The local newspaper has letters to the editor from 50 people if this number represents 8% of all the newspaper readers how many readers does the newspaper have. I need help now I am taking a test please help me
Answer: 625
Step-by-step explanation:
Let x be the total number of readers have newspaper.
Given: 8% of x = 50
Since 8% = 0.08 [we divide percent by 100yo convert it in decimal ]
So, 0.08x =50
[tex]\Rightarrow\ x=\dfrac{50}{0.08}=\dfrac{5000}{8}[/tex]
[tex]\Rightarrow\ x= 625[/tex]
Hence, the total number of readers have newspaper = 625

Test 43,785 for divisibility by 2, 3, 5, 9, and 10.
3 and 5
5
3, 5, and 9
3 and 9
Answer:
Step-by-step explanation:
43,785 is not even so it is not divisible by 2
when we add its digits 4+3+7+8+5 = 27 and it is divisile by 3
43,785 ends with 5 so it is divisible by 5
43,785's sum of digits are 27 and it is divisible by 9
43,785 does not end with a zero so it is not divisible by 10

In a sale, normal prices are reduced by 35% The normal price of a bed is $1200 Work out the sale price of the bed.
Answer:
£780
Step-by-step explanation:
as its a decrease
we subtract 35 from 100 to get 65
we then divide 65 by 100
to get 0.65
then we do 0.65*1200
to get the answer of $780
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%. The sale price of the bed is $780.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the normal price of a bed is $1200. Therefore, the sale price of the bed is,
Sale Price = $1200 × (100% - 35%)
= $1200 × 65%
= $780

Step-by-step explanation:
We know that whole numbers:
are general counting numbers 0, 1, 2, 3, 4, 5, 6, … and so on.contains natural numbers that start from 1 onwards.contains positive integers along with 0.In general, the set of whole numbers is:
W = {0, 1, 2, 3, ...}
Thus, the set of whole numbers DOES NOT include negative integers and fractions.
Therefore, 0 is the only option that belongs to the set of Whole numbers.
David drove 236 miles in 4 hours. On average how fast did he drive, in miles per hour?
David drove 236 miles in 4 hours. On average he drives 59 miles per hour.
A key idea in mathematics is time speed and distance. Questions like circular motion, boats, and streams, mobility in a straight line, clocks, races, etc. frequently involve the concepts of time and distance. You can get a clear understanding of the Relationship Between Time Speed and Distance, Units, Conversions, etc. from this article. Find Formula for Time and Distance, Solved Examples that thoroughly demonstrate the subject.
How quickly or slowly an object move is all about the concept of speed in motion. Distance divided by time is the definition of speed. When a specific piece of information is known, the three variables of speed, distance, and time are given to solve for one of the three variables.
[tex]speed = \frac{distance}{time}[/tex]
According to the question, David drove 236 miles in = 4 hours
so, he can drive = [tex]\frac{236}{4}[/tex] miles in 1 hour
= 59 miles.
