The area of each small square is 16 square centimeters. What is the side length of the window? Explain
Answers
Answer:
Length=4 cm
Step-by-step explanation:
Solve for L
L*W=A
16 cm^2=L*W
Since this a square. W will equal L.
So [tex]\sqrt{16} =4[/tex]
Meaning that the length is 4
The area of a square is given by:
Area = Side²
If the area of a square is 16 square centimeters, the side length of the window is 4 cm.
What is a square?A square is a four-sided polygon, whose all sides are equal in length and whose opposite sides are parallel to each other.
We have,
Area of the square = 16 square centimeters
The area of a square is given as:
Area = side²
Area = 16 cm²
16 cm² = side²
Square root on both sides
[ 4² = 16 ]
√16 cm² = √side²
Side = 4 cm
Thus if the area of the square is 16 square centimeters, the side length of the window is 4 cm.

Since +P looks to be 7, -P would be -7
Hope this helps :)
Answer:
-7
Step-by-step explanation:
P is a variable, and P can only have 1 value. Thanks to the number line, we know what this value is. P is positive 7. If we know that the set value of P is positive 7, then we can just treat it like it is positive 7.
P - 5 = 2
P + 3 = 10
So putting a negative sign in front of P will mean it will be

An elevator travels down from the top floor of a skyscraper. The graph below represents its height, in feet, over time in seconds. What does the slope of the line represent?
Answers
Answer:
So Y, which represents height, goes down depending on how far you are in time, which is X.
The slope of the graph represents the elevator's descent speed, calculated as 12 feet per second based on the points (1, 838) and (2, 826).
The Slope of the line in the graph represents the rate of change of height with respect to time, or the speed of the elevator's descent.
In this case, the slope can be calculated using the formula: slope = (change in height) / (change in time). We know that the elevator's height changes from 838 feet at 1 second to 826 feet at 2 seconds,
So, the change in height is : 838 - 826 = 12 feet, and the change in time is 2 - 1 = 1 second.
Therefore, the slope is 12 feet/second, this indicates that the elevator is descending at a speed of 12 feet per second.

What are the endpoints of the major axis and minor axis of the ellipse? ((x - 2) ^ 2)/36 + ((y + 3) ^ 2)/24 = 1 Drag coordinates into the boxes to correctly complete the table
Answers
From the equation of the elipse, we have that:
The endpoints of the major axis are: [tex]x = -4[/tex] and [tex]x = 8[/tex]The endpoints of the minor axis are: [tex]y = -3 - \sqrt{24}[/tex] and [tex]y = -3 + \sqrt{24}[/tex].The equation of an elipse of center [tex](x_0,y_0)[/tex] has the following format:
[tex]\frac{(x - x_0)^2}{a^2} + \frac{(y - y_0)^2}{b^2} = 1[/tex]
If a > b, we have that:
The endpoints of the major axis are: [tex]x = x_0 \pm a[/tex]The endpoints of the minor axis are: [tex]y = y_0 \pm b[/tex]In this problem, the equation is:
[tex]\frac{(x - 2)^2}{36} + \frac{(y + 3)^2}{24} = 1[/tex]
Thus [tex]x_0 = 2, y_0 = -3, a = 6, b = \sqrt{24}[/tex]
For the major axis:
[tex]x = x_0 \pm a[/tex]
[tex]x = 2 \pm 6[/tex]
[tex]x = 2 - 6 = -4[/tex]
[tex]x = 2 + 6 = 8[/tex]
The endpoints of the major axis are: [tex]x = -4[/tex] and [tex]x = 8[/tex]
For the minor axis:
[tex]y = y_0 \pm b[/tex]
[tex]y = -3 \pm \sqrt{24}[/tex]
[tex]y = -3 - \sqrt{24}[/tex]
[tex]y = -3 + \sqrt{24}[/tex]
The endpoints of the minor axis are: [tex]y = -3 - \sqrt{24}[/tex] and [tex]y = -3 + \sqrt{24}[/tex].

1) The equation 2y + 3x = 12 in the y = mx + b form is [tex]y = -\frac{2}{3} x + 4[/tex]
2) The linear equation y = -2x - 1 in the Ax + By = C form is 2x + y = -1
The point-slope form of the equation of a line is y = mx + b
where m represents the slope
b represents the y-intercept
The given equation is:
2x + 3y = 12 (Given)
Subtract 2x from both sides
2x + (-2x) + 3y = 12 + (-2x)
3y = 12 - 2x (Equality property of addition)
3y = -2x + 12 (Commutative property of addition)
Divide both sides by 3
[tex]\frac{3y}{3} = -\frac{2}{3} x + \frac{12}{3} \\\\y = -\frac{2}{3} x + 4[/tex](Equality property of division)
2) Write the linear y = -2x - 1 into Ax + By = C
y = -2x - 1 (Given)
Add 2x to both sides
y + 2x = -2x + 2x - 1 (Equality property of addition)
y + 2x = -1
2x + y = -1 (Commutative property of addition)

Maggie makes some fruit punch. She mixes 2 1/2 quarts of grape juice with 1 1/2 quarts of orange juice. One quart of grape juice costs $1 less than one quart of orange juice. She finds that the total of making the fruit punch is $12.50. Calculate the cost of each quart of grape juice and each quart of orange juice.
Answers
G = O - 1
Orange juice and Grape juice is 12.50 total.
O+G=12.50
or
O+O-1=12.50 since G=O-1
Solve
2O-1=12.50
2O=13.50
o=6.75
The cost is 6.75$ per quart of orange juice
Grape is just 1$ less than that. So 6.75-1 = 5.75. Grape juice costs 5.75 per quart.
We have 2 and 1/2 quarts of grape juice and 1 and 1/2 quarts of orange juice. Or 5/2 and 3/2 to make it easier.
Multiply the amount of quarts with the costs per quart.
5/2*5.75= 14.375
3/2*6.75=10.125
Total costs is
14.375+10.125=$24.5
The answer is it costs about $10.13 for orange and $14.38 for grape.

See attachment for illustration of the perpendicular lines l and m.
Figure 1 represents the original lineFigure 2 represents the line rotated 180 degreesFigure 3 represents the line reflected over line mUsing the attachment as a guide, we can see that both transformations do not have the same effect on the points on both lines.

First, notice that (a + 1/a)2 = 42 = 16. But also, (a + 1/a)2 = a2 + 2a(1/a) + 1/a2 = a2 + 2 + 1/a2 = a2 + 1/a2 + 2
So a2 + 1/a2 + 2 = 16, so a2 + 1/a2 = 14.
Now, do that again...
(a2 + 1/a2)2 = 142 = 196, but also (a2 + 1/a2)2 = a4 + 2(a2)(1/a2) + 1/a4 = a4 + 2 + 1/a4 = a4 + 1/a4 + 2
So a4 + 1/a4 + 2 = 196, so a4 + 1/a4 = 194
You can see the pattern... E.g., a8 + 1/a8 = 1942 - 2, etc.

The manager of the commercial mortgage department of a large bank has collected data during the past two years concerning the number of commercial mortgages approved per week. The results from these two years (104 weeks) are shown to the right.
Answers
The expected number of mortgages approved per week and the standard deviation of the distribution are 2.019 and 0.024 respectively.
The expected number of mortgages approved per week :
Mean = (Σfx ÷ Σf)Expected Number approved = 210 ÷ 104 = 2.019
Hence, it is expected that 2.019 mortageahes would be approved per week.
The standard deviation :
Variance = [Σ(Xi - x)² ÷ Σf] Standard deviation = √VarianceVariance = (59.5414 ÷ 104) = 0.0005698
Standard deviation = √0.0005698
Standard deviation = 0.024
Therefore, the expected value and standard deviation are 2.019 and 0.024 respectively.
