Answer:
1200 i think
Step-by-step explanation:
i used a calculator since its hard for me to do mental math
question 2
(sorry i replied late i was doing some of my school work)
so you make A be equal to 5000 since you want to know when his account will be that much money sooo
5000 = 2000(1.07t)
you divide 2000 from both sides
5000/2000 = 1.07t
5/2 = 1.07t
now you have to isolate t to solve for it
soo divide 1.07 to both sides
5/2 / 1.07 = t
t is equal to about 2.34 or 2 years (depends on what it tells you to round to) in the calc t is 2.336448598
so in maybe 2 years he'll have 5000 dollars

We see : 4x - 5y = -20
We can write the negative form of 4x - 5y by switching the signs : - (4x - 5y ) = -4x + 5y
Since -4x + 5y is the negative form of 4x - 5y, the result should also be the opposite : 20
And -4x + 5y is indeed 20, so the answer is infinitely many solutions.
Answer:
infinitely many solutions
Step-by-step explanation:
4x - 5y = - 20 → (1)
- 4x + 5y = 20 → (2)
add (1) and (2) term by term
0 + 0 = 0
0 = 0 ← true statement
this indicates the system has infinitely many solutions
Write the equation of the line that goes through the points (-3,5) and (6,-1).
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
= 5 -(-1) / -3-6
= 6/-9
= -2/3
(y - y1) = m(x - x1)
y -(-1) = -2/3(x - 6)
y + 1 = -2/3x + 4
y = -2/3x + 3
One week into the course, a 27-year-old student is added to Mr. McKee's section roster. How does this change affect the standard deviation of the set of student ages?
The standard deviation will stay the same as it is not affected by a change in a single measurement,
What is a standard deviation?
A standard deviation is a measure of how dispersed the data when compared to the mean.
In this case, the standard deviation will stay the same as it is not affected by a change in a single measurement. Therefore, the change will not affect the standard deviation of the set of student ages.

A. As the population of the beaver represents a certain law along with the year.
B. The point Q labels that 3.5 years after 1995 the amount of beaver has grown up to 475 approximately.
C. According to the question, the population is grown exponentially.
p(t) pass through point ( 1, 100), (2, 200), ( 3, 400), ( 4, 800)
therefore, 200 = 100 x 2 = 100 x 2 ^1 = 100 x 2^ 2-1
400 = 100 x 4 = 100 x 2 ^2 = 100 x 2^ 3-1
800 = 100 x 8 = 100 x 2 ^3 = 100 x 2^ 4-1
Answer = p (t) 100 . 2 ^ t-1

Answer:
The difference between a two step equation and a inequality equation is that two step equation you can isolate the variable and get the answer. However in a inequality equation you can only compare, for example A > 7
Step-by-step explanation:
A inequality compares not giving a clear answer. A two step equation lets you find a clear answer.
A cylinder has a height of 20 centimeters and a radius of 11 centimeters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer:
7598.8 [tex]cm^{2}[/tex]
Step-by-step explanation:
v (volume) = π[tex]r^{2}[/tex]h
v = 3.14 x [tex]11^{2}[/tex] x 20
v = 3.14 x 121 x 20
v = 7598.8
Answer:
7598.8 cm³
Step-by-step explanation:
Given :-
height = 20 cm
radius = 11 cm
value of π = 3.14
Formula to be used :-
Volume of cylinder = πr²h
Inputting the values :-
V = 3.14 x 11 x 11 x 20
= 3.14 x 121 x 20
= 3.14 x 2420
= 7598.8 cm³
For the following system a) What is the value of x? b ) What is the value of y ?
Answer:
x = 12
y = -23
Step-by-step explanation:
to solve for this i think we have to do:
y = -3x + 13
-
y = -2x + 1
-----------------------
0 = -x + 12
-x = -12
x = 12
then i think.... i think you have to substitute to one of the equations
y = -3(12) + 13
y = -36 + 13
y = -23
then to check we substitute to the second equation
-23 = -2(12) + 1 ?
-23 = -24 + 1?
-23 = -23

Can the side lengths of 7, 10, and 9 form a triangle?
========================================================
Explanation:
Add the first two sides to get 7+10 = 17 which is larger than the third side (9)Add the first and last sides to get 7+9 = 16 which is larger than the second side (10)Add the last two sides to get 10+9 = 19 which is larger than the first side (7)As that list above shows, adding any two sides results in a sum larger than the third remaining side. The conditions of the triangle inequality theorem have been met to allow for a triangle to be formed.
In general the triangle inequality theorem is:
a+b > ca+c > bb+c > aThe order doesn't matter. All that's important is that all three conditions are met.

The average conversion energy from producers to primary consumers will be 10%
What will be the energy transfer from producers to primary consumers?As we know that energy can not be created nor be destroyed but it can only be transferred from one form to another.
So the primary consumers take energy as food and this energy is utilized in their metabolism and the remaining they transfer.
The average conversion energy from producers to primary consumers is only 10%.
This percentage actually holds true for all transfer of energy at any trophic level in the food chain.
Majority of the energy loss can be attributed to metabolic processes that give off heat and other forms of energy.
