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?
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.
3(5x + 2) = -5(3x - 5) + 3x
Answer:
x=19/27
Step-by-step explanation:
[tex]3(5x+2)=-5(3x-5)+3x\\15x+6=-15x+25+3x\\15x+6=-12x+25\\27x=19\\x= 19/27[/tex]
Hope this helps plz hit the crown :D
[tex]3(5x+2)=-5(3x-5)+3x[/tex]
Distribute 3 in 5x+2 and -5 in 3x-5
[tex]15x+6=-15x+25+3x[/tex]
Multiplying 2 negatives will be positive (Same goes to dividing 2 negatives.)
[tex]15x+15x-3x=25-6[/tex]
Move the x term to the same side and constant term to the same side.
(Whenever you move to another side, change the sign/operator to opposite. From plus to minus and from multiply to divide.)
[tex]27x=19\\x=\frac{19}{27}[/tex]
Thus, the answer is 19/27

Kenise will begin college as a freshman next fall and has received a 10-year $5,500 Federal Direct Unsubsidized Loan with an interest rate of 6.8%. She will be required to begin making payments six months after graduation. How much interest will accrue while she is still in school and over the six-month grace period?
Answer:
The interest accumulated will be $3,927
Step-by-step explanation:
Mathematically;
Simple interest = PRT/100
From the question, we have P as the amount borrowed = $5,500
R is the interest rate = 6.8%
T is the time which is 10 years + 6 months = 10 1/2 years
The interest accrued will thus be;
(5,500 * 6.8 * 10.5)/100 = $3,927

During one hour at an amusement park, 20 guests bought only day passes, 60 guests
bought only tickets to individual rides, and 40 guests bought only food.
What percentage of these 120 guests bought only day passes during this hour?
A 80%
B 20%
C %
D %
Answer:
the percentage of these 120 guest purchase only day passes is 16.67%
Step-by-step explanation:
The computation of the percentage of these 120 guest purchase only day passes is shown below
= Number of guests purchased only day passes ÷ Given guest
= 20 ÷ 120 guest
= 16.67%
Hence, the percentage of these 120 guest purchase only day passes is 16.67%

At Open Skate Night, admission is $3.75 with a membership card and $5.00 without a membership card. Skate rentals are $3.00. The Moores paid $6 more for skate rentals than the Cotters did. Together, the two families paid $42 for skate rentals. How many pairs of skates did the Moores rent? The Moores rented 9 pairs of skates.
Answer: 8 skates
Step-by-step explanation:
Given that:
Skate rental = $3
Let number of skates rented by cotters = x
Hence, amount paid by cotters = 3x
The Moores paid $6 more
Moores amount = 3x + 6
Combined amount paid = 42
3x + 3x + 6 = 42
6x + 6 = 42
6x = 42 - 6
6x = 36
x = 36 / 6
x = 6
Hence, amount spent by the Moore's:
3x + 6
3(6) + 6 = 18 + 6 = $24
Cost per skate rental = $3
Hence x number of skates rented by the Moore's = $24 / 3 = 8 skates

The x-intercept and y-intercept of the line are at (0, -1/2) and (1/4, 0). Then the correct option is C.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
y = 2x - 1/2
At x = 0, the value of the variable 'y' will be given as,
y = 2(0) - 1/2
y = - 1/2
At y = 0, the value of the variable 'x' will be given as,
0 = 2x - 1/2
2x = 1/2
x = 1/4
The x-intercept and y-intercept of the line are at (0, -1/2) and (1/4, 0). Then the correct option is C.

Across the top we have x+3 since the square has side length x and the long rectangles have their short side equal to 1. Three of those rectangles combined like that make 1+1+1 = 3
Across the far left side, we have a vertical distance of x combined with just 1 this time (instead of 3) leading to x+1

the square root of 4/49
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.

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?
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,
5:3then,
→ [tex]\frac{Adam's \ songs}{Mother's \ songs} =\frac{5}{3}[/tex]
→ [tex]Adam's \ songs = \frac{5}{3}\times 9[/tex]
