A manufacturer of handcrafted wine racks has determined that the cost to produce x units per month is given by C=0.3X^2+8,000. How fast is the cost per month changing when production is changing at the rate of 14 units per month and the production level is 70 UNITS?
Costs are ___ at the rate of $___ per month at this production level.
Answer:
Costs are changing at the rate of $588 per month at this production level.
Step-by-step explanation:
From the question, we have:
C = 0.3X^2 + 8,000 ........................ (1)
Differentiating equation (1) with respect to time, t, we have:
dC/dt = (0.3 * 2) X (dX/dt)....................... (2)
Where;
X = 70
dX/dt = 14
Substituting this into equation (2), we have:
dC/dt = (0.3 * 2) * 70 * 14
dC/dt = 588
This implies that costs are changing at the rate of $588 per month at this production level.

Which equation does the graph below represent?
y = 1/4x
y= 4x
y= -1/4x
y= -4x
Answer:
y = -4x
Step-by-step explanation:
y = mx+c
gradient, m
= (4-0)/(-1-0)
= -4
y-intercept, c
= 0
y = -4x+0
y = -4x

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes.
If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags? Explain.
Answer:
Machine A makes popcorn at a rate of 4.25 ozs per minute (12.75oz/3min).
Machine B makes popcorn at a rate of 4.5 ozs per minute (18oz/4min).
Machine A will make 4.25oz/min * 10minutes = 42.5oz of popcorn after 10 minutes
Machine B will make 4.5oz/min * 10 minutes = 45oz of popcorn after 10 minutes
After 10 minutes there will be a total of 42.5oz (Machine A) +45oz (Machine B) = 87.5oz.
So the answer is: Yes there will be (more than) enough popcorn if both machines make popcorn for 10 minutes.
If the question is wondering how many 9oz bags they can fill: 87.5oz/9oz per bag = 9.7222 bags. The machines can fill 9, 9oz, bags with some popcorn leftover.
Step-by-step explanation:
Machine A makes popcorn at a rate of 4.25 ozs per minute (12.75oz/3min).
Machine B makes popcorn at a rate of 4.5 ozs per minute (18oz/4min).
Machine A will make 4.25oz/min * 10minutes = 42.5oz of popcorn after 10 minutes
Machine B will make 4.5oz/min * 10 minutes = 45oz of popcorn after 10 minutes
After 10 minutes there will be a total of 42.5oz (Machine A) +45oz (Machine B) = 87.5oz.
So the answer is: Yes there will be (more than) enough popcorn if both machines make popcorn for 10 minutes.
If the question is wondering how many 9oz bags they can fill: 87.5oz/9oz per bag = 9.7222 bags. The machines can fill 9, 9oz, bags with some popcorn leftover.
Answer:
Yes
Step-by-step explanation:
Divide 12.75 by 3 to get the amount Machine A makes in 1 minute, 4.25 ounces.
Divide 18 by 4 to get the amount Machine B makes in 1 minute, 4.5 ounces
Multiply 4.25 by 10 for a total from Machine A, 42.5 ounces.
Multiply 4.5 by 10 for a total from Machine B, 45 ounces.
Add 42.5 to 45 totalling 87.5
Eight 9-ounce bags require 72 ounces of popcorn. So if both Machines made a total of 87.5 ounces they would have enough popcorn.

Find the sum of 2 1/9 + (-2/9) + 3 5/9
OA. -5
OB. 5
OC. 5 2/9
OD. 5 4/9
O E. 5 5/9
Answer:
5 4/9
Step-by-step explanation:
Convert a mixed number 2 19
to a improper fraction: 2 1/9 = 2 19 = 2 · 9 + 19 = 18 + 19 = 199
To find new numerator:
a) Multiply the whole number 2 by the denominator 9. Whole number 2 equally 2 * 99 = 189
b) Add the answer from previous step 18 to the numerator 1. New numerator is 18 + 1 = 19
c) Write a previous answer (new numerator 19) over the denominator 9.
Two and one ninth is nineteen ninths
Add: 19
9+ (-29) = 19 + (-2)9= 179
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(9, 9) = 9. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 9 × 9 = 81. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - nineteen ninths plus minus two ninths = seventeen ninths.
Conversion a mixed number 3 59
to a improper fraction: 3 5/9 = 3 59= 3 · 9 + 59= 27 + 51 = 329
To find new numerator:
a) Multiply the whole number 3 by the denominator 9. Whole number 3 equally 3 * 99 = 279
b) Add the answer from previous step 27 to the numerator 5. New numerator is 27 + 5 = 32
c) Write a previous answer (new numerator 32) over the denominator 9.
Three and five ninths is thirty-two ninths
Add: the result of step No. 2 + 32
9= 179+ 329 = 17 + 329 = 499
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(9, 9) = 9. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 9 × 9 = 81. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - seventeen ninths plus thirty-two ninths = forty-nine ninths.

The formula for the area of a circle is A = ar2 where A is the area ander is the radius.
Estimate the area of a circle where it = 3.142 and r = 8.6 cm.
Answer:
The area of circle is 232.23 cm²
Step-by-step explanation:
The formula used to calculate area of circle is: [tex]\mathbf{A=\pi r^2}[/tex]
Where [tex]\pi[/tex] = 3.14 and r is radius
We are given radius r = 8.6 cm
We need to find area of circle.
Using formula and finding area of circle
[tex]A=\pi r^2\\A=3.14\times(8.6)^2\\A=3.14\times 73.96\\A= 232.23 \ cm^2[/tex]
So, the area of circle is 232.23 cm²
Write the ratio as a fraction lowest terms 7 days to 13 days
Answer:
The answer is: [tex]\mathbf{Ratio \ as \ fraction =\frac{7}{13}}[/tex]
Step-by-step explanation:
We need to write ratio as a fraction lowest terms 7 days to 13 days
Ratio as fraction is written as: [tex]\frac{a}{b}[/tex] if we have a to b
So, in our case 7 days to 13 days
a= 7, b= 13
Writing ratio as fraction:
[tex]Ratio \ as \ fraction =\frac{7}{13}[/tex]
The fraction cannot be further simplified as already in lowest form so, the answer is: [tex]\mathbf{Ratio \ as \ fraction =\frac{7}{13}}[/tex]
which relations represent functions?
Can someone help pls !
Answer:
(B). [tex]A_{y}[/tex] = [tex]\left[\begin{array}{cc}12&7\\17&-51\end{array}\right][/tex]
Step-by-step explanation:
12x - 13y = 7
17x - 22y = - 51
A = [tex]\left[\begin{array}{cc}12&-13\\17&-22\end{array}\right][/tex]
[tex]A_{x}[/tex] = [tex]\left[\begin{array}{cc}7&-13\\-51&-22\end{array}\right][/tex]
[tex]A_{y}[/tex] = [tex]\left[\begin{array}{cc}12&7\\17&-51\end{array}\right][/tex]

Some marbles in a bag are red and the rest are blue. If one red marble is removed,
then one-seventh of the remaining marbles are red. If two blue marbles are removed
instead of one red, then one-fifth of the remaining marbles are red. How many
marbles were in the bag original
Pls give EXPLANATION
Answer:
22
Step-by-step explanation:
Let r be red and b be blue
1/7(r-1+b)=r-1
1/5(r+b-2)=r
r-1+b=7(r-1)
r+b-2=5r
r-1+b=7r-7
1=7r-7-5r
8=2r
r=4
1/5(4+b-2)=4
2+b=20
b=18
18+4=22

Determined to finish her milkshake before Diego, Lin now drinks her 12 ounce milkshake at a rate of 13 an ounce per second. Diego starts with his usual 20 ounce milkshake and drinks at the same rate as before, 23 an ounce per second.
Below is a graph of this system.
After how many seconds do both Diego and Lin have the same amount of milkshake left?
[ Select ]
How many ounces do both Diego and Lin have left of their milkshakes at that point?
[ Select ]
Answer: 24 seconds
4 ounces
Answer:
24 seconds and 4 ounces
Step-by-step explanation:
The point where both lines meet is the point where they are both equal.
The point where both lines meet is (24,4)
Since the x-axis represents seconds the x-coordinate will represent the number of seconds it takes for them to be equal which is 24.
Since the y-axis represents ounces the y-coordinate will represent the number of ounces they have when they are equal which is 4.
