Answer:
Step-by-step explanation:
So, you have to isolate the variable. Think of it as finding how many plants she gave fertilizer to. 0.4n+8=25, when moving the 8 to the other side, it becomes negative. 0.4n=25-8. 0.4n=17. You then find the variable n. think of it as dividing 17 by 0.4 or multiplying n a certain number of times to find the number of plants.17/0.4 is 42.5. therefore, she gave 42 plants fertilizer, depending on what your teacher wanted to count. If she says round down, 42. If she wants to round up, 43. If she wants to be specific, 42.5. I would personally put the decimal.

On solving the inequality we get -6>5 which is not possible; hence there is NO SOLUTION possible for s.
We solve the given inequality for s as follows
2(4s-3) ≥ 5+8s
⇒8s - 6≥ 5 +8s
⇒ -6 > 5 (on subtracting 8s from both sides)
the last statement shows that variables cancel out from both sides of the inequality and we get -6>5 which is not possible. Because -6>5 is not possible or false, hence no value of s will be able to satisfy the given inequality. Thus the answer for s is NO SOLUTION.

4. Please find attached the graph of the number of wraps to the number of sandwiches
5. Please find attached the combined graph of the two functions
The similarity is the common slope
The difference is the y–intercept
What is the slope of a straight line graph?The slope is the ratio of the rise to the run of the graph.
The given function is; 2•x + 3•y = 1470
Where;
x = The number of sandwich sold
y = The number of wraps sold
The profit per sandwich sale = $2
Profit per each wrap sale = $3
1. The slope and intercept form is; y = m•x + c
Where;
m = The slope
c = The y–intercept
Therefore, 2•x + 3•y = 1470 gives;
3•y = 1470 - 2•x
y = (1470 - 2•x)÷3 = 490 - (2/3)•x
[tex] \displaystyle{y = \frac{1470-2\cdot x}{3} = 490 - \frac{2}{3} \cdot x}[/tex]
Therefore;
[tex] \displaystyle{y = 490 - \frac{2}{3} \cdot x}[/tex]By comparison, we have;
The slope, m = -2/3The y-intercept, c = 4902. Using the slope and intercept method to graph the line involves the following steps.
Mark the point (0, 490) on the graph to represent the y–interceptFrom the point (0, 490), move 2 units downwards and 3 units to the right to represent the slope of (-2/3) then mark a point at the location arrived at, which is (3, 488)Join the two points and extend the line to complete the graph3. The equation in function notation is; [tex] \displaystyle{f(x) = 490 - \frac{2}{3} \cdot x}[/tex]
The meaning of the function is that the number of wraps sold is given by the difference between 490 and two thirds of the number of sandwiches sold, or that as the number of sandwiches sold increases by by 1, the number of wraps sold decreases by 2/3

a machine can pack a 3 ft by 3 ft by 1 ft carton with packing material in 3 seconds. how long would it take to fill a carton that measures 4 ft by 4 ft by 6 ft?
a machine can pack a 3 ft by 3 ft by 1 ft carton with packing material in 3 seconds Then it would take 32 seconds to fill a carton that measures 4 ft by 4 ft by 6 ft
1) we calculate the volume of the first carton:
volume=length x width x height
volume=3 ft * 3 ft * 1 ft=9 ft³
Therefore:
A machine can fill 9 ft³ in 3 seconds.
2) we calculate the volume of the second carton.
volume=length x width x heigth
volume=4 ft * 4 ft * 6 ft=96 ft³
3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.
9 ft³---------------------3 seconds
96 ft³-------------------- x
x=(96 ft³ * 3 seconds) / 9 ft³=32 seconds.

They will together take 18 minutes to finish the sanitization work together.
It is mentioned that Liana can sanitize the guest room in 45 minutes only and Gab, her brother, can do the same in 30 minutes.
Let they take y minutes to finish the work together.
Let the total work be m
Workdone by Liana in 45 mintues = m
∴Workdone in 1 minute = m / 45
Workdone by Gab in 30 minutes = m
∴Workdone by Gab in 1 minute = m / 30
Let the total time taken by them = x minutes.
Total time taken by them together = m / 45 + m / 30

Graph this line using the slope
and y-intercept:
y= 1/6x + 4
Answer: See attached.
Step-by-step explanation:
To graph this, we will look at the pieces they gave us. Slope-intercept form equations are written in y = mx + b.
➜ The slope, m, is the pitch of the line. It's "rise over run" and helps us know where the plot points. For this problem, we will rise one value and move 6 values right to the next point.
➜ The y-intercept, b, is where the line intercepts the y-axis. It helps us know where the first point goes (0, y). For this problem, we will graph (0, 4).
Using these details, we will graph the line. View attached.

suppose f(x)=4x-2 and g(x)=-2x+1
find the value of f(3)/g(-4)
Answer:
10/9
Step-by-step explanation:
We can calculate f(3) and g(-4)
f(3) = 4*3 - 2 = 12 - 2 =10
and g(-4) = -2 * (-4) + 1 = 8 + 1 = 9
Then it is easy to calculate f(3)/g(-4):
f(3)/g(-4) = 10/9
where we use the values which we calculated before.
⇒In the equation f(x) given f(3) plug in the value 3 in the place of x and simplify
[tex]f(3)=4(3)-2\\f(3)=12-2\\F(3)=10[/tex]
⇒For g(-4) in the place of x plug in -4 in the equation of g

Find the missing angle.
Answer:
110 degrees?
Step-by-step explanation:
35+35= 70 right?
So then would have to subtract the 70 from 180 because that is total length of an angle to get 110 degrees
110 degrees
I might be wrong, because it might be different with triangles
Answer:
U = 110
Step-by-step explanation:
The formula for finding missing angle is.
a + b + c = 180 or in this case S + U + T = 180.
You already have the measurement of two angles so plug those in.
35 + U + 35 = 180
Now all you have to do is simplify and solve it.
35 + 35 + U = 180
70 + U = 180 you simplify by adding together 35.
U = 110 to cancel out 70 and isolate U you subtract 70 to both sides.
five fair dice were tossed, and the sum of the resulting tosses was recorded. this process was repeated 10,000 times using a computer simulation. the number of times the sum of the five tosses equaled 26 was 53. what is the estimated probability that the sum of the five dice will be 26? (give the answer to four decimal places.)
The estimated probability that the sum of five dice will be 26 is 0.0053
What is meant by Estimated Probability?Estimated Probability: Estimated probability is an approximation, or estimate, of theoretical probability. The larger the number of trials, the more accurate we expect this approximation to be. If E consists of a single outcome s, we refer to P(E) as the probability of the outcome s, and write P(s) for P(E)
N = Number of Repeated Process = 10,000
n = Number of times the sum of the five tosses equaled 26 = 53
The estimated probability that the sum of the five dice will be 26 = n/N
Where n = 53
And N = 10,000
Using the above formula, we have the following:-
n/N becomes
n/N = 53/10,000
n/N = 0.0053
Hence, the estimated probability that the sum of five dice will be 26 is 0.0053

find the edge length of a cube whose volume is 1.728cubic cm is the edge length a rational number
The edge lengths of a cube that has a 1.728 cm³ volume is 1.2 cm
What is the volume of a cube?The volume of a cube is the given by the length of one edge raised to the power of 3
The volume of a cube, V = Length, L × Width, W × Height, H
Given that the lengths of the edges of a cube are equal, we have!
Length, L = Width, W = Height, H
Which gives;
The volume of a cube, V = L × L × L = L³
Therefore, for the given cube, we have;
L³ = 1.728 cm³
1.728 = 1728/1000
(a + b)³ = a³ + 3•a²•b + 3•a•b² + b³
Taking a = 10, and b = 3, we have;
(10 + 2)³ = 10³ + 3×10²×2 + 3×10×2² + 2³ = 1728
Therefore;
1728/1000 = (10 + 2)³/10³ = 12³/10³
