Answer 1
The formula for circumference = 2*Pi*r
R= radius. Radius is half of the diameter, and d= 20. This means that radius = 10. Now we have a full formula to work with.2*Pi*10.
Substitute 3.14 for pi.
3.14 * 10 = 31.4.
31.4*2 = 62.8.
62.8 rounded equals 63.
C = 63.

A drawing has a scale of 1 mm: 20 cm. What
is the scale factor of the drawing?

Answers

The scale factor of the drawing is 200.

Scale Factor of a Drawing

The first step to take when looking for the scale factor of a drawing is to ensure both measurements are on the same unit.

Given a scale for a drawing to be:  1 mm: 20 cm

1 cm = 10 m

Therefore:

20 cm = 200 mm

Scale factor = 200/1 = 200.

Therefore, the scale factor of the drawing is 200.

3 There are 5 times as many boys as girls in a school.
Together the school has 810 pupils.
How many boys are there?

Answers

Answer:

Number of boys = 675

Step-by-step explanation:

Given that:

There are 5 times as many boys as girls in a school.

Number of pupils in school = 810

Let,

x be the number of girls

y be the number of boys

According to given statement;

x+y=810      Eqn 1

y = 5x         Eqn 2

Putting y=5x in the Eqn 1

x+5x=810

6x=810

Dividing both sides by 6

[tex]\frac{6x}{6}=\frac{810}{6}\\x=135[/tex]

Putting x=135 in Eqn 2

y = 5(135)

y = 675

Hence,

Number of boys = 675

Answers

Answer:

a = 16

w = 125

x = 120

y = 55

Step-by-step explanation:

FINDING 'a'

31 = a + 46 / 2

62 = a + 46

16 = a

FINDING 'w'

* This section looks Non-Isosceles trapezoid so I will be following the rule according it

w + 55 = 180

w = 125

FINDING 'y'

y = 55

- Because of corresponding angles

FINDING 'x'

* In this case it looks like we are still dealing w/ an non-isosceles trapezoid.

x + 60 = 180

x = 120

Choose any number, say 20, and divide 729 by 20 ignoring any remainders. " 729/20 = 36 " Find the average of 20 and 36. 20 + 36 / 2 = 28. " Repeat the process until the estimate is the same as the quotient (until the remainder is 0). " 729 / 27 = 27.

Answers

Answer:

Answer is solved in the explanation below.

Step-by-step explanation:

Solution:

We have to repeat the process until the estimate is  the same as the quotient and remainder = 0. Which can be done only in the case of value = 27 (remainder = 0)

729/27 = 27 (remainder 0)

Let's I am starting this process from 19

So,

729 divided by 19 =  38.3684

Ignoring the remainders

729 divided by 19 = 38

Now, average of 19 and 38 = (19+38)/2 = 28

729 divided by 28 = 26.03

ignoring the remainders = 26

Now, average of 28 and 26 = (28+26)/2= 54/2 = 27

So,

729 divided by 27 = 27

Hence,

estimate is the same as quotient ( and remainder = 0)

Assuming the lines are evenly spaced between the integers, what number, in decimal notation, is represented by the plotted point?

Answers

Answer:

-1.4

Step-by-step explanation:

There are five increments between -2 and -1, so we find the difference between -2 and -1, which is 1. Divide 1 by five (increments)=.2

This means that every increment is worth 0.2.

If we see it from the left to right, from -2, there are 3 increments to the right, so multiply three by 0.2 which is 0.6, add 0.6 to -2, which is -1.4.
