A colony of 1,000 bacteria doubles in size every 18 minutes. What will the population be 54 minutes from now? (show steps) - will give brainliest

Answers

Answer:

3000.24

Step-by-step explanation:

We know that every 18 min, the colony grows 1000, so to make it easy, the way i do it is that i find out how much  it grows per min

1000 / 18 = 55.56

Then, to find out how big it will be in 54 min, we just multiply

55.56 x 54 = 3000.24

So that will be the size of the colony in 54 min. I hope this helps :)

2. The measure of an interior angle of a regular polygon is 160 degrees. Find the number of sides in the
polygon

Answers

Answer:

18 sides

Step-by-step explanation:

(N x 180) - 360 = 160N

180N -360 = 160N

Question 10 (2 points)
Find the missing length.
a
2.1 cm
2.9 cm
I NEED HELPPPP PLSSSS ITS FOR A MASTERY TEST PLSSSS HELPPPP

Answers

Answer:

a = 2

Step-by-step explanation:

To find the missing length we can use the Pythagorean theorem. Also, because it's a right triangle it makes it the perfect candidate!

The Pythagorean Theorem states:

a^2 + b^2 = c^2

Next, we substitute the letters with our given numbers (keep in mind that c is the hypotenuse which is the side facing the right angle)

a^2 + 2.1^2 = 2.9^2

Finally, we solve our equation (hint: use the calculator if needed)

a^2 = 4 (your answer is not final yet. You have to take the square root of both numbers)

a = 2 (Now that's the final answer!)

What is the image of the point (9,7) after a rotation of 180 counterclockwise about the origin

Answers

you would just negate each value, so it would be (-9,-7). you can also double check on a calculator

The image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

Rotation of a point A(x, y) 180 counterclockwise about the origin produces an image at A'(-x, -y).

Hence, the image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)

The calculated length of V'B' in the reflection of triangles is (c) 5

How to determine the length of V'B'

From the question, we have the following parameters that can be used in our computation:

The triangle and the image

Also, we know that the triangles are reflected

The reflection transformation is a rigid transformation

This means that

V'B' = VB

From the figures, we have

VB = 5

So, we have

V'B' = 5

Hence, the length of V'B' is (c) 5
