determine the quotient of 1 2/3 ÷ 4/5​

Answers

Answer 1

Answer:

The desired quotient is 25/12.

Step-by-step explanation:

Rewrite 1 2/3 as an improper fraction:  5/3.

Then divide this 5/3 by 4/5:

 5

------ ÷ 4/5

  3

It's easier (but completely correct) to invert the divisor (4/5) and then multiply 5/3 by (5/4):

  5       5       25

----- *  ----- = ------

  3        4       12

Step-by-step explanation:

during the week. Jimmy spent $45 eating out, gain $55 mowing lawns and spent $15 on gas. What was Jimmy’s change in dollars at the end of the week?

Answers

Answer:

5

Step-by-step explanation:

Let's look at the question.

Spent- He spent 45 dollars eating out.

He spent an additional 15 dollars on gas

Earned- He earned 55 dollars from mowing lawns

Earned is going to be a positive value.

Spent is going to be a negative value.

The situations don't matter in the context of the question. They are just asking how much he got charged.

The amount charged is always positive. You can never have a negative charged amount of money. That would mean the bank owed you money, which would never happen.

Let's substitute the values into an equation.

The variable C will stand for amount charged.

C = -45 + 55 - 15

Combine the negative values to get -60

Add -60 to 55.

You will get -5, which then you will have to take the absolute value of.

The absolute value will be the charge in dollars at the end of the week.

Jimmy’s change in dollars at the end of the week will be - 5 dollars.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Jimmy spent $45 eating out, gain $55 mowing lawns and spent $15 on gas.

Now,

Let the total amount Jimmy have = x

Since, Jimmy spent $45 eating out, gain $55 mowing lawns and spent $15 on gas.

Hence, After spent $45 on eating, we get;

The left amount = x - $45

And, After spent $55 on mowing lawns, we get;

The left amount = x - 45 + 55

                         = x + 10

And, After spent $15 on gas.

The left amount = x + 10 - 15

                         = x - 5

Thus, At the end of the week, he ended up with 5 dollars less than he started, so the change is -5 dollars.

Question 6 (1 point) If the area of a square is 121 square inches, what is the perimeter of the square? inches​

Answers

Answer:

  44 inches

Step-by-step explanation:

The side length is the square root of the area:

  A = s^2

  121 in^2 = s^2

  √(121 in^2) = s = 11 in

The perimeter of a square is 4 times the side length (since all four sides are the same length).

  P = 4s = 4(11 in) = 44 in

The perimeter of the square is 44 inches.

Question Given:

The area of a square is 121 square inches, what is the perimeter of the square? inches

Answer:

The perimeter = 44 inches

Explanation:

Area = 121 inches²

.°. Length of a side = √(121 inches²) = 11 inches

Now,

Perimeter of the square =

Length of a side×4

= 11 inches × 4

= 44 inches.

f×v= 13,573,692,509 if f stands for 5837 then what is v?

Answers

Answer:

              v = 2,325,457

Step-by-step explanation:

f×v= 13,573,692,509

5837×v= 13,573,692,509

v =  13,573,692,509÷5837

v = 2,325,457

Since F * V = 13,573,692,509
And F = 5837
Therefore, 5837 * V = 13,573,692,509
V = 13,573,692,509 / 5837
V = 2,325,457

How much is the bill for a person who uses 600 kWh in a month?
A. $70
ООО
B, $60
C. $40
D. $80

Answers

Answer:

$80

Step-by-step explanation:

If a person's monthly bill from the number of  kilowatt-hours (kWh), x is modeled by the equation b = 0.15(x - 200) +20, to know the bill for a person who uses 600 kWh in a month, we will substitute x = 600 into the modeled equation as shown;

[tex]b(x) = 0.15(x - 200) +20\\\\b(600) = 0.15(600 - 200) +20\\\\b(600 )= 0.15(400) +20\\\\b(600 )= 15/100*(400) +20\\\\b(600 )= (15*4)+20\\\\b(600 )= 60+20\\\\b(600 )= 80[/tex]

Hence the bill for a person who uses 600 kWh in a month is $80

       Barton:  2,130 watts/6 people=355 watts per person

       Stiles: 1,490 watts/2 people=745 watts per person

The Stiles family uses almost twice the amount of electricity per person than the other two families.  If you look at the calculations, you see that the other two families use within in about 350 to 400 watts of electricity per person, while this family uses about 750 watts per person.  350*2=700 and 400*2=800.  745 is a number almost in between both.

The Melendez family uses the least amount of water per person.  If you look at the calculations, this is the only family that uses less than 1,000 gallons of water per person, thus making them the family that uses the least amount of water per person.

Include the entire process for establishing a set of equations, the solution, and an explanation of what the solution means in terms of the variables. Complete your work in the space provided.

Answers

Step-by-step explanation:

Identify the variables (x,y) and represent them using the unknowns like this:

Let x represent the tens digit and y represent the ones digit of the number.

Relationships between the unknowns from the question:

x = 2y, and x + y = 12.

We can solve these simultaneous equations by substitution:

x + y = 2y + y = 12, 3y = 12, y = 4. So x = 8.

Explain why a quadratic equation with a positive discriminant has two real solutions, a quadratic equation with a negative discriminant has no real solution, and a quadratic equation with a discriminant of zero has one real solution.

Answers

Answer:

A quadratic equation can be written as:

a*x^2 + b*x + c = 0.

where a, b and c are real numbers.

The solutions of this equation can be found by the equation:

[tex]x = \frac{-b +- \sqrt{b^2 - 4*a*c} }{2*a}[/tex]

Where the determinant is D = b^2 - 4*a*c.

Now, if D>0

we have the square root of a positive number, which will be equal to a real number.

√D = R

then the solutions are:

[tex]x = \frac{-b +- R }{2*a}[/tex]

Where each sign of R is a different solution for the equation.

If D< 0, we have the square root of a negative number, then we have a complex component:

√D = i*R

[tex]x = \frac{-b +- C*i }{2*a}[/tex]

We have two complex solutions.

If D = 0

√0 = 0

then:

[tex]x = \frac{-b +- 0}{2*a} = \frac{-b}{2a}[/tex]

We have only one real solution (or two equal solutions, depending on how you see it)
