Answer:

Answer:

150 in

Step-by-step explanation:

there are 12 in in a foot. There are 12 feet so 12*12=144. Then you add 6 because half a foot is 6 in which will give you 150 in

A sphere has a radius of 6 meters. A second sphere has a radius of 3 meters. What is the difference of the volumes of the spheres?

Answers

Answer:

791. 28 m^3\n

Step-by-step explanation:

Volume of sphere with 6 meter radius

= (4)/(3) \pi r^3\n= (4)/(3) (3.14) ( 6^3)\n= 904.32 m^3\n

Volume of sphere with 3 meter radius

= (4)/(3) \pi r^3\n= (4)/(3) (3.14) ( 3^3)\n= 113.04 m^3\n

Difference between the volume of two sphere

= (904 .32 m^3)- ( 113.04 m^3)\n= 791.28 m^3\n

∆volume = 4/3 *pi * (R^3 -r^3 )
= 4/3 *pi*((6)^3 -(3)^3)
= 252*pi
= 791.68 m^3

ASAP! Plz!!!!The equations x -2 y = 1, 3 x - y = -1, x + 2 y = -1, and 3 x + y = 1 are shown on the graph below.



⊕image below!



Which system of equations has a solution of approximately (0.6, –0.8)?
x + 2 y = - 1 and 3 x + y = 1
x - 2 y = 1 and 3 x + y = 1
x -2 y = 1 and 3 x -y = -1
x + 2 y = - 1 and 3 x-y = -1

Answers

Answer:

x + 2 y = - 1 and 3 x + y = 1

Step-by-step explanation:

See the graph attached.

From this graph, it is clear that the green line and the Purple line intersect each other at an approximate point (0.6, -0.8).

Now, the green line passes through the x-intercept (-1,0) and y-intercept (0,-0.5).

Therefore, the equation of the green line will be (x)/(- 1) + (y)/(- 0.5) = 1

x + 2y = - 1

Therefore, the first combination or the fourth combination will be the answer.

Again, the purple line passes through the point (0,1) and has a negative slope.

So, the equation of purple line will be 3x + y = 1 {Since it has negative slope}

Therefore, the first combination will be the answer.

Answer:

x + 2 y = - 1 and 3 x + y = 1

How can you find a unit rate when given a rate?

Answers

A unit rate has a denominator of 1, and rate does not. For example, I ran 18 miles in 3 hours. That is a rate of 18 miles/3 hours (18 over 3). To make that a unit rate we have to make the denominator 1, so we divide the top and bottom by 3. The unit rate would be 6 miles/1 hour (6/1).

Terrell's plant grew 2 5/8 inches in one month, and it is 7 1/4 inches tall. Write and solve an equation to find the height of the plant at the start of the month. Show that your answer is reasonable. Thanks

Answers

Answer:

4(5)/(8) inches

Step-by-step explanation:

Let initial length of the plant was "x" inches.

Plant grew 2(5)/(8) inches or (21)/(8) inches per month.

So after one month height of the plant = (x+21)/(8) inches

Height of the plant after one month = 7(1)/(4) or (29)/(4) inches

So expression will be

(x+21)/(8) =  (29)/(4)

We further solve it    x =  (29)/(4) -  (21)/(8)

                                    =  (58-21)/(8)

                                   =  (37)/(8)

                           or x  =  4(5)/(8) inches

therefore, initial of the plant was 4(5)/(8) inches height.

Here you go, hope it's right. The top one is the equation and the bottom one is the work to get the answer.
