Answer: To show that a conjecture is false, you have to find only one example in which the conjecture is not true. So an example could be a drawing, a statement, or a number.

valina [46]

Answer:

<em>I will need to buy 22.5 pounds of turkey and pay $23.63</em>

Step-by-step explanation:

<u>Proportions</u>

Each person is planned to eat 2 x 3/8 pound servings of turkey for thanksgiving dinner. This means each person will eat

2\cdot\frac{3}{4}=\frac{3}{2}

pounds of turkey.

There are going to be 15 people at the dinner, thus the total turkey needed is:

15\cdot\frac{3}{2}=22.5~pounds

The turkey costs $1.05 per pound, thus the total cost is

22.5*$1.05 = $23.63

I will need to buy 22.5 pounds of turkey and pay $23.63

A plumber has a set fee for a house call and charges by the hour for repairs. The total cost of her services can be modeled by c
Lostsunrise [7]

Answer:

1, 2 and 3

Step-by-step explanation:

Let

t -----> the number of hours the job takes

C(t) -----> the total cost for the service

we have

C(t)=125t+95

This is the equation of a line in slope intercept form

where

The slope m is equal to m=125\ \frac{\$}{h}

The y-intercept is the point (0,95) ---> The cost is $95 for the value of t equal zero (fee)

therefore

<u><em>The statements that are true</em></u>

1 a house call fee costs $95

2 the plumber charges $125 per hour

3 the number of hours the job takes is represented by t
