Only 3% of turtle hatchlings will live to become breeding adults. How many turtles must have been born if the current number of breeding adults is 1,200?

Answers

Answer:

116400 I believe not 100% sure tho

The total number of turtles born is 40,000.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, only 3% of turtle hatchlings will live to become breeding adults.

The current number of breeding adults is 1,200

Let the total number of turtles born be t.

Now, 3% of t=1200

3/100 ×t=1200

3t=120000

t=40000

Therefore, the total number of turtles born is 40,000.

State a number that would lie between -2.15 and -2.16 on the number line

Answers

some possibilities would include the following:

2.151, 2.152, 2.153, 2.154, 2.155, 2.156, 2.157, 2.158, 2.159

there are more possibilities, but these are the most simple answers you could give :) hope this helped!

A number that would lie between -2.15 and -2.16 on the number line are 2.151.

What is a number line?

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.

There are some possibilities would include the following:

2.151, 2.152, 2.153, 2.154, 2.155, 2.156, 2.157, 2.158, 2.159

therefore, the numbers that are between 2.15 and 2.16 are 2.151.

What is your hypothesis from the activity in the lesson? Will the shorter cylinder or taller cylinder have the larger volume? Or, will both cylinders have the same volume? Explain your reasoning using complete sentences. [Note: There is no wrong answer as long as you make a hypothesis and explain your reasoning using complete sentences.]

Answers

Answer:

Taller because it is bigger and more likely to have greater volume

Step-by-step explanation:

its correct 100%

The correct statement is,

''The taller cylinder have the larger volume than shorter cylinder.''

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Will the shorter cylinder or taller cylinder have the larger volume.

Since, We know that;

The volume of a cylinder is calculated by multiplying the area of the base by the height.

And, since the height of the taller cylinder is greater than the shorter cylinder, it is likely to have a larger volume.

Thus, The taller cylinder have the larger volume than shorter cylinder.

Pythagorean theorem :)

Answers

Answer:

A^2 + B^2 = C^2

Step-by-step explanation:

Your welcome!

Answer:

x = 13

Step-by-step explanation:

In order to solve this you need to know the Pythagorean theorem:

a^2 + b^2 = c^2

a - 1 side

b - 2nd side

c - hypoteneuse

Step 1: Find the missing side of the triangles

** Note both triangles are equal to each other as shown by the dashed line in both that signifies both sides are equal to each other, and the 90-degree angle there as well**

Solve:

17^2 + b^2 = 19^2

289 + b^2 = 361

361 - 289 = 72

√72 = √b^2

8.5 = b (approximately, to the tenth)

Step 2: Because both of the triangles are equal to each other, the missing side is equal to 8.5, but there are two of them, in order to determine x, you need to add both values together:

8.5 + 8.5 = 17  

Then you   subtract it from the base value: 31

31 - 17 = 13

Therefore, x = 13, as that is the remaining of the base.

Find the area of a circle whose area equals the half of the sum of the areas of two circles with radil 2 and 3.
13
5
6.5

Answers

Step-by-step explanation:

step 1. a circle with r = 2 has area of (pi)r^2 = (pi)(4) = 4pi

step 2. a circle with r = 3 has area of (pi)r^2 = (pi)(9) = 9pi

step 3. the area, A, of a circle is half the sum of the area of the circles with r = 2 and r = 3

step 4. A = (4pi + 9pi)/2 = 13pi/2 = 6.5(pi).

step 5. the answer is not 6.5 but is 6.5(pi) or 6.5 times pi.
