Answer:
35% of 60 = 21
the answer is 21
this is how you set it up
x/60=35/100
you first multiply 35 and 60 and your answer should be 2100 then you divide 2100 by 100 and that equals 21

(30 POINTS COME AND GET IT FOR A MULTIPLE CHOUCE XD) which of the following is the solution for s in the system of equation shown below? R+2s=52
2r-s=4
(1)12
(2)15
(3)17
(4)20
Answer:
(4) s = 20Step-by-step explanation:
Given system:
r + 2s = 522r - s = 4Eliminate r to solve for s.
To do so, double the first equation and then subtract the second one:
2r + 4s = 1042r - s = 4Subtract
4s - (-s) = 104 - 45s = 100s = 100/5s = 20Correct choice is (4) 20

A lake near the Arctic Circle is covered by a 3 meter thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After four weeks, she is only 1.6 m thick. Pls hurry!
Complete question :
A lake near the Arctic Circle is covered by a 3 meter thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After four weeks, she is only 1.6 m thick. Let S(t) denote the ice sheet's thickness S (measured in meters) as a function of time t (measured in weeks). Write the function's formula
Answer:
S(t) = 3 - 0.3t
Step-by-step explanation:
Given that:
Initial thickness = 3m
Assume the rate of decrease is constant
Thickness after 4 weeks = 1.6 m
To obtain a function for the scenario described above :
We can observe that the function is a linear function, given that rate of decrease per week is constant :
To obtain the rate of decrease :
Change after 4 weeks :
(Initial thickness - thickness after 4 weeks) / number of weeks
(3m - 1.6m) / 4
= 1.2m / 4
= 0.3 m per week
General form of a linear function :
y = mx + c
m = rate of change per unit
Hence, our function becomes ;
S(t) = 3 - 0.3t
There is a line that includes the points (9,1) and has a slope of 1/3. What is the equation in slope-intercept form?
Answer:
f(x) = 1/3x + 1
Step-by-step explanation:
slope-intercept form is
f(x) = mx + b
so just put the points in and you have:
f(x) = 1/3x + 1
also b stands for the y-intercept so if you look at your point (9,1) than your y-intercept would be 1.

You lose 2 points every time you forget to write your name on a test. You have forgotten to write your name 4 times. What integer represents your change in points from forgetting to write your name?
Answer:
-8
Step-by-step explanation: since it says Times, (for me times is multiplication) you would multiply -2 and 4. negative 2 would be from that person losing 2 points. and 4 since it is your total amount of times you have forgotten to write your name. so, -2 x 4 = -8.
how i got -8. both signs from -2 and 4 are different, and when they are different the answer will always be negative.
describes the end behavior of the graph.
Answer:
+ ∞
Step-by-step explanation:
If you look at the graph you can see that the arrow is pointing upward, indicating that the graph continues in that direction forever. Also, the question is asking, as you move the right (or as x increases) what happens to y. y is increasing infinitely in end behavior.
What is the equation of the line that has a slope of 1/2 and passes through the point (6,4)? Write your answer in slope intercept form
Answer:
A
Step-by-step explanation:took it on edge!
Answer:
y = 1/2x + 1
Step-by-step explanation:
slope-intercept form: y = mx + b
If you have a slope of 1/2, m = 1/2
y = 1/2x + b
To find b, plug in the known point.
4 = 1/2(6) + b
Solve.
4 = 3 + b
b = 1
Plug b into your equation.
y = 1/2x + 1
(3) Explain how you can tell that the point (5, 13) is a solution to the system shown
without formally solving the system.
y = 4x - 7
2x + y = 23
The point (5, 13) is a solution to the system
The system of equations is given as:
[tex]y = 4x - 7[/tex]
[tex]2x + y = 23[/tex]
The solution is given as: (5,13)
To determine if the coordinate point is a solution of the system of equations, we have to substitute the x and y values in the equations.
So, we have:
[tex]y = 4x - 7[/tex]
[tex]13 = 4 \times 5 - 7[/tex]
[tex]13 = 13[/tex]
[tex]2x + y = 23[/tex]
[tex]2 \times 5 + 13 = 23[/tex]
[tex]10+ 13 = 23[/tex]
[tex]23 = 23[/tex]
The above equations are true.
Hence, the point (5, 13) is a solution to the system
