Given the total amount paid off and the interest, the original amount borrowed within the given period of time is $565.00

Simple interest is simply a method to determine the amount of interest charged on a sum at a given rate and for a given period of time.

It can be expressed as;

A = P( 1 + rt )

Given the data in the question;

To determine the initial amount borrowed, plug the given values into the equation and solve for P.

A = P( 1 + rt )

615.85  = P( 1 + ( 0.09 × 1 ) )

615.85  = P( 1 + 0.09 )

615.85  = P( 1.09 )

P = 615.85 / 1.09

P = $565.00

Given the total amount paid off and the interest, the original amount borrowed within the given period of time is $565.00

The Broadway theater had 100 Orchestra, 220 main seat and 190 balcony seats.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the number of Orchestra, y represent the main seat and z represent the balcony seat.

A Broadway theater has 510 ​seats, Hence:

x + y + z = 510    (1)

Also:

140x + 135y + 100z = 62700    (2)

And:

135y + 100z + (1/2)(140)x = 55700    (3)

From the three equations:

x = 100, y = 220, z = 190

According to the solving the capacity of the tank is  = 500

The term 'volume' in mathematics refers to the amount the three-dimensional space occupied by such an item or a closed surface. The volume is measured in cubic units like as m3, cm3, in3, and so on. Volume is also referred to as capacity at times.

Volume is the amount of three-dimensional space inhabited by a liquid, solid, or gas. Volume is commonly expressed in liters, cubic meters, gallons, milliliters, teaspoons, and ounces, while many additional units exist.

fuel storage tank is 3/4 full.

75 liters have been drawn off.

it is 3/5 full.

The capacity of the tank = ?.

So,

3/4x - 75 = 3/5x

3/4x - 3/5x = 75

Multiplying by 20 both the side:

15x - 12x = 1,500

3x = 1500

Answer:

the answer would be 0.364

Writing the ratios 25:4 and 45:10 as a complex fraction will be 6 1/4 and 4 1/2.

From the information, it should be noted that we want to write the ratios 25:4 and 45:10 as a complex fraction.

It should be noted that we simply have to convert the numbers to fractions. This will be:

25:4 = 25/4 = 6 1/4

45:10 = 45 / 10 = 4 5/10 = 4 1/2.

Answer:

Question 5 is true

Question 4 is false

Step-by-step explanation:

I am not sure about the first question because numbers that are either positive or negative are called integers, however, this is not one of the options.

Explanation:

So, looking at the ruler, we;re going to take the whole number of the measurment from the whole bars of inches it overlaps (1-3) since we know it goes past there we will have a fraction beside it (because it does not go all the way to 4) If you see the longest lines in between the 3 and 4, there are 3 bars (which means each is 1/4.) Now, we know that it covers 3/4 of the last inch. To convert to /8, we multiply the numerator and denominator by 2 so we have 6/8. The CLOSEST (but not completely correct) (in 1/8 inches) would be D. (but ONLY if A is incorrect because that is simplified and the accurate answer.

On the other hand, low-cost manufactured items are produced and exported by China, Thailand, and Vietnam. These three nations enjoy a distinct advantage as a result of their significantly reduced unit labor costs.

The moment of inertia (I) solved for, from the angular kinetic energy formula is I = 2E/w².

Angular kinetic which is also referred to as  rotational energy is simply the kinetic energy due to the rotation of an object.

It is expressed mathematically as;

E = (1/2)Iw²

To solve for I, we first reorder the equation to bring the term containing I to the left side.

E = (1/2)Iw²

(1/2)Iw² = E

Multiply both sides by 2

2 × (1/2)Iw² = 2 × E

Iw² = 2 × E

Iw² = 2E

Now, divide both sides by the question of I.

Iw²/w² = 2E/w²

I = 2E/w²

Therefore, the moment of inertia (I) solved for, from the angular kinetic energy formula is I = 2E/w².
