Answer:
-0.7
Step-by-step explanation:
First do 3.2-1.8= 1.4. So now we know that -2n=1.4. Next you solve for n to get the answer of -0.7 with your answer of the third option.
Answer:
16π square centimeters.
Step-by-step explanation:
The area of a circle is πr².
Here, we are given the diameter, but we just need to divide it by 2 to get the radius.
8/2 = 4
So, the radius is 4 cm.
Now, we can substitute it into the formula to find the area.
π x 4²
π x 16
16π
So, the area of this circle is 16π.
Answer:

Step-by-step explanation:
$12.75 - 6 × $2.10 = $12.75 - $12.60 = $0.15
Answer: 15 cents
Answer:
2(x-3)(x+2)
Step-by-step explanation:
2x^2 - 2x - 12
2(x^2 - x -6)
2(x^2 - 3x + 2x - 6)
2(x(x - 3) + 2(x - 3))
2(x-3)(x+2)
Answer:
51 minutes!
Step-by-step explanation:
<em>Hello there fellow human!</em>
First off, you convert kilometers to miles.
1 kilometer = 0.62 miles; therefore, 8 kilometers = 8*0.62 = 4.96 miles
Next, you determine how many minutes it takes for John to cover 1 mile
which is gotten by dividing 41 by 4;
41 / 4 = 10.25. So it takes 10.25 minutes to cover 1 mile. (minutes per mile)
Next, you multiply the number of minutes taken to cover <em>1 mile (10.25)</em> by <em>4.96 miles (8 kilometers)</em>, 10.25 * 4.96 = 50.84 minutes. Rounding that to the nearest minute, you get 51 minutes which make sense because the amount of time taken to cover 4 miles (41 minutes) will be shorter than the time taken to cover 4.96 miles (50.84 minutes) since 4 miles is smaller than 4.96 miles.

All calculations where done with a calculator. If you don't have that, you can always divide manually and convert to fraction.
