If the area of a square is 100 cm2, what is the perimeter?​

Mathematics
1 answer:
Vitek1552 [10]2 years ago
6 0

Answer:

40

Step-by-step explanation:

To find the perimeter, first we need to find the side lengths.

If 100 cm is the area then we need to find what number squared is 100

10 x 10 = 100

So 10 is the side length. P= s + s + s +s

10 + 10 + 10 +10 = 40

Find the indefinite integral. (use c for the constant of integration.) sin3 5θ cos 5θ dθ
Elina [12.6K]

I'm guessing you mean

\displaystyle\int\sin^35\theta\cos5\theta\,\mathrm d\theta

Let t=5\sin\theta. Then \mathrm dt=5\cos5\theta\,\mathrm d\theta. So we have

\displaystyle\int\sin^35\theta\cos5\theta\,\mathrm d\theta=\frac15\int\sin^35\theta(5\cos5\theta)\,\mathrm d\theta

=\displaystyle\frac15\int t^3\,\mathrm dt

=\dfrac{t^4}{20}+C

=\dfrac{\sin^4\5\theta}{20}+C

The legs of a right triangle are 6 units and 7 units. What is the length of the hypotenuse?
Ksju [112]

Answer: Square root 85 units

Step-by-step explanation:

Given: The legs of a right triangle are 6 units and 7 units.

Let h be the hypotenuse of the right triangle.

By Pythagoras theorem of right triangle, we have

h=\sqrt{6^2+7^2}\\\\\Rightarrow\ h=\sqrt{36+49}\\\\\Rightarrow\ h=\sqrt{85}

Hence, the  length of the hypotenuse=\sqrt{85}\text{ units.}

  • Pythagoras theorem of right triangle says that the square of the hypotenuse  is equal to the sum of the squares of the other two sides.

a farmer has a rectangular field that measures 125 feet by 200 feet. He wants to enclose the field with a fence. What is the tot
grandymaker [24]
He needs to fence the entire perimeter, so all you have to do is find the perimeter. P= S+S+S+S, which is 125, 200, 125, and 200. Add them together and you get 650, so he needs 650 feet of fence.

Julie had $20.00 in her pocket. She spent $7.40. About what percent of her money does she still have?
posledela

63%


First, we have to take 20.00 - 7.40 which gets us 12.60.


Then, we use the formula where we put the 12.60 on top of a fraction bar, and the 20.00 on bottom.

We do 12.60 x 100 which makes 1260.


Lastly, we divide that by the 20.00 which gets us 63.


So, Julie has 63% of her money left.


I hope this helped!!!
