Answer:
11,200
Step-by-step explanation:
At first we use "BODMAS" rule.
Given,
(3.5×10^13)-(1.4×10^12)/3×10^9
So, we will break the brackets at first. With the help of excel, we can get the desired result. The following images will show you the step-by-step result.
Use "Number" instead of "general" in the excel sheet. You can use calculator too.
To transform a mixed number to an improper fraction, we must multiply the denominator by the large number, and add the numerator.
So for 
: 
But we also put this over the denominator in the mixed number, so we get: 
.
Then we do the same for 
:
Then we must find a common denominator. Let's use 21 (multiply 3 and 7):
Now that we have a common denominator, we can subtract across:
Since 
cannot be reduced any further, we are going to leave this as our answer.
So the answer is .
1.<AFC
2.<AFD
3.<AFE
4.<AFB
#5, 6 and 7
m<BAE = 59
m<BAC + m<CAD + m<DAE = m<BAE
4x - 20 + x + 12 + x + 1 = 59
6x - 7 = 59
6x = 59 + 7
6x = 66
x = 11
m<BAC = 4x - 20 = 4(11) - 20 = 24
m<CAD = x + 12 = 11 + 12 = 23
m<BAE = x + 1 = 11 + 1 = 12
answer
5.
m<BAC = 24
6.
m<CAD = 23
7.
m<BAE = 12
#8, 9 and 10
m<BAE = 130
m<BAC + m<CAD + m<DAE = m<BAE
3x - 10 + 2x + 5 + x + 15 = 130
6x + 10 = 130
6x = 120
x = 20
m<BAC = 3x - 10 = 3(20) - 10 = 60 -10 = 50
m<CAD = 2x + 5 = 2(20) + 5 = 40 + 5 = 45
m<DAE = x + 5 = 20 + 15 = 35
answer
8.
m<BAC = 50
9.
m<CAD = 45
10.
m<DAE = 35
Answer:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 13 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 13 is 100%, so we can write it down as 13=100%.
4. We know, that x is 100% of the output value, so we can write it down as x=100%.
5. Now we have two simple equations:
1) 13=100%
2) x=100%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
13/x=100%/100%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 100% of 13
13/x=100/100
(13/x)*x=(100/100)*x - we multiply both sides of the equation by x
13=1*x - we divide both sides of the equation by (1) to get x
13/1=x
13=x
x=13
now we have:
100% of 13=13
