Answer:

Step-by-step explanation:

To find the area subtract the area of the semicircle from the area of the rectangle.

Although the line isn’t there, if you imagine there is one, then you will see that you form a rectangle which is the same line as the semicircle’s diameter.

The area of rectangle is:

⇒ A = lw

⇒ A = (14)(8)

⇒ A = 112cm^{2}

The area of the semicircle;

⇒ A = \frac{1}{2}\pi r^{2}

⇒ A = \frac{1}{2}\pi (7)^{2}

*Note here that the radius is half the diameter, so it is 7cm, not 14cm

⇒ A = 76.97cm^{2}

Finally subtract the two areas;

⇒ A = 112 - 76.97

⇒ A = 35.03cm^{2}

Since we know that there is a 1 in 12 chance that the spinners will land on "4" and "C" and we know the total amount of spins is 240, we can find one twelfth of 240. To do so, you multiply 240 by 1/12 which is the same as 240/12. This can be simplified to 20 through division. Therefore, the answer is 20 times.

I hope this helps.<span />

Answer:

  • 367.6 m

Step-by-step explanation:

Use trigonometry

<u>Let the height of the cloud be x, then we have:</u>

  • tan 35° = x/525
  • x = 525 tan 35°
  • x = 367.6 (rounded)

The height of the cloud layer is 367.6 m

Strawberries cost $2 per pound. Kate buys 5 pounds and gets 20% discount on the total cost. How much does Kate pay for the straw
Tema [17]

The total cost without the discount is given by:

C = (2) * (5)\\C = 10$

Then, to find the discounted amount, we make the following rule of three:

10 $ ------------------> 100%

x ----------------------> 20%

From here, we clear the value of x.

We have then:

x = (\frac{20}{100}) * (10)\\x = 2

Then, the cost of the Strawberries with the discount is:

10 - 2 = 8 $

Answer:

Kate pays for the strawberries about $ 8.
