Answer:
Step-by-step explanation:
<h3>Given</h3>
- P = 194
- l = 5w + 25
- l = ?, w = ?
<h3>Solution</h3>
<u>Perimeter formula</u>
<u>Substitute and solve for w:</u>
- 194 = 2(5w +25 + w)
- 194 = 12w + 50
- 12w = 144
- w = 144/12
- w = 12
<u>Find the length:</u>
Lets use 1 to solve this problem because it is easiest to show.
Multiply 1 by 1.3 for a 30% increase (1*1.3=1.3).
Then multiply 1.3 by .7 for a 30% decrease. (1.3*.7=.91)
Therefore the page had a 9% reduction from its original size or is 91% of its original size.
Plan 1 = 29.94 + 0.10x
Plan 2 = 32.99 + 0.05x
Plan 1 = Plan 2
29.94 + 0.10x = 32.99 + 0.05x
0.10x - 0.05x = 32.99 - 29.94
0.05x = 3.05
0.05x/0.05 = 3.05/0.05
x = 61
61 MB of data is needed to make both plan equal.
to check: x = 61
29.94 + 0.10(61) = 32.99 + 0.05(61)
29.94 + 6.10 = 32.99 + 3.05
36.04 = 36.04
There are 2 numbers that are 3 units from -6, it can be either from the left, in that case it would be -9, or to the right would be -3.
Answer:
0.1
Step-by-step explanation:
chance of pulling out a blue marble can be described as 8 equally probable outcomes (blue marbles) out of 20 equally probable outcomes (all marbles).
Similarly, the chance of pulling out a green marble is 5 out of 20.
In total, we have 8*5 (combinations of blue then green) outcomes out of 20*20 (any two marbles):
8*5 / (20*20) = 40 / 400 = 1/10 = 0.1
