Answer:1/2,-3/2,-3/8
Step-by-step explanation:
The slope of the lines are -3/8, 1/2 and -7/2 respectively.
A linear equation is given by:
y = mx + b
Where y, x are variables, m is the slope of the line and b is the y intercept.
1) The slope (m) of the line that goes through (0,5) and (8,2). is:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{2-5}{8-0}\\\\m=-\frac{3}{8}[/tex]
2) The slope (m) of the line that goes through (2, -1) and (6,1). is:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{1-(-1)}{6-2}\\\\m=\frac{1}{2}[/tex]
3) The slope (m) of the line that goes through (-3, -2) and (-1, -5). is:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-5-2}{-1-(-3)}\\\\m=-\frac{7}{2}[/tex]
The slope of the lines are -3/8, 1/2 and -7/2 respectively.

Mary bought a car priced at $23,500. If the value of the car decreases every year by 9%, approximately what will be the value of the car after 10 years?
Answer:
$4626.548
Step-by-step explanation:
Given that :
Cost of car = $23,500
Value of car decreases by 9% every year
Value of car after 10 years =?
Using the formula :
A = p(1 + r/n)^nt
A = final amount
P = cost of car = principal
r = Depreciation = - 15%
t = number of years
A = 23500(1 + - 0.15/1)^10
A = 23500(0.85)^10
A = $4626.548

1. Dennis made a 500 km trip in five hours. For the first two hours, Dennis had an average speed of 150 km/h. For the last two hours, Dennis had an average speed of 100 km/h. Which of the following is true about Dennis' trip? (25 Points) Dennis must have maintained a constant velocity throughout his trip. Dennis must have maintained a constant speed throughout his trip. O Dennis must have stopped for an hour in the middle of this trip Wich statemeent correctly discribes the locaton and Dennis must have driven without stopping during his trip
Answer:
The correct option is;
Dennis must have stopped for an hour in the middle of this trip
Step-by-step explanation:
The given parameters are;
The distance Dennis covered in 5 hours = 500 km
Dennis's average speed in the first two hours = 150 km/h
Dennis's average speed in the last two hours = 100 km/h
Therefore;
Dennis traveled 150 km/h × 2 h = 300 km in the first two hours
Dennis traveled 100 km/h × 2 h = 200 km in the last two hours
Which gives, Dennis traveled 300 km + 200 km in 2h + 2h = 4h
Therefore, Dennis traveled 500 km in 4 hours and Dennis must have stopped for an hour in the middle of this trip.

Sharon drives 1/3 of the total distance to big bend on the first day. On the second day, she travels 1/3 of the total distance in the morning and 1/6 of the total distance in the afternoon. How much of the total distance has sharon driven by the end of the day?
Answer:
5/6
Step-by-step explanation:
Given that :
Fraction of total distance driven on first day = 1/3
Second day :
Fraction driven in the morning = 1/3
Fraction driven in the afternoon = 1/6
Total distance driven by the end of the day :
1/3 + 1/3 + 1/6
Take the L. C. M
(2 + 2 + 1) / 6
= 5 /6
5/6 of the total distance

How many times will you roll a number less than 4 on a number cube if you rolled it 250 times ?
A) 100
B) 90
C) 125
D) 85
Answer:
C. 125
Step-by-step explanation:
The ratio for one time is 3:6. It is 3:6 because there are 3 numbers less than 4 on a number cube. You can now compare the two ratios.
3:6 = x/250.
This is a ratio, so both numbers would have to be multiplied by the same number. 6 * 41 = 250.
3 * 41 = 123.
(41 was rounded from 41.6666667. This is why it comes out to 123.)
Question 14
A company paid $391 for 15 bushes and 8 bonsai trees. They had to purchase 9 more bushes and 5 more bonsai trees for $241. What is the cost of each bush and bonsai tree? Enter your answers in the
boxes below.
Bushes:
Bonsai Tree:
Answer:
The cost of each bushes is $9.00
The cost of each bonsai trees is $32.00
Step-by-step explanation:
The given parameters are
The amount the company paid for 15 bushes and 8 bonsai trees = $391
The amount for which the company purchased 9 more bushes and 5 more bonsai trees = $241
Let x represent the cost of each bushes and let y represent the cost of each Bonsai Trees, we have;
15 × x + 8 × y = 391...(1)
9 × x + 5 × y = 241...(2)
We make y the subject of both equations to get;
For equation (1), we have;
15·x + 8·y = 391
15·x + 8·y = 391
8·y = 391 - 15·x
y = 391/8 - 15/8·x
For equation (2), we have;
9 × x + 5 × y = 241
5·y = 241 - 9·x
y = 241/5 - 9/5·x
Equating both equations, gives;
391/8 - 15/8·x = 241/5 - 9/5·x
391/8 - 241/5 = 15/8·x - 9/5·x = 0.075·x
0.675 = 0.075·x
x = 0.675/0.075 = 9
x = 9
Therefore, the cost of each bushes = x = $9.00
From, y = 241/5 - 9/5·x, we have;
y = 241/5 - 9/5×9 = 32
y = 32
Therefore, the cost of each bonsai trees = y = $32.00
Solve for x.
(5x - 24)
(8x + 9)
Answer:
We get two values x = 24\5
x = -9\8
Step-by-step explanation:
We can also do it by another method.
(5x - 24)
(8x + 9)
Just change the signs of 8x and 9 in minus.
we get
-3x = -33
3x =33
x = 33\3
x = 11

Greg is making accessories for the soccer team. He uses 813.44 inches of fabric on headbands for 37 players and 4 coaches. He also uses 358.16 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Total number of people including players and coach is, T = 37 + 4 = 41.
Total fabric used for making headbands is, h = 813.44 inches.
So, amount of fabric used for each person is :
[tex]F_h = \dfrac{813.44}{41}\\\\F_h = 19.84\ inches[/tex]
Total fabric used for making wristband is : w = 358.16 inches.
Amount of fabric used for each person is :
[tex]F_w = \dfrac{358.16}{41}\\\\F_w = 8.74 \ inches[/tex]
Hence, this is the required solution.

Answer:
OK aaaaaaaa. What is it
If a student is not an undergraduate business student, what is the probability they are an undergraduate student in other fields of study = 0.08
What is Probability?It deals with the occurrence of a random event.
Given that a company offers courses to prepare students for the Graduate Management Admission Test (GMAT) has the following information about its customers: 20% are currently undergraduate students in business; 15% are undergraduate students in other fields of study; 60% are college graduates who are currently employed; and 5% are college graduates who are unemployed.
P(undergraduate in business) = 0.20
P(undergraduate in other subjects) = 0.15
P(employed graduates) = 0.60
P(unemployed graduates) = 0.05
We know, P(A') = 1 - P(A)
Therefore, P(not undergraduate business) = 1 - P(undergraduate business) = 1 - 0.20 = 0.80
Hence, probability they are an undergraduate student in other fields of study = 0.08
