Answers

Answer: 4 and 1

Step-by-step explanation:

Both ∠4 and ∠1 are equal angles. Both the angles are beside a right angle and you can measure it. The other answers are over 90 degrees, or below 90. This is because they either combine a 90 degree angle with another angle, or that they are too small and obvious that they are not complementary.

Answer:

<2 and <4

complimentary <s add up to 90 °

4 16


A. b=2 to the h power

B. b=2 to the h power plus 1

C. b=2h

D. b=2h+1
sorry, it shows it a bit messed up. the number of hours is shown on the left side with the numbers directly below it. the number of bacteria is the second column.

Answers

Answer:

A. b = 2 to the h power

Step-by-step explanation:

For the table:

When:

h = 0, b = 1, so 1 = 2^0, 1 = 1

h = 1, b = 2, so 2 = 2^1, 2 = 2

h = 2, b = 4, so 4 = 2^2, 4 = 4

h = 3, b = 8, so 8 = 2^3, 8 = 8

h = 4, b = 16, so 16 = 2^4, 16 = 16

I got A. B=2 to the h power

(π = 3.14)

192.78 inches
246.78 inches
277.56 inches
331.56 inches

please help lol

Answers

Answer:

The answer is 192.78 inches

Step-by-step explanation:

An oval is formed by a rectangle with semicircles at each end. We can visualize this easily.

The length of the rectangle is 54 inches.

The width of the rectangle is 27 inches.

The perimeter of rectangle is =  

=  

= 162 inches

And because there are two semicircles, we can combine them to form a circle. So, perimeter of a circle is called a circumference.

The width of the rectangle forms the diameter, so its half will be the radius.

r =  

The circumference is given by :  

=  inches

Now as the described oval shape is a complete figure without lines inside, we will subtract the width of both sides of the rectangle from the complete perimeter.

The complete perimeter is =  inches

The inner edge perimeter will be =  = 192.78 inches
