Answer:
47 mph.
Step-by-step explanation:
The unit rate would be in mph.
Divide 423 miles with 9 hours:
423/9 = 47
47 mph, or miles per hour, is your answer.
~
Given that: Train travels 432 miles in every 4 hours
To Find: Unit rate of the train
⠀⠀⠀⠀⠀⠀__________________
Solution:-
we can find the unit rate of train by divide the distance and time.
⠀⠀
[tex]:\implies\sf{speed(v)} \: = \dfrac{distance(s)}{time(t)} [/tex]
[tex]:\implies\sf Speed\; (v) = \dfrac{423}{9}[/tex]
[tex]:\implies\sf Speed \: (v) = 47 \;mph\;(miles\;per\;hour)[/tex]
⠀⠀⠀⠀
[tex]\therefore \underline {\sf{Hence \: , \: \pmb{47mph} \: is \: the \: required \: answer}}[/tex]

Melissa has a total of $250 in her savigns account. She started with $110 and then earned the rest of her savings by babysitting. Melissa charges $7 per hour. Write an equation to represent the situation and determine the number of hours (h) she babysat last week.
Answer:
Number of hours= 20 hours
Step-by-step explanation:
Giving the following information:
Net savings (babysitting)= 250 - 110= $140
Rate per hour= $7
To calculate the number of hours that Melissa worked as a babysitter, we need to use the following formula:
Number of hours= net savings / rate per hour
Number of hours= 140 / 7
Number of hours= 20 hours

Answer:
A is the answer
Step-by-step explanation:
6 times 3.14 is 18.84
Given,
Diameter of circle = 6 in.
As we know that radius is half of diameter.
Radius = 6 × 1/2 = 3 inches
Now,
[tex] \sf Circumference \: of \: circle = 2 \pi \: r[/tex]
[tex] = \: 2 \times \dfrac{22}{7} \times 3[/tex]
[tex] = \dfrac{44}{7} \times 3[/tex]
[tex] = \dfrac{132}{7} [/tex]
[tex] = 18.84\: in.[/tex]
Hence,option ( a ) is correct.
When Emily arrives from school she spent a minute eating a snack then she spent 15 playing with her dog and 32 doing her chores
The question is incomplete:
When Emily arrived home from school she spent a minutes eating a snack. Then, she spent 15 minutes playing with her dog and 32 doing her chores . Finally, Emily spent 45 minutes finishing her homework. How long had Emily been home when she finished?
Answer:
Emily had been home for 1 hour and 33 minutes.
Step-by-step explanation:
In order to find the answer, first you have to add up the time she spent in each activity to find the amount of minutes she had been at home when she finished:
1+15+32+45=93
Now, you can express the 93 minutes in hours considering that one hour has 60 minutes. According to this, Emily had been home for 1 hour and 33 minutes (93-60=33).

how do you write the equation of a line in slope intercept form looking at a table?
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept
1) Determine the slope (m)
To find the slope, take two points from the table, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] and plug them into the following equation to solve for m:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Plug m into [tex]y=mx+b[/tex] .
2) Determine the y-intercept (b)
Take any point given in the table and plug them into [tex]y=mx+b[/tex] (along with the slope that you solved for earlier) as [tex](x,y)[/tex]. Solve for b. Plug b back into [tex]y=mx+b[/tex] along with the slope.

What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
It is given that Mr. Ammons is constructing a walkway through his rectangular Garden. The walkway runs diagonally as shown in the diagram.
We need to find the length of the walkway.
Using Pythagoras Theorem;
[tex]15^2 + 24^2 = x^{2} \\\\x^{2} = 225 + 576\\\\x^{2} = 801\\\\x = \sqrt{801} \\\\x = 28.30[/tex]
Therefore, 28.3 ft is closest to the length of the walkway. answer will be Option B. 28.3 ft

A line has slope = 0 and goes through the point (1, 6). What is the equation of the line in slope-intercept form?
a) y = 1
b) y = 6
c) x = 1
d) x = 6
Answer:
y = 6.
Step- by-step explanation:
A slope of 0 means that the line is horizontal and would be of the form y = k.
As is pass through the points where y = 6 ( 1, 6) :- it is y = 6.
