Answer:

Represent the longer piece of the rope as (18 + x) and the shorter piece as x. The rope is 100 feet long, so:

(18 + x) + x = 100      Set up equation

18 + x + x = 100        Arrange like terms

18 + 2x = 100            Combine like terms

2x = 82                     Subtract 18 from both sides

x = 41                       Divide both sides by 2

Longer rope length: 12+ 31 =43 feet

Shorter rope length: 57 feet

Check: 59 + 41 = 100 feet

Answer/Step-by-step explanation:

100 divided by 2 = 50

rope a 50 divided by 10 = 5 - 2 = 3 ft

rope b 100 - 3 = 97

change 9 to 5

and change 3 to 43

a = 43

b = 57

I hope this helps you

f(g(x)) =f(x+1)=7(x+1)^2

f(x+1)=7.(x^2+2x+1)

A school baseball team earned $3416.90 from selling 5716 tickets to their game. If grandstand tickets sold for 65 cents each and
expeople1 [14]
If all were grandstand tickets, revenue would be 0.65*5716 = 3715.40. It was actually 298.50 less than that. Each bleacher ticket sold drops the revenue by .25, so there were 298.50/.25 = 1194 bleacher tickets sold.

Times for an ambulance to respond to a medical emergency in a certain town are normally distributed with a mean of 450 seconds a
Gnoma [55]

Answer:

(D)109

Step-by-step explanation:

Mean = 450 seconds

Standard deviation = 50

First, we determine the probability that the expected response time is between 400 seconds and 500 seconds, P(400<x<500)

Using the Z-Score,

P(\frac{x-\mu}{\sigma}

From the Z-Score table

P(-1<x<1) = 0.68269  

The probability that the expected response time is between 400 seconds and 500 seconds is 0.68269.

Since there are 160 Emergencies

Number whose expected time is between 400 seconds and 500 seconds

=160 X 0.68269 \approx 109
