1 guest = 500ml
7 guests = 500ml × 7 = 3500ml = 3.5litres
1 litre = $1.50
0.5 litre = $1.50 ÷ 2 = $0.75
3.5litres = $1.50 + $1.50 + $1.50 + $0.75 = $5.25
answer is $5.25
2/3 miles in 1/12 of a hour
We need twelve 1/12 to make a whole hour
(2/3)•12 = 24/3= 8 miles
8 miles per hour
The ice cream cone consists of a semi-circle with a diameter of 10 cm and a triangle with a base of 10 cm and height of 12 cm.
The area of a semi-circle is half the area of a full circle, so we can find it by using:
If the diameter of the circle is 10 cm, then the radius is 5 cm. Plug in the known values:
or about 39.25
The area of a triangle is:
So we can plug in the known values to find the area to be:
When we add the areas of the two sections together, we get an exact answer of:
(60 + 12.5pi) cm^2
or about
99.25 cm^2
Answer:
If a shape is a square, then it is a quadrilateral
Step-by-step explanation:
Quadrilateral means four sided shape, so automatically, because a square has 4 sides, you know it is a quadrilateral. But not all quadrilaterals are a square, you could have a rectangle which is four sides so you know that this statement is wrong "If a shape is a quadrilateral, then it is a square." Therefore, the answer is "If a shape is a square, then it is a quadrilateral
Answer:
The magnitude of the necessary lifting force is 7.95N
Step-by-step explanation:
Force = mv^2/r
mass (m) = 2.00105kg, velocity (v) = 123m/s, radius (r) = 3810m
Force = 2.00105×123^2/3810 = 30273.89/3810 = 7.95N
