Pythagorean Theorem
FIRST TO ASNWER WILL GET THANKS AND WILL BE MARKED BRAINLIEST
Answer:
b=17.75 ft
Step-by-step explanation:
We will answer this using Pythagorean Theorem.
Since the bottom of a ladder is 3 feet from the wall, and the ladder is 18 ft long, the ladder is the hypotenuse. Knowing pythagorean theorem (a^2+b^2=c^2), we can plug it in.
3^2 + b^2 = 18^2
9+b^2=324
b^2=315
b=17.75 ft

( 12y + 2x) + 4y simplify the expression
Answer:
[tex]2x+16y[/tex]
Add [tex]12y[/tex] and [tex]4y[/tex].
[tex]2x+16y[/tex]
Answer:
2x + 16y
Step-by-step explanation:
The y terms can be added together. 12y + 4y is 16y. The 2x has to just stay the way it is because it could only be added to another x term and there aren't any. So you are left with 2x + 16y

A study was conducted about the number of miles that a sample of automobiles in New York City drive within a year. The sample was taken in front of an apartment complex and included 20 taxicab drivers and 40 of the building’s residents. Which is a reasonable explanation for the large gap in the histogram?
The histogram includes data from a voluntary response sample which is not representative of the population.
How to interpret Histograms?
A histogram is a chart that represents numerical data using bars. The dataset is split into intervals, each interval is represented by a bar, and the number of variables in each interval makes up the frequency for that interval.
From the histogram attached, we can see that there is a huge gap from around 17000 miles to 32500 miles.
Now, when we have this kind of gap it means that the histogram includes data from a voluntary response sample which is not representative of the population.

Which addition does the model below represent?
5 positive tiles and 3 negative tiles.
Any time we have a single positive tile pair up with a single negative tile, those two tiles cancel out.
Three positive tiles and three negative tiles will pair up and cancel out. We're left with two positive tiles only. This represents the number 2.
In other words, 5 + (-3) = 5 - 3 = 2
What is the value of x in the figure below?
Answer:
The value of x in the figure is 3.5
Step-by-step explanation:
When we look at the figure, we see that AB and BC, are connected, to make a longer side of a triangle. We can also see that BC is dilated from AB. When dilating, we multiply or divide by a number, to get the extended or shortened length. (Just keep multiplication and division in mind) To get x, we can do the same that we did to get 2, from 4. From AB to BC it goes from 4 to 2.
To get 2 from 4, you must divide 4 by 2. So when we do the same thing to 7, we should get x.
7 / 2 = 3.5
The value of x in the figure is 3.5
[tex]\\ \rm\dashrightarrow \dfrac{4}{2}=\dfrac{7}{x}[/tex]

The sum of multiples of five from 10 to 75, inclusive.
The asked sum of multiples of five from 10 to 75, inclusive, is 595.
To find the sum of multiples of five from 10 to 75, inclusive, we can use the formula for the sum of an arithmetic series:
Sum = (n/2) * ([first term] + [last term])
Following the given case, the first term (a) is 10, the last term (l) is 75, and the common difference (d) between consecutive terms is 5 (since we are considering multiples of five).
The number of terms (n) can be calculated as:
n = (last term - first term) / common difference + 1
Let's calculate the number of terms first:
n = (75 - 10) / 5 + 1
n = 65 / 5 + 1
n = 13 + 1
n = 14
Now, we can determine the sum of the multiples of five:
Sum = (14/2) * (first term + last term)
Sum = 7 * (10 + 75)
Sum = 7 * 85
Sum = 595
Therefore, the asked sum of multiples of five from 10 to 75, inclusive, is 595.
