Answer:
115.2 total marks.
Step-by-step explanation:
If 72 is only 60% of the total marks, then to find the total number of marks we will need to multiply 72 by 60% to find the remaining marks, then add that back to 72.
72 × 0.6 = 43.2 remaining marks.
72 + 43.2 = 115.2 total marks.
The total number of marks in the test is 115.2 total marks.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We have been given that paul got 72 marks in a maths test. 72 marks is 60% of the total number of marks.
When 72 is only 60% of the total marks, then to find the total number of marks.
We will need to multiply 72 by 60% to find the remaining marks, then add that back to 72.
Then, 72 × 0.6 = 43.2 remaining marks.
72 + 43.2 = 115.2 total marks.
Hence, The total number of marks in the test is 115.2 total marks.

When you flip a baised coin the probability of getting tail is 0.75 How many times would you expect to get tails uf you flip the coin 320 times?
Answer: 60
How?: Well, we know that we have a 0.75 chance for tails. And on a coin, there is heads and tails. So, we multiply 0.75 (tails) by 320 and then divide that by 4. We do this because there is a 0.75 and 1 = 1.00. 1.00 - 0.75 = 0.25. 0.25 = 60

Decrease £740 by 8% .
Answer: 'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
8% = 8/100 = 8 ÷ 100 = 0.08.
100% = 100/100 = 100 ÷ 100 = 1.
Step-by-step explanation:
To calculate percentage decrease:
First: work out the difference (decrease) between the two numbers you are comparing. Then: divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number, then this is a percentage increase.
the sum of a number n and 3 is 9
Answer:
n is 6
Step-by-step explanation:
because sum means addition and if you subtract 9 by 3, you get 6, so we now know that the missing number is 6 because when you add 6 and 3, you get 9. :)
The statement in the mathematical form will be n + 3 = 9. And the value of the variable 'n' will be 6.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.
The sum of a number n and 3 is 9. Then the equation is given below.
n + 3 = 9
Simplify the equation, then we have
n + 3 = 9
n = 9 - 3
n = 6
The statement in the mathematical form will be n + 3 = 9. And the value of the variable 'n' will be 6.

f(1)= -34
f(n)=f(n−1) - 3
Find an explicit formula for f(n).
Answer:
f(n) = -34 -3(n - 1)
Step-by-step explanation:
The explicit formula for f(n) is given below:
Given that
f(1)= -34
f(n)=f(n−1) - 3
Based on the above information
f(n) = a1 +d(n -1)
a1 = -34
d = -3
So
f(n) = -34 -3(n - 1)
This above represent an explicit formula
