Answers

Answer 1

Answer: In order to solve this word problem this will be identified in an algebraic expression between the given numbers and values. Given are: Let, N = 1.5 x Jill J = Jill T = Jill + 15 kilograms Solution is: 1. N + J + T = 190 kilograms 2. 1.5J + J + (J + 15) = 190 3. 3.5J + 15 = 190 4. 3.5J =190 – 15 5. 3.5J = 175 6. J = 175/3.5 = 50
Therefore Jill weighs 50 kilograms,

Answer 2

Mathew is watching a car race on TV. His favorite car covered 10 laps of 3.6 miles each in 18 minutes. What is average speed of the car in miles per hour?

Answers

In the given question, all the necessary information's are already provided. Using these information's it is easy to find the average speed of the car in miles per hour. It is given that the car covers 10 laps in 18 minutes and each lap is 3.6 miles in length.
Total distance covered by the car = (10 * 3.6) miles
   = 36 miles
Now we have to convert the time from minutes to hours. So
18 minutes = 18/60 hours
   = 3/10 hours
Now we can easily calculate the average speed of the favorite car of Mathew.
Average Speed = 36 * (10/3) miles/hour
   = 120 miles/ hour

The most accurate way would be the fourth answer, because to estimate 66% of 47 you need to round both as closely as possible. 66% rounds closest to 2/3, and 47 is closest to 48

The last option is the most accurate. Here is how you can solve it:
1) Turn fractions into decimals
2/3 =0.666666667
1/4 =0.25
1/4 =0.25
2/3 =0.666666667

2) Multiply
0.666666667 x 50 = 33.333333...
0.25 x 48 = 12
0.25 x 50 = 12.50
0.666666667 x 48 = 32

3) To find what 66% of 47 is, you turn 66% into a decimal and multiply it by 47.
0.66 x 47 = 31.02

66% or 47 is 31.02

2/3 x 48 equals 32, and since it is the closest to 31.02. Therefore, the last option is the best option.

Students in a class were asked to name their favorite sport they like to watch on television. How many more time students want to watch basketball over students who want to watch soccer? Basketball 25.5%Soccer .03%

Answers

First, we need to add up all the percentages to make sure we have 100%.

25.5% + 0.03% = 25.53%

This means that 74.47% of the students chose something other than basketball or soccer.

The amount of students you stated there were was 2553.

25.5% of 2553 is 651 students and

0.03% is 8 students.

Now, we divide 651 by 8 to determine the amount of times over basketball was chosen.

651 ÷ 8 = 81

Basketball was chosen 81 times over again compared to soccer.

To find how much more times basketball was chosen, subtract 8 from 651

651 - 8 = 643

Basketball was chosen 643 times more than soccer.
