How would I write 4 less than half a number is 12 as an equation?
Answer:
[tex]4 - \frac{1}{2}x = 12 [/tex]
I hope it helps
please mark me brainliest
Answer:
[tex]number = x \\ \frac{x}{2} - 4 = 12 \\ \frac{x}{2} = 12 + 4 = 16 \\ \frac{x}{2} = 16 \\ x = 16 \times 2 = 32[/tex]
Find the geometric probabilty of landing in the shaded area of the picture. The small circle has a diameter of 20 in and the larger circle has a diameter of 48 in. Round to the nearest hundredth place. Show and explain all work.
Answer:
0.17
Step-by-step explanation:
find the area of both circles:
small: 10^2 *pi=100pibig: 24^2 *pi=576pithen find the ration of the area of the small circle to the area of the large circle: 100pi/576pi (you can cancel out the pi here to get 100/576) -> 0.1736
round to the nearest hundredth and you get 0.17
Am marking the brainliest. Please help me solve this mathematics question.
Explanation:
Use the identity [tex]\sin{\theta} = 1 - \cos^2{\theta}[/tex] so we can write our equation as
[tex]6(1 - \cos^2{\theta}) - \cos{\theta} - 5 = 0[/tex]
or
[tex]6\cos^2{\theta} + \cos{\theta} - 1 = 0[/tex]
Let [tex]x = \cos{\theta}[/tex] so our equation becomes
[tex]6x^2 + x - 1 = 0[/tex]
Using the quadratic equation, we find that its roots are
[tex]x = \dfrac{-1 \pm \sqrt{(1)^2 - 4(6)(-1)}}{2(6)} = \dfrac{1}{3},\:-\dfrac{1}{2}[/tex]
which gives us
[tex]\cos{\theta} = \dfrac{1}{3} \Rightarrow \theta = 70.53°[/tex]
[tex]\cos{\theta} = -\dfrac{1}{2} \Rightarrow \theta = 120°[/tex]

When 3 is added to a number, and the result is multiplied by 5, you obtain two times the number
Hi
to solve you must transcrive every word in math terms correctly.
so let's first give a name to our mysterious number. As you know, in math we generally call unknown by letter. " X"
so let's now play the detective.
what do we know on " X" ?
we add 3 to X so we have : X+3
then we multiply by 5. so. ( X+3) *5 .
if we do that we have twice X , so 2X
so ( X+3) * 5 = 2 X
now that we have translatted our data in math term, let's unmask. " X"
( X+3) *5 = 2X
5*X +3*5 = 2X
5X +15 = 2X
5X-2X = -15
3X = -15
X = -15/3
X = -5
So is " -5" is our guy.
let's check it out to be sure .
-5 +3 = -2
-2*5 = -10
-10 is twice -5. so -5 is the correct answer.
Ps : some operation are commonly implied. if you do not. know how I could write some line in the calculus, dont hesitate to ask in comments.
There is no mysteries in math everything is done according to rules and can be explained. So don't hesitate !

Inequality
2x > 14
Solution
x > 7
Step-by-step explanation:
Twice of a number = 2x or 2 * x
Is more than 14 = > 14
Put these 2 descriptions together
2x > 14
Then divide each side by the coefficient
2x / 2 = x > 14 / 2 = x > 7
Answer:
2x > 14
Any number above 7.
Step-by-step explanation:
"Twice a number (x) is more than 14." can be written as 2x > 14.
Breakdown:
2x > 14 for Twice a number (x) is more than 14.
2x > 14 for Twice a number (x) is more than 14.
2x > 14 for Twice a number (x) is more than 14.
The solution to the inequality is any number above 7.

Which of the following angles DOES NOT have equal measure when a pair of parallel lines is crossed by a transversal?
Answer: we might have come across different types of lines such as parallel lines, perpendicular lines, intersecting lines, and so on. Apart from that, we have another line called transversal.
This can be observed when a road crosses two or more roads or a railway line crosses several other lines. These give a basic idea of a transversal. Transversals play an important role in establishing whether two or more other lines in the Euclidean plane are parallel.
In this article, you will learn the definition of transversal line, angles made by the transversal with parallel and non-parallel lines with an example.
SOOO in English its LM is the transversal made by the parallel lines PQ and RS such that:
The pair of corresponding angles that are represented with the same letters are equal.
If two parallel lines are cut by a transversal, each pair of alternate interior angles are equal. Transversal property 2

Answer:
225
Step-by-step explanation:
The sides of the small square is 5 m
There are 5 full shaded squares and 8 half squares
Shaded squares = fully shaded small squares + half squares
S = F + H
F = 5x5x5 = 125
H = 8/2 x 5² = 100
S = 100 + 125
S = 225

Answer:
61.4
Step-by-step explanation:
The length of two semicircles of diameter 10 is the circumference of a circle of that diameter:
C = πd = 10π ≈ 31.4
The perimeter includes that length plus the lengths of two straight sides that are 15 units each.
P = 31.4 + 2×15
P = 61.4 . . . . units

Ratios are used to show the relationships between 2 or more related variables.
The ratio that compare the quantities is: [tex]x : y = 5 : 2[/tex].See attachment for the modelLet

Find the slope that is PARALLEL and PERPENDICULAR to the equation of the line y = -1/2x+6.
Answer:
parallel: -1/2
perpendicular: 2
Step-by-step explanation:
lines that are parallel have the same slope because they never intersect
lines that perpendicular, have the opposite reciprocal slope.
y = mx + b
where m is the slope
y = -1/2x + 6
-1/2 is the slope.
the slope in the equation given: -1/2
the slope parallel to the line given : -1/2
the slope perpendicular : opposite reciprocal, so the opposite of -1/2 is 1/2 and the reciprocal of 1/2 is 2.
