Given directed line segment cd, if point e divides cd three-fourths of the way from c to d, find the coordinates of e.
The coordinates of point E is (-2, -1.5)
How to determine the coordinates of point E?
see in the file attached below
The given parameters are
C = (1, 6)
D = (-3, -4)
The ratio 3/4 can be represented as:
m : n = 3 : 1
So, the coordinate of point E is
E = 1/(m + n) * (mx2 + nx1, my2 + ny1)
So, we have:
E = 1/(3 + 1) * (3 * -3 + 1 * 1, 3 * -4 + 1 * 6)
Evaluate
E = 1/(4) * (-8, -6)
This gives
E = (-2, -1.5)
Hence, the coordinates of point E is (-2, -1.5 )

Jacob signs up to work for 2 5/8 hours at the school carnival. If each work shift is 3/4 hour, how many shifts will Jacob work
3 full shifts of 3/4 hour and 1 half shift of 3/4 hour
Shift work is an employment strategy intended to utilize or give service during each of the seven days of the week's full 24 hours. The day is often divided into shifts, predetermined times when various groups of workers carry out their tasks.
Total work hours = 2.625 hours
Each shift = 0.75 hr
Number of shifts = Total work hours / Each shift
= 2.625 / 0.75
= 3.5
Therefore, He worked three full shifts of three hours each and one half-shift of three hours.

If a number is greater than -500, then the number is greater than 500.
Determine the truth value of the conditional statement. Explain.
The truth value of the conditional statement is false
How to determine the truth value of the conditional statement?
The conditional statement is given as
“If a number is greater than -500, then the number is greater than 500.”
The above conditional statement is false
This is because not all numbers greater than -500 are greater than 500
for example 450 is greater than -500, but less than 500 that is the number between -500 and 500 will not satisfy the above statement.
Hence, the truth value of the conditional statement is false

Answer: A
Step-by-step explanation:
Angles on a straight line must add up to 180 so angle BCA is 180-132=48
Because the triangle BAC is an isosoles angle BCA and ABC must be the same so 48
We can now use the angle on a straight line rule to figure out angle DBA 180-48=132
We know that triangle DBA is an isosoles trianlge so and x and DAB must be the same and both be x, and we know that angles in a triangle add up to 180 so the equation can be written as:
180=2x+132
48=2x

passing through (7, y) and (-1,-3) has a slope of 3/4.
Answer: y=3
Step-by-step explanation:
Slope formula: m=(y2-y1)/(x2-x1)
3/4=(y2-y)/(x2-x1)
3/4=(-3-y)/(-1-7)
3/4=(-3-y)/(-8)
(3/4=(-3-y)/(-8))*(-1) ==> Negate the equation to remove the negative denominator

The total number of digits mentioned on the number plate is 4.
The first place is to be filled by letter.
We know that there are total 26 letter. So, there are total 26 possible ways in which the place is filled.
Now, the second place is also to be filled by the letter, but now the letter left are 25. Thus, possible fillings is by 25 letter.
The third position is to be filled by number; there are 10 number (0 - 9) by which the position can be filled.
The fourth position is also to be filled by the number; but now the numbers left are 9.

in a balloon it was notices that the pressure, in atmosphere (atm), was inversely proportional to the square root of the height, in metres. when the balloon was at the height of 25m,tge pressure was 1.44atm. what was the pressure at a height of 9m?
It was discovered that the pressure in atmospheres (atm), when applied to a balloon, was inversely related to the height in meters, squared root. The pressure was 1.44 atm when the balloon was 25 meters height in the air. What was the pressure like at a 9-meter height?
The pressure is 2.4 atm when the height is 9m.
Inversely proportion means when one variable is directly proportional to the reciprocal of the other, there is an inverse fluctuation between the two variables. In other words, the two variables' product has a fixed value. Therefore, as one variable rises, the other falls.
Here, We take pressure of atmosphere as P and the height of the balloon as H.
Given that, The pressure of atmosphere was inversely proportional to the square root of the height.
We write this as [tex]P[/tex]∝[tex]\frac{1}{\sqrt{H} }[/tex].
Taking constant of the proportionality as k.
[tex]P[/tex]=[tex]\frac{k}{\sqrt{H} }[/tex].
We have, The pressure was 1.44 atm when the balloon was 25 meters height in the air.
P=1.44 and H=25
[tex]1.44=\frac{k}{\sqrt{25} }[/tex].
[tex]1.44=\frac{k}{5}[/tex]
[tex]k=5\times1.44[/tex]

Levi must score 220 in Exam B in order to do equivalently well as he did in Exam A
How well must Levi score on Exam B in order to do equivalently well as he did on Exam A?The given parameters are:
Exam A
Score = 710
Mean = 700
Standard deviation = 25
Exam B
Mean = 200
Standard deviation = 50
The z-score is calculated as
z = (Score - Mean)/Standard deviation
For exam A, we have
z = (710 - 700)/25
z = 0.4
For exam B, we have
z = (Score - 200)/50
Substitute z = 0.4 in z = (Score - 200)/50
0.4 = (Score - 200)/50
This gives
Score - 200 = 20
Add 200 to both sides
Score = 220

slope intercept form of -5/6x+4
The slope of equation y = -5/6 x + 4 is -5/6 and the slope-intercept form of -5/6x+4 is y = -5/6 x + 4
The slope of a function y = f(x) is given by a formula
slope = y2-y1 / x2- x1
where ( x1 , y1) and (x2, y2) are coordinates of any two points on the line of graph representing y = f(x)
Or we can simply use the slope-intercept form
y = mx+ c
where m is the slope of the given equation and c is the constant
so, in the given equation y = -5/6 x + 4
slope of the equation is -5/6
Hence, The slope of equation y = -5/6 x + 4 simply is -5/6 and the slope intercept form of -5/6x+4 is y = -5/6 x + 4
When you know the slope of the line to be investigated and the point given is also the y intercept, you can utilize the slope intercept formula y = mx + b. (0, b). The y value of the y intercept point is represented by b in the formula.
