Answer: Willis will take 3 hours to paint the room by himself.
Step-by-step explanation:
Given: Time taken by James to complete job by himself = 6 hours
Let Time taken by Willis to complete job by himself = t hours
Together they take 2 hours.
[tex]\dfrac{1}{6}+\dfrac{1}{t}=\dfrac{1}{2}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{2}-\dfrac{1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{3-1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{2}{6}\\\\\Rightarrow\ t=\dfrac{6}{2}\\\\\Rightarrow\ t=3[/tex]
So, Willis will take 3 hours to paint the room by himself.

LOOK AT ATTACHED IMAGE
CHOOSE ONE ANSWER
A. Martin climbs at a rate of 20 meters per hour
B. Alexia take 0.21 of an hour to climb one meter
C. Martin climbs at a rate of 0.20 meters per hour
D. Alexia climbs a rate of 15 meters per hour.
Answer:
Martin climbs at a rate of 20 meters per hour
Step-by-step explanation:
Martin and Alexia are rock climbing. Each person's rate stays the same for the first hour they climb.
For Martin's,
Distance = [tex]3\dfrac{1}{3}\ m=\dfrac{10}{3}\ m[/tex] in 1/6 hour
Rate is given by :
[tex]R=\dfrac{\frac{10}{3}}{\frac{1}{6}}\ m/h\\\\=\dfrac{10}{3}\times 6\\\\=20\ \text{meters/hour}[/tex]
For Alexia,
Distance = [tex]17\dfrac{1}{2}\ m=\dfrac{35}{2}\ m[/tex] in 5/6 hour
Rate is given by :
[tex]R=\dfrac{\frac{35}{2}}{\frac{5}{6}}\ m/h\\\\=\dfrac{35}{2}\times \dfrac{6}{5}\\\\=21\ \text{meters/hour}[/tex]
Hence, the correct option is (A) "Martin climbs at a rate of 20 meters per hour"
Your friend Jesse has just started his first scholarship application, and you notice that the application is asking
for his credit card information. You quickly tell him it could be a scam and give him three more signs to look
out for. What three signs do you tell him?
Answer:
Nobody representing a legitimate scholarship can or will be able to guarantee that you’ll win. Some services even boast they can guarantee the actions of another organization – they can’t. There are false promises and will likely result in something other than you obtaining money for school.
If someone contacts you, via phone, mail or email, offering you a scholarship, and you never requested information from that provider, be very careful. Scholarships are awarded to you after an application process – they are not just given out to random students – no matter how special they are.
Applying for legitimate scholarships does not cost money -- EVER! Submitting such applications will cost you time and effort, but should never cost money, no matter how small the amount.
Scholarships do have deadlines; however, they are usually clearly stated within the application guidelines. Legitimate providers don’t pressure students into applying for their scholarships; they have enough interest on their own. They also ensure that students have ample time to work on their scholarship applications and essays. If you ever feel pressured and are observing that it’s a “now or never” scenario, the scholarship is likely a scam.

When a driver applies the brakes, the tires lock but the car will continue to slide, leaving skid marks on the road. You can approximate the speed at which a car was traveling on a dry road based on the length of a skid mark left by the car using the formula Speed = (30xlengthx0.75)1/2, where speed is measured
in miles per hour and length is measured in feet. At approximately what speed
was a car traveling if it left a 50-foot long skid mark? Round to the nearest tenth.
.
The speed of the car was 33.5 miles per hour on the road on the basis of the skid mark it leaves behind on the road.
Given that, when a driver applies the brakes, then the tires lock but the car continue to slide, and leaves a skid mark on the road. By using the length of the skid mark we can approximate the speed of the car by which it was travelling on the road. The formula which we will be using to approximate the speed = √30 × Length of the skid mark × 0.75, where the speed is measured in miles per hour and the length is measured in feet.
Length of the skid mark on the road = 50 feet
speed of the car = √30 × Length of the skid mark × 0.75
simply put the value of length of the skid mark in the above formula and solve accordingly.
=√30 × 50 × 0.75
=√1125
=33.5
∴ The speed of the car was 33.5 miles per hour when it was on the road and leave behind a 50 feet skid mark on the road.

Rearranging the expression [tex]x=\frac{2w+1}{5-3w}[/tex] to make w the subject we get [tex]\mathbf{w=\frac{1-5x}{-3x-2} }[/tex]
Step-by-step explanation:
We need to rearrange the expression [tex]x=\frac{2w+1}{5-3w}[/tex] to make w the subject.
[tex]x=\frac{2w+1}{5-3w}\\x(5-3w)=2w+1\\5x-3wx=2w+1\\[/tex]
Subtract 2w on both sides
[tex]5x-3wx-2w=2w+1=2w\\5x-3wx-2w=1\\[/tex]
Subtract 5x on both sides
[tex]5x-3wx-2w-5x=1-5x\\-3wx-2w=1-5x\\[/tex]
Taking w common on left hand side
[tex]w(-3x-2)=1-5x\\[/tex]
Divide both sides by -3x-2
[tex]\frac{w(-3x-2)}{-3x-2} =\frac{1-5x}{-3x-2}\\w=\frac{1-5x}{-3x-2}[/tex]
So, rearranging the expression [tex]x=\frac{2w+1}{5-3w}[/tex] to make w the subject we get [tex]\mathbf{w=\frac{1-5x}{-3x-2} }[/tex]

Tony and Mia want to go to the Gwinnett Carnival for their first date. Each ride cost $5 and tickets cost $10 per person. They have $80 total to spend on tickets and rides.
Part A: Write an equation that models this situation.
Part B: Tony believes he and Mia can go on 12 rides each. Do you agree or disagree?
Part C: If Mia contributes an additional $20 to the total amount of money they could spend, how many more additional rides can Tony and Mia go on?
Answer:
A. 10+10+5x=80 or 20+5x=80
B. Disagree, After the pay for each person to get in the have 60 dollars left. Each ride costs 5 dollars. 60 divided by 5=12 and each of them would need a ticket, so they could only ride 6 rides/
C. 20/5=4=they could by an additional 4 tickets, each would need a ticket so they could ride 2 more rides each
Step-by-step explanation:
80-20=60
60/5=12
Answer:
Below are the answers
Step-by-step explanation:
Part A: The equation would be 5x - 20 = 80
Part B: I disagree, because each ride is $5 and if they both go on 12 that would host $120 and they only have $60 to spend. Since we took away $20 for tickets.
Part C: If Mia adds $20 dollars it would look like this 5x - 20 + 20 = 80 or
5x = 80 They would be able to go on 4 more additional rides. Because the original equation they can only go on 12 rides now they can go on 16 rides.

2. when we solve a quadratic equation, how many solutions should we always start out seeking? explain why when solving a quadratic equation in the form ax? bx c
For a quadratic equation, we start out seeking 2 solutions.
According to the statement
We have to find about the quadratic equation.
So, For this purpose, we know that the
Quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power
From the given information:
when we solve a quadratic equation, how many solutions should we always start out seeking.
Then
Here, we are required to search out out what number solutions to start out out seeking while solving a equation and also the condition for a quadratic graph not having zeros ( no x-intercepts).
Therefore, where X³ occurs in an equation, it's cubic and consequently has 3 solutions.
And, a quadratic can haven't any zeros ( no x intercepts) if the roots of the equation are complex numbers.
A quadratic is one which has the very best degree of its variable ( usually x) to be 2.
Consequently, after we solve a quadratic, one should start out seeking two (2) solutions.
This is so because, the quantity of solutions to begin out seeking corresponds with the very best power of the experimental variable, X.
Therefore, where X³ occurs in an equation, it's cubic and consequently has 3 solutions.
Therefore, where X¹ occurs in an equation, it's linear and consequently has 1 solution.
And, where X² occurs in an equation, it's quadratic and consequently has 2 solutions.
It is possible to possess a quadratic with no zeros (i.e no x-intercepts).
So, For a quadratic equation, we start out seeking 2 solutions.

3. the area of enlarged = 24 x 2= 48.
4. Yes. To enlarge a triangle with sloping sides, it is easiest to enlarge the base and the height. The base is 2 squares long and the height is 3 squares long. Multiply these lengths by the scale factor of 2 to find the enlarged shape.
**Polygon
explain: The scale factor is the ratio that determines the proportional relationship between the sides of similar figures. For the pairs of sides to be proportional to each other, they must have the same scale factor. In other words, similar figures have congruent angles and sides with the same scale factor.
