A 12 foot ladder is placed 4 foot from the bottom of the house. How high will the ladder reach the house?
Answer:
11.31 ft
Step-by-step explanation:
Here in this problem ladder forms a right triangle with the wall of the house and it is acts as hypotenuse, length of one leg of right triangle given to be 4 feet.
Let the ladder reaches x ft height of the house.
Hence, by Pythagoras theorem:
[tex] {12}^{2} = {4}^{2} + {x}^{2} \\ 144 = 16 + {x}^{2} \\ {x}^{2} = 144 - 16 \\ {x}^{2} = 128 \\ x = \sqrt{128} \\ x = 11.3137085 \\ x = 11.31 \: ft[/tex]
Hence, the ladder reaches 11.31 ft height of the house.

Which of the following shows the correct order of the numbers?
..0.8
The correct answer is: A. -1.3, -1.2, 0.8, 0.9. Hence the correct option is a.
Start by comparing the negative numbers:
Since -1.3 is a smaller number than -1.2, we know -1.3 comes first.
Compare the negative numbers with the positive numbers:
All negative numbers are less than any positive number. Therefore, both -1.3 and -1.2 come before 0.8 and 0.9.
Compare the positive numbers:
Finally, compare 0.8 and 0.9. Since 0.9 is larger, it comes last.
Therefore, the order from least to greatest is: -1.3, -1.2, 0.8, 0.9. This corresponds to option A.

if there are 10 apples in the fridge and 7 on the table what is the ratio of apples in the fridge to apples on the table
Answer:
The correct answer would be 10 : 7
( OPINION ) I say this because we are comparing the apples in the fridge(10) to the apples on the table(7).
I hope this was helpful :3
STAY SAFE!! :)
The ratio of apples in the fridge to apples on the table is 10:7. This is calculated by dividing the number of apples in the fridge by the number on the table.
Explanation:The question asks for the ratio of apples in the fridge to the apples on the table. In order to solve this, you need to understand what a ratio is. A ratio is a way of comparing quantities. Here, the quantity being compared is apples: those in the fridge versus those on the table.
To calculate the ratio, you simply divide the first quantity by the second quantity. So in this case, you have 10 apples in the fridge and 7 apples on the table.
The ratio is therefore 10/7. This can also be written as 10:7.

a round clock has a radius of 5 cm. what is the approximate area of the clock? use 3.14
Answer:
78.5 cm^2
Step-by-step explanation:
The area of a circle can be found using:
[tex]a=\pi r^2[/tex]
We know that the radius is 5 cm. We also know that we are using 3.14 for pi. Therefore, we can substitute 5 in for r, and 3.14 in for pi.
a=3.14*5^2
Evaluate the exponent
a=3.14*(5*5)
a=3.14*25
Multiply
a=78.5
The area of the clock is 78.5 cm^2
£ represents a group of 30 people that visited paris for a weekend break. 13 of the group visited the eiffel tower (ET) 16 of the group visited the no tre-dame cathedral (NDC) 7 of the group did not visit either of these places a person is chosen at random from the group. what is the probability that this person only visited one of the two places?
Answer:
Step-by-step explanation:
The probability that a person chosen at random from a group of 30 people only visited one of the two landmarks, the Eiffel Tower or the Notre-Dame Cathedral in Paris, is 17/30.
To calculate the probability that a person in a group of 30 people who visited Paris only visited one of the two landmarks - the Eiffel Tower (ET) or the Notre-Dame Cathedral (NDC), we need to apply the principles of set theory and probability.
Firstly, we know that:
13 visited the ET
16 visited the NDC
7 did not visit either place
Adding the numbers of visitors to both places gives us a total of 29 (13 ET + 16 NDC). However, the total number of people is 30, and 7 did not visit either, which implies that 23 people (30 - 7) visited at least one site. Therefore, 29 - 23 gives us 6 people who have visited both places.
To find the number who visited only one place, we subtract those who visited both from the total who visited each:
For ET only: 13 (visited ET) - 6 (visited both) = 7
For NDC only: 16 (visited NDC) - 6 (visited both) = 10
Adding these gives us 17 (7 ET only + 10 NDC only) who visited just one site. Hence, the probability that a person chosen at random visited only one of the two places is:
P(visited only one site) = Number who visited only one site / Total number of people
P(visited only one site) = 17 / 30
Therefore, the probability is 17/30.

The values of [tex]\( \sin \theta \)[/tex] are [tex]\( \frac{\sqrt{35}}{6} \)[/tex] and [tex]\( -\frac{\sqrt{35}}{6} \)[/tex], and the value of [tex]\( \tan \theta \)[/tex] is [tex]\( \sqrt{35} \)[/tex].
Given that [tex]\( \cos \theta = \frac{1}{6} \)[/tex], we need to find [tex]\( \sin \theta \)[/tex] and [tex]\( \tan \theta \)[/tex].
First, we can find [tex]\( \sin \theta \)[/tex] using the Pythagorean identity:
[tex]\[\sin^2 \theta + \cos^2 \theta = 1\][/tex]
Substitute [tex]\( \cos \theta = \frac{1}{6} \)[/tex]:
[tex]\[\sin^2 \theta + \left(\frac{1}{6}\right)^2 = 1\][/tex]
[tex]\[\sin^2 \theta + \frac{1}{36} = 1\][/tex]
[tex]\[\sin^2 \theta = 1 - \frac{1}{36} = \frac{36}{36} - \frac{1}{36} = \frac{35}{36}\][/tex]
[tex]\[\sin \theta = \pm \sqrt{\frac{35}{36}} = \pm \frac{\sqrt{35}}{6}\][/tex]
So, [tex]\( \sin \theta \)[/tex] could be [tex]\( \frac{\sqrt{35}}{6} \)[/tex] or [tex]\( -\frac{\sqrt{35}}{6} \)[/tex].
Next, to find [tex]\( \tan \theta \)[/tex], we use the definition:
[tex]\[\tan \theta = \frac{\sin \theta}{\cos \theta}\][/tex]
Substitute [tex]\( \sin \theta = \pm \frac{\sqrt{35}}{6} \) and \( \cos \theta = \frac{1}{6} \)[/tex]:
[tex]\[\tan \theta = \frac{\frac{\sqrt{35}}{6}}{\frac{1}{6}} = \sqrt{35}\][/tex]

Find how many six-digit numbers can be formed from the digits 2, 3, 4, 5, 6 and 7 (with repetitions), if:
the numbers formed must be divisible by 25
or
the odd digits must occupy even positions (i.e. 2nd, 4th, and 6th) and the even digits must occupy odd positions (i.e. 1st, 3rd and 5th)
Answer:
case 1 = 2592
case 2 = 729
case 1 + case 2 = 2916
(this is not a direct adition, because case 1 and case 2 have some shared elements)
Step-by-step explanation:
Case 1)
6 digits numbers that can be divided by 25.
For the first four positions, we can use any of the 6 given numbers.
For the last two positions, we have that the only numbers that can be divided by 25 are numbers that end in 25, 50, 75 or 100.
The only two that we can create with the numbers given are 25 and 75.
So for the fifth position we have 2 options, 2 or 7,
and for the last position we have only one option, 5.
Then the total number of combinations is:
C = 6*6*6*6*2*1 = 2592
case 2)
The even numbers are 2,4 and 6
the odd numbers are 3, 5 and 7.
For the even positions we can only use odd numbers, we have 3 even positions and 3 odd numbers, so the combinations are:
3*3*3
For the odd positions we can only use even numbers, we have 3 even numbers, so the number of combinations is:
3*3*3
we can put those two togheter and get that the total number of combinations is:
C = 3*3*3*3*3*3 = 3^6 = 729
If we want to calculate the combinations togheter, we need to discard the cases where we use 2 in the fourth position and 5 in the sixt position (because those numbers are already counted in case 1) so we have 2 numbers for the fifth position and 2 numbers for the sixt position
Then the number of combinations is
C = 3*3*3*3*2*2 = 324
Case 1 + case 2 = 324 + 2592 = 2916

What is exponent?The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.
In mathematics, a base number raised to an exponent is referred to as a power. The base number is the factor that is multiplied by itself, and the exponent indicates how many times the base number has been multiplied.
Given,
Equation = [tex](1/5000)^{2z}X5000^{2z+2}[/tex]
We have to rewrite the given equation so there is a single power of 5,000 on each side.
[tex]1/a^n=a^{-n}\\\\a^m/a^n=a^{a-n}\\\\a^mXa^n=a^{m+n[/tex]
So,
[tex](1/5000)^{2z}X5000^{2z+2}=5000[/tex]
[tex]5000^{-2z}X5000^{2z+2}=5000[/tex]
[tex]5000^{-2z+2z+2}=5000^1[/tex]
By this,
-2z+2z+2=1,
Thus, the value can be 2=1, so the correct option is A.

Bob's Burgers surveyed a random sample of 70 Sunset Park Food Festival
attendees about their favorite type of burger. Of the attendees surveyed,
32 said that bacon cheeseburgers were their favorite type of burgers.
There are 1400 Sunset Park Food Festival attendees. Based on the data,
what is the most reasonable estimate for the number of Sunset Park Food
Festival attendees whose favorite type of burger is a sausage bacon
cheeseburger? *
Answer:
The most reasonable estimate for the number of Sunset Park Food Festival attendees whose favorite type of burger is a sausage bacon cheeseburger is 760.
Step-by-step explanation:
Assume that Bob's Burgers provides two types of burgers:
Bacon cheeseburgers (B)Sausage bacon cheeseburger (S)Of the random sample of N = 70 attendees, the number of people who said that bacon cheeseburgers were their favorite type of burgers is 32.
Then the number of people who said that sausage bacon cheeseburgers were their favorite type of burgers is, n (S) = 70 - 32 = 38.
Compute the probability that a randomly selected attendee like sausage bacon cheeseburger as follows:
[tex]P(S) = \frac{n(S)}{N}=\farc{38}{70}=0.543[/tex]
It is provided that there are 1400 Sunset Park Food Festival attendees.
Let the random variable X be defined as the number of attendee who likes sausage bacon cheeseburgers.
Then the random variable X will follows a Binomial distribution with parameter n = 1400 and p = 0.543.
This is because, there are a fixed number of trial in the experiment, each trial has the same number of outcomes, i.e. a person either likes bacon cheeseburgers or sausage bacon cheeseburgers and each trial has the same probability of success, i.e. P (S).
The expected value of a Binomial random variable is:
[tex]E(X)=n\times p[/tex]
Compute the expected number of attendees whose favorite type of burger is a sausage bacon cheeseburger as follows:
[tex]E(X)=n\times p[/tex]
[tex]=1400\times 0.543\\=760.2\\\approx 760[/tex]
Thus, the most reasonable estimate for the number of Sunset Park Food Festival attendees whose favorite type of burger is a sausage bacon cheeseburger is 760.
