Answer:
84.87sq ft
Step-by-step explanation:
Let ABC be the triangle and AD be the perpendicular on BC such that BD=DC=7ft.
Now, it is known that 


Now, in triangle ADC, we have




Now, area of the triangle=
=
=
Thus, area of the building is 84.87sq ft.
4.78 is 4.776 to the nearest hundred
Answer: I’m not rlly sure
Step-by-step explanation: not sure
if the area is 6 that means the square is 2 x 3. 2 x 3 x 4. that equals 24.
let me know how you did !
To solve this problem you must apply the proccedure below:
1. Let's call:
x: hot dogs.
y: hamburguers.
2. Then, you must make a system of equations, as below:
5x+4y=12.25 (i)
4x+5y=12.50 (ii)
3. Now, you can solve the system of equation as below:
5x+4y=12.25
x=(12.25-4y)/5
4x+5y=12.50
4((12.25-4y)/5)+5y=12.50
y=1.5
4x+5y=12.50
4x+5(1.5)=12.50
x=1.25
4. Therefore, the answer is:
The cost of one hot dog is $1.25 and the cost of one hamburguer is $1.50
