Answer:
Alex is reading faster by 5 more pages per hour.
Step-by-step explanation:
Alex's rate of reading is 1/2 pages per minute, or 1 page every 2 minutes. To convert his rate to pages per hour, we can divide 60 (minutes in an hour) by 2 (minutes it takes Alex to read a page) which is equal to 30 (pages read in an hour). Therefore, Alex is reading at 30 pages an hour and reading 5 more pages an hour than Sammie.
A rock climber begins climbing at an altitude of 120 meters. She climbs at a rate of 50 meters per hour. Which equation can be used to find the altitude of the rock climber, y, after x hours?
Answer:
y=50x+120
Step-by-step explanation:
y is the ending altitude
x is the number of hours the climber has climbed
put 50 before x because that how fast the climber is climbing
then 120 is your y intercept
Round your answer to the nearest tenth.
Answer:
The value of MB = 8.4
Step-by-step explanation:
We know that the point of intersection of the Medians of a triangle is called the centroid of a triangle.
Thus,
For the given triangle ΔJKL,
The point M is the centroid of the triangle.We also know that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.
Also, each Median is split into two parts such that the longer part is 2 times the length of the smaller part.
In our case,
The median KB is split into two parts such that the longer part KM is 2 times the length of the smaller part MB.
i.e.
KM = 2 MB
Given KM = 16.8
so substitute KM = 16.8 in the equation KM = 2 MB
16.8 = 2 MB
MB = 16.8/2
MB = 8.4
Therefore, the value of MB = 8.4

Michael reads 12 pages of a book in 18 minutes, 8 pages in 12 minutes, and 20 pages in 30 minutes. I’d this a proportional relationship? What does it represent? Write an equation to represent this situation.
Answer:
Y= 1.5x
Step-by-step explanation:
What you would do is divide all of the minutes by the amount of pages to find how long for each rate for one page. (ex. 18/12, Michael reads 1 page in 1.5 minutes. 12/8, Michael reads 1 page in 1.5 minutes. 30/20, Michael reads one page in 1.5 minutes) Therefore, yes it is proportional, and the equation is y=1.5x (there is no y intercept)

A. 13
B. 24
C. 6
D. 34
Answer:
A. 13.
Step-by-step explanation:
x + 9 = 2(3x - 38)
X + 9 = 6X - 76
85 = 5x
x = 85/5
x = 17
So RS = 3(17) - 38
= 51 - 38
= 13

For the denominator to become 100, we multiply 2 to the numerator and denominator:
23/50 = (23 * 2)/(50 * 2) = 46/100 = 46%.
Answer:
[tex] \frac{23}{50} = \frac{23 \times 2}{50 \times 2} = \frac{46}{100} = 46\%[/tex]
46% is the right answer.

In ARST, RS – TR and mZT = 15°. Find mZS.
Answer:
54
Step-by-step explanation:
a solution for y = x + 2
There is an infinite number of solutions.
Y = x + 2
You could replace Y with 4 and X with Y-2 (which is 2 in this case. 4-2=2).
The result would look like this:
4 = 2 + 2
or
Y = x + 2
Y = 4
x = 2

[tex]x(x-5)-3(x-5)=0[/tex]
[tex](x-5)(x-3)=0[/tex]
[tex]x=5,3[/tex]
Hope its Helpful!Answer: x = -3, -5
Step-by-step explanation:
Solve by Factoring
x^2 + 8x + 15 = 0
Factor x2 + 8x + 15 using the AC method.
Consider the form x2 + bx + c. Find a pair of i ntegers whose product is c and whose sum is b. In this case, whose product is 15 and whose sum is 8.
3, 5
Write the factored form using these integers.
(x + 3) (x + 5) = 0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x + 3 = 0
x + 5 = 0
Set x + 3 equal to 0 and solve for x.
Set x + 3 equal to 0.
x + 3 = 0
Subtract 3 from both sides of the equation.
x = −3
Set x + 5 equal to 0 and solve for x.
Set x + 5 equal to 0.
x + 5 = 0
Subtract 5 from both sides of the equation.
x = −5
The final solution is all the values that make (x + 3) (x + 5) = 0 true.
x = −3, −5

Answer:
The medians of all three teams can show the overall skill level of the teams. For example, the medians only vary between 47 and 48. This can show that most team members have around the same experience (since they have around the same median). The red team was the best in terms of time, but they don't vary much from their opposing teams.
Step-by-step explanation:

. Christian made $138,000 as a Physician Assistant. Social Security tax is to a maximum income of $128,400. The Medicare tax is 1.45% and the Social Security tax rate is 6.2%. How much did Christian pay in FICA taxes?
Answer:
Total money made as a physician = $138,000
Medicare tax = 1.45% of $138,000
= 1.45/100 * $138,000 = $2001
security tax = 6.2 %of $138,000
= 6.2/100 * $138,000 = $8556
= $138,000 - ($2001 + $8556)
$138,000 - $10557
= $127,443 is paid by Christian in FICA taxes

Easy area problem
Need fast
Answer:
48 ft²
Step-by-step explanation:
The area of the green shaded part will be :
Area of the entire rectangle green shape assumed complete minus the area of the removed parts{ small rectangle + triangle }
Area of the entire rectangle green shape assumed complete
Area= length * width
A= l*w
A= 5ft * 12 ft = 60 ft²
Area of small rectangle removed part
2 * 3 = 6 ft²
Area of the triangle removed
A= 1/2 * b * h
A= 1/2 * 3 * 4
A= 6 ft²
Area of the outdoor carpet needed for the hole
60-{6+6}
60 -12 = 48 ft²

Answer:
153.9 in²
Step-by-step explanation:
Using the formula: A = π r²
Where r = the radius and π is 3.14.
The radius is the diameter divided by 2.
14 divided by 2 is 7.
Plug in 7 into the formula:
A = π 7²
7² is 49.
49 times π is equal to 153.86.
Rounding this up to the nearest tenth, you'll get 153.9
