A certain population of bacteria has an average growth rate of 0.06 bacteria per hour. The formula for the growth of the bacteria's population is = ࡼ (. ૠૡ) where, ࢚. Po is the original population, t is time in hours, and A is the new population . If the current population of a culture was 3000 bacteria (A) and it started growing 30 hours ago, what was the original size of the bacteria (Po)?
Answer:
522 bacteria
Step-by-step explanation:
The formula given as growth rate =
A = Po (1 + r)^t
Where:
Po is the original population
t is time in hours = 30
A is the new population = 3000
r is growth rate = 0.06
3000 = Po × ( 1 + 0.06)^30
3000 = Po × 1.06^30
Divide both sides by 1.06^30
Po = 3000/1.06^30
Po = 522.33039273 bacteria
Approximately = 522 bacteria
The original size of the bacteria was 522 bacteria

Use the distributive property to write an equivalent expression 6(2r-10s+2)
Answer: 12r-60s+12
Step-by-step explanation:
when distributing multiply what is outside the parenthesis * the inside numbers one by one.
6 * 2r = 12r
6 * -10s = -60s
6 * 2 = 12
Now put it all together
12r-60s+12
Aiguo places 6 circular biscuits, each with the same diameter, on a baking sheet as shown below. What is the approximate area of the baking sheet left uncovered? Please hurry!
Answer:
46cm²
Step-by-step explanation:
Find the diagram attached.
The area of the baking sheet left uncovered = Area of rectangle - Area of the 6 circular biscuits
Area of the rectangle = Length * Width
Given
Length = 12cm
Width = 18cm
Area of the rectangle = 12*18
Area of the rectangle = 216cm²
The diameter of one of the circle = Length/3
The diameter of one of the circle = 18/3 = 6cm
Area of a circle = πd²/4
Area of a circle = π(6)²/4
Area of a circle = 36π/4
Area of a circle = 9π cm ²
Area of the six circular biscuit = 6(9π) = 54πcm²
Area of the six circular biscuit = 54(3.14) = 169.56cm²
Area of the baking sheet left uncovered = 216 - 169.56
Area of the baking sheet left uncovered = 46.44cm²
Area of the baking sheet left uncovered is approximately 46cm²
Write the equation in slope intercept form for the line that passes through the points (-3,-10) and (5,14). Show
your work.
Answer:
67+67+98=833 SO MULTIPLY
Step-by-step explanation:
The equation of the line that passes through the points (-3,-10) and (5,14) will be y = 3x - 1.
What is the equation of a line passing through two points?Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).
Then the equation of the line is given as,
[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]
The two points are given below.
(-3,-10) and (5,14)
The equation of the line that passes through the points (-3,-10) and (5,14) will be given as,
y + 10 = [(14 + 10) / (5 + 3)](x + 3)
y + 10 = 3(x + 3)
y = 3x + 9 - 10
y = 3x - 1
The equation of the line that passes through the points (-3,-10) and (5,14) will be y = 3x - 1.

baroque history/ events
Answer:
Baroque is a particular style in architecture, music and the arts that was popular between the late 17th and mid-18th centuries, especially in Catholic countries.
It is characterized in architecture and drawing using flexible or dotted lines, floral and gilded ornamentation (which gave rise to the Rococo style) and spatial effects. Among the most important baroque artists could be mentioned Bernini, Borromini, Caravaggio and Rubens.
In music compositions by composers such as Johann Sebastian Bach and Monteverdi are associated with baroque music. This was the period that saw the development of the opera.
In literature, Baroque is a less definite and defined term. Picaresque novels of the period could be considered as an example. It was an important influence on the literature of the period as well, especially in France, Italy, southern Germany and Spain.
what is an equivalent fraction to -5/25
Answer:
stinkey monkey :3
The equivalent fraction to -5/25 will be -1/5. Since the value of both fractions is the same as a result represented as the equivalent fraction.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that the expression is, -5/25.
We have to find the equivalent fraction for the given expression.
Equivalent fractions are two or more fractions that, although having various numerators and denominators, are all the same. 1/5, for instance, is equal to -5/25. The fraction is always expressed in its simplest form, "one-fifth."
Thus, the equivalent fraction to -5/25 will be -1/5. Since the value of both fractions is the same as a result represented as the equivalent fraction.

HELP ASAP!!!!
Answer:
x=−1
Step-by-step explanation:
Let's solve your equation step-by-step.
5x−7−2x=−10
Step 1: Simplify both sides of the equation.
5x−7−2x=−10
5x+−7+−2x=−10
(5x+−2x)+(−7)=−10(Combine Like Terms)
3x+−7=−10
3x−7=−10
Step 2: Add 7 to both sides.
3x−7+7=−10+7
3x=−3

All the angles in a triangle will add up to 180 degrees.
Therefore, subtract all the given angles to find x.
180 - 20 -130 = 30
So the missing angle is 30 degrees.
Intro:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
We should know that the sum of all the angles in the triangle add up to 180. So since we already know two we can add those two and then subtract it from 180 to find the missing angle or I like to write equations...
[tex]20+130+x=180[/tex]
After we make an equation we would combine like terms...
[tex]150+x=180[/tex]
Now all we have to do is subtract 150 on both sides to get our missing angle...
[tex]x=30[/tex]
So the missing angle is 30°.
Which is a valid conclusion using the Law of Syllogism? a) If it is raining when we leave, I will open the umbrella. b) If I open the umbrella, you will see pink ducks. Group of answer choices If I open the umbrella, you will see pink ducks. If it is raining, you will see pink ducks. It is raining. You will see pink ducks.
Answer:
If it is raining when we leave, you will see pink ducks.
Step-by-step explanation:
The Law of Syllogism is defined by the following rule:
[tex]P\implies Q \,\land\,Q\implies R[/tex] (Eq. 1)
[tex]\therefore P\implies R[/tex]
Where [tex]P[/tex], [tex]Q[/tex], [tex]R[/tex] are propositions.
From statements we know that propositions are:
P = It is raining when we leave.
Q = I open the umbrella.
R = You see pink ducks.
By applying the Law of Syllogism we construct this compound proposition:
If it is raining when we leave, you will see pink ducks.

Answer:
294lbs
Step-by-step explanation:
You can find the weight by taking 10% of 280. (Move the decimal one spot to the left) That would be 28. Then divide 28 by 2 and you get 14, which would be 5%. Then add 14 to 280 and you get 294.
