CINDY IS A HOSTESS AT A COUNTRY CLUB
ON THE WEEKENDS. SHE WORKED 3 Ž HOURS
ON FRIDAY NIGHT AND 5 HOURS ON
SATURDAY. IF SHE EARNED A TOTAL OF
$105 THIS WEEKEND AND IS PAID THE SAME
AMOUNT EACH HOUR SHE WORKS, HOW MUCH
DOES SHE EARN PER HOUR?
Answer and Step-by-step explanation:
Add together the hours, then divide the amount earned by the total amount of hours.
3 + 5 = 8
105 ÷ 8 = $13.125 (which would round up to 13.13) [About $13.13] is earned per hour.

a pair of jeans originally cost $140 and are now on sale for 65% off. what is the sale price of the jeans
Answer:
$49
Step-by-step explanation:
Method 1:
100% - 65% = 35%
[tex]\frac{y}{140}: \frac{35}{100}[/tex]
y · 100 = 35 · 140
100y = 4900
100y ÷ 100 = 4900 ÷ 100
y = 49
Method 2:
[tex]\frac{y}{140}: \frac{65}{100}[/tex]
y · 100 = 65 · 140
100y = 9100
100y ÷ 100 = 9100 ÷ 100
y = 91
$140 - $91 = $49
AYUDAAAAAAAA POR FAVORRRRR
so sorry not sure how to do this ! :c

3. A pupil left home for school at a speed of
5 km/h and returned at a speed of 4 km/h
The whole journey took 5 h 24 min.
How far is the school from home, in
kilometres
A 9
B. 12
C. 24
D. 27
Answer:
12 km
Step-by-step explanation:
5h 24min = 5.4 hrtime = distance / speed--------------------------------
time out + time back = total time
d/5 + d/4 = 5.4
multiply both sides by 20 to clear the fractions
4d + 5d = 108
9d = 108
Divide both sides by 9
d = 12 km
What is the quotient of 2/3 and 2/9?

What is the slope of the graph?
Answer:
-4
Step-by-step explanation:
Slope can be found with [tex]\frac{y2-y1}{x2-x1}[/tex]
Pick two points on the graph that the line runs through
(-2, 4) will fill the values of x1 and y1, and (-1, 0) will fill the values of x2 and y2
Insert the coordinates into the formula
[tex]\frac{0-4}{(-1)-(-2)}[/tex]
[tex]\frac{-4}{-1+2}[/tex]
[tex]\frac{-4}{1}[/tex]
Therefore the slope is -4

Gather information from relevant source and write about the he Earth's moon .
1000 words
Answer:
The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period of 29.5 days, the amount of visible surface illuminated by the Sun varies from none up to 100%, resulting in lunar phases that form the basis for the months of a lunar calendar. The Moon is tidally locked to Earth, which means that the length of a full rotation of the Moon on its own axis causes its same side (the near side) to always face Earth, and the somewhat longer lunar day is the same as the synodic period. That said, 59% of the total lunar surface can be seen from Earth through shifts in perspective due to libration.[17]
The most widely accepted origin explanation posits that the Moon formed about 4.51 billion years ago, not long after Earth, out of the debris from a giant impact between the planet and a hypothesized Mars-sized body called Theia. It then receded to a wider orbit because of tidal interaction with the Earth. The near side of the Moon is marked by dark volcanic maria ("seas"), which fill the spaces between bright ancient crustal highlands and prominent impact craters. Most of the large impact basins and mare surfaces were in place by the end of the Imbrian period, some three billion years ago. The lunar surface is relatively non-reflective, with a reflectance just slightly brighter than that of worn asphalt. However, because it has a large angular diameter, the full moon is the brightest celestial object in the night sky. The Moon's apparent size is nearly the same as that of the Sun, allowing it to cover the Sun almost completely during a total solar eclipse.
A store offered a buy one get one free sale for a popular shirt. The manager noticed that 35% of consumers bought a red shirt, 25% a blue, and 40% a green. Assume all consumers bought either two shirts or none at all, but no consumer buys two shirts of the same color. How many consumers did not buy any of these shirts
Answer:
50%
Step-by-step explanation:
Let X = Green and red
Y = Red and blue
Z = Green and blue
( Buy green or red or blue )
⇒ (x + y) + (y + z) + (z + y) = 25 + 40 + 25
⇒ 2( x + y + z) = 100
∴ x + y + z = 50
Buy at least one shirt = 50%
So, did not buy any shirt = 100 - 50
= 50%

The table below shows the probability distribution of student ages in a high school with 1500 students. What is the expected value for the age of a randomly chosen student? Age 13 14 15 16 17 18 Probability 0.01 0.27 0.30 0.25 0.16 0.01 O A. 15.38 B. 15.31 о O C. 15.50 O D. 15.35 SUBMIT
Answer:
15.31
Step-by-step explanation:
The expected value, E(X) is given by :
E(X) = Σx*p(x)
From the table above :
E(X) = (13 * 0.01) + (14 * 0.27) + (15 * 0.30) + (16 * 0.25) + (17 * 0.16) + (18 * 0.01)
E(X) = 15.31

Find the scale factor of ABC to MNO.
Answer:
6/5
Step-by-step explanation:
The scale factor can be obtained by simply finding the ratio of the lenght of the side of one shape to the length of the same side of the other shape.
Thus, we can obtain the scale factor that will take us from △ABC to △MNO as illustrated below:
Original Length BC = 15 in
New Length NO = 18 in
Scale factor =?
Scale factor = New lenght NO / Original length BC
Scale factor = 18 / 15
Scale factor = 6/5
Therefore, the scale factor that will take us from △ABC to △MNO is 6/5.

what is the answer to this im having trouble figuring it out
Answer:
option c - 9.9
Step-by-step explanation:
The angle between a tangent to a circle and the radius at the point of contact is 90 degree.
So the triangle is a right angle triangle.
The side opposite the 90°, is the hypotenuse.
Using Pythagoras theorem:
[tex]16.5^2 = 13.2^2 + x^2\\\\16.5^2 - 13.2^2 = x^2\\\\x^2 = 272.25 - 174.24 = 98.01\\\\x = \sqrt{98.01} = 9.9[/tex]

Before you factor you should check what two things?
Answer:
I put all the steps to factoring, hopefully this helps! ^^
Step-by-step explanation:
-Check for common factors. If the terms have common factors, then factor out the greatest common factor (GCF) and look at the resulting polynomial factors to factor further.
-Determine the number of terms in the polynomial.
-Look for factors that can be factored further.
-Check by multiplying.

Select all true statements about the data
DA Jasmine spent more minutes doing homework during the month of April.
B
The mean value
greater for the month of April
C. The median value is greater for the month of April
D. Based on the interquartile range, there is greater variability for the month of April
Answer:
Option A,B,C and D is correct
Step-by-step explanation:
As we can see , the data set for April month has longer time duration taken for completing homework as compared to the time taken during the month of April. Hence, option A is correct.
Option B is also correct because most of the instance of time taken for doing homework is greater for month of April as compared to the month of March
Median value for the month of march = 25 and median value for the month of April is (30+35)/2 = 32.5. Hence, Option C is correct
There is greater variability for the month of April. Hence, option D is correct

2:3
Question isnt well formatted :
Answer:
1 : 6
Step-by-step explanation:
Given the question :
3x = 1/2y
3x = y/2
Multiply both sides by 2
3x * 2 = y/2 * 2
6x = y
This can be interpreted as :
y = 6 times the value of x
x = y/6
x : y
1 : 6
