Hi !

C₁ = 2π×r₁

C₂ = 2π×r₂

C₂ - C₁ = 2π×r₂ - 2π×r₁

= 2π(23cm - 16cm)

= 2×3.14×7

= 43.96 cm

≈ 44 cm

Good luck !

Answer:

44 cm

Step-by-step explanation:

r = 16,R = 23;2πR - 2πr

2π(R - r)

2 ×22/7(23 -16)

2×22/7×(7)

2×22=44cm...

Answer: it is 32.6

Step-by-step explanation:

The orginal number that Gavin was thinking of is 32.60.

Let the orginal number be represented with y

Gavin adds 9 to the original number: 9 + y

The answer is doubled: 2(9 + y)

The answer is 83.2: 2(9+y) = 83.2

In order to determine the value of y, take the following steps:

Divide both sides of the equation by 2

9 + y = 41.60

Subtract 9 from both sides of the equation

y = 41.60 - 9

y = 32.60

dividing equally to each people

A person got=50/6

=8.33

so each got 8.33

but practically we cannot give it 8.33 to each so we can give 8 to each

Answer: B

Step-by-step explanation:

∠a and ∠b are complementary angles. Complementary angles are two angles adjacent to each other that add up to 90°. We know this is true because of the 90° angle that is labelled.

Vertical angles are not adjacent to each other. They are across from each other, connected by the angle. They are equal in angles. It is clear that ∠a and ∠b are not equal in angles. Therefore, they are complementary angles.

Answer:

3.947

Step-by-step explanation:

7 wholes = 7

one half = 0.5

1 whole = 1

nine tenths = 0.9

7.5/1.9 ≈ 3.947

Answer:

840

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 14 - 7 = 21 - 14 = 7

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 7 , thus

[tex]a_{120}[/tex] = 7 + (119 × 7 ) = 7 + 833 = 840

Answer:

(-2.5, -3.5)

Step-by-step explanation:

In order to find midpoint, you must add both x coordinates then divide by two and add both y coordinates then divide by two.

1 + (-6) = -5

-5/2 = -2.5

1 + (-8) = -7

-7/2 = -3.5

Step-by-step explanation:

Well, does she earn this interest per month?? or is it per year.

4% of $1000 is $40 dollars

so it would take her 2 years (If this 4% is due every year. if not just change the "year" to months) to reach 80 dollars. She just needs 20 dollars which is half of the 40 she earns per year. half of a year is 6 months so the answer would be

Sonja would need to keep her 1000 dollars in the savings account for 2 and a half years to earn 100 dollars exact.

Answer:

The mean absolute deviation = 3.5°F

Step-by-step explanation:

The sum of the given temperatures, ∑T, is found as follows;

∑T = 66°F + 57°F + 61°F + 65°F + 54°F + 62°F + 59°F + 56°F = 480°F

The number of days, n, over which the temperature was tracked = 8 days

Therefore, the mean, [tex]\bar x[/tex], of the data set = ∑T/n = 480°F/8 = 60°F

The mean absolute deviation is given by the following formula;

[tex]Mean \ absolute \ deviation = \frac{\sum \limits_{i = 1}^{n} \left | x_i - \bar x \right | }{n}[/tex]

Therefore, we have;

66 - 60 = [tex]\left | 6\right |[/tex] = 6

57 - 60 = [tex]\left | -3\right |[/tex] = 3

61 - 60 =  [tex]\left | 1\right |[/tex] = 1

65 - 60 =  [tex]\left | 5\right |[/tex] = 5

54 - 60 =  [tex]\left | -6\right |[/tex] = 6

62 - 60 =  [tex]\left | 2\right |[/tex] = 2

59 - 60 =  [tex]\left | -1\right |[/tex] = 1

56 - 60 =  [tex]\left | -4\right |[/tex] = 4

The mean absolute deviation is therefore;

The mean absolute deviation = (6 + 3 + 1 + 5 + 6 + 2 + 1 + 4)/8 = 3.5°F.

Answer:

For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.

Step-by-step explanation:

The sales price is not predicted to increase by $1.1; it is predicted to increase by $110,000 because S is measured in hundred-thousands of dollars. The sales price will not decrease by $110,000; it is predicted to increase by $110,000.

A linear regression is represented as [tex]^\wedge y = mx + c[/tex].

The true option is:  E. For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.

Given that:

[tex]^\wedge S = 0.5 + 1.1L[/tex]

From the general linear equation, we have:

[tex]1.1 \to[/tex] The slope

[tex]0.5 \to[/tex] The y-intercept

The slope is the difference between the sales price of one listing and the next.

From the question, we understand that the listed amount is in 100,000's.

This means that there is an increment of [tex]\$1.1 \times 100000[/tex] between the sales price of concurrent listing

So, we have:

[tex]\$1.1 \times 100000 =\$110000[/tex]

From the list of given options (see attachment), we can then conclude that (e) is correct.

Hence, for each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.
