Answer:
The average speed of an aircraft carrier is 13.89 km/h.
Step-by-step explanation:
We have,
Distance covered by an aircraft carrier is 1000 km
Time taken by the aircraft to travel is 3 days.
It is required to find the average speed of the aircraft.
1 day = 24 hours
3 days = 72 hours
Average speed :
So, the average speed of an aircraft carrier is 13.89 km/h.
The goal amount of the student groups are given in percentages, which are fractions based on one hundred.
The flutist raised more money than the trumpeters
The difference in the amounts the student raised is $256.5
Reasons:
The amount the school band is raising for the trip = $9,500
Goal of the flutist = To raise 18% of the total amount
Goal of the trumpeters = 85% of the flutist's goal
Required:
The group that raise more money, given that their goals are met
Solution:
Given that the goal of the trumpeters trumpeters is 85% of the goal of the flutist, the flutist raised more money.
Required:
The difference in the amount raised by the students
Solution:
The amount raised by the flutist = 18% of $9,500 = 0.18 × $9,500 = $1,710
Amount the trumpeters raised = 85% of $1,710 = 0.85 × $1,710 = $1,453.5
The difference in the amount raised = $1,710 - $1,453.5 = $256.5
Answer:
141 meters squared.
Step-by-step explanation:
We can split this shape into 2 parts to make it easier for us. The first one is a 5 by 5 meter shape, which has an area of 25 meters squared. Then the second part is a 7 by 16 meter rectangle. This has an area of 116 meters squared. So, the shape has a total area of 141 meters squared.
13/3.25 is equal to 4. That means it's 4 bucks per 1 inch
4x + 1 = -5x -8
4x +5x = -9
9x = -9
x = -1
y=-4+1 = -3
x=-1 y=-3
