Answer:
Hey there!
A total of 250-175, or 75 liters of water evaporated.
75/250=0.3, or 30%
30% of water evaporated.
Hope this helps :)
Hey there! I'm happy to help!
First, let's find out how much water evaporated. We have 175 left of the 250 after evaporation, so we need to subtract 175 from 250 to see how much water evaporated.
250-175=75
75 liters evaporated. Now, we want to find this as a percent out of 250. 75 is what percent of 250? Well, when talking about percents, the word "is" means "equals". So, we can turn this into an equation! We will use x to represent our percent as a decimal.
75= x·250
We simply divide both sides by 250 to isolate the x, giving us x=0.3
0.3 is 30% as a percent, so this means that 30% of the water evaporated.
I hope that this helps! Have a wonderful day!
which set of steps will translate f(x)=6x to g(x)=6x-5-7
THIS IS THE COMPLETE QUESTION BELOW;
Which set of steps will translate f(x) = 6x to g(x) = 6x – 5 – 7?
Shift f(x) = 6x five units to the left and seven units up.
Shift f(x) = 6x five units to the right and seven units down.
Shift f(x) = 6x seven units to the right and five units up.
Shift f(x) = 6x seven units to the left and five units down.
Answer:
Shift f(x)=6x five units to the left and seven units down.
Step-by-step explanation:
We are told to translate the function below
f(x) = 6x to g(x) = 6x – 5 – 7
Which means the process to translate f(x) into g(x) is required.
According to the translation rule
f(x)-------->f(x)+a
If a<0 it shift to downward
If a>0 it shift to upward
Then we have
(X,y) ----->((x - 5, y)
There is a shift by x coordinates towards left by 5 units
then we would have the function as
f'(x) = 6(x-5)
Following the translation rule there is a shift by the function by 7 units downward direction then we have
(x,y) ----->(x,y -7)
Then we have g(x) = 6x – 5 – 7 as our translation product.
Therefore, shift f(x)=6x five units to the left and seven units down.

A shopkeeper sold an article at 20 % discount and made a loss of Rs 90. If he had
sold it at 5 % discount, he would have gained Rs 90. Find the cost price and the
marked price of the article.
Answer:
The cost price of the article is Rs 1050
The marked price of the article Rs 1200
Step-by-step explanation:
The given discount on the article = 20%
The amount loss = Rs 90
With a discount of 5% the amount gained = Rs 90
Let the cost price of the article = X
Let the marked price of the article = Y
Therefore, we have;
(1 - 0.2) × Y = X - Rs 90
(1 - 0.5) × Y = X + Rs 90
Which gives;
0.8·Y = X - Rs 90 .......................(1)
0.95·Y = X + Rs 90.....................(2)
Subtracting equation (1) from equation (2), we have;
0.95·Y-0.8·Y = X + Rs 90 - (X - Rs 90) = X - X + Rs 90 + Rs 90 = Rs 180
0.15·Y = Rs 180
Y = Rs 180/0.15 = Rs 1200
Therefor, the marked price of the article = Rs 1200
From;
0.8·Y = X - Rs 90, we have;
0.8×Rs 1200 = X - Rs 90
X = 0.8× 1200 + 90 = Rs 1050
Therefore, the cost price of the article = Rs 1050.

Which of the following best describes the relationship between (x-3) and the
polynomial x2 + 4x2 + 2?
A. It is impossible to tell whether (x-3) is a factor.
B. (x-3) is a factor
C. (x-3) is not a factor.
Answer:
C
Step-by-step explanation:
If (x - 3) is a factor of the polynomial then evaluating the polynomial for x = 3 should give a result of zero, that is
3² + 4(3)² + 2 = 9 + 36 + 2 = 47 ≠ 0
Thus (x - 3) is not a factor → C

Determine what type of model best fits the given situation:
A model rocket fired straight up from the ground, where h is the height of the rocket and t is the time in seconds.
Answer:
Ok, i will suppose the situation that:
The rocket has a constant speed S (So the acceleration of the rocket is equal in magnitude, but opposite in direction, to the gravitational acceleration)
Here we can remember that:
Velocity = distance/time.
Then if the distance is the height of the rocket, we can write this as:
H = velocity*time
h = S*t
This is a linear model that represents the height of the rocket as a function of time.
Case 2:
The rocket is fired with an initial velocity v0, but no acceleration:
In this case the only acceleration acting on the rocket is the gravitatonal acceleration pulling the rocket down, so the acceleration is:
a = -g
To get the velocity as a function of time, we should integrate:
a = -g*t + v0
To get the height as a function of time, we integrate again:
h(t) = (-g/2)*t^2 + v0*t + p0
Where p0 is the initial position of te rocket, but the rocket starts at the ground, so p0 = 0m.
The height as a function of time is:
h(t) = (-g/2)*t^2 + v0*t
This is a quadratic equation.

Gwen participates in an online rewards program.She earns points for completing surveys. Gwen earns 10 points for each survey she completes,and she wants to predict the total number of points that she will earn based on the number of surveys that she completes. Which quantities in this situation have more than one possible value? Choose All That apply.
The number of surveys Gwen completes.
The number of points Gwen earns for completing each survey.
The total number of points Gwen earns.
Answer:
Step-by-step explanation:
Hello,
For each survey that Gwen completes she earns 10 points.
So the number of points Gwen earns for completing each survey is 10 and there is only one value.
If x is the number of surveys Gwen completed, her number of points is 10 multiplied by x.
The number of surveys Gwen completes can have several values.
And then, the total number of points Gwen earns can have several values too.
So you need to choose
The number of surveys Gwen completes.
and
The total number of points Gwen earns.
Hope this helps.

Jennifer wants to see if the color of the testing room causes test anxiety. She asks 100 participants to come to a modified classroom, and as they walk in, she asks each person to choose either a testing cubicle painted bright red or a testing cubicle painted off white. On the basis of their choices, participants spend 20 minutes in one or the other cubicle solving challenging math problems. Then, they complete a survey asking them questions about how anxious they were during the math test. What's wrong with Jennifer's experiment?
Answer: Jennifer didn't randomly assign participants to the control and experimental group.
Step-by-step explanation: In the scenario discussed above, Jennifer failed to perform a random assignment of the participants who took part in the survey, that is the experimental group, those who receive the treatment and the control group, those who don't. Random assignment is required in other to address the issue of bias in our experiment. She was supposed to perform a random assignment of the participants to the two groups instead of asking them to make a choice.

Hint: Sum = (n-2)180
Enter
Answer:
x = 125°
Step-by-step explanation:
The given polygon is a hexagon with 6 sides.
The sum of the interior angles for any given polygon = (n - 2)180, where n is the number of sides of the polygon.
Therefore:
[tex] x + 117 + 124 + 102 + 145 + 107 = (6 - 2)180 [/tex]
[tex] x + 595 = (4)180 [/tex]
[tex] x + 595 = 720 [/tex]
Subtract both sides by 595 to solve for x:
[tex] x + 595 - 595 = 720 - 595 [/tex]
[tex] x = 125 [/tex]
x = 125°

TW = 3.2 yd
Step-by-step explanation:
In the picture attached,
Triangle TWV has been given with angle W = 90°
By applying Sine rule in the given right triangle,
Since, Sine of an angle is the ratio of its opposite side and hypotenuse (side opposite to the right angle)
SinV = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
SinV = [tex]\frac{\text{TW}}{\text{TV}}[/tex]
Sin(32)°= [tex]\frac{\text{TW}}{6}[/tex]
TW = 6.Sin(32)°
TW = 3.1795
TW = 3.2 yd
Therefore, measure of the side TW = 3.2 yd.
Solve sin 20 = COS CE-30)
Answer:
CE = 100°
