The $2500 money must you deposit in a simple interest account to earn $500 in interest in 5 years at 4% annual interest.

It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.

It is given that:

simple interest account to earn $500 in interest in 5 years at 4% annual interest

As we know the simple interest formula is:

I = Prt

Here

I = $500

t = 5 years

r = 4% = 0.04

500 = P(0.04)(5)

P = 500/0.2

The money that must be deposited in a simple interest account to earn $500 is:

P = $2500

Thus, the $2500 money must you deposit in a simple interest account to earn $500 in interest in 5 years at 4% annual interest.

Answer:

Calculate the final displacement from 0 if an object first moves 3 cm to the left and then 5 cm to the right.

The final displacement is 2 cm to the RIGHT .

Step-by-step explanation:

You can cut 60 pieces of 1/4 foot each from a string that is 15 feet long by carrying out the operation 15 ÷ 1/4, which turns into multiplication by the reciprocal of the fraction, 15 x 4 equals 60.

The question is asking how many 1/4 ft pieces you can cut from a 15 feet long string. In other words, you want to divide the total length of the string by the length of each piece you're cutting out. So you will carry out a division operation: 15 ÷ 1/4. When dividing by a fraction, you actually multiply by its reciprocal. The reciprocal of 1/4 is 4, so 15 ÷ 1/4 becomes 15 × 4, which equals 60. Therefore, you can cut 60 pieces of 1/4 foot each from a string that's 15 feet long.

[tex]5.6 \times \_\_} = -19.04[/tex]

Let the number be x.

As we can see the first number is positive while the result is negative, therefore, the other number must be negative as well.

[tex]5.6 \times x = -19.04\\\\x = \dfrac{-19.04}{5.6}\\\\x = -3.4[/tex]

Hence, the value of x is -3.4.

The submarine's elevation after 10 minutes is 4200 feet if the Navy submarine descended from sea level at a rate of seven feet per second.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

A Navy submarine descended from sea level at a rate of seven feet per second writing the descendent rate as an integer.

The rate of drop is 7 feet per second. 7 x 10(60), or 7 x 600, would be the subs elevation.

Consequently, the sub's elevation would be 4,200 feet below sea level.

Thus, the submarine's elevation after 10 minutes is 4200 feet if the Navy submarine descended from sea level at a rate of seven feet per second.

3x = 2x-6

x = -6

Answer:

B

Step-by-step explanation:

The expressions a12 a4 and a8 a8 are equivalent because according to the laws of exponents, when multiplying terms with the same base, you add their exponents, resulting in both expressions equating to a16.

The question refers to whether the expressions a12 a4 and a8 a8 are equivalent. These expressions are using the laws of exponents, specifically, the rule which states that when you are multiplying terms with the same base, in this case, a, you add their exponents. Therefore, a12 a4 would actually equal a16 because 12 + 4 equals 16. Similarly, a8 a8 would equal a16 because 8 + 8 equals 16, so yes, these expressions are equivalent as they both simplify to a16.

Answer:

Angles that are congruent are complementary to the same angle

Step-by-step explanation:

see that attached figure to better understand the problem

we know that

Two angles are complementary if their sum is equal to [tex]90\°[/tex]

[tex]m<KJM=m<KLM=90\°[/tex]

[tex]m<KJC=m<MLC[/tex] -----> equation A

[tex]m<KJM=m<KJC+m<CJM[/tex]

so

[tex]m<KJC+m<CJM=90\°[/tex] -----> equation B

[tex]m<KLM=m<KLC+m<MLC[/tex]

so

[tex]m<KLC+m<MLC=90\°[/tex] -----> equation C

Substitute equation A in equation C

So

[tex]m<KLC+[m<KJC]=90\°[/tex]

That means------> angles ∠KLC and ∠KJC------> are complementary angles

therefore

Angles that are congruent are complementary to the same angle

The three numbers are found by forming and solving a system of equations: the first number is 19, the second is 18 (which is one less than the first), and the third is 31 (which is 5 less than twice the second and exceeds the first by 12).

To solve the problem of finding the three numbers, we can set up a system of equations based on the information given:

Now we can solve for x:

The first number is 19. The second number is 18 (19 - 1), and the third number is 31 (2(18) - 5).

Thus, the three numbers are 19, 18, and 31.

Answer:

The correct option is 2.

Step-by-step explanation:

It is given that Pauline spent $7.50 every day for 3 days.

Amount spent on each day = $7.50

Number of days = 3

Spent amount and expenditure are always negative.

Total amount of money she spent is

[tex]Total =(-7.50)(3)[/tex]

On simplification we get

[tex]Total =-22.50[/tex]

She spent $22.50 and required expression is (−7.50)(3) = −22.50. Therefore the correct option is 2.

The number whose 900% is 450 is 50.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

The number is 900% of it is 450.

let the number be x.

900% of x= 450

900/ 100 x= 450

9x = 450

x= 50

Hence, 900% of 50 is 450.

The answer is 1/6 after using the number line if the number expression is −1/3 − (−1/2).

It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.

It is given that:

The fraction numbers are 1/3 and -1/2

As we know,

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The number expression is:

−1/3 − (−1/2)

From the number line:

Drawing line segment length of 1/3 left side

Drawing line segment length of 1/2 left side

Taking difference using number line:

= 1/6

Also, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

= −1/3 − (−1/2)

= -1/3 + 1/2

= (-2+3)/6

= 1/6

Thus, the answer is 1/6 after using the number line if the number expression is −1/3 − (−1/2).
