Answer:
50
Step-by-step explanation:
<u>Definition of whole number: </u>Whole numbers are a set of numbers including the set of natural numbers (1 to infinity) and the integer '0'
The formula for finding the number of whole numbers between to given numbers “m” and “n” (assuming that “m” and “n” are included in the listing, and that “n” is the larger value) is:
(n - m) + 1
And the formula gives:
(79 - 30) + 1 = 49 + 1 = 50
Step-by-step explanation:
I think you mean you want to find out 40% of a number,, when 60% of it is 180, so I'll answer that:
60% = 180
÷6
10% = 30
x4
40% = 120
(if you want to find 100%, multiply 30 by 10)
Hopefully this helps :)
In order : Bracket power division multiplication addition subtraction
Means BODMAS
1. -10-60x
2. -16x+14
3. 42x-18
4. 24x-24
Why + and - are different
Remember this
- ( multiplies to) - = +
- (multiplies to ) + = - ( and vice versa)
Answer:
a. Geometric
b. 20, 10 and 5
c. Tn = 20(0.5)^n-1
d. 0.00004 ft
Step-by-step explanation:
a. The sequence is geometric
The reason for this is that we will be multiplying each term by a particular value
If it was arithmetic, we would have been adding instead. But since it is geometric, we shall multiply terms by a particular number
b. 1st term is
20
second term
1/2 * 20 = 10
Third term
1/2 * 10 = 5
c. Explicit formula
Mathematically, that will be;
Tn = ar^n-1
Where r is 1/2 or 0.5
Tn = a(0.5)^n-1
where Tn is the present term and n is the present number of the term
d. 20th term
T20 = 20 * 0.5^19
T20 = 0.00004 ft
Answer: A
Step-by-step explanation:
First route: 70 miles divided by 55 mph = 1.27 hours
Second route: 85 miles divided by 65 mph = 1.31 hours
The first route takes less time so it’s better
