irina1246 [14]

2.9 percent of Ramon's earnings are spent on electricity each month.

<u>Step-by-step explanation:</u>

given

Amount that Ramon earns each month=$1835

Amount Ramon pays on electricity=$53.5

we have to calculate what percentage of $1835 is $53.5

The amount spent on electricity is 2.9% of his earnings

During a snowstorm, snow accumulated at a constant rate of 8/3 centimeters per hour. if the snow continued to fall at that rate
ikadub [295]

Answer:

16 centimeters

Step-by-step explanation:

The constant rate is 8/3 (cm/hr)

8/3 = 2.67 (rounded to hundredths place)

Multiply the dividend by the time, which is 6 hours

2.67 x 6 = 16.02

Therefore, 16.02 (or 16 depending on how you rounded) centimeters accumulated on the ground.

Jason spends 3 1/12 hours biking and 2 1/3 hours at the mall. How much less time does Jason spend at the mall compared to biking
aleksley [76]

We must find the difference between 3 1/12 and 2 1/3. So we can first subtract 3 from 2 and we earn 1 whole number. Next we must subtract  1/12 and 1/3. This is the same as 3/36-12/36, which is -9/36 or -1/4. Since we can't have -1/4 we must subtract 1/4 from 1 and earn 3/4 as our answer.

Hope this helps! <3
