Answer:
Sin31°= 11/x
x = 11/Sin31
x= 21.4. ( Nearest tenth).
Answer:
x ≈ 21.4
Step-by-step explanation:
Using the sine ratio in the right triangle
sin31° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{11}{x}[/tex] ( multiply both sides by x )
x × sin31° = 11 ( divide both sides by sin31° )
x = [tex]\frac{11}{sin31}[/tex] ≈ 21.4 ( to the nearest tenth )

If 2(x-y)=3y, what is the ratio x/y
Answers
Answer:
1 : 2.5
Step-by-step explanation:
Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).
2(x-y)=3y
divide both sides of the equation by 2
x - y = 3y/2
x - y = 1.5y
combine like terms together
x = 1.5y + y
x = 2.5y
ratio of x : y
1 : 2.5

9x + 4 + 113 = 180
9x + 117 = 180
9x + 117 - 117 = 180 - 117
9x = 63
9x ÷ 9 = 63 ÷ 9
x = 7
Answer:
9x + 4 + 180 + 113=360
9x + 297=360
9x=360-297
9x=63
9x÷9=63÷9

Write the word sentence as an inequality.
Then solve the inequality.
Five more than a number x is less than 17.
An inequality that represents this word sentence is x+5<17
The solution is ?
Answers
Answer:
x≤11
Step-by-step explanation:
x+5<17, I can subtract 5 on both sides so
x+5<17
-5 -5
x<12
that's wrong though because my x needs to make my answer less than x to make the statement true since we're looking for a value that is less than 17 not less than or equal to 17. So in conclusion, if x≤11 ( if x is less than or equal to 11), my statement will be true because 11+5<17=16<17, which is true. Even 10 or less is fine because it will still be smaller than 17 and that will keep my statement balanced.

Standard error of the mean: 1.91
Step-by-step explanation:
The standard error of a sample mean is [tex]SEM=\frac{\sigma}{\sqrt{n}}[/tex] where [tex]\sigma[/tex] is the sample standard deviation and [tex]n[/tex] is the sample size.

Each gridline represents one mile. If Ryan drove from home to the soccer field and then from the soccer field to the library, traveling in a straight line to each destination, he would have traveled ___ miles by the time he reached the library.
Answers
Answer:
13units
Step-by-step explanation:
Using the distance formula;
D = √(x2-x1)²+(y2-y1)²
Distance from home to the soccer field is expressed as;
Home (0,0) and soccer field (-4,3)
D =√(3-0)²+(-4-0)²
D =√3²+4²
D =√9+16
D = √25
D = 5
Distance from soccer field to library is expressed as;
Library (4,3) and soccer field (-4,3)
D =√(-4-4)²+(3-3)²
D =√(-8)²+0²
D =√64
D = 8
Hence the total distance = 5 + 8 = 13units

Required
60 degrees clockwise rotation about A
Since [tex]\triangle ABC[/tex] and [tex]\triangle ABD[/tex] are equilateral, then all angles in both triangles are [tex]60^o[/tex]
So, rotating in clockwise direction of A means that a line segment in the right of A will be considered.
The closest is line AC;
Hence, AC is [tex]60^o[/tex] clockwise of point A

Answers
Answer:
DE ≈ 16.1, ∠E ≈ 60.3°, ∠D ≈ 29.7°
Step-by-step explanation:
use pythagorean theorem:
DE² = 8² + 14² => DE = √8² + 14² ≈ 16.1
use inverse tangent function:
∠E = [tex]tan^{-1}[/tex](14/8) ≈ 60.3°
∠D = [tex]tan^{-1}[/tex](8/14) ≈ 29.7°
Answers:
side DE = 16.1 unitsangle E = 60.3 degreesangle D = 29.7 degreesThe "units" and "degrees" portions of the answers are likely to be left out.
===============================================
Explanation:
Since we have a right triangle, we can use the pythagorean theorem to find the hypotenuse DE
a^2+b^2 = c^2
c = sqrt(a^2+b^2)
c = sqrt(8^2+14^2)
c = 16.124515496597
c = 16.1 is the approximate length of side DE
----------------------------------
We'll use the tangent ratio to find angle E
tan(angle) = opposite/adjacent
tan(E) = FD/FE
tan(E) = 14/8
E = arctan(14/8)
E = 60.2551187030578
E = 60.3 degrees
The notation arctan is the same as inverse tangent. You should have a [tex]\tan^{-1}[/tex] button on your calculator to help compute the inverse tangent.
-------------------------------------
We could use the tangent ratio to solve for angle D, by noting that
tan(D) = 8/14
or we could use the idea that D+E = 90 which solves to D = 90-E
D = 90-E
D = 90-60.3
D = 29.7 degrees
Note how arctan(8/14) = 29.74488 which rounds to 29.7
