To find the average add all the numbers first.
68 + 78 = 146
56 + 74 = 130 = 276
------------------------------------------------
Now divide 276 by the number of numbers there are (4)
276 ÷ 4 = 69
------------------------------------------------------------
69 is your average

What is the volume of a cylinder with a height of 3 feet and a radius of 4 feet use 3.14 for pi
Vlad1618 [11]

Answer:

\large\boxed{V\approx150.72\ ft^3}

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

r - radius

H - height

We have the height H = 3ft and the radius r = 4ft. Substitute:

V=\pi(4^2)(3)=\pi(16)(3)=48\pi\ ft^3

\pi\approx3.14

V\approx48(3.14)=150.72\ ft^3

Jeremy used a total of 16 sticks to support his vegetables. The sticks were 55cm and 75cm long and the sum of their lengths was
svetoff [14.1K]
9 longer sticks were used.
This is how i get it.
1. change m to cm, 1m =100cm
2. add both together, divide by 16 =8.125. Which means 1 of the stick should more than 8, and 1 of the other stick should be less than 8
3. substitute the equation
4.(55 x 7)+(75 x 9) =1060

100 PTS!! PLEASE HELP! OVER DUE
Reika [66]

Answer:

-\frac{1}{2} \vec {c}

Step-by-step explanation:

Look at the component form of each vector.

Note that vector c is <4,4> and vector d is <-2,-2>

If one imagined the line that contained each vector, the line for both would have a slope of 1, because \frac{4}{4}=1=\frac{-2}{-2}

Since they have the same slope they are parallel, but since they are in opposite directions, we often call them "anti-parallel" (simply meaning parallel, but in opposite directions).

If two vectors are parallel, one vector can be multiplied by a scalar to result in the other vector.  This means that there is some number "k", such that k \vec{c} = \vec {d}, or equivalently, kc_x=d_x and kc_y=d_y.

If kc_x=d_x and kc_y=d_y, we just need to substitute known values and solve for k:

kc_x=d_x\\k(4)=(-2)\\k=\dfrac{-2}{4}\\k=-\frac{1}{2}

Double checking that k works for the y-coordinates as well:

kc_y=d_y

(-\frac{1}{2}) (4)    ?    (-2)

-2=-2 \text{ } \checkmark

So, -\frac{1}{2} \vec {c} = \vec {d}
