Answer:
Step-by-step explanation:
L=2W-5 and P=2(L+W) is the system
Substituting L=2W-5 into P=2(L+W) gives you
2(2W-5+W)=P=60
2(3W-5)=60
3W-5=30
3W=35
W=35/3, L=2W-5
L=55/3

The data shows the speed, in miles per hour, of motorists on a stretch of
road.
42, 35, 44, 31, 47, 41, 36, 34, 39, 18, 37, 32, 37, 33, 43, 41, 44, 47, 46
18 miles per hour is an outlier.
0 47 miles per hour is an outlier.
The outlier decreases the mean speed.
The outlier decreases the median speed.
Answer:
18 miles per hour is an outlier
the outlier decreases the mean speed
Step-by-step explanation:
the low number of 18 is way different from the other numbers being in the 30's and 40's
this 18 will bring the mean of all the numbers own because it is a smaller number.
Answer:
Step-by-step explanation:
Mean:44
Median:31
Mode:47

Each wheel on the train has a diameter of 1.8 m.
Work out the number of complete turns each wheel makes in travelling the 6.5 km..
Answer: 1150 turns
Step-by-step explanation: radius of wheel is 0,9 m
In one turn wheel moves 2·pi·0,9 m = 5,652 m
You divide 6500 m : 6,652 m = 1150
The number of complete turns each wheel makes in travelling the 6.5 km is 1150 turns
What is a circle?A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.
We know that circumference of the circle that has a radius of r is defined as the product of diameter to the pie value.
The circumference of the circle = 2πr
WE have been given the radius of wheel is 0.9 m
In one turn wheel moves 2πr
= 2 x π x 0.9 m
= 5.652 m
Now we have to divide 6500 m : 6.652 m
= 1150

~AH1807Just by looking at the question x + 6 + 2x = 2x + 6 + 4 so what does x equal and why?
I need help fast!
Answer:
x = 4
Step-by-step explanation:
x + 6 +2x = 2x + 6 + 4
combine like terms:
3x + 6 = 2x + 6 + 4
add numbers:
3x + 6 = 2x + 10
subtract 6 on both sides:
3x + 6 - 6 = 2x + 10 - 6
3x = 2x + 4
subtract 2x from both sides:
3x - 2x = 2x - 2x + 4
x = 4
short explanation:
if you look at the equation, both sides have 6 and 2x which would cancel each other out. That would leave x = 4
Compare the rules of two games.
Game A: Two six-sided dice are thrown. The numbers on the dice determine which player gets a point.
Player 1 gets a point if the product of the numbers on the dice is even. Player 2 gets a point if the
product is odd.
Game B: Two six-sided dice are thrown. The numbers on the dice determine which player gets a point.
Player 1 gets a point if the sum of the numbers on the dice is even. Player 2 gets a point if the sum is
odd.

Zander read 13 3/4pages in 1/4 of an hour. Sydney read 43 1/3 pages in 2/3 of an hour. At these rates, would Zander or Sydney read more pages in 1 hour?
Answer:
At these rates Sydney read 10 pages per hour more than Zander.
Step-by-step explanation:
Zander read [tex]13\frac{3}{4}[/tex] pages in [tex]\frac{1}{4}[/tex] of an hour.
Therefore, pages read by Zander in 1 hour = [tex]\frac{\text{Total pages read}}{\text{Total time taken}}[/tex]
= [tex]\frac{13\frac{3}{4}}{\frac{1}{4}}[/tex]
= [tex]\frac{55}{4}\times \frac{4}{1}[/tex]
= 55 pages per hour
Sydney read [tex]43\frac{1}{3}[/tex] pages in [tex]\frac{2}{3}[/tex] of an hours.
Pages read by Sydney in 1 hour = [tex]\frac{43\frac{1}{3}}{\frac{2}{3} }[/tex]
= [tex]\frac{130}{3}\times \frac{3}{2}[/tex]
= 65 pages per hour
Therefore, number of pages read more by Sydney as compared to Zander,
= 65 - 55
= 10 pages per hour
At these rates Sydney read 10 pages per hour more than Zander.

Demetri's parents begin saving for his college funds when he was 10 years old. They invest $5,000 in a CD that earns 1.2% interest compounded annually. What will the balance in the CD be when he turns 18?
Answer:
Yes, the CD earns over $500 in interest over 8 years.
Step-by-step explanation:
So basically the money was invested for when he was 10 to 18 so 8 years and when there is compound interest the value always increase so the working out u would do is times the original amount by 1.012 to the power of 8 And it should be more that the amount u need. I hope that makes sense. ¯\_(ツ)_/¯

Mariah is replacing the water heater in her home and is considering three different models. One of the things she is comparing is
the volume of the cylindrical storage tank in each water heater. The dimensions of the storage tanks, in inches, are as follows.
• Water Heater X: r= 8.5 and h = 48
• Water Heater Y: r= 9.5 and h = 44
• Water Heater Z: r= 10.5 and h = 32
Which statement is true?
OA. Water heater Y has the storage tank with the greatest volume.
B. Water heater X has the storage tank with the greatest volume.
OC
The storage tanks in all three water heaters have the same volume.
OD
Water heater Z has the storage tank with the greatest volume.
Answer:
A
Step-by-step explanation:
The volume of a Cylinder is [tex]\pi \\[/tex]*r^2 * h
In this problem I will use 3.14 as pi because it is easier to type
Water Tank X: 8.5*8.5*3.14*48=10,889.52
Water Tank Y: 9.5*9.5 *3.14*44=12,469.94
Water Tank Z: 10.5*10.5*3.14*32=11,077.92
So, A is correct.
