Answer:

0 = − 1 /6

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

To find the value of x, we first find the fraction that is equivalent to 1/3 that has a denominator of 12.

Multiplying or dividing the numerator and denominator of

a fraction by the same number will give us an equivalent fraction.

So if we multiply both the numerator and denominator of

the first fraction by 4, we can see that 1/3 = 4/12.

So the value of x must be 4.

*PLEASE HURRY WILL GIVE BRAINLY* A company's profits (in dollars) are modeled by the function p(x) = —x^2+ 1100x - 300000, where x is the number of units produced. To determine the minimum number

of units that must be produced in order to earn profits of $590, the company plots the parabola of y = —x^2 1100x -- 300000 and the line x = 590, finds the intersection

of the two, and concludes that 900 units must be produced. Is the company correct? Explain, rounding values to the nearest whole number if necessary.

Answers

No, it’s not correct. The y-axis on the graph represents the profits p(x) so the minimum number of units produced should be when the a horizontal line at y = 590 first intersects the parabola drawn left to right, and not a vertical line at x = 590 because that represents the profit as 590 units are produced.

On that date, 77.65 dollars is worth 3,870.08 rupees.

On that date, 82.12 rupees is worth  $1.65.

What is the worth of the currencies?

Exchange rate is the rate at which one currency is exchanged for another currency.

In order to convert rupees to dollars, multiply the value of the rupees by the exchange rate:

value of the rupees x exchange rate

77.65 to rupees = 77.65 x 49.84 = 3,870.08 rupees

In order to convert dollars to rupees, divide the value o the dollars by the exchange rate:

value of the dollars / exchange rate

82.12 to dollars = 82.12 / 49.84 = $1.65

The 6 elephants at the zoo have a combined weight of 11,894 pounds. About how much does each elephant weigh?

Answers

Answer:

1982.33 pounds

Step-by-step explanation:

If they all weigh the same amount then you can figure it out by division.

11894/6=1982.33

Answer:

TO find out how much each elephant weighs you simply have to do 11, 894 divided by 6. Since the answer is a decimal (1982.33333333), I would just round it to the nearest tenth as it dosent specify where we have to round it to. SO, 1982.33333333 rounded to the nearest tenth is 1982.3

If 134n = 54eight , calculate n​

Answers

sorry what does 54eight mean?

The value of 'n' is approximately 4.0896.

To calculate the value of 'n' in the equation 134n = 548, we can isolate 'n' by dividing both sides of the equation by 134.

134n = 548

Dividing both sides by 134:

n = 548 / 134

Evaluating the division:

n ≈ 4.0896

Therefore, the value of 'n' is approximately 4.0896.

If there are four black kittens and two orange kittens how does the number of orange kittens compared to the total number of kittens in the litter write a comparison beginning with for every?

Answers

Answer:

For every two black kittens, there is one orange kitten.

Step-by-step explanation:

Simplify the ratio and put it in word form.

Answer:

For every three kittens there is one orange kitten

Step-by-step explanation:

The total number of kittens is equal to four black kittens + two orange kittens, which makes for six kittens.

So for every six kittens there are two orange kittens.

We can simplify this down further by dividing by the greatest common factor, 2.

So,

For every three kittens there is one orange kitten.

The simplified expression is 7x- 2.

What is Expression?

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

−4x−2y+6 from 3x−2y+4.

So, subtraction will be as follows

3x - 2y + 4-( -4x  -2y + 6 )

or, 3x - 2y + 4  + 4x + 2y -6

or, 7x - 2

Hence, the simplified expression is 7x- 2.
