A rectangular field is 50 yards wide and 100 yards long. Patrick walks diagonally across the field. How far does he walk
S_A_V [24]

Answer:

Patrick walk approximately <u>112 yards</u>.

Step-by-step explanation:

Given:

A rectangular field is 50 yards wide and 100 yards long.

Patrick walks diagonally across the field.

Now, to find the distance he walk.

Length of the field = 100 yards.

Width of the field = 50 yards.

Now, to get the diagonal distance we put formula:

Diagonal = \sqrt{length^2+width^2}

Diagonal = \sqrt{100^2+50^2}

Diagonal = \sqrt{10000+2500}

Diagonal = \sqrt{12500}

Diagonal = 111.80

Therefore, Patrick walk approximately 112 yards.

Which is the quotient if 3/5 and 1/10?
AlladinOne [14]

Answer:

6

Step-by-step explanation:

We have two fractions and are asked to find the answer if they both are divided.

3/5 and 1/10.

When we divide fractions, we need to follow KCF

KEEP - Keep the fractions

CHANGE - Change the division sign to a multiplication sign

FLIP - Flip the second fraction

Follow :

KEEP :

3/5 / 1/10

CHANGE :

3/5 * 1/10

FLIP :

3/5 * 10/1

Now we need to multiply, which is simple because it's multiplying across :

\frac{3*10}{5*1}

30/5

Simplify by dividing the numerator and denominator by 5 :

\frac{30/5}{5/5} = \frac{6}{1}

Divide the numerator by denominator :

\frac{6}{1} = 6
