Answer:

10π cm

Step-by-step explanation:

We require to find the radius (r) of the circle

The area (A ) is calculated as

A = πr² = 25π ( divide both sides by π )

r² = 25 ( take the square root of both sides )

r = [tex]\sqrt{25}[/tex] = 5

The circumference (C) is calculated as

C = 2πr = 2π × 5 = 10π cm

What are the properties of Triangle?

The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

Given, In ΔPQR, p = 220 inches, q = 890 inches and ∠R=121°.

From the general formula of side of triangle:

c² = a² +b² - 2ab * cos ∠C

In Our case,

a = p = 220

b = q = 890.

c = r

∠C = ∠R = 121 degrees

Thus,

r² = 220² + 890² - 2*220*890 * cos 121°

r² = 941344.455067

r = 970.229073501

r = 970 inches Approx.

Therefore, the value of r will be 970 inches Approx.

Margaret deposits $1,000 in a savings account that pays 1.4% interest compounded
semiannually. What is her balance after 1 year?

Answers

Answer:

The balance after 1 year is;

$1,014.05

Step-by-step explanation:

To do this, we use the compound interest formula

That will be ;

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

A is the amount generated which we want to calculate

r is the rate = 1.4% = 0.014

P is the amount deposited = $1,000

n is the number of times it is compounded annually which is 2 (semi-annually means 2 times in a year)

this the number of years which is 1

we have this as:

A = 1,000( 1 + 0.014/2)^(2*1)

A = 1,000(1 + 0.007)^2

A = 1,000(1.007)^2

A = $1,014.05

lowing equation:
5x - 6 = 44. Then solve for x

Answers

Answer:

x = 10

Step-by-step explanation:

Simplifying

5x + -6 = 44

Reorder the terms:

-6 + 5x = 44

Solving

-6 + 5x = 44

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6' to each side of the equation.

-6 + 6 + 5x = 44 + 6

Combine like terms: -6 + 6 = 0

0 + 5x = 44 + 6

5x = 44 + 6

Combine like terms: 44 + 6 = 50

5x = 50

Divide each side by '5'.

x = 10

Simplifying

x = 10

The library is having a book sale. Hardcover books sell for $4 each, and paperback books are $2 each. If Ayanna spends $26 for 8 books, how many hardcover books did she buy?​

Answers

she bought 5 hardcover books and 3 paperback books
5x$4= $20
3x$2= $6
$20+$6=$26

hope this helped

Answer:

5 hardcover books

Step-by-step explanation:

x + y = 8 ↔ Assume x for hardcover books and y for paperback cover

4x + 2y = 26 ↔ Total cost of 8 books is $26

-2x - 2y = -16 ↔ Multiply Equation 1 by -2 so that the coefficients of y is opposite

2x = 10 ↔ Add the two equations to eliminate y

x = 5 ↔ Divide each side by 2
