Answer:
C) 500:1
Step-by-step explanation:
As, 60/0.12= 60/12/100 = 6000/12
So, 6000/12 = 500/1
So, its 500/1
In a Petri dish there are currently 1,235 bacteria. The growth rate of bacteria is 3.25% How many bacteria will be there in the dish after 5 hours
Answer:
....
Step-by-step explanation:
Answer:
1,436
Step-by-step explanation:
First multiply the growth rate by the number of hours.
3.25 x 5 = 16.25
Now multiply 1,235 by 100. = 123,500
And also multiply 1235 by the remainder percentage not being used(83.75)= 103,060.75
Now subtract 123,500 - 103,060.75 = 20,439.25
Divide this number by 100 = 204.3925 which is what 16.25% of 1,235 is.
1,235 + 204 = about 1,439 but since i rounded up a few times the answer is actually 1,435.6875 rounded up to 1,436
3. The variance of a set of positive numbers p.(p-5).(p-2), (p-3) (2p-5)is 5.84.
(a) Calculate the value of p.
Answer:
(a) p = 7
Step-by-step explanation:
The given parameters are;
p, (p - 5), (p - 2), (p - 3), and (2·p - 5) is 5.84
(a) Therefore we have;
The mean of the numbers = (p + (p - 5) + (p - 2) + (p - 3) + (2·p - 5))/5 = (6·p - 15)/5
The mean of the numbers = (6·p - 15)/5 = 6/5·p - 3
Using an online tool, we have;
The variance = (p - (6/5·p - 3))² + ((p - 5) - (6/5·p - 3))² + ((p - 2) - (6/5·p - 3))² + ((p - 3) - (6/5·p - 3))² + ((2·p - 5) - (6/5·p - 3))²/5 = 4/25·p² - 4/5·p + 18/5 = 5.84
Therefore, we have;
4/25·p² - 4/5·p + 18/5 = 5.84
4/25·p² - 4/5·p + 18/5 - 5.84 = 0
4/25·p² - 4/5·p - 2.24 = 0
Using the quadratic formula, we have;
p = (4/5 ± √((4/5)² - 4× 4/25×(-2.24)))/(2 × 4/25)
Which gives;
p = 7, or p = -2
Given that the numbers are positive, we have the only solution as p = 7

Complete question
Consider these numbers, ordered from least to greatest. Negative 1.8, negative 1 and one-fourth, negative 0.2, blank, one-half, 90 percent A number line going from negative 2 to positive 1. Which values could correctly fill in the blank? Select all that apply. 10% 1 -0.1 -1 One-fourth
step-by-step explanation
On the number line, numbers increase from left to right.
The blank is between -0.2 and 1/2.
Only numbers greater than -0.2 and less than 1/2 can fill the blank.
Range = -0.2<x<1/2
From the values given,
1) 10% = 10/100 = 1/10 = 0.1
-0.2<0.1<1/2
2) -0.2<1
But, 1>1/2
3) -0.2<-0.1<1/2
4) -0.2>-1
5) -0.2<1/4<1/2
Therefore, only 10%, -0.1, and 1/4 can fill in the blank correctly because they satisfy the range -0.2<x<1/2

Answer:
No it can'tright angle triangle
Step-by-step explanation:
2, 2, √4 can't make a right triangle
By Pythagoras theorem the square of two sides equal to the third side of the triangle.
2^2+2^2=(√4)^2
4+4=4

How make 6 dozens cookies
Answer:
6 Dozen
Shortening: 6/4
Granulated Sugar: 18/4
Beaten Eggs: 2/4
Vanilla Extract: 2/2
Butter Flavoring: 2/4
Salt: 2/2
Baking Soda: 6/2
Cake Flour: 4
Food Coloring x 2
Step-by-step explanation:
6 ÷ 3 = 2
3 Dozen
Shortening: 3/4
Granulated Sugar: 9/4
Beaten Eggs: 1/4
Vanilla Extract:1/2
Butter Flavoring: 1/4
Salt: 1/2
Baking Soda: 3/2
Cake Flour: 2
Food Coloring
--------------------------------------------------
Shortening: 3/4 x 2
Granulated Sugar: 9/4 x 2
Beaten Eggs: 1/4 x 2
Vanilla Extract: 1/2 x 2
Butter Flavoring: 1/4 x 2
Salt: 1/2 x 2
Baking Soda: 3/2 x 2
Cake Flour: 2 x 2
Food Coloring x 2
--------------------------------------------------
6 Dozen
Shortening: 6/4
Granulated Sugar: 18/4
Beaten Eggs: 2/4
Vanilla Extract: 2/2
Butter Flavoring: 2/4
Salt: 2/2
Baking Soda: 6/2
Cake Flour: 4
Food Coloring x 2
6 Dozen cookies make with;
The amount of Shortening = 3/2
The amount of Salt = 2/2 = 1
The amount of Granulated Sugar = 9/2
The amount of Baking Soda = 6/2 = 3
The amount of Beaten Eggs = 1/2
The amount of Vanilla Extract = 1
The amount of Cake Flour = 4
The amount of Food Coloring = 1
The amount of Butter Flavoring = 1/2
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
For, 3 Dozen cookies we use;
The amount of Shortening = 3/4
The amount of Salt = 1/2
The amount of Granulated Sugar = 9/4
The amount of Beaten Eggs = 1/4
The amount of Vanilla Extract = 1/2
The amount of Butter Flavoring = 1/4
The amount of Baking Soda = 3/2
The amount of Cake Flour = 2
The amount of Food Coloring = 1/2
Since, We have to calculate all amount of things for 6 dozen cookies.
And, 3 x 2 = 6
Hence, 6 Dozen cookies make with;
The amount of Shortening = 3/4 x 2 = 3/2
The amount of Granulated Sugar = 9/4 x 2 = 9/2
The amount of Beaten Eggs = 1/4 x 2 = 1/2
The amount of Vanilla Extract = 1/2 x 2 = 1
The amount of Butter Flavoring = 1/4 x 2 = 1/2
The amount of Salt = 1/2 x 2 = 1
The amount of Baking Soda = 3/2 x 2 = 3
The amount of Cake Flour = 2 x 2 = 4
The amount of Food Coloring = 1/ 2 x 2 = 1
So, 6 Dozen cookies make with;
The amount of Shortening = 3/2
The amount of Salt = 2/2 = 1
The amount of Granulated Sugar = 9/2
The amount of Baking Soda = 6/2 = 3
The amount of Beaten Eggs = 1/2
The amount of Vanilla Extract = 1
The amount of Cake Flour = 4
The amount of Food Coloring = 1
The amount of Butter Flavoring = 1/2

What is the domain of the function represented by the graph?
Answer: Choice C. [tex]x \ge -3[/tex]
============================================
Explanation:
The domain is the set of all allowed x inputs.
Here we see that x = -3 is the smallest x value possible as it is from the left-most point. The graph goes on forever to the right, so there is no largest x value. Effectively infinity is the largest x value even though infinity is not a number.
We can say the domain is [tex]-3 \le x < \infty[/tex] which can be simplified to [tex]-3 \le x[/tex] or [tex]x \ge -3[/tex]
In short: x can be -3 or larger.
What is the solution to -2( 1 - 4x ) = 3x + 8
Answer:
x = 2
Step-by-step explanation:
Given
- 2 (1 - 4x) = 3x + 8 ( distribute parenthesis on left side )
- 2 + 8x = 3x + 8 ( subtract 3x from both sides )
- 2 + 5x = 8 ( add 2 to both sides )
5x = 10 ( divide both sides by 5 )
x = 2

Each conversion factor has a value of 1, but changes units. That is, the value of the numerator is the same as the value of the denominator, but expressed in different units.
We choose the representation of the conversion factors to cancel units we don't want and give us units we do want.

In this diagram where is the line of reflection?
The line of reflection is the vertical line x = 1.
What is a reflection?A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.
The line of reflection is the vertical line passing through the midpoint of segment AA'.
Since A'(2,5) and A(-4,5) have the same y-coordinate, their midpoint is on the line y = 5.
Therefore, the line of reflection is the vertical line x = 1.
