Answer and Step-by-step explanation:

$Let's~solve~your~problem!$

Formula :

$speed=\frac{distance}{time}$

Solving for time:

$Time~taken~to~cover~40~miles~on~local~ roads~= \frac{40}{20} = 2~hours$

$Time~taken~to~cover~180~miles~on~the~highway~=$ $\frac{180}{60}=3~hours$

$Total~Time~=~5~hours$

Solving for distance:

 $Total~Distance=40 + 180 = 220$ 

Average speed:

 $\frac{Total~distance}{Total~time} = \frac{225}{5} = 44~miles~per~hour$

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
P(t) = Po(1 - r)^t

P(t) = price after t months --> S
Po = initial price -- P
r = rate as a decimal

S = P(.9)^4
-> = 100(.9)^4
-> = 65.61

(100 - 65.61)/100
34.39/100

Find the length to the nearest centimeter of the diagonal of a square 30 cm. on a side

tiny-mole [99]

Answer:

42 cm.

Step-by-step explanation:

Please find the attachment.

Let x be the length of diagonal of the square.

We have been given that length of each side of a square is 30 cm. We are asked to find the length of the diagonal of square to the nearest centimeter.

We can see from our diagram that triangle AC is the diagonal of our square.

Since all the interior angles of a square are right angles or equal to 90 degrees, so we will use Pythagoras theorem to find the length of diagonal.

$AC^2=AD^2+DC^2$
