How to Find the area of this figure

lorasvet [3.4K]

Answer:

370.97 cm²

Step-by-step explanation:

Break up this figure into a half circle and a trapezoid.

The radius of the half circle is half the diameter, or half of 14 cm, or 7 cm.

The area of this half circle is then A = (1/2)πr², which here is:

A = (1/2)π(7 cm)² = 76.97 cm².

The trapezoid has a width of 14 cm and two legs of length 24 and 18 cm respectively.

The area of this trapez. is (average of the leg lengths)(width), or

A = (24 + 18) /2 times 14 (all in cm), or:

A = (21 cm)(14 cm) = 294 cm²

and so the area of the entire figure is the sum of the two areas found above:

294 cm² + 76.97 cm² = 370.97 cm²

Which ordered pairs are solutions to the inequality y - 3x < -8?

7nadin3 [17]

Answer:

Option B,C and E are solution to given inequality $y - 3x < -8$

Step-by-step explanation:

We need to check which ordered pairs from given options satisfy the inequality $y - 3x < -8$

Ordered pairs are solutions to inequality if they satisfy the inequality

Checking each options by pitting values of x and y in given inequality

A ) (1, -5)

$-5-3(1)$

So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.

B) (-3, - 2)

$-2-3(-3) < -8\\-2-9$

So, this ordered pair is solution of inequality as it satisfies the inequality.

C) (0, -9)

$-9-3(0)$

So, this ordered pair is solution of inequality as it satisfies the inequality.

D) (2, -1)

$-1-3(2)$

So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.

E) (5, 4)

$4-3(5)$

So, this ordered pair is solution of inequality as it satisfies the inequality.

So, Option B,C and E are solution to given inequality $y - 3x < -8$

Albert deposits $2785 in an account that earns 3.9% interest compounded monthly. this function models the amount in the account

Step2247 [10]

The amount for the given data is found as, $\rm a = 2825(1+\frac{3.9}{12} )^{12t}$ .The given expression is true.

<h3>What is the amount?</h3>

The complete repayment of money at the end of the period for which it was borrowed is referred to as the amount.

The given data in the problem is;

P is the annual payment=2827

r is the rate of interest = 3.9%

n is the time period=12

The formula for the amount is found as;

$\rm a = p(1+\frac{r}{n} )^{nt}$

Substitute the given value;

$\rm a = 2825(1+\frac{3.9}{12} )^{12t}$

Hence the given expression is true.

To learn more about the amount, refer to the link: brainly.com/question/12184047.
