Answer:

7

Step-by-step explanation:

We do not know the number, so we will let a variable take its place. I will be using n to represent this unknown number.

n=mystery number

Now that we have a variable, we can perform operations on it. Five less than four times a number is multiplying the number by 4 and then subtracting it by 5.

4n-5

Assuming that the second part is equal to the first part, nine more than twice a number is multiplying the number by 2 and then adding 9. We can set this equal to our previous expression.

4n-5=2n+9

2n-5=9

2n=14

n=7

Solving this equation is all we have to do to find the answer.

A 6 foot tall football player casts a 16 inch shadow at the same time stadium we discussed at six for shadow how tall the bleach
katrin [286]
You need to use a ratio of height (H) to shadow length (L) to solve the first problem. It's basically a use of similar triangles, with two perpendicular sides, and with the shadow making the same angle with the vertical.

6 ft = 72 ins, so that rH/L = 72/16 = 9/2 for the player.

So the bleachers are 9/2 x 6 ft = 27 ft.

For the second problem, 9 ft = 108 in, so that the ratio of the actual linear dimensions to the plan's linear dimensions are 9ft/(1/2in) = 2 x 108 = 216.

So the stage will have dimensions 216 times larger than 1.75" by 3".

That would be 31ft 6ins x 54ft.

Live long and prosper.

What is a formula for the nth term of the given sequence?<br> 20,50, 125...
loris [4]

Answer:

a(n) = 20*2.5^(n - 1)

Step-by-step explanation:

Note that 50 is 2.5 times 20, and that 125 is 2.5 times 50.  Thus the common factor is 2.5.  The formula for the nth term is

a(n) = a(1)*r^(n - 1)  => a(n) = 20*2.5^(n - 1)
