Answer:
5
Step-by-step explanation:
The answer is 5 because as you can see: 10/8, if you divide the 10 by 2 that would be 5. Same with the denominator, 8 divided by 2 is 4. So, your answer is 5/4. Or 5.
Step-by-step explanation:
Let assume that
Cost of 1 burger = $ x
Cost of 1 doughnuts = $ y
According to statement, 9 burgers and 1 doughnut cost $ 31.30
According to statement again, 3 doughnuts and 6 burgers cost $ 26.70
On substituting the value of y from equation (1), we get
So,
Cost of 2 burgers = 3.2 × 2 = <u>$ 6.4</u>
Answer:
Hydrostatic Force = 35.28KN
Step-by-step explanation:
To solve this question, let's consider integrating the hydrostatic force from the top of the triangle to the bottom.
Formula for a thin horizontal slice of the triangle the force is;
δF=ρgxwδx
Where w is width of triangle; ρ is density of water and g is acceleration due to gravity
At depth x, the width of the triangle is w=2/3x.
Thus, F = (3,0)∫)ρgxwδx
=(2/3)ρg[(3,0)∫)x²δx]
= integrating, we have;
F = (2/3)ρg[(3³/3) - (0³/3)]
F = (2/5)ρg [27/3] = (2/5)(1000)(9.8)(9) = 35280 N = 35.28 KN
Since annual means per year, then you need to divide 22 by 5.
5 / 22 = 4.4
Now lets check our work.
4.4 x 5 = 22
