A type of mold doubles every 9 hours. If you started with 14 spores in a Petri dish, how many spores would you have after 45 hours? After 45 hours, there would be_______spores.
Answers
Answer:
448
Step-by-step explanation:
Every 9 hours, mold doubles
Started with 14 spores
In 9 hours, 14+14= 28 spores
In 18 hours, 28+28=56 spores
In 27 hours, 56+56=112 spores
In 36 hours, 112+112=224 spores
In 45 hours, 224+224=448 spores
We want to write an equation for an exponential growth that represents the change in the population of mold.
The answer is: "After 45 hours, there would be__448__spores."
-----------------------------------
We know that a given type of mold doubles every 9 hours.
So if you start with a quantity A of spores, after 9 hours there are:
2*A spores.
After another 9 hours (for a total of 18 hours) the population is:
(2^2)*A spores.
You already could see the pattern.
After x hours, the number of spores will be given by:
p(x) = A*(2)^(x/9)
Now we want to know how many spores are there after 45 hours, if the initial amount is 14 spores.
So we need to replace:
A = 14x = 45Then we want to compute:
p(45) = 14*(2)^(45/9) = 448
From this, we can conclude that after 45 hours there will be 448 spores.

Answer:
Answer is 20 The simplified equation is 3+12+5
Step-by-step explanation:
since g =3 and h=6 we get 9/3 + 2(6) + 5 which makes 9/3= 3 and 2(6)=12 so it is simplified to 3+12+5 all added we get 20.

On a standardized multiple choice test, 3 points were awarded for a correct answer, while a wrong answer caused a deduction of 1 point, and no points were awarded or deducted for omitted questions If Marjorie received a score of 84 when she omitted 4 of the 40 questions on the test, how many did she get right? How many did she get wrong?
Answers
Answer: She got 30 questions right and 6 questions wrong.
Step-by-step explanation:
Let x = Number of correct questions, y = Number of wrong questions
As Award for each correct answer = +3 points and Award for each wrong answer = -1 point.
Total score = 3x-1y
If Marjorie omitted 4 of the 40 questions, then she did 40-4=36 questions.
Now, x+y = 36 (1)
and 3x-y =84 (2) (as she scored 84)
Adding (1) and (2), we get
4x = 120
Divide both sides by 4, we get
x= 30
y = 36-30=6
hence, she got 30 questions right and 6 questions wrong.

What are the dimensions of the outer rectangle in Leah’s scale drawing?
A. 3 3/8 x 5 5/8
B. 5 5/8 x 9
C. 6 3/4 x 5 5/8
D. 15 x 24
Answers
*see attachment for the scale drawing
Answer:
5⅝ in × 9 in
Step-by-step explanation:
Dimensions of the actual length = 15 ft by (9 + 6 + 9) ft
Dimensions of the actual length = 15 by 24 ft = 15 ft × 24 ft
Using the scale given as ⅜ in = 1 ft, let's find the dimensions of Leah's scale drawing of the outer rectangle.
Multiply each dimension in ft by ⅜ to get the dimension of the outer rectangle's scale drawing:
[tex] 15 * \frac{3}{8} = \frac{15*3}{8} = \frac{45}{8} = 5\frac{5}{8} [/tex]
[tex] 24 * \frac{3}{8} = 3 * 3 = 9 in [/tex]
Therefore, the dimensions of the scale drawing of the outer rectangle = 5⅝ in × 9 in

x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.

Which transformation can be used to show that LMN is similar to PQR?
A. Dilation, reflection
B. Reflection, translation
C. Rotation, dilation
D. Translation, rotation
Answers
Explanation:
Rotations, reflections and translations are known as rigid transformations; this means they do not change the size or shape of a figure, they simply move it. These rigid transformations preserve congruence.
Dilation, however, are not rigid transformations, since they change the size of a shape. Dilation would not change the shape, just the size; the angle measures would be the same, and the ratio of corresponding sides would be equal to the scale factor used in the dilation. This would give us a similar, but not congruent, figure.

During a promotional weekend, a state fair gives a free admission to every 188th person that enters the fair. On Saturday, there were 6,737 people attending the fair. On Sunday, there were 8,669 people attending the fair. How many people received a free admission over the two days?
Answers
Answer: 81 people
Step-by-step explanation:
Number of people that attended fair on Saturday = 6737
Number of people that got free admission = 6737/188 = 35.8.
Free admission on Saturday = 35
Number of people that attended fair on Saturday = 8669
Number of people that got free admission = 8669/188 = 46.1
Free admission on Sunday = 46
The people who received a free admission over the two days will be:

First things first, take off 10, 20, 50, and 60.
Now, you remain with 32 and 37. Now from here it is simple.
Average of 32 and 37 = 34.83
Round 34.83 to 35
32 averaging 37 (Rounding Terms) ≈ 35
So X is 27
