The reason we multiply x by 100 is because 0.1515... has 2 repeating digits and 100 has two zeros.
I hope this helps! A brainliest would be much appreciated :)
The equivalent fraction for the given repeating decimal is 15/99.
The given decimal is 0.1515.....
We need to represent the given repeating decimal to an equivalent fraction.
How to convert a repeating decimal to a fraction?The repeating decimal to fraction steps of conversion are given below:
Step 1: Identify the repeating digits in the given decimal number.
Step 2: Equate the decimal number with x or any other variable.
Step 3: Place the repeating digits to the left of the decimal point by multiplying the equation obtained in step 2 by a power of 10 equal to the number of repeating digits. This way you will get another equation.
Step 4: Subtract the equation obtained in step 2 from the equation obtained in step 3.
Step 5: Simplify to get the answer.
Now, in the given repeating decimal 2 digits are repeating.
Take, n=0.1515....--------(1)
Multiply both sides of equation (1) by 100.
That is, 100n=15.1515.......(2)
Now, subtract equation (1) from equation (2).
That is, 100n-n=15.1515......-0.1515......
⇒99n=15
⇒n=15/99
Therefore, the equivalent fraction for the given repeating decimal is 15/99.

What is the interquartile range of this data?
6

9
Answers
Step 1: Find Q2
Note - Q2 is basically the median of the set
We see that the two numbers in the middle are 28 and 32.
To get the median, find the average of 28 and 32.
28 + 32 = 60, 60/2 = 30
Q2 = 30
Step 2: Find Q1
The median splits the set. So anything before 30, is what we should focus on.
In this case, it's: 12, 16, 20, 24, and 28
Find the median of those five numbers. We get: 20
Q1 = 20
Step 3: Find Q3
Similar to before, focus on the numbers after 30.
In this case, it's: 32, 36, 40, 44, 48
Find the median of those five numbers. We get: 40
Q3 = 40
Step 4: Find the IQR
The IQR (Interquartile Range), as shown in its name, is found by subtracting Q3 and Q1.
Q3 - Q1 = 40 - 20 =20
IQR = 20

If you divided 26 objects into sets of 6, how many sets of 6 could you make, and how many are left over?
Options:
A. 2 sets with 4 left over
B. 4 sets with 2 left over
C. 3 sets with 3 left over
Answers
Answer:
B. 4 sets with 2 left over
Step-by-step explanation:
We have to find out how many times 6 can go into 26. We know that 6 times 4 is equal to 24, so we know that 6 can go into 26, 4 times.
Now we have to figure out how many are left over. To do that, lets subtract 26 minus 24, which equals 2.
Therefore, the answer is B, 4 sets with 2 left over.

1222
Reason for this answer:
The surface area of given figure is 1222 [tex]ft^{2}[/tex]
What is Surface Area ?Surface area is the amount of space covering the outside of a three-dimensional shape.
Firstly, Take the cuboidal base.
We will find the area of the front and back face which is shape of rectangle.
The side faces of rectangles and lastly the bottom face.
Area of Front and back face= area of 2 rectangles= 2 x length x breadth
= 2 x 19 x 11
= 418 [tex]ft^{2}[/tex]
Area of side faces = area of 2 rectangles= 2 x side x side
= 2 x 11 x 9
=198 [tex]ft^{2}[/tex]
Area of bottom = Length x breadth= 19 x 9
= 171 [tex]ft^{2}[/tex]
Now, area of faces remaining on the side of the triangular prism.
There are two rectangle of measurement : length= 9 ft and breadth = 4.5 ft
Area of two remaining faces on top other than triangular base= l x b= 2 x (9 x4.5)
= 81 [tex]ft^{2}[/tex]
At last, the side faces of triangular prism whose area be,=2 x 13 x 9
= 234 [tex]ft^{2}[/tex]
Area of front and back face of triangular prism= 2 x ( [tex]\frac{1}{2}[/tex] x b x h )
= 2 x 0.5 x 10 x 12
= 120[tex]ft^{2}[/tex]
Total Surface Area of the figure is,= 418+ 198+171+234+81+120
= 1222 [tex]ft^{2}[/tex]

Jermaine had dinner at his favorite restaurant. If the sales tax rate is 5% and the sales tax on the meal came to $2.00, what was the total cost of the meal, including sales tax and a 15% tip?
A) $52.50
B) $40.00
C) $48.00
D) $57.00
Answers
Answer:
B
Step-by-step explanation:
I did 15+5 and got 20 and 20 x 2 = 40 so the answer is B
Let x be the cost of the meal as
x*0.05=$2.00
So,
x=$2.00/0.05
x=$40.00
So the cost of meal is $40.00
The tip is 15% or 0.15
Let y be the tip as
y=$40.00*0.15
y=6
So $40+$6=$46
