Answer:
Step-by-step explanation:
Let's start by using the formula for the perimeter of a rectangle:
P = 2L + 2W
where P is the perimeter, L is the length, and W is the width.
We are given that the perimeter is 70 cm, so we can substitute this in the formula:
70 = 2L + 2W
Dividing both sides by 2, we get:
35 = L + W
We are also given that the length is six times the width, so we can write:
L = 6W
Substituting this in the equation we just derived, we get:
35 = 6W + W
Simplifying, we get:
35 = 7W
Dividing both sides by 7, we get:
W = 5
So the width of the rectangle is 5 cm.
Using the equation L = 6W, we can find the length:
L = 6 x 5 = 30
So the length of the rectangle is 30 cm.
Therefore, the length of the rectangle is 30 cm and the width is 5 cm.

The quantity of wheat, in billions of bushels, that wheat suppliers are willing to produce in a year and offer for sale is called the quantity supplied and is denoted by S. The quantity supplied is determined by the price P of wheat, in dollars per bushel, and the relation is
P = 2.13S − 0.65
.
The quantity of wheat, in billions of bushels, that wheat consumers are willing to purchase in a year is called the quantity demanded and is denoted by D. The quantity demanded is also determined by the price P of wheat, and the relation is
P = 2.55 − 0.55D
.
At the equilibrium price, the quantity supplied and the quantity demanded are the same. Find the equilibrium price for wheat. (Round your answer to two decimal places.)
Answer:
1.89billions
Step-by-step explanation:
Given
The quantity demanded determined by the price P of wheat, and the relation is
P = 2.55 − 0.55D
Also, the quantity supplied is determined by the price P of wheat, in dollars per bushel, and the relation is
P = 2.13S − 0.65
At equilibrium, the price of wheat will be the same i.e;
2.13S-0.65 = 2.55-0.55D
Also since at the equilibrium price, the quantity supplied and the quantity demanded are the same, then S = D
Substitute into the formula
2.13S-0.65 = 2.55-0.55S
2.13S+0.55S = 2.55+0.65
2.68S = 3.20
S = 3.20/2.68
S = 1.194
Get the equilibrium price of wheat;
Given;
P = 2.13S − 0.65
P = 2.13(1.194) − 0.65
P = 2.5433-0.65
P = 1.893
Hence the equilibrium price of wheat is approximately 1.89billions
Answer:
The equilibrium price for wheat is 3.663 dollars per bushel
Step-by-step explanation:
The quantity of wheat, in billions of bushels, that wheat suppliers are willing to produce in a year and offer for sale, determined by the price P of wheat, is:
P = 2.13*S - 0.65
On the other hand, you know that the amount of wheat, in billions of bushels, that wheat consumers are willing to buy in a year, determined by the price P of wheat, is:
P = 2.55 - 0.55*D
The market equilibrium or point of equilibrium is that point where there is an equilibrium because the demanders are willing to buy the same units that the suppliers want to manufacture, for the same price.
Being at the equilibrium price, the quantity supplied and the quantity demanded must be equal. So, being:
P = 2.13*S - 0.65 → P + 0.65=2.13*S → \(\frac{P+0.65}{2.13} =S\)P = 2.55 - 0.55*D → P+ 2.55= - 0.55*D → \(\frac{P+2.55}{-0.55} =D\)the quantity supplied S must be equal to the quantity demanded D:
S=D
\(\frac{P+0.65}{2.13} =\frac{P+2.55}{-0.55}\)
Solving:
\((-0.55)*\frac{P+0.65}{2.13} =P+2.55\)
\(\frac{-0.55}{2.13} *(P+0.65) =P+2.55\)
\(-\frac{55}{213} *(P+0.65) =P+2.55\)
\(-\frac{55}{213} *P-0.168 =P+2.55\)
\(-\frac{55}{213} *P-P =2.55+0.168\)
\(0.742*P =2.718\)
P=2.718÷0.742
P=3.663
The equilibrium price for wheat is 3.663 dollars per bushel
A set of (x,y) paired data values yields the following results: the x values have a sample mean of 12, the y values have a sample mean of 38, the y values have a sample standard deviation of 4, the x values have a sample standard deviation of 3, and the correlation coefficient between x and y is .76. Compute the least squares regression line for the data, and then predict what the y value should be if x is 4.
Answer:
Least square regression:
y = 1.0136x + 25.8404
Value of y if x is 4:
y = 29.8936
Step-by-step explanation:
Given:
x' = 12
y' = 38
\( \sigma y = 4 \)
\( \sigma x = 3 \)
coefficient between x and y, r = 0.76
Take the least square regression as:
y - y' = byx (x - x')
Let's find byx:
\( byx = r (\frac{\sigma y}{\sigma x}) \)
\(byx = 0.76 (\frac{4}{3}) = 1.0133\)
We'll now compute the least squares regression line for the data, and then predict what the y value should be if x is 4.
Take the regression equation:
y - y' = byx (x - x')
Substitute figures:
y - 38 = 1.0133 (x - 12)
Expand the equation:
y - 38 = 1.0133x - 12.1596
y = 1.0133x - 12.1596 + 38
y = 1.0136x + 25.8404
The y value when x= 4:
y - 38 = 1.0133(4) + 25.8404
y - 38 = 4.0532 + 25.8404
y = 29.8936
Therefore,
Least square regression:
y = 1.0136x + 25.8404
Value of y if x is 4:
y = 29.8936

The sum of the geometric series for Xac-2 n\((n ~ 1) (~1)" I2"-2 for Ixl < 1 is (1 - x2)\). This is because the series is a summation of the terms (1/x2) multiplied by each power of x from 0 to n, and the sum of the series is the sum of the terms.
To calculate the sum of the geometric series for\(Xac-2 n (n ~ 1) (~1)" I2"-2 for Ixl < 1\), we can use the formula for the sum of a geometric series. The sum of such a series is the sum of the terms (1/x2) multiplied by each power of x from 0 to n. Thus, the sum of the series is given by the formula S = (1/x2) ∑ xn, where n starts at 0 and goes to n. Substituting n = -2 and x = 1 gives us S = (1/1) ∑ 1-2, which simplifies to S = (1/1) (1 - 1-2) = (1 - 1-2) = (1 - x2). Hence, the sum of the series is (1 - x2).

the ratio of collectible pennants kyle owns to pennants that yasmine owns is 3:2 yasmine has 36 pennants . How will the ratio of kyles pennants to yasmines pennants change if they both sell half of their pennants Explain
Answer:
If they both sell half then Kyle would have 1.5:1 and Yasmine would have 18 pennants.
Step-by-step explanation:
It will change because if they both sell half, they would have to multiply by .05 or divide by 2 because that is half of something.
3/2 or 3*0.5 = 1.5
2/2 or 2*0.5 = 1
36/2 or 36*0.5 = 18
So Kyle would have 1.5:1 pennants left and Yasmine would have 18 pennants left.

Step-by-step explanation:
Subtract -4x on both sides to get to -2y=-4x-8, then you should divide -2 into both sides to get to the slope of y=2x+4 since two negatives would equal to a positive when dividing and multiplying. Because the slope is positive, it is safe to assume that the first two options A and B are the best options due to their slopes being positive and going up. The y-intercept is 4 which makes the answer A because on 0 it is on the positive side.

Describe Angles?In geometry, an angle is a measure of the amount of rotation between two intersecting lines or line segments. It is typically measured in degrees or radians. Angles are important concepts in geometry as they help us to understand and describe the relationships between different geometric figures.
An angle is formed by two rays or line segments that share a common endpoint called the vertex of the angle. The rays or line segments are referred to as the sides of the angle. The size of an angle is determined by the amount of rotation between the two sides, measured in degrees or radians.
Vertical opposite angles are congruent, which means that:
6x - 6 = 9x - 48
Simplifying this equation, we get:
3x = 42
Dividing both sides by 3, we get:
x = 14
Now we can use the value of x to find the measure of the adjacent angle z:
z = 180 - (6x - 6 + 9x - 48)
Simplifying and substituting x = 14, we get:
z = 180 - (6(14) - 6 + 9(14) - 48)
z = 180 - (84 - 6 + 126 - 48)
z = 180 - 168
z = 12°
Therefore, the values of x and z are x = 14 and z = 12° , respectively.

Since the vertical opposite angles are equal, we can set them equal to each other and solve for x:
6x - 6 = 9x - 48
Subtracting 6x from both sides, we get:
-6 = 3x - 48
Adding 48 to both sides, we get:
42 = 3x
Dividing by 3, we get:
x = 14
Now, we can find the value of angle z:
angle z + (6x - 6) = 180 [Linear pair]
Substituting x = 14, we get:
angle z + 78 = 180
Simplifying, we get:
angle z = 180 - 78
angle z = 102°

In mathematics, the logarithmic function is defined as inverse function to exponent function and defined as f(x) = logₐx where a is base of function. Properties of Logarithmic Functions :
Product Rule : logₐ MN = logₐ M + logₐ N , with the same base, multiply two numbers result add the exponents.Quotient Rule : logₐ M/N = logₐ M – logₐ N, with the same base, divide two numbers result add the exponents.Power Rule : Raise an exponential expression to power and multiply the exponents. Logₐ Mᵖ = p logₐ MZero Exponent Rule, logₐ 1 = 0.We have, a natural logarithmic function, i.e., base = 10, f(x) = ln (1/gᵏ) and we have to expand it. To expand logarithms means write them as a sum or difference product of logarithms. The order to apply rules is quotient rule, product rule and then power rule. So, f(x) = ln (1/gᵏ)
applying quotient rule,

Appling power rule,
=> f(x) = ln(1) - k ln( g)
Applying Zero Exponent Rule,
