Answer:
2
Step-by-step explanation:
We can write a proportion to determine
42 people 6 people
---------------- = ----------------
14 boats x boats
Using cross products
42x = 6*14
42x =84
Divide each side by 42
42x/42 = 84/42
x = 2
They will need 2 boats
I think the answer is b and c but I’m not very sure
Answer:
10 its simple
Step-by-step explanation:
Answer:
Step-by-step explanation:
Height of the Cylinder= 30 feet
Diameter = 8 feet
Radius= Diameter/2 = 8/2 = 4 feet
The Amount of Metal Sheet used in constructing the tank is the Total Surface Area of the Tank.
Total Surface Area of a Cylinder =
radius = 7
the equation of a circle in standard form is
(x-a)² + (y-b)² = r²
where (a, b) are the coordinates of the centre and r is the radius
To obtain this form ' complete the square ' on both the x and y terms
x² + 2(1)x + 1 + y² + 2(3)y + 9 = 39 + 1 + 9
(x+1)² + (y+3)² = 49 ← in standard form
with centre (1, 3) and r = √49 = 7
