Determine the missing length of the right triangle below using the Pythagorean Theorem (a²+b²=c²). Round to the nearest whole number.
Answer:
11
Step-by-step explanation:
[tex]c=\sqrt{a^{2} + b^{2} } \\14 = \sqrt{9^{2}+ b^{2} } \\14 = \sqrt{81 + b^{2} } \\14^{2} = 81+b^{2} \\196 = 81 + b^{2} \\81 + b^{2} = 196\\b^{2} = 196-81\\b^{2} = 115\\b = \sqrt{115} \\b = 10.72\\b = 11[/tex]

If a figure is dilated by a factor of 5/6 Area of a figure will change by a factor of
Given:
A figure is dilated by a factor of [tex]\dfrac{5}{6}[/tex].
To find:
The factor by which the area of the figure will change.
Solution:
We know that, if a figure is dilated by a factor k then the area of that figure is change by a factor of k² .
A figure is dilated by a factor of [tex]\dfrac{5}{6}[/tex].
So, [tex]k=\dfrac{5}{6}[/tex].
The area of the figure will change by a factor of k² .
[tex]k^2=\left(\dfrac{5}{6}\right)^2[/tex].
[tex]k^2=\dfrac{5^2}{6^2}[/tex]
[tex]k^2=\dfrac{25}{36}[/tex]
Therefore, the area of the figure will change by the factor of [tex]\dfrac{25}{36}[/tex].

Three consecutive even numbers are such that the sum of four times the smallest and twice the largest exceeds three times the second by 2006. What is the sum of the digits of the smallest number
Answer:
the sum of the digits of the smallest number 668 = 6+6+8 = 20
Step-by-step explanation:
3 consecutive even number: x, x+2, x+4
4x + 2*(x+4) = 3*(x+2) + 2006
6x + 8 = 3x + 6 + 2006 = 3x + 2012
6x - 3x = 2012 - 8 = 2004
3x = 2004
x = 668
the sum of the digits of the smallest number = 6+6+8 = 20
The residents of a city voted on weather to raise property takes. The ratio of yes votes to no votes was 7 to 5. If there were 2885 no votes, what was the total number of votes
Answer: 6,924 votes
Step-by-step explanation:
The ratio of yes to no votes was 7 to 5.
This means that for every 7 yes votes, there were 5 no votes.
If there were 2,885 nos, the number of yeses can be gotten using direct proportion:
7 : 5
x : 2,885
Cross multiplying would give:
5x = 20,195
x = 20,195/5
x = 4,039 yes
Total votes would be:
= 4,039 + 2,885
= 6,924 votes

Simplify 2x(x - 6) using either Algebra tiles or the Box Method on a sheet of paper.
Answer:
[tex]2x^2-12x[/tex]
Step-by-step explanation:
Given data
We are given the expression
2x(x - 6)
we can re-write it as
=2x*(x - 6)
let us open the bracket
=[tex]2x^2-12x[/tex]
Hence the simplified form is
[tex]2x^2-12x[/tex]
please help :/ it’s pythagorean theorem
Answer:
10.9ft13.7ftStep-by-step explanation:
The formula for Pythagorean theorem is [ a² + b² = c² ]. We are already given "a" and "c" for both problems, so, solve the theorem for b.
Question 1:
5² + b² = 12²
25 + b² = 144
b² = 119
√b = √119
b ≈ 10.9ft
Question 2:
6² + b² = 15²
36 + b² = 225
b² = 189
√b = √189
b = 13.7ft
Best of Luck!
Find the unknown sides and angles of this triangle using the Law of Cosines. Round to the nearest hundredth.
Answer:
Side c = 10.35
Angle A = 50.87°
Angle B = 94.13°
Step-by-step explanation:
The Law of Cosines states that:
a² = b² + c² - 2bcCos A
We are to to find side c, Angle A and B
side a = 14
sides b = 18
Angle C = 35°
1) Side c
= c² = a² + b² - 2abCos C
c² = 14² + 18² - 2 × 14 × 18 Cos 35
c = √(14² + 18² - 2 × 14 × 18 Cos 35)
c = 10.3512
Approximately = 10.35
2) Angle A
Cos A = b² + c² - a²/2bc
A = arc cos (b² + c² - a²/2bc)
A = arc cos (18² + 10.35² - 14²/2 × 18 × 10.35)
A = 50.8737°
A = Approximately = 50.87°
3) Angle B
Cos B = a² + c² - b²/2ac
B = arc cos (a² + c² - b²/2ac)
B = arc cos (14² + 10.35² - 18²/2 × 14× 10.35)
A = 94.13123°
A = Approximately = 94.13°

Ryan put $160 in a bank account. After 2 months, the total in his account decreased by 25%. What is the amount in Ryan's account now?
Answer:
$140
Step-by-step explanation:
Ryan put $160 in a bank account. After 2 months, the total in his account decreased by 25%.
Step 1
We calculate the Decrease
Original amount × Percentage Decrease
Original amount = $160
Percentage Decrease = 25%
Hence:
Decrease = $160 × 25%
= $40
Step 2
The amount in Ryan's account now is calculated as:
$160 - $40
= $140

how do you put these numbers onto a graph
9514 1404 393
Answer:
use a spreadsheet or graphing calculator
Step-by-step explanation:
First of all, you need to understand what it is you're graphing.
The given expressions are nonsense, as it is quite clear, for example, that 0=200 is a false statement.
Perhaps you're intending to graph ordered pairs, such as (0, 200) or (2, 241.1208).
You can enter these numbers with their 7-significant-figure precision into your calculator or spreadsheet, but nobody will be able to read more than about 3 (at most, 4) significant digits from any resulting graph.
Graphed as ordered pairs of the sort shown above, the graph will look something like the one attached.
How do you know when a mapping diagram, ordered pair, table or graph is a function
Answer:
To check if a relation is a function, given a mapping diagram of the relation, use the following criterion: If each input has only one line connected to it, then the outputs are a function of the inputs.

Write an equation in point-slope form of the line having the given slope that contains the given point. then graph the line
(dont think u can graph so its okay)
Answer:
The line of the equation in the point-slope form of the line passing through the point (3, -1) and having slope 1/2 will be:
[tex]y +1 = \frac{1}{2} (x-3)[/tex]
Please check the attached graph.
Step-by-step explanation:
Given
The slope m = 1/2The point (3, -1)Point slope form:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case:
m = 1/2
The point (x₁, y₁) = (3, -1)
substituting the values m = 1/2 and the point (x₁, y₁) = (3, -1) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - (-1) = \frac{1}{2} (x-3)[/tex]
[tex]y +1 = \frac{1}{2} (x-3)[/tex]
Thus, the line of the equation in the point-slope form of the line passing through the point (3, -1) and having slope 1/2 will be:
[tex]y +1 = \frac{1}{2} (x-3)[/tex]
Please check the attached graph.
