Assuming that bob will use a circle with radius 1 unit,
then the area of the whole circle is A = pi R^2
A = 3.1416(1^2)
A = 3.1416
fraction of auto supplies = 120 / 3000 = 0.04
Area auto supplies = 3.1415(0.04) = 0.1257
formula for of a circular segment
A = 0.5r^2x
where x is the angle in radian
0.1257 = 0.5(1^2)x
x = 0.2513 rad
convert to degrees
x = 0.2513 rad ( 180 /pi)
x = 14.40 degrees
Answer:
See the graph below.
Step-by-step explanation:
The graph is vertically translated by 6.
f(x) + 6 is indicated by blue line.
Answer:
29 m
Step-by-step explanation:
The dashes mean that the lines are equal in length, so from this we can determine that the area marked 441 m² is a square.
Area of a square = x², where x is the length of 1 side.
Therefore, x = √441 = 21 m
Now we have a right-angled triangle with two legs of 20 m and 21 m. We need to find the hypotenuse (labelled ?). To do this, use Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse.
Therefore,
20² + 21² = c²
⇒ 400 + 441 = c²
⇒ 841 = c²
⇒ c = √841
⇒ c = 29
So the side marked ? on the diagram is 29
Answer:
So, after 6 months, they both have the same number of coins.
Step-by-step explanation:
Jack has 56 coins
Jill has 80 coins
Jack collect 12 coins per month
Jill collect 8 coins per month
Let after m months, they both have the same coin.
56 + 12 m = 80 + 8 m
12 m - 8 m = 80 - 56
4 m = 24
m = 6
So, after 6 months, they both have the same number of coins.
