Answer:
l = (S - πr²) / π
Step-by-step explanation:
The problem gives us the formula for the surface area of a cone S, we will solve the formula for l.
The formula is
S = πl + πr²
If we take the πr² to the other side, we get:
S - πr² = πl
Now we divide by π, and we get:
(S - πr²) / π = l
Therefore solving for l, we get that
l = (S - πr²) / π.

Kiko is coasting on her bicycle down a hill. After 3 s, her speed is 10 m/s. After 8 s, her speed is 25 m/s. What is her acceleration during this time?
Kiko is coasting on her bicycle down a hill. After 3 s, her speed is 10 m/s. After 8 s, her speed is 25 m/s. Her acceleration during this time will be 5 m/s².
What is acceleration?Acceleration is the rate of change in both speed and direction of velocity over time. When anything moves faster or slower in a straight line, it is said to have been accelerated. Because the direction is always shifting, motion on a circle accelerates even while the speed is constant.
It is given that, Kiko is coasting on her bicycle down a hill. After 3 s, her speed is 10 m/s. After 8 s, her speed is 25 m/s.
Acceleration is found as the ratio of the change in speed to the change in a time interval.
Acceleration = change in speed/ change in a time interval
Acceleration = (25-10) / (8-5)
Acceleration = (15)/(3)
Acceleration = 5 m/s²
Thus, Kiko is coasting on her bicycle down a hill. After 3 s, her speed is 10 m/s. After 8 s, her speed is 25 m/s. Her acceleration during this time will be 5 m/s².

Hogan needs to rent a car while on vacation. The cost of the vehicle is $21 per day. He gives the office manager $180 up front. If x represents the number of days and y represents the total cost of the rental, which equation will help Hogan determine if he owes the agency money at the end of his trip or if the agency owes him money?
Answer:
[tex]y=21x-180[/tex]
Step-by-step explanation:
The cost of the vehicle is $21 per day. He gives the office manager $180 up front.
The upfront is a type of advance payment that is deducted from the final amount.
Let x represents the number of days and y represents the total cost of the rental.
So, the correct equation here is :
[tex]y=21x-180[/tex]
Your cruise ship is leaving for a 610 league adventure. how many nautical miles is this
Final answer:
A 610-league adventure is equivalent to 1830 nautical miles, calculated by multiplying the number of leagues by the conversion factor, where one league is equal to approximately 3 nautical miles.
Explanation:
To convert the distance from leagues to nautical miles, we need to know the conversion factor. One league is approximately 3 nautical miles. Thus, by multiplying the given number of leagues by this factor, we can determine the distance in nautical miles.
If the cruise ship is embarking on a 610-league adventure, we calculate the equivalent distance in nautical miles as follows:
Multiply the number of leagues (610) by the conversion factor (3).
The calculation would be 610 leagues * 3 nautical miles/league = 1830 nautical miles.
Therefore, a 610-league voyage is equivalent to 1830 nautical miles.
Find the remainder when f(x) is divided by (x - k).
f(x) = 4x3 - 5x2 + 2x + 11; k= 3
Answer:
The remainder is 80
Step-by-step explanation:
Given the polynomial
[tex]f(x)=4x^3-5x^2+2x+11[/tex]
we have to find the remainder when the above polynomial f(x) is divided by x-3
By remainder theorem when we put x=3 in f(x) we get the remainder i.e f(3)
[tex]f(3)=4(3)^3-5(3)^2+2(3)+11[/tex]
[tex]=108-45+6+11[/tex]
[tex]=80[/tex]
which is required remainder.
Hence, the remainder is 80

The gross income of Abelina Bennett is $215 per week. Her deductions are: $15.16, FICA tax; $29.33, income tax; 2% state tax; 1% city tax; and 3% retirement fund. What is her net income?
To calculate Abelina Bennett's net income, subtract her deductions from her gross income. Her net income is $157.61 per week.
Explanation:To calculate Abelina Bennett's net income, we need to subtract her deductions from her gross income. The deductions include FICA tax, income tax, state tax, city tax, and retirement fund.
Step 1: Add up all the deductions:
FICA tax: $15.16
Income tax: $29.33
State tax: 2% of $215 = $4.30
City tax: 1% of $215 = $2.15
Retirement fund: 3% of $215 = $6.45
Step 2: Calculate the total deductions: $15.16 + $29.33 + $4.30 + $2.15 + $6.45 = $57.39
Step 3: Subtract the total deductions from the gross income: $215 - $57.39 = $157.61
Abelina Bennett's net income is $157.61 per week.
If there are 400 people in a room, what is the probability of at least 2 people sharing the same birthday?
The probability of at least 2 people out of 400 sharing the same birthday is almost certain due to the 'birthday paradox', due to there being only 365 days in the year but 400 people in the room.
Explanation:The probability that at least 2 people out of 400 sharing the same birthday is almost certain due to the 'birthday paradox.' This is because there are only 365 days in a year for birthdays, but we have 400 people in the room.
To calculate this probability, we assume that every person is equally likely to be born on any day of the year (ignoring leap years). The first person can have their birthday on any of 365 days. The second person has a 364/365 chance of not having the same birthday as the first. The third person has a 363/365 chance of not sharing a birthday with the first two, and so on. By the time we reach the 366th person, the probability of them not sharing a birthday with anyone else is zero, since all 365 possible birthdays have been taken.
So, the overall probability of at least 2 people sharing a birthday is 1 minus the probability of all 400 people having unique birthdays. When you calculate it with 400 people, the result is almost 1, which indicates that it's nearly certain at least 2 people share a birthday.

A digital camera memory card is 1/4 full. The card is 2/3 full when 375 more pictures have been taken. How many pictures can the memory card hold?
Final answer:
The memory card can hold a total of 900 pictures.
Explanation:
The question asks us to find the total capacity of the memory card in a digital camera by using the information that it is 1/4 full before 375 pictures are added, and 2/3 full after these pictures are added.
Let's define the total capacity of the memory card as 'x' pictures.
If 1/4 of the card is full, then it contains x/4 pictures.
After adding 375 pictures, the card becomes 2/3 full, which means:
x/4 + 375 = (2/3)x
To solve for x, we need to get all the x's on one side of the equation and the numbers on the other side:
Multiply both sides of the equation by 12 to get rid of the fractions: 12(x/4) + 12(375) = 12(2/3)xSimplify the equation: 3x + 4500 = 8xSubtract 3x from both sides: 4500 = 5xDivide both sides by 5: 900 = xTherefore, the memory card can hold a total of 900 pictures.
Identify the property that justifies the following statement: if 16m=160,then m=10
Division Property of Equality
16m = 160
divide both sides by 16 to find m
m = 160/16 = 10
Answer:
Property of equality for division.Step-by-step explanation:
The given expression is
[tex]16m=160[/tex]
So, we use one of the properties of equalities for division, which states that if we divide one side of the equation, we also must divide the other side by the same number, to not mess up the balance of the equation. Applying this property, we have
[tex]\frac{16m}{16}=\frac{160}{16}\\ m=10[/tex]
