You can use the pythagorean theorem
15^2 = 225
17^2 = 289
225 + b^2 = 289
b^2 = 64
b = 8
so one half of one side is 8 so the whole side would be 16
hope this helps
Answer:
First Two: 2 million,
Second Two: 2 hundred thousand
Number of biscuits shared by Mrs Perry = 25
ratio in which the biscuits were shared between Gemma and Zak = 1:4
Let us assume the common ratio = x
then
x + 4x = 15
5x = 15
x = 3
Then
The number of biscuits that Gemma got = 3
The number of biscuits that Zak got = 4x
= 4 * 3
= 12
So
Gemma: Zak = 3:12
I hope the procedure is clear enough for you to understand.
a writer will use a for the informal language
Y= -1/3x +5
5 is the y-intercept (where the line touches the y-axis) and -1/3 is the slope (rise over run, but since its negative, you go down 1, over 3 to the right) Hope this helps!!!
