Keys Per Minute recently hired Anne Bradford as a data entry clerk.Her starting rate of pay is $7.50 per hour and will increase to $8.00 per hour after 90 days. If her standard work week is 32 hours, what will her straight-time pay be 4 months from now ?
Answer:
$3904Step-by-step explanation:
From the question, since it will take 90 days that is 3 months for her hourly pay to increase to $8 per hour
we proceed to calculate her pay for the first 3 months
she works a total of 32 hours in a week
hence for three months, she would work 32*4*3= 384hours
therefore her pay for three months is= 7.5*384= $2880
Now the remaining one month her pay rate has been increased to $8 per hour
the number of hours in one month is 32*4= 128 hours
her pay would be 128*8= $1024
Her straight time pay for 4months is $2880+$1024 = $3904
A seat on a Ferris wheel is level with the center of the wheel. The diameter of the wheel is 210 feet (ft). If the wheel
rotates 45° counterclockwise and stops, how much does the height of the seat change?
Answer:
The change in the height of the seat of the Ferris wheel is a reduction in height of approximately 74.25 feet
Step-by-step explanation:
The given information are;
The position of the seat on the Ferris wheel = The center level of the wheel
The diameter of the Ferris wheel = 210 feet
The angle of rotation of the wheel = 45° counterclockwise
The height of a point on the Ferris wheel is given by the relation;
h = A·cos(b·x + c) + d
With regards to the question, we have;
h = The height of the seat of the Ferris wheel
A = The amplitude = 1/2 × The diameter of the wheel = 210/2 = 105 feet
360/b = The period
c = The phase shift = 90°
d = The mid line = 0
For a rotation of 45° counterclockwise or-45° clockwise, we have;
b·x = 45°, therefore;
h = 105 × cos(45° + 90°) + 0 = 105 × cos(135°) + 0
h = 105 × cos(135°) ≈ -74.25 feet
Therefore, the height of the seat of the Ferris wheel reduces by 74.246 feet.
In this exercise we have to know about rotation, therefore: the change in the height of the seat of the Ferris wheel is a reduction in height of approximately 74.25 feet.
The given information are:
The position of the seat on the Ferris wheel = The center level of the wheel. The diameter of the Ferris wheel = 210 feet The angle of rotation of the wheel = 45° counterclockwise
The height of a point on the Ferris wheel is given by the relation:
[tex]h = A*cos((b)(x) + c) + d[/tex]
With regards to the question, we have:
h = The height of the seat of the Ferris wheel
A = The amplitude = 1/2 × The diameter of the wheel = 210/2 = 105 feet
360/b = The period
c = The phase shift = 90°
d = The mid line = 0
For a rotation of 45° counterclockwise or-45° clockwise, we have;
[tex](b)(x) = 45\\h = 105 *cos(45 + 90) + 0 = 105 * cos(135) + 0\\h = 105 *cos(135) = -74.25 feet[/tex]
Therefore, the height of the seat of the Ferris wheel reduces by 74.246 feet.

Hope that helped!!!
Answer:
(A) and (C)
Step-by-step explanation:
To find equivalent expressions, we need to first find the value of the original, [tex]-3+(-5)[/tex]
Adding a negative is the same as subtracting a positive. So, it's equivalent to [tex]-3-5[/tex], which is [tex]-8[/tex].
Now we test all the other expression to see if they equal -8.
A:
[tex]-2 + (-6)\\\\-2-6\\\\-8[/tex]
So this works.
B:
[tex]1 + (-7)\\\\1 - 7\\\\-6[/tex]
So this doesn't work.
C:
[tex]5+(-13)\\\\5-13\\\\-8[/tex]
So this works.
D:
[tex]3+(-5)\\\\3-5\\\\-2[/tex]
So this doesn't work.
Hope this helped!

i want to know what g is
Answer:
Step-by-step explanation:
2(5-4g) + 3g - 11 = 5(g-3) - 12 - 3g (remove the parantheses)
10 - 8g + 3g - 11 = 5g - 15 - 12 -3g (Calculate and collect like terms)
-1 - 5g = 2g - 27 (move the terms)
-5g -2g = 27 + 1 (collect like terms and calculate)
-7g = -26 (divide both sides)
so G = 26/7
Answer:
G=27/6
Step-by-step explanation:
2(5−4g)+3g−11=5(g−3)−12−3g
(2)(5)+(2)(−4g)+3g+−11=(5)(g)+(5)(−3)+−12+−3g
10+−8g+3g+−11=5g+−15+−12+−3g
(−8g+3g)+(10+−11)=(5g+−3g)+(−15+−12)
−5g+−1=2g+−27
−5g−1=2g−27
Step 2: Subtract 2g from both sides.
−5g−1−2g=2g−27−2g
−7g−1=−27
Step 3: Add 1 to both sides.
−7g−1+1=−27+1
−7g=−26
Step 4: Divide both sides by -7.
-7g/-7=-26/-7
g=26/7

CD is a perpendicular bisector of . Which of the following could be the slopes of the two lines if plotted on a coordinate grid? A 1/2 and 2 B 4 and -4 C 1/3 and 1/3 D -7 and 1/7
Step-by-step explanation:
A is the correct answer of this question
The slopes that could have be plotted on the coordinate grid are -7 and 1/7
Before we determine the required slope of the two lines, we must understand that:
Two lines are perpendicular if the product of their slope is -1if the slope of a line is m, the slope of the line perpendicular will be -1/mSo, we choose the options that the product of the slopes equals -1
For option A:
[tex]product = 2 \times 1/2\\product = 1[/tex]
Hence option A is incorrect
For option B;
[tex]product = 4 \times - 4 = -16\\[/tex]
Hence option B is incorrect
For option C.
[tex]product = 1/3 \times 1/3\\product = 1/9[/tex]
Hence option C is incorrect
For option D;
[tex]product = -7 \times 1/7\\product = -1[/tex]
This shows that the slopes that could have been plotted on the coordinate grid are -7 and 1/7

Below is a cumulative relative frequency graph for the lengths, in minutes, of 200 songs
recorded by the Rolling Stones.
a. According to these data, the mean song length was 4.23 minutes, and the standard
deviation was 1.38 minutes. A music lover who wants to create a mix of songs wants to have 5 seconds of silence between songs, so he needs to add five seconds to the length of each song. He also wants to express the times in seconds, rather than minutes. Find the mean and standard deviation of the transformed data.
b. What are the mean and standard deviation of the z-scores of song lengths? Justify your answer.
Answer:
Adding 5 seconds would give
Mean= X`= 258.8 seconds
Standard Deviation=S= 82.8 seconds
The standard deviation remains the same.
Mean z= 0
Standard Deviation z= 1
Step-by-step explanation:
Mean= 4.23 minutes,
Standard Deviation= 1.38 minutes
He wants to add 5 seconds of silence between songs,
So we will convert these minutes into seconds
Mean= 4.23 minutes * 60= 253.8 seconds
Standard Deviation= 1.38 minutes* 60= 82.8 seconds
Adding 5 seconds would give
Mean= X`= 4.23 minutes * 60 +5 = 258.8 seconds
Standard Deviation=S= 1.38 minutes* 60= 82.8 seconds
The standard deviation remains the same.
b. Transforming into z- scores would give
Mean z= x`-u/s= 4.23-4.23/1.38= 0
Standard Deviation z= s/s= 1.38/1.38= 1
This is because changing into z- scores is simply a linear transformation.

Step-by-step explanation:
Liza draws an angle that measures 150 degrees.She then draws a ray that divides the angle into 2 equal parts
The given angle measures 150 degrees
She draw a ray that divides 150 degrees in to two equal angles
So we divide the angle 150 into two equal angles
[tex]\frac{150}{2} =75[/tex]
Two equal angles measures 75 degree each
So the measure of each smaller angle is 75 degrees
Answer:
75 degree
