</span>Finnegan needs to get the average of 70 in 4
tests in science to be able to make it to honour roll.
Find the lowest score he received on the fourth test if his first tests are 65,
60 and 92.
let x be the missing number
=> 65 + 60 + 92 + x / 4 = 70
=> 217 + x / 4 = 70
=> 217 + x = 4 x 70
=> 217 + x = 280
=> x = 280 – 217
=> x = 63
Thus the lowest score he get is 63.</span>
Answer:
If you're rounding to the nearest two decimal places it's 12.65
Step-by-step explanation:
Pythagorean Theorem :)
12^2 + 4^2 = b^2
144+16= 160
The square root of 160 is about 12.65
Answer:
y+4 = 3(x -1)
Step-by-step explanation:
You are given two points, so you only need to find the slope. The slope is given by the formula ...
m = (y2 -y1)/(x2 -x1)
m = (2 -(-4))/(3 -1) = 6/2 = 3
The point-slope equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
Using the first point, the equation is ...
y+4 = 3(x -1)
Answer:
I would need the radius of the cone to answer this completely, bit I can get you super close and explain it.
Step-by-step explanation:
The formula for a cone is
From there, I started plugging in numbers. I set this equation equal to 540pi because both if them are the volume, so they are equal and I simplified as much as I could from there. First off, the pi cancel each other out since they're on both sides of the equation. From there you have this equation:
Then, I multiplied both sides by 3 to get rid of the fraction on the left side of the equation:
Finally, I got rid of the "squared" by putting a square root over both sides if the equation, getting this:
If I knew the radius. I could get the answer by dividing both sides by the radius.
Good luck!
