Hey there!
A common ratio is just that number that you multiply or divide to each number that gets you the next in a geometric sequence. In this sequence, we know the numbers are getting bigger and we're multiplying, so we want to know what you're multiplying by the first number to get to the second. We can call this unknown number x. SO if we start with the first number and set up an equation, we get:
3x = 12
Divide both sides by 3
x = 4
Therefore, your common ratio is 4.
To check, you can multiply all the next numbers by 4 to see that it all checks out.
Hope this helps!
The variable represents the number of times Chris washes the car.
Surface area is the area of a base so:
We have to mulityply the height by the length to find the answer so the answer would be 4x6 which is 24square cm hope this helps!
Answer:
<h2>13</h2>
Step-by-step explanation:
6+
(4)(12)
/12
−2+5
=6+
48
/12
−2+5
=6+4−2+5
=10−2+5
=8+5
=13
When you divide by a fraction all you have to is multiply by the reciprocal. The reciprocal of 3/8 is 8/3.
<span>The real problem is 2/3 TIMES 8/3. Multiply the numerators across 2 X 8 = 16. Then multiply the denominators across 3 X 3 = 9. The answer is 16/9. If you need to simplify then the answer is 1 7/9.</span>
