Laundry detergent comes in 2 sizes. Box A is $7.62 for 2.5 Litres, Box B is
$5.74 for 1.5 Litres. Which is the better deal and by how much?
Answer:
$7.25 = 2.5, so divide by 7.25 by 5 = 1.45 <- better deal & $0.46333333333 per litre.
5.74 = 1.5, so divide 5.74 by 3 = 1.91333333333
Step-by-step explanation:
Why 3 and 5 - 0.5 is 5 times 2.5 and so is 0.5 times 3= 1.5
1.91333333333 - 1.45 = $0.46333333333 per litre.

Find PUR, given the following sets:
P = {b, d, f, g}
Q = {a, b, c, d]
R = {c, e, f, g}
S = {a, d. g}
Answer:
={b,c,d,e,f,g}
Step-by-step explanation:
={b,c,d,e,f,g}
Answer:
PUR= b, d, f, g, c, e
Step-by-step explanation:
To fid the answer you unite the sets together. When uniting the sets you only write the letter once even if it appears in both sets.
So when we combine p and r the answer we get is:
PUR= b, d, f, g, c, e

A candy distributor needs to mix a 30% fat-content chocolate with a 40% fat-content chocolate to create 150 kilograms of a 32% fat-content chocolate. How many kilograms of each kind of chocolate must they use?
Answer:
120 kg of 30% fat-content chocolate and 30 kg of 40% fat-content chocolate.
Step-by-step explanation:
We are given that a candy distributor needs to mix a 30% fat-content chocolate with a 40% fat-content chocolate to create 150 kilograms of a 32% fat-content chocolate.
Let the amount of 30% fat-content chocolate be 'x' and the amount of 40% fat-content chocolate be 'y'.
So, according to the question;
x + y = 150 ------------ [equation 1]
and [tex]30\% \text{ of } x + 40\% \text{ of } y=32\% \text{ of } 150[/tex]
[tex]30x+40y= 32 \times 150[/tex]
[tex]30x+40\times (150-x)= 4800[/tex]
[tex]30x+6000-40x= 4800[/tex]
[tex]10x = 6000-4800[/tex]
[tex]x=\frac{1200}{10}[/tex]
x = 120 kg
Now, putting the value of x in equation 1, we get;
x + y = 150
120 + y = 150
y = 30 kg
Hence, 120 kg of 30% fat-content chocolate and 30 kg of 40% fat-content chocolate.

How do you do this question?
Answer:
1) ∫₀¹ 2π x (x − x²) dx
4) ∫₀¹ π ((√y)² − y²) dy
Step-by-step explanation:
The solid formed is a hollow, upside down cone. We can either use washer method or shell method to find the volume.
If we use washer method, the thickness of the washers is dy. The outside radius is R = x₂ = √y, and the inside radius is r = x₁ = y.
Therefore, the volume of each washer is:
dV = π (R² − r²) t
dV = π ((√y)² − y²) dy
The total volume is the sum of all washers from y=0 to y=1.
V = ∫ dV
V = ∫₀¹ π ((√y)² − y²) dy
If we use shell method, the thickness of each shell is dx. The radius of each shell is r = x. The height of each shell is h = y₂ − y₁ = x − x².
Therefore, the volume of each shell is:
dV = 2π r h t
dV = 2π x (x − x²) dx
The total volume is the sum of all shells from x=0 to x=1.
V = ∫ dV
V = ∫₀¹ 2π x (x − x²) dx
From the drawing above, Bryan discovered that his area was 2 less than
Jon's area. What is the reasonable value of x?
Answer:
1
Step-by-step explanation:
The region between the graphs of X = y2 and X = 5y is rotated around the line y=5. The volume of the resulting solid is_________.
Answer and Step-by-step explanation:
The volume of the resulting solid is shown below:-
The lines in for
y can be y = sqrt(x) using square root
and y = x ÷ 5
In this, the intersect is done when sqrt(x) = x ÷ 5 using square root
Now
x = x^2 ÷ 25
x = 0
or
x = 25
so outermost is x ÷ 5 innermost is sqrt(x) using square root
Therefore A is
= integral of pi ( (x ÷ 5-5)^2 - (sqrt(x)-5)^2) using square root
from 0 to 25
= 625 pi ÷ 6
You take your car to an auto repair shop. The charge for repairs is $48 per hour plus the cost of parts. If
the car needs new parts that cost $256 and the final bill was $616, then how long did it take to repair the
car?
Answer:
7.5 Hours
Step-by-step explanation:
48x + 256 = 616
- 256 = -256
-----------------------------------
48x = 360 divide both side by 48
----- -------
48 48
x = 7.5
You want to get an idea of how much your children will benefit from the education system in a state. Which column of numbers will you use for your analysis? Why?
use the Per-Pupil Expenditure column to compare how much each state spends on average for each student. Total expenditure for the state can be misleading. A state with a high number of students could have a high overall expenditure, even if it doesn't spend very much on each student. I'm more concerned about how much the state is likely to spend on each of my children, not how much they spend overall.

Suppose PR = 54, solve for QR
We will use the segment addition postulate.
PQ + QR = PR
4x - 1 + 3x - 1 = 54
7x - 2 = 54
7x = 56
x = 8
So QR is 3(8) - 1 or 24 - 1 which is 23.
Answer:
QR is 23
Step-by-step explanation:
PR = 54 Which means:(4x-1)+(3x-1)=54We can solve for x to find what QR is:7x-2 =54 7x=56x=8Plug in x for QR equation:3(8)-1 = 24-1=2323 is the answer
State the size of angle OAB, giving a reason for your answer
Answer:
Angle OAB = 90°
Reason: tangent theorem of a circle
Step-by-step explanation:
The diagram given shows a tangent line of the given circle with center O. The tangent touches the circle at point A.
The diagram also shows the radius of the circle, OA, drawn from the center to the circle to meet at the point of tangency.
Thus, according to the Tangent Theorem of a circle, the point at which the radius drawn from the center meets the point of tangency = 90°. The tangent is perdendicular to the radius drawn to meet at the point of tangency.
Therefore, angle OAB = 90°

What is the solution to 10(3x−5)=−20
Answer:
x = 1
Step-by-step explanation:
Apply the distributive property. It should now look like this: 30x - 50 = -20Add 50 to each side, so it now looks like this: 30x = 30Divide each side by 30 to cancel out the 30 next to x. It should now look like this: x = 1I hope this helps!

one thousand seven thousand,eight hundred ten number form.
Answer:
one hundred seven thousand?
Step-by-step explanation:
107,810
3193.55767741 round to the nearest thousand
Answer:
3000
Step-by-step explanation:
Rounding to the nearest thousand implies not writing any significant figure after the digit located in the column of the thousand. In this case, what you have in that column is the number 3 (which is followed by a 1 in the column of the hundreds) so you need to round the number to 3000.
If the number that followed the 3 was 5 or larger, you would have rounded it to 4000.
Answer:
3,000
Step-by-step explanation:
The answer is 3,000 because:
1) The number in the hundreds place is 1, which is less than 5. Therefore, the number in the thousands place stays the same.
2) Whenever you are rounding with decimals, you have to leave the numbers after the decimal point.

Solve 5x + 2 = 3x -8
Step-by-step explanation:
5x-3x=-8-2
2x=-10
x=-10/2
x=-5
Answer: x=-5
Step-by-step explanation:
Given
5x + 2=3x -8
Subtract 2 on both sides
5x + 2 - 2=3x - 8 - 2
5x=3x-10
Subtract 3x on both sides
5x - 3x=3x - 10 -3x
2x=-10
Divide 2 on both sides
2x / 2=-10 / 2
x=-5
