Answer:

2 m

Step-by-step explanation:

This is because no matter what m is, the cost of one ticket is $2. So, in order to figure out what the cost of all the tickets are, you must multiply to get your answer. Therefore, your expression or equation is 2 m.

Is the power produced directly proportional to the wind speed, give reasons for your answer?

yuradex [85]

Answer:

Is the power produced directly proportional to the wind speed.

No.

A proportional function can be described as y = a * x

So (0, 0) is on the graph, not (3, 0).

0 / 3 = 0

3800/6 = 633.33

7600/9 = 844.44

13600/12 = 1133.33

The quotient y/x should be always the same.

The radius of a circle is (7n-21) inches find circumference of the circle in terms of n.

hodyreva [135]

Answer:

(14n - 42)*pi

Step-by-step explanation:

Circumference is 2 * pi * r. Since r in this case is 7n - 21, you can multiply r by 2 and pi, giving you (14n - 42)*pi

you can speed from 0 to 25 m/s in 25 seconds and your friend can speed up from 0 to 6 m/s in 6 seconds. who is faster

aksik [14]

Answer:

Neither; see below

Step-by-step explanation:

Your acceleration: $a=\frac{\Delta v}{\Delta t}=\frac{25-0}{25}=1m/s^2$

Your friend's acceleration: $a=\frac{\Delta v}{\Delta t}=\frac{6-0}{6}=1m/s^2$

Therefore, since both you and your friend accelerate at the same rate, neither is faster.

Hello everyone can you answer this for me? What is A in the equation attached? Please and thank you.

lapo4ka [179]

Answer:

a = 6

Step-by-step explanation:

Hello!

Solve:

4(3a - 4) = 56
3a - 4 = 14 (factoring out 4)
3a = 18 (adding 4 to both sides)
a = 6 (dividing by 3)

Another way:

4(3a - 4) = 56
12a - 16 = 56 (distributive property)
12a = 72 (moving like terms)
a = 6 (dividing by 12)

Distributive Property of Multiplication:

The process of distributing the outside factor to the terms in the parenthesis.

Example:

$4(3a - 4)\\\\4(3a) - 4(4)\\\\12a - 16$
