<u>Ratios and Proportions
</u>
The ratio between two numbers x and y is defined as x/y. It measures how many times y is contained in x. For example 12/8 = 1.5 means 12 is 1.5 times 8.
We have two key sets of data: the ratio between the surface areas of the cylinders and the fact that the radius and heights of the cylinders come in the same proportion.
First, we can easily compute the ratio of the surface areas
It gives us the relation
Computing the square root
Computing the cube
204.8 apples.
First you would find out how many ounces are in 8 pounds, which would be 128. then do 128/5 to get 25.6 < that would be how many apples are in 8 pounds. Next you would do 224/28 to find out how many of the 8 pounds you can buy for 224 dollars. so you get 8 from that. So now we do 25.6*8 to get 204.8 apples.
204 apples rounded down and 205 apples rounded up
Martín had 164 apples and wanted 56 more than he ate 8 . How many are left ?
Answer:
y = 2x-16
Step-by-step explanation:
To find a line when we know the slope and a point, we can use the point slope formula for a line
y-y1 = m(x-x1)
where the point is (x1,y1) and the slope is m. Substituting the known information in.
y--8 = 2 (x-4)
y+8 = 2(x-4)
We can manipulate this into slope intercept form by distributing the 2
y+8 = 2x-8
and subtracting 8 from each side
y+8-8 = 2x-8-8
y = 2x-16
Those odd numbers are nine and seven.
