Answer: 6.23 light-years
Step-by-step explanation:
You need to convert your given ( 5.9 *10^13 kilometers ) to light years. You do this by multiplying 5.9 *10^13 kilometers * [tex]\frac{1 light- year}{9.46 *10^12 kilometers}[/tex] now you get rid of kilometers and are left with light-years. 5.9 *10^13 divided by 9.46 *10^12 gives 6.23 light-years.

On Call - 3.5 hours: $10
Talk Time - 1/2 hour:$1.25
a.) what is the unit rate in dollars for each company?
b.) Which company offers the best deal?
c.) Another company offers a rate of $0.05 per minute. How would you find the unit rate per hour?
Answer:
a) On Call: $2.86/hour
Talk Time: $2.50/hour
b) Talk Time offers the best deal.
c) $3/hour
Multiply 0.05 by 60 because there are 60 minutes in an hour.
Step-by-step explanation:
a) On Call: 10/3.5=2.86
Talk Time: 1.25/0.5=2.50
b) On Call>Talk Time
Talk Time offers the best deal.
c) 0.05x60=3
Multiply 0.05 by 60 because there are 60 minutes in an hour.
Answer:
Step-by-step explanation:
One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).
Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.
The unit rate is 2,86:2,50
You buy a brand new wax candle that stands 6 inches tall. Knowing that the rate at which the wax melts is approximately 1/100 of an inch per minute, write a linear equation that could model this situation.
Answer:
y=-1/100x+6 or y=-1x+600
Step-by-step explanation:
6 inches is the Y intercept (600,0) if measuring by 1/100 or (6,0)
Since the wax is melting, the slope is going to be negative
y=mx+6 or y=mx+600 either is fine and would yield the same results
y=-.01x+6, y=1/100x+6 or y=-1x+600
To explainn why 6 and 600 are both fine, 6 is measuring with full inches while the 600 is measuring with .01 inches. One graph will be full numbers while the other will be decimals.
Answer:
600 minutes total
Step-by-step explanation:
Inch = 100
1/100 every minute
100/100 = 1 inch and 100 minutes
600/100 = 6 inch and 600 minutes

The value of y varies directly with x, when y = 4, and x = 9. What is the equation for the relationship?
Answer:
y = [tex]\frac{4}{9}[/tex]x
Step-by-step explanation:
Given parameters:
y = 4
x = 9
y varies directly as x ;
Mathematically ;
y ∝ x
So;
y = kx
k is the constant of proportionality;
find k;
k = [tex]\frac{y}{x}[/tex]
k = [tex]\frac{4}{9}[/tex]
So,
Equation of the relationship is;
y = [tex]\frac{4}{9}[/tex]x

Jason needs 2 ½ pounds of potatoes to feed 15 people at his Friendsgiving dinner. But, his friends just called and told him they’re each bringing more friends. How many pounds of potatoes will need to feed 50 people? Explain your reasoning.
Answer:
8 1/3, eight and one over three.
Step-by-step explanation:
First lets find the rate by dividing 15 by 2.5 You will get 6 meaning that six people eat 1 pound each. Now lets divide 6 from 6 and 1. This means that 1 person will eat 1/6 of the pounds of the potatoe. Then we can do 50 times 1/6 and we will get 8.3333. This means that Jason needs 8 and 1/3 pounds of potatoes to feed 50 people.
