Answer:
She will get 12 books from the store
Step-by-step explanation:
We can use ratio's to solve
2 books out x books out
------------------- =-----------------------------
3 books in 18 books in from Val
Using cross products
2 * 18 = 3 *x
Divide each side by 3
2*18 /3 = 3x/3
2*6 = x
12 =x
She will get 12 books from the store
Answer:
100 miles
Step-by-step explanation:
Relative Speed: 60+40=100 mph
you can think that one train is stationary,another one is 100 mph
so one hour before the train pass each other，the distance is 100 miles
Answer:
V=3926.99 liters
Step-by-step explanation:
cylindrical Is half full of oil The cylinder Has a base radius of 100 cm The height of the cylinder 250cm 1 litres = 1000cm3 How many litres of oil are in the tank?
Volume of a cylinder can be calculated using below formula
V=π r^2 h
Where r= radius
h= height
radius = 100 cm
h=250cm
But the cylinder is half filled, then the formula becomes
V=(π r^2 h) × 1/2
Then substitute the values we have
V=( π × 100^2 ×250) × 1/2
V=3926990 cm^3
But 1 litres = 1000cm3
Then V=(3926990 cm^3)/ 1000
V=3926.99 liters

Step-by-step explanation:
Answer:
(0,0) is among the solutions
Step-by-step explanation:
The given inequality is 
A solution to this inequality is any ordered pair that satisfies the inequality.
Let us check for x=0 and y=0
We substitute to get:
....This is true.
Therefore (0,0) is a solution to the given inequality.
There are infinitely many solutions.
