Answer:
14.004m
Step-by-step explanation:
Using the SOH CAH TOA trigonometry identity
Tan theta = opposite/adjacent
Given
AB = opposite
BC = adjacent = 20cm
theta = 35 degrees
Substitute
tan 35 = AB/20
AB = 20tan35
AB = 20(0.7002)
AB = 14.004cm
Hence the length of AB is 14.004m

Three numbers add up to 210. The second number is 10 more than the first and the third number is 3 times the first. Find the numbers by modelling the problem using an algebraic equation.
Answers
Answer:
I. First number, a = 40.
II. Second number, b = 50.
III. Third number, c = 120.
Step-by-step explanation:
Let the three numbers be a, b and c respectively.
Given the following data;
Translating the word problem into an algebraic equation, we have;
a + b + c = 210
b = a + 10
c = 3a
Substituting the value of b and c into the equation, we have;
a + a + 10 + 3a = 210
5a + 10 = 210
5a = 210 - 10
5a = 200
a = 200/5
a = 40
To find the value of b;
b = a + 10
b = 40 + 10
b = 50
To find c
c = 3a
c = 3*40
c = 120

Answer: they are equal
To write a fraction as a percentage the easiest method is if we can change the denominator to 100.
#3/40 xx2.5/2.5 = 7.5/100 = 7.5%#
In many cases that method does not work,
so we can also do this by #xx 100%#

How come this person didn’t divide EVERYTHING on the left by 2? I thought you had to...
Answers
The short answer is that algebra doesn't work that way. You wouldn't divide *everything* by 2, but every term that contains a factor of 2.
In the expression
2 (6x - 1) + 2 (2x + 5)
both terms have a factor of 2 (the 2 out in front of them). They're the ones that get canceled when dividing by 2:
(2 (6x - 1) + 2 (2x + 5)) / 2 = 2/2 (6x - 1) + 2/2 (2x - 5)
… = 1 (6x - 1) + 1 (2x - 5)
… = (6x - 1) + (2x - 5)
and so on.
Looking ahead, it turns out that the equation is solved by x = 7. This makes 6x - 1 = 41 and 2x + 5 = 19. So the equation is saying that, if you make these replacements,
2×41 + 2×19 = 120
If you divide *everything* on the left by 2, you end up with fractions:
(2/2)×(41/2) + (2/2)×(19/2) = 41/2 + 19/2
but 41 + 19 = 60, so the end result would be 30, but that's not the same as 120/2 = 60.

What is 8.478 in expanded form?
Answers
explanation: the 1000 expands form
The expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)
What is an expanded form of numbers?We break up a number according to its place value and expand it to show the value of each digit, this process is called the expansion of the numbers.
Given that, we are asked to find the expanded form of 8.478,
The expanded form is :-
8 = 1 place = 8×1
0.4 = 1/10 place = 4×1/10
0.07 = 1/100 place = 7×1/100
0.008 = 1/1000 place = 8×1/1000
Therefore,
8.478 = 8×1+4×1/10×7×1/100+8×1/1000
Hence, the expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)
