Andy had 6 2/3 cups of juice. How many 2/3-cup servings can he pour?
Answer: 10
Step-by-step explanation:
First, you need to change 6 and 2/3 into an improper fraction which is 20/3. Then, you need to divide 20/3 by 2/3 to find your answer. To do this, simply turn 2/3 to 3/2 and multiply it by 20/3. 20/3 x 3/2 = 60/6. 60/6 in simplest form is 10. Therefore, you answer is 10.

The sum of two numbers is 175. The first number is 35 less than five times the second number. Write and solve a system of equations to find the two numbers
Answer:
FIrst number = 35
Second number = 140
Step-by-step explanation:
Sum = 175
Second number = x
First number = 5x - 35
=> x + 5x - 35 = 175
=> 6x - 35 = 175
=> 6x - 35 + 35 = 175 + 35
=> 6x = 210
=> 6x/6 = 210/6
=> x = 35
Second number = x = 35
First number = 5x - 35 = 5 * (35) - 35 = 175 - 35 = 140
First number = 140
Second number = 35
Given:
PQ
⊥
QR
, PR = 20,
SR = 11, QS = 5
Find: The value of PS. EXTRA POINTS
Answer:
[tex]PS=13\text{ units}[/tex]
Step-by-step explanation:
So, we know that PR is 20, SR is 11, and QS is 5.
We also know that PQ is perpendicular to QR, forming the right angle at ∠Q.
We know all the side lengths except for PQ and PS (the one we want to find). Notice that if we find PQ first, we can then use the Pythagorean Theorem to find PS since we already know QS.
So, let's find PQ.
We can see that we can also use the Pythagorean Theorem on PQ. PQ, QR, and PR (the hypotenuse) will be our sides. So:
[tex](PQ)^2+(QR)^2=(PR)^2[/tex]
We know that PR is 20.
QR is the combined length of QS+SR, so QR is 5+11 or 16.
So, substitute:
[tex](PQ)^2+(16)^2=(20)^2[/tex]
Solve for PQ. Square:
[tex](PQ)^2+256=400[/tex]
Subtract 256 from both sides:
[tex](PQ)^2=144[/tex]
Take the square root of both sides:
[tex]PQ=12[/tex]
So, the side length of PQ is 12.
Now, we can use the Pythagorean Theorem again to find PS. Notice that PQ, QS, and PS also form a right triangle, with PS being the hypotenuse. So:
[tex](PQ)^2+(QS)^2=(PS)^2[/tex]
We already know that QS is 5. We also just determined that PQ is 12. Substitute:
[tex](12)^2+(5)^2=(PS)^2[/tex]
Square:
[tex]144+25=(PS)^2[/tex]
Add:
[tex]169=(PS)^2[/tex]
Take the square root of both sides:
[tex]PS=13[/tex]
Therefore, the length of PS is 13 units.
And we're done!
The answer to this is PS=13.

Step-by-step explanation:
A rectangular container can hold 45 candles, while a cylindrical container holds 41 candles. Each rectangular
container costs the company $16, while the cylindrical container costs the company $15. If the company needs to
package 6,400 candles, should it use only rectangular or only cylindrical containers to minimize costs? Explain.
How many rectangular containers will be necessary to package 6,400 candles?
How many cylindrical containers will be necessary to package 6,400 candles?
Which container should the company use to minimize costs? Explain.
Answer:
a) no
b) 143 rectangular containers
c) 157 cylindrical containers
d) both (preferring rectangular for the bulk of an order)
Step-by-step explanation:
a) If the company needs to package 6,400 candles, should it use only rectangular or only cylindrical containers to minimize costs?
No.*
For packaging 41 candles or fewer, the cylindrical container costs less than the rectangular one.
For packaging 6400 candles, there will be 10 candles left over if rectangular containers are used for most of the packaging needs. A dollar can be saved by packaging these remaining candles in a cylindrical container.
__
b) How many rectangular containers will be necessary to package 6,400 candles?
6400/45 = 142 10/45
If rectangular containers are used for all, then 143 are needed.
__
c) How many cylindrical containers will be necessary to package 6,400 candles?
6400/41 = 156 4/41
If cylindrical containers are used for all, the 157 are needed.
__
d) Which container should the company use to minimize costs?
The cost of 143 rectangular containers is 143×$16 = $2288
The cost of 157 cylindrical containers is 157×$15 = $2355
The cost of 142 rectangular and 1 cylindrical container is $2287
If only one shape container is used, the company should use rectangular containers to minimize cost. If either shape can be used, cost will be minimized by using one cylindrical container for the remnant of the order.
_____
* This question is directed solely at the cost of materials required for packaging. We have advocated that both rectangular and cylindrical containers be made available. As a practical matter, the cost to the company of maintaining inventory of both sizes of containers may exceed the savings associated with using a cheaper container for smaller orders.

4. Odette Alverez works at the Digitech Warehouse eight hours a day, earning $9.48 an hour. She is asked to work two additional hours at time and a half to help prepare for an incoming shipment of merchandise. How much will she earn for these two hours of overtime?
Answer:
$28.44
Step-by-step explanation:
Time and a half is the normal rate of pay when working overtime at any job and is calculated as 1.5 times the regularly hourly wage of the employee. Therefore we can calculate how much she earns per hour of overtime by doing the following...
$9.48 * 1.5 = $14.22 per hour
Now we can see that Odette earns $14.22 per hour of overtime, since she worked two hours we simply multiply this amount by 2.
$14.22 * 2 = $28.44
Odette Alvarez earned $28.44 for the two hours of overtime.

e. What number, when reduced by 20%, becomes 500?
f. What amount increased by 100% will equal $310
g. After deducting 20% from a sum of money, the remainder is $500. What was the
original amount?
Also what is 1.40 to percent and fraction
Pls help fast
Answer:
E: 625
F: 155
G: 625
Step-by-step explanation:
Hi!
E.
A number, reduced by 20% is 500.
Originally, that number was at 100%.
Reduced = subtraction, so that number = 100%-20%, or 80%.
80% of a number = 500.
80% = .8
.8x = 500
Divide both sides by .8
x = 625
F.
A number that is increased by 100% is a number that is doubled (multiplied by 2).
2x=310
x=155
G.
Originally, the money was at 100%. After being reduced by 20%, the money is at 80% (.8).
.8x = 500
Once again, the answer is 625.
H (?)
To change a decimal to a percent, we multiply by a 100.
1.40 * 100 = 140%
As a fraction: 140/100
Denise and Donna want to exchange secrets from across a crowded whispering gallery. Recall that a whispering gallery is a room which, in cross section, is half of an ellipse. If the room is 30 feet high at the center and 90 feet wide at the floor, how far from the outer wall should each of them stand so that they will be positioned at the foci of the ellipse? Fill in the blank: Denise and Donna should each stand _____ ft from the outer wall so that they will be positioned at the foci of the ellipse. Round your answer to the nearest whole ft (no decimal places).
Answer:
34 feet
Step-by-step explanation:
From the question, we are told that:
If the room is 30 feet high at the center and 90 feet wide at the floor,
Entire width of the room = 90 feet = 2a
a = 90/2 = 45
Height of the room = b = 30 feet
Foci (c)² = a² - b²
c = √a² - b²
c = √45² - 30²
c = √1125
c = 33.541019662 feet
Approximately to the nearest whole number = 34 feet
Denise and Donna should each stand 34 ft from the outer wall so that they will be positioned at the foci of the ellipse
Classify is the function as increasing decreasing or constant l
f(x) = 5x
Anyone know the answer .?
Answer:
Increasing
Step-by-step explanation:
Remember that f(x) is the same as y in slope intercept form y = mx + b.
We don’t have a number for “b” which means the line goes across the origin.
Since 5 replaces m, that is the slope and since it’s positive, it is increasing.

Answer:
Riley made a mistake in step 4.
Step-by-step explanation:
In step 4, Riley applied the division property of equality to divide both sides of the equation by 2. However, the variable is multiplied by -2, not 2. So, the opposite operation Riley should have done is divide both sides of the equation by -2. Therefore, Riley made a mistake in step 4.

How do you do this question?
Step-by-step explanation:
y = 3 + 8x^(³/₂), 0 ≤ x ≤ 1
dy/dx = 12√x
Arc length is:
s = ∫ ds
s = ∫₀¹ √(1 + (dy/dx)²) dx
s = ∫₀¹ √(1 + (12√x)²) dx
s = ∫₀¹ √(1 + 144x) dx
If u = 1 + 144x, then du = 144 dx.
s = 1/144 ∫ √u du
s = 1/144 (⅔ u^(³/₂))
s = 1/216 u^(³/₂)
Substitute back:
s = 1/216 (1 + 144x)^(³/₂)
Evaluate between x=0 and x=1.
s = [1/216 (1 + 144)^(³/₂)] − [1/216 (1 + 0)^(³/₂)]
s = 1/216 (145)^(³/₂) − 1/216
s = (145√145 − 1) / 216
I thought of number J, and then subtracted half of it from 34.
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let me help out.
You said that you thought of number J, and then subtracted half of it from 34. This can be mathematically written as:
= 34 - (J/2)
Let's reframe the question and assume that you thought of a number J, and then subtracted half of it from 34 and the answer you get is 12. To find J goes thus:
You subtract half of J from 34 and equate it to 12. This will be:
34 - (J/2) = 12
Collect like terms
34 - 12 = J/2
22 = J/2
J = 22 × 2
J = 44
In this scenario, J = 44. We can check to confirm.
Check: 34 - (J/2)
= 34 - (44/2)
= 34 - 22
= 12
Answer:
34 - (J/2)
