Answer: 45
Step-by-step explanation:
Set up a number line with 1 60 and 100. To get from 100 to 1 you divide by 100 so you also do that to 60 then to get 1 to 75 multiply by 75 same with 0.6 which will be 45

A rectangular playground is to be fenced off and divided in two by another fence parallel to one side of the playground. Six hundred feet of fencing is used. Find the dimensions of the playground that maximize the total enclosed area. What is the maximum area?
Answer:
the smallest dimension = 100 ft
the largest dimension = 150 ft
Maximum Area = 15000 ft²
Step-by-step explanation:
let x represent length of one side and L represent length of adjacent side
so from the question
3x + 2L = 600
2L = 600 - 3x
L = (600 - 3x)/2
L = (600/2) - (3x/2)
L = 300 - (3x/2)
now Area of rectangle = L × x
Area = (300 - (3x/2)) × x
Area = 300x - 3x²/2
now we differentiate with respect to x and equate to 0 in other to find critical point
dA/dx ⇒ 300x/x - 3x²/x = 0
300 - 3x = 0
3x = 300
x = 300/3
x = 100
so we input value of x into our previous equation
Area = 300x - 3x²/2
= 300(100) - (3(100)²)/2
= 30000 - 15000
Area = 15000
also we input value of x in L = 300 - (3x/2)
L = 300 - (3(100))/2)
L = 300 - 150
L = 150
Therefore
the smallest dimension = 100 ft
the largest dimension = 150 ft
Maximum Area = 15000 ft²

Answer:
slope = m , m = rise / run rise = change in y run = change in x
Step-by-step explanation:
to find change in y just subtract the second y from the first , like thus,
P1=(-10,8) = (X1,Y1)
P2=(-15,-7) = (X2,Y2)
-7-8=-15= change in Y
to find the change in X just subtract the second x from the first, like thus,
-15-(-10) = -15+10 = 5
m= -15/5
m=-3

What is simple interest?Simple interest is the interest amount for a particular principal amount of money at some rate of interest.
Simple Interest is calculated using the following formula: SI = P × R × T, where P = Principal, R = Rate of Interest, and T = Time period.
Given
Case 1:
Principal p = $500
Time t = 3 years
Rate of interest r = 2%
Based on the given conditions
Simple Interest = [tex]\frac{prt}{100}[/tex]
= [tex]\frac{500(2)(3)}{100}[/tex]
= $30
Case 2:
Principal p = $250
Time t = 2 years
Rate of interest r = 3%
Based on the given conditions
Simple Interest = [tex]\frac{prt}{100}[/tex]
= [tex]\frac{250(3)(2)}{100}[/tex]

A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417 B. $1,427 9 × $88 = $802; 5 × $125 = $625; $802 + $625 = $1,427 C. $1,565 9 × $125 = $1,125; 5 × $88 = $440; $1,125 + $440 = $1,565 D. $2,982 5 + 9 = 14; $88 + $125 = $213; 14 × $213 = $2,982
Answer:
The correct answer is A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417.
Step-by-step explanation:
From the question,
A store has 5 rings and 9 bracelets for sale. If all 14 items sell, the amount of money the store will take in can be determined by summing up the total cost of the rings and the total cost of the bracelets.
First, we will determine the total cost of the rings
From the question, a ring cost $125
∴ 5 rings will cost 5 × $125
5 × $125 = $625
Hence, the total cost of the rings is $625
For the bracelets
From the question, a bracelet cost $88
∴ 9 bracelets will cost 9 × $88
9 × $88 = $792
Hence, the total cost of the bracelets is $792
The amount the store will take in will be $625 + $792 = $1417
Hence, if all 14 items sell, the amount of money the store will take in will be $1417.
The correct answer is A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417
Answer:
The correct answer is A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417.
