What is BODMAS rule?BODMAS rule is a rule of calculating expressions which include more than one different mathematical operations.
BODMAS is an abbreviation for Brackets, Orders, Division, Multiplication, Addition and Subtraction.
So while calculating expressions including different operations, we should follow this order.
Here, the given expression is 6 + 5 . (8 ÷ 2) 2.
By BODMAS rule, we should calculate the expression in the bracket first.
8 ÷ 2 = 4
So, the expression becomes 6 + 5 × 4 × 2.
There are two operations, multiplication and addition here.
We should go for multiplication first.
5 × 4 × 2 = 40
The expression becomes 6 + 40 = 46.
Hence we got the value of the expression 6 + 5 . (8 ÷ 2) 2 as 46.

a small college had 2570 students in 1994 and 2734 students in 1996. if the enrollment follows a linear growth pattern, how many students should the college have in 2004 ?
Answer: The final answer is 3390.
Step-by-step explanation:
Before answering the question, you have to understand that a linear growth pattern is a straight-line pattern (not exponential growth).
-From 1994 to 1996 are 2 [years]
-In 2 [years], there is a growth of 2734-2570 = 164 [students]
-With a linear growth, we can take the above [number of students] (164) divided by 2 [years] to get a [growth rate] of 82 [students per year]
⇒ [tex]\frac{164}{2} =82[/tex] [[tex]\frac{number of students}{years}[/tex] or number of students per year or growth rate]
-From 1996 to 2004, there are 8 [years]
-Therefore:
8 [years] × 82 [students per years] = 656 [students] => increased in students
-We add 656 [students] increased to 2734 [students] in 1996 = 3390 [students] in 2004
The final answer is 3390.

At Acme Inc., there are 3 more than twice as many salespeople as inventors. If the whole company has 27 employees,
how many inventors are there?
Answer:
There are 8 inventors.
Step-by-step explanation:
Let 's' be the salespersonLet 'i' be the inventorsGiven that there are 3 more than twice as many salespeople as inventors.
i.e s = 3+2iAlso given that the whole company has 27 employees.
i.e.
s + i = 27
substituting s = 3+2i
3 + 2i + i= 27
3 + 3i = 27
3i = 27 - 3
3i = 24
divide both sides by 3
i = 8
Thus, there are 8 inventors.VERIFICATION
As the total number of employees is 27.
so the salespeople will be:
s = 3+2i
= 3 + 2(8)
= 3 + 16
= 19
Thus, the total employees are verified as:
s + i = 27
19 + 8 = 27
27 = 27

Answer:
x = 17
<2 = 121
Step-by-step explanation:
We know that angle 1 and angle 3 form a linear pair, which means they add to 180
7x+2 + 3x+8 = 180
Combine like terms
10x+ 10 = 180
Subtract 10 from each side
10x+10-10 = 180-10
10x = 170
Divide by 10
10x/10 =170/10
x = 17
Angle 1 and angle 2 are vertical angles and vertical angles are equal
<1 = <2 = 7x+2 = 7(17) +2 =119+2=121
Find the value of 4x-4 given that - 3x +7=4.

To manufacture scooters, the manufacturer has a fixed cost of 34,400$$ plus a variable cost of n $$ per scooter. Find 100$$, the number of scooters that need to be produced so that the average cost per scooter is 180$$.
Answer:
The number of scooters that need to be produced so that the average cost per scooter is $180 is 430 scooters.
Step-by-step explanation:
Note: This question is not properly structured/written. The question is therefore rewritten properly before answering the question as follows:
To manufacture scooters, the manufacturer has a fixed cost of $34,400 plus a variable cost of $100 per scooter. Find n, the number of scooters, that need to be produced so that the average cost per scooter is $180.
The explanation of the answer is now provided as follows:
The number of scooters can be calculated as follows:
Variable cost per scooter = $100
n = number of scooter = ?
Total variable cost = Variable cost per scooter * n = $100 * n = $100n
Total cost = Fixed cost + Total variable cost = $34,400 + $100n
Average cost per scooter = Total cost / n = $180 ................ (1)
Substituting the value for Total cost into equation (1) and solve for n, we have:
($34,400 + $100n) / n = $180
$34,400 + $100n = $180n
$34,400 = $180n - $100n
$34,400 = $80n
n = $34,400 / $80
n = 430
Therefore, the number of scooters that need to be produced so that the average cost per scooter is $180 is 430 scooters.
Leah scored 13 points the first half of the basketball game, and she scored x points in the second half of the game. Write an expression to determine the number of points she scored in all. Then, find the number of points she scored in all if she scored 3 points in the second half of the game.
Answer: Expression: 13+x
Answer if she scored 3 in the second half=16
Step-by-step explanation:
Since she scored 13 points in the first half and X amount in the second, it's asking for the total number. Since X is unknown, it's simply 13+x. Then, they say X=3. Now plug 3 in for X and solve.
ie: 13+3

hello im ganna do fraccions what is 13\15 + 8\3 + 2\9 =
Answer:
3 34/45
Step-by-step explanation:
The common denominator of these is 45.
13/15 = 39/45
8/3 = 120/45
2/9 = 10/45
Add that up and that is 169/45
Simplify as a mixed number, and it would be 3 34/45
Answer:
169/45
Step-by-step explanation:
First lets do 13/15 + 8/3.
We can multiply 8/3 by 5 to both num and denom for a ration, with the denominator being 15: 40/15.
Then add 13/15 to 40/15 to get 53/15
Now multiply that by 3 to both num and denom to get 159/45. This is to get the least common factor with 9.
2/9 can be multiplied by 5 to both num and denom to get the least common factor with 15: 10/45
Now add 159/45 with 10/45 = 169/45
169/45 is the least it can be simplified so that is the answer.

Colbalt-60 has half-life of about 5 years, How many grams of a 300 g sample will remain after 20 years?
Answer:
After 20 years 18.75 gm of sample will remain.
Step-by-step explanation:
The half-life is the time it takes for any amount of Cobalt-60 to decay to half the starting amount.
20 years is 4 times the half-life of 5 years. So there would be
(300 g) / 2⁴ = 18.75 g
remaining after 20 years.
In other words, after 5 years, 300 g decays to 150 g.
After another 5 years (total 10 years), 150 g decays to 75 g.
After another 5 years (total 15 years), 75 g decays to 37.5 g.
After another 5 years (total 20 years), 37.5 g decays to 18.75 g.

A driver drives to school along the same routine Monday through Friday. There is one traffic light on her route . The probability that the light will be red is 65% . What is the probability that she will not have to stop at the light all next week?
Answer:
0.525%
Step-by-step explanation:
Since we are trying to find the probability of a sequence of events we simply need to multiply the probability of each of these events happening separately from one another. We are told that the probability that the light will be red is 65% that means that the probability that it will be green and that the driver will not need to stop is 35%. This probability remains the same every day of the week. Therefore we need to multiply this probability 5 times, one time for each weekday Monday through Friday, but first we need to turn this percentage into a decimal form by dividing it by 100...
35% / 100 = 0.35
0.35 * 0.35 * 0.35 * 0.35 * 0.35 = 0.00525 ...multiply by 100 to get percentage
0.00525 * 100 = 0.525%
Finally, we can see that the probability that she will not have to stop at the light all next week is 0.525%
