Amara needs 45kilograms of meat to feed her 2pet dragons each day. Each pet dragon eats the same amount of meat.
How many kilograms of meat does Amara need to feed 4 pet dragons each day?
Answers
[tex]\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}[/tex]
She needs 45 kg meat for 2 pets
each pet feed the same, i.e,
one pet eats = 45/2 = 22.5 kg meat
then 4 pet dragons will eat = [tex] 22.5kg \times 4 = 90 kg [/tex] meat.
Hence, Amara needs 90 kilograms of meat to feed 4 pet dragons each day.

Select the correct answer.
Scientists studying biodiversity of amphibians in a rain forest have discovered that the number of species is decreasing by 2% per year. There are currently 74 species of amphibians in the rain forest. Which logarithmic function models the time, , in years, it will take the number of species to decrease to a value of n?
The answer is D.
Step-by-step explanation:
The logarithm function that models the time, f(n) , in years is [tex]\rm f(n) = log_{0.98} (\dfrac{n}{74})[/tex], the correct option is D.
What is an Exponential Function?An exponential function can be represented in the form f(x) = abˣ.
The number of species is decreasing by 0.02
Current number of species = 74
The time f(n) years is given by
f(n) = 74 (0.98)ⁿ
Converting exponent to logarithm form
x = aⁿ
y = logₓ a
f(n) = 74 (0.98)ⁿ
[tex]\rm f(n) = log_{0.98} (\dfrac{n}{74})[/tex]

Consider the equation Ax+By=−36. If the x-intercept is (−3,0) and the y-intercept is (0,9), what are the values of A and B?
Answers
Answer:
A= 12
B = -4
Step-by-step explanation:
( -3,0) & (0,9) should satisfy the equation Ax + By = -36
when ( -3,0)
-3A+ 0 = -36
A = 12
when (0,9)
0 + 9B = -36
B = -4
The value of A and B is 12 and -4.
Given that,
The equation is Ax + By = -36.And, the x-intercept is (-3,0) and the y-intercept is (0,9).Based on the above information, the calculation is as follows:
Ax + By = -36
When (-3,0)
So,
-3A+ 0 = -36
A = 12
Now
when (0,9)
So,
0 + 9B = -36
B = -4
Therefore we can conclude that the value of A and B is 12 and -4.

Answer:
y=2.50x+20
Step-by-step explanation
Slope intercept equation is = y=mx+b
So you BEGIN with 20, which is your membership fee (it only gets charged once) then your mx is your slope. 2.50 is your slope because they earn 2.50 for each (x) video rented.
you place a number beside the x for each video rented. For example, if you rent 2 videos then you write this y=2.50(2)+20

4n+2=(6)(

n)+(6)(

4n+2=2n+−4
4n+2=2n−4
Step 2: Subtract 2n from both sides.
4n+2−2n=2n−4−2n
2n+2=−4
Step 3: Subtract 2 from both sides.
2n+2−2=−4−2
2n=−6
Step 4: Divide both sides by 2.
2n

n=−3
Answer:
n = -3
Step-by-step explanation:
The first step you want to do is try to get rid of those parenthesis and to do that you want to distribute the 6 into 1/3n and 2/3 and you get
4n + 2 = [tex]\frac{6}{3}[/tex]n - [tex]\frac{12}{3}[/tex]
that can be simplified to
4n + 2 = 2n - 4
subtract 2n from both sides and you get
2n + 2 = -4
subtract 2 from both sides
2n = -6
divide both sides by 2 you get
n = -3
