Look at the middle 7 in the decimal 0.777. How is its value related to the value of the 7 to its left? To the value of the 7 to its right?

Answers

Answer:

Value of middle 7 = [tex]\frac{1}{10}[/tex](value of 7 to the left of the middle 7)

Value of middle 7 = [tex]10[/tex](value of 7 to the right of the middle 7)

Step-by-step explanation:

7 in the middle of number [tex]0.777[/tex] is equal to [tex]\frac{7}{100}[/tex]

7 to the left of the middle 7 is equal to [tex]\frac{7}{10}[/tex]

So,

[tex]\frac{7}{100}=(\frac{1}{10}) \frac{7}{10}[/tex]

That is value of middle 7 = [tex]\frac{1}{10}[/tex](value of 7 to the left of the middle 7)

Also,

7 to the right of the middle 7 is equal to [tex]\frac{7}{1000}[/tex]

So,

[tex]\frac{7}{100}=(10) \frac{7}{1000}[/tex]

That is value of middle 7 = [tex]10[/tex](value of 7 to the right of the middle 7)

The recommended storage temperature for a certain type of squash is 10°C to 13°C. Which inequality
represents the possible storage temperatures F (in degrees Fahrenheit) of the squash.

Answers

Answer:

The simultaneous inequation representing the recomended storage temperature is:

[tex]50\,^{\circ}F \leq T \leq 55.4\,^{\circ}F[/tex]

Step-by-step explanation:

In this case, the statement must be represented mathematically by a simultaneous inequation, in which temperature must be equal to or greater than 10 ºC, expressed in Fahreheit degrees, and equal or less than 13 ºC, expressed in Fahrenheit degrees.

Bounds can be converted into Fahrenheit degrees from Celsius degrees:

[tex]T_{F} = \frac{9}{5} \cdot T_{C}+32\,^{\circ}F[/tex] (Eq. 1)

Where:

[tex]T_{C}[/tex] - Temperature, measured in Celsius degrees.

[tex]T_{F}[/tex] - Temperature, measured in Fahrenheit degrees.

Lower bound ([tex]T_{C} = 10\,^{\circ}C[/tex])

[tex]T_{F} = \frac{9}{5}\cdot (10\,^{\circ}C) + 32\,^{\circ}F[/tex]

[tex]T_{F} = 50\,^{\circ}F[/tex]

Upper bound ([tex]T_{C} = 13\,^{\circ}C[/tex])

[tex]T_{F} = \frac{9}{5}\cdot (13\,^{\circ}C) + 32\,^{\circ}F[/tex]

[tex]T_{F} = 55.4\,^{\circ}F[/tex]

The simultaneous inequation representing the recomended storage temperature is:

[tex]50\,^{\circ}F \leq T \leq 55.4\,^{\circ}F[/tex]

Answers

Answer:

C. A loan finances the total purchase price of the car while a lease finances only the depreciated value and related fees

Step-by-step explanation:

He legit said it. (Just writing this for those who are blind)

One difference between obtaining a car with a lease or a loan is that: a loan finances the total purchase price of the car while a lease finances only the depreciated value and related fees.

What is the difference between a Loan and a Lease?

A loan is suitable for a property that you wish to possess at the maturity date, i.e. anything with long-term worth.

On the other hand, a lease is ideal for items that deteriorate gradually and will not retain their worth beyond the period.

The most significant contrast between a lease and a loan is the manner in which the finance costs are paid.

The interest on a loan is amortized throughout the period. i.e. your consumer pays more interest at the start and more principal in the end.

Although leasing is not free, the financing charges are predetermined all through the period and are not deducted from the borrowed amount.

From the information given:

One difference between obtaining a car with a lease or a loan is that: a loan finances the total purchase price of the car while a lease finances only the depreciated value and related fees.

URGENT!!!!!! Find the value of q in the following system so that the solution to the system is——

Answers

Answer:  Q = 8

====================================================

Explanation:

The left hand side of the first equation is x-3y

The left hand side of the second equation is 2x-6y = 2(x-3y). Note how it's simply double of the first expression x-3y

If we multiply both sides of the first equation by 2, we get

x-3y = 4

2(x-3y) = 2*4

2x-6y = 8

Meaning that 2x-6y = 8 is equivalent to x-3y = 4. Both produce the same line leading to infinitely many solutions. Each solution will lay along the line x-3y = 4.

We can say each solution is in the set {(x,y): x-3y = 4}

Which is the same as saying each solution is of the form (3y+4,y)

What is the sum total of 2.36 cm, 5.298 cm, and 5.53 cm, using significant digits?

Answers

Answer:

13.19

Step-by-step explanation:

The sum total of 2.36 cm, 5.298 cm, and 5.53 cm, using significant digits is 13.19cm

The numbers in the question are decimals. Decimals are made up of writing integers and non integers. They are made up of tens, hundreds, tenths and hundredths.

For example, the decimal 2.36, is made up of unit (2), tenths (2) and hundredths (6).

In order to determine the sum of the decimals given, add 2.36, 5.298 and 5.53 together.

2.36 + 5.298  + 5.53 = 13.188 cm

Use the graph to determine which statement describes f(x).

Answers

Answer:

The statements are not provided, so let's do a complete description of f(x)

In the graph, we can see two asymptotes at x = 1.

This means that the denominator is equal to 0 when x = 1, then we can write:

f(x) = A/(x - 1)

Where we can start thinking that A is a constant.

Now we also can see that when x = 2, f(2) is equal to 1, or:

f(2) = 1.

Then:

f(2) = 1   = A/(2 - 1) = A/1

Then we have  A = 1.

Then our function is:

f(x) = 1/(x - 1)
