Answer:
Base 12m Height 5m
Step-by-step explanation:
Area of a triangle formula A=1/2bh
30=1/2(x)(x-7)
2*30 = 1/2(x)(x-7)*2
60 = x^2 -7x
60 - x^2 + 7x = 0
-60 + x^2 -7x = 0
x^2 -7x -60 =0
x^2 + 5x -12x -60 = 0
x(x+5)-12x-60=0
x(x+5)-12(x+5)=0
(x+5)*(x-12)=0
x+5=0
x-12=0
x=-5
x-12=0
x=12
The final answer is: x= 12,5
get rid of the -5 because -5 does not make sense at a height so turn it into 5
Base: 12m
Height 5m
Answer:
- 197 popcorn bags
- 202 food trays
Step-by-step explanation:
Since the numbers are split evenly 5 ways, each stand gets 1/5 of the total:
(985 bags)/5 = 197 bags
(1010 trays)/5 = 202 trays
Each concession stand receives 197 popcorn bags and 202 food trays.
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
radius = √98
center = (5.9,6.7)
equation of the circle = ?
Step 02:
Equation of the circle
(x - a) ² + (y - b) ² = r ²
(a , b) = center
(x - 5.9) ² + (y - 6.7) ² = (√98) ²
(x - 5.9) ² + (y - 6.7) ² = 98
The answer is:
(x - 5.9) ² + (y - 6.7) ² = 98
I'm assuming you're subtracting. It would be 3.9. The second one would be 0.65.
Area ( If you know the circumference) :
C^2 / (4×3.14) Brackets are important!
So you have to type :
53.38^2/(4×3.14)
= 226.865
