C(-7,-5)What factor is used to covert feet per minute into miles per minute
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:
A club has $5$ members from each of $3$ different schools, for a total of $15$ members. How many possible ways are there to arrange a presidency meeting under the following conditions: i. The club must choose one of the $3$ schools at which to host the meeting, and ii. The host school sends $2$ representatives to the meeting, and each of the other two schools sends $1$ representative.
Please answer this correctly, I will mark the person who gets it correct Brainliest.
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.

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: ......
Step-by-step explanation: ....
Please answer this I need help.
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.

Answer:
3.14
Step-by-step explanation:
all of them problem is 3.14
The solution of the every given ratio is 3.14.
What is pi?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.
