Answer:
41.6666666 the 6 will go one for ever
Step-by-step explanation:
Answer:
43 questions in total
Step-by-step explanation:
the original equation with the unknown (total number of questions on the test) will look like this
we know this because to work out a percentage in the 1st place you need the total ÷ number (in this case it's ÷ how many questions out of the total she did answer)
now you rearrange.
you need to move the 24 to get the total on it's own here's how you do it
what you do to one side of equation you have to do to the other. the 24 and 24 on the left will cancel because 24÷24=1 and we don't write
got mum of Q's x 1= 80 x 24
now you convert % to decimal
replace
now you take the original and + the 19
therefore there are a total of 43 questions on the exam
Divide 2.24/8 and you get your answer of:
0.28 per pencil
The obtuse interior angle in triangle can reach to 179.9999999.... °.
Because once it hits 180°, the angle becomes a straight line and it is not possible in a triangle.
Let's use an example. Start with 10.
If we move the decimal 3 places to the right, we get 10,000.
So from 10 to 10,000, we multiplied by 1,000.
Let's try it with 5 now:
If we move the decimal 3 places to the right, we get 5,000.
The same holds true. Therefore, it is the same as multiplying the number by 1,000 or B.
