Answer:

d≈7.07

Step-by-step explanation:

Using the formulas

P=4a

d= \sqrt{2} a

Solving ford

d= \sqrt{2} P/4=2·20 /4≈7.07107

Answer:

Then length of diagonal is 5√(2)

Step-by-step explanation:

Perimeter(p)=20

Perimeter of square(p)=4xLength(L)

20=4 x L

Divide both sides by 4

20/4=4L/4

5=L

L=5

Length of diagonal=√(5^2+5^2)

Length of diagonal=√(5x5+5x5)

Length of diagonal=√(25+25)

Length of diagonal=√(50)

Length of diagonal=√(25x2)

Length of diagonal=√(25)x√(2)

Length of diagonal=5x√(2)

Length of diagonal=5√(2)

Ira Lisetskai [31]

Answer:

Step-by-step explanation:

4/5 cup of brown sugar. Needs 1/4 cup. How many cups left?

Okay, so 4/5 = 0.80, 1/4=0.25.

0.80-0.25=0.55

Which is 55/100

Divide both numbers by 5

A standard roll of toilet paper is 304 feet long. If Bob walks at a steady rate of five feet per second, how much time does it t

PtichkaEL [24]

Answer:

1.01 minutes

Step-by-step explanation:

The length of the roll is given to be 304 ft, and Bob's velocity is 5ft/s.

Velocity is defined as the rate of change of displacement over time t:

$v=d/t\\$

The function can be expressed to make t the subject to calculate time taken by Bob;

$v=d/t\\\therefore t=d/v, d=304, v=5\\\\t=\frac{304}{5}\times \frac{1}{60}\ min\\\\t=1.01 \ min$

Hence, it takes Bob 1.01 minutes to walk the length of the roll.
