Formula for the area of a face of a cube: A = length x width
Let's find the area of one face.
A = 5 x 5
A = 25
Now, let's multiply the area of one face by 6 because a cube has 6 faces.
25 x 6 = 150
A = 150 square centimeters
Hope this helps! :)
So to start this off, we need to find the area of the playground. We can simply multiply 150*2 and 50*2, and we get 300 and 100. Add those together and we get 400m.
Now, we can identify the number of laps it takes. But first, we have to convert kilometers into meters. there are 1000 meters in 1 km, so we will use 1000 to find the answer
Now, we can do 1000/400 to find the answer, which is 2.5
Therefore, it will take Kerry 2.5 laps to skate around the entire park
Answer: 2.5 laps
Hope this helped!!! :D
|-2| + |-3| - (-6)
= 2 + 3 + 6 = 11 (answer)
7x-y-17=0
Step-by-step explanation:
Answer:
- x+y≤80; x≥8; y≥5
- see attached for a graph
- Twenty campers are doing water-based activities and 40 campers are doing ground-based activities.
Step-by-step explanation:
1. Let x and y represent the numbers of campers doing water- and ground-based activities, respectively.
x + y ≤ 80 . . . . . . a maximum of 80 campers can be accommodated
x ≥ 8 . . . . . . . . . . a minimum of 8 campers should be water-based
y ≥ 5 . . . . . . . . . . a minimum of 5 campers should be ground-based
