Answer:

<u>8064 pounds</u> of hay a group of 24 cows can eat in two weeks.

Step-by-step explanation:

Given:

Some animals on farms eat hay to get energy. A cow can eat 24 pounds of hay each day.

Now, to find how many pounds a group of 24 cows can eat in two weeks.

In 1 one day a cow can eat hay = 24 pounds.

Number of cows = 24.

Number of days in 2 weeks = 7 ×2 = 14.

Now, the expression of getting the pounds of hay a group of 24 cows can eat in two weeks is:

24 ( 24 × 14 ).

<u><em>So, to evaluate the expression:</em></u>

<u><em /></u>24(24\times 14)<u><em /></u>

=<em> </em>24\times 336<u><em /></u>

= 8064\ pounds.

Therefore, 8064 pounds of hay a group of 24 cows can eat in two weeks.

Which is the most accurate way to estimate 66% of 14?
Svetlanka [38]

Answer:

9.1

Step-by-step explanation:

Typically when a question starts with which that means there are several options to choose from. Or multiple choice. Since you haven't provided that here, I'll tell you how I would estimate it.

50% of 14 is 7

10% of 14 is 1.4

5% of 14 is 1/2 of 10% of 14 which is 0.7

50% + 10% + 5% = 65%

Add them together: 7+1.4+0.7 = 9.1

Consider a TV set that consumes 120 W of electric power when it is on, and is kept on for an average of 6 h per day. For a unit
Andru [333]

The cost of electricity consumed by the TV per month is <u>$4.968</u>.

In the question, we are given that a TV set consumes 120W of electric power when switched on. It is kept on for a daily average of 6 hours per day. The number of days in the month is given to be 30 days. The cost per unit of electricity is 23 cents per kWh.

We are asked to find the cost of electricity the TV consumes in the month.

The daily energy consumed by the TV = Power*Daily time = 120*6 Wh = 720 Wh.

The monthly energy consumed by the TV = Daily energy*Number of days in the month = 720*30 Wh = 21600 Wh = 21600/1000 kWh = 21.6 kWh.

Hence, the total cost of electricity the TV consumes = Monthly energy*Per unit cost = 21.6*23 cents = 496.8 cents = $496.8/100 = $4.968.

Therefore, the cost of electricity consumed by the TV per month is <u>$4.968</u>.

What is 2/3 multiplied by 3/4 simplified? I need step by step to get answer.
Masteriza [31]
You start with the top number of each fraction and multiply them. So 2x3=6. Next you take the bottom number and multiply. So 3x4=12. That would give you a fraction of 6/12. 6 is half of 12 so 6/12 simplified is equal to 1/2. Hope this helps!
