To start off, 5+7=12, so we already know how the number line will be laid out. We will have Point A on 5, and count up 7 units, plotting Point B on 12.
Answer:
decrease of 64.3%
Step-by-step explanation:
Percentage change can be calculated from ...
pct change = ((new value)/(original value) -1) × 100%
= (50/140 -1) × 100%
= (-9/14)×100% = -64 2/7% ≈ -64.3%
The price of crude fell about 64.3% in that period.
The answer is about 43. In other words, it was going 43 mph.
The perfect cubes less than 1000 are:
<span>1^3 = 1 </span>
<span>2^3 = 8 </span>
<span>3^3 = 27 </span>
<span>4^3 = 64 </span>
<span>5^3 = 125 </span>
<span>6^3 = 216 </span>
<span>7^3 = 343 </span>
<span>8^3 = 512 </span>
<span>9^3 = 729
</span>
so
<span>2^3 = 8 could only be 1 + 1, but this is 2, not 8. </span>
<span>3^3 = 27 could be 1 + 1, 1 + 8 or 8 + 8, but all of these are too small </span>
4^3 = 64 could be 1 + 1, 1 + 8, 1 + 27, 8 + 8, 8 + 27, 27 + 27.
<span> general proof that a^3 + b^3 = c^3 holds for no positive integers
</span>hope it helps
