A bicyclist going 35 mph can make it from 1st Street to the Boston Eatery in 45 minutes. How long (in minutes and seconds) will it take a motorcyclist going 40 mph?
Answer:
39.375 minutes
formula's:
distance = speed * time taken
time taken = distance/speed
speed = distance/time taken
here given:
speed: 35 mphtime = 45 minutes = 0.75 hourssolve for distance:
distance = 35 * 0.75distance = 26.25 miles1st Street to the Boston Eatery distance is 26.25 miles, which is constant.
If speed changes to 40 mph.
time taken = distance/speedtime taken = 26.25/40time taken= 0.65625 hours = 39.375 minutesFind the exponential function that contains the points (2,10) and (3,5)

Susan works part-time in a local video store. Her salary varies directly as the number of hours
worked. Last week she earned $144 for working 16 hours. This week she earned $378. How
many hours did she work this week?
Answer:
42 hours
Step-by-step explanation:
First divide 144 by 16 to get the money per hour wich is 9 then divide 378 by nine and you get the awnser, 42 hours.
Thank you
42 hours Susan worked this week to $378.
Given that, Susan's salary varies directly as the number of hours worked.
We need to find out how many hours did she work this week.
What is the direct variation?Direct variation is a type of proportionality wherein one quantity directly varies with respect to a change in another quantity. This implies that if there is an increase in one quantity then the other quantity will experience a proportionate increase. Similarly, if one quantity decreases then the other quantity also decreases. Direct variation is a linear relationship hence, the graph will be a straight line.
According to the question, last week she earned $144 for working 16 hours. This week she earned $378.
Let the number of hours she works this week be x.
So, the proportion is 144:16::378:x
⇒144×x=16×378
⇒x=42
Hence, 42 hours Susan worked this week to $378.

Your teacher asks the class to evaluate the expression (3³)¹. Your classmate gives an incorrect answer of 81. Evaluate the expression. Then find the likely error.
The most likely error is that, the student multiplied 27 by 3, after the first computation
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to determine the error in the calculation?The expression is given as
(3^3)^1
As a general rule, we start by evaluating the expression in the inner bracket
So, we have
(3^3)^1 = (3 x 3 x 3)^1
Evaluate the products
So, we have
(3^3)^1 = (27)^1
Next, we evaluate the exponent
So, we have
(3^3)^1 = 27
The above implies that the value of the expression is 27 and not 81 as the student solved
The most likely error is that, the student multiplied 27 by 3, after the first computation
Hence, the value of the expression is 27 and not 81 and the most likely error is that, the student multiplied 27 by 3, after the first computation

The first website charges a one-time membership fee of $5 and $0.99 per song.
The second website has a one-time membership fee of $10. In addition, the second website charges $0.89 per song.
Which equation could be used to determine how many downloaded songs, d, must be purchased for the cost at the two websites to be the same?
A. 5d + 0.99 = 10d + 0.89
A. , 5d + 0.99 = 10d + 0.89

A graduate student is performing a study on a new anti-anxiety drug. The drug is supposed to reduce anxiety, but the graduate student realizes that it may do nothing or even increase anxiety, so he decides to formulate non directional hypotheses and conduct a two-tailed test. He knows that the average score for all anxious people is μ₀ = 100, with a standard deviation of σ = 14. If he designates the mean for the population of anxious people who take the anti-anxiety drug as μ anti-anxiety drug anti-anxiety drug , he can identify the null and alternative hypotheses as:

Two lines are represented by the equations -1/2y=6x+10 and y=mx for which value of m will the lines be parallel
Answer:
-12
Step-by-step explanation:
So to start we need to know what makes a line parallel. In an equation we know that for lines to be parallel they must have the same slope(m).
Then, we need to know the slope-intercept form of an equation. The slope intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope of the line and [tex]b[/tex] is the y-intercept. In this problem where can see the second equation is already in this form.
Now that we know we need to find the slope, and we know that the second equation is in slope-intercept form we're going to convert the fist equation into the correct form.
To do this, we know we need to make sure [tex]y[/tex] is the only thing on the left side of the equal sign. Currently, on the left side of the equal sign we have [tex]-\frac{1}{2} y[/tex] so we have to divide both sides by [tex]-\frac{1}{2}[/tex] to get [tex]y=-12x -20[/tex]
Now that we have it converted to slope-intercept form, we are going to look for what represents the slope or [tex]m[/tex] in the equation. In this case the slope would be -12, so any line with a slope of -12 will be parallel.
