Given that: Train travels 432 miles in every 4 hours

To Find: Unit rate of the train

⠀⠀⠀⠀⠀⠀<u>__________________</u>

Solution:-

we can find the unit rate of train by divide the distance and time.

⠀⠀

:\implies\sf{speed(v)} \:  =   \dfrac{distance(s)}{time(t)}

:\implies\sf Speed\; (v) = \dfrac{423}{9}

:\implies\sf Speed \: (v) = 47 \;mph\;(miles\;per\;hour)

⠀⠀⠀⠀

\therefore \underline {\sf{Hence \: , \:  \pmb{47mph} \: is \: the \: required \: answer}}

How can you solve standard form and intercept form?
laiz [17]

Answer:

The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept.

-3(1-2x)-3=-20-8x what is the work and answer
larisa86 [58]
You have to keep order of operations in mind.

1. Take care of the parentheses; distribute.
-3+6x-3=-20-8x
Simplified: 6x-6=-20-8x

2. Isolate the x variable.
Add 8x to both sides and add 6 to both sides.
14x=-14

3. Solve for x.
Divide by 14 on both sides.
x=-1

Sergeu [11.5K]

Answer:

m = 10

Step-by-step explanation:

Find 'n' first..... then pythag theorem for 'm'....

n is to 5    as  15 is to n

n/5   = 15/n

n^2 = 75     n = sqrt (75)

Then   m^2 =  n^2 + 5^2

            m^2 = 75  +  25       s-o-o-o-o:     m = 10

A sweater that normally costs $32.00 is on sale for $24.00. What is the percent
Vlad1618 [11]

Answer:

25 %

Step-by-step explanation:

Percentage is given by :

\%=\dfrac{\text{original value-new value}}{\text{origial value}}\times 100

Original cost of sweater is $32 and sale cost is $24. So,

\%=\dfrac{32-24}{32}\times 100\\\\=25\%

Hence, 25 % is the markdown on the sweater.
