Answer: Volume = 11,898.98

Find radius: 1.4*19.75=27.65/2=13.825

Find volume: πr^2h= π*13.822*19.75=11858.97771

Round to get 11,898.98

Answer:

V=11858.98

Step-by-step explanation:

V=r^2*pi*h

first find r

r=d/2

d=1.4(19.75)

d=27.65

r=27.65/2

r=13.825 ft

plug into volume equation

V=13.825^2*pi*19.75

V=11858.97771

V=11858.98 ft^3

Answer: S<\-2

Hope i was some help.

Step-by-step explanation: sorry I can’t put the right sign my keybored won’t let me but you know what it stands for.

3s+6s</-5(s+2)

start off with -5(s+2) you multiply -5 with s and it is -5s then you do the same for +2 take -5 and multiply by +2 pos times a neg is always a neg so it’s -10.

3s+6<\-5s-10

So you have to get rid of the -5s so your going to do the inverse which is add 5 to -5 and it will get rid of -5s but then you have to add 5 to 3s and that will be 8s.

8s+6</-10

Now your going to get rid of the +6 and to do that you do the inverse you subtract 6 and it will get rid of it now you have to do the same for -10 so you will subtract 6 to -10 and that will equal -16.

Now you have to divide!

8s/8 </ -16/8

And it should equal s <\-2

It is known that 5< x< 8. find all possible values of the expression, 6x, -10x,x-5,3x+2

Nuetrik [128]

Answer:

Part 1) $30< 6x< 48$

Part 2) $-80< -10x< -50$

Part 3) $0$

Part 4) $17< 3x+2< 26$

Step-by-step explanation:

we know that

$5< x< 8$

The solution for x is the interval ----> (5,8)

All real numbers greater than 5 and less than 8

Part 1) Find all possible values of the expression 6x

For x < 8

The expression value is 6x < (6)(8) -----> 6x < 48

For x > 5

The expression value is 6x > (6)(5) -----> 6x > 30

therefore

$30< 6x< 48$

Part 2) Find all possible values of the expression -10x

For x < 8

The expression value is -10x > (-10)(8) -----> -10x > -80

For x > 5

The expression value is -10x < (-10)(5) -----> -10x < -50

therefore

$-80< -10x< -50$

Part 3) Find all possible values of the expression x-5

For x < 8

The expression value is x-5 < 8-5 -----> x-5 < 3

For x > 5

The expression value is x-5 > 5-5 -----> x-5 > 0

therefore

$0$

Part 4) Find all possible values of the expression 3x+2

For x < 8

The expression value is 3x+2 < 3(8)+2 -----> 3x+2 < 26

For x > 5

The expression value is 3x+2 > 3(5)+2 -----> 3x+2 > 17

therefore

$17< 3x+2< 26$

Find the y-intercept and x-intercept of the line.<br> – 3x+9y= 14

pickupchik [31]

Answer:

$\huge\boxed{x-intercept=-\dfrac{14}{3}=-4\dfrac{2}{3}}\\\boxed{y-intercept=\dfrac{14}{9}=1\dfrac{5}{9}}$

Step-by-step explanation:

$-3x+9y=14\\\\x-intercept\ \text{for}\ y=0:\\\\-3x+9(0)=14\\-3x+0=14\\-3x=14\qquad\text{divide both sides by (-3)}\\\boxed{x=-\dfrac{14}{3}=-4\dfrac{2}{3}}}$

$y-intercept\ \text{for}\ x=0:\\\\-3(0)+9y=14\\0+9y=14\\9y=14\qquad\text{divide both sides by 9}\\\boxed{y=\dfrac{14}{9}=1\dfrac{5}{9}}$
