Answer:
E. 1 nickel
Step-by-step explanation:
2 ten cent= 20 cent
a quarter is 25 cent
25-20=5
a nickel is 5 cent
Answer:
E.) nickle (5 cents)
Step-by-step explanation:
You give 25 cents (value of a quarter)
2 ten-cent candies is equal to 20 cents:
[tex]2*10=20\\10+10=20[/tex]
Find the difference between what you paid and the actual amount:
[tex]25-20=5[/tex]
You paid an extra 5 cents. Find the answer that has the same value as 5 cents:
A. ) 1 dime
This is wrong because a dime is worth 10 cents, not 5
B.) 1 nickel 2 pennies
this is wrong because a nickle is worth 5 cents and a penny is worthy 1 cent. Add the values, and the change would be 7 cents.
C.) 2 dimes
This is wrong because a dime is worth 10 cents, so 2 dimes would be 20 cents.
D.) 2 nickles
This is wrong because a nickle is worth 5 cents, so 2 nickles would be 10 cents.
E.) 1 nickle
This is correct because a nickle is worth 5 cents, the exact change you should receive.

A blanket is 4 feet wide. It is 3 times as long as it is wide. Find the perimeter and area of the blanket.
Answer:
P: 32
A: 48
Step-by-step explanation:
(4+(4*3))*2=32
4*(4*3)=48
The blanket is 4 feet wide and 12 feet long. The perimeter of the blanket is 32 feet and the area is 48 square feet.
Explanation:The blanket is given to be 4 feet wide, and its length is 3 times its width, which means the length is 3 x 4 = 12 feet. Therefore, the blanket is 4 feet wide and 12 feet long.
For a rectangle, the formula for perimeter is 2*(length + width). Plugging in our values gives us 2*(12 + 4) = 32 feet.
The formula for the area of a rectangle is length * width. Using our dimensions, the area is 12 * 4 = 48 square feet.

Your credit card limit is $5,000, and your current balance is $4,500. Your credit score will increase by 10 points for every $250 decrease in your balance. At the end of the year you have paid down your balance to $2,500. By how many points has your credit score increased?
Answer:
80
Step-by-step explanation:
4500-2500 is 2000 dollars reduction, or money paid off.
For every 250 dollars, there is a 10 points increase. 2000 divided by 250 is 8. There are 8 sets of 250 dollars. So, for every 250 dollars (you have 8 of them), 10 points increase. Therefore, you multiply 10 by 8.
10x8 = 80. Your credit score has increased by 80 points.
At the end of the year, my credit score would have increased by 80 points.
If my current balance is $4500 and at the end of the year, my balance is $2500. It means that the total decrease in my credit balance is $2000 ($4500 - $2500).
In order to determine the total increase in the number of points, the first step is to determine the amount of 250 that is in 2000. In order to do this, the first step would be to divide 2000 by 250.
2000 / 250 = 8
The second step is to multiply 8 by 10
8 x 10 = 80 points.

Your water bill lists a previous reading of 5,520 ccf and a present reading of 5,981 ccf. The water company charges $0.93 per ccf of water. How much will you be charged on the current bill?
Answer:
$428.73
Step-by-step explanation:
The previous reading of the water bill is 5,520 ccf and a present reading of 5,981 ccf.
The number of units used is given as the present reading minus the previous reading.
This means that the number of units used is:
5981 - 5520 = 461 ccf
The water company charges $0.93 per ccf of water.
Therefore, the charges on the current bill will be:
0.93 * 461 = $428.73
a large water tank measures 6 feet across and 4 feet high. it is being filled with water at a rate of 10 gallons per minute. about how many hours will it take to fill the pool if 1 cubic feet of water is about 7.5 gallons? round to the nearest tenth.
At the given rate, it would take 1.2 hours to fill the tank described.
Calculating the VolumeTo find out how many hours it will take to fill the water tank, we need to calculate the volume of the tank and then determine the time it takes to fill it at a rate of 10 gallons per minute.
The volume of the tank can be calculated using the formula for the volume of a rectangular prism.
length x width x height:Volume = 6 feet x 4 feet x 4 feet = 96 cubic feet
Convert this volume to gallons, knowing that 1 cubic foot is about 7.5 gallons:
96 cubic feet x 7.5 gallons/cubic foot ≈ 720 gallonsSo, the tank has a capacity of approximately 720 gallons.
To find the time it takes to fill the tank at a rate of 10 gallons per minute:
Time (minutes) = Volume (gallons) / Rate (gallons per minute)
Time (minutes) = 720 gallons / 10 gallons per minute = 72 minutes
Now, to convert this to hours, divide by 60 (since there are 60 minutes in an hour):
Time (hours) = 72 minutes / 60 minutes per hour ≈ 1.2 hours
Rounded to the nearest tenth, it will take about 1.2 hours to fill the water tank.

To determine the time to fill the tank, calculate the tank volume in cubic feet, convert that to gallons, and then divide by the rate of water flow and 60 to get the time in hours.
Explanation:To determine how long it will take to fill the tank, we first need to calculate the volume of the tank in cubic feet. The tank is shaped like a cylinder, so the volume V of a cylinder is given by V = πr²h, where r is the radius and h is the height. In this case, the tank has a radius of 3 feet (half of the 6 feet diameter) and a height of 4 feet, so V = π(3)²(4) = π(9)(4) = 36π cubic feet.
Next, we need to consider that 1 cubic foot is equivalent to 7.5 gallons of water. Therefore, the tank capacity in gallons is 36π * 7.5.
We are told the tank is being filled at a rate of 10 gallons per minute. To determine how long it will take to fill the tank, we divide the total number of gallons the tank holds by the rate at which the tank is being filled. This will give the total time in minutes. To convert this time to hours, we then divide by 60, as there are 60 minutes in an hour.
So, the number of hours to fill the tank is (36π * 7.5) / 10 / 60, rounded to the nearest tenth.

100 POINTS! I need a thorough word problem that includes a quadratic formula. PLEASE!!!! I will give brainliest if you provide a clear explanation, as well. I really appreciate it :))
Answer:
Quadratic equations are actually used in everyday life, as when calculating areas, determining a product's profit or formulating the speed of an object. Quadratic equations refer to equations with at least one squared variable, with the most standard form being ax² + bx + c = 0.
Here is an example:
Antoine stands on a balcony and throws a ball to his dog, who is at ground level.
The ball's height (in meters above the ground), xxx seconds after Antoine threw it, is modeled by:

Hope that was helpful.Thank you!!!
Answer:
see below
Step-by-step explanation:
Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring. While factoring may not always be successful, the Quadratic Formula can always find the solution.
The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.
The Quadratic Formula is derived from the process of completing the square, and is formally stated as:
The Quadratic Formula: For ax2 + bx + c = 0, the values of x which are the solutions of the equation are given by:
-b ± [tex]\sqrt{b^2 - 4ac}[/tex]

Suppose that an urn contains 3 black marbles, 7 yellow marbles, and 10 green marbles. If one marble is selected, determine the probability that it is green. The answer should be an integer or a simplified fraction.
Answer:
1/2
Step-by-step explanation:
Simple probability is a ratio of the number of ways the thing we want to happen can to the total possible outcomes.
(For example, we flip a coin and want heads, but it can land on heads or tails. Our probability of getting heads is 1/2, one way to get heads over the 2 possible outcomes)
So for this problem, there's 20 possible things that CAN happen (3 + 7 + 10) and 10 ways we get what we want (a green marble).
Our probability of getting a green marble is [tex]\frac{10}{20\\}[/tex], which simplifies to [tex]\frac{1}{2}[/tex]
