While catching fireflies, you and a friend decide to have a competition. after mm minutes, you have (3m+13)(3m+13) fireflies and your friend has (4m+6)(4m+6) fireflies.
a. how many fireflies are caught each minute during the competition?
To find for the number of fireflies caught in a minute, we simply look at the equation. The equation is linear and takes the form y = slope * x + b
where slope is also equivalent to the fireflies caught each minute.
So the equation of you and your friend is: (where y is the total fireflies caught)
you:
y = 3 m + 13
your friend:
y = 4 m + 6
So the fireflies caught each minute is:
you: 3
your friend: 4
So a total of 7 fireflies each minute combined

WILL GIVE BRAINLIEST-The number of pollinated flowers as a function of time in days can be represented by the function.
f(x)=(3)x/2
What is the average increase in the number of flowers pollinated per day between days 4 and 10?
Enter your answer in the box.
Final answer:
The average increase in the number of flowers pollinated per day between days 4 and 10 is calculated by finding the values of the function on days 4 and 10, subtracting these values, and dividing by the number of days between 4 and 10. The result is an average increase of 39 flowers per day.
Explanation:
Calculating the Average Increase in Pollinated Flowers
To find the average increase in the number of flowers pollinated per day, we need to evaluate the function f(x) = (3)x/2 at days 4 and 10 and then find the difference between these two values. First, let's calculate the number of flowers pollinated on day 4.
f(4) = (3)4/2 = (3)2 = 9
Now, let's calculate the number of flowers pollinated on day 10.
f(10) = (3)10/2 = (3)5 = 243
The difference between these two values is:
243 - 9 = 234
Lastly, to find the average increase per day between days 4 and 10, we will divide this difference by the number of days between 4 and 10, which is 6 days (10 - 4 = 6).
Average increase per day = 234 / 6 = 39
Therefore, the average increase in the number of flowers pollinated per day between days 4 and 10 is 39 flowers.

When four basketball players are about to have a free-throw competition, they often draw names out of a hat to randomly select the order in which they shoot. What is the probability that they shoot free throws in alphabetical order? Assume each player has a different name.
P(shoot free throws in alphabetical order) = _____
The total number of possibilities of drawing their names is given by permutation.
4P4 = 24
The total possibility of drawing their names in alphabetical is only 1.
Therefore the probability is:
P = 1 / 24
P = 0.0417
Therefore there is about 4.17% chance that it will be in alphabetical order
What is the equation of a line that is parallel to −x+3y=6 and passes through the point (3, 5) ? Enter your answer in the box.
Write an equation of the line passing through each of the following pairs of points.
a) (−10, 4), (2, −5)
b) (5, 7), (−6, −3)
The required equation of the line passing through the coordinates (−10, 4), (2, −5) is 4y+3x = -14
The required equation of the line passing through the coordinates (5, 7), (−6, −3) is 11y-10x = -27
The formula for finding the equation of a line is expressed as:
[tex]y-y_0=m(x-x_0)\\[/tex]
Given the coordinates (−10, 4), (2, −5)
Get the slope:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{-5-4}{2-(-10)} \\m=\frac{-9}{12}\\m=\frac{-3}{4}[/tex]
Get the required equation
[tex]y-4=-3/4(x+10)\\4(y-4)=3(x+10)\\4y-16=-3x-30\\4y + 3x = -30+16\\4y+3x = -14\\[/tex]
b) For the equation of the line with the coordinates (5,7) and (-6, -3)
Get the slope
m = -3-7/-6-5
m = -10/-11
m = 10/11
The required equation will be:
y - 7 = 10/11(x-5)
11(y-7) = 10(x-5)\
11y - 77 = 10x - 50
11y - 10x = -50 + 77
11y - 10x = -27
Hence the required equation of the line passing through the coordinates (5, 7), (−6, −3) is 11y-10x = -27

The formula for the area of a triangle is a=1/2bh. solve the formula for h. a triangle has a base of 7cm and an area of 28cm squared. what us it's height
Answer: 8 cm
Step-by-step explanation:
Given : The formula for the area of a triangle is [tex]a=\dfrac{1}{2}bh[/tex]
If a triangle has a base of 7 cm and an area of 28 cm squared.
The substitute the values of b = 7 and a = 28 in the above formula, we get
[tex]28=\dfrac{1}{2}(7)h[/tex]
Divide 7 and multiply 2 on on both sides, we get
[tex]h=\dfrac{28\times2}{7}=4\times2=8\ cm[/tex]
Hence, the height of triangle = 8 cm

I believe that the question is asking which one is false (as all the other are true).
Angles 2 and 3 are not congruent, because they are next to each other (not vertical angles). Rather, they are supplementary angles, meaning they would add up to 180° in measurement.

Alberto, Carlos and Maria share an inheritance of $54000 in the ratio of 3: 4: 5
What fraction of the the money does Alberto get?
Alberto gets [tex]\( \frac{1}{4} \)[/tex] of the inheritance.
To find out the fraction of the money Alberto gets, we first need to find out how much of the total inheritance each part of the ratio represents.
The total parts in the ratio are [tex]\(3 + 4 + 5 = 12\)[/tex].
Alberto's share is [tex]\(3\)[/tex] parts out of [tex]\(12\)[/tex].
So, Alberto's share of the inheritance is [tex]\( \frac{3}{12} \)[/tex] of the total amount.
To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is [tex]\(3\)[/tex]:
[tex]\( \frac{3}{12} = \frac{1}{4} \)[/tex]
Therefore, Alberto gets [tex]\( \frac{1}{4} \)[/tex] of the inheritance.
Leon drew Triangle ABC and Triangle DEF so that Angle A is congruent to Angle D, Andgle B is Congruent to Angle E, AB = 4, and DE = 8. Are Triangle ABC and Triangle DEF similar? If so, identify the similarity postulate or theorem that applies.
Answer:
The correct option is D
Step-by-step explanation:
Given triangle ABC and triangle DEF so that ∠A≅∠D, ∠B≅∠E, AB = 4, and DE = 8. we have to tell the similarity theorem or postulate that applies to prove above triangles congruent.
In ΔABC and ΔDEF
∠A=∠D (Given)
∠B=∠E (given)
Two angles are congruent
Hence, by AA similarity postulate which states that if the two corresponding angles of two triangles are congruent they are similar i.e ΔABC~ΔDEF
Hence, The correct option is D
What is the repeating decimal 0.242424.... as a fraction in simplest form?
A repeating decimal is a decimal that has reoccurring numbers in a particular sequence.
The fraction in the simplest form is 8/33
The decimal is given as:
[tex]Decimal = 0.242424....[/tex]
The repeating numbers in the decimal are 2 and 4.
So, we express the number as follows (as a fraction)
[tex]Fraction = \frac{24}{100}[/tex]
Subtract 1 from the denominator
[tex]Fraction = \frac{24}{100 -1}[/tex]
[tex]Fraction = \frac{24}{99}[/tex]
Reduce the fraction by dividing the numerator and the denominator by 3
[tex]Fraction = \frac{24/3}{99/3}[/tex]
Simplify
[tex]Fraction = \frac{8}{33}[/tex]
Hence, the fraction is 8/33

Staci is attending a music festival. The ticket to the festival costs 87.96. Staci plans to purchase 30.00 t-shirts from the event for close friends. She is taking 200.00 to the festival . What is the maximum number of t-shirts Staci can purchase?
Final answer:
Staci can purchase a maximum of 3 T-shirts after buying her festival ticket, given she brings $200.00 and each T-shirt costs $30.00.
Explanation:
To calculate the maximum number of T-shirts Staci can purchase at the music festival, we can follow these steps:
Subtract the cost of the festival ticket from the total amount of money Staci is taking to the festival. This will give us how much money she has left for the T-shirts.
Divide the remaining amount by the cost of one T-shirt to find out the maximum number of T-shirts she can buy.
So for the first step:
Staci has $200.00 and the ticket costs $87.96, leaving her with $200.00 - $87.96 = $112.04.
For the second step:
Each T-shirt costs $30.00, so we divide $112.04 by $30.00, which gives us 3.734.
Since Staci cannot buy a fraction of a T-shirt, we round down to the nearest whole number, which is 3.
Therefore, the maximum number of T-shirts Staci can purchase is 3.
