Velocity?
Distance = 825m
time= 32s
v=d/t
= 825m/32s
= 25.8 m/s
Example:
A cart travels down a ramp at an average speed of 5.00 centimeters/second. What is the speed of the cart in miles/hour? <span> To solve this problem we have set the conversion values to determine the product during the conversion process. </span><span><span>
1. </span>1 centimeter = 0.00000621371 mile</span> <span><span>
2. </span> 1 hour = 60 minutes</span> <span><span>3. </span> 1 minute = 60 seconds</span>
<span>Thus, we shall have </span>
<span><span>1. </span>5 cm x 0.00000621371 mile/1cm = 0.000031069 mi</span>
<span><span>2. </span>0.000031069 seconds x 1 hr / 3600 = 0.111846815 miles / hr</span> <span> </span>
![4x^2+13=49](https://tex.z-dn.net/?f=4x%5E2%2B13%3D49)
To solve the value of x in the above equation, here are the steps.
1. Subtract 13 on both sides of the equation.
![\begin{gathered} 4x^2+13-13=49-13 \\ 4x^2=36 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%204x%5E2%2B13-13%3D49-13%20%5C%5C%204x%5E2%3D36%20%5Cend%7Bgathered%7D)
2. Divide both sides of the equation by 4.
![\begin{gathered} \frac{4x^2}{4}=\frac{36}{4} \\ x^2=9 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B4x%5E2%7D%7B4%7D%3D%5Cfrac%7B36%7D%7B4%7D%20%5C%5C%20x%5E2%3D9%20%5Cend%7Bgathered%7D)
3. Get the square root on both sides of the equation.
![\begin{gathered} \sqrt[]{x^2}=\sqrt[]{9} \\ x=\pm3 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Csqrt%5B%5D%7Bx%5E2%7D%3D%5Csqrt%5B%5D%7B9%7D%20%5C%5C%20x%3D%5Cpm3%20%5Cend%7Bgathered%7D)
The possible values of x are +3 and -3. The smaller value is -3.
Then 1 white, then 3 blue then 1 white
Answer:
The value of angle in degrees equals 210 degrees
Step-by-step explanation:
Since we know that
radians equals ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
Thus by ratio we have ![1rad=\frac{180}{\pi }degrees](https://tex.z-dn.net/?f=1rad%3D%5Cfrac%7B180%7D%7B%5Cpi%20%7Ddegrees)
thus
radians equals
![\frac{7\pi }{6}\times \frac{180}{\pi}\\\\=210^{o}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5Cpi%20%7D%7B6%7D%5Ctimes%20%5Cfrac%7B180%7D%7B%5Cpi%7D%5C%5C%5C%5C%3D210%5E%7Bo%7D)
Answer:
98 cm²
Step-by-step explanation:
Lateral surface area = surface area of the sides ONLY of the object
⇒ lateral SA = B + C + D = 35 + 28 + 35 = 98 cm²
