Point (2,6) is 2/3 of the way from A to B. If A has coordinates (-8, 6), what are the coordinates of B?
The coordinates of the point B are (-5, 6)
How to determine the coordinates of the point B?The given parameters are
A = (-8, 6)
Point = (2, 6)
Proportion = 2/3
Because the y coordinates are the same, we can make use of only the x coordinate
So, we have
Point = Proportion * (B - A)
This gives
2 = 2/3 * (B + 8)
Multiply through by 3/2
So, we have
3 = B + 8
Subtract 8 from both sides
B = -5
Hence, the coordinates of the point B are (-5, 6)

Some sales positions pay a commission only if sales exceed a sales
quota. The salesperson is rewarded only for having sales beyond an
expected amount. Joyce Doyle is a sales trainee. She is paid $1,550 per
month plus a commission of 7.5% on all sales of more than a $20,000
monthly quota. What is Joyce's total pay for a month in which her sales
totaled $22,650?
The sales on which Joyce earns commission is the sale beyond $20,000 which is $2,650. So the total pay for a month for Joyce in which her sales is $22,650 is $1748.75.
Joyce is paid $1,550 per month plus a commission of 7.5% on all sales of more than a $20,000 monthly quota. For the given month her sales is $22,650.
Percentage means a number or a ratio represented in the form of fractions of 100. It is represented using the percentage sign ‘%’. The abbreviations used to represent the percentage are ‘pct’ or ‘pc’. In other words, the percentage is defined as how much of one quantity is made by another quantity and it is evaluated in terms of 100.
Total pay of Joyce = Her pay per month + Commission that she gets
Commission she gets is on the sales beyond $20,000.
Here, commission is on $22,650 - $20,000 = $2,650
She gets 7.5% commission. So, her commission is 7.5% * $2,650
=> 75/1000 * $2,650 = $198.75
So, the total pay of Joyce is $1,550 + $198.75
=> $1748.75 for the month.

Maggie has a container in the shape of a right prism. the formula for its surface area is sa = ph 2b. solve for h. h = sa minus two times b over p h = sa plus two times b over p h = sa plus p over two times b h = sa minus p over two times b
The value of the height of the right prism is given by the formula, h = (SA - 2B) / P. It is gained by using the surface area of the right prism.
What is the right prism?
A right prism is a three-dimensional closed figure with 6 faces, 8 corners and 12 edges. It is called a right prism because, in this prism, the angle between the base and the sides is 90 degrees. All the faces of a right prism are rectangular, hence sometimes also called a right rectangular prism.
Calculation of h for the right prism
We know the surface area of the right prism is given by:
SA = Ph + 2B
Ph + 2B = SA
Subtracting 2B from both sides of the above equation, we have,
Ph + 2B - 2B = SA - 2B
Ph = SA - 2B
Dividing both sides of an equation by P, we get,
(Ph) / P = (SA - 2B) / P
h = (SA - 2B) / P
Hence, the value of h can be found using the formula, h = (SA - 2B) / P

A projectile with an initial velocity of 48 feet per second is launched from a building 190 feet tall. the path of the projectile is modeled using the equation h(t) = â€""16t2 48t 190.approximately when will the projectile hit the ground?1.5 seconds3.2 seconds5.3 seconds6.2 seconds
The time for the projectile to hit the ground from the given position is 1.5 s, which is obtained using the concept of time period and velocity of a projectile.
What is a projectile?
A projectile is defined as an object that has the force of gravity as the only force occurring on it. Acceleration in the projectile motion always acts vertically.
Calculation of the time taken by projectile to hit the ground
The given parameters:
The starting velocity of the projectile, u = 48 ft / s
Height of the projectile, h = 190 ft
Model of the projectile path, h(t) = - 16(t)2 + 48t + 190 —-- 1
When the projectile hits the ground, the final velocity, v = 0
differentiating equation 1 w.r.t t, we get,
(dh(t)) / (dt) = - 32t + 48
Putting dh(t) / dt = 0, we have,
- 32t + 48 = 0
32t = 48
t = 48 / 32
t = 1.5 s
Hence, the time taken by the projectile to hit the ground is 1.5 s.

1. How would you write the name of a segment differently than the name of a line. What symbols would you use?
Answer: A line and a line segment may sound quite similar however they are very different. A line, in short, is a line that never ends so it's infinite. It's the same for a line segment except at its end it is indicated by dots rather than arrows
2. How is constructing a perpendicular bisector similar to constructing an angle bisector? How is it different
Answer: A perpendicular bisector and an angle bisector are similar because they both require the need to find where two arcs meet. They are different because angle bisectors split into congruent angles meanwhile a perpendicular bisector splits into congruent segments.
3. Describe a process you would use to create the perpendicular bisector to a segment AB using only an unmarked straightedge and an unmarked compass.
Answer: The first step I will do will be to open the compass and stretch it to a width that will be greater than the length of AB. Then I would place one point of the compass onto the line's segments A, then I would move the compass and draw the arcs above and below the AB line. Next step I would do would be to remove the compass from point A and place it onto point B, then repeat the second step (drawing arcs above and below the line). Then lastly, I will use my straightedge and draw a line that will go vertically through where they connect.
1. A line segment can be written with just naming it by its end points and a bar above it while the name of a line requires an double-headed arrow mark above its name.
2. For constructing both a perpendicular and an angle bisector, we need to construct two arcs using a compass and their intersection point. A perpendicular bisector divided a line segment into two equal parts whereas an angle bisector divides an angle into two equal parts.
3. A perpendicular bisector can be drawn by drawing two arcs each above and below the line segment and joining using an straight edge.
1. A line and a line segment may sound quite similar however they are very different. A line, in short, is a line that never ends so it's infinite. It's the same for a line segment except at its end it is indicated by dots rather than arrows.
This difference can be seen in naming them too. A line segment is named using the initial and terminal points of the segment. Sometimes we put a 'bar' mark above its name. For example, [tex]\bar{AB}[/tex]
For a line of infinite length, it is named simply as 'line A' or 'line B' or sometimes put a double-headed arrow mark above its name.
2. A perpendicular bisector and an angle bisector are similar because they both require the need to find where two arcs meet. They are different because angle bisectors split into congruent angles meanwhile a perpendicular bisector splits into congruent segments.
Constructing a perpendicular bisector is similar in the sense that both are drawn using straight edge and compass and need to find the intersection point of the arcs. But they are different in their use as perpendicular bisector equally divides a line segment and an angle bisector equally divides an angle.
3. We have an unmarked straightedge and a compass. First put the compass at one end point A of the line. Then stretch the compass to a length more than half of the line segment AB to be bisected. In the next step, draw an arc above and one below the line. Next put the compass on the other end B of the line. Then repeat drawing two arcs, each above and below the line and also intersecting with the previous arcs. Finally join the two points got with a line cutting the line segment AB. This will be the perpendicular bisector of the line AB.

a store normally sells windows at $100 each. This week the store is offering one free window for each purchase of 4. Dave needs 7 windows and Doug needs 8. How much money will they save if they purchase together rather than separately?
They will save $100 if they purchase together rather than separately.
If this week, the store is offering one free window for each purchase of 4, then the price of 5 windows will be just equal to the price of 4.
1 window = $100
5 windows = 4 x $100 = $400
If
Dave needs 7 windows
Doug needs 8 windows
total they need together = 7+8 = 15 windows.
Buying at the offer of $400/5 windows,
they should buy 3 sets of 5 windows.
3 x 5 = 15
cost when bought together : 3 x $400
cost when bought together : $1200
If they bought separately,
Dave : 7 = 5 + 2
cost = $400 + 2($100)
cost = $600
Doug : 8 = 5 + 3
cost = $400 + 3($100)
cost = $700
cost when bought separately : $600 + $700
cost when bought separately : $1300
