Looking at a number in different ways can help understand it’s application better. For example, giving an answer with radicals(square roots) is precise, but it’s not practical because you really don’t know what that number means.
Answer: D. $0.90
Explanation:
Day 1 = $0.10
Day 2 = $0.10 + double the last fine which is $0.20 = $0.30
Day 3 = $0.30 + $0.30 = $0.60
Day 5 = $0.60 + $0.30 = $0.90
Answer:
Four
Step-by-step explanation:
Thus, any whole can be divided into four equal parts and each part is one-fourth or a quarter of the whole. It is expressed as 1/4 and read as one over four or one upon four. If we consider two parts of the four equal parts of a whole it will represent 2/4 or two fourths, i.e. two one-fourth or half.
Answer:
x = -5, 7
Step-by-step explanation:
Step 1: Write equation
x² - 2x - 35 = 0
Step 2: Solve for <em>x</em>
<u>Factor:</u> (x - 7)(x + 5) = 0
<u>Find roots:</u> x = -5, 7
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
(-5)² - 2(-5) - 35 = 0
25 + 10 - 35 = 0
35 - 35 = 0
0 = 0
7² - 2(7) - 35 = 0
49 - 14 - 35 = 0
35 - 35 = 0
0 = 0
