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.

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

train station, rode on a train for 14 hours, and then took a bus.
How much time did Jerry spend riding on the bus?
Show your work.
Answer
hours
Answer:
What we know:
39 hours is the total amount of time spent on the trip.14 hours spent with both walking and the train.Our challenge:
To figure out how many __ hours were spent on the bus.Let's set up an equation,
-we'll assume that 'x' are the unknown hours spent on the bus.
The unknown hours spent on the bus plus the hours spent both on walking/and the train will equal a total of 39 hours.
So,
14 + x = 39
Solve for x;
-14 -14
x = 25, the hours Jerry spent riding on the bus is 25 hours.
Answer:
25 hours
Step-by-step explanation:
Given
It took 39 hours in total to get to his grandmother's houseWalking and train transit takes 14 hours togetherSolving
Total time = Time (walking) + Time (train) + Time (bus)39 hours = 14 hours + Time (bus)Time (bus) = 39 - 14 = 25 hoursJanyah is expected to receive a 4% raise after her yearly evaluation? Her current pay is $14.25 per hour. Calculate her new annual pay?

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].
[tex]\frac{ln(y)}{5*ln(9)} =x[/tex]
Step 6.
We are given 243 million for [tex]y[/tex].
Lets plug in 243 million.
[tex]\frac{ln(243,000,000)}{5*ln(9)} =x[/tex]
Step 7.
Solve for x.
[tex]x=1.7575419...[/tex]
Lets round to the hundreth's place.

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.

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

What is special about the triangle that forms the yield sign ?
Answer:
Step-by-step explanation:
Just as the “stop sign” uses its 8 sides to communicate about “sharing the stop in all directions”, the yield sign’s 3 sides communicate as well. That triangle communicates that things’ll get tighter and tighter for you, as you move up. It’s sort of implicit - your space is going away. You need to stop and yield to others whose space hasn’t gone away.

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
Find the length of the segment indicated. Round your answer to the nearest tenth. Please and thank you so very much!!!
Answer:
14.7
Step-by-step explanation:
The given horizontal line is in the center of the circle (indicated by the black dot in the middle), so you can divide 17.5 by 2 in order to find the length of the leftmost segment of the triangle (8.75).
To solve for x, we use the pythagorean theorem as this is a right triangle:
[tex]a^{2} + b^{2} = c^{2}[/tex]
[tex]11.8^{2} + 8.75^{2} = x^{2}\\139.24 + 76.5625 = x^{2}\\215.8025 = x^{2}\\x = 14.6902178...[/tex]
This is 14.7 when rounded to the nearest tenth

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.
Hence, both circles are similar

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.
