Answer:

3.5

Step-by-step explanation:

If AM=5, then so is MC because the angles are equal.

So AC must be 5+5 = 10.

If BD=17, you can subtract AC=10, so you keep 7 for BA + CD.

Since these angles are also equal, you can divide 7 evenly so you get:

BA = CD = 7/2 = 3.5

K=mv^2/2 solve for v

matrenka [14]

Answer: $v=\sqrt[]{\frac{2K}{m} }$

Step-by-step explanation:

$K=\frac{mv^2}{2}$

First, multiply by 2 to get rid of the 2 in the denominator. Remember that if you make any changes you have to make sure the equation keeps balanced, so do it on both sides as following;

$2*K=\frac{mv^2}{2}*2$

$2K=mv^2$

Divide by m to isolate $v^2$ .

$\frac{2K}{m}=\frac{mv^2}{m}$

$\frac{2K}{m} =v^2$

To eliminate the square and isolate v, extract the square root.

$\sqrt[]{\frac{2K}{m} }=\sqrt[]{v^2}$

$\sqrt[]{\frac{2K}{m} }=v$

let's rewrite it in a way that v is in the left side.

$v=\sqrt[]{\frac{2K}{m} }$

There are 24 students in Ms. Messing's class 6 more students walk to school then ride their bikes thus number of students who ri

Juli2301 [7.4K]

Walk = x + 6
Bike = x
Driven = x

x + x + x + 6 = 24
combine like terms

3x + 6 = 24
subtract 6 from both sides

3x = 18
divide both sides by 3 to isolate x

x = 6

Walk = x + 6 = 6 + 6 = 12

12 students walk to school.
