Jerry can do the job in approx 17 minutes working alone.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Tom can do a job in 210 minutes and assuming Jerry to do the job
in x minutes and work to be 1.
∴ 1/210 + 1/x = 1/52.
1/x = 1/52 - 1/210.
1/x = (210 - 52)/2730.
1/x = 158/2730.
1/x = 79/1365.
x = 1375/79.
x = 17 minutes approx.

B is the midpoint of AC. if AB = x+5 and BC = 2x-11, find the measure of AB
Answer:
2 is the answer
Step-by-step explanation:
Answer:
AB = 21
Step-by-step explanation:
Since B is the midpoint of AC , then
BC = AB
2x - 11 = x + 5 ( subtract x from both sides )
x - 11 = 5 ( add 11 to both sides )
x = 16
Then
AB = x + 5 = 16 + 5 = 21

A jar contains 2 orange, 4 green, 2 white and 2 black balls. What is the probability of drawing an orange ball without putting it back, then drawing a black ball? (write your answer as a simplified fraction)
Answer:
2/45
Step-by-step explanation:
We are told that:
A jar contains 2 orange, 4 green, 2 white and 2 black balls.
The total number of balls in the jar is calculated as:
2 orange balls + 4 green balls + 2 white balls + 2 black balls = 10 balls
The probability of drawing an orange ball = P(Orange) = 2/10
The probability of drawing a black ball = P(Black) = 2/10
Therefore, the probability of drawing an orange ball without putting it back, then drawing a black ball is calculated as:
2/10 × 2/9 = 4/90
= 2/45

Answer:
(E) 72 w^2 is the answer
Step-by-step explanation:
outer square area is 81 w^2
inner square area is 9 w^2
subtracting outer - inner we can get the shaded area
so 81 -9= 72w^2
Answer:
E. 72w²
Step-by-step explain:
Area I = a × a= 9w × 9w
= 81w²
Area II = a × a= 3w × 3w
= 9w²
Shaded area = Area I - area II= 81w² - 9w²
= 72w²

|x+1|=|2x-6|
Answer:
x = 5, and/or x= - 7/3
Step-by-step explanation:
|x+1|=|2x+6|
We know eitherx+1=2x+6orx+1=−(2x+6)
x+1=2x+6(Possibility 1)
x+1−2x=2x+6−2x(Subtract 2x from both sides)
−x+1=6
−x+1−1=6−1 (Subtract 1 from both sides)
−x=5
(Divide both sides by -1)
x=−5
x+1=−(2x+6)(Possibility 2)
x+1=−2x−6(Simplify both sides of the equation)
x+1+2x=−2x−6+2x(Add 2x to both sides)
3x+1=−6
3x+1−1=−6−1(Subtract 1 from both sides)
3x=−7
Divide both sides by 3
x= −7 / 3

What is (8 - 2) - 6?
Answer:
The answer is Zero
Step-by-step explanation:
So you always do what is in the parentheses first no matter what so in this case you would do 8 - 2 which is 6 then you would do the rest of the equation in order so that means if there were multiplication and division and multiplication came second do division first don't just do the multiplication so any way you got the answer 6 and the next step is to subtract 6 from the answer you just got so now your equation is 6 - 6 which is zero hope this helps plz mark me as brainliest
Jeremy rounded the weight of his fruit to the nearest whole. He said his bag of apples weighed 4 pounds. What could have been the actual weight of his bag of apples? Group of answer choices
Answer: 3.5 - 4.4 pounds
Step-by-step explanation:
You included no options so I answered with the range of the answer.
When rounding a number up to the nearest whole number, the number needs to have the first decimal being 0.5 and above all the way to 0.9.
When rounding a number down to the nearest whole number, the number needs to have its first decimal being 0.1 to 0.4 to be rounded down.
For instance, 3.5 to 3.9 would get rounded up to 4 pounds.
4.1 to 4.4 would be rounded down to 4 pounds.
what is the value of x
Answer:
8
Step-by-step explanation:
Lines have angles that are equal to 180. Therefore, because we already have 140 of the 180 necessary, we can subtract 140 from 180 to get 40. 40 divided by 5 is 8.
Hope that this helps!
Answer:
I. x=8
Step-by-step explanation:
lines form 180° angles so
140 +5x= 180 ; subtract 140 from both sides
5x= 180-140; divide both sides by 5
x= 40/5 = 8

These box plots show daily low temperatures for a sample of days in two
different towns.
Degrees (F)
Which statement is the most appropriate comparison of the spreads?
Answer:
A
Step-by-step explanation:
In a box plot, interquartile range (IQR) can be used to describe the spread of any given data.
IQR = Q3 - Q1
✔️IQR for Town A:
Q3 = 40
Q1 = 20
IQR = 40 - 20 = 20°
✔️IQR for Town B:
Q3 = 30
Q1 = 20
IQR = 30 - 20 = 10°
We can conclude that the IQR for town A, 20°, is greater than the IQR for town B, 10°.
