Answer:
D. -15/4
Step-by-step explanation:
Using PEMDAS, I know that I have to begin by calculating the expression inside the parentheses: -25 divided by 1/3. Dividing by 1/3 is the same as multiplying by 3. -25 multiplied by 3 is equal to -75. Then, working from right to left, we multiply that by 1/5. 1/5 of -75 is -15. Now, we take that -15 and multiply it by 1/4. This is equivalent to -15/4.

A salesperson works 40 hours per week at a job where she has two options for being paid. Option A is an hourly wage of $22. Option B is a commission rate of 8% on weekly sales. How much does she need to sell this week to earn the same amount with the two options?
PLEASE HELP
Answer:
We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of $25. Option B is a commission rate of 8% on weekly sales.
First of all we will find amount earned by salesperson with option A.
The salespersons earns $1000 through option A.
Let x be the amount of weekly sales.
8% of x should be equal to 1000 for salesman to earn the same amount with the two options.
Therefore, the salesman needs to make a weekly sales of $12,500 to earn the same amount with two options.We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid.

An elevator rises steadily up a skyscraper. After 4 s it is 33 m above the ground, 2 s later it is 47 m above the ground. Which equation models its position, y, with respect to time, x?
Answer:
The 2nd motion eqn.
S = ut + 1/2gt²
where, u is the initial speed of the elevator
S = position
and t = x
y = ux + 1/2gx²
y = 1/2gx² + ux
since the elevator started at 0 as initial speed(that is at rest)
y = 1/2gx² + 0
y = 1/2gx² is the eqn

what is the area of a triangle with a base of 6.5 inches and a height of 6 inches?
Answer:
Step-by-step explanation:
Hi there!
Given;
base (b) = 6.5 inches
height (h) = 8 inches
Now;
[tex]area= \frac{1}{2}*b*h[/tex]
[tex]area (a)=\frac{1}{2}*6.5*8[/tex]
area = 52/2
Therefore, the area of the triangle is 26 [tex]inches^{2}[/tex].

What is the image of the point (7,4) after a rotation of 90° counterclockwise about
the origin?
Answer:
When rotating a point 90 degrees counterclockwise about the origin the point (7,4) becomes (-4,7).
Step-by-step explanation:
In other words, just switch x and y and make y negative.
The point will be inverted when (7,4) is rotated 90° counterclockwise i.e., the new point will be (4,7).
It is given that a point (7,4) is rotated 90° counterclockwise about origin.
We have to find the new point after rotation.
What do you mean by rotation counterclockwise ?
If something is moving counterclockwise that meant it is moving in the opposite direction to the direction in which the hands of a clock move.
As per the question ;
A point (7,4) is rotated of 90° counterclockwise about origin.
Let's assume (7,4) = (x , y)
If we rotate it 90°counterclockwise ; then the point will be inverted ; i.e.,
(x , y ) ⇒ ( y , x)
So ;
( 7 , 4 ) = ( 4 , 7 )
So ;
The new point will be ;
= ( 4 , 7 )
Thus , the point will be inverted when (7,4) is rotated 90° counterclockwise i.e., the new point will be (4,7).
