I think of a number . If I subtract six from it and multiply the difference by 4 the result is 36. Evaluate the number that I thought of.
Answer:
15
Step-by-step explanation:
First we can make an equation by replacing the unknown number with x :
First step of problem:
x-6
Second part of problem:
4(x-6)
Third part of the problem:
4(x-6)=36
First we can expand the bracket to give us:
4x-24=36
Now we add 24 to both sides:
4x = 60
Now we divide both sides by 4 for our final answer of
x= 15
To check this answer we can put it back into the problem:
4(15-6)=36
4(9)=36
✅
Therefore our answer that was thought was 15.

Answer:
36 in²
Step-by-step explanation:
Area of the figure
Area (small rectangle) left + Area (big rectangle) right3 x (6 - 4) + 5 x 63 x 2 + 306 + 3036 in²Answer:
The answer is 36 ft²
Step-by-step explanation:
Let us divide this whole figure into 2 rectangle, a big and a small.
Rectangle 1: (Small)
Length (l) = 2 ftBreadth (b) = 3 ft(Area 1) = l × b
A = 2 × 3 = 6 square ft
Rectangle 2: (Big)
Length (l) = 6 ftBreadth (b) = 5 ft(Area 2) = l × b
A = 6 × 5 = 30 square ft
Now,
Total Area of figure = Area of Rectangle 1 + Area of Rectangle 2.
Total Area = 6 + 30 = 36 square ft.
Thus, The area of the figure is 36 ft².

2x squared + 13x - 24 =0
Answer: (2x - 3)(x + 8)
Step-by-step explanation:
2x² + 13x - 24 = 0, where is equal ax² + bx + c = 0 form. We get a = 2, b = 13, c = -24.
When a is not equal to 1, we multiply a and c. ac = 2(-24) = -48.
b in the equations means that the sum of two factor of ac is equal to 13. Then we need to find which two factor is add up to 13. In this case, we get -3 and 16.
2x² + 13x - 24 = 0
2x² + 16x - 3x - 24 = 0
2x(x + 8) - 3(x + 8) = 0
(2x - 3)(x + 8) = 0
Answer: x = -8, x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
This is a quadratic equation since it is in ax² + bx + c = 0 form! We will use the formula and use PEMDAS, the order of operations, while solving as well.
The quadradic formula, then plugging in to solve:
(please note before the square root is a ± sign. Brainly text editor will not allow me to add it)
[tex]x = \frac{-b\sqrt{b^{2} -4ac } }{2a}[/tex]
[tex]x = \frac{-13\sqrt{13^{2} -4(2)(-24) } }{2(2)}[/tex]
[tex]x = \frac{-13\sqrt{169 -4(2)(-24) } }{4}[/tex]
[tex]x = \frac{-13\sqrt{169 +192 } }{4}[/tex]
[tex]x = \frac{-13\sqrt{361 } }{4}[/tex]
Now it breaks into two parts:
[tex]x = \frac{-13-19}{4}[/tex] and [tex]x = \frac{-13+19}{4}[/tex]
[tex]x = \frac{-32 }{4}[/tex] [tex]x = \frac{6}{4}[/tex]
x = -8, x = [tex]\frac{3}{2}[/tex]
Solve for x. Please help and please show work, thanks!
Answer: 5
Step-by-step explanation:
We can use ratios / proportions to solve for x. I am going to have the shorter segment on the top of our fractions (the numerator), and the longer segments on the bottom (the denominator).
[tex]\frac{10}{10+12} =\frac{4x-5}{33}[/tex]
[tex]\frac{10}{22} =\frac{4x-5}{33}[/tex]
Now I am going to cross multiply:
10 * 33 = 22(4x - 5)
330 = 88x - 110
440 = 88x
5 = x
x = 5
Which of the following numbers CANNOT represent the probability of an event?
A. -0.5
B. 1
C. 0
D. 0.675
-0.5 cannot represent the probability of an event.
Correct option is (A).
What is Probability?This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Arithmetic uses probability to predict how probable certain events are to occur. Probability generally refers to the degree to which something is likely to occur.
As per the given data:
We have to find out that, which of the following numbers CANNOT represent the probability of an event.
Probability of an event = [tex]\frac{Favorable \: Events}{Total \: Number \: of \: Events}[/tex]
Favorable events or total number of events can never be negative, hence the probability of any event cannot be negative.
So from the above reasoning we can say that -0.5 cannot represent the probability of an event.
Hence, -0.5 cannot represent the probability of an event.

A. Reflect A over the line y=xC. Dilate A by 3/2How to prove that circle A and circle C are similar?The circles are given as:
Circle A and B
Assume the following parameters:
The center of circle A is (2,3) with a radius of 2The center of circle B is (3,2) with a radius of 3To start with;
The circle A must be reflected across the line y = x with the following transformation rule:
(x,y) -> (y,x)
So, we have:
(2,3) -> (3,2)
Next, the radius of A must be dilated by 3/2 as follows:
New Radius = 3/2 * 2 = 3
After the transformations, we have the following parameters:
The center of circle A is (3,2) with a radius of 3The center of circle B is (3,2) with a radius of 3Notice that both circles now have the same center and radius.

SOMEONE HELP PLEASE! I HATE ANGLES
Answer:
a = 51°
b = 67°
Step-by-step explanation:
Angle a is equal to 51 since it is vertically opposite to the angle on top of it.
Angles in a triangle add up to 180 so Angles a,b and 62 should add up to 180:
a+b+62=180
51+b+62=180
b= 180-(51+62)
b= 180-113
b= 67
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

The pilot of a small plane is flying at an altitude of 2000 ft- The pilor plans to start the final descent toward a runway when the horizontal distance between the plane and the runway is ? mi. To the nearest degree what will be the angle of depression 19 from the plane to the runw'y at this point?
Using the slope concept, supposing the horizontal distance is of 1500 feet, the angle of depression will be of 37º.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
In this problem, we suppose an horizontal distance of 1500 feet, with a vertical distance of 2000 feet, hence:
[tex]\tan{\alpha} = \frac{1500}{2000}[/tex]
[tex]\alpha = \tan^{-1}{\left(\frac{1500}{2000}\right)}[/tex]

Given the eqaution [tex]y=9^{5x}[/tex]
Lets solve for x.
Step 1.
Rewirte the equation as [tex]y=a^{bx}[/tex]. Where [tex]a=9[/tex] and [tex]b=5[/tex].
Step 2.
Take the natural logarithm of both sides. Then rewrite the left hand side using properties of exponents/logarithms.
[tex]ln(y)=b*x*ln(a)[/tex]
Step 3.
Divide both sides of the equation by [tex]b[/tex]
[tex]\frac{ln(y)}{b} =x*ln(a)[/tex]
Step 4.
Divide both sides of the equation by [tex]ln(a)[/tex]
[tex]\frac{ln(y)}{b*ln(a)} =x[/tex]
Now we have our equation to solve for the number of days.
Step 5.
Plug [tex]9[/tex] back in for [tex]a[/tex] and [tex]5[/tex] back in for [tex]b[/tex].

The cost to mail a package is $8 for the first 4 pounds and 25 cents for each additional ounce. Which of the following functions represents the cost to mail a package if x is the number of ounces over 4 pounds?
f( x) = 32 + 0.25 x
f( x) = 0.25( x + 4)
f( x) = 0.25+ 8 x
f( x) = 8 + 0.25 x
Answer:
f(x) = 8 + 0.25x
Step-by-step explanation:
The minimum cost is $8, for up to 4 pounds.
The added cost is ($0.25/oz)(x), where x is trhe ounces over 4 pounds
The total cost is the sum of these two:
f(x) = 8 + 0.25x
