The length of a rectangle is 1 more than twice the width. The area of the rectangle is given by the formula A = l × w. Which of the following equations could be used to find the area?
A)
A = 2w2 + w
B)
A = w2 + 2w
C)
A = 2w2
D)
A = 3w
The area of the rectangle will be given as Area = 2W² + W. Then the correct option is A.
What is a rectangle?It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
The length of a rectangle is 1 more than twice the width.
The area of the rectangle is given by the formula A = L x W.
Then the area of the rectangle will be
The relation between the length and width is given below.
L = 2W + 1
Then the area will be
Area = L x W
Area = (2W + 1)W
Area = 2W² + W

(75 hundredths) + (4 x 100) + (67 ones) + (5 tens) 2. Rocky's rug is in the shape of a rectangle. The width of the rug is 2 feet. The length of the rug is 4 feet. Enter the area, in square feet, of Rocky's rug.
Answer:
[tex]A=8\ feet^2[/tex]
Step-by-step explanation:
Given that,
The width of the rug is 2 feet.
The length of the rug is 4 feet.
We need to find the area of the rug. Fo a rectangle shape, the area of the rectangle is given by :
A = lb
So,
[tex]A=2\times 4\\\\A=8\ feet^2[/tex]
So, the area of the rug is [tex]8\ feet^2[/tex].

A scientist is investigating whether percent concentration can be used to predict density in apple juice. A scientist selected a random sample of 12 apple juice varieties and recorded the density, in pounds per cubic inch, and the percent concentration of each apple juice variety. The scientist wants to estimate the mean change in the density, in pounds per cubic inch, for each increase of 1 percent concentration of apple juice. Assuming the conditions for inference have been met, which of the following inference procedures is most appropriate for this investigation?
a. A linear regression t-interval for slope.
b. A matched-pairs t-interval for a mean difference.
c. A two-sample t-interval for a difference between means.
d. A one-sample t-test for means.
e. A two-sample z-interval for a difference between proportions
Answer:
The most appropriate inference procedure for the investigation is;
a. A linear regression t-interval for the slope
Step-by-step explanation:
Given that the slope of an horizontal line is zero, we have that there is no change in the y (dependent) variable when there is a change in the x-variable, therefore, it is important to find the true relationship between the two variables, 'x', and 'y'
The confidence interval of the slope is calculated and analyzed to determine if it excludes or includes, 0, such that, if the confidence interval exclude 0, then, it is unlikely that the slope is 0, therefore, there the relationship between the variables, 'x', and 'y' is significant
Therefore, a linear regression t-interval for the slope is most appropriate.

Samir and Christian had a total of 360 marbles Samir lost 28 marbles while Christian brought 18 more marbles both of them had an equal number of marbles in the end how many marbles did Samir have at the beginning
Step-by-step explanation:
Marbles altogether = 360
Marbles Samir Lost = 28
360 - 28 = 332
Marbles Christian bought 18
332 + 18 = 350
Marbles both had in the end = 350 ÷ 2 = 175
Marbles Samir have at the beginning = 175 + 28 = 203
Answer = 203
1. The pollution level in the center of a city at 6 am is 30 parts per million and it
grows in linear fashion by 25 parts per million every hour. If y is pollution
and t is time elapsed after 6 am, determine:
a. The equation that relates y with t.
b. The pollution level at 4 o'clock in the afternoon
Answer:
a) [tex]y(t) = 30 + 25t[/tex]
b) The pollution level at 4 o'clock in the afternoon is of 280 parts per million.
Step-by-step explanation:
The pollution level in the center of a city at 6 am is 30 parts per million and it grows in linear fashion by 25 parts per million every hour.
This means that the pollution in t hours after 6 am is given by:
[tex]y(t) = 30 + 25t[/tex], which is the answer to question a.
b. The pollution level at 4 o'clock in the afternoon
4 in the afternoon is 10 hours after 6 am, so this is y(10).
[tex]y(10) = 30 + 25*10 = 30 + 250 = 280[/tex]
The pollution level at 4 o'clock in the afternoon is of 280 parts per million.

Answer:
49 units
Step-by-step explanation:
The units on the other 3 sides (this is excluding the slanted portion ofc.)
would add up to 36.
Now you only left with doing the slanted portion of the shape. We must use pythagorean theorem to solve for the slanted portion. The longer leg, 12 units long. Just count from the point (18,4) and then stop at (18,16) it stops on the same line as the point (13,16)
Leg B=12
Leg A=5
Leg C=?
[tex]a^2+b^2=c^2[/tex]
25+144=196
Then square root 169. You will get 13
36+13=49
Q4. Three students A, B and C had 3 soil samples. Each student poured 180 mL of water
into the soil samples they had. Time taken for the percolation of water through the three
soil samples was 25 min, 10 min and 40 min respectively. Which student had the soil with
the highest percolation rate?
Answer:
Student B
Step-by-step explanation:
Soil percolation is the porosity of soil to the downward flow of water through it. A soil with high percolation allows water to drain through it downwards in a less period of time.
From the given experiment by students, it takes 25 min for water to percolate through the soil sample of student A, 10 min for the soil sample of student B and 40 min for the soil sample of student C. Thus, the student that had the soil sample with highest percolation rate is B.

To compare two products such as colas, a random sample is selected to taste two types of colas (A and B). Each selected subject tastes both colas and selects his/her preferred cola. What sample size would be needed to ensure that the margin of error in the brand preference is less than 5 percentage points in more than 95% of experiments
Answer: The sample size would be needed = 385
Step-by-step explanation:
Let p be the prior population proportion.
Margin of error = E
When not estimate of p is given , the formula to calculate the minimum sample size n = [tex]0.25(\dfrac{z^*}{E})^2[/tex] , where z* = critical value for given confidence interval.
Here z* for 95% confidence level is 1.96.
E=5%=0.05
Then [tex]n=0.25(\dfrac{1.96}{0.05})^2\approx385[/tex]
Hence, the sample size would be needed = 385

2h=10$
3h=15$
4h=20$
5h=25$
So you can pay 35$ for the snow play ski park and then you can be there 5hours.So 35$ for the entry+25$ for the 5 hours=60$

What is the equation of the line that passes through the point (5, -6) and has a
slope of 3/5
Answer:
y = 3/5x + -9
or y = 3/5x - 9
Step-by-step explanation:
Since you are already given the slope for this equation all you have to do is plug in the ordered pair in this equation: y = mx+b
Here is what this equation stands for:
y = the y in the order pair you are given, in this case it would be -6
m = This is the slope, sometimes you may not be given the slope so you would have to find it, but in this case, you are given it, the slope is 3/5
x = the x in the ordered pair you are given, in this case it would be 5
b = This is the y-intercept, you will mostly be solving for this most of the time
(5,-6)
(x, y)
y = mx+b (Use this Formula)
-6 = 3/5(5) +b (The numbers have been substituted within the formula)
-6 = 3+b (simplify the equation by multiplying the slope by the x)
-6-3 = b ( once simplified the left side of the equation, go to the right side, but remember when you do that you have to change the sign because you are eliminating 3 on the left side completely, "what you do on one side, do it to the other side")
-9 = b (solve)
y = 3/5x + -9 (plug in the slope and B(y-intercept) within the formula - y = mx+b, make sure that you are not plugging in x and y for this step)
