A ladder rests 22 feet up the side of a building. If the base of the ladder is 20 feet away from the building, how tall is the ladder to the nearest hundredth?
Answer:
Length of ladder =L =15
Distance from wall = D =9
Height on wall = H =??
Pythagoras equation L*L = D*D + H*H
15×15= (9×9) + H×H
225-81 = 144 =HxH
H= 12 feet.

which is 1/3 - 1/6 in a fraction
Answer:
Step-by-step explanation:
1/3 - 1/6
2/6 -1/6= 1/6
find common denominator
For [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex] the fraction will be [tex]\dfrac{1}{6}[/tex] .
Given to us,
[tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]
To solve this, firstly we need to make the denominators the same, thus taking the LCM of both 3 and 6.
As we know the LCM of 3 and 6 is 6 itself.
So, multiplying and dividing by 2.
[tex]\dfrac{1}{3}\rightarrow \dfrac{1\times 2}{3\times 2}\rightarrow \dfrac{2}{6}[/tex]
Now,
[tex]\dfrac{2}{6}-\dfrac{1}{6} = \dfrac{1}{6}[/tex]
Hence, for [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex] the fraction will be [tex]\dfrac{1}{6}[/tex] .

Find the slope of the line that passes through (10, 92) and (97, -3).
Answer:
-95/87
Step-by-step explanation:
Formula to find slope: (y2-y1) / (x2-x1)
In this problem y2 is -3 and y1 is 92. x2 is 97 and x1 is 10.
We substitute these numbers into the equation.
(-3-92) / (97-10)
Then we simplify this by subtracting.
-95/87 is our final answer.

What single decimal multiplier would you use to decrease by 6% followed by a 7% increase?
Answer:
the single decimal multiplier is 1.0058
Step-by-step explanation:
Let us have 100
Decreasing by 6% will be
100 - 0.06(100)
= 94
Increasing by 7%
= 94 + 0.07(94)
= 100.58
So
to get the single decimal multiplier,
we have 100.58/100 = 1.0058

The probability of getting a 6 is 4/5. The dice is rolled 500 times How many sixes would you expect to roll
Answer: 400
Step-by-step explanation:
From the question, we are informed that the probability of getting a 6 is 4/5 and that the dice is rolled 500 times.
The number of sixes that would be expected to roll will be 4/5 multiplied by the number the dice is rolled
= 4/5 × 500
= 400
There'll be 400 sixes.

-79=7x+3(4x-1)
If you answer this then you are officially smart
Answer:

Step-by-step explanation:
-79 = 7x+12x-3
-79 = 19x-3
-19x = 76
x = -4
Answer:
x = -4
Step-by-step explanation:
7x + 3(4x) + 3(-1) = -79
7x + 12x - 3 = -79
19x - 3 = -79
19x = -76
x = -4

Which set of numbers describe the side length of a right triangle
Answer: 3,4,5
Step-by-step explanation:
5² = 3² + 4²
25 = 9 + 16
25 = 25
The set of numbers 3, 4, and 5 describe the side length of a right triangle.
Option C is the correct answer.
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
Set of numbers:
1, 2, 3
2, 3, 4
3, 4, 5
4, 5, 6
We need to find the set of numbers that describe the side length of a right triangle.
We will apply the Pythagorean theorem to all the sets of numbers.
Using 1,2,3.
1² = 2² + 3²
1 = 4 + 9
1 = 13
2² = 1² + 3²
4 = 1 + 9
4 = 10
3² = 1² + 2²
9 = 1 + 4
9 = 5
This is not true.
Similarly,
Set of numbers: 2,3,4 and 4,5,6 are not true.
Using 3, 4, 5
5² = 3² + 4²
25 = 9 + 16
25 = 25
This is true.
Thus,
The set of numbers 3, 4, and 5 describe the side length of a right triangle.
Option C is the correct answer.

Simplifying the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base we get [tex]\mathbf{3^3\:.\:2^2}[/tex]
Option D is correct answer.
Step-by-step explanation:
We need to simply the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base.
Solving:
[tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex]
We can write it as:
[tex]\frac{(3\:.\:2)^5}{3^2.2^3}[/tex]
Now using exponent rule: [tex](a\:.\:b)^m=a^m\:.\:b^n[/tex]
[tex]\frac{3^5\:.\:2^5}{3^2.2^3}[/tex]
Now using the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex] the bases should be same
[tex]3^{5-2}\:.\:2^{5-3}\\=3^3\:.\:2^2[/tex]
So, simplifying the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base we get [tex]\mathbf{3^3\:.\:2^2}[/tex]
Option D is correct answer.
