A population of ants is 10,000 at the start of April. Since then, it triples each month.
Month since April Number of Ants
0
1
2
3
4
Answer:
Month since April Number of Ants
0 10,000
1 30,000
2 90,000
3 270,000
4 810,000
Every month, the ant population triples so the multiply the previous population by 3 to find out the new population.
0 months from April = 10,000 * 1 = 10,000 ants
1 month from April = 10,000 * 3 = 30,000 ants
2 months from April = 30,000 * 3 = 90,000 ants
3 months from April = 90,000 * 3 = 270,000 ants
4 months from April = 270,000 * 3 = 810,000
The combined height of one fir tree and one pine tree is 212121 meters. The height of 444 fir trees stacked on top of each other is 242424 meters taller than one pine tree. How tall are the types of trees that Logan genetically engineered?
Answer: The height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.
Step-by-step explanation:
Let x= height of each fir tree, y = height of each pine tree.
As per given, we have
x+y = 21 (i)
4x=y+24 (ii)
From (ii),
[tex]4x-y=24[/tex] (iii)
Add (i) and (iii), we get
[tex]5x=45\\\\\Rightarrow\ x=\dfrac{45}{5}\\\\\Rightarrow\ x=9[/tex]
Put value of x in (i), we get
[tex]9+y=21\Rightarrow y=12[/tex]
Hence, the height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.
Answer:
Each fir tree is 9 meters tall and each pine tree is 12 meters tall.

Find the measure of FEG 25,65,80,90
Answer:
First, you have to set 5x equal to (3x+10). They are vertical angles and therefore congruent.
5x = 3x+10 The variable should only be on one side of the equation,
5x - 3x = 10 Therefore subtract 3x from both sides
2x = 10 Divide by 2 on both sides.
x = 5
We're not done yet, since we've found the x-value we have to solve for ∠GEC.
∠GEC = 3x+10 = 3(5)+10 = 15+10 = 25°
∠GEC and ∠FEG form a right angle. This means that the sum of the two angles is 90°
90° = 25° + x In this case, we're using "x" to solve for ∠FEG
90-25 = x We subtract 25 from both sides to get the variable by itself.
65° = x
∠FEG = 65° The Answer is B

How much more would Keri's monthly loan payment be if she got a 5% loan for 5 years?
$
more per month
$9436 EMI Keri has to pay for $500,000 loan at the rate of 5% for 5 years.
What is EMI?equated monthly instalment or EMI relates to payments made regularly to repay an outstanding loan within a certain time frame.
Given loan rate is 5% and time period is 5 years let total amount is $500,000. Formula for EMI Calculation is -
P x R x (1+R)^N / [(1+R)^N-1] where-
P = Principal loan amount.
N = Loan tenure in months.
R = Monthly interest rate.
R = Annual Rate of interest/12/100.
Putting these values in above equation
EMI = 500000 *5* *(1 + 5%)^60 / [(1 + 5%)^60]
EMI = 9436
Therefore, Keri must pay a $9436 EMI on her $500,000 loan over five years at a rate of 5%

A.It represents the product of two irrational numbers and is equivalent to a rational number.
B.It represents the product of two irrational numbers and is equivalent to an irrational number.
C.It represents the product of two rational numbers and is equivalent to a rational number.
D.It represents the product of two rational numbers and is equivalent to an irrational number.
Answer:
A. is correct
Step-by-step explanation:
sqrt3*sqrt12 can be rewritten as √3·√12, which can be extended to
√3·√3·√4.
Note that √4 = 2 and that (√3)^2 = 3,
so the final result is 2*3, or 6 (a rational number).
A. is correct: √3 and √12 are both irrational, but their product is rational.
A certain brand of shampoo contains 12 ounces in a bottle. The company
decides to redesign the shape of the shampoo bottle. The new type of
bottle contains 15 ounces of shampoo. What is the percent of increase in
the amount of shampoo the new bottle contains?
Answer: 15% I think
Step-by-step explanation:
The percent of increase in the amount of shampoo the new bottle contains is 25%.
Given that, a certain brand of shampoo contains 12 ounces in a bottle and the new type of bottle contains 15 ounces of shampoo.
What is the percentage of increase?Percentage increase is the difference between the final value and the initial value, expressed in the form of a percentage.
Percentage increase = (Final value - Initial value) / Initial value × 100
Now, initial value = 12 and final value = 15
Percentage increase = (15-12)/12 × 100
= 3/12 × 100
= 1/4 × 100
=25%
Therefore, the percent of increase in the amount of shampoo the new bottle contains is 25%.

A rectangular window is 3ft long and 2ft wide. Kala would like to buy a screen for the window. The cost of the screen is based on the number of square inches the screen is. Use the facts to find the area of the window in square inches.
Answer:
The cost of screen for window = 864.
Step-by-step explanation:
We have,
A rectangular window of length = 3ft and breadth 2 ft.Fir solving,
As the answers should be in sqaure inches let us first convert ft in inches.Then, we will find the area of window and as the cost of screen is same as that of area,we will find it.★Conversion from ft to inches:
We kow that,
1 foot = 12 inchesTaking this in mind, convert the values
= Length = 3 ft
= Length = 3 × 12
= Length = 36 inchees
= Breadth = 2ft
= Breadth = 2 × 12
= Breadth = 24 inches
★Area of window:
We know that,
= Area of rectangle = Length × Breadth
= Area = 36 × 24
= Area = 864 inches²
As, area of window in square inches equal to cost of the screen.
Therfore, cost of screen would be 864.
__________________________Two siblings ' ages have a sum of 64 years . The older sibling was born 6 years before their young sibling . Write a system of 2 equations . Solve the system using substitution . Report your answer in the form of ( older , younger ).
Answer:
younger sibling = 29 years
older sibling = 35 years
Step-by-step explanation:
Let
x = younger sibling
y = older sibling
x + y = 64 (1)
The older sibling was born 6 years before their young sibling
x = y - 6 (2)
Substitute x = y - 6 into (1)
x + y = 64
y - 6 + y = 64
2y = 64 + 6
2y = 70
y = 70/2
y = 35 years
Substitute y = 35 into (2)
x = y - 6
x = 35 - 6
x = 29 years
