Currently, Mike is 8 years more than twice Tom's age. In 3 years from now,
Mike's age
will be three times Tom's age. What are their current ages?

Answers

Answer:

The current age of Mike is 12 years old while that of Tom is 2 years old.

Step-by-step explanation:

Let the current age of Mike be m years old and that of Tom be t years old.

Currently

m= 2t +8

3 years from now

Tom's age= t +3

Mike's age

= m +3

= 2t +8 +3

= 2t +11

Given that in three years, Mike's age is 3 times Tom's age,

2t +11= 3(t +3)

Expand:

2t +11= 3t +9

3t -2t= 11 -9

t= 2

Current age of Mike

= 2t +8

= 2(2) +8

= 4 +8

= 12

Bella has joined a new gym in town. The cost of membership is $25 per month. The after-hours policy at the gym allows her to work out late at night for an extra fee of $4 per visit. If Bella's first monthly bill totaled $53, which equation can be used to determine how many times Bella worked out after hours?​

Answers

Answer:

So, we get

$25+4n = $53 is the required equation.

Therefore, $25+4n = $53  equation can be used to determine how many times Bella worked out after hours.

Step-by-step explanation:

The total monthly bill of the gym = $53

The cost of membership of a month = $25

Let 'n' be extra the number of hours Bella worked on.

The cost for working on extra hours = $4

So, we have to determine the equation, Bella worked out after hours.

We will determine the equation by:

(Monthly cost of membership) + ( cost for extra hours  number of hours extra worked on )  = Total monthly bill received

Tom wants to borrow $16,578 for a car. The bank is going to charge him 12% interest annually, compounded monthly. If his car payment is $345.00 a month. How much will he owe at the end of 4 months? (Take this one month at a time. Determine the interest for the month; add it to the principal. Then subtract the payment, and that is your new principal for the next month.)​

Answers

Answer:

Step-by-step explanation:

Principal, P = $16,578

Interest rate, r = 12% = 0.12

Monthly interest rate = annual interest rate / 12

= 12%/12

= 1%

= 0.01

Time, t = 1 year

Number of period, n = 12

Car payment per month = $345.00

Month 1:

A = P(1 + r/n)^nt

A = 16,578(1 + 0.01/12)^(12)(1)

A = 16,578(1 + 0.000833333)^(12)

= 16578(1.000833333)^12

= 16578(1.0100459608871)

A = $16,744.54

Principal after month 1 repayment = $16,744.54 - $345

= $16,399.54

Month 2:

A = P(1 + r/n)^nt

= $16,399.54(1 + 0.01/12)^(12)(1)

= 16,399.54(1 + 0.000833333)^(12)

= 16,399.54(1.000833333)^12

= 16399.54(1.0100459608871)

= 16,564.289137406431934

= $16,564.29

Principal after month 2 repayment = $16,564.29 - $345

= $16,219.29

Month 3:

A = P(1 + r/n)^nt

= $16,219.29(1 + 0.01/12)^(12)(1)

= 16,219.29(1 + 0.000833333)^(12)

= 16,219.29(1.000833333)^12

= 16219.29(1.0100459608871)

= 16382.228352956532159

= $16,382.23

Principal after month 3 repayment = $16,382.23 - $345

= $16,037.23

Month 4:

A = P(1 + r/n)^nt

= $16,037.23(1 + 0.01/12)^(12)(1)

= 16,037.23(1 + 0.000833333)^(12)

= 16,037.23(1.000833333)^12

= 16037.23(1.0100459608871)

= 16198.339385317426733

= $16,198.34

Principal after month 4 repayment = $16,198.34 - $345

= $15,853.34

The correct option is D.

What is a polynomial?

An expression that consists of variables, constants, and exponents that are combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

We can use polynomial long division to find the remainder of (x³ + 1) divided by (x² - x + 1):

                 x + 1

                 -------------

x² - x + 1 | x³ + 0x² + 0x + 1

              - (x³ - x² + x)

               ---------------

                      x² - x + 1

                   - (x² - x + 1)

                      -------------

                      0

Therefore, the remainder when (x³ + 1) is divided by (x² - x + 1) is 0.

A taxi travels for 126 km from Seremban taxi station at 9:15 morning and reach the Shah Alam taxi station at 10:45 morning. Calculate the average speed, in km h, of the whole journey of the taxi.​

Answers

Given:

Taxi travels for 126 km.

Starting time = 9:15

Reaching time = 10:45

To find:

The average speed, in km/h.

Solution:

We have,

Distance = 126 km

Time = 9:15 to 10:45

        = 1 hour 30 minutes

        = 1.5 hour                        [1 hour = 60 minutes]

We know that,

[tex]Speed=\dfrac{Distance}{Time}[/tex]

[tex]Speed=\dfrac{126}{1.5}[/tex]

[tex]Speed=84[/tex]

Therefore, the average speed to the taxi is 84 km/h.

Answers

Answer:

Step-by-step explanation:

Mean

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Median

Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2.

Mode

To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
