What value of x makes this proportion true? x/6=36/24 O A. 8 O B. 9 O C. 18 O D. 7
Answer:
B. 9
Step-by-step explanation:
Proportions are just like fractions and to figure them out sometimes you can use simplification in different forms.
[tex]\frac{x}{6}[/tex] = [tex]\frac{36}{24}[/tex]
Now to get to 6, 24 had to be divided by 4...in proportions and fractions usually, the top and bottom are both simplified or proportioned to the same number or scale
36 ÷ 4 = 9
Check your answer by inserting it there to see if it works
9*4 = 36 6*4 = 24
Answer:
[tex]\boxed {\boxed {\sf B. \ 9}}[/tex]
Step-by-step explanation:
We are given this proportion:
[tex]\frac {x}{6}=\frac{36}{24}[/tex]
We want to solve for x, so we must isolate the variable using inverse operations.
It is being divided by 6. The inverse of division is multiplication, so we multiply both sides of the proportion by 6.
[tex]6*\frac {x}{6}=\frac{36}{24}*6[/tex]
[tex]x=\frac{36}{24}*6[/tex]
[tex]x=1.5*6 \\x=9[/tex]
Another way to solve is with cross multiplication. Multiply the first numerator by the second denominator, then the first denominator by the second numerator.
[tex]\frac { x}{6}=\frac{36}{24}[/tex]
[tex]24*x=6*36[/tex]
[tex]24x=216[/tex]
The variable is being multiplied by 24. The inverse of multiplication is division, so we divide both sides of the equation by 24.
[tex]24x/24=216/24\\x=9[/tex]
The value of x that makes this proportion true is 9.

The seesaw moves and the angle created by the left side of the seating board and the central support is now 80 degrees. Create and use a model, to find the distance from point Q to the ground when the angle created by the left side of the seating board and the central support is 80 degrees. Show your work or explain your answer. Round your final answer to the nearest tenth of a foot. Enter your model, your answer, and your work or explanations in the space provided.
Answer:5.7
Step-by-step explanation:
The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The distance between the point Q and the ground is h-[L cos(80°)].
What is Tangent (Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The Base is the adjacent smaller side of the angle θ.
Let the height of the support be h and the height between the point q and the ground is x. Also, the distance between point Q and the support of the seesaw is L.
Now if we look at the ΔQAR, the measure of the ∠QRA is 80°, therefore, the sine of ∠QRA can be written as,
[tex]\rm Cos(\theta)=\dfrac{Base}{Perpendicular}\\\\Cos(\angle QRA) = \dfrac{AR}{QR}\\\\Cos(\angle QRA) = \dfrac{h-x}{L}\\\\L \times Cos(80^o)=h-x\\\\x=h-[L\ Cos(80^o)][/tex]
Hence, the distance between the point Q and the ground is h-[L cos(80°)].

HELP ME PLEASEEEEEEEEEEEE
Answer:
Step-by-step explanation:
There is really only one solution which is the third choice. When you are dealing with the equation in the form of y = mx + b, the b stands for the y-intercept. So, your y-intercept equals -1. When you are finding the x-intercept you can just substitute y for 0(the definition of x-intercept is where the graph crosses the x-axis, meaning y needs to be equal to 0) and you get that x equals 1/5.
The high school soccer team can have no more
than 22 players on the roster. Write and solve an
inequality finding the number of players the
coach may choose if the coach already has 13
players.
Answer:
13 + x ≤ 22
x ≤ 9
Step-by-step explanation:
Total players = 22
Players available = 13
Players remaining = x
The inequality can be written as:
Players available + Players remaining ≤ Total players
13 + x ≤ 22
x ≤ 22 - 13
x ≤ 9

Step-by-step explanation:
Answer: x = 35, angle 1 = 85, angle 2 = 70, angle 3 = 25
Step-by-step explanation:
Finding x: 85+2x+x-10=180
3x= 105
x= 35
x-10 = angle 3 due to a property of parallels lines so put x in to get that angle 3 is 25 degrees
angle 2x = 70 degrees
70 + 25+angle 1 = 180
angle 1 = 85
angle 2 = 180-85-25 = 70

2( 5/3 + 3/4 ) − 4/3
Answer: = 42/12 Or simply = 7/2
Step-by-step explanation:
2(5/3 + 3/4 ) − 4/3
= 2(5/3) + 2(3/4) − 4/3
= 10/3 + 6/4 - 4/3
= 6/3 + 6/4
= 24/12 + 18/12
= 42/12
