a fraction that is a repeating decimal between 0.5 and 1

Answers

The fraction [tex]\( \frac{2}{3} \)[/tex] results in a repeating decimal [tex]\( 0.\overline{6} \)[/tex], which falls between 0.5 and 1.

Sure, here's a step-by-step explanation:

1. Start with the fraction: We begin with the fraction [tex]\( \frac{2}{3} \)[/tex].

2. Convert to decimal: To convert this fraction to a decimal, divide the numerator (2) by the denominator (3).

[tex]\[ \frac{2}{3} = 0.66666... \][/tex]

The decimal representation of [tex]\( \frac{2}{3} \) is \( 0.\overline{6} \)[/tex], which means the digit 6 repeats infinitely.

3. Determine where it falls between 0.5 and 1: Since the decimal [tex]\( 0.\overline{6} \)[/tex] is greater than 0.5 and less than 1, the fraction [tex]\( \frac{2}{3} \)[/tex] indeed fits the criteria of being a fraction with a repeating decimal between 0.5 and 1.

For any two integers a and b, (a + b)2 = a? + b2

Answers

Answer:

(a+b)2 = a2 + b2

Step-by-step explanation:

Answer:

[tex](a+b)^2=a^2+2ab+b^2[/tex]

Step-by-step explanation:

We have been given an incomplete statement [tex](a+b)^2=a?+b^2[/tex]. We are supposed to complete the given statement.

We can see that left side of our given equation represents a perfect square. The right side of equation would be perfect square trinomial.

Let us use perfect square formula to expand our given perfect square as:

[tex](x+y)^2=x^2+2xy+y^2[/tex]

Substitute [tex]x=a[/tex] and [tex]y=b[/tex]:

[tex](a+b)^2=a^2+2ab+b^2[/tex]

Therefore, the complete statement would be [tex](a+b)^2=a^2+2ab+b^2[/tex].

It costs $2.55 to make a sandwich at the local deli shop. To make a profit, the deli sells it at a price that is 140% of the cost. The sandwich sells for $___. (Make sure to enter the answer as a decimal number only. Do not enter special characters such as the dollar symbol

Answers

Answer:

$3.57

Step-by-step explanation:

You multiply .40 by 2.55 which gives you 1.07 then you add that to the original

Answer:

3.57 dollars

Step-by-step explanation:

Cost of sandwich = $2.55

We are given that  To make a profit, the deli sells it at a price that is 140% of the cost

So, selling price of sandwich = [tex]140\% \times 2.55[/tex]

                                             = [tex]\frac{140}{100} \times 2.55[/tex]    

                                             = [tex]3.57[/tex]    

Hence The sandwich sells for 3.57 dollars

Use the point-slope formula to write an equation of the line that passes through (-5,3) and
(4,6). Write the answer in slope-intercept form (if possible).

Answers

Answer:

The equation in point slope form is [tex]y-6=\frac{1}{3}(x-4)[/tex]

The equation in slope intercept form is [tex]y=\frac{1}{3}x-\frac{14}{3}[/tex]

Step-by-step explanation:

step 1

Find the slope m

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have

[tex](-5,3),(4,6)[/tex]

Substitute the values

[tex]m=\frac{6-3}{4+5}[/tex]

[tex]m=\frac{3}{9}[/tex]

simplify

[tex]m=\frac{1}{3}[/tex]

step 2

Find the equation of the line in point slope form

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=\frac{1}{3}[/tex]

[tex](4,6)[/tex]

substitute

[tex]y-6=\frac{1}{3}(x-4)[/tex] ---> equation in point slope form

step 3

Find the equation of the line in slope intercept form

[tex]y=mx+b[/tex]

[tex]y-6=\frac{1}{3}(x-4)[/tex] ----> convert to slope intercept form

[tex]y-6=\frac{1}{3}x-\frac{4}{3}[/tex]

[tex]y=\frac{1}{3}x-\frac{4}{3}+6[/tex]

[tex]y=\frac{1}{3}x-\frac{14}{3}[/tex]

Which answer is the equation of the line?

a. -x+y=12
b. -3x+y=4
c. -3x + y = 16
d. -x+y=8

Answers

Answer:

d. -x + y = 8

Step-by-step explanation:

First find the rate of change [slope]:

-y₁ + y₂\-x₁ + x₂ = m

[tex]\frac{-7 + 10}{1 + 2} = \frac{3}{3} = 1[/tex]

Then, we can go ahead and use the Slope-Intercept Formula instead of the Point-Slope Formula because you get it done swifter. It does not matter which ordered pair you choose:

10 = 1[2] + b

2

8 = b

y = x + 8 >> Line in Slope-Intercept Form

Since the exercise wants the equation in Standard Form:

y = x + 8

-x -x

________

-x + y = 8 >> Line in Standard Form

__________________________________________________________

7 = 1[-1] + b

-1

8 = b

y = x + 8 >> Line in Slope-Intercept Form

y = x + 8

-x -x

________

-x + y = 8 >> Line in Standard Form

** You see? I told you it did not matter which ordered pair you chose because you will always get the exact same result, plus the fact that I told you it was alot swifter than the Point-Slope Formula.

* Tip: Use the Point-Slope Formula when it tells you to, otherwise keep using the Slope-Intercept Formula. That way, you get your work done in a jip!

A group of ten 6- and 12-volt batteries are wired in series. The sum of their voltages is 84 volts. How many of each type of battery are used?

Answers

...... I need this as well please help us!!!

Final answer:

The problem involves creating two linear equations based on the given information and then solving them simultaneously to find that there are six 6-volt batteries and four 12-volt batteries among the ten.

Explanation:

Solving the Battery Voltage Problem

To solve the problem, we will use a system of linear equations. Let's denote the number of 6-volt batteries as x and the number of 12-volt batteries as y. Since there are ten batteries in total, we can write the following equation:

1. x + y = 10 (Equation for the total number of batteries)

The sum of voltages of all batteries is given to be 84 volts. Each 6-volt battery contributes 6 volts and each 12-volt battery contributes 12 volts to the total voltage. We can write the second equation for the sum of the voltages:

2. 6x + 12y = 84 (Equation for the total voltage from the batteries)

To find the values of x and y, we can simplify the second equation:

3. Divide the second equation by 6:

x + 2y = 14

Now we can subtract the first equation from this new equation to find the value of y:

4. (x + 2y) - (x + y) = 14 - 10

5. y = 4

Now that we know there are four 12-volt batteries, we can use the first equation to find the number of 6-volt batteries:

6. x = 10 - y

7. x = 10 - 4

8. x = 6

Therefore, the group consists of six 6-volt batteries and four 12-volt batteries.

Which of the following is an equation of the circle in
the xy-plane that has center (0,0) and radius 4?
A) x2 + y2 = 4
B) x2 + y2 = 8
C) x2 + y2 = 16
D) x2 + y2 = 64​

Answers

Answer:

C

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ← where r is the radius

here r = 4, thus

x² + y² = 4², that is

x² + y² = 16 → C

Answer:

C). x^2 + y^2 = 16.

Step-by-step explanation:

The equation of a circle with  center (0, 0) and radius r is

x^2 + y^2 = r^2

So our equation  (with r = 4) is:

x^2 + y^2 = 4^2

x^2 + y^2 = 16.

two numbers have a sum of 24. if one number is P, express the other number in terms of P

Answers

Say the other number is a. The sum is a+P, which also equals 24.

Write it as, a+P=24.

Now subtract P from both sides.

you get, a = 24-P

So, the other number in terms of P is 24 - P

To express the other number in terms of P when the sum of the two numbers is 24, subtract P from 24: Q = 24 - P.

In Mathematics, when you have a sum of two numbers, and you know the value of one number, you can find the other number by subtracting the known number from the total sum.

This is known as solving for a variable.

In this specific question where two numbers have a sum of 24, and if one number is P, the other number can be expressed in terms of P as 24 - P.

It is a simple equation derived from the basic formula: Sum = Number1 + Number2

Write the equation of the line perpendicular to y= -1/2x - 5 through the point (1,-4)

Answers

Answer:

y = 2x - 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{2}[/tex] x - 5 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2, thus

y = 2x + c ← is the partial equation of the line

To find c substitute (1, - 4) into the partial equation

- 4 = 2 + c ⇒ c = - 4 - 2 = - 6

y = 2x - 6 ← equation of line
