one student can paint a wall in 10 minutes another student can paint the same wall in 15 minutes working together how long will it take for them to paint the wall?
Answer:
6 min
Step-by-step explanation:
given that the rate for the first student is 10 min per wall
we can express this in wall per minute by taking the reciprocal
hence student 1's unit rate = 1/10 wall per min
similarly, we can express student 2's unit rate as 1/15 wall per min.
if we add up the two, we will get the amount of wall painted by two people working together per min
amount of wall painted per min by 2 people
= wall per min of person 1 + wall per min of person 2
= 1/10 + 1/15
= 3/30 + 2/30
= 5/30
= 1/6 wall per min.
to convert this to minutes per wall, we take the reciprocal:
number of minutes that both people will take to paint the wall
= 1 / (1/6)
= 6 min per wall (answer)

What is the run of a 50% slope with a rise of 50 feet?
A. 100 feet
B. 55 feet
C. 25 feet
D. 2500 feet
E. 50 feet
Rise of the line with 50% slope and 50 feet rise = 100 feet
Option (A) will be the answer.
Slope of a line: Slope of a line is given by the expression,
Slope = [tex]\frac{\text{Rise}}{\text{Rus}}[/tex]
Given in the question,
Slope of the line = 50%
= [tex]\frac{50}{100}[/tex]
= 0.5
Rise has been given as 50 feet.
Substitute the values in the expression for the slope,
[tex]0.5=\frac{50}{\text{Run}}[/tex]
Run = [tex]\frac{50}{0.5}[/tex]
= 100 feet
Therefore, run for the given line will be 100 feet.
Option A will be the answer.

The distance from the origin to the point (−15,20) is
Answer:
25
Step-by-step explanation:
distance between two points is
d=√((x2-x1)^2+(y2-y1)^2)
in this case x2=-15 ,x1=0,y2=20,y1=0
so
d=√((-15-0)^2+(20-0)^2)
d=√(15^2+20^2)
d=√(225+400)
d=√625
d=25

Step-by-step explanation:
Answer:
m<1 = 75
m<2 = 55
m<3 = 55
Step-by-step explanation:
Well <1 + 50° is vertical to 125 so do this
<1 + 50 = 125 (subtract 50 on both sides)
<1 = 75
Now <1 + <2 + 50° = 180
We know what <1 is so..
75 + <2 + 50 = 180 (collect like terms)
125 + <2 = 180 (subtract 125 on both sides)
<2 = 55
Since <2 and <3 are vertical that means they equal the same so
<3 = 55

What is the equation of the line in slope intercept form? Enter your answer in the boxes.
Answer:
the answer is y= 5/2 x +5
Answer:
y = [tex]\frac{5}{2}[/tex] x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}=x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 5)
m = [tex]\frac{5-0}{0+2}[/tex] = [tex]\frac{5}{2}[/tex]
The line crosses the y- axis at (0, 5 ) ⇒ c = 5
y = [tex]\frac{5}{2}[/tex] x + 5 ← equation of line

Is the percentage illumination of the moon's surface a linear function of the day
Answer:
No (The linear model did a very bad job of approximating the data.)
I am so sorry if this in incorrect.
The percentage illumination of the moon's surface is not a linear function of day
How to determine the true statement?From the complete question, the dataset can be represented using the following table:
Days Percentage Illumination
1 2%
2 6%
3 50%
4 100%
Notice that as the number of days increase by 1, the percentage illumination of the moon increase at different intervals
This means that the percentage illumination is not a linear function of day

What is the answer for number 2
Answer:
Your answer would be x = 63
Step-by-step explanation:
What I would do first is to isolate the -1/9x, which means I would subtract 17 on each side, giving me -1/9x = -7
Next I would multiply -9 (which is the inverse of -1/9) on both sides, negating the negative sign and making 63 positive, and thus isolating x as well.

You must count the distance between so if you look at where it lines up perfect -3,0 up to 2 the distance is 5
Answer:
k = - 5Step-by-step explanation:
The slopes are same and y-intercepts are:
2 for f and -3 for gSince we have:
g(x) = f(x) + kWe can find the value of k:
-3 = 2 + kk = -3 - 2k = -5Answer is k = - 5
