Answer:
2 4/7 seconds
Step-by-step explanation:
Velocity and (constant) acceleration are related by ...
v = at
Filling in the numbers, we can solve for t:
18 m/s = (7 m/s²)·t
t = (18 m/s)/(7 m/s²) = (18/7) s = 2 4/7 s
It takes the cyclist 2 4/7 seconds (about 2.57 seconds) to reach 18 m/s.

Problems involving position and its derivatives can reasonably be posted in the Math section. When energy or mass get involved, the Physics section is a better place. The relevant formulas for those are not always covered in algebra classes.

-2/3 divided by (-1/2)
Answer:
4/3
Step-by-step explanation:
multiply by the reciprocal
[tex]-\frac{2}{3}[/tex] × [tex]-\frac{2}{1}[/tex] = [tex]\frac{4}{3}[/tex]
Answer: +4/3
Explanation: It's important to understand that dividing by a fraction
means the same thing as multiplying by the reciprocal of that fraction.
In other words, we can simply change the division symbol
to multiplication and flip the second fraction.
So we can rewrite this problem as -2/3 · -2/1.
We can't cross-cancel anything.
Before multiplying, take note of your signs.
A negative times a negative is a positive,
so we know that our answer will be positive.
Multiplying across the numerators and denominators, we have +4/3.

During two games, the number of points scored by a basketball team increased from 75 to 87. By what percentage did the number of points scored increase?
A - 12%
B - 14%
C - 86%
D - 16%
Answer:
D 16% increase
Step-by-step explanation:
This is ez
just did this stuff in pre algebra
The solution is Option D.
The percentage of increase in number of points is 16 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The number of points scored by the basketball team = 75
The increased points scored by the basketball team = 87
The increase in points =
increased points scored by the basketball team - number of points scored by the basketball team
The increase in points = 87 - 75
= 12 points
So , the percentage increase in points = ( increase in points / number of points scored by the basketball team ) x 100
The percentage increase in points = ( 12 / 75 ) x 100
= 0.16 x 100
= 16 %
Therefore , the percentage increase is 16 %
Hence , the percentage of increase in number of points is 16 %

A. $101.25
B. $2,601.25
C. $3,715.00
D. $10,125.00
Answer:
$292.78
Step-by-step explanation:
Add the annual interest to the loan. Then divide the total by 9 to get the monthly cost.
Answer:
its c
Step-by-step explanation:
its c because you add 2,500 + 5.4% = 2,635 than it adds 135 to 2,500.
You multiply 135 x 9 = 1215 than you add that than that = 3715.

i need help on this one aswell if anyone wants to help me.
The equation that represents the linear relationship in slope-intercept form is: y = -4.75x + 211.25
To find the equation of the linear relationship in slope-intercept form, we need to determine the slope (m) and the y-intercept (b).
First, let's calculate the slope (m) using the formula:
m = (change in y) / (change in x)
For the given data points:
(x1, y1) = (25, 92.5)
(x2, y2) = (35, 45)
m = (45 - 92.5) / (35 - 25) = -47.5 / 10 = -4.75
Now, let's find the y-intercept (b) using the formula:
b = y - mx
Using the point (x1, y1):
[tex]b = 92.5 - (-4.75 \times 25) = 92.5 + 118.75 = 211.25[/tex]
This means that for each unit increase in x, the y-value decreases by 4.75 units. The y-intercept of 211.25 indicates that when x is 0, the corresponding y-value is 211.25.
