what lines are perpendicular to 2x-7y=-25
Answer:
Step-by-step explanation:
Given the line 2x-7y = -25
First let us get the slope of the line:
Rewrite the equation in the form y = mx+c
2x-7y = -25
-7y = -2x-25
y = -2x/-7-25/-7
y = 2/7 x +25/7
The slope of the line is 2/7
Ffor two lines to be perpendicular, the product of their slope must be -1
mM = -1
m(2/7)= -1
2m = -7
m = -7/2
Hence the lines perpendicular to the given line must be a line that has a slope of -7/2. Since we are not given option, we can say example of such line is y = -7/2 x + 15
A designer is trying to build the ideal sized fish tank for a customer. It must hold exactly 24 cubic feet of water and can only be 4 feet in height. If the designer increases the width of the fish tank, what must happen to the length of it so that the volume remains the same? A. The length must stay the same. B. The length must decrease. C. The length must increase.
Answer:
B. The length must decrease
Step-by-step explanation:
Given;
maximum volume of the tank, V = 24 ft³
maximum height of the tank, h = 4 ft
let the width of the tank = w
let the length of the tank = L
Volume of the tank is given by;
V = Lwh
L = V / (hw)
L = 24 / (4w)
L = 6/w
L is inversely proportional to w; an increase in w (width) will cause a decrease in L (length)
Therefore, If the designer increases the width of the fish tank, "The length must decrease"

where is ( -3 1/2, -1 1/4 ) on the coordinate plane?
Answer: ( -3 1/2, -1 1/4 ) that's where it is on the coordinate plane...
Step-by-step explanation:
The point ( -3 1/2, -1 1/4 ) on the coordinate plane is shown in the figure
How can we perceive cartesian coordinate plane?The cartesian coordinate plane is an infinite 2 dimensional plane. Any 2 dimensional figure can be drawn on an infinite 2d plane. Each of the point of a cartesian plane is tracked by a location.
It is the perpendicular distance of that point from the horizontal axis and vertical axis, usually named x-axis and y-axis. The location is then written as: (a,b), where 'a' is that point's shortest distance from the y-axis and called x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis, and called y-coordinate of that point.

alexandria earned a 64 on her test. she studied and went to her teachers remediation and earned a 92 on her retake. what was her percent of change on her tests? round to the nearest whole number
Answer:
28%
Step-by-step explanation:
92-64=28
The percentage change in Alexandria's marks would be; 44%
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100. Percentage is the ratio of the number for which you want to find percentage to the total number with which you want to compare or out of and multiply this ratio with 100.
The percentage of change = (change in amount / original amount ) x 100
Alexandria's marks in first attempt = 64
Alexandria's marks in retake = 92
Then the Change in marks = 92-64 = 28
Thus Percentage of change on her tests
= ( change in marks / initial marks) ×100
=( 28/64)×100
= 43.75 %
≈ 44 %
Therefore, the percentage change in Alexandria's marks would be; 44%

To rent a certain meeting room, a college charges a reservation fee of $18 and an additional fee of $6 per hour. The chemistry club wants to spend less than $48 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room? Use t for the number of hours. Write your answer as an inequality solved for .
Answer: t = 1 hour, 2 hours, 3 hours or 4 hours
Step-by-step explanation:
Reservation fee = $18
Additional fee per hour = $6 per hour
Number of hours to spend = t
The information in the question can be expressed as:
$18 + $6t < $48
$6t < $48 - $18
$6t < $30
t < $30/$6
t < 5
Since the number of hours will be less than 5 hours, the possible numbers of hours the chemistry club could rent the meeting room will be:
1 hour, 2 hours, 3 hours or 4 hours

A particle moves along the x-axis so that at any time t≥0 its position is given by x(t)=12(a−t)2, where a is a positive constant. For what values of t is the particle moving to the right?
Answer:
For the particle to move to the right, 0 ≤ t ≤ a
Step-by-step explanation:
The particle under motion on the x-axis given by the equation x(t) = 12(a−t)² for t ≥ 0, where a is a positive constant.
To find the values of t for which the particle is moving to the right, this implies that the particle must move along the positive x-axis. This implies that x(t) ≥ 0.
So, to find the value of t for which the particle moves to the right, we solve the inequality x(t) ≥ 0 ⇒ 12(a−t)² ≥ 0
12(a−t)² ≥ 0
(a−t)² ≥ 0
taking square root of both sides, we have
√(a−t)² ≥ √0
(a−t) ≥ 0
a ≥ t ⇒ t ≤ a
So, for the particle to move to the right, 0 ≤ t ≤ a.
Using derivatives, it is found that the particle is moving to the right for [tex]t > a[/tex], that is, values of t in the interval [tex](a, \infty)[/tex].
A particle is moving to the right if it's velocity is positive.
The position of the particle is given by:
[tex]x(t) = 12(a - t)^2[/tex]
The velocity is the derivative of the position, hence:
[tex]v(t) = -24(a - t)[/tex]
If will be positive if:
[tex]-24(a - t) > 0[/tex]
[tex]-(a - t) > 0[/tex]
[tex]-a + t > 0[/tex]
[tex]t > a[/tex]

For the equation 5y = 2 express it in form of linear equation.
(A) x + 5y = 2
(B) O-r - Sy-
Answer:
y = 2/5
Step-by-step explanation:
Here, we want to express the equation 5y = 2 in the form of a linear equation.
A linear equation is in the form y = mx + c
What this means is that we have to isolate y
Thus, we can isolate y by dividing both sides by 5
5y/5= 2/5
y = 2/5
Jamal can run 1 mile in 5.05 minutes. If Jamal maintains this pace during a 5-kilometer (5K) race, he expects to break the course record of 15.25 minutes. Is Jamal's expectation reasonable? Explain.
Answer:
The expectation is reasonable
Step-by-step explanation:
Since Jamal runs 1 mile in 5.05 minutes, and expected to run 5 km in 15.25 minutes, we need to find if this is true. So, we need to find if he can actually run 5 km in 15.25 minutes.
Now 1 mile = 1609 m and 5 km = 5000 m. So, 5 km = 5000 m × 1mile/1609 m
5 km = 5000/1609 mile
Also since Jamal runs 1 mile in 5.05 minutes, the time it takes to run 5 km = 5000/1609 mile is 5000/1609 mile × 5.05 minutes/1 mile = 25,250/1609 minutes = 15.69 minutes.
Since our calculation shows that Jamal runs a 5 kilometer race in 15.69 minutes, the expectation that he will break the record in 15.25 minutes is reasonable. He can only break the record if he runs faster since there is a difference of 15.69 - 15.25 minutes = 0.44 minutes = 0.44 × 60 = 26.4 seconds which is quite a short time. So the expectation is reasonable.
