Answer is :

why ?

if they don"t show

2x3 =6

2x7 = 14

14x6 = 84

thats why b. might be the answer correct me if im worng from - dark enchantress cookie

FinnZ [79.3K]

Neighbor: 2/5(x) 
Remainder = x - 2/5(x) = 3/5(x) 
Cousin = 4/9 * 3/5(x) = 4/15(x) 

x - 2/5(x) - 4/15(x) = 15 
x - 6/15(x) - 4/15(x) = 15 
x - 10/15(x) = 15 
(15x - 10x) = 225 
5x = 225 
x = 225/5 = 45 

Therefore, he made 45 rolls

A bee flies 6 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 12 minutes, and then fli

AysviL [449]

Remark

You have to do a little subtracting and a little interpreting to get the answer. First you must assume that the bee travels in a straight line. This is math so we can assume this is true, although thousands would disagree.

Second you must assume that because it is loaded with nectar that it travels at a slower rate (not an unreasonable assumption).

Third you have to assume that the distance there is the same distance as coming back. Again this is math. We can make this assumption.

Find the travelling time.

The bee spends 12 minutes hunting down the nectar in the flowerbed. Since it was away from the hive for a total of 16 minutes, the travelling time is

16min - 12min = 4 min

Convert the Minutes to seconds.

1 minute = 60 seconds

4 minutes = 4*60 = 240 seconds.

Find the time each way.

The total time is 240 seconds, but it is not divided evenly.

Let the time there = t

Let the time back = 240 - t

The distances are the same.

r = 6 m/s

r1 = 4 m/s

t1 = t

t2 = 240 - t

dthere = dback

d = rate * time

6 m/s *t = 4 m/s (240 - t) Remove the brackets on the right.

6 * t = 4*240 - 4t Combine the like terms on the right.

6t = 960 - 4t Add 4t to both sides

6t + 4t = 960 - 4t + 4t Combine

10t = 960 Divide both sides by 10

10t/10 = 960/10 Do the division

t = 96 Time going to the flower bed

Find the distance

d = ?

r = 6 m/s

t = 96 second

d = r*t

d = 6 * 96 = 576 feet Answer

What is the area of this figure? Part 4 NO LINKS!!!

Vlad [161]

<h3>Answer: 414 square yards</h3>

========================================================

Explanation:

Surround the entire figure in a bounding rectangle as shown below.

This surrounding rectangle is 23 by 27. It's total area is 23*27 = 621 square yards.

For a moment, let's ignore the 3x3 section marked in the dashed lines. The empty space in the bottom left corner is 15+3 = 18 by 9+3 = 12. Its area is 18*12 = 216 square yards. Accounting for the dash line 3x3 section means we subtract 9 from the 216 to get 216-9 = 207. The empty space takes up 207 square yards.

So the purple region must take up 621-207 = 414 square yards
