You have a 1.5 litre bottle of water and drink 295 millilitres. Your friend drinks 135 millilitres. How much is left?
1 answer:
Convert liters to milliliters so that you have one unit for all of the amounts in the question.
1 liter is equal to 1000 milliliters, so multiply the 1.5 liters you have by 1000:
Since you drank 295 milliliters, and your friend drank 135 milliliters, you will subtract those values from the amount in the bottle:
There is 1070 milliliters of water left in the bottle.
If you want to find the amount remaining in the bottle in liters, divide the amount remaining by 1000 to convert milliliters to liters:
Converted back into liters, there is 1.07 liters of water left in the bottle.

Answer:
slope = -
Step-by-step explanation:
note that BC is perpendicular to AB, hence the slope of BC is the negative reciprocal of the slope of AB
= -
= -
Answer:
Part A: The length of each side is units long.
Part B: The dimensions are 5x-4 and 5x+4 units long.
Step-by-step explanation:
Part A:
-->
--> Multiply 9 times 4 to see the factors of that product
--> 9 times4 = 36
Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36
Use the factor 6 and make it negative so -6
add another -6
Keep in mind that it is -6x
--> 9x^2-6x-6x+4
Separate the four terms into two different binomials
--> 9x^2-6x and -6x+4
Factor the binomials
With 9x^2-6x you can factor a 3x
So it will 3x(3x-2)
Do the same thing with -6x+4
You can factor out a -2
-2(3x-2)
The reason you factor out a -2 and not 2 is because it has to be same so in this case it is (3x-2)
Take the two numbers that you factored and put them to make an expression so (3x-2)
--> (3x-2)(3x-2) or (3x-2)^2
3x-2 is the length of each side so it is 3x-2 units long
Part B:
-->25x^2-16y^2
Use the difference of squares
take the square root of 25x^2
that is 5x
take the square root of 16y^2
that is 4y
write it in this way (5x+4y)(5x-4y)
These are the dimensions of the rectangle
