Answer:
Step-by-step explanation:
Given:
- The shipping charge for the entire order is five dollars
- $10 for each hat
- the total of the college order is less than $120
Let x is the number of hats the coach other, we have the inequality
5 + 10x < 120
<=> 10x < 115
<=> x < 115/10 = 11.5
So the maxinum hats the coach can other is 15.
To determine the amount of fencing needed to enclose the pool area, you will need to add 15 feet to both sides of both dimensions to find the new dimensions that will need enclosed.
28 feet + 15 feet + 15 feet = 58 feet
23 feet + 15 feet + 15 feet = 53 feet
The fence will need to be 2 x 58 + 2 x 53 or 222 feet long for the 53 feet by 58 feet area.
Answer:
1) 5
2) (3 , 24)
Step-by-step explanation:
Question 1
f(x) x= 1 2 * 5¹ = 10
f(x) x= 2 2 * 5² = 50
f(x) x= 3 2 * 5³ = 250
multiplicative rate of change = 50/10 = 5
check: 250/50 = 5
Question 2
f(x) = 2 * 4ˣ
(3 , 24) f(3) = 2 * 4³ = 2 * 64 = 128 ≠ 24
So first we divide 140 by 7 because our ratio is a total of 7 dollars to get 20
So we multiply both sides of the ratio by 20 to get a ratio of 40:100
We can check our answer and it is right because 100+40=140
