5 men can paint 2 identical houses in 3 days. Assuming
that all the men work at the same rate, how long
will it take 10 men to paint 8 such houses?
Plz help I’ll mark brainliest
Answer:
6 days
Step-by-step explanation:
If you like my answer than please mark me brainliest thanks
Answer:6 days
Step-by-step explanation:
because it means 5 men painted 1 house in 1.5days(3:2=1,5), so for 5 men to paint 8 houses they will need 12 days (1.5x8=12) divide 12 in half because there will be twice as much men(10) and you get 6 days
A bacteria culture doubles every 5 hours. Determine the hourly growth rate of the bacteria
culture. Round your answer to the nearest tenth of a percent.
Answer:
10
Step-by-step explanation:
Using an exponential function, it is found that the hourly growth rate of the bacteria culture is of 14.9%.
------------------------
An exponential function has the following format:
[tex]A(t) = A(0)(1+r)^t[/tex]
In which:
A(0) is the initial amount.r is the hourly growth rate.------------------------
Since it doubles every 5 hours, it means that:
[tex]A(5) = 2A(0)[/tex]
And we use this to find r.
------------------------
[tex]A(t) = A(0)(1+r)^t[/tex]
[tex]2A(0) = A(0)(1+r)^5[/tex]
[tex](1 + r)^5 = 2[/tex]
[tex]\sqrt[5]{(1 + r)^5} = \sqrt[5]{2}[/tex]
[tex]1 + r = 2^{\frac{1}{5}}[/tex]
[tex]1 + r = 1.149[/tex]
[tex]r = 1.149 - 1 = 0.149[/tex]
0.149*100% = 14.9%.
The hourly growth rate of the bacteria culture is of 14.9%.

Help me with math really quickly It costs $20 plus $1.50 per hour to rent a golf cart. a. Write an equation that shows the relationship between the cost of renting a golf cart (y) and
the number of hours it was rented (x). b. Graph your equation. Be sure to label your axis and chose an appropriate scale. c. How much does it cost to rent a cart for 5 hours? d. How many hours can you rent a cart for $32?
Answer:
a) 1.50x + 20 = y
c) $27.5
d) 8 hours
Step-by-step explanation:
a) 1.50 times x the amount of hours. 1.50 per hour. 1 hour would be 1.50 and 2 hours would be 3.00. Then just add 20 to that amount.
b) Don't really have time to graph, but here this is the graph using a graphing calculator. It intercepts at 20 because 20 is b, which is the y intercept.
c) Plug in 5 for x
d) Start with 1.50x + 20 = 32. You need to solve for x. Subtract 20 from both sides and you get 1.50x = 12. Divide both sides by 1.50 and you get x = 8. Since x representshe amount of hours, it would be x.
14 - 2(x + 8) = 5x - (3x - 34); Prove: x = -9
Step-by-step explanation:
14 - 2(x + 8) = 5x - (3x - 34)
14 -2x -16 = 5x -3x+34
-2x -2 = 2x+34
-2x-2x = 34+2
-4x = 36
x = 36/(-4)
x = -9

Find the inverse of f(x) = -4+7/2x
Answer:
2/7x + 8/7
Step-by-step explanation:
f(x) = -4 + 7/2x
y = -4+7/2x
Exchange x and y
x = -4 +7/2y
Solve for y
Add 4 to each side
x+4 = -4+4 +7/2y
x+4 = 7/2y
Multiply each side by 2/7
2/7(x+4) = 2/7 * 7/2y
2/7(x+4) = y
2/7x + 8/7

18. Solve x^2+ 6x - 16 = 0 by completing the square.
Please give detailed steps!!
Answer:
x1 = -8, x2= 2
Step-by-step explanation:
1. Write 6x as a difference
= x^2 + 8x - 2x - 16 = 0
2. Factor the expressions
= x ( x + 8 ) - 2x - 16 = 0
= x ( x + 8 ) - 2 ( x + 8 ) = 0
Factor out x + 8 from the expression
= ( x + 8 ) ( x - 2 ) = 0
3. When the product of factors = 0, at least one factor is 0
x + 8 = 0
x - 2 = 0
4. Solve the equation for x
x = - 8
x = 2
Therefore, the equation has 2 solutions :
x1 = -8, x2 = 2
The average number of road accidents that occur on a particular stretch of road during a month is 7. What is the probability of observing exactly three accidents on this stretch of road next month
Answer:
3/7 or 57.1%
Step-by-step explanation:
If the car wrecks happen 7 times a month and you see 3 wrecks, then you would have seen 3 out of the 7 wrecks. 3/7 or 57.1% of wrecks.
The required probability of observing exactly three accidents is 42.8%.
Give that,
The average number of road accidents that occur on a particular stretch of road during a month is 7. What is the probability of observing exactly three accidents on this stretch of road next month is to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
here,
Total number of samples = 7
Total number of favorable outcomes = 3
Required probability = 3 / 7 = 42.8%
Thus, the required probability of observing exactly three accidents is 42.8%.

Answer:
It is correct
Step-by-step explanation:
Has two solutions x = a and x = -a because both numbers are at the distance a from 0. You begin by making it into two separate equations and then solving them separately. An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.
let f(x)=2x-1 and g(x)=1/x. Find the value of f(g(7))
Answer:
-5/7
Step-by-step explanation:
We need to find g(7) first
All we have to is plug 7 in the place of x
g(7) = 1/7
Now we have f(1/7) = 2x - 1
f(1/7) = 2(1/7) - 1
f(1/7) = 2/7 - 1
Don't forget about common denominators
2/7 - 7/7 = -5/7
