Answer:
There are 25 two point questions, and 10 six point questions
Step-by-step explanation:
First note that if all the questions were value 6, this would give 6x35 = 210 points.
Each time we swap a 6 point question to a 2 point question, the totl points decrease by 4.
So as 110 is 100 less then 210, and 100÷4 =25, this means we know that if we decrease the number of 6 point questions from 35 to 10 (i.e. 35-25), this should give the answer.
So i.e. there are 10 six point questions, meaning there are 35-10 = 25 two point questions. (we can also check this does indeed give 110, as
10x6 + 25 x2 = 60 +50 = 110 )

Answer:
y=3x-9
Step-by-step explanation:
Hi there!
we are given a point (4,3), and a line (y=-1/3x+4)
Perpendicular lines have slopes that are negative and reciprocal; if they are multiplied together, the result is -1
first, let's find the slope of the new line.
we can find it with this formula: (m=slope)
-1/3m=-1
multiply both sides by -3
m=3
here's our equation so far, written in y=mx+b form, where m is the slope and b is the y intercept
y=3x+b
we need to find b
Because the line passes through the point (4,3), we can use it to find b
substitute x as 4 and y as 3
3=3(4)+b
multiply
3=12+b
-9=b
substitute into the equation
<u>y=3x-9</u>
Hope this helps!

Hello from MrBillDoesMath!
Answer:
r = = 57.6 (approximately)
Discussion:
Given: circumference of circle O = 362.14
The circumference of a circle of radius r, is given by the formula C = 2 *PI *2.
So we need to find the value of r in
2*Pi*r = 362.14
Divide both sides by 2*PI to get
r = (362.14)/ (2 * Pi) = (362.14)/ 6.283 (approximately)
= 57.6 (approximately)
Thank you,
