Let's make the length L and the width w. So, here's what we know:

L = 2w + 10

Lw = 1500

Substitute L in as 2w + 10:

w(2w + 10) = 1500.

Simplify.

2w squared +10w = 1500

Make it a quadratic equation, w = 25 or -30. Since it can't be negative, w = 25.

1500/25 = 60.

Length = 60
Width = 25

A yard is 3 times as long as it is wide. 176 feet of fencing is needed to enclose the yard. Find the dimensions of the yard
svet-max [94.6K]
The perimeter of a rectangle is twice the sum of its side lengths.

P=2(L+W), we are told that L=3W and P=176 so

2(3W+W)=176

2(4W)=176

8W=176

W=22 ft, since L=3W

L=66 ft

So the yard is 22 feet wide and 66 feet long.

lianna [129]

Answer:

28.5%  Internet users in 2003 were in the United States.    

Step-by-step explanation:

We are given the following in the question:

Number of people using the internet =

5.8078 \times 10^8

Number of people in United States =

1.6575 \times 10^8

Percent of Internet users in 2003 were in the United States =

=\dfrac{\text{Number of users in United States}}{\text{Number of internet user in world}}\times 100\%\\\\=\dfrac{ 1.6575 \times 10^8}{5.8078 \times 10^8}\times 100\%\\\\=28.5\%

Thus, 28.5%  Internet users in 2003 were in the United States.
