How long will it take for a certain population of fish to triple if the relative growth rate is 45% per year?
Answer:
n = 3 Year (Approx)
Step-by-step explanation:
Given:
Growth rate (r) = 45% = 0.45
Find:
Number of year for 3 times of population (n)
Computation:
Assume;
Current population = P
So,
New population = 3P
A = p(1+r)ⁿ
3P = P(1+0.45)ⁿ
3 = (1.45)ⁿ
n = 2.96 year
n = 3 Year (Approx)
find the number of inches needed to represent 300 miles if one fourth in =50 mi
Answer:
1.5 in
Step-by-step explanation:
if one quarter of an inch represents 50 mi then and we know 50 x 6 = 300 then you would need 6 fourths of an inch or one and a half inches.
Number 13 Find the measures of angles 1, 2, and 3.
Answer:
1. 37
2. 26
3. 26
Step-by-step explanation:
Subtracting 63 from 180, you find the linear pair, being 117 which helps find an angle in the lower triangle. The sum of all angles is 180, and to find 2, you subtract the known angles ( 180-(37+117)) which equals 26. Knowing the shape is a parallelogram, and the opposite sides are parallel, we can say 2 and 3 are congruent through the alternate interior angles theorem. 1 is found through applying the same theorem.
The slope of a line is -1/5, and the y-intercept is 5. What is the equation of the line written in general form?
x - 5y - 5 = 0
x - 5y - 25 = 0
x + 5y - 25 = 0
Answer:
x + 5y - 25 = 0
Step-by-step explanation:
Equation of line in slope intercept form is given as:
[tex]y = mx + b \\ \\ plug \: m = - \frac{1}{5} \: \: and \: \: b = 5 \\ \\ y = - \frac{1}{5} x + 5 \\ \\ 5y = - x + 25 \\ \\ x + 5y - 25 = 0[/tex]
Answer:
x + 5y - 25 = 0

The sum of the ages of two brothers is 37.7 years. The older brother is
7.9 years older than the younger brother. The line graphed on the
coordinate grid represents the first of two equations in a system of linear
equations that can be used to find their ages.
If the second equation is x+y=37.7 , which value is closest to x, the age of the older brother in years?
a. 8
b. 15
c. 23
d. 30
Answer: 15
Step-by-step explanation: because 7.5 is in the middle of 5 and 10 and it goes straight down to 15

what is the range of the function f(x) =4^x+1 when the domain is {-1,0,3}
Answer:
(1,∞){y|y>1}
Step-by-step explanation:
i hope that this is what you are looking for^_^
This is just a fancy way your teacher saying that when you have an equation y=[tex]4^{x}[/tex]+1, what is y when x=-1,0,3.
We just need to solve by substituting the x in respectively.
x=-1, y=[tex]\frac{5}{4}[/tex]
x=0, y=1
x=3, y=65
Hope this helped! Any questions just put it in the comments.
pls tell me how to do it
Answer:
1) 35
2) 125
Step-by-step explanation:
1)
angle adc = x
x+ 90 + 20 = 180 (triangke sum property)\
x = 180 - 110 = 70
angle bdc = 70/ 2 = 35 ( the median cuts the angle into 2)
2) cbd = x = 125
x + c + bdc = 180
x + 35 + 20 = 180
x = 180 - 55 = 125
I hope im right!!!
I dont really understand this so can someone help me please!

Tayler's mom purchased a savings bond for Tyler. One year after it was purchased, the value of the savings bond was $156. If the value of the savings bond increases by 4% after one year, what was the value of the bond when Tyler's mom purchased it? Explain or show your reasoning.
Answer: The value of the bond when Tyler's mom purchased it = $150
Step-by-step explanation:
Let x= Purchasing price of the bond.
Given: Rate of increase in its value = 4% = 0.04
Value of bond after one year = x+ 4% of x
= x+0.04x
= 1.04x
One year after it was purchased, the value of the savings bond was $156.
[tex]\Rightarrow\ 1.04x = 156\\\\\Rightarrow\ x=\dfrac{156}{1.04}\\\\\Rightarrow\ x=150[/tex]
Hence, the value of the bond when Tyler's mom purchased it = $150

CAN SOMEONE HELP ME PLEASE I GIVE POINTS
Answer:
Step-by-step explanation:
1. What do you remember about the slope of a line? 2. A ramp may not be steeper than 1:12. Draw a right triangle whose "rise" is 1 unit, and whose "run" is 12 units. 3. Set up a trig ratio and use it to solve for the maximum angle of elevation of the ramp. Round to the nearest hundred 4. The height of the door on your restaurant is 9.5 inches from the ground. Using the maximum angle of elevation possi what would the length of the ramp be (x)? What would the horizontal distance be (y)
I remember every thing it was so good j set ramp

Darius and Khadija are learning to play chess. Darius's ratio of wins to losses is 5 to 13. Khadija's ratio of wins to losses is 3 to 9. Who has the better winning record?
Answer:
Darius
Step-by-step explanation:
Darius has played a total of 18 games so divide that by the five wins and you can see how many wins he would get on average wich is 0.28. Khadija won 3 out of 12 games so he/she has 0.25 average

The cattle at the Hodges family farm are fed 6 bales of hay each day. The horses are fed 2/3 as much as the cattle. how many bales of hay are the horses fed each day ?
Answer:
4 Bales Of Hay
Step-by-step explanation:
First you need to split the total into thirds. To do this you divide 6 by 3
6/3 = 2
Then since there are two thirds, you multiply 2 by 2
2*2 = 4
So the final answer is 4

Answer:

Point O is a centroid of the triangle LMN. If OM=38 cm, what is MP?
a.) 114 cm
b.) 19 cm
c.) 57 cm
d.) 25.5 cm
9514 1404 393
Answer:
c.) 57 cm
Step-by-step explanation:
The centroid divides the median into parts with a 2:1 ratio.
OM : OP = 2 : 1
OM : MP = 2 : (2+1) = 2 : 3
As a fraction with MP on top, this is ...
MP/OM = 3/2
MP = (3/2)OM = 3/2×(38 cm)
MP = 57 cm

Comment on the answer choices
Often, you can eliminate a number of the choices in a multiple-choice question just by testing whether they are reasonable. Here, the longer part of a line segment has length 38, so the whole segment will not be shorter than that. The choices 19 and 25.5 make no sense.
The remaining choices are 114 cm and 57 cm. The former is 3 times the length of the given segment, which the drawing tells us is unreasonable.
The only reasonable choice offered is 57 cm.
