1.) In Art class, Mrs. Lucia had 36 sheets of green paper and 42 sheets of
blue paper. If Mrs. Lucia wanted to give an equal number of each type of
paper, how many sheets of paper should each pupil get?
Answer:
Each pupil get 6 sheet
Step-by-step explanation:
Given:
Number of green sheet = 36
Number of blue sheet = 42
Find:
Common factor
Computation:
36 = 6 x 6
42 = 6 x 7
So, 6 is a common factor
Each pupil get 6 sheet
Each student should get 6 papers
The lowest common multiple is the smallest factor of a set of numbers.
The highest common factor is the biggest factor of a set of numbers.
A multiple of a number is a number that can divide another number without a remainder.
Factors of 36 =1, 2, 3, 4, 6, 9, 12, 18, and 36
Factors of 42 = 1, 2, 3, 6, 7, 14, 21, and 42.
The common factors of both numbers are : 1,2,3,6

Find the solution set for this inequality -2 x + 4 > -4x + 8.
Answer:
x > 2
Step-by-step explanation:
A line passes through the point. (4, -7) and has a slope of 5/2
Write an equation in slope-intercept form for this line.
t p = through point
s = slope
[tex]y - y(t \: p) = (s) \times ( \: x - x(t \: p) \: ) \\ [/tex]
[tex]y - ( - 7) = \frac{5}{2} \times (x - 4) \\ [/tex]
[tex]y + 7 = \frac{5}{2} \times (x - 4) \\ [/tex]
[tex]y + 7 = \frac{5}{2}x - \frac{5 \times 4}{2} \\ [/tex]
[tex]y +7 = \frac{5}{2}x - \frac{20}{2} \\ [/tex]
Subtract both sides -7
[tex]y = \frac{5}{2}x - 10 - 7 \\ [/tex]
[tex]y = \frac{5}{2}x - 17 \\ [/tex]
And we're done....

The equation in slope-intercept form is y= 5/2x - 17.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Slope = 5/2
and, point (4, -7).
Using Slope- intercept form
y = mx + b
y= 5/2x + b
As, the line passes through (4, -7)
-7 = 5/2(4) + b
-7 = 5(2) + b
-7 = 10 + b
b= -17
So, the Equation of line is y= 5/2x - 17.

In response to the increasing weight of airline passengers, the Federal Aviation Administration in 2003 told airlines to assume that passengers average 192 pounds in the summer, including clothing and carry-on baggage. But passengers vary, and the FAA did not specify a standard deviation. A reasonable standard deviation is 31 pounds. Weights are not Normally distributed, especially when the population includes both men and women, but they are not very non-Normal. A commuter plane carries 21 passengers. What is the approximate probability that the total weight of the passengers exceeds 4432 pounds
Answer:
The approximate probability that the total weight of the passengers exceeds 4432 pounds is 0.2709
Step-by-step explanation:
[tex]\mu = 192[/tex]
[tex]\sigma = 31[/tex]
No. of passengers = n = 21
We are supposed to find the approximate probability that the total weight of the passengers exceeds 4432 pounds
[tex]x = \frac{4432}{21} \sim 211[/tex]
[tex]Z=\frac{x-\mu}{\sigma}\\Z=\frac{211-192}{31}[/tex]
Z=0.612
refer z table
P(Z<211)=0.7291
P(Z>211)=P(Z>4432)=1-0.7291=0.2709
Hence the approximate probability that the total weight of the passengers exceeds 4432 pounds is 0.2709

Answer:
4mm
Step-by-step explanation:
The ratio of the two congruent shapes are 2.5:1
15 : 6 = 2.5 : 1
15/6 = 2.5
5 : 2 = 2.5 : 1
5/2 = 2.5
Therefore, 10 : x = 2.5 : 1
10/x = 2.5
x = 4
Answer: 15, 2, 6, and 5

A coin is tossed and -sided die numbered 1 through is rolled. Find the probability of tossing a and then rolling a number greater than .
Complete question :
A coin is tossed and a die is rolled. Find the probability of tossing a tail and then rolling a number greater than 2.
Answer : 1/3
Step-by-step explanation:
For a coin :
Sample space = (T, H)
Probability = required outcome / Total possible outcomes
Probability of tail, p(T) = 1 / 2 = 0.5
For a fair die:
Sample space = (1, 2, 3, 4, 5, 6)
Required outcome = number greater than 2 = (3, 4, 5, 6) = 4
P(number greater than 2) = 4/6 = 2/ 3
Hence, probability of a tail, then a number greater than 2 :
(1/2 * 2/3) = 2 /6 = 1/3

The equation y = 2.50x determines the total cost, y, of buying carnival tickets
Step-by-step explanation:
The given equation or expression is used to determine the total cost of buying carnival tickets.
the total cost is y
Also from the expression the cost of a ticket is $2.5
and x represents the number of tickets
now say x=5, that is 5 tickets, then the cost of buying the 5 tickets is given as
y=2.5(5)
y=12.5
Hence the cost of 5 tickets is $12.5

100 points please help ! What is the name of the line of reflection for the pair of figures
Answer:
Hey!
I think the line must be LINE R
Step-by-step explanation:
As you can see it must be the Line of Reflection for both figures because it is EQUIDISTANT (equal distance from the 2 shapes). It runs PARALLEL in angle to the shapes too...
It can't be Line P because the line does not produce equal shapes on either side of it...
It can't be Line Q because it only provides the reflection result on one of the shapes, not BOTH...
So your answer is Line R

If m<7 is 2x + 30 and m<28 is 3x - 10, find the
following:
Answer:
x = 32
m∠7 = 94
m∠8 = 86
m∠3 = 94
Step-by-step explanation:
(2x + 30) + (3x - 10) = 180
5x + 20 = 180
5x = 160
x = 32
m∠7 = 2(32) + 30 = 94
m∠8 = 3(32) - 10 = 86
or
m∠8 = 180 - 94 = 86
m∠3 ≈ m∠7 (corresponding angles)
