I got 14 and 12 but there are other answers as well.
How I got that: I worked backwards. I looked at what two values I could multiply to get 4x^2 and because 4x^2 is a perfect square I just went with the square root (2x). Then I looked at what two pairs I could multiply to get 12 and I went with 3x4 and 6x2. I then plopped those numbers into binomials [(2x+3)(2x+4) and (2x+2)(2x+6)] and simplified (multiplied them) to get the middle value. (I hope this helps)

What is the volume of the cylinder? Round to the nearest 10th.

nata0808 [166]

Answer:169.7

Step-by-step explanation:

To find the volume of a cylinder you can use the math formula πr^2H where r is the radius and H is the height. If you plug in the values you get π3^2(6) simplify 3^2 to get (9π)(6), you can multiply 9 by 6 to get 54 then multiply that by 3.1415 to get 169.65 which rounds to 169.7

Can someone please answer this question please answer it correctly please show work

Answer:

34) A

35) C

36) D

Step-by-step explanation:

34) The perimeter of a triangle is equal to the sum of the lengths of its sides

Sides: (6.2p + 4.5q) + (3.4p - 0.7r) + (2.9r - 4.1q)

Combine like terms (same variables)

(6.2p + 3.4p) + (4.5q - 4.1q) + (2.9r - 0.7r)

9.6p + 0.4q + 2.2r

35)

Time possibilities

1 hour - $3 - $5 = $-2 No

2 hours - $6 - $5 = $1 Yes

3 hours - $9 - $5 = $4 Yes

4 hours - $12 - $5 = $7 Yes

5 hours - $15 - $5 = $10 Yes

6 hours - $18 - $5 = $13 Yes

7 hours - $21 - $5 = $16 Yes

8 hours - $24 - $5 = $19 No

9 hours - $27 - $5 = $22 No

The possible hours that Ms. Barnes can park are 2 - 7 hours

The only inequality graph that represents all of these values is C

36)

Convert to improper fractions

Divide by finding the reciprocal

Convert back to a mixed number

$-1\frac{7}{9}$

Hope this helps :)

S=L (1 - r), for r

maria [59]

OK. Then let's solve for ' r '. That means you have to come up with an equation that says   r = everything else.

Step #1:
Write the equation you're given:   <span>S = L (1 - r)

Let's divide each side by ' L ': S/L = 1 - r

Subtract 1 from each side :    S/L - 1 = -r

Multiply each side by -1 : <em> 1 - S/L = r</em>

and there you have it.

Speed boat departed 1.75 hrs after steam boat1.8 hrs after speed boat departure, steam boat has sailed for a total: 1.8+1.75 = 3.55 hrssteam boat's speed is 36.8 km/hr, so it has traveled: 3.55*36.8 = 130.64 km
speed boat is 86.9 km behind steam boat. so it is 130.64-86.9 = 43.74 km from portspeed boat's speed = 43.74/1.8 = 24.3 km/hr
