An object is traveling around a circle with a radius of 10 cm. If in 20 seconds a central angle of 1/3 radian is swept out, what is the linear speed of the object?

Answers

The linear speed of the object is (1)/(6)

  • The Radius, r = 10 cm
  • The Fraction of Radius swept out = (1)/(3)
  • The distance = 10 / (1)/(3)
  • The distance covered = (10)/(3)

The linear speed :

  • Radius swept out ÷ time taken
  • (10)/(3) * (1)/(20) = (1)/(6)

The linear speed of the object is (1)/(6)

Firstly, we will find the distance covered by the object in the 20 seconds:

\text{angle}(in~radians)=\frac{\text{arch}}{\text{radius}}\Longrightarrow (1)/(3)=(d)/(10~cm)\iff d=(10)/(3)~cm

We must know that v=(d)/(\Delta t). So:

v=(d)/(\Delta t)\Longrightarrow v=((10)/(3)~cm)/(20~s)\iff \boxed{v=(1)/(6)~cm/s}

There are 42 students in a class.Each student walks to school or cycles to school or gets the bus to school.
There are 23 girls in the class.
10 of the girls walk to school.
6 of the boys cycle to school.
7 of the 11 students who get the bus to school are boys.
Find the number of these students who walk to school.
Your final line must say, Number who walk to school = ...​

Answers

Answer:

15 students walk to school

Step-by-step explanation:

42 - total students

42 - 23 = 19

----

23 girl students

19 male students

----

19 - 6 = 13

13 - 2 = 11

--

11 - 7 = 3

3 + 2 = 5

--

10 girls walk to school

5 boys walk to school

--

10 + 5 = 15

A mixture of 30 pounds of candy sells for $1.10 a pound. The mixture consists of chocolates worth $1.50 a pound and chocolates worth 90¢ a pound. How many pounds of the $1.50 chocolate were used to make the mixture?If x represents the pounds of $1.50 chocolates used, then which of the following represents the pounds of 90¢ chocolates used?

x
30 - x
30

Answers

Answer:

10 pounds of the $1.50 chocolate were used.

30 - x represents the number of pounds of the 0.90 chocolate used.

Step-by-step explanation:

30 * 1.10 = 1.5x + 0.9 (30 - x)

33 = 1.5x + 27 - 0.9x

0.6x = 6

x = 10

Answer:

30 - x
