Answer:</h2>
Each month, 2.8% Ramon's earnings are spent on electricity.
<h2>
Step-by-step explanation:</h2>
You know, that 100 percent are his earnings - $1,880
Now, you need to find out, how much is 1%. You do that by dividing $1,880 by 100.
Now you have to divide the amount he pays on electricity - $53.3 by one percent of his earnings - $18.8
So, now you know, that he pays exactly 2.83511% of his earnings on electricity. But from assignment, you know, that it has to be rounded to the nearest tenth of a percent. The number is 2.8351. So we will round it to 2.8% ,because 3 is rounded down. (https://www.mathsisfun.com/rounding-numbers.html)
100% = $1,880
$1,880/100 = $18.8
$53.3/$18.8 = 2.83511
2.83511% ≈ 2.8%
Answer:
2A/h = b
Step-by-step explanation:
The formula for area of a triangle is
A = 1/2 bh
Multiply each side by 2
2A = 2*1/2 bh
2A = bh
Divide each side by h
2A/h = bh/h
2A/h = b
