Answer:
The answer would be 40!
Step-by-step explanation:
Estimating ~ rounding
I would round 24% (20%), and 289 (300).
using the formula:
= %/100,
I'm looking for "IS"
I multiply 20 (just 20, no percent) by 200 = 4000.
Then I divide by 100 to get the "IS".
That's how I got my answer!
Hope this helps!
Answer:
a) 1820 ways
b) 43680 ways
Step-by-step explanation:
When the order of the choices is relevant we use the permutation formula:
is the number of different permutations of x objects from a set of n elements, given by the following formula.
When the order of choices is not relevant we use the combination formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this problem, we have that:
(a) How many ways can this be done, if the order of the choices is not relevant?
(b) How many ways can this be done, if the order of the choices is relevant?
9*9=81
2*2=4
81-4=77
77 square feet.
Hope this helps :)
Answer:
Pranav had 36 posters on Monday.
Step-by-step explanation:
We can make up an equation to demonstrate this problem.
We don't know how many posters he had on Monday, so we can represent that amount as x. We know Pranav buys 10 more, so now it's x + 10. We also know that after he bought 10 more posters, half of all his posters got destroyed, leaving him with 23.
The final equation is:
(x + 10) ÷ 2 =23
We now need to isolate the x, so we multiply both sides by 2 to get rid of it.
It now equals:
x + 10 =46
Finally we subtract 10 from both sides.
Our answer is:
x =36
