Answer:
x = 25
Step-by-step explanation:
Given:
Amount invest p = Tk.x
Number of year t = 4
Rate r = x%
Profit = Tk.x
Find:
Value of x
Computation:
Profit = prt / 100
Tk.x = [(Tk.x)(x)(4)] / 100
x = 100 / 4
x = 25
The symbol ∩ in math means that two equations are combined to create a general statement.
The first answer indicates that x + 1 is less than -1, and less than 1. Any number less than -1 will fit both criteria.
The second answer indicates that x + 1 is less than or equal to 1, and greater than or equal to 1. There is one solution, as x = 0 will give an output of 1, which fits both criteria.
The third answer indicates that x + 1 is less than 1, and greater than 1. There is no possible value of x that would fit both criteria, as it is impossible for one number to fit both criteria.
The answer is (x + 1 < 1) ∩ (x + 1 > 1).
Answer:
c 7
Step-by-step explanation:
5a^3 + 9a^2 +7a+4
The coefficient of a is the number in front of a
Answer:
3
Step-by-step explanation:
C(n) = 5n, 0 ≤ n ≤ 10 You would use this equation for finding the cost of 10 shirts. Since 10 is equal to 10.
C(n) = 5n, 0 ≤ n ≤ 10 ← You can ignore the 0 ≤n ≤10 part.
C(10) = 5(10) Input the value 10 as x.
C(10) = 50 Simplified
Next,
C(n) = 4n + 5, n > 10 You would use this equation for finding the cost of 12shirts. Since 12 is greater than 10.
C(n) = 4n + 5, n > 10 ← You can ignore the n>10 part.
C(12) = 4(12) + 5, n > 10 Input the value of 12 as x.
C(12) = 48 + 5 Simplify
C(12) = 53
Finally,
The question is asking you to find the difference between the cost of 12 shirts and the cost of 10 shirts. So the formula would be C(12) - C(10).
C(12) - C(10)
(53) - (50) Input the values of C(12) and C(10).
= 3 Simplify.
The answer is 3.
Convert each mixed number to an improper fraction
--------------------------------------------
Convert 6&1/2 to an improper fraction
6&1/2 = (6*2+1)/2
6&1/2 = (12+1)/2
6&1/2 = 13/2
--------------------------------------------
Do the same for 9&1/4
9&1/4 = (9*4+1)/4
9&1/4 = (36+1)/4
9&1/4 = 37/4
--------------------------------------------
Now multiply the improper fractions 13/2 and 37/4. Multiply straight across
(13/2)*(37/4) = (13*37)/(2*4)
(13/2)*(37/4) = 481/8
--------------------------------------------
The last step is to use long division to find the mixed number equivalent of 481/8
Or we an say
60*8 = 480
So 60*8+1 = 480+1
which means
481/8 = (480+1)/8 = 480/8+1/8 = 60&1/8
Making the final answer to be choice C
Another way to get the answer is to convert 481/8 into a decimal to get 60.125 and then convert that back to a mixed number. You should get 60&1/8
