A 45 foot ladder is used to clean the
gutters at your house. How far away from
the house should you put the ladder in
order for it to reach the 40 foot high
gutter? Round your answer to the nearest
tenth.
5 feet.
Answer:
20.62
Step-by-step explanation:
In this instance, we are going to use the pythagorean theorem.
The height of the gutter will be a leg of the triangle, and the ladder will be the hypotenuse. The formula is
[tex]a^{2} + {b}^{2} = {c}^{2} [/tex]
While A and B are legs and C is the hypotenuse. We are trying to find B, the distance from the house.
So plug A and C in:
[tex] {40}^{2} + {b}^{2} = {45}^{2} [/tex]
Now figure it out: first you square 40 and 45:
[tex]1600 + {b}^{2} = 2025[/tex]
Isolate the B term: subtract 1600 from both sides
[tex] {b}^{2} = 425[/tex]
Now take the square root of both sides to find B
[tex]b = 20.62[/tex]
And that's your answer
Answer:
20.6 feet
Step-by-step explanation:
The Pythagorean theorem can tell you the distance from the house the base of the ladder may be for it to reach 40 feet up. If that distance is represented by x, then it tells you ...
45^2 = x^2 + 40^2
x = √(2025 -1600) = √425
x ≈ 20.6
The ladder will reach to 40 feet high when the base is 20.6 feet from the house.
_____
Comment on ladder distance
The ladder safety association recommends an angle with the ground of about 75°. That corresponds to a distance from the house of about 10 feet. If the ladder is 20 feet away, it will barely reach the gutter, so placing it at that distance would probably not be safe.
An appropriate answer to this question is "10 feet", not based on math, but based on safety. At that distance the end of the ladder will extend about 3.7 feet beyond the gutter.

Whats the product of 2/3 × 36
Answer:
24 :)
Step-by-step explanation:
2 / 3 x 36 = ?
First of all, note that 36 is the same as 36/1 since 36 divided by 1 is 36. Therefore, start by setting up the problem like this:
36 / 1 x 2 / 3
Multiply the numerators together (36 x 2 = 72) and multiply the denominators together (1 x 3 = 3) and make it into one fraction like so:
72 / 3
The greatest common factor of 72 and 3 is 3. Minimize the fraction by dividing the numerator and the denominator by its greatest common factor to get:
24 / 1
Convert the improper fraction above to a whole number to get the answer:
24

An=a^1*r^n-1 that’s the formula for the equation I kinda dunno how to exactly solve it though
Answer:
see explanation
Step-by-step explanation:
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]
where a is the first term and r the common ratio
Here a = 15, thus
[tex]a_{5}[/tex] = 15[tex](r)^{4}[/tex] = [tex]\frac{243}{125}[/tex] ( divide both sides by 15 )
[tex]r^{4}[/tex] = [tex]\frac{243}{1875}[/tex], thus
r = [tex]\sqrt[4]{\frac{243}{1875} }[/tex] = [tex]\frac{3}{5}[/tex]
Multiply the previous term by [tex]\frac{3}{5}[/tex] to obtain the next term
15 × [tex]\frac{3}{5}[/tex] = 9
9 × [tex]\frac{3}{5}[/tex] = [tex]\frac{27}{5}[/tex]
[tex]\frac{27}{5}[/tex] × [tex]\frac{3}{5}[/tex] = [tex]\frac{81}{25}[/tex]
[tex]\frac{81}{25}[/tex] × [tex]\frac{3}{5}[/tex] = [tex]\frac{243}{125}[/tex]
Thus the sequence is
15, 9, [tex]\frac{27}{5}[/tex], [tex]\frac{81}{25}[/tex], [tex]\frac{243}{125}[/tex]

Find the sum of the interior angles of a decagon
Answer:
1440 degrees
Step-by-step explanation:
The sum of the interior angles of a polygon can be found by
(n-2)*180
where n is the number of sides
a decagon has 10 sides, so n=10
(10-2) *180
8*180
1440
The sum of all the interior angles of a decagon is calculated as (n-2) × 180°. For a decagon, where n is 10, the sum is 1440°.
The correct option is (C).
The sum of all the interior angles of a decagon can be found using the formula for calculating the sum of interior angles of any polygon, which is (n-2) × 180°, where n is the number of sides of the polygon. In the case of a decagon, n is 10. Therefore, the sum of all the interior angles of a decagon is (10-2) × 180° = 8 × 180° = 1440°. Thus, the correct answer is C.1440°.
complete question given below:
The sum of all the interior angles of a decagon is
A.1000∘
B.960∘
C.1440∘
D.1200∘
Write two different mixed numbers where the LCD (lowest common denominator) is 12
Two mixed numbers as [tex]\frac{5}{6}[/tex] and [tex]\frac{5}{12}[/tex] the least common denominator (LCD) is 12.
Step-by-step explanation:
The least common denominator (LCD) is the smallest number that can be a common denominator for a set of fractions. Also known as the lowest common denominator, it is the lowest number you can use in the denominator to create a set of equivalent fractions that all have the same denominator.
Steps to find the LCD of fractions, integers and mixed numbers:
Convert integers and mixed numbers to improper fractionsFind the LCD of all the fractionsRewrite fractions as equivalent fractions using the LCDLet's us have two mixed numbers as [tex]\frac{5}{6}[/tex] and [tex]\frac{5}{12}[/tex].
Equivalent Fractions with the LCD
[tex]\frac{5}{6}[/tex] = [tex]\frac{10}{12}[/tex]
[tex]\frac{5}{12}[/tex] = [tex]\frac{5}{12}[/tex]
For the denominators (6, 12) the least common multiple (LCM) is 12. Therefore, the least common denominator (LCD) is 12.
Final answer:
The mixed numbers 1 1/4 and 2 1/3 can be converted to have the lowest common denominator of 12, resulting in 1 3/12 and 2 4/12 respectively.
Explanation:
To write two different mixed numbers where the lowest common denominator (LCD) is 12, we can choose denominators that are factors of 12 and numerators that result in proper fractions (where the numerators are less than the denominators). An example would be 1 1/4 and 2 1/3. Here's how these mixed numbers have 12 as their common denominator:
For 1 1/4, the denominator 4 is a factor of 12. To convert 1/4 to a denominator of 12, multiply the numerator and denominator by 3. So, 1 1/4 becomes 1 3/12.For 2 1/3, the denominator 3 is also a factor of 12. To convert 1/3 to a denominator of 12, multiply the numerator and denominator by 4. So, 2 1/3 becomes 2 4/12.Now we have two mixed numbers with the LCD of 12.

Y=3x+13
Y=x-3
Answer:
x = -8
Y = -11
Step-by-step explanation:
Given
Y = 3x + 13
Y = x - 3
Substitute x - 3 for Y in the first equation
We have
Y = 3x + 13
x - 3 = 3x + 13
Add 3 to both sides
x - 3 + 3 = 3x + 13 + 3
x = 3x + 16
Subtract 3x from both sides
x - 3x = 3x - 3x + 16
-2x = 16
Divide both sides by -2
x = 16/-2
x = -8
Now substitute -8 for x in any of the above equations to get Y.
Using the second equation, we have
Y = x - 3
Y = -8 - 3
Y = -11
Without multiplying, tell which is greater: 4/5 x 45 or 2/3 x 45. Explain.
Answer: It is 4/5 x 45
Step-by-step explanation: Hope i helped please mark brainliest!
I know there is suppose to be no multiplying but if you mulitply in your head 4/5 x 45 is 36 and 2/3 x 45 is 30
therefore, 4/5 x 45 is greater!
also, if not multiplying 0.8(5/4) is greater than 0.667(2/3). Therefore, 4/5 is greater than 2/3.
Without multiplying, 4/5 x 45 is greater than 2/3 x 45 because the fraction 4/5 is greater than 2/3 when both are compared using a common denominator.
Explanation:To answer which is greater without multiplying, we can look at the fraction multiples of 45 in the problems 4/5 x 45 and 2/3 x 45. Since both expressions involve the same whole number (45), we can compare the fractions 4/5 and 2/3 to determine which product is greater. By converting the fractions to have a common denominator, we can see that 4/5 is equivalent to 24/30, and 2/3 is equivalent to 20/30. Therefore, 4/5 is greater than 2/3, meaning that 4/5 x 45 is greater than 2/3 x 45.

Given the parent function f(x)=|x|, which equation would occur if the function is vertically compressed by 13, shifted down 6 units, and shifted right 5?
f(x)=3|x+5|−6
f(x)=13|x−5|−6
f(x)=13|x+5|−6
f(x)=13|x−6|+5
[tex]f(x)=13|x-5|-6[/tex] is the equation represented by all the operations.
Step-by-step explanation:
The given function is
[tex]f(x)=|x|[/tex]
It is vertically compressed by a factor of 13 then the function becomes,
[tex]f(x)=13|x|[/tex]
It shifted down 6 units, then the function becomes,
[tex]\mathbf{f}(\mathbf{x})=\mathbf{1 3}|\boldsymbol{x}|-\boldsymbol{6}[/tex]
It shifted right by 5 units then the function becomes,
[tex]f(x)=13|x-5|-6[/tex]
Thus the resultant equation thus obtained is [tex]f(x)=13|x-5|-6[/tex]

Before lunch, they assembled 15 regular wreaths and 15 deluxe wreaths, which used a total of 135 pinecones. After lunch, they assembled 15 regular wreaths and 20 deluxe wreaths, using a total of 160 pinecones. How many pinecones are they putting on each wreath?
Answer:
5 pinecones on the deluxe wreath and 4 pinecones on the regular wreath
Step-by-step explanation:
Answer:
Regular: 4
Deluxe: 5
Step-by-step explanation:
15x + 15y = 135
15x + 20y = 160
5y = 25
y = 5
15x = 135 - 15(5)
15x = 60
x = 4
Stacy uses a spinner with six equal sections numbered 2, 2, 3, 4, 5, and 6 to play a game. Which of the following statements is true? Select all that apply. A. The probability of the pointer landing on an even-numbered section is 66.67%. B. It is impossible that the pointer will land on 1. C. It is less likely that the pointer will land on an odd-numbered section. D. It is certain that the pointer will land on a number less than 6. E. The spinner is fair.
Answer:
A, B and C are the correct answers.
Step-by-step explanation:
Correct:
A - There are 4 even numbers all together. 2 is repeated twice, there is a 4 and a 6. 4 divided by 6 is 0.666 repeated. Multiply by 100 which gives you 66.666 repeated and then round up, so now we have 66.67%. This is the probability.
B - It’s impossible that the pointer will land on 1 because there in no 1.
C - It’s less likely because there are only two odd numbers, 3 and 5. Compare that to the 4 even numbers. 4 > 2. Therefore the odd numbers, or the two, is less likely than the even numbers, the 4.
Incorrect:
D - There is only one 6 out of 6 numbers total. So 1 out of 6. We cannot be certain, it fact, it would be said that it’s very unlikely for the pointer to land on the 6.
E - The spinner is most certainly not fair. The spinner has one of each number except for the 2. There are double twos. On a normal spinner you would see a number 1 replace on of the 2. This ways the spinner will be 1 through 6.
If it makes any of you more confident in this answer, my assessment also had this question and I got it correct by answering with A, B and C.
Final answer:
The probability of the pointer landing on an even-numbered section is 33.33%. The pointer can't land on 1. The spinner is not fair.
Explanation:
To find the probabilities in this scenario, we need to analyze the spinner. The spinner has 6 equal sections, numbered 2, 2, 3, 4, 5, and 6. There are:
2 even-numbered sections (2 and 4)3 odd-numbered sections (2, 3, and 5)1 section with a number less than 6 (4)Based on this analysis, we can determine the following statements:
Statement A is false: The probability of the pointer landing on an even-numbered section is 33.33% (2 out of 6 possibilities).Statement B is true: The pointer can't land on 1 because it is not one of the numbered sections on the spinner.Statement C is false: The probability of the pointer landing on an odd-numbered section is 50% (3 out of 6 possibilities), which is the same as the probability of landing on an even-numbered section.Statement D is true: The pointer will certainly land on a number less than 6 because all the numbered sections on the spinner are less than 6.Statement E is false: The spinner is not fair because the probabilities of landing on different sections are not equal.Call an integer $n$ oddly powerful if there exist positive integers $a$ and $b$, where $b>1$, $b$ is odd, and $a^b = n$. How many oddly powerful integers are less than $2010$?
Answer:
There are 16 oddly powerful integers less than 2010
Step-by-step explanation:
∵ b is an odd integer
∵ b > 1
∴ The first value of b is 3
∵ a is an integer
- We can use a = 1, 2, 3, ..........
∵ [tex]a^{b}=n[/tex]
∵ n < 2010
- Let a = 1, 2, ............... 12 because 12³ is greatest integer < 2010
∵ 1³ = 1, 2³ = 8, 3³ = 27, 4³ = 64, 5³ = 125, 6³ = 216, 7³ = 343,
8³ = 512, 9³ = 729, 10³ = 1000, 11³ = 1331, 12³ = 1728
∴ There are 12 oddly powerful integers with b = 3
Now the second value of b is 5
[tex]1^{5}=1[/tex] but we took 1 before so we will start with 2
∵ [tex]2^{5}=32[/tex], [tex]3^{5}=243[/tex], [tex]4^{5}=1024[/tex]
- [tex]4^{5}[/tex] is the greatest integer < 2010
∴ There are 3 oddly powerful integers with b = 5
Now the third value of b is 7
∵ [tex]2^{7}=128[/tex]
- [tex]2^{7}[/tex] is the greatest integer < 2010
∴ There is 1 oddly powerful integers with b = 7
Now the fourth value of b is 9
∵ [tex]2^{9}=512[/tex]
- [tex]2^{9}[/tex] is the greatest integer < 2010
- But we used 512 before
∴ There is no oddly powerful integers with b = 9
- 9 is the greatest value of b which makes [tex]a^{b}<2010[/tex]
∵ 12 + 3 + 1 = 16
∴ There are 16 oddly powerful integers less than 2010

At a campground, a rectangular fire pit is 3 feet by 2 feet. What is the area of the largest circular fire that
can be made in this fire pit? Use 3.14 for it. Round to the nearest square Inch.
The area of the largest circular fire pit is 452 square inches.
Explanation:
Given that at a campground, a rectangular fire pit is 3 feet by 2 feet
The radius is given by 1 feet.
Area:
The area of the largest circular fire is given by
[tex]A=\pi r^2[/tex]
Substituting the values in the formula, we get,
[tex]A=(3.14)1^2[/tex]
[tex]A=3.14 \ ft^2[/tex]
Thus, the area of the largest circular fire is 3.14 square feet.
To convert feet to inches:
The feet can be converted into inches by multiplying by 12.
Thus, we have,
[tex]1 \ft= 12 \ inches[/tex]
Hence, we have,
[tex]Area= 3.14\times 12^2[/tex]
Simplifying,we get,
[tex]Area= 3.14\times144[/tex]
[tex]Area=452.16 \ in^2[/tex]
Rounding off to the nearest square inch.
Thus, we have,
[tex]Area= 452 \ in^2[/tex]
Thus, the area of the largest circular fire pit is 452 square inches.

Grandma says Baby Bertha (BB) should get $1000 at birth plus $50 per year. Grandpa disagrees; he thinks BB should get $1000 at birth plus an additional 4% of the accumulated amount each year. Grandma and Grandpa will continue to contribute additional funds into the account as long as BB doesn’t make a withdrawal. Which option should BB’s parents select? Why?
BB's parents should choose Grandpa's option, where Baby Bertha (BB) receives $1000 at birth plus an additional 4% of the accumulated amount each year.
Explanation:In Grandpa's option, the annual contribution grows dynamically with the accumulated amount, creating compounding growth. Let's denote the accumulated amount at the end of year \(n\) as A_n. The contribution at year \(n\) can be expressed as \(0.04 \times A_n\). BB's total amount at the end of year \(n\) can be written as:
\[A_n = 1000 \times (1 + 0.04)^{n}.\]
This formula considers the initial $1000 and the 4% annual growth on the accumulated amount. With compounding, this option ensures that BB's fund grows significantly over time.
Grandma's option, on the other hand, provides a fixed annual amount of $50, which does not consider the potential growth through interest or investment. Over time, the fixed contribution might not keep up with inflation, and the fund may not accumulate as much as Grandpa's option.
In summary, Grandpa's option is financially advantageous due to compounding growth, allowing BB's fund to grow more substantially over the years. This strategy aligns with long-term financial planning, providing a better financial foundation for Baby Bertha's future.

A computer programmer worked for 10 hours and earned $70,which is a rate of dollars per hour.
When a programmer works for 10 hours and earns $70, the rate of dollars per hour earned by the programmer is $7.
A computer programmer worked for 10 hours and earned $70.
To calculate the rate per hour, we divide the total earnings by the number of hours worked. In this case,
$70 ÷ 10 hours = $7 per hour.
Therefore, the programmer earned $7 per hour.
Use the Distributive Property to solve the equation
4(x+2)=16
Answer:
Step-by-step explanation:
4(x+2) = 16
4x + 8 = 16
4x =16-8
4x = 8
x = 8/4
x = 2
The solution to the equation 4(x + 2) = 16 is x = 2.
The Distributive Property states that a(b + c) = ab + ac. Apply this to the equation:
4(x + 2) = 4 * x + 4 * 2.
Thus, the equation becomes:
4x + 8 = 16.
To solve for x, first subtract 8 from both sides of the equation:
4x + 8 - 8 = 16 - 8
4x = 8.
Divide both sides of the equation by 4:
4x / 4 = 8 / 4
x = 2.
