Answer:
The ribbon cost per foot $0.6 per foot
Step-by-step explanation:
Total number of ribbon used = (5.75 + 11.75) = 17.50 feet
17.50 feet of ribbon cost = $10.50
1 foot of ribbon cost = x
Cross Multiply
17.50 × x = 1 foot × $10.50
x = 1 foot × 10.50/17.50
x = $0.6
The ribbon cost per foot $0.6 per foot
Answer:
Rounding to the nearest tenth and rounding to the nearest one hundredth.
Step-by-step explanation:
round all up or down then line up and add
12.568= 13
11.426= 11
12.324= 12
11.981= 12
12.601= 13
add the totals then you see
60.83 sames as 61
First, the total difference of the amount of people living in the town from 1998 to 2005 is 7945-5700 or 2245 people. To find out how many years it took for this growth, we would need to subtract 1998 from 2005 to get 7 years. So, in 7 years, the town gained 2245 people. If we divide 2245 by 7 to get the unit rate, we will find that the change in population is 320.71... people per year, or if rounded, 321 people per year, which is a.

Just took the quiz, Its Similar AA not sure why just trust me homie
Answer:
D(t) = 3 + 0.0(80 - t)
Step-by-step explanation:
The average of speed of Laura in miles per hour is given by:
S(t) = 6 + 0.1(80 - t) Equation 1
where, t is the temperature in degrees Fahrenheit.
The distance D, Laura covers at x miles per hour is given as:
D(x) = 0.5x Equation 2
We need to find the expression that models the distance that Laura runs in terms of the temperature "t"
The "x" in Equation 1 represents the average speed of Laura in miles per hour. S(t) in Equation 1 also represent the speed of Laura in miles per hour. So, we can replace x by S(t) in Equation 2 and generate an equation of Distance in terms of temperature "t" as shown below:
D(S(t)) = 0.5 (6 + 0.1(80-t))
D(t) = 3 + 0.0(80 - t)
This expression models the distance that Laura runs in 30 minutes given that it is t∘F outside at the start of her run.
