The first step to solve this problem is to solve for the area of the square. The formula for the area of the square is:

A = a^2

Where a = measurement of the side of the square

A = 7^2

A = 49 cm^2

The second step is to solve for the area of the circle. The diameter of the circle can be drawn out of the side of the square which is 7 cm. Therefore, the radius of the circle is 3.5 cm. The formula in solving the area of the circle is:

A = pi (r)^2

A = 3.14 (3.5)^2

A = 3.14 (12.25)

A = 38.465 cm^2

To solve for the area of the shaded region, you have to deduct the area of the circle to the area of the square.

Asquare – Acircle = Area of the shaded region

49 cm^2 – 38.465 cm^2 = 10.54 cm^2 is the area of the shaded region

Please please help me with this.

Answer:

Step-by-step explanation:

Since the inequality is < then the line separating the shaded and plain regions will be broken.

Thus graph A or B

Choose a test point in each shaded region and check validity of solution

From A choose (0, 2), then

2 < 0 + $\frac{4}{7}$ → 2 < $\frac{4}{7}$ ← False

From B choose (0, - 2), then

- 2 < 0 + $\frac{4}{7}$ → - 2 < $\frac{4}{7}$ ← True

Thus the graph representing the inequality is B

A collection of dimes and quarters is worth $10.45. There are 70 coins in all. Find how many of each there are

Advocard [28]

There are 47 dimes and 23 quarters.

Step-by-step explanation:

Total amount = $10.45 = 10.45*100 = 1045 cents

Total coins = 70

1 dime = 10 cents

1 quarter = 25 cents

Let,

Dimes = x

Quarters = y

According to given statement;

x+y=70 Eqn 1

10x+25y=1045 Eqn 2

Multiplying Eqn 1 by 10;

$10(x+y=70)\\10x+10y=700\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(10x+25y)-(10x+10y)=1045-700\\10x+25y-10x-10y=345\\15y=345$

Dividing both sides by 15;

$\frac{15y}{15}=\frac{345}{15}\\y=23$

Putting y=23 in Eqn 1

$x+23=70\\x=70-23\\x=47$

There are 47 dimes and 23 quarters.
