Step-by-step explanation:
1. divide 78% by 100 = 0.78
2. multiply 0.78 and 3.822
3. solve and get 2.98116
4. if you want you could round
5. x = 2.98166 or 3
Answer:
<u>Option A</u>
Step-by-step explanation:
We need to find the solution to the inequality.
<u>Steps </u><u>of </u><u>cancelling :-</u>
- <em>Cancel -8( which is on the numerator) and -8 (on the denominator) :</em>
- <em>Cancel 3(which is on the numerator)</em><em> </em><em>and 3( which is on the denominator)</em><em> </em>:
<em>As we know 1y equals to y.</em><em> </em>So,
<u>Steps </u><u>of</u><u> cancelling:-</u>
- <em>Cancel 3 (which is on the numerator) and cancel 3 (which is on the denominator)</em><em>:</em>
- <em>Cancel 4 and -8 </em><em> </em><em>:</em>
This matches with option A.
Hence, Option A is correct!

Answer:
5.4×10^-1
Step-by-step explanation:
An adjustment in the exponent is needed to get to scientific notation at the end.
(9×10^5)(6×10^-7) = (0.9×10^6)(6×10^-7) = (0.9×6)×10^(6-7)
= 5.4×10^-1
_____
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
_____
Of course, it can be useful to understand how moving the decimal point changes the exponent:
9 = 0.9×10 = 0.9×10^1
Answer:
The distance formula is 22.360679775
if you round it to the nearest tenth, then the answer is 22.4
Step-by-step explanation:
(-6, -12) and (4,8)
<u>(x2 - x1)² + (y2 - y1)²</u>
Place the x and y values
(4 - - 6)² + (8 - - 12)²
= 10² + 20²
= 100 + 400 = 500
√500 = 22.360679775
Round it to the nearest tenth, and you will get 22.4
