you do 45,600 divided by 22
which equals about 2,072.72

Each heir will receive 2072.72 inheritance.

We have to given that;

You divide an inheritance of $45,600.00 among 22 heirs.

And, To find each heir will receive inheritance.

Now, find each heir will receive inheritance as;

⇒ 45,600.00 divided by 22

⇒ 45,600 / 22

⇒ 2072.72

Thus, Each heir will receive 2072.72 inheritance.

Answers

sec= 1/(cos), you can add or subtract 360 degrees from any angle measurement without changing the value of any of the trig functions i.e. 405 degrees= 405-360=45. cos of 45 is sqrt(2)/2 so sec405= 2/sqrroot2

The minimum monthly payment for Fern's credit card is 2.5% of her balance or $40, whichever is higher. If Fern's balance at the end of her last billing cycle was $1950, what is her minimum monthly payment?A.$48.75
B.$40.00
C.$8.75
D.$88.75

Answers

Answer:

A. $48.75.

Step-by-step explanation:

We have been given that the minimum monthly payment for Fern's credit card is 2.5% of her balance or $40, whichever is higher.

First of all let us find 2.5% of $1950.

$\text{2.5\% of \$1950}=(2.5)/(100)* \$1950$

$\text{2.5\% of \$1950}=0.025* \$1950$

$\text{2.5\% of \$1950}=\$48.75$

Since the minimum monthly payment will be the higher amount among 2.5% of the balance or $40. As $48.75 is higher than $40, therefore, Fern's minimum monthly payment will be $48.75 and option A is the correct choice.

1950 * .025
48.75
A

What divides a design so that every point on one side of the line coincides with a point on the other side of it

Answers

Answer:

line of symmetry

Step-by-step explanation:

Final answer:

The term that represents a design divided so that every point on one side coincides with a point on the other side is known as symmetry. This involves an axis of symmetry dividing the design into two contrasting fields.

Explanation:

The concept in question is commonly known as symmetry, and it is often a key factor in design and visual arts. In a symmetrical design, every point on one side of the line, often referred to as the axis of symmetry, coincides with a corresponding point on the other side. This alignment creates a mirroring effect, dividing the entire design into two contrasting fields, like images divided on a poster. For instance, if you have a vertical line dividing a rectangle directly down the middle, and you have a circle on the left side of the line, a symmetrical design would have a corresponding circle on the right side.
