These 2 terms cannot be simplified any further, but if you are looking to factor the expression, that would be -x(x+9)

Which number is between 1/2 and 8/9 ? 1/3 19/24 7/24 22/24

Helen [10]

Answer:

5/9, 11/18, 2/3, 13/18, 7/9, 15/18

Step-by-step explanation:

To find the number between these 2, see what is between it:

to see the number between 1/2 and 8/9, we have to:

Times 1/2 by 9 times = 1/2 * 9 = 9/18

Times 8/9 by 2 times = 8/9* 2 = 16/18

So the number between 9/18 and 16/18 would be"

10/18, 11/18, 12/18, 13/18, 14/18, 15/18

Simply some of that, we got:

5/9, 11/18, 2/3, 13/18, 7/9, 15/18

Hope this help you :3

Write the equation.Please help

Scorpion4ik [409]

Answer: y=3x

Step-by-step explanation:

We want an equation of the form y=mx+b where m is the slope and b is the y-intercept (the value of y when x is 0).

The slope: From the point (0,0), the braph goes to point (2,6). Slope is the rise (y) over the run(x): (6/2) or 3. The slope, m, is 3. b, the y-intercept, is 0. y is 0 when x is 0.

y=3x

The volume of a cylinder is 97 ft cubed. if the dimensions are doubled, what will be the new volume?

Airida [17]

See, pls, this explanation:
1) formula for volume of cylinder is: V=πR²h, where R - radius of the bottom (circle), h - height of the cylinder.
2) if new_R=2R and new_h=2h then new_V=π(new_R)²(new_h)=8πR²h=8*97=776 ft³

Answer: 776 ft³.

Is the sequence 4, 8, 12, 16, 20, ... a geometric sequence? If it is a geometric sequence, what is the common ratio?

vovangra [49]

Answer and Step-by-step explanation:

This sequence is NOT a geometric sequence.

It is an arithmetic sequence, because the numbers are going up using addition, going up each time by 4.
