Answer:
The percentage difference between 3.4 and 3.42 is 0.58651% or 0.02.
Step-by-step explanation:
Find the absolute difference between two numbers: |20 - 30| = |-10| = 10
Find the average of those two numbers: (20 + 30) / 2 = 50 / 2 = 25
Divide the difference by the average: 10 / 25 = 0.4
Express it as percentages: 0.4 * 100 = 40%
in this case, it would be 3.4 and 3.42
Answer: 0.02
Step-by-step explanation: 3.42 is bigger than 3.4 and they are asking for the difference between the two measurements. So, you subtract the 3.4 from the 3.42

Which graphs have rotational symmetry? Check all of the boxes that apply.
On a coordinate plane, a cubic function has an x-intercept of (0, 0).
On a coordinate plane, an absolute value function opens down.
On a coordinate plane, an oval is in quadrant 1.
Answer:
The correct option are;
On a coordinate plane, a cubic function has an x-intercept of (0, 0)
On a coordinate plane, an oval is in quadrant 1
Step-by-step explanation:
Rotational symmetry of a shape is a shape that when it is rotated on its axis to a given angle less than one complete revolution, the shape looks exactly like the pre-image or original appearance of the shape
For a cubic function that has x-intercept = (0, 0) we have;
y = f(x) = a·x³ + b·x² + c·x
Has the shape f a fan blade and therefore, looks the sane when rotated when rotated through 180°
The shape of an oval looks the same when rotated through 180°
Answer:
This graph has rotational symmetry about the point
(0,0).
This graph has rotational symmetry about the point (2,4).

Write down 2 equivalent ratios to 3:5.
show the following numbers on number line 3/2, 5/2, -3/2
When you create the number line, put 0 in the middle. Basically you put all the numbers you got from least to greatest on the number.
Since -3/2 is less than 0, it will go to the left of 0.
Since 3/2 and 5/2 are greater than 0, it will go to the right of 0.
Remember to use sub points of 1.
Best of Luck!

Jane drew a point A located at (-2,-3) and point C located at (8,-3). What is the x-coordinate of point B that bisects? AC
Answer:
x-coordinates of point B = 3
Step-by-step explanation:
If the extreme ends of a segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], coordinates of the midpoint of the given segment will be = [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Coordinates of the extreme ends of segment AC are A(-2, -3) and C(8, -3).
Since B is a point that bisects the segment AC, coordinates of point B will be,
= [tex](\frac{-2+8}{2},\frac{-3-3}{2})[/tex]
= (3, -3)
Therefore, x-coordinates of the point B will be = 3

CAN SOMEONE PLEASE HELP ME FIND THE AREA OF A HEXAGON
Answer:
the answer is 57.12
Step-by-step explanation:
so the area of the rectangle is 74.24, thats where you get the 8 x 9.28, which is important. so next we're going to go is 9.28-5 which equals 4.28, and that is what the total bottom of 2 triangles would be, (if you drew a rectangle around it). the you would divide 4.28 by 2 to get 2.14, which is the value of 1. next you do 2.14 x 4 and get 8.56. then divide 8.56 by 2 and get back to 4.28. you take 4.28 and multiply it by 4 to get 17.12. from there on you do, 74.24 - 17.12 and get 57.12.

A ball will be drawn from a bag containing 20 balls numbered 1 through 20 . If each ball is equally likely to be drawn, what is the probability that the number on the ball drawn will be even or less than 5 ?
Answer:
7/10
Step-by-step explanation:
20 balls.
10 even, 10 odd.
4 numbers less than 5.
That is 14/20 --> 7/10
Most likely.
Probability that the number on the ball drawn will be even or less than 5
= 3/5
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Given,
Total no. of balls = 20
All balls are numbered with numbered 1 through 20.
Balls with even numbers or less than five:
1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20
No. of balls with even numbers and less than five = 12
Probability that the number on the ball drawn will be even or less than 5 = No. of balls with even numbers or less than five/Total balls
= 12/20
Probability = 3/5
Hence, 3/5 is the probability that the number on the ball drawn will be even or less than 5.

Step-by-step explanation:
start from f(g(x))
f(g(x))= 3(g(x)) -2
f(g(x))= 6x -2
h(f(g(x)))=(f(g(x)))² -5(f(g(x)))
h(f(g(x)))=(6x-2)² -5(6x-2)
h(f(g(x)))=36x²-24x+4-(30x-10)
h(f(g(x)))=36x²-24x+4-30x+10

1+tan²A
Answer:
See below
Step-by-step explanation:
[tex]A=\theta[/tex]
[tex]$\sin(90\º - \theta) \cos(90\º - \theta) = \frac{ \tan(\theta)}{1+ \tan^2(\theta)}$[/tex]
According to cofunctions identities:
[tex]\boxed{\sin(90\º - \theta)=\cos(\theta)}[/tex]
[tex]\boxed{\cos(90\º - \theta)=\sin(\theta)}[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{ \tan(\theta)}{1+ \tan^2(\theta)}$[/tex]
Once
[tex]$\tan(\theta)=\frac{\sin(\theta)}{\cos(\theta)} $[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{ \frac{\sin(\theta)}{\cos(\theta)}}{1+ \frac{\sin^2(\theta)}{\cos^2(\theta)}}$[/tex]
Take
[tex]$1+\frac{\sin^2(\theta)}{\cos^2(\theta)}}=\frac{\sin^2(\theta) + \cos^2(\theta)}{\cos^2(\theta)} $[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{ \frac{\sin(\theta)}{\cos(\theta)}}{\frac{\sin^2(\theta) + \cos^2(\theta)}{\cos^2(\theta)} }}$[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{\sin(\theta)}{\cos(\theta)} \cdot \frac{\cos^2(\theta)}{\sin^2(\theta) + \cos^2(\theta)} }$[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{\sin(\theta)}{\cos(\theta)} \cdot \frac{\cos^2(\theta)}{\sin^2(\theta) + \cos^2(\theta)} }$[/tex]
[tex]$\cos(\theta) \sin(\theta) = \frac{\sin(\theta)\cos(\theta)}{\sin^2(\theta) + \cos^2(\theta)} }$[/tex]

?/24 A refrigerator is priced at $525.50. There is a 7% sales tax rate. What is the sales tax for the refrigerator in dollars and cents? Round to the nearest penny
Answer: The sales tax is $36.79
Step-by-step explanation:
Multiply the sales tax percent by the money to find how much the sale tax is.
7% * 525.50 = 36.785 which rounds to 36.79 to the nearest penny.
The required amount of sales tax for the refrigerator is $36.785.
As mentioned in the question, a refrigerator is priced at $525.50. There is a 7% sales tax rate. The sales tax for the refrigerator in dollars and cents is to be determined.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
The total price of the sales tax = $525.50
Sales tax is 7%,
sales tax= 525.50 × 7%
sales tax = $36.785
Thus, the required amount of sales tax for the refrigerator is $36.785.

a retailer sold a shirt for rupees 1000 and he made a profit of 25% find the purchased price of a shirt
Answer:
750 rupees is used to make shirt
250 rupees is profit
Step-by-step explanation:
If the retailer sold the shirt for 1000 rupees and got 25% profit then that means 1/4 is profit and 3/4 is how much the retailer spent to make the shirt.
So 1000 times 3/4 is 750 which is how much the shirt really cost and
1000 times 1/4 is 250 and that is the retailers profit.
