2. Length of b is I: 5
3. Length of C is A: 7.94
4. Area of d is B: 35.73
Where can the Pythagorean theorem be used to find the lengths and areas of a figure?1. Given;
The area of the side squares are; 9 m² and 16 m²
According to Pythagorean theorem, we have;
Area of square a = 9 m² + 16 m² = 25 m²
Area of a is H: 252. b² = Area of side square a
Therefore;
b = √(25 m²) = 5 m
Length of b is I: 53. Given;
Area of the squares adjacent to the hypotenuse side and a leg are;
144 m² and 81 m² respectively
According to Pythagorean theorem, we have;
C² = 144 m² - 81 m² = 63 m²
C = √(63 m²) = √(9 × 7 m²) = 3·√7 m ≈ 7.94 m
Length of C is A: 7.944. Area of triangle d = \(\frac{1}{2}\) × √(81 m²) × 7.94 m ≈ 35.73 m

Answers
Answer: The relationship between the decimals for 2/6 and 4/6 is that the decimal for 4/6 is twice the decimal for 2/6.
When we simplify 2/6, we get 1/3, which is equivalent to 0.33 as a decimal. When we simplify 4/6, we get 2/3, which is twice the value of 1/3. So the decimal for 4/6 is twice the decimal for 2/6, which means that they have a proportional relationship.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.
3x - 5y = -35
please solve and show your work
Answers
First you subtract 3x to both sides.
3x - 5y = -35
-3x -3x
Then it would be
-5y = -3x -35
Then you divide -5 on both sides to isolate the y
-5y = -3x -35
/-5 /-5 /-5
Two negatives cancel out and make a positive so it would be

The state of colorado is 4 cm long and 3 cm wide on a map. A cartographer wants to use a scale factor of 2.5 to enlarge the map. What is the area of the enlarged map?
A:12 square cm
B:30 square cm
C:35 square cm
D:75 square cm
Answers
Answer:
D. 75 cm²
Step-by-step explanation:
We are asked to find the area of a scaled map.
What is a Scale Factor?A scale factor is a change in the size, or ratio of a shape, or object.
The value of the scale factor represents how much larger the shape or object will become.
First, let's identify what is given to us.
Given:
The map of Colorado is 4 cm long and 3 cm wide.We have to enlarge the map with a scale factor of 2.5.We should begin by enlarging the map with the given scale factor. In order to find the dimensions of the scaled map, we should multiply the given dimensions of the original map by the scale factor.
Multiply:
\(4 \times 2.5 = 10 \ cm\)
\(3 \times 2.5 = 7.5 \ cm\)
Next, we should find the area of the scaled map by multiply the dimensions together.
\(A = L \times W\)
Multiply:
\(A = 10 \times 7.5\)
\(A = 75 \ cm^{2}\)
The area of the scaled map is D. 75 cm².

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

Answers
Answer:
To find the answer to all questions do this....
Step-by-step explanation:
Solving problem #1 as an example:
-Set up an equation with two "fractions" equal to eachother.
-have the total amount (196) equal 100
ex. ?/196 = ?/100
-then find the percentage asked b placing the percent over 100
ex. 5/100
- from there solve by multiplying the percent (5) to the total amount (196) and divide that answer by 100.
-finally you should get your answer of 9.8
*** to check your work simply set up your answers
ex. 9.8/196 = 5/100
and multiply the numbers diagonally from eachother
ex. 9.8×100 and 196×5
If your answer is correct, you should get the same number on both sides
980=980
Number 264.5
Number 3 .8

Answer:
addition is the answer because all of the other equations will have the same x value
Answer: Step 1 is solved incorrectly.
Step-by-step explanation:
-4(3x+6) +6=-30
= -12x-24+6=-30
and not
-12x-12+6=-30.
The real solution is x=1. Here is how:
−4(3x+6)+6=−30
Use the distributive property to multiply −4 by 3x+6.
−12x−24+6=−30
Add −24 and 6 to get −18.
−12x−18=−30
Add 18 to both sides.
−12x=−30+18
Add −30 and 18 to get −12.
−12x=−12
Divide both sides by −12.
x=−12−12
Divide −12 by −12 to get 1.

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.
