The sum of angle around a point equal 360°
so (BOA) = 360-250=110°
and the sum of angle in the shape CAOB = 360°
so BCA = 360-(110+90+90)= 70°
THE ANSWER IS C.70°

The diameter of a bicycle wheel is 63 cm. How much distance will it cover in 20revolutions?
alina1380 [7]

Answer:

1256 cm

Step-by-step explanation:

First we must find the perimeter, because the perimeter is equal to 1 revolution.

The perimeter of any circle is Pi(Diameter)

3.14*20

62.8 cm is the perimeter of the bike wheel.

Because the perimeter is basically a revolution, we can multiply 62.8 by 20 to get:

1256 cm

Cabs charge $3.60 Flag Fall plus $2.19 per km. (a) Write down an equation to calculate the cost, C, of cab fare for a distance d
Softa [21]

(a) C = 3.60+2.19d

(b) The cab fare will be $36.45 for a distance of d kilometers.

Step-by-step explanation:

Given,

Charges of Flag Fall = $3.60

Per kilometer charges = $2.19

Let,

d be the total distance.

C be the total cost for d kilometers.

(a) Write down an equation to calculate the cost, C, of cab fare for a distance d kilometres.

Total cost = Charges of flag fall + Per kilometer charges * distance

C = 3.60+2.19d

(b) Use your equation to calculate the cost of cab fare for a distance of 15 km.

Here,

d=15

Putting in Equation

C=3.60+2.19*15\\C=3.60+32.85\\C=36.45

The cab fare will be $36.45 for a distance of d kilometers.
