Answer 1

Answer:

B= 21.195

Step-by-step explanation:

Inner circle area = 3.14×1.5×1.5=7.065

Outer circle area = 3.14× 3×3 = 28.26

3 is the radius of the outer circle

Area of the shaded portion is = area of outer circle - area of inner circle

28.26-7.065=21.195

Answer B= 21.195

What is the interquartile range of warrens data?

Answers

Answer:

Step-by-step explanation:

Answer:

To find the interquartile range, first arrange the values in the data set in ascending order:

0, 5, 5, 10, 10, 10, 15, 15, 15, 20, 20, 20, 25, 25, 30.

Because there are 15 values in the data set, the first quartile is the 4th value, which is 10, and the third quartile is the 12th value, which is 20.

interquartile range

third quartile – first quartile

20 – 10

The interquartile range of Warren's data is 10.

Special right triangles how do you solve them

Answers

The interior angles of any triangle must add up to 180° in measure. Right angles have measure 90°, so the missing angles in both triangles here have measure 45°.

In a 45°-45°-90° triangle, the legs and hypotenuse occur in a ratio of 1 : √2. This means

(1) x = 48 √2

(2) 88 = √2 x → x = 88 / √2 = 44 √2

You could also set up trigonometric equations to solve for x in each case:

(1) cos(45°) = 48 / x → x = 48 / cos(45°) = 48 / (1 / √2) = 48 √2

(2) cos(45°) = x / 88 → x = 88 cos(45°) = 88 (1 / √2) = 44 √2

Step-by-step explanation:

The interior angles of any triangle must add up to 180° in measure. Right angles have measure 90°, so the missing angles in both triangles here have measure 45°.

Select the correct answer.
A survey reveals that the sales of smartphones is increasing considerably. The average annual sales of smartphones, in million units, n years after the survey is conducted is modeled by function p below. The parameter b is an unknown positive base.

p(n)=1.7×b^n

Which statement is true about this situation?

A.
When the survey was initially conducted, the average sales of smartphones was 1.7 million units.
B.
If b = 1.02, the annual sales of smartphones will double in 2 years.
C.
If b = 1.45, the annual growth rate of the sales of smartphones is 145%.
D.
The average annual sales of smartphones increases by 1.7 million units every year.

Answers

Answer:

When the survey was initially conducted, the average sales of smartphones was 1.7 million units.

Step-by-step explanation:

The exponential equation is P ( n ) = 1.7 ( b )ⁿ , where n is the number of years and P ( n ) is the annual sales of smartphones and the initial sales of smartphones was 1.7 million units

What is exponential growth factor?

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

P ( n ) = 1.7 ( b )ⁿ

where , n is the number of years

And , P ( n ) is the annual sales of smartphones

Now , the value of b is the exponential growth factor

At the initial year , the number of smartphones sold is when n = 0

So , when n = 0

P ( 0 ) = 1.7 ( b )⁰

P ( 0 ) = 1.7 million units

Hence , the number of smartphones sold in initial year is 1.7 million units

The 25th term of the given arithmetic sequence is -19.

The given arithmetic sequence is 53, 50, 47, 44, 41.

What is an arithmetic sequence?

An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is an=a+(n-1)d

Here the first term of the sequence is a=53 and the common difference is

50-53=-3

Put, a=53, d=-3 and n=25 in the general form an arithmetic sequence, we get

a25=53+(25-1)×(-3)

= 53+24×(-3)

= 53-72

= -19

Therefore, the 25th term of the given arithmetic sequence is -19.

Step-by-step explanation:

Given data

The points are

M(-5,2) and N(5,2)

x1=-5

y1= 2

x2=5

y2= 2

The expression for the distance between two points is

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((5-(-5))²+(2-2)²)

d=√10²+0²

d=√100

d=10

The capacity of a container is the amount the container can hold.

A standard coffee mug has a capacity of 16 fluid ounces. If Annie needs to fill 26 mugs with coffee, how many total quarts of coffee does she need?

Annie needs 13 quarts of coffee. I know this because 1 US quart is 32 US fluid ounces. 16 fluid ounces multiplied by 26 mugs of coffee is 416 and then you convert 416 fluid ounces into 13 quarts.

Convert: 9 T = 18,000 lb
