Simply use the formula they give you. For question 6, 4 is the radius. So the area of the circle is 4pi. Now for seven you do the same thing, but they gave you the diameter instead and it’s a half circle. So try that one on your own. Let me know if you get stuck
Answer: I think it is 1572 sq feet
Step-by-step explanation:
Lxwxh
14x13x9=1638
Window is 4x4.5=18
Door 1 is8x3=24
Door 2 8x3=24
Since the doors and window are not included in what was painted you need to subtract those totals from the room.
So, 1638-18=1620
1620-48(two doors)=1572 sq feet
Answer: Our variable be z for fair admission and our required linear equation will be
Explanation:
Since we have given that
Cost per ticket for the rides =$1.50
Total amount she spent = $48.75
Let the total cost be y
Let the number of ride tickets be x
<u>a) Define your variable:</u>
Let the amount spent on fair admission be z
<u>b) Write a linear equation that can be used to determine the cost for ride tickets and fair admission:</u>
Our required equation will be
Here, number of ride tickets = 20
So,
So, the cost for fair admission = $18.75
Answer:
-20 - (-20) = 0
Step-by-step explanation:
Since the problem starts with a negative number, you need to find out how many units from 0 it is. Since it is 20 units away from 0 in the negative direction, you need to add 20 in the positive direction to make it 0. Subtracting a negative number makes it positive. 2 negatives make a positive, so the problem is stated (rearranged) : 20 - 20 = 0.
If she has 3 cheeses and wants to bring in cheese for 12 days she has 3 and splits it up into 12 days so thats 3/12 which is 0.25 per day
