Answer:
34.45
Step-by-step explanation:
11÷2 = 5.5
so 5.5x5.30 = 29.15 + 5.30 = 34.45
Answer:
Q1
|a-b| = b-a when a<b
Q2
104159/33000
Step-by-step explanation:
Q1
If a<b then a-b will always be negative. To get the absolute value, we can take -(a-b) = -a+b = b-a.
Q2
Let x = 3.12789789789...
We isolate the repeating decimal to start after the decimal, so we multiply by 100.
100x = 312.789789789...
We want to multiply by 10 for each digit that repeats (in this case 3), to get the repeating part to the left of the decimal.
100000x = 312789.789789
Subtracting the two...
x(100000-100) = 312789.789789 - 312.789789
99900x = 312477
x = 312477/99000 = 104159/33000
Answer:
Domain: {-3, -1, 1}
Range: {-1, 2, 4, 5}
Step-by-step explanation:
The domain is all the x-values, and the range is all the y-values. When listing values, repeated values are only written down once.
A)
Increase %= (new # - old #)/old * 100
new= 8
old= 5
Increase %= (8-5)/5 * 100
=3/5 * 100
=0.60 * 100
=60% increase
B)
Decrease %= (old # - new #)/old * 100
new= 5
old= 8
Decrease %= (8-5)/8 * 100
= 3/8 * 100
= 0.375 * 100
= 37.5% decrease
ANSWER: a) 60% increase; b) 37.5% decrease
Hope this helps! :) Good luck on your test!!
Answer:
Step-by-step explanation:
There are two conditions that need to be in place.
- The sum of the angles must equal 180
- There must be exactly 3 angles.
A has too many angles. The answer is not A.
B same as A
C same as A
D doesn't add to 180. Not D
You have no answer unless there is another choice.
