(-87-12÷3×4) + (37-29) ×4
Answer:
103
Explanation:
Follow BODMAS
BODMAS stands for bracket of division multiplication addition and subtraction.
( 87 - 12 / 3 * 4 ) + ( 37 - 29 ) * 4
( 87 - 4 * 4 ) + ( 8 ) * 4
( 87 - 16 ) + 32
71 + 32
==> 103
use the following list to find the average or mean, the median, the mode, and the range 10, 15, 5, 8, 6, 6, 2
Answer:
Mean - 7.43
Median - 6
Mode - 8
Range - 13
Step-by-step explanation:
To find the mean/average, add up all the numbers and divide the sum by the # of data points. (ex. you have 7 numbers, so you divide the sum of the numbers by 7.)
The median of a set of data is the middle number of ascending numbers in the data. If there was an even number of data points you would have to add the 2 middle numbers and divide by 2.
The mode is the number that appears most frequently in the data set.
To find the range, just subtract the lowest number in the data set from the greatest number.
Answer:
mean= 7.4, median = 6, mode =6, range = 13
Step-by-step explanation:
mean = 10 + 15 + 5 + 8 + 6 + 6 + 2 ÷ 7
= 52 ÷ 7
= 7.4
median= 2, 5, 6, 6, 8, 10 , 15
6
median is the middle number from ascending order
mode = 6
mode is the number that occurs the most
range = 15 - 2
13
range is the different between the largest and smallest number

A trader sold 250 articles for $525,000.00 at a profit of 25%.
a.Calculate the cost of each article.
b.If the trader had wanted 45% profit on the cost price then how much would he sell the articles?
Answer:
a. $2100 b. $945000
Step-by-step explanation:
You have to divide 525000 and 250 to solve for "a". To solve for "b" you need to find %100 of the profit and do %100 of the profit times 0.45 to see how much is %45 of profit.

The profitability, P, of a popular restaurant franchise can be modeled by the function P (t) = t4 – 9t3 + 24t2 – 20t, where t is the number of months since the restaurant opened. How many months after the franchise opens will it begin to show a profit?
5 months
3 months
2 months
1 month
Replace t with the months given as choices to see which one gives a positive value as an answer.
P(1) = 1^4-9(1)^3 + 24(1)^2-20(1) = -4
P(2) = 2^4-9(2)^3+24(2)^2-20(2) = 0
P(3) = 3^4 -9(3)^3+24(3)^2-20(3) = -6
P(5) = 5^4-9(5)^3+24(5)^2-20(5) = 0
P(6) = 6^4-9(6)^3+24(6)^2-20(6) = 96
It shows a profit in month 6 so it would start showing a profit in month 5.
The answer is 5 months
y-3 = 2(x+1)
fiind the missing value ?
Step by step process:
Let's solve for x.
y−3=2(x+1)
Step 1: Flip the equation.
2x+2=y−3
Step 2: Add -2 to both sides.
2x+2+−2=y−3+−2
2x=y−5
Step 3: Divide both sides by 2.
2x/2=y−5/2
x=1/2y+(−5/2)
Answer: x=1/2y+(−5/2)
Let's solve for y.
y−3=2(x+1)
Step 1: Add 3 to both sides.
y−3+3=2x+2+3
y=2x+5
Answer:
y=2x+5

If x = 2y then, 5y - x in terms of y is equal to 3y and when y = 2, the value of 5y - x is 6.
To solve 5y - x in terms of y, we need to substitute the value of x in terms of y. Given that x = 2y, we can replace x with 2y in the expression 5y - x:
5y - x = 5y - (2y)
Now we simplify the expression by subtracting 2y from 5y:
5y - (2y) = 3y
Therefore, 5y - x in terms of y is equal to 3y.
To find the value of the expression when y = 2, we substitute y = 2 into the expression:
3y = 3 * 2 = 6
Thus, when y = 2, the value of 5y - x is 6.

Please help: is the square root of -9 a whole number, integer, rational., or irrational?
Answer:
Step-by-step explanation:
None of the above.
It is a complex number. The sqrt(-9) is defined as 3i.
i is a definition brought into existence to represent the square root of -1. There is nothing at this level of math that you can point to and say this is the physical thing that is the square root (-1). It is just a math/physics definition.
