a babysitter charges 9 dollars each hour she works plus a travel allowance of 5 dollars for each job. write an equation that relates the number of hours. the babysitter worked at a job for which she charged 77 dollars. how many hours did she work?
Answer:
y=9x +5 , 8 hours
Step-by-step explanation:
9 dollars per hour = 9x
travel allowance = 5
y = 9x + 5
77 = 9x + 5
77 = 9x +5
-5 -5
-----------------
72= 9x
72/9 = x
x= 8

Nathan is planning to ride his bike for 24 minutes. If he rides at a rate of 3 miles per hour, how far will he travel?
Answer:
1.2 miles in 24 minutes
Step-by-step explanation:
3 miles per hour = .05 miles per minute
24 x 0.05 = 1.2
Remember that speed is defined as the rate of change of the position respect to the time, thus we can define the relation:
Distance = Spee*Time.
Using this we will get the solution: distance = 1.2 miles
Let's see how to get the solution:
We start with the given information:
Nathan rides for 24 minutes.His speed is 3 miles per hour.So we got a time and we also have a speed, but the time units in these are different.
So knowing that:
1 hour = 60 minutes
(1 hour/60 minutes) = 1
Then we can write:
24 minutes = (24 minutes)*(1 hour/60 minutes) = 0.4 hours
Then we have:
time = 0.4 hours
speed = 3 miles per hour.
Then, using the first equation, we get:
distance = (3 miles per hour)*0.4 hours = 1.2 miles.

a waterslide has an angle of elevation of 20 degrees whats is the rise for a run of 2.6 m?
Answer:
Therefore, the rise will be 0.95 m
Step-by-step explanation:
As the waterslide has an angle of elevation of 20 degrees.
Ф = 20°
And we have to determine the rise for a run of 2.6 m.
All we need is to use the trigonometric ratio of tan Ф
Because
tan Ф = rise/runAs
run = 2.6 m
Ф = 20°
so
tan Ф = rise/run
tan (20) = rise/run
rise = tan (20) × 2.6
rise = 0.95 m
Therefore, the rise will be 0.95 m

Answer:
y= -1/2 + 2
Step-by-step explanation:
To find m or the slope you need to find 2 locations that the line intercepts a point on the graph. I used (0,2) and (2,1).
Then you find the difference of the x and y coordinates. (x,y)
X-coordinates: 0 and 2. 0 - 2 = -2
Y-coordinates: 2 and 1. 2 - 1 = 1
A slope fraction is the difference of y over the difference of x coordinates. It would be written as 1/-2 or -1/2. m= -1/2
To find the b value, just look at the y-intercept or where the line intercepts the y-axis. Which is at (0,2). So b=2

Which equation best describes the line in the graph?
Answer:b
Step-by-step explanation:
Give brainliest
Answer:
B
Step-by-step explanation:
The question is looking for an equation in slope-intercept form which is y=mx+b where m is the slope and b is the y-intercept. The y-intercept is +4, which all of the answers show, so you must find the slope.
The slope is the change in y over change in x, more commonly referred to as rise over run. So count how many units the graph changes vertically and horizontally, in this case, 1 up and 2 right, so the slope is equal to 1/2. If you have a graph where the line shifts up and left, or down and right, then the slope is negative. Additionally, one way to visually check your work is to remember slopes equal to less than -1 or greater than +1 will be steeper while fraction slopes will make the slope flatter; basically the closer to zero the less steep.
