Answer:
28
Step-by-step explanation:
Here is the complete question used in answering this question :
Three-fourths of the boats in the marina are white. 4/7 of the remaining boats are blue , and the rest are red . If there are 9red boats, how many boats are in the marina?
We first have to determine the fraction of the boats that are red
1 - ( + )
1 -
1 -
1 - 1
= 9/28
so, 9/28 of the boats are red
let b represent the total number of boats
9/28 x b = 9
to find b, divide both sides of the equation by 28/9
b = 28
Answer:
I. 37+0.2m≤95
II. The greatest Distance you can drive each day is 290 miles.
Step-by-step explanation:
The cost of a car rental is $37 per day plus 20 cents per mile.
Let the number of miles driven be represented by m.
Therefore costs of miles driven
=20 cents X m =$0.2 X m= $0.2m
Total Cost Per day= Rental Cost + Cost of Miles Driven = 37+0.2m
Since the daily budget is $95, the total cost must be less than or equal to $95.
That is,
37+0.2m≤95.....(I)
This is the inequality that represents the greatest distance possible.
Next, we solve for m
37+0.2m≤95
0.2m≤95-37
0.2m≤58
m≤58/0.2
m≤290
The greatest Distance you can drive each day is 290 miles.
Answer:
100 ft^2.
Step-by-step explanation:
This is the Pythagoras theorem:
The area of the square on AB = sum of the other 2 squares.
= 36 + 64
= 100 ft^2.

Answer:
Leagnth = 11
Width = 5
Step-by-step explanation:
Simple. 5 which could be the width multiplied three times is 15. Subract 4 from it. You have 11. 11 x 5 = 55, your area.
