suppose that wendy rides her bicycle 30 miles in the same time it takes kim to ride her bicycle in 20 miles. if wendy rides 5 miles faster per hour than kim, find each rate.
Therefore , the solution of the given problem of speed comes out to be
K travels at a speed of 10 mph and W =15mph.
Speed: What is it?The speed seen from a distance tells us how fast something is moving. An object's speed determines how far it travels in a predetermined amount of time. Velocity is determined as velocity = distance * time. Meters / sec (m/s), kilometres per hourly (km/h), and kilometers / second (mph) are the three units of speed that are most frequently used (mph).
Here,
Let's say Wendy completes a 30-mile bicycle ride in the same amount of time that Kim completes a 20-mile ride.
Find the speed of each if Wendy bikes 5 mph faster than Kim.
When s Equals K's speed, (s+5) becomes W's speed.
They inform us that the 2 and half are equivalent, thus we can use this information to create a straightforward time equation: Time = Speed/Distance
K's time equals W's time, therefore
=> 20/s= 30/(s+5).
=>30s = 20(s+5)
=>30s = 20s + 100
=>30s - 20s = 100
=>10s = 100
=> s = 10
K travels at a speed of 10 mph, while W travels at 15 mph.

Julie bookwalter is single, claims 1 dependent and earns 32,300 annually the state tax rate is 2.5. What is the amount of exemptions and annual state income tax
The amount of exemption on annual state 2.5% is 807.5.
What are amount of exemptions ?
Income liable to income tax is decreased by an exemption. The Internal Revenue Service permits many different exemptions (IRS). Personal and dependent exemptions used to be the two most popular forms. However, the personal exemption has been eliminated through the end of 2025 as a result of the changes made by the 2017 Tax Cuts and Jobs Act (TCJA).
There are still additional types of exemptions besides dependent ones.
Step by step Explaination:
Julie earns 32,300 annually.
she pays State tax rate 2.5%
So, first we should calculate tax rat for 1%
32300*1%
=32300/100
=323.
For state tax rate 2.5%
32300*2.5%
=32300*2.5/100
=807.5
Exemption amount on 2.5% is 807.5.

The range of the function for the given domain is the one in option D.
{0, 6, 12, 18, 24}
How to find the range?Here we want to find the range of the function:
f(x) = 12 - 3x
For the domain {-4, -2, 0, 2, 4}
To find the range, we just need to evaluate the function f(x) on all the values of the domain, we will get:
f(-4) = 12 - 3*(-4) = 24
f(-2) = 12 - 3*-2 = 18
f(0) = 12 -3*0 = 12
f(2) = 12 - 3*2 = 6
f(4) = 12 - 3*4 = 0
So the range is just the set of these values {0, 6, 12, 18, 24}

Step-by-step explanation:
∠3 + ∠4 = 90° as shown with the square marking on the other side.
∠3 + 35° = 90°, 90°- 35° = ∠3
∠3 = 55°
∠1 = 90°, ∠3 = 55°, ∠2 = ?
A triangle's interior angles always add up to 180°.

there are 15 jolly ranchers in a jar containing three blue three red three green through yellow and three purple three jolly ranchers are chosen at random from the jar what is the probability that all three chosen jolly ranchers are blue
The probability of the event that all three are blue is 1/455 or 0.0022
What is Probability of an EventIn probability theory, the probability of an event is a measure of the likelihood that the event will occur. It is a value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event can be expressed as a decimal, a fraction, or a percentage.
Probability is used to quantify the uncertainty associated with a random event. It is based on the idea that if an experiment is repeated many times under the same conditions, the proportion of times the event of interest occurs will be close to the probability of that event.
The probability of an event can be calculated using the following formula:
Probability of an event = Number of favorable outcomes / Total number of possible outcomes
In this problem, we can define our variables.
Total number of possible outcomes = 15
P(All three are blue) = (3/15) * (2/14) * (1/13)
P(All three are blue) = 1/455
P(all three are blue) = 0.0022

70mi/hr?
b. If you are traveling 80 mi/hr on the freeway, explain if you are traveling at a
significantly high speed. Why?
The probability that a car selected at chance is moving at more than 70mi/hr is 0.02
What does "normal" describe in statistics?Normal usually refers to the word "normal" in a normal distribution.
The word normal is used when something occurs that has occurred frequently. The normal distribution is somewhat similar where the main observation (mean or its surrounding) occurs frequently and as we go far from the mean, its chances decrease.
Since the speeds of cars are normally distributed, is expressed as
z = (x - µ)/σ
Where x = speeds of cars
µ = mean speed
σ = standard deviation
From the information given,
µ = 60 mi/hr
σ = 5 mi/hr
P(x < 70 )
For x = 70
z = (70 - 60)/5 = 2

A bicyclist, initially at rest, begins pedaling and gaining speed steadily for 4.70s during which she covers 31.0m.
What was her final speed?
Answer: The final speed of the bicyclist is 6.60m/s.
Step-by-step explanation:
To find the final speed of the bicyclist, we need to use the formula:
Speed = Distance / Time
We know that the distance covered by the bicyclist is 31.0m and the time taken to cover that distance is 4.70s. So, we can substitute these values into the formula:
Speed = 31.0m / 4.70s
Solving this equation, we get:
Speed = 6.60m/s
So, the final speed of the bicyclist is 6.60m/s.

Rewrite the expression 4^ [-2] x 8^ [0] x 5 ^[6} using only positive exponents.
The expression 4^[-2] × 8^[0] × 5^[6] can be written with positive exponents as follows 4^[2] × 8^[0] × 5^[6].
What are exponents?Exponent is the term used to describe a way to represent huge numbers using powers. In other words, the exponent describes how many times a number has been multiplied by itself. Law of Multiples: Exponents should be added while maintaining the same base when multiplying similar bases.
When bases are raised by a power of two or more, multiply the exponents while maintaining the original base.
Division Rule: When dividing like bases, take the exponent of the denominator and divide it by the exponent of the numerator, keeping the base constant.
The expression 4^[-2] × 8^[0] × 5^[6] can be written with positive exponents as follows:
4^[2] × 8^[0] × 5^[6]
The negative sign in the value 2 can be ignored because squaring a number yields a positive value irrespective of the sign of the value.

Books were on sale for 20% off of the original price. Walter bought a book on sale that had an original price of $25.50.The sales tax was 6.5%.How much did walter pay for the book
The total amount of money Walter paid for the book after the removal of discount and addition of sales tax is $21.726
What amount did Walter paid for the book?Percentage discount = 20%
Original price = $25.50
Sales tax = 6.5%
New price after discount = $25.50 - (20% × $25.50)
= 25.50 - (5.1)
= $20.4
Actual amount paid with sales tax = $20.4 + (6.5% × $20.4)

Tickets to enter a museum were R30 for each child and R60 for each adult. In a particular day 100 adults brought
3 children each and the remaining adults brought 2 children each. Children alone were not allowed to enter the
museum. The total tickets sales from the children and adults was R25800. How many children and adults entered the
museum?
A) 270
B) 470
C) 670
D) None of these
Answer:
D
Step-by-step explanation:
Let's say the number of adults who brought 3 children each is x. So the number of adults who brought 2 children each is 100-x.
Then the total number of children is 3x + 2(100-x) = 300 + x.
The total amount of money made from adults is 60 * 100 = 6000.
The total amount of money made from children is 30 * (300 + x) = 9000 + 30x.
So 6000 + 9000 + 30x = 25800
=> 15000 + 30x = 25800
=> 15000 = 25800 - 30x
=> 15000 = 25800 - 30x
=> 30x = 10800
=> x = 360
So the number of adults who brought 3 children each is 360 and the number of adults who brought 2 children each is 100-360 = -260 (which is not possible).
So the answer is D) None of these.
To solve the problem, set up equations using the given information. Substitute the value of one variable into the other equation to solve for both variables. Then use the values to find the number of children and adults.
Explanation:To solve this problem, we can start by setting up equations based on the given information. Let's denote the number of adults as A and the number of children as C. We know that each adult brought either 3 children or 2 children, resulting in a total ticket sales of R25800.
So we can set up the following equation: 30C + 60A = 25800.
We also know that there were 100 adults. If each adult brought 3 children, then the total number of children would be 3 times the number of adults: C = 3A.
Substituting the value of C from the second equation into the first equation, we get 30(3A) + 60A = 25800. Solving this equation will give us the values of A and C.
