To find simple interest, you multiply the principal (in dollars), the interest rate (as a decimal), and the time in years.
The equation 22.80 = 300 •019•4 shows how to find the simple interest for a certain account after 4 years. What
is the interest rate (as a percent)? How much is the simple interest? What is the principal?
What is the interest rate (as a percent)?
A. 1.9%
B. 22.80%
C. 0.019%
D. 300%

Answers

Answer 1

Here we have $400 originally and it is invested at an interest rate of 0.015 for 4 years.

Therefore we can say that the interest rate is 0.015 * 4 * 100 = 6% for the 4 years.

Simple interest is 6% / 4 = 1.5%.

And the principal is $400.

what number has 62 ones, 20 ten thousands, and 300 tens

Hope it helped you brainiest plz and thank you have a great day!!!

The number for the given statement is 203,062.

We need to find what number has 62 ones, 20 ten thousand, and 300 tens.

How to write the number into a word statement?

In general, use words to express numbers zero through nine, and use numerals to express numbers 10 and above. However, there are exceptions to this general guideline for number usage.

Now, 62 ones=62×1=62

20 ten thousand=20×10,000=200,000

300 tens=300×10=3000

Now add all these numbers.

That is, 200,000+3000+62

=203,062

Therefore, the number for the given statement is 203,062.

Find a primitive Pythagorean triplet (a, b, c) where c=a+50.

Answers

Answer:

Pythagorean triple (PT) can be defined as a set of three positive whole numbers that perfectly satisfy the Pythagorean theorem: a2 + b2 = c2.

theorem: a2 + b2 = c2.

This set of numbers are usually the three side lengths of a right triangle. Pythagorean triples are represented as: (a, b, c), where, a = one leg; b = another leg; and c = hypotenuse.

There are two types of Pythagorean triples:

Primitive Pythagorean triples

Non-primitive Pythagorean triples

Primitive Pythagorean triples

A primitive Pythagorean triple is a reduced set of the positive values of a, b, and c with a common factor other than 1. This type of triple is always composed of one even number and two odd numbers.

For example, (3, 4, 5) and (5, 12, 13) are examples of primitive Pythagorean triples because each set has a common factor of 1 and also satisfies the

Step-by-step explanation:

Pythagorean theorem: a2 + b2 = c2.

(3, 4, 5) → GCF =1

a2 + b2 = c2

32 + 42 = 52

9 + 16 = 25

25 = 25

(5, 12, 13) → GCF = 1

a2 + b2 = c2

52 + 122 = 132

25 + 144 = 169

169 = 169.

Kim bought a blouse for $17.16, a skirt for $28.19, and a purse for $35.14. The sales tax was 12%. If she hands the clerk a $100 bill how much will she get back?

Answers

Based on the cost of her items, if Kim hands over $100, she will get back $9.85.

The total that Kim will pay includes the cost of all three items as well as the sales tax.

The total cost of the three items is:

= Blouse + Skirt + Purse

= 17.16 + 28.19 + 35.14

= $80.49

The total including the sales tax will be:

= Cost + (Cost x Sales tax)

= 80.49 + (80.49 x 12%)

= $90.15

The change she will get is:

= 100 - 90.15

= $9.85

In conclusion, Kim will get a change of $9.85.

It isn't being used at the moment, but is waiting to do work. A good example is to think about a boulder sitting on top of a hill. Just sitting there, the boulder isn't doing anything. But because it is sitting on top of a hill, it has the potential to roll down and do some damage to a car or building below. The energy is stored in that rock because of its size (mass) and the distance it will travel once it starts rolling. Another good example is a rubberband. When you stretch a rubber band, it wants to move back to its original position, and thus you have given it potential energy. As the rubber band is released, potential energy is changed to motion.Kinetic energy is energy of motion. A rubber band flying through the air has kinetic energy. When you are walking or running your body is exhibiting kinetic energy. This energy is performing work. Other examples of kinetic energy include: legs pump bicycle pedals, lightning snaps trees, cars travel down the street, football players making tackles, and 4-wheelers speeding through the woods.Potential energy is converted into kinetic energy. As mentioned before, a stretched rubberband can change from having potential to kinetic energy. Another example of this change between kinetic and potential energy can be seen using a yo-yo. Before a yo-yo begins to fall from your hand it has stored energy due to its position. At the top (in your hand) it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy. At the bottom its potential energy has been completely converted into kinetic energy so that it now has its maximum kinetic energy. Another example of the change between kinetic and potential energy is a waterfall. A waterfall has both potential and kinetic energy. The water at the top of a waterfall has stored potential energy. When the water begins to fall, its potential energy is changed into kinetic energy. This change in energy is used in Niagara Falls, Canada to provide electricity to parts of the northeastern United States.Questions:1. What is kinetic energy?2. What is potential energy?3.
