Answer:

Technical units conversion tool for speed and velocity measures. Exchange reading in feet per minute unit ft/min into miles per hour unit mph as in an equivalent measurement result (two different units but the same identical physical total value, which is also equal to their proportional parts when divided or multiplied).

One foot per minute converted into mile per hour equals = 0.011 mph

1 ft/min = 0.011 mph

Step-by-step explanation:

Answer:

 A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

         A2 - AB + BA - B2 =

         A2 - AB + AB - B2 =

         A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  4  is the square of  2 

Check :  a2  is the square of  a1 

Check :  b2  is the square of  b1 

Factorization is :   (2a + b)  •  (2a - b) 

Answer:

750

Step-by-step explanation:

Pick one of the schools as the host. There are C(5, 2) ways to select the two representatives from that school and C(5, 1) ways to pick a representative from each of the other schools. So once we have selected a host school, there are 10*5*5=250 ways to pick the representatives. However, any of the three schools can be the host, so we need to multiply 250 by 3 to get 750 ways.

3.14

Step-by-step explanation:

all of them problem is 3.14

The solution of the every given ratio is 3.14.

The number π is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159.

Given that, are the circle's circumferences and their diameters,

we need to find the ratio of both,

Since, we see that, the pi is the  ratio of a circle's circumference to its diameter, approximately equal to 3.14159.

So, when we will solve the ratios given we will get pi,

Because the ratios are of circumferences and diameters,

So, the value of each ratio is 3.14

Hence, the solution of the every given ratio is 3.14.

Answer:

Here I will explain this for you

Step-by-step explanation:

For the first questions 21-28 all you have to do is plug in 11 for s and plug in 8 for v. So then you would solve for the answers and that's all. For 29-34 a little hint is for you todo everything that is in () first than [] then multiply that answer by the outside number. For 35 and 36 plug in what you know form what it tells you into the formula. B=4 and H=9 for example plug that into the formula that they give which is bh/3 and you would get your answer. But always try to do the square root first if they give you that in the number. Also, don't forget to label your answer (cm) for the last to questions.
