A builder is buying property where she can build new houses. The line plot shows the sizes of the lots for each house. What is the average size of the lots?

Answers

Answer:

Average size of the lots = ⅓ acre

Step-by-step explanation:

The question incomplete without specifying what we are to determine.

Question:A builder is buying property where she can build new houses. The line plot shows the sizes for each house. 1/6 has 6 X's 1/3 has 3 X's and 1/2 has 6 X's. Organize the information in a line plot. What is the average size of the lots? _________ acre

Help anyone?

Solution:

We are asked to organize the information in a line plot. See attachment for the line plot.

Given: 1/6 has 6 X's 1/3 has 3 X's and 1/2 has 6 X'sIn no particular order, the sizes of the lots are:1/6, 1/6, 1/6, 1/6, 1/6, 1/6, 1/3, 1/3, 1/3, 1/2, 1/2, 1/2, 1/2, 1/2 and 1/2 acre.

Let's count the number of lot for each size given.

For 1/6: there are 6 X's on the line plot of 1/6 number of lot for 1/6

= the lot × number of times it occurs

= (1/6) × 6 = 6/6 = 1 acre

For 1/3: there are 3 X's on the line plot of 1/3 number of lot for 1/3 = the lot × number of times it occurs

= (1/3) × 3 = 3/3 = 1 acre

For 1/2: there are 6 X's on the line plot of 1/2 number of lot for 1/2

= the lot × number of times it occurs

= (1/2) × 6 = 6/2= 3 acres

To find average size of the lots, we would sum all lot for each given size then divide by the total number of lots given.Sum of all lot for each given size = 1+1+3

Sum of all lot for each given size = 5

The total number of lots given = 15

Average size of the lots = 5/15 = 1/3

Average size of the lots = ⅓ acre

Hope this helps! :)

Cindy is saving for a trip to Hawaii. Each week, she puts aside the same amount of money for her airfare. After 9 weeks of saving, she needs $390 more for her airfare. After 14 weeks, Cindy still needs $240. How much does Cindy put aside each week for her airfare? How much is the airfare to Hawaii?

Answers

Answer:

I might be wrong but I did the calculations and my answer is that she put $30 aside each week and the airfare to hawaii is $660

Step-by-step explanation:

This is how I find my answer

first:

14 weeks - 9 weeks = 5 weeks

$390 - $240 = $150

$150/5 = $30 ( that is what she save per week)

then I did

$30 x 140 = 420 + 240 = $660

What is the size of the field in square feet, to the nearest whole?

Answers

Answer:

To find the Radius R we need Diameter which 290 fee so:

R = Diameter / 2

R = 290/2

R = 145 ft

Now put values in Area Formula

Area = 3.14 x (145)^2

Answers

9514 1404 393

Answer:

  No. Since 7^2 + 9^2 ≠ 11^2, the triangle cannot be a right triangle.

Step-by-step explanation:

You may recall that side lengths of 3, 4, 5 make a right triangle. That particular triple has several interesting characteristics. One is that it is the only (reduced) triple that is an arithmetic sequence (has a constant difference between the side lengths). Any right triangle that has sides that differ by a constant amount must be a multiple of 3, 4, 5.

Here, we have sides of length 7, 9, 11—values that differ by 2. They form an arithmetic sequence that is not a multiple of 3, 4, 5, so we know right away they cannot be sides of a right triangle.

If we want to use the Pythagorean relation to check, we can see if the equation is true:

  7² + 9² = 11²

  49 + 81 = 121

  130 = 121 . . . . . . Not True
