Step-by-step explanation:
Answer: The speed of the veneno is 220 miles per hour.
Step-by-step explanation:
We have the relation:
distance = speed*time.
We can model this situation as:
The cars will pass eachother when the sum of their distances traveled in the given time, 4 hours, is equal to the initial separation between them, 1040 miles.
So we have:
Sv = speed of the veneno.
Sp = speed of the pinto.
Sv*4hours + Sp*4hours = 1040 miles.
Now, we know that:
Sv = Sp + 180mph.
We want to find the speed of the veneno, so we should write:
Sp = Sv - 180mph.
Then we can replace this in our equation as:
Sv*4h + Sp*4h = 1040mi
(Sv + Sp)4h = 1040mi
(Sv + (Sv - 180mph))*4h = 1040 mi
(2*Sv - 180mph)*4h = 1040mi
2*Sv*4h - 720mi = 1040mi
Sv*8h = 1040mi - 720mi = 1760mi
Sv = 1760mi/8h = 220 mi/h
The speed of the veneno is 220 miles per hour.
Answer:
if asked to find stem leaf 245 scale key then 2 | 45 is what we could show to one side of the diagram.
We then use organise all numbers in numerical order lowest to highest in a horizontal list to copy.
Then draw a vertical line for your stem hopefully it is on lined paper.
single digits 1-9 go right side.
tenths get split keeping digits rights side
hundred units get split keeping tenth and single digits right side
and so forth so that nly the first number of larger numbers is on the left, just first digit. Being the first digit of numbers higher than 9.
Larger numbers that have 3 digits are more than double digits I've called 100th units
Numbers lower than 9 will be on rights side on the first line.
1-9 = 0 | 1 2 3 4 5 6 7 8 9
10-19 1 | 0 1 2 3 4 5 6 7 8 9
20-29 2| 0 1 2 3 4 5 6 7 8 9
100-110 = 1 | 00 01 02 03 etc.. becomes our first 100th line
We use thsi by counting how many numbers we have before drawing and by writing the scale key ie) 1|1 if 11 is shown etc. sometimes just called key.
Step-by-step explanation:
Answer:
108 books.
Step-by-step explanation:
Let the number of magazines = m
Let the number of books = b
<u>Given the following data;</u>
Total number of m & b = 162
<em>Translating the word problem into an algebraic equation, we have;</em>
......equation 1
......equation 2
<em>Substituting equation "1" into equation "2" we have;</em>
m = 54
Now to find the number of books;
Substituting the value of "m" into the equation, we have;
<em>b = 108</em>
<em>Therefore, the total number of books in the library is 108 books. </em>
Y = -2x + 8
The slope of the perpendicular line will be: y = -1/2x + 5
