Answer:

153.86 un²

Step-by-step explanation:

Area circle = πr²

Radius is the distance of the center to the edge(perimeter)

Radius = 7

Area circle = 3.14(7)²

Area circle = 3.14 * 49 = 153.86

<h2>Solving for the Area of a Circle</h2><h3>Answer:</h3>

The area of the Circle $A$ is approximately $153.86$

<h3>Step-by-step explanation:</h3>

The area of a circle, $A_{\circ}$ , is calculated by $A_{\circ} = \pi r^2$ . We can see that the distance between point $A$ to any point on the circle is $7$ . This means that $7$ is the radius of the circle.

Solving for $A_{\circ}$ :

$A_{\circ} = \pi r^2 \\ A_{\circ} \approx 3.14(7)^2 \\ A_{\circ} \approx 3.14(49) \\ A_{\circ} \approx 153.86$

Suppose you are making granola bars with 3 cups of oats. How much quinoa, flaxseed, and soy protein would you use would you need

Andreas93 [3]

Answer: $\frac{3}{4}\ cup$ of quinoa, $\frac{3}{8}\ cup$ of flaxseed, $1\ cup$ of soy protein.

Step-by-step explanation:

<h3> The missing table is attached.</h3>

Let be "q" the amount of cups of quinoa you'd need to use making the granolas with 3 cups of oats.

Based on the table you can write the following proportion:

$\frac{\frac{1}{2} }{2}=\frac{q}{3}$

Solving for "q", you get:

$\frac{1}{4}=\frac{q}{3}\\\\q=\frac{3}{4}$

Let be "f" the amount of cups of flaxseed you'd need to use making the granolas with 3 cups of oats.

With the data given in the table you can write the following proportion:

$\frac{\frac{1}{4} }{2}=\frac{f}{3}$

Solving for "f", you get:

$\frac{1}{8}=\frac{f}{3}\\\\f=\frac{3}{8}$

Let be "s" the amount of cups of soy protein you'd need to use making the granolas with 3 cups of oats.

Using the table you can write this proportion:

$\frac{\frac{2}{3} }{2}=\frac{s}{3}$

Solving for "s", you get:

$\frac{1}{3}=\frac{s}{3}\\\\s=1$

Monique borrows $5000 at 5.5% interest compounded daily for 29 days. How much will she owe at the end of 29 days?

slega [8]

Answer:

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount borrowed

From the information given,

P = 5000

r = 9

5.5% = 5.5/100 = 0.055

Assuming they are 365 days in a year

n = 365 because it was compounded 52 times in a year.

t = 29/365 = 0.0794

Therefore,

A = 5000(1 + 0.055/365)^365 × 0.0794

A = 5000(1 + 0.00015)^29

A = 5000(1.00015)^29

A = $5022
