If the length of a rectangle doubles its width. Find the length of the rectangle if the perimeter is 21cm
Answer:
7cm, assuming the question is phrased as noted below.
Step-by-step explanation:
I'll interpret "If the length of a rectangle doubles its width." as "If the length of a rectangle is double its width.
Let L be the width, and L the length
L = 2W
The perimeter of a rectangle is 2L + 2W
We can use L instead of 2W, and that gives us:
21 cm = 2L + L
21 cm = 3L
L = 7 cm
Subtract -5x^2-9x+8 from −6x ^2+5
A researcher plans to use a random sample of houses to estimate the mean size (in square feet) of the houses in a large population. The researcher is deciding between a 95% confidence level and a 99% confidence level. Compared with a 95% confidence interval, a 99% confidence interval will be
Considering the margin of error, it is found that the 99% confidence interval will be wider than the 95% confidence interval.
What is the margin of error of a confidence interval?It is given by:
[tex]M = z\frac{s}{\sqrt{n}}[/tex]
In which:
z is the critical value, which increases with a higher confidence level.s is the standard deviation.n is the sample size.From this, we get that the margin of error is direct proportional to the critical value, hence [tex]z_{99}>z_{95}[/tex], which means that the 99% confidence interval will be wider, that is, it will have a larger margin of error, than the 95% confidence interval.

1 8. DIG DEEPER! You have 1/8 gallon of melted crayon wax. You pour the wax equally into 8 different molds to make new crayons. What fraction of a cup of melted wax is in each mold? Think: 1 gallon is 16 cups.
Each mold will have 1/32 cup of melted wax.
What is Fraction?A fraction represents a part of a whole.
We know that 1 gallon is equal to 16 cups.
Therefore, 1/8 gallon is equal to:
(1/8) x 16 cups/gallon = 2 cups/8 = 1/4 cup
So we have 1/4 cup of melted crayon wax in total.
If we pour this equally into 8 different molds to make new crayons, each mold will have:
(1/4) / 8 = 1/4 x 1/8 = 1/32 cup
Therefore, each mold will have 1/32 cup of melted wax.

Step-by-step explanation:
k = 2
The point (0, 0) on the graph of f(x) tells you f (0) = 0.
The point (-4, 0) on the graph of g(x) tells you g (-2) = 0.
Now we know that
g(-2) = 0 = f(0) = f(-2+k)

0 = -2+k
2 = k
The value of k is 2

The equation −16x2 + 10x + 15 = 0 represents the height, in feet, of a flotation device above the water after x seconds. The linear term represents the initial velocity. The constant term represents the initial height.
a. If the initial velocity is 0, when should the flotation device land in the water?
b. If the initial height is 0, when does the flotation device land in the wate
Answer:
a) 0.968 s (nearest thousandth)
b) 0.625 s
Step-by-step explanation:
Give equation: [tex]-16x^2 + 10x + 15 = 0[/tex]
If the linear term represents the initial velocity,
then the initial velocity in the original equation = 10 ft/s
If the constant term represents the initial height,
then the initial height in the original equation = 15 ft
a) If the initial velocity is 0
[tex]\implies -16x^2 + 15 = 0[/tex]
[tex]\implies x^2 = \dfrac{15}{16}[/tex]
[tex]\implies x = \pm\dfrac{\sqrt{15}}{4}[/tex]
As time is positive,
[tex]\implies x =\dfrac{\sqrt{15}}{4}=0.9682458366...[/tex]
The flotation device will hit the water after 0.968 s (nearest thousandth)
b) If the initial height is 0:
[tex]\implies -16x^2 + 10x = 0[/tex]
[tex]\implies -2x(8x-5) = 0[/tex]
[tex]\implies -2x=0\implies x=0[/tex]
[tex]\implies 8x-5=0 \implies x=\dfrac58[/tex]
Therefore, the flotation device lands in the water after 5/8 seconds = 0.625 s

A company manufactures and sells video games. A survey of video game stores indicated that at a price of $88 each, the demand
would be 200 games, and at a price of $38 each, the demand would be 1,200 games. If a linear relationship between price and
demand exists, which of the following equations models the price-demand relationship?
(Let x represent the price per video game and y represent the demand.)
A
y = 20x- 1,560
В.
y = 20x
C.
y = -20x + 1,960
D.
y = -20x + 1,560
The price-demand relationship of the company is a linear model
The equation that models the price-demand relationship is y = -20x + 1960
How to determine the linear relationship?From the question, we have the following points:
(x, y) = (88, 200) and (38, 1200)
The equation of the linear relationship is then calculated as:
[tex]y = \frac{y_2 - y_1}{x_2 -x_1} * (x - x_1) + y_1[/tex]
Substitute known values in the above equation
[tex]y = \frac{1200 - 200}{38 -88} * (x - 88) + 200[/tex]
Evaluate the difference
[tex]y = \frac{1000}{-50} * (x - 88) + 200[/tex]
Evaluate the quotient
[tex]y = -20 * (x - 88) + 200[/tex]
Expand
[tex]y = -20x + 1760 + 200[/tex]
Evaluate the sum
[tex]y = -20x + 1960[/tex]
Hence, the equation that models the price-demand relationship is y = -20x + 1960

The perimeter of a reclangle is 44 meters. Its width is 10 meters. What is the length of the rectangle
A.10 meters
B.12 meters
C.14 meters
D.34 meters
Answer: B
The answer would have to be B because when finding the perimeter, you add all the sides up together. If one of the width of the rectangle is 10, then the other would also be 10, which already makes 20. If both lengths are 12, they would add up to be 24. And finally, 20+24=44!
