A philanthropist decided to donate 46% of her savings to charity.
What fraction of the philanthropist's savings was donated?
Answers
The fraction of the philanthropist's savings donated = 23/50
The percentage of the savings that the philanthropist wants to donate = 46%
Percentages can be converted to fractions by dividing by 100 and reducing the resulting fraction to the lowest term.
The reduction to the lowest term is done by dividing both the numerator and denominator by the same value
The fraction of the philanthropist's savings donated = 46/100
Reduce the fraction to the lowest term by dividing the numerator and denominator by 2
The reduced fraction becomes
\( \frac{46 \:\div2}{100 \:\div2} \)
The fraction of the philanthropist's savings donated = 23/50

What is Velocity?Velocity is defined as the rate of change of distance of a body with respect to time
We can use the relationship between linear velocity and angular velocity for gears to solve this problem:
v = rω
where v is the linear velocity, r is the radius of the gear, and ω is the angular velocity.
We are given the linear velocity of the larger gear, which is 17π/6 inches per second.
v = 17π/6 inches per second
ω = (34π/3) / 60 radians per second
the radius of the smaller gear is:
r = v / ω
= (17π/6) / ((34π/3) / 60)
= 17π/6×60/(34π/3)
=17π/6×60×3/34π
= 1/6 ×60× 3/2
= 180/12
=15 feet
Hence, the radius of the smaller gear is 15 feet.

"if f(x) / (x - 2) = x ^ 3 + 2x - 4 + 13/(x - 2) what is f(2)"
and
"if f(x) / (x + 3) = 3x ^ 2 - 4x + 2 what is f(-3)"
Answers
The denominator is zero (0/0 is undefined), we cannot determine the exact value of f(-3) using this equation.
To solve the given equations, we need to find the value of the function f(x) for specific values of x.
"If f(x) / (x - 2) = x³ + 2x - 4 + 13/(x - 2), what is f(2)?"
To find f(2), we can substitute x = 2 into the equation and solve for f(2).
Plugging in x = 2, we get:
f(2) / (2 - 2) = 2³ + 2(2) - 4 + 13/(2 - 2)
Since the denominator is zero (2 - 2 = 0), the equation is undefined. Therefore, there is no solution for f(2) in this case.
"If f(x) / (x + 3) = 3x² - 4x + 2, what is f(-3)?"
To find f(-3), we can substitute x = -3 into the equation and solve for f(-3).
Plugging in x = -3, we get:
f(-3) / (-3 + 3) = 3(-3)² - 4(-3) + 2
Simplifying, we have:
f(-3) / 0 = 3(9) + 12 + 2
f(-3) / 0 = 27 + 12 + 2
f(-3) / 0 = 41
Additional information or context is needed to solve for f(-3).

What are angles?Two lines intersect at a location, creating an angle.
An "angle" is the term used to describe the width of the "opening" between these two rays. The character is used to represent it.
Angles are frequently expressed in degrees and radians, a unit of circularity or rotation.
In geometry, an angle is created by joining two rays at their ends. These rays are referred to as the angle's sides or arms.
An angle has two primary components: the arms and the vertex.
the two rays' shared vertex serves as their common terminal.

3 6 9 12 15 18 21 24 27 30 is odd or even numbers?
Answers
Answer: Half of them are even and half of them are odd.
Step-by-step explanation:
The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.
The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.
Therefore, out of the given numbers, half of them are even and half of them are odd.

African Safari While on a safari in Africa I saw a small herd of zebras and cranes wandering over the grassland. I counted 18 heads in all and counted 60 legs. How many zebras were there and how many cranes
Answers
Answer:
6 Cranes
Step-by-step explanation:
Given
Animals: Zebra & Cranes
\(Heads = 18\)
\(Legs = 60\)
Required
Determine the number of Cranes
Represent Zebra with Z and Cranes with C
A Zebra has 1 head and 4 legs
A Crane has 1 head and 2 legs
So:
\(Z + C = 18\)
\(4Z + 2C = 60\)
Make Z the subject in the first equation
\(Z = 18 - C\)
Substitute 18 - C for Z in the second
\(4(18 - C) + 2C = 60\)
\(72 - 4C + 2C = 60\)
Collect Like Terms
\(- 4C + 2C = 60 - 72\)
\(- 2C = -12\)
\(2C = 12\)

If f(x) = x²- 6x + 2 and g(x) = -2x, find the following composition.

Answers
The composition (g o f)(5) has a value of 6
How to evaluate the composite function?The definitions of the functions are given as
f(x) = x²- 6x + 2 and g(x) = -2x
To find the composition (g o f)(5), we make use of
(g o f)(x) = g(f(x))
So, we have the following equation
(g o f)(x) = -2f(x)
Substitute f(x) = x²- 6x + 2 in (g o f)(x) = -2f(x)
So, we have
(g o f)(x) = -2 x (x²- 6x + 2 )
Substitute 5 for x
So, we have the following equation
(g o f)(5) = -2 x (5²- 6 x 5 + 2)
Evaluate the expression
So, we have the following equation
(g o f)(5) = 6
Hence, the value of the composition is 6

Apply the Laws of Exponents to write an equivalent expression for the given expression.
(-9-4)7
(-9-4)² =
(Simplify your answer. Type your answer using exponential notation.)
Answers
Answer:
169
Step-by-step explanation:
To apply the Laws of Exponents and write an equivalent expression for (-9-4)², we need to simplify the expression step by step.
First, let's simplify the expression (-9-4)²:
(-9-4)² = (-13)²
Next, we apply the exponent rule for a negative base. According to the rule, when a negative number is raised to an even exponent, the result is positive. So, we have:
(-13)² = 13²
Now, we can simplify 13² using the exponent rule for multiplication:
13² = 13 * 13 = 169
Therefore, the equivalent expression for (-9-4)² is 169.

__ __ __ __
| | | | |

Each batch uses 3/2 cups of blueberries
B) To find the number of batches Lin can make, we need to divide the total amount of blueberries by the amount of blueberries per batch:
4 cups of blueberries ÷ (3/2 cups of blueberries per batch)
= (4 cups of blueberries) × (2/3 batches per cup of blueberries)
= 8/3 batches
Therefore, Lin can make 8/3 or approximately 2.67 batches of blueberry muffins using all of the blueberries.
C) To find the fraction of a batch Lin will need to make in order to use all of the blueberries, we need to subtract the number of whole batches from the total number of batches:
8/3 batches - 2 batches = 2/3 of a batch
Therefore, Lin will need to make 2/3 of a batch in order to use all of the blueberries.

Find the probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees. Would this outcome warrant a replacement cup (meaning that it would be unusual)
Answers
Answer: The probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees =0.042
This outcome would warrant a replacement cup.
Step-by-step explanation:
Let x be a random variable that represents the temperature of hot chocolates.
GIven: Mean temperature = 175 degrees
standard deviation = 8.1 degrees
The probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees =\(P(x<161)\)
\(=P(\dfrac{x-\mu}{\sigma}<\dfrac{161-175}{8.1})\\\\=P(Z<-1.7284) [Z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(Z<1.7284)\\\\=1-0.9580\\\\=0.042\)
Hence, the probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees =0.042 < 0.5 (unusual)
i.e. this outcome would warrant a replacement cup.
