NEED HELP! What is the first step to solve the equation a=2d/t^2 , where a is acceleration, d is the distance, and t is time. If

kondor19780726 [428]

Plug in a = 2 m/s^2 and d = 10 m, and solve for t (in s):

$a=\dfrac{2d}{t^2}\iff2\dfrac{\rm m}{\mathrm s^2}=\dfrac{2\cdot10\,\mathrm m}{t^2}$

$\implies t^2=\dfrac{20\,\rm m}{2\frac{\rm m}{\mathrm s^2}}=10\,\mathrm s^2$

$\implies t=\sqrt{10}\,\mathrm s$

So the answer is C.

There are approximately 7.5×10^18 grains of sand on earth. There are approximately 7×10^27 atoms in a average human body. Are th

grandymaker [24]

There are more atoms in average human body than grains of sand on Earth. We can know it because we can see that atoms' number (7 * 10^27) is being multiplied by much greater number (with 9 zeros more) than grain's number (7.5 * 10^18).

What is the volume of the cone?

Radda [10]

Data:
r (radius) = 6 cm
h (height) = 12 cm
V (volume)= ?

Formula:
$V = \frac{ \pi * r^2 * h}{3}$

Solving:
$V = \frac{ \pi * r^2 * h}{3}$
$V = \frac{ \pi * 6^2 * 12}{3}$
$V = \frac{ \pi *36*12}{3}$
$V = \frac{432 \pi }{3}$
$\boxed{\boxed{V = 144 \pi cm^3}}\end{array}}\qquad\quad\checkmark$

Answer:
D 144 pi cm^3

Can you help me solve systems of equations by elimination step by step -5x+9y=-12 3x+2y=22

Sergio039 [100]

Answer:

Step-by-step explanation:

First solve -5x+9y=-12 for x:

-5x+9y=-12

-5x+9y-9y=-12-9y

-5x=-12-9

-5x=-9-12

-5x/-5=-9/5-12/-5

x=9/5y+12/6

Substitute x into an equation

3(-9/5y+12/6)+2y=22

37/5y+36/5=22

37/5y+36/5-36/5=22-36/5

37/5y=74/5

37/5y/37/5=74/5/37/5

y=2

Substitute y in x=-9/5y+12/6

9/5(2)+12/6

x=6

Solution Set: (6,2)
