2,
g(x) = 2(x - 2) + 4
g(x) = 2x
The two linear functions for the given mode function y = 2|x - 2| + 4 will be y = -2x + 8 and y = 2x.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
As per the given mode function,
y = 2|x - 2| + 4
For x < 2 , |x - 2| = -(x - 2)
y = -2(x - 2) + 4
y = -2x + 4 + 4
y = -2x + 8
For x > 2, |x - 2| = x - 2
y = 2(x - 2) + 4
y = 2x - 4 + 4
y = 2x
Hence "The two linear functions for the given mode function y = 2|x - 2| + 4 will be y = -2x + 8 and y = 2x".

Eric is preparing for a regional swim meet that is a month away. He swims the same distance and clocks his best time on several different days. He plots the best time (in minutes) he swam each day as his y-variable and the day he swam it as his x-variable. When he plots his times and finds a line of best fit, he gets the equation y=−0.03x+3.45.
If Eric continues to practice, on the 15th day his best time for the day should be _[blank]_ minutes.
Enter the value that correctly fills in the blank, like this: 42
Do not round your answer.
Answer:
On the 15th day his best time for the day is 3 minutes.Step-by-step explanation:
The line that best fits is
[tex]y=-0.03x+3.45[/tex]
Where [tex]x[/tex] is days and [tex]y[/tex] is time in minutes. So, we have [tex]x=15[/tex], replacing this in the equation and solving for [tex]y[/tex], we have
[tex]y=-0.03(15)+3.45=-0.45+3.45=3[/tex]
Therefore, on the 15th day his best time for the day is 3 minutes.

Last question: What equation represents three less than five times a number is twelve?
A. 3 - 5x = 12
B. 5x - 3 = 12
C. 5(3 - x) = 12
D. 5(x - 3) = 12
Answer:
B, 5x - 3 = 12
Step-by-step explanation:
3 less means subtracting, it's going to be -3.
It says 3 less than five times a number, meaning we don't know the number, so we can put it as x.
3 less means your subtracting from something, which would make it 5x - 3.
Finally, they state that it equals 12, making the equation 5x - 3 = 12.
Heng Roth invests $9000 at 2%
per annum compound interest daily. What
is his amount at the end of the third day?
(1 year =365 days)
Answer:
After three days Heng will have 9000.15 in his account.
Step-by-step explanation:
In order to solve this problem, we must apply the correct formula, which is given below:
[tex]M = C*(1 + r/n)^{n*t}[/tex]
Where M is the final amount, C is the money invested, r is the annual interest rate, n is the number of times the money gets compounded in a year and t is the time elapsed. Since in this account the money is compounded daily, it means that for each year it gets compounded 365 times, therefore n = 365. The ammount will be compounded for 3 days, therefore we must convert this value to years in order to apply it in the "t" variable, we do that by dividing it by 365. With this knowledge we can solve the problem as shown below:
[tex]M = 9000*(1 + \frac{0.002}{365})^{365*\frac{3}{365}[/tex]
[tex]M = 9000*(1.000005479)^{3}\\M = 9000.15\\[/tex]
After three days Heng will have 9000.15 in his account.
Simplify the expression by combining like terms.

Which of the following tables represents the equation y=2x-1
Answer:
There are no tables, but... I made a quick graph.
Step-by-step explanation:
y=2x-1 means that you start at (0,-1), one down from the origin (0,0). From there, you go up 2 and right one (1, 2), as well as down 2 and left 1 (-1, -2), since the slope is 2 (or [tex]\frac{2}{1\\}[/tex]). The lines continues in both directions, of course.
The table for the equation is y = 2x - 1
x y
0 -1
1 1
2 3
How to determine the tableTo determine which table represents the equation y = 2x - 1, we substitute the values of x into the equation and check if the resulting y values match those given in the table.
Substitute the values 0, 1, and 2 into the equation y = 2x - 1 and calculate the corresponding y-values:
For x = 0:
y = 2(0) - 1
y = 0 - 1
y = -1
For x = 1:
y = 2(1) - 1
y = 2 - 1
y = 1
For x = 2:
y = 2(2) - 1
y = 4 - 1
y = 3
The corresponding y-values for x = 0, 1, and 2 are -1, 1, and 3, respectively.
