Answer:

The exact distance is \sqrt{109} miles.

The distance is approximately 10.4 miles.

Step-by-step explanation:

It is given that a rectangular city is 3 miles long and 10 miles wide. So,

Length = 3 miles

Width = 10 miles

We need to find the distance between opposite corners of the city. It means, we need to find the length of the diagonal of the rectangle.

Using Pythagoras theorem, the length of diagonal is

d=\sqrt{l^2+w^2}

where, l is length and w is width.

Substitute l=3 and w=10.

d=\sqrt{(3)^2+(10)^2}

d=\sqrt{9+100}

d=\sqrt{109}

The exact distance is \sqrt{109} miles.

Now,

d=\sqrt{109}

d=10.4403065

d\approx 10.4

The distance is approximately 10.4 miles.

help I will fail math class please help doors for the small cabinets are 11.5 inches long . doors for the large cabinet are 2.3
VARVARA [1.3K]
11.5 * 2.3 = large door size
large door size / 12 = large door size in feet
large door size in feet / 10 = how many large doors can be cut from the board. (you have to round it down if there's a decimal- no 1/2 doors.)
