A microbiologist is growing bacteria cultures in the lab. After 5 minutes, a bacteria colony has 1.3 million organisms. After 12 minutes, the same colony has 41.5 million organisms. After 15 minutes, the colony has grown to 101.3 million organisms. Is this a proportional or non-proportional relationship?
Answers
Answer: Non proportional
Step-by-step explanation:
To know if the values given are proportional or not, we will use the formula:
y = kx
where
y = number of organisms
x = number of minutes
k = constant of proportionality
After 5 minutes, a bacteria colony has 1.3 million organisms. Using the formula, y = kx
1,300,000 = 5k
k = 1,300,000 / 5
k = 260,000
After 12 minutes, the same colony has 41.5 million organisms. Using y= kx
41,500,000 = 12x
x = 41500000 / 12
x = 3458333.8
After 15 minutes, the colony has grown to 101.3 million organisms.
y = kx
101,300,000 = 15k
k = 101,300,000 / 15
k = 6753333.8
It is a non-proportional relationship as the constant of proportionality is different for each.
the square root of 4/49
Answers
Answer:
[tex]\frac{2}{7}[/tex]
Step-by-step explanation:
Simplify the numerator and the denominator.
The square root of 4/49 is 2/7.
Given that a fraction 4/49 we need to find the square root of this fraction,
To find the square root of a fraction, you need to find the square root of both the numerator and the denominator separately. Let's apply this to the fraction 4/49.
Step 1: Find the square root of the numerator:
The numerator is 4. Taking the square root of 4 gives us √4 = 2.
Step 2: Find the square root of the denominator:
The denominator is 49. Taking the square root of 49 gives us √49 = 7.
Step 3: Form the new fraction:
The square root of the fraction 4/49 is (√4)/(√49), which is 2/7.
Therefore, the square root of 4/49 is 2/7.

Answers
Division is one of the four fundamental arithmetic operations. The number of days this cat food will last is 14 days.
What is Division?Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that each cat eats 1/4 of a tin of cat food each day. Therefore, the amount of food that two cats will eat in a day is,
= 2 × 1/4 of a tin of cat food each day
= 1/2 of a tin of cat food each day
Further, it is given that Sally buys 7 tins of cat food. Therefore, the number of days this cat food will last is,
= Total cat food / Cat food needed in a day
= 7tin of cat food / 1/2 of a tin of cat food each day
= 14 days
Hence, the number of days this cat food will last is 14 days.

Adam's music playlist contains songs he bought and songs his mother bought. The ratio of his songs to his mother's songs is 5:3. How could you complete the table of equivalent ratios?
Answers
Answer:
The ratio of the songs is 5:3
Step-by-step explanation:
This means that for every 5 songs Adam has, his mother has 3. We can do that in intervals of 5:3, with 10:6, 15:9, 20:12, and etc.
Write "15" in Adam's column and "24" in his mother's column.
In the given question, the table of equivalent ratios is missing. Please find the attachment of that table below.
Given ratio is:
The ratio of Adam's songs to his mother's songs,

Given f(x) = 3x + 2 andg(x) = -2x - 4, find h(x) = f(x) - g(x).
Answers
Answer:
h(x) = 5x+6
Step-by-step explanation:
h(x) = f(x) - g(x)
h(x) = 3x+2 - (-2x-4)
h(x) = 3x+2 + 2x+4
h(x) = 5x+6
All we need to do is plug in the equations for f(x) and g(x) into h(x)
Let's do it
f(x) = 3x + 2 and g(x) = -2x -4
h(x) = f(x) - g(x)
h(x) = (3x + 2) - (-2x - 4)
Combine like terms
(3x) - (-2x) → 3x + 2x → 5x
(+2) - (-4) → 2 + 4 → 6
Let's put them together
h(x) = 5x + 6

d+h=80
d=2h−10
d+h=80
h=2d+10
h=80−d
Answers
Answer: I believe the answer is C
The system of linear equations that represents the given situation is (d + h = 80) and (d = 2h - 10) and this can be determined by using the given data.
Given :
Duc and Hue baked cookies to help with their community's fundraiser. Duc baked 10 less than twice the number of cookies Hue baked. Together they baked 80 cookies.The following steps can be used in order to determine the system of equations models given situation:
Step 1 - Let the total number of cookies Duc baked be 'd' and the total number of cookies Hue baked be 'h'.
Step 2 - The linear equation that represents the total number of cookies Hue and Duc baked is:
d + h = 80
d = 80 - h --- (1)
Step 3 - The linear equation that represents that Duc baked 10 less than twice the number of cookies Hue baked is:
d = 2h - 10 --- (2)
Step 4 - Substitute the value of 'd' in equation (2).
2h - 10 = 80 - h
Step 5 - Simplify the above expression.
3h = 90
h = 30 cookies
Step 6 - Substitute the value of 'h' in equation (1).
d = 80 - 30
d = 50 cookies

Answers
Answer:
3/8
Step-by-step explanation:
7/8 - 1/2 = ?
First, we find the Least Common Denominator and rewrite the fractions with the common denominator.
(7/8 × 1/1) - (1/2 × 4/4)
= 7/8 - 4/8 = ?
Now that the denominators are the same, we can subtract the numerators.
7-4/8 = 3/8
This fraction can't be reduced since it is already in its simplest form. Therefore, 7/8 - 1/2 = 3/8

Use the number line to add −3/5 and 1 1/4.
Answers
Answer:
13/20
Step-by-step explanation:
You can write 1 1/4 as 5/4. Any fraction that has the same number in the numerator and the denominator equals 1. For example 4/4 = 1, 20/20 =1, 5/5 = 1 and so on.
I can rewrite 1 1/4 as 4/4 + 1/4 = 5/4
Now we want to add -3/5 and 5/4. We need a common denominator because the pieces of the fractions are not equal. The smallest number that 5 and 4 will go into is 20. Si U an going to write the two fractions with 20 as the denominator.
-3/5 = -12/20 I multiplied the top and the bottom of -3/5 with 4.
5/4 = 25/20 I multiplied the top and the bottom of 5/4 by 5
-12/20 + 25/20 = 13/20
A rock is thrown from the top of a ladder. The function

thrown a certain number of feet.
What is the height of the rock at 5 seconds?
Answers
Answer:
h'(t)=88
Step-by-step explanation:
h'(t)=d/dt (-16t x 2 + 120t + 10
h'(t)=d/dt (-32t + 120t + 10)
h'(t)=d/dt (88t + 10)
h'(t)=d/dt (88t) + d/dt (10)
h'(t)=88 + 0

Kendal bought x boxes of cookies to bring to a party. Each boxes contain 12 cookies. She decided to keep 2 boxes for herself. She brings 60 cookies to the party. What equation can be use to find the number of boxes, x kendal bought
Answers
Answer:
7 boxes
Step-by-step explanation:
Let x represent the amount of cookies that was brought to the party by Kendall
Each box contain 12 cookies
= 12 × x
= 12x
Kendall keeps 2 boxes for herself
= 12 × 2
= 24
Kendall has 60 cookies which she took to the party
Therefore the question can be represented as follows
12x = 24+60
12x= 84
Divide both sides by the coefficient of x which is 12
12x/12= 84/12
x= 7
Hence Kendall brought 7 boxes
