What is the total cost of a new car that has a price of $24,000 and a sales tax rate of 9%?

Answers

Answer:

26,160.00

Step-by-step explanation:

24,000 + 9% = 26,160.00

Have a wonderful day! Dream a good dream of good people. :)

Answer:

The answer is

$26,160

Step-by-step explanation:

In this problem, it says that the total cost of the new car is the price of $24,000 plus a sales tax of 9%. For the problem, it's obvious to use addition, because when you buy something, most of the time they add taxes.

So,

24,000

+ 9%

‾‾‾‾‾‾‾‾‾‾

26,160

Therefore, 26,160 is the correct answer for your problem.

The amount of a radioactive substance remaining after t years is given by the function f(t) = m(0.5)", where m is the
initial mass and h is the half-life in years. Cobalt-60 has a half-life of about 5.3 years. Which equation gives the
mass of a 50 mg Cobalt-60 sample remaining after 10 years, and approximately how many milligrams remain?

Answers

Using an exponential function, it is found that the equation is:

[tex]f(1.8868) = 60(0.5)^{1.8868}[/tex]

Which means that approximately 16.22 mg remain.

What is an exponential function?

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

A(0) is the initial value.r is the decay rate, as a decimal.

In this problem, the equation is:

[tex]f(h) = m(0.5)^h[/tex]

We work with a 50 mg Cobalt-60 sample, hence m = 60, and considering a half-life of 5.3 years, in 10 years we have h = 10/5.3 = 1.8868. Hence the equation is:

[tex]f(1.8868) = 60(0.5)^{1.8868} = 16.22[/tex]

Approximately 16.22 mg remain.

two terms of an arithmetic sequence are a10=16 and a35=66 find the sum of the first 75 terms

Answers

The sum of the first 75 terms of the arithmetic sequence that has 10th term as 16 and the 35th term as 66 is 5400.  

How to find the sum of terms using Arithmetic sequence formula

aₙ = a + (n - 1)d

where

a = first termd = common differencen = number of terms

Therefore, let's find a and d

a₁₀ = a + (10 - 1)d

a₃₅ = a + (35 - 1)d

Hence,

16 = a + 9d

66 = a + 34d

25d = 50

d = 50 / 25

d = 2

16 - 9(2) = a

a = 16 - 18

a  = -2

Therefore, let's find the sum of 75 terms of the arithmetic sequence

Sₙ = n / 2 (2a + (n - 1)d)

S₇₅ = 75 / 2 (2(-2) + (75 - 1)2)

S₇₅ = 37.5 (-4 + 148)

S₇₅ = 37.5(144)

S₇₅ = 5400

y = -2

y intercept = -2

For x intercept, plug 0 for y

(0) = -x - 2

Move -2 to other side

2. Find the length of the missing side:

Answers

Answer:

1. Area of sector is 14.14 sq.m

2. Length of the missing side is 10 cm

Step-by-step explanation:1.)

Using formula:

Area of sector = θ/360° × π r²

Where,

θ = 45° Radius (r) = 6m

Substituting the required values:

→ Area = 45°/360° × 22/7 × (6)²

→ Area = 0.125 × 22 × 36/7

→ Area = 2.75 × 36/7

→ Area = 99/7

→ Area = 14.14 sq.m

2.)

In given right angled traingle:

Perpendicular = 6 cmBase = 8 cmHypotenuse = ?

Using Pythagoras theorem,

(H)² = (B)² + (P)²

where,

H is hypotenuseB is Base P is perpendicular

Substituting the required values:

→ (Hypotenuse)² = (8)² + (6)²

→ (Hypotenuse)² = 64 + 36

→ (Hypotenuse)² = 100

→ Hypotenuse = √100

→ Hypotenuse = 10 cm

Hence,

Hypotenuse of Traingle is 10 cm

There are books of three different languages on the bookshelves of one section of a library. The three different languages are Chinese, Malay and Tamil. Chinese books make up
6/10
of the books. The number of Malay books is 7 times more than the number of Tamil books. If there are 56 Malay books, how many books are there altogether in this section of the library?

Answers

Answer:

There are 160 books in this section of the library

Step-by-step explanation:

to solve this problem you need to set up a ratio.

since there are 7 times Malay books the number of Tamil books, you can say that

x = # of Tamil books

7x = # of Malay books

next, you know that there are 56 Malay books so you can substitute.

7x = 56

x = 56/7

x = 8

x = # of Tamil books

8 = # of Tamil books

now you know that there are 56 Malay books and 8 Tamil books. Chinese books make up 6/10 of the library so the other languages must add up to 4/10 of the books.

56 + 8 = 4/10 of the total books

64 = 4/10 of total books

if you call the total books T you can make this equation:

64 = 4/10T

64 * 10/4 = T

160 = T
