Answer:
45 minutes
Step-by-step explanation:
If two people work together, the time it takes to frame will obviously be shorter. Since Jake Takes four times longer, he will only cut off a fourth of Jerry's time. Which is 15 mins. 60 mins - 15 mins = 45 mins.
The least common multiple that is divisible by both a and b is the smallest positive integer. It will take 4/5 hours for Jerry and Jake to frame a room working together.
What is LCM?The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.
Jerry can frame a room in 1 hour. Therefore, the rate at which Jerry frame the room is,
Rate of Jerry = 1/1 room per hour
= 1 room per hour
Jake can frame a room in 4 hours. Therefore, the rate at which Jake can frame the room is,
Rate of Jake = 1/4 room per hour
Now, the rate at which they two will work together is,
Rate of working together = 1 + 1/4 room per hour
= 5/4 room per hour
Further, the time it will take for the two of them to frame a room working together is,
Time = 1/Rate
= 4/5 hour

From house to his job as a janitor, you can walk in a straight line. In the afternoon he has to stop twice on his way home. His first stop is at the bodega to get something to eat. The bodega is exactly halfway between his house and the school. The second stop will be at OWL Barbershop for his haircut. The OWL Barbershop location partitions the way from Wilfred’s house and job in the ratio 3:1. The coordinates of his house are H (-3, -4) and his job coordinates are J(5, 0). Please use B to represent the Bodega and O to represent OWL Barbershop.
Answer:
The coordinates of Bodega is B(1,-2)
The coordinates of OWL Barbershop is O(3,-1)
Step-by-step explanation:
Coordinates of House H = (-3,-4)
Coordinates of Job J= (5,0)
His first stop is at the bodega to get something to eat. The bodega is exactly halfway between his house and the school.
Let B to represent the Bodega
Now to find coordinates of Bodega we will use use mid point formula since bodega is exactly halfway between his house and the school.
[tex]x=\frac{x_1+x_2}{2} , y = \frac{y_1+y_2}{2}\\(x_1,y_1)=(-3,-4)\\(x_2,y_2)=(5,0)\\x=\frac{-3+5}{2} , y = \frac{-4+0}{2}\\x=1, y = -2[/tex]
So, The coordinates of Bodega is B(1,-2)
Now we are given that The OWL Barbershop location partitions the way from Wilfred’s house and job in the ratio 3:1.
Le O to represent OWL Barbershop.
We will use section formula
[tex]x=\frac{mx_2+nx_1}{m+n} , y =\frac{my_2+ny_1}{m+n}\\(x_1,y_1)=(-3,-4)\\(x_2,y_2)=(5,0)\\m:n=3:1\\x=\frac{3(5)+1(-3)}{3+1} , y =\frac{3(0)+1(-4)}{3+1}\\x=3,y=-1[/tex]
So, The coordinates of OWL Barbershop is O(3,-1)
The graph shows the equation y = 2x – 3. Use the slider for a to move the vertical line on the graph. Based on the vertical line test, is this equation a function? Why or why not?
Answer:
Yes. The vertical line never touches the graph at more than one point at the same time.
Step-by-step explanation:
this is the plato and edmentum answer
(make sure this is the right question)
As the vertical line touches the graph of the equation y = 2x - 3 it is a function.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
Given, An equation y = 2x - 3.
Now, If we draw a vertical line and it touches the graph at only one point
the equation is a function but if the vertical line touches the graph at more than two points the equation is not a function.

Solve for n. 2 (4 + n) = 28
Answer:
n = 10
Step-by-step explanation:
=> 2(4 + n) = 28
=> 2(4) + 2(n) = 28
=> 8 + 2n = 28
=> 2n = 28 - 8
=> 2n = 20
=> n = 20/2
=> n = 10
Answer:
n = 10
Step-by-step explanation:
2(4 + n) = 28
Distribute:
(8 + 2n) = 28
Eliminate Parenthesis:
8 + 2n = 28
Cancel Out:
2n = 20

If the slope of a line is -1 and two points on the line are (-9, 3) and (-10, r), what is the value of r?
Answer:
[tex]r=4[/tex]
Step-by-step explanation:
We know that the slope of the line is -1.
We also know that the line passes through (-9, 3) and (-10, r).
We want to find the value of r.
First, let's figure out the equation of our line. We can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, let's substitute -1 for m. Since we know the point (-9, 3), let's use this for (x₁, y₁).
Substitute:
[tex]y-(3)=-1(x-(-9))[/tex]
Simplify:
[tex]y-3=-(x+9)[/tex]
Distribute:
[tex]y-3=-x-9[/tex]
Add 3 to both sides. So, our equation is:
[tex]y=-x-6[/tex]
It passes through (-10, r) and we want to find the value of r. So, let's substitute -10 for x and r for y, since -10 is our x and r is our y. So:
[tex]r=-(-10)-6[/tex]
Evaluate for r. Distribute:
[tex]r=10-6[/tex]
Subtract:
[tex]r=4[/tex]
So, the value of r is 4.
And we're done!

Select the locations on the number line to plot the points 5, 3, and −2
Answer:
To find the points, remember the definition of distance or difference.
First, the 5 is easy to find, is in the extreme right.
Now, the next number is 3.
The difference between 3 and 5 is:
3 - 5 = - 2
This means that the place of the 3 will be 2 units at the left of the 5.
The next number is -2
The difference between -2 and 5 is:
-2 - 5 = -7
This means that the -2 is located 7 units at the left of the 5.
Below is an image of the located points in a number line.
write an equation of the line that passes through the points (1,3) and (3,-5)
Joel used a half gallon of paint to cover 84 square feet of wall. He has 932 square feet of wall to paint. How many gallons of paint should he purchase?
I will give u a Brainly <33 :)
Answer:
6 Gallons of Paint
Step-by-step explanation:
If you use a half gallon of paint to cover 84 square feet, how much could you paint with a full gallon? Lets figure it out:
[tex]\frac{1}{2} = 84[/tex]
multiply both sides by 2 so that the 1/2 gallon is now 1 gallon:
[tex]\frac{1}{2} * 2 = 84 * 2[/tex]
1 gallon = 168 square feet
now, how many gallons does it take to paint 932 square feet?
Divide 932 by 168:
[tex]\frac{932}{168} = 5.548[/tex]
Just like you cant buy 2.374 cheeseburgers, you cant buy 5.548 gallons of something so we round up and will have some paint left over once the job is done. So 6 gallons is the answer
The amount of gallons needed is 5.55gallons approximately
If Joel used a half-gallon of paint to cover 84 square feet of wall, this can be expressed using the equality sign as:
1/2 gallons = 84 square feet
In order to find the number of gallons for 932 square feet of wall to paint, we will write:
x = 932 square feet
Divide both expressions
1/2x = 84/932
2x = 932/84
2x = 11.09
x = 11.09/2
x = 5.55 gallons
This shows that the amount of gallons needed is 5.55gallons approximately

How do you do this question?
Answer:
D and E
Step-by-step explanation:
y = (x + 1)²
If x = t + 1, then y = (t + 1 + 1)² = t² + 4t + 4.
If x = e²ᵗ + 1, then y = (e²ᵗ + 1 + 1)² = e⁴ᵗ + 4e²ᵗ + 4.
If x = cos t, then y = (cos t + 1)² = cos²t + 2 cos t + 1.
If x = t − 1, then y = (t − 1 + 1)² = t².
If x = t, then y = (t + 1)² = t² + 2t + 1.
