they receive 25 per entry but 5 goes towards the cost of the race
so 25-5 = 20 per entry is for the charity
so 20x + 5000 = 25000
subtract 5000 from each side
20x= 20000
divide both sides by 20
x = 20000/ 20
x = 1000
they need at least 1000 entries to make 25000
so to make more than 25000, they need 1001 entries

Solve each problem and write your answer in scientific notation. (6.0x10^5)x(3.0x10^4)
The simplified form of the given expression is [tex]1.8\times10^{10}[/tex].
The given expression is [tex](6.0\times10^5)\times(3.0\times10^4)[/tex].
We need to solve the given expression and write the answer in scientific notation.
What is a scientific notation?The scientific notation helps us to represent the numbers that are very huge or very tiny in a form of multiplication of single-digit numbers and 10 raised to the power of the respective exponent. The exponent is positive if the number is very large and it is negative if the number is very small.
Now, [tex](6.0\times10^5)\times(3.0\times10^4)=18\times10^5\times10^4[/tex]
[tex]=18\times10^{5+4}[/tex]
[tex]=18\times10^9[/tex]
[tex]=1.8\times10^{10}[/tex]
Therefore, the simplified form of the given expression is [tex]1.8\times10^{10}[/tex].

What is the area of a rectangle with vertices at (−3, −1) , (1, 3) , (3, 1) , and (−1, −3) ? Enter your answer in the box. Do not round any side lengths. ___units²
The area of the rectangle is 8 units².
Explanation:To find the area of a rectangle, we can use the formula A = length * width. In this case, we can use the coordinates of the vertices to determine the length and width of the rectangle.
Using the distance formula, we can find the length between the points (-3, -1) and (1, 3) to be 4 units, and the width between the points (1, 3) and (3, 1) to be 2 units.
Therefore, the area of the rectangle is 4 * 2 = 8 units².

There is a sales tax of $6 on an item that costs $93 before tax. A second item costs $294.50 before tax. What is the sales tax on the second item?
Answer:
its 19
Step-by-step explanation:
If a second item costs $294.50 before tax. The sales tax on the second item will be $19.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, there is a sales tax of $6 on an item that costs $93 before tax. A second item costs $294.50 before tax.
We have to apply the ratio as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
$6/$93 = t/$294.5
t = 6 × 294.5 / 93
t = $ 19
Thus, if a second item costs $294.50 before tax. The sales tax on the second item will be $19.

Name a pair of adjacent complementary angles
In geometry, complementary angles are two angles whose measures add up to 90 degrees. A pair of adjacent complementary angles could be 30 degrees and 60 degrees.
Explanation:In geometry, complementary angles are two angles whose measures add up to 90 degrees. For example, if one angle measures 30 degrees, the other angle measures 60 degrees because 30 + 60 = 90. So, a pair of adjacent complementary angles could be 30 degrees and 60 degrees.

A car travels 416 miles in 8 hours and at this rate how many miles will the car travel in 22 hours
To find out how many miles the car will travel in 22 hours, we calculate the unit rate by dividing 416 miles by 8 hours to get 52 miles per hour and then multiply this unit rate by 22 hours to get 1144 miles
The question involves calculating the distance a car will travel at a given rate over a different period of time. This is a basic rate problem in math, often approached by finding the unit rate and then scaling it to the desired time.
Step 1: Identify the rate of travel. The car travels 416 miles in 8 hours.
Step 2: Find the unit rate by dividing the distance by the time. Unit rate = 416 miles / 8 hours = 52 miles per hour.
Step 3: Calculate the distance the car will travel in 22 hours using the unit rate. Distance = 52 miles/hour * 22 hours = 1144 miles.
So, at this rate, the car will travel 1144 miles in 22 hours
To buy a truck you can pay $14,000 cash or put down $5000 and make 24 monthly payments of $551.09. how much would you save by paying cash (to the nearest hundredth)?
Final answer:
By paying $14,000 in cash for the truck instead of making a $5,000 down payment and 24 monthly payments of $551.09, you would save $4,226.16.
Explanation:
To determine how much you would save by paying cash for the truck versus making a down payment and monthly payments, we need to calculate the total cost for each option.
Down payment: $5,000
Monthly payments: 24 payments of $551.09 each
The total cost when financing the truck would be:
$$5,000 + (24 × $551.09) = $5,000 + $13,226.16 = $18,226.16$
The cash payment option is $14,000. Therefore, the savings when paying cash would be:
$$18,226.16 - $14,000 = $4,226.16$
By paying cash, you would save $4,226.16, to the nearest hundredth.

The pitch of the roof is the number of feet the roof rises for each 12 feet horizontally. If a roof has a pitch of 8. What is its slope expressed as a positive number? What does the slope mean in this story?
The slope of the roof, expressed as a positive number, is 0.67. This represents the steepness of a roof, with a higher number indicating a steeper roof. The figure is calculated using the rise over run ratio.
Explanation:The pitch of a roof is a number that expresses how much the roof's height changes for every 12 feet you move along horizontally. If a roof has a pitch of 8, it means that for every 12 feet you move horizontally, the height of the roof increases by 8 feet. This gives us a rise/run ratio, which is how slope is defined in mathematical terms.
In this case, the rise is 8 feet, and the run is 12 feet. So, the slope would be 8/12, or 0.67 when expressed as a positive decimal number.
The slope here represents the steepness of the roof. A higher slope means a steeper roof and vice versa. By expressing the slope as a number, we can get an idea of how steep the roof is without having to see it in person.

Consider the function represented by the graph. What is the domain of this function
Answer: The answer is [tex]\{x:x\geq 0\}.[/tex]
Step-by-step explanation: We are given a graph that represents a function. We are to find the domain of the graphed function.
Domain and Range: If y=f(x) is a function, then the domain is the set of all first elements of ordered pairs (x-coordinates) and the range is the set of all second elements of ordered pairs (y-coordinates).
In the given graph, 'x' takes the values from 0 to infinity and 'y' takes the values from negative infinity to 9.
Therefore, domain of the function is [0, ∞) and the range is (-∞, 9).
Thus, the domain is given by the set [tex]\{x:x\geq 0\}.[/tex]
