How would you “find “x” in the diagram?
Answer: D
9514 1404 393
Explanation:
We have to assume the triangle is a right triangle.
In a 30°-60°-90° right triangle the side lengths have the ratio ...
short side : long side = 1 : √3
This lets you write the proportion ...
x/15 = 1/√3
Multiplying by 15 gives ...
x = 15/√3 . . . . . . matching choice D
__
There are other ways to get there. One of them is ...
x = 15·tan(30°) = 15/√3

really hard problem need help asap
Answer:
interior angle sum = (Number of sides x 180°) - 360°
interior angle sum = (6 x 180°) - 360° = 720°
∠CDE = (720° - 90° - 90°)/4 = 135°

Answer:
[tex] s = 4, \: q = 4 \sqrt{3} [/tex]
Step-by-step explanation:
In a 30°-60°-90° triangle, measure of side opposite to 30° angle is half of hypotenuse.
[tex]s = \frac{1}{2} \times 8 \\ \\ s = 8 [/tex]
In a 30°-60°-90° triangle, measure of side opposite to 60° angle is [tex] \frac{\sqrt 3}{2} [/tex] times of hypotenuse.
[tex] q = \frac{ \sqrt{3} }{2} \times 8 \\ \\ q = 4 \sqrt{3} [/tex]
Part of a cross-country skier's path can be described with the vector function r = <2 + 6t 2 cos(t), (15 − t)(1 sin(t))> for 0 ≤ t ≤ 15 minutes, with x and y measured in meters.
The derivatives of these functions are given by x′(t) = 6 − 2sin(t) and y′(t) = −15cos(t) + tcos(t) − 1 + sin(t).
Find the slope of the path at time t = 4. Show the computations that lead to your answer.
Find the time when the skier's horizontal position is x = 60.
Find the acceleration vector of the skier when the skier's horizontal position is x = 60.

The more often a lie is told, the more people will believe it. Many mathematical models for this psychological ploy exist
Answer:
hello your question is incomplete attached below is the complete question
answer : The vertical asymptote is not relevant since a negative population holds no relevance ( option 3 )
Step-by-step explanation:
attached below is the Graph of P(x) plotted using online tools as part of the solution requested by the question
From the attached graph vertical asymptote is x = 0
Also from the graph the x-intercept is (2, 0) which means that whenever a lie is told twice, Nobody believes the lie ( i.e. y = 0 when x = 2 )

7^2 = (2(6)^1/2)^2 + BC^2 (Pyth. theorem)
BC = 5
Answer:
its supposed to be 6.08 but we can take of..08 so 6
Step-by-step explanation:
[tex]a + b = c \\ ( 2 \sqrt{6} ) {}^{2} + {b}^{2} = {7}^{2} \\ 2 \times 6 + {b}^{2} = 49 \\ {b}^{2} = 49 - 12 \\ {b }^{2} = 37 \\ \sqrt{b} {}^{2} = \sqrt{37} \\ b = 6.08 \: or \: 6[/tex]
The difference between four times a number x and 5 is 24.
Answer:
4x - 5 = 24
x= 7.25
Step-by-step explanation:
4x - 5 = 24
4x= 24 + 5

Step-by-step explanation:
If CA= 4x and CB= 8x-12 , what is the length of CA ?
Answer:
Step-by-step explanation:
CA and CB are both opposite equal 90 degree angles so are equal so we can say
8x-12=4x
4x-12=0
4x=12
x=3, since CA=4x
CA=4(3)=12

What is the solution to the system of equations? y = x + 3 3x - 4y = -7
Answer:
x=-5 & y=-2
Step-by-step explanation:
Step 1: Solve y=x+3 for y:
y=x+3
Step 2: Substitute x+3 for y in 3x-4y =-7:
3x-4y=-7
3x-4(x+3)=-7
-x-12=-7 (Simplify both sides of the equation)
-x-12+12=-7+12 (Add 12 to both sides)
-x=5
-x/1=-5/-1 (Divide both sides by -1)
Step 3: Substitute -5 for x in y=x+3:
y=x+3
y=-5+3
y=-2 (Simplify both sides of the equation)
x=-5 and y=-2
what is the y-value of the solution to the system:{3x+4y=-6,5x+2y=4
Answer:
y = -3
Step-by-step explanation:
3x + 4y = -6 then, 3x = -4y - 6, x = (-4y - 6)/3
5x + 2y = 4
substitute for x:
5(-4y - 6)/3 + 2y = 4
simplify:
(-20y - 30)/3 = 4 - 2y
-20y - 30 = (3)(4 - 2y)
-20y - 30 = 12 - 6y
-14y = 42
y = -3
check:
5x + 2(-3) = 4
5x = 10
x = 2
3(2) + 4(-3) = -6
6 - 12 = -6
-6 = -6
5(2) + 2(-3) = 4
10 - 6 = 4
4 = 4

Artie
25%
Len
20%
Wen
30%
Gina
25%
Artie, Len, Gina, and Wen divided a carton of baseball cards as shown in the circle graph above. If Wen's
share was 60 cards, what was Gina's share of the cards?
25
50
100
200
Answer:
50
Step-by-step explanation:
Wen: 30% of the total number of cards = 60 cards
Set this up as an equation
30/100 = 60/x
Cross multiply
30 × x = 100 × 60
30x = 6000
Divide both sides by 30 to isolate the variable
x = 200
There are 200 cards total
Gina: 25% of the total 200 cards
Set this up as an equation
25/100 = x/200
Cross multiply
25 × 200 = 100 × x
5000 = 100x
Divide both sides by 100 to isolate the variable
50 = x
Gina's share is 50 cards
