x over 6 space equals space 10 over 12 ; x
Let's break this problem down in a few steps
x over 6 ⇒ x divided by 6 ⇒ [tex]\frac{x}{6}[/tex]10 over 12 ⇒ 10 divided by 12 = [tex]\frac{10}{12}=\frac{2*5}{2*6} =\frac{5}{6}[/tex]Since these two fractions are equal to each other, let's solve for x
[tex]\frac{x}{6}=\frac{5}{6} \\6x=30\\x = 5[/tex]
Thus x = 5
Hope that helps!
Answer:
[tex]x = 5[/tex]
Step-by-step explanation:
Step 1: Convert to an expression
x over 6 equals 10 over 12
[tex]\frac{x}{6}=\frac{10}{12}[/tex]
Step 2: Cross multiply
[tex](x * 12) = (6 * 10)[/tex]
[tex]12x = 60[/tex]
Step 3: Divide both sides by 12
[tex]\frac{12x}{12} = \frac{60}{12}[/tex]
[tex]x = 5[/tex]
Answer: [tex]x = 5[/tex]

find the value of x to the nearest tenth
Answer:
27
Step-by-step explanation:
So in the triangle, we've got the angle as 64°. And, there's only an opposite value and the hypotenuse value therefore the trig function is sin.
According to SOHCAHTOA,
sin=opp/ hyp
sin 64°=x / 30
Cross- multiply, then
x= 30 × sin 64°
x= 26.963
x= 27.0(nearest tenth)

Find the center and radius of the circle represented by the equation below.
(x + 5)² + (y – 5)² = 225
1
Center:
Radius:
Answer: the center is (-5, 5) and the radius is 15
Step-by-step explanation:
the standard form of a circle is
(x-h)^2 + (y-k)^2 = r ^2 where h is the x coordinate and k is the y coordinate of the center of the circle
(h,k) = the center of the circle
r = radius
therefore,
(x+5)^2 + (y-5)^2 = 225 means that x has to be -5 since subtracting a negative creates a positive and y must be 5 as it is negative in the equation
think of it as making the sum/difference 0 within the parentheses:
(x+5) -5+5 = 0 so x=-5
(y-5) 5-5 = 0 so y =5
so the center of the circle is (-5,5)
the radius is simply 225 square rooted which is 15
hope this helps :)

PLEASE HELP W BOTH PRECALC QUESTIONS!!!
Answer:
Step-by-step explanation:
Use the formulas supplied in the picture attached. There's nothing to really learn here, it is just a plug-and-chug formula:
[tex]sin(3x)sin(2x)=\frac{1}{2} [cos(3x-2x)-cos(3x+2x)][/tex]
[tex]sin(3x)sin(2x)=\frac{1}{2} [cos(x)-cos(5x)][/tex]
Moving on to the second problem:
[tex]cos(a)sin(b)=\frac{1}{2}[ sin(a+b)-sin(a-b)][/tex]
Therefore:
[tex]2cos(a)sin(b)=sin(a+b)-sin(a-b)[/tex]
Where:
[tex]a+b=5x[/tex]
[tex]a-b=3x[/tex]
Solve for 'a' using the second equation to get:
[tex]a=3x+b[/tex]
Plug this into the first equation to get:
[tex]3x+b+b=5x[/tex]
[tex]3x+2b=5x[/tex]
[tex]2b=2x[/tex]
[tex]b=x[/tex]
Therefore:
[tex]a+x=5x[/tex]
[tex]a=4x[/tex]
Finally:
[tex]sin(a+b)-sin(a-b)=2cos(4x)sin(x)[/tex]

What is a trapezoid?An open, flat object with four straight sides and one set of parallel sides is referred to as a trapezoid or trapezium. A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases.
Given that a shape is in trapezoid form.
The dimensions of the parallel sides are 4 and 6 units.
And a perpendicular side is 4 units.
The formula for the area of a trapezoid is:
Area = (1/2) × (sum of parallel sides) × (perpendicular distance between them)
In this case, the parallel sides have lengths 4 and 6 units, and the perpendicular distance between them is 4 units.
Substituting these values into the formula, we get:
Area = (1/2) × (4 + 6) × 4
Area = (1/2) × 10 × 4
Area = 20 square units
Therefore, the area of the trapezoid is 20 square units.

Ben has a dog that has a mass of 9 kilograms. What is the mass of the dog in grams?
Answer:
9000 grams
Step-by-step explanation:
Keep in mind the conversion 1 kilogram = 1000 grams, as 1 kilo means 1000.
⇒ 1 kilogram = 1000 grams
⇒ Ben's dog = 9 kilogram = x kilograms = 1000x grams
⇒ x = 9
⇒ Ben's dog = 9 kilogram = 1000x grams
= 1000(9) grams
= 9000 grams

Which inequality would result in the shaded solution on the unit circle to the right?
Explanation:
Cosine is positive in quadrants I and IV, but quadrant IV isn't shaded in so we can rule out choice A.
Sine is positive in quadrants I and II. So far it looks like choice B could work. In fact, it's the answer because sin(pi/6) = 1/2 and sin(5pi/6) = 1/2. So if 0 ≤ sin(x) < 1/2, then we'd shade the region between theta = 0 and theta = pi/6; as well as the region from theta = 5pi/6 to theta = pi.
Choice C is ruled out because tangent is positive in quadrants I and III, but quadrant III isn't shaded.
Choice D is ruled out for similar reasoning as choice A. Recall that [tex]\sec(x) = \frac{1}{\cos(x)}[/tex]
Answer:
0 ≤ sin x < 1/2.
Step-by-step explanation:
sin π6 = 1/2
sin 5π/6 = 1/2
sin 0 and sin 180 = 0
The dotted line indicates that the value of the sine is less than 1/2 and the solid line indicates that value is greater or equal to zero.
So the inequality is 0 ≤ sin x < 1/2
