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.

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.

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.
3) 15x + 4 = 106
Can someone show me the steps ? Pls :)
1) Subtract 4 from both sides to get 15x = 102
2) Divide by 15 on both sides to get x = 6.8
Answer:
x=6.8
Step-by-step explanation:
15x + 4 = 106
subtract 4 from both sides
15x=102
divide both sides by 15
x=6.8

What is factoring?A polynomial with coefficients in a certain field or in integers is expressed as the product of irreducible factors with coefficients in the same domain in mathematics and computer algebra, which is known as polynomial factorization.
Given
Based on the given conditions, formulate: 8 x = 144
Divide both sides of the equation by the coefficient of variable: x = 144/8 out the common factor: x = 18

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]

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

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.
