Answers
Data:
• 180 pears are needed for 225 cups
Procedure:
To get the number of pears needed for one cup we have to divide the number of pears given by the number of cups given.
\(\frac{180}{225}=\frac{4}{5}=0.8\)You could have done the same with the second number of pears and cups given (160 and 200, respectively), getting the same result.

What percent larger is 20.49 trillion to 13.4 trillion
Answers
The answer of the given question based on the percent is , 20.49 trillion is about 52.84% larger than 13.4 trillion.
What is Percentage?Percentage is a way of expressing a quantity or value as a fraction of 100. It is a widely used method for describing proportions, rates, changes, and comparisons in various fields such as mathematics, economics, statistics, science, and everyday life. The term "percent" literally means "per hundred", and it is represented by the symbol "%". To convert a number to a percentage, we multiply it by 100 and add the symbol "%".
To find the percent larger that 20.49 trillion is to 13.4 trillion, we can use the following formula:
Percent change = (New value -Old value) /Old value * 100%
Plugging in the values we have:
Percent change = (20.49 trillion - 13.4 trillion) / 13.4 trillion * 100%
= 7.09 trillion / 13.4 trillion * 100%
= 52.84%
Therefore, 20.49 trillion is about 52.84% larger than 13.4 trillion.

Given the points P (3, 5) and Q (-5, 7) on the cartesian plane such that R (x, y) is
the midpoint of PQ, find the equation of the line that passes through R and
perpendicular
to PQ.
Answers
Answer:
-22=22
Step-by-step explanation:
3,5-5,7=
-22/22
The equation of the line passing through R and PQ is 4(y - 6) = -x - 1/2.
To find the equation of the line passing through the midpoint R and the points P and Q, we first need to find the coordinates of the midpoint R. The midpoint coordinates can be found by taking the average of the x-coordinates and the average of the y-coordinates of P and Q.
The x-coordinate of the midpoint R is (3 + (-5)) / 2 = -1/2.
The y-coordinate of the midpoint R is (5 + 7) / 2 = 6.
So, the coordinates of the midpoint R are (-1/2, 6).
Next, we can use the two-point form of the equation of a line, which states that the equation of the line passing through points (x₁, y₁) and (x₂, y₂) is given by:
(y - y₁) = (y₂ - y₁) / (x₂ - x₁) \(\times\) (x - x₁)
Substituting the coordinates of R (-1/2, 6) and P (3, 5) into the equation, we have:
(y - 6) = (7 - 5) / (-5 - 3) \(\times\)(x - (-1/2))
Simplifying the equation:
(y - 6) = (2 / -8) \(\times\)(x + 1/2)
(y - 6) = -1/4 \(\times\)(x + 1/2)
4(y - 6) = -x - 1/2
Therefore, the equation of the line passing through R and PQ is 4(y - 6) = -x - 1/2.

Answers
The possible probabilities for events A and B are P(A) =0.20 and P(B) = 0.05 where the values satisfied P(A and B) = P(A) × P(B).
Events A and B are independent.
P(A and B) = 0.25
we need to find possible probabilities for events A and B.
What is probability?Probability refers to the occurrence of a random event. The probability of an event is always is between 0 and 1.
The probability for two independent events P(A) and P(B) is
P(A and B) = P(A) × P(B)
if P(A and B) = 0.25
Solving by putting the option one by one, we get
For P(A)=0.5 and P(B)=0.5, P(A and B) ≠ P(A) × P(B)
For P(A)=0.25 and P(B)=0.25, P(A and B) ≠ P(A) × P(B)
For, P(A) =0.20 and P(B) = 0.05,
P(A) × P(B) = 0.25 which is equal to P(A and B).
So, the possible probabilities for events A and B are P(A) =0.20 and P(B) = 0.05 where the values satisfied P(A and B) = P(A) × P(B).

SH . Given f(x)=x²-3x and g(x)=2x-5, find each value. a. f(-4) b. g(1)-f(-3) c. f(g(-4))
Answers
a. To find f(-4), we simply substitute -4 for x in the function f(x):
f(-4) = (-4)² - 3(-4) = 16 + 12 = 28
Therefore, f(-4) = 28.
b. To find g(1)-f(-3), we first need to find g(1) and f(-3) separately.
g(1) = 2(1) - 5 = -3
f(-3) = (-3)² - 3(-3) = 9 + 9 = 18
Then, we can substitute these values into the expression:
g(1)-f(-3) = -3 - 18 = -21
Therefore, g(1)-f(-3) = -21.
c. To find f(g(-4)), we first need to find g(-4) and then substitute this value into f(x).
g(-4) = 2(-4) - 5 = -8 - 5 = -13
Then, we can substitute -13 for x in the function f(x):
f(g(-4)) = (-13)² - 3(-13) = 169 + 39 = 208
Therefore, f(g(-4)) = 208.
