A customer buys a book with an original selling price of $45. The book is discounted 15%. What is the cost of the book in dollars, the customer pays for the discounted price of the book
Given:
Original selling price of a book = $45
Discount Rate = 15%
To find:
The cost of the book in dollars, the customer pays for the discounted price of the book.
Solution:
We know that,
Discounted price = Original price - Discount
= Original price - 15% of original price
[tex]=45-\dfrac{15}{100}(45)[/tex]
[tex]=45-6.75[/tex]
[tex]=38.25[/tex]
Therefore, the discounted price of the book is $38.25. So, the cost of the book after discount is $38.25.

What single percentage change is equivalent to a 11% decrease followed by a 21% increase?
Answer:
7.69% increase
Step-by-step explanation:
Let our initial number be 100
11% decrease will be;
100- 0.11(100) = 100-11 = 89
A 21% increase will be;
89 + 21% of 89
89 + 0.21(89)
= 107.69
difference from the starting is 107.69 - 100 = 7.69
The percentage is 7.69% increase
A cuboidal soap dish has length 8 cm 5 cm and 13 cm find the volume of the research services placed on the top of the other
Answer:
520 cm³
Step-by-step explanation:
Volume of the cuboidal soap = length × width × height
Length = 8 cm
Width = 5 cm
Height = 13 cm
Volume of the cuboidal soap = length × width × height
= 8 cm × 5 cm × 13 cm
= 520 cm³

how to find out −7.1 + y = 3.5
Answer: 10.6
Step-by-step explanation:
-7.1 + y = 3.5
y = 3.5 + 7.1 [ -7.1 changes to 7.1 when transferred to RHS]
y= 10.6
Hope it helped u,
pls mark as the brainliest
^_^
-7.1 + y = 3.5
y - 7.1 = 3.5
y = 3.5 + 7.1
y = 10.6

5. Rationalize the denominator of the following: 2 root 6 divided by root 2 + root 3
Answer:
6 √2 -4 √3
Step-by-step explanation:
Here, we want to rationalize the denominator of the following surdic fraction;
2√6/(√2 + √3)
To rationalize this, we have to multiply the numerator and the denominator by the conjugate of the denominator
The conjugate of the denominator is √2 - √3
So, we have the rationalization as follows;
2 √6(√2-√3)/(√2 + √3)(√2-√3)
Thus, we have
(4√3-6 √2)/(-1)
= 6 √2 -4 √3

Round 10.95 to the nearest tenth
Hi there! To round 10.95 to the nearest tenth, we find the number in the tenth place, which is 9 and look one place to the right. Round up if the number is greater than 5 or equal to 5 and round down if its less than 5.
The answer is 11.0 or just 11.
Ed: Explanation below.
11.00
10.99
10.98
10.97
10.96
10.95 Look at the 9. Then look to the right. Do I round up or down?
10.94
10.93
10.92
10.91
10.90
If the number is greater or equal to 5, you round up. If the number is smaller than 5, you round down. 9 is greater than 5, so we round up.
Therefore, the answer is 11.
