find the simple interest principle 950 interest rate 12% time 4 years

Answers

Answer:

A= $1406

Step-by-step explanation:

The formula for simple interest is A=P(1+rt), where P=Principal, R=Rate, and T=Time. Before you plug your numbers into your formula, you must first convert 12% to a decimal (This is simple because all you have to do is divide 12 by 100.)- 0.12.

Now, you can plug your numbers into the formula: A=950(1+0.12x4). To make this less complex, I suggest working in the parenthesis first- specifically simplifying rt, or multiplying 0.12 by 4 (you should get 0.48)! Now, you are just about ready to go. A=950(1+0.48)- You can plug this into your calculator as is, or you can go on ahead and add the numbers in the parenthesis if that makes you feel better! (You should get 1.48).

Your final formula should be 950(1.48), and you should plug this into a TEACHER-APPROVED CALCULATOR to save time!

Your final answer should be $1406, otherwise you did something wrong! XD!

Solved for the value of y and found that y = 5.

What is the Pythagorean theorem?

In the Pythagorean theorem, the sum of the squares of the sides of a right-angled triangle is equal to the square of the longest side i.e, the hypotenuse of the triangle.

z² = x² + y²

The given triangle is a right-angled triangle. This means that we can use the Pythagorean theorem.

∴ y² + 12² = 13²

⇒ y² + 144 = 169

⇒ y² = 169-144

⇒ y² = 25

⇒ y = 5

Therefore, we have solved for the value of y and found that y = 5. The correct answer is option C.

When Shawn cleaned his room he found that the ratio of clean clothes to dirty clothes was 3 to 5 if 46 articles of clothing were discovered how many were clean

Answers

Answer:

17.25

Step-by-step explanation:

Ratio of clean clothes to dirty clothes = 3 : 5

Clean clothes = 3

Dirty clothes = 5

Total ratio = 3 + 5 = 8

Total clothing article = 46

how many were clean

Number of clean clothes = ratio of clean clothes / total ratio × total clothing article

= 3/8 × 46

= 0.375 × 46

= 17.25

Please help. I don't know-how

Answers

Answer: 4

You would set this up like so:

125 ≤ 29.50 + 19.50x

Subtract 29.50 from both sides.

You should be left with 95.50 ≤ 19.50x

From here, you wanna divide both sides by 19.50 (we do this to isolate the x)

You would get 4.89.

Since Tamesha can't buy half a shirt, you don't wanna round up. So, the answer should be 4.

Step-by-step explanation:

Trust Milky. Milky smart!

Answer:

she can buy 4 shirts

Step-by-step explanation:

maximum that she can spend = $125

dress = $29.50

shirt = $19.50

first, take 29.50 and subtract it from 125

⇒ 125 - 29.50 = $95.50 remaining

then take 95.50 and it divide it by 19.50 to determine how many shirts she can buy

⇒ [tex]\frac{95.50}{19.50}[/tex] = 4.897

⇒ 4 shirts

to solve:

take 4 shirts and multiply it by 19.50

⇒ 4 x 19.50 = $78

then take the product and add 29.50

⇒ 78 + 29.50 = 107.50

take the maximum money and subtract 107.50 from it

⇒ 125 - 107.50 = 17.5

Tamesha would have $17.50 remaining.

Since 1900, the Audubon Society has conducted an annual Christmas bird count, documenting the number of birds of each species seen in locations across the country. In the 2011 Christmas bird count, there were 3,813 red-tailed hawks seen and counted in Texas. In the 2012 count, there were 4,511 red-tailed hawks counted in Texas. Calculate the growth rate by dividing the difference in the numbers seen in the two years by the number seen in 2011. Then use this value to calculate the estimated population of red-tailed hawks in Texas in 2022, if the growth rate remains constant.

3 | 5 0

Remove the stems

3, 8

Mean = Sum/Count

So, we have:

Mean = (3 + 8 + 0 + 1 + 4 + 7 + 2+ 4 + 5 + 5 + 0)/11

Evaluate

Mean = 3.55

Step-by-step explanation:

Each sweatshirt cost $20, but we don't know how many sweatshirts someone will buy so we use X, representing the amount of sweatshirts. There is a shipping charge of $4.99, so we have to add that to the cost of the sweatshirts. 20x+4.99. Y is the total cost.

Quarters have a coating of copper mixed with nickel on the outside. If the diameter of a quarter is 24.3 mm, then what is the surface area of one side of the quarter that will get coated?

Answers

Answer: 463.96 mm² or 46.4 cm²

Step-by-step explanation:

Quarters are circular in shape so the surface area of one side will be the area of a circle.

Area of a circle = π * r²

Radius = Diameter / 2

= 24.3 / 2

= 12.15 mm

Area = 22/7 * 12.15²

= 463.96 mm²
