if 125 men can do a piece of work in 120days, how many men would be sufficient to do the same work in 100days?
Answer:
x =150 men
Step-by-step explanation:
Think of the total as workdays
125men* 120days = 15000 workdays
We still need 15000 workdays
100 days * x = 15000workdays
Divide by 100
x = 15000/ 100
x =150 men
Answer:
150 men
Step-by-step explanation:
120 × 125 = 15000
15000 ÷ 100
150
An experiment has three steps with three outcomes possible for the first step, two outcomes possible for the second step, and five outcomes possible for the third step. How many experimental outcomes exist for the entire experiment
Answer:
30 experimental outcomes exist for the entire experiment.
Step-by-step explanation:
Fundamental counting principle:
States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.
In this question:
Three outcomes possible for the first step.
Two for the second step.
Five for the third step.
How many experimental outcomes exist for the entire experiment?
Steps are independent, so, by the fundamental counting principle:
3*2*5 = 6*5 = 30
30 experimental outcomes exist for the entire experiment.

Which of the following is the inverse of F(x) if F(x) = 6x?
O A. F(x) = 6x
O B. F(x) = x-6
O C. F(X) -
O D. F(x) = x + 6
The correct inverse of F(x) = 6x is y = x/6 according to given question
To find the inverse of a function, we need to interchange the roles of the dependent variable (x) and the independent variable (F(x)) and solve for the new dependent variable.
Given that F(x) = 6x, to find the inverse, we can follow these steps:
Replace F(x) with y: y = 6x.
Swap x and y: x = 6y.
Solve for y: Divide both sides by 6 to isolate y: y = x/6.
Therefore, the inverse function of F(x) = 6x is given by y = x/6.
Out of the options provided:
A. F(x) = 6x: This is the original function, not the inverse.
B. F(x) = x-6: This is not the correct inverse function.
C. F(X): This option is incomplete; it does not provide an equation for the inverse.
D. F(x) = x + 6: This is not the correct inverse function.
Therefore, the correct inverse of F(x) = 6x is y = x/6.

Kevin entered a pie eating contest. He ate 4 pies in 132 seconds. What is kevins unit rate? Awnser without units.
Answer:
Kevin eats 1 pie for every 33 seconds that pass
Step-by-step explanation:
A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.
If we were wondering how many seconds Kevin takes to eat a pie then the equation would look like:
132 seconds / 4 pies = 33 seconds per pie
33 seconds / 1 pie
However, if we were looking for how many pies Kevin eats in a second, then the equation would look like:
4 pies / 132 = .0303 or 3.03% of a pie per second
.0303 pies / 1 second

What is the volume in milliliters of 7.06 g of acetone?
Express your answer to three significant figures and include the appropriate units.
Answer:
V = 9 mL
Step-by-step explanation:
Given that,
The mass of acetone, m = 7.06 g
The density of acetone, d = 0.784 g/cm³
We need to find the volume of 7.06 g of acetone.
We know that,
Density = mass/volume
[tex]V=\dfrac{m}{d}\\\\V=\dfrac{7.06\ g}{0.784\ g/cm^3}\\\\V=9\ cm^3[/tex]
or
V = 9 mL
So, the required volume is 9 mL.

A 12.5 oz bag of Doritos costs $3.79. A 3 oz bag costs $1.00. What is the difference in unit rates?
Answer:
0
Step-by-step explanation:
12.5/3.79 = 3.2981530343
3.2981530343 rounded = 3.3
1/3 = 3.33333333333333
3.33333333333333 rounded = 3.3
3.3 - 3.3 = 0
9514 1404 393
Answer:
$0.03 per ounce
Step-by-step explanation:
The unit rate for the smaller bag is ...
$1.00/(3 oz) = $0.333 /oz
For the larger bag, it is ...
$3.79/(12.5 oz) = $0.303 /oz
Then the difference in unit rates is ...
$0.333 -0.303 = $0.03 . . . per ounce

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 378 people entered the park, and the admission fees collected totaled 1,042.00 dollars. How many children and how many adults were admitted?
Answer:
188 children, 190 adults
Step-by-step explanation:
For this equation, let c be the number of children, and a represent the number of adults.
On this day 378 total people were at the park, so
a + c = 378 eq 1
Each adult pays $4, so the admission fee for ALL adults will be $4 multiplied by the number of adults , a, so 4a
Use the same method for the children, and the total all children paid is 1.50c
From all the children and adults, the total was 1042, so merge the 2 cost variables together.
4a + 1.50c = 1042 eq 2
the 2 equations we will use are
a + c = 378
4a + 1.50c = 1042
From equation 1, subtract c from both sides, and
a = 378 - c eq 3
Substitute the value of a in eq 3 into equation 2
4a + 1.50c = 1042
4 (378 - c) + 1.50c = 1042
1512 - 4c +1.50 c = 1042 (collect like terms)
1512 - 1042 = 4c -1.50 c
470 = 2.5 c
c = 470 /2.5
c = 188 children
Substitute the value of c into eq 3 to get the value of a
a = 378 -c
a = 378 - 188
a = 190 adults

What is the probability of an event?The probability of an event is the ratio of the number of outcomes favorable to the event to the total number of outcomes for the event. This represents the chance for the event to take place.
If A is the event, n is the number of outcomes favorable to the event and S is the total number of outcomes, then the probability of the event A is given as:
P(A) = n/S.
How do we solve the given question?We are given a two-way table showing the number of freshmen, sophomores, juniors, and seniors in the class with respect to their gender.
We are asked to find the probability of selecting a junior student while picking a random student from the class.
Let the event of selecting a junior student from the class be A.
Number of favorable outcomes to event A (n) = 2 + 6 = 8 (junior males + junior females)
Total number of outcomes (students in the class) (S) = 4 + 6 + 2 + 2 + 3 + 4 + 6 + 3 = 30.
∴ The probability that the selected student is a junior is given by:
P(A) = n/S = 8/30
or, P(A) = (8/30)*100% = 26.67% = 27% (rounding to the nearest whole percent).
∴ The probability that the selected student is a junior is 27%.
