Uhm i’m not the best at this but i’ll give it a try . they would probably have to have one same number you should try pemdas maybe idk :( sowwy
Answer:
if it took her 14 hours to make a 30-inch scarf, we can assume it will take her to double that time to make a 60-inch scarf. 28 hours is double of 14, if she only knits one hour every day it will take her 4 weeks, 28 days is equal to exactly 4 weeks 28/7=4 weeks
Answer:
Change = $3.26
Step-by-step explanation:
Given the following data;
Cost of cereal = $3.29.
Cost of milk = $3.45.
Amount paid = $10.00
Total cost of items bought = $3.29 + $3.45 = $6.74
Change = Amount paid - Total cost of items purchased.
Substituting into the equation, we have;
Change = $10.00 - $6.74
Change = $3.26
Therefore, Beth need to give the customer a change of $3.26.
Answer: 12
EXPLANATION
An exponential function is in the form y = f(x) = a
· b^x
Given,
When x = 0, y = 3
When x = 1, y = 6
Therefore,
Since y = a · b^x
When x = 0, y = 3
3 = a(b^0)
Any value raised to the power of 0 = 1
Therefore a = 3
So the exponential function we are considering is rewritten
as y = f(x) = 3 · b^x
Since y = 3 · b^x
When x = 1, y = 6
6 = 3 · b^1
6 = 3b
3b = 6
Divide both sides of the equation by 3
3b/3 = 6/3
b = 2
So the exponential function we are considering is rewritten
as y = f(x) = 3 · 2^x
When x =2, y = r
To find the value of r
y = f(x) = 3 · 2^x
r = 3 · 2^2
r = 3 · 4
r = 12
Therefore, the value of r that will make the table a
representation of an exponential function is 12
