The required value of constant variation would be 110.
What is the distance?Distance is defined as the product of speed and time.
Direct variation equation can be written as:
y = kx where "k" is a constant variation.
Here y represents the distance covered by the train, and x represents the time duration.
As per the given question,
Since the train covers 165 km in 1.5 hours.
Substitute the values of y = 165 and x = 1.5 in the direct variation equation and solve for k:
⇒ 165 = 1.5k
⇒ k = 165/1.5
Apply the division operation, and we get
⇒ k = 110
Therefore, the required value of constant variation would be 110.

Mrs. Barlow's math class took a test yesterday. Out of 100 students, 70% of them passed. How many of Mrs. Barlow's students passed the test?
Answer:
70
Step-by-step explanation:
70 percent of 100 is [tex]\frac{70}{100}[/tex]
so [tex]\frac{70}{100}[/tex] × 100 students
= 70 students
What is 12.5 percent of 40 A. 0.5 B. 0.32 C. 3.2 or D. 5

It cost Jayden $4.80 to send 96 text messages. How much would it cost to send 155 text messages?
Answer:
$7.75
Step-by-step explanation:
1. Take the cost - $4.80 for the 96 messages, and divide $4.80 by 96 to get the cost per message.
2. 4.80 ÷ 96 = $0.05 per message
3. Take that figure and multiply by 155 messages.
4. 155 × $0.05 per message = $7.75

Answer:
15
Step-by-step explanation:
40 of them are offense players, 5 are special teams which means that 15 are defensive
Answer: 2/3 of 60 = 40
1/12 of 60 = 5
40 + 5 = 45 obviously.
45 + 15 = 60.
Therefore the amount of defensive players would be 15.
Lila rode her bike from 9:30 am to 11:10 am this morning. She rode 1.5 miles every 10 minutes. What is the total number of miles Lila rode this morning?
Answer:
15mi
Step-by-step explanation:
9:30am to 11:10am equals 100 minutes
100 minutes divided by 10 minutes per segment equals 10 segments
1.5 miles per segment multiplied by 10 segments equals 15 total miles
A vertical parabola goes through (1,-2), (-3, 10), and (4, 31). Use matrices to
solve for D, E, and F, given the general form x² + y2 + Dc + Ey + F = 0 (since it
is a vertical parabola there is not a z term).

Answer:
D = 1/2 , E = -1/2 , F = -5/2
Step-by-step explanation:
vertical parabola : ( 1,-2), ( -3, 10 ), (4, 31 )
General form ; [tex]x^2 + y^2 + Dx + Ey + F = 0[/tex]
( 1 ,-2 ) = x1, y1
( -3, 10 ) = x2, y2
( 4, 31 ) = x3, y3
hence :
[tex]y1 = ax_{1} ^2 + bx_{1} + c[/tex]
[tex]y2 = ax_{2} ^2 + bx_{2} + c[/tex]
[tex]y3 = ax_{3} ^2 + bx_{3} + c[/tex]
attached below is the detailed solution required
D = 1/2 , E = -1/2 , F = -5/2

So, every single one except 0.
x > -3
x is greater than -3.
i.e -2, -1, 0, 1, 2, 3, 4, 5, . . . . .
From the given option we can select the correct answers.
We see that,
0, 3, and 6 are the correct answer.
The values of x that are solutions to the given inequality are 0, 3, and 6.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
7 + 4x > x - 2
Solve for x.
7 + 4x > x - 2
Subtract x on both sides.
7 + 4x - x > -2
7 + 3x > -2
Subtract 7 on both sides.
7 + 3x - 7 > -2 - 7
3x > -9
Divide both sides by 3.
x > -3
This means x is greater than -3.
i.e -2, -1, 0 , 1, 2, 3, 4, 5, . . . . .
From the given option we can select the correct answers.
We see that,
0, 3, and 6 are the correct answer.

A baker sells bread for $4 a loaf and rolls for $1 each. The baker needs to sell $36 worth of baked goods by
the end of the day.
Enter a linear equation that describes the problem.
An equation for the value of the baked goods is
bread sold, and r is the number of rolls sold.
= $36, where b is the number of loaves of
Explanation:
Cost of 1 loaf of bread = $4
Cost of 1 roll = $1
The baker needs to sell both items and it should be worth $36.
To find the linear equation, Suppose, the baker sells "b" loaves of bread and "r" rolls.
Then the total cost of the sales has to be $36.
So, the linear equation will be:
4b + 1r = 36
