Let x and y represent the numbers of gallons used by the 40 mpg and 35 mpg cars, respectively.
.. x +y = 40 . . . . . . . . . . .total consumption is 40 gallons
.. 40x +35y = 1525 . . . . total miles driven = 1525
Multiply the first equation by 40 and subtract the second.
.. 40(x +y) -(40x +35y) = 40(40) -(1525)
.. 5y = 75
.. y = 15
.. x = 40 -15 = 25
The 40 mpg car consumed 25 gallons.
The 35 mpg car consumed 15 gallons.
35
since m and n are the midpoints of ab and ac resistively
then ,bc=2mn=16
since m and l are the midpoints of ba and bc respectively
then, ac =2mn =10
then,nc =1/2 × 10 =5
similary, mb=6
then ,perimeter=nc+mb+mn+bc=5+6+8+16=35
Answer:
this is only one functions, it means all is correct.
Short Answer: 5/36
How many ways can you throw two 6 sided dice?
Since each dice has six sides, the total number of ways is 6*6 = 36 ways.
How many ways can an 8 be thrown? To make the differences easier to see use a green colored die and a red colored die.
Red Green
2 6
6 2
5 3
3 5
4 4 That's five different ways of getting an 8.
The probability is
