Decide whether −3/12 terminates or repeats when expressed as a decimal

Answers

It terminates. When you put this into your calculator, you get -0.25. It terminates, or ends, after the 5.

A repeating decimal is like this...

Answer:

R = 30

Step-by-step explanation:

Given y is directly proportional to R² then the equation relating them is

y = kR² ← k is the constant of proportion

To find k use the condition when R = 4, y = 24, then

24 = k × 4² = 16k ( divide both sides by 16 )

1.5 = k

y = 1.5R² ← equation of proportion

When y = 1350 , then

1350 = 1.5R² ( divide both sides by 1.5 )

900 = R² ( take the square root of both sides )

[tex]\sqrt{900}[/tex] = R , that is

R = 30

Alex paid 108.34 for groceries. Rounded to the nearest dollar, how did alex pay for groceries?​

Answers

108.34 rounded to the nearest dollar is 108

The rounded figure of the amount Alex paid at the groceries shop is $108.

What is rounding a figure?

The process of replacing a number by another number of approximately the same value but having fewer digits is called rounding a figure.

Given that, Alex paid 108.34 for groceries. We need to round it to the nearest dollar,

We know that,

If the first decimal digit is 5 or more, we increase the whole part by one unit. For example, $34.57 rounded to the nearest whole dollar is $35.

If the first decimal digit is less than 5, we leave the whole part as it is. For example, $45.19 rounded to the nearest dollar is $45.

Here, the first decimal point is less than 5, therefore, we will leave the whole part as it is.

Hence, the rounded figure of the amount Alex paid at the groceries shop is $108.

Let the number be (10 x + y)

Then, 10 x + y = 3 * (x + y) (given)

Or, 10 x + y = 3 x + 3 y

Or, 10 x - 3 x = 3 y - y

Or, 7x = 2 y

Or, x = 2 y / 7 ( Eq. 1)

Also, 10 x + y + 45 = 10 y + x ( given)

Or, 10 x - x = 10 y - y - 45

Or, 9 x = 9 y - 45 ( Eq. 2)

Substituting the value of x from (Eq. 1) in (Eq. 2), we have:

9 * 2 y / 7 = 9 y - 45

Or, (9 y ) - (18 y / 7) = 45

Or, 63 y - 18 y = 315

Or, 45 y = 315

Or, y = 7

From (Eq. 1),

x = 2 * 7 / 7 = 2

So, the number is 10 x + y = (10 * 2) + 7 = (20 + 7) = 27

Answer

Check:

Sum of the digits = 2 + 7 = 9

9 * 3 = 27 ✓

Adding 45 to the number 27, we get 72. So, the digits get reversed.

2500 dollars is placed in an account with an annual interest rate of 7.25%. To the nearest year, how long will it take for the account value to reach 13100 dollars?
please help!^^

Answers

Answer:

about 58 years 6 months

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 7.25%/100 = 0.0725 per year,

then, solving our equation

t = 10600 / ( 2500 × 0.0725 ) = 58.4828

t = 58.4828 years

The time required to

accumulate simple interest of $ 10,600.00

from a principal of $ 2,500.00

at an interest rate of 7.25% per year

is 58.4828 years (about 58 years 6 months).

Answer:

5 years

Step-by-step explanation:

Find out how much you earn a year from interest and money.

Find 1%.

100% = 2500

1% = 2500 ÷ 100 = 25

7.25% = 25 x 7.25 = 181.25

2500 + 181.25 = 2681.25

Now divide how much you earn from money and interest from 13100.

13100 ÷ 2681.25 = 4.88

4.88 estimated to 5
