Simplify 0.1+3.7+5.9

Step-by-step explanation:

her ratio is therefore 25/10, which can be also written as 5/2, because ratios are just a special form of fractions.

to find how many labels she can type in 1 hour, we need to find the rehashing between 10 minutes and 1 hour.

1 hour = 60 minutes.

60 minutes = 6 × 10 minutes.

so, to find the equivalent ratio based on 1 hour, we need to multiply the denominator (bottom part) by 6.

and to keep the ratio value we need to multiply the numerator (top part) by the same number :

25/10 × 6/6 = 150/60

and since the ratio is always telling us how many labels can be typed per unit of time, we see,

she can type 150 labels in 1 hour (60 minutes)

The answer is 127.5146314631

What is 87.65 decimal in octal? 87.65 from decimal to octal is 127.5146314631. Here we show you how to write 87.6510 in octal and how to convert 87.65 from base-10 to base-8.

To convert decimal number 87.65, we convert its integer and fraction part individually and then add them to get the equivalent octal number, as below:

To convert integer 87 to octal, follow these steps:

Divide 87 by 8 keeping notice of the quotient and the remainder. Continue dividing the quotient by 2 until you get a quotient of zero.

Then just write out the remainders in the reverse order to get the equivalent octal number.

87 / 8 = 10 with remainder 7

10 / 8 = 1 with remainder 2

1 / 8 = 0 with remainder 1

Here is the answer to 87 decimal to octal number:

127

For converting decimal fraction 0.65 to octal number, follow these steps:

Multiply 0.65 by 8 keeping notice of the resulting integer and fractional part. Continue multiplying by 8 until you get a resulting fractional part equal to zero (we calcuclate upto ten digits).

Then just write out the integer parts from the results of each multiplication to get equivalent octal number.

0.65 × 8 = 5 + 0.2

0.2 × 8 = 1 + 0.6

0.6 × 8 = 4 + 0.80000000000001

0.80000000000001 × 8 = 6 + 0.40000000000009

0.40000000000009 × 8 = 3 + 0.20000000000073

0.20000000000073 × 8 = 1 + 0.60000000000582

0.60000000000582 × 8 = 4 + 0.80000000004657

0.80000000004657 × 8 = 6 + 0.40000000037253

0.40000000037253 × 8 = 3 + 0.20000000298023

0.20000000298023 × 8 = 1 + 0.60000002384186

Here is the answer to 0.65 decimal to octal number:

0.5146314631

Therefore, decimal number 87.65 converted to octal is equal:127.5146314631

It will take 10.3 years for the account to contain $3000.

The formula to be used is given as follows :

              A(t) = a ( 1 + r )^t      (1)

where,  A(t) = future value

               a = principal amount or amount initially deposited.

               r = annual interest rate

               t = time

According to the question we have been given that

            a = $2000

            r = 0.04

            A(t) = $3000

putting the required values in equation (1) we get

          3000 = 2000(1+0.04)^t

          1.5 = (1.04)^t

Taking log both sides we get

    log(1.5) = t log(1.04)

       0.176 = t *0.017

       t = 10.3 years.

Thus it takes 10.3 years for the account to contain $3000.

Step-by-step explanation:

We get the value of h(1) × g(1) as - 14 for the functions g (x) = x - 3 and h (x) = x² + 6.

We are given the two functions as:

g (x) = x - 3 and h (x) = x² + 6

Now, we will first find h (1)

h (1) = (1)² + 6

h(1) = 1 + 6

Add them, we get:

h (1) = 7

Now, we will find g (1):

g (1) = 1 - 3

g (1) = - 2

Now we will find the expression  h(1) × g(1):

h(1) × g(1) = 7 × ( - 2 )

h(1) × g(1) = - 14

Therefore, we get the value of h(1) × g(1) as - 14 for the functions g (x) = x - 3 and h (x) = x² + 6.

The inverse function returns the original value for which the output of a function was given.

The value of  f(x) = 10x - 10 is -110.

The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.

An inverse in mathematics is a function that serves to "undo" another function. That is, if f(x) produces y, then putting y into the inverse of f yields x. Invertible functions are those that have an inverse, which is denoted by f1.

Lett the function be F(x) = 10x - 10

To differentiate with respect to X

F⁻¹(x) = 10

F( f⁻¹(x)) = F(10)

F( f⁻¹(x)) = -10x -10

Substitute the value of X = 10, then we get

F( f⁻¹(x)) = -10(10)-10

simplifying the above equation, we get

F( f⁻¹(x)) = -100-10

F( f⁻¹(x)) = -110

Therefore, the value of (f ⁰ f⁻¹)(d) = -110.

The cost of each ticket for the ballet is $13.25.

The cost price or simply the cost in retail systems represents the particular value that corresponds to the unit price paid. In some stock market theories, this value is utilized to establish the value of stock holdings and is used as a key determinant of profitability.

There are numerous ways to calculate cost pricing, however it all relies on the kind of query we are asking. For instance,

If a selling price and profit are provided, then,

Cost price = Selling price (SP) − profit

If a selling price and loss are provided, then,

Cost price =Selling price + loss

In the given question,

The total amount that Marta paid is $53

=> amount = $53

and total number of tickets = 4

Now, the cost of each ticket = Total amount / number of tickets

                                               = $53 / 4

                                               = $ 13.25

Answer:

4x - 5 = 131 where x is the first number.

Step-by-step explanation:

Let the first number be x.

Seconder number = 2x + 7.

Third number = x - 12.

So, the equation is :-

x + 2x + 7 + x - 12 = 131

4x - 5 = 131

4x = 136

x = 34

First number = 34, second = 2(34) + 7 = 75 and third number = 34-12 = 22.

The surface area is the sum of the area of the surfaces. The surface area of the box is 360x^2 - 216x

The formula for calculating the surface area of a box is expressed according to the equation:

Surface area = 2(lw + wh +lh)

Given the following parameters

length = 6x

width = 12x - 9

height = 6x

Substitute

Surface area = 2(6x(12x-9) + (12x-9)(6x) +(6x)(6x))

Expand

Surface area = 2(72x^2-54x) + (72x^2-54x) + 36x^2)

Surface area = 2(180x^2-108x)

Surface area = 360x^2 - 216x

The inverse of the given equation is  r = (10D - 5)/11 which represents the reaction speed of the car in terms of the reaction distance.

The car travels a distance of D feet, where D is a function of the speed r miles/hour given by D(r) = (11r + 5)/10

D = (11r + 5)/10

⇒ 10D = 11r +5         (multiply by 10 on both sides)

⇒ 10D - 5 = 11r         (subtracting 5 on both sides)

⇒ (10D - 5)/11 = r      (dividing by 11 on both sides)

Therefore, the inverse of the given equation is r = (10D - 5)/11.

Inverse represents the speed of the car (miles/hour) in terms of the reaction distance D.

The inverse is also a function, which represents the reaction speed of the car in terms of the reaction distance.

An expression that can be used to determine the total amount of credit cards opened at the two locations is: (a + b) (t) = 45 + 3t.

Given,

Number of credit cards opened at location a = a (t) = 20 + 4t

Number of credit cards opened at location b = b (t) = 25 - t

Hence,

Total amount of credit card:

(a + b) (t) = (20 + 4t) + (25 - t)

(a + b) (t) = 20 + 4t + 25 - t

(a + b) (t) = 45 + 3t

Also we can see that the base are same so we can use the property of logarithm in the given equation and we know that √2304 = 48. Thus replacing 48 by √2304.

Now solving this step by step using the properties of logarithm we get

                       [tex]=log_{4} \sqrt{2304} - \frac{1}{2} log_{4} 9 \\=\frac{1}{2} log_{4} 2304 - \frac{1}{2} log_{4} 9\\= \frac{1}{2} [log_{4} 2304 - log_{4} 9]\\= \frac{1}{2} [log_{4} (2304/9)]\\= \frac{1}{2} log_{4} 256\\= \frac{1}{2} log_{4} (4^{4} )\\= 2 * log_{4} 4\\= 2*1\\= 2[/tex]
