The length of each side of a square is 3 in. more than the length of each side of a smaller square. the sum of the areas of the squares is 269 in squared . in2. find the lengths of the sides of the two squares.

Answers

Answer 1

The length of the side of the big square is 13 in. while that of the smaller square is 10 in.

Square

Square is a quadrilateral in which all the sides are equal to each other. Also opposite sides are parallel to each other and all angles measure 90 degrees.

Let a represent the length of the bigger square side and b represent the length of each side of the smaller square, hence:

a = b + 3   (1)

Also:

a² + b² = 269

(b + 3)² + b² = 269

2b² + 6b - 260 = 0

b = -13 or 10. Since b cannot be negative hence b = 10.

a = b + 3 = 10 + 3 = 13

The length of the side of the big square is 13 in. while that of the smaller square is 10 in.

Answer 2
Final answer:

To find the lengths of the sides of the two squares with a combined area of 269 square inches, where the larger square has sides 3 inches longer than the smaller square, we set up a quadratic equation based on the areas. Solving the equation gives us 10 inches for the smaller square and 13 inches for the larger square.

Explanation:

Finding the Lengths of the Sides of the Two Squares

We are given that the larger square has sides that are 3 inches longer than the sides of the smaller square and that the sum of their areas is 269 square inches. Let's denote the side length of the smaller square as s inches. Then, the side length of the larger square is (s + 3) inches.

The area of the smaller square is s^2, and the area of the larger square is (s + 3)^2. The sum of their areas is given by:

s^2 + (s + 3)^2 = 269

Expanding the equation gives us:

s^2 + s^2 + 6s + 9 = 269

Combining like terms, we get:


s^2 + s^2 + 6s + 9 - 269 = 0

2s^2 + 6s - 260 = 0

Dividing the entire equation by 2, we simplify to:

s^2 + 3s - 130 = 0

This is a quadratic equation that can be factored:

(s + 13)(s - 10) = 0

Setting each factor equal to zero gives us two possible solutions for s:

s + 13 = 0s - 10 = 0

The negative solution is not physically meaningful for the length of a side, so we discard s = -13 and take s = 10 inches as the side length of the smaller square. The larger square, therefore, has sides of 13 inches.

So, the side lengths of the two squares are 10 inches and 13 inches respectively.

Why would the owner withdraw assets from other cash?

Answers

Answer:

The owner of a business sometimes withdraw assets other than cash because cash is more liquid and can be used in transactions easily, whereas the assets after a period of times becomes liable of depreciation.

The depreciation on assets decreases the amount of the assets based on the time and wear and tear of the tangible assets.

Therefore, to retain some liquid assets in hand the tangible or intangible assets are used first.

A collection of nickels and dimes is worth $ 9.45. If the number of dimes is doubled, the value is $16.65. How many dimes and how many nickels?

Answers

The amount that the collections worth increased by was $7.20. That tells you how much the additional dimes are worth that was added to the $9.45. So if there is $7.20 in dimes, there are 72 dimes that were added to the collection of dimes and nickles. The 72 dimes that were added was the doubling of the number of dimes that are apart of the collection. That means that if there was 72 dimes all together, there were 35 dimes in the initial collection, which are worth $3.50, , and 35 dimes were added later. If the total collection was worth $9.45, and $3.50 of that was in dines, then the difference of $5.95, which is the amount the nickles were worth. That means that there were 19 nickles that were apart of the initial collection.

Joel borrowed $18,000 for 6 years at simple interest to purchase a vehicle. If Joel repaid a total of $20,953.80, at what rate did he borrow the money?

Answers

Final answer:

Joel borrowed money at an interest rate of approximately 2.73%. This was determined by using the simple interest formula to calculate the interest paid over 6 years and then re-formulating to find the interest rate using the known principal amount and time period.

Explanation:

The subject of this question is simple interest which is a concept in Mathematics. The question is asking for the interest rate at which Joel borrowed money to purchase a vehicle. By knowing that Joel borrowed $18,000, repaid a total of $20,953.80 after 6 years, and by applying the simple interest formula I = PRT (where I is interest, P is principal amount, R is interest rate and T is time in years), we can find out the interest rate.

The first step is to calculate the simple interest itself, which can be found by subtracting the original principal amount from the total amount repaid. So, $20,953.80 - $18,000 = $2,953.80 is the interest paid over 6 years.

Then we rearrange the simple interest formula to solve for the rate: R = I / (PT). Substituting the known values, our equation is: R = $2,953.80 / ($18,000 * 6), which gives R = 0.027325, or approximately 2.73% when expressed as a percentage.

To rent a bike there is a set fee, plus an hourly rate. Renting a bike for 4 hours costs $24. Renting it for 7 hours costs $37.50. How much to rent it for 3 hours?

Answers

I believe it's 13.05
Final answer:

By solving a system of linear equations, the set fee for renting a bike is determined to be $6 and the hourly rate is $4.50. Hence, the cost to rent the bike for 3 hours is $19.50.

Explanation:

The question involves creating linear equations based on the given information to find the cost of renting a bike for a certain number of hours. We are told that renting a bike for 4 hours costs $24 and renting for 7 hours costs $37.50. We can express this situation with two equations, where x represents the set fee and y represents the hourly rate:

4y + x = 247y + x = 37.5

We solve this system of equations to find the values of x and y. Subtracting the first equation from the second gives us 3y = 13.5, hence y = 13.5 / 3 = $4.50 per hour. We can then substitute y back into the first equation: 4(4.50) + x = 24, which simplifies to 18 + x = 24, hence x = $6.

To rent the bike for 3 hours, the cost would be 3(4.50) + 6 = $13.50 + $6 = $19.50.

A hummingbird can travel up to 15 meters per second. What is the hummingbirds speed in miles per hour? 1 mile = 1609 meters

Answers

Answer:

33.56 miles per hour.

Step-by-step explanation:

First we will see how many meters the hummingbird can travel in an hour (in meters)

it can travel up to 15 meters per second, but we know that one hour has 3600 seconds ( because an hour has 60 minutes of 60 seconds each one ( 60 x 60 = 3600)

So the hummingbird can travel 3600 x 15 = 54,000 meters in one hour.

Now, we know that 1 mile = 1609 meters, so in order to convert the 54,000 meters in miles per hour we're going to use a rule of three.

1 mile ----------- 1609 meters

x miles ---------- 54,000 meters

x miles = 54,000/1,609 = 33.56

Therefore, the hummingbird speed is 33.56 miles per hour.

Solving for b, we have the equation A(b)=12*(b+9)/2 - we cancel out 12 and the 1/2 to get 6(b+9)=A(b) and get 6b+54=A(b). Subtract 54 from both sides to get 6b=A(b)-54 and divide both sides by 6 to get b=A(b)/6-9 = A

The equation that represents the function B(a) as the length of the side parallel to the base is B(a) = a/6 - 9, as per the area of a trapezoid.

What is the area of a trapezoid?

If the length of two parallel sides of a trapezoid is 'a', 'b' and the height of that trapezoid is 'h', then the area of a trapezoid can be represented as

= [(a + b)h]/2

Given, the base of the trapezoid is 9 and the height of the trapezoid is 12.

Therefore, 'b' is the parallel side of the base.

The given function that represents the area of the trapezoid is:

A(b) = [12(b + 9)]/2

Let, A(b) = a.

Therefore, a =  [12(b + 9)]/2

⇒ 2a = 12(b + 9)

⇒ a = 6(b + 9)

⇒ a = 6b + 54

⇒ 6b = a - 54

⇒ b = (a - 54)/6

⇒ b = a/6 - 9

Alright, so what you would do is find the y intercepts of each function - make y=0, and solve it for each equation. If the y intercepts for 2x-3=y and x+4=y overlap with the y intercepts for y=2x^2+5x-12, it's right. For graphing the last two equations, you can simply plug in random values of x and get the output of y (for example, in x+4 you can plug in x=1 to get 1+4=5=y, getting (1,5) as one point) and in the same equation you can get 2 points and connect the dots. However, it's a bit different for 2x^2+5x-12 - you have to find the x value of the vertex (-b/2a=-5/4 in ax^2+bx+c) and plug it into the equation to get the y value. After that, you plug in one value greater than the x value of the vertex and one value smaller. Lastly, you connect it in kind of a U shape

Michael owns a lawn care service. He charges each customer 30 + 12h dollars, where h represents the number of hours spent working on a lawn. What does each part of the expression represent? Drag the answer into the box to match each part of the expression.

Answers

Final answer:

The linear  expression 30 + 12h represents Michael's lawn care service charges, where '30' is the fixed fee and '12h' is the variable fee depending on the hours worked.

Explanation:

Michael's lawn care service uses an equation to calculate the charges for his customers: 30 + 12h dollars, where h represents the number of hours spent working on a lawn. In this expression, the number 30 represents a fixed fee, likely covering base expenses such as equipment, transportation, or administrative costs. The term 12h represents the variable fee, where 12 is the hourly rate in dollars Michael charges for his labor, and h is the number of hours he works on the lawn.

Thus, to determine the total cost to a customer, one would multiply the number of hours Michael works (h) by his hourly rate (12) and then add the fixed fee (30). For instance, if Michael works 5 hours on a lawn, the total cost would be calculated as follows: 30 + 12(5) = 30 + 60 = 90 dollars.

When a linear system in three variables has infinitely many solutions, it means that the three equations are dependent on each other and represent the same line or plane. This happens when the coefficients of the variables in the equations are proportional to each other. To determine if a system has infinitely many solutions, we can solve the system and check if any of the equations can be derived from the others or if they represent the same line or plane.



Let's take the system of equations given in the question:

7y = 6x + 84y = 8y + 7 = 3x

We can start by solving equations (1) and (2) for y:

7y = 6x + 8  (equation 1)4y = 8  (equation 2)

Simplifying equation (2), we get:

y = 2

Substituting y = 2 into equation (1), we have:

7(2) = 6x + 8

14 = 6x + 8

6x = 14 - 8

6x = 6

x = 1

Now, let's substitute the values of x and y into equation (3):

y + 7 = 3x

2 + 7 = 3(1)

9 = 3

This equation is not true. Therefore, the system of equations is inconsistent and does not have infinitely many solutions. The system does not represent the same line or plane.
