Three numbers are in the ratio 2 : 3 : 4. The sum of their cubes is 33957. Find the largest number

Answers

we take each number as x = 2x 3x 4x
(2x)³+(3x)³+(4x)³=33957
8x³+27x³+64x³=33957
99x³=33957
x³=33957÷99
=∛343
x=7
2x=2×7=14
3x=3×7=21
4x=4×7=28
=the three numbers are 14,21,28

a culture started with 2000 bacteria after 6 hours it grew to 2400 bacteria how many bacteria will grow after 16 hours

Answers

First, you have to find the unit rate by dividing
2000/6=333.33 but round it up to 333
So the unit rate is 333 bacteria per hour
Then, you have to multiply
333x16= 5,328 bacteria after 16 hours

The answer is that in 16 hours, there will be 5,328 bacteria

What is the slope of (6,8) (3,12)

Answers

slope=(y2-y1)/(x2-x1) when given the oints (x1,y1) and (x2,y2) we are given (6,8) and (3,12) x1=6 y1=8 x2=3 y2=12 slope=(12-8)/(3-6)=4/-3=-4/3 slope=-4/3 aka -1 and 1/3 -4/3 is slope

Slope is 4.5. equation is m=(y1-y2)/(x1-x2)
