What is the quotient of 80 divided by 2/3

Answer:

Step-by-step explanation:

x - 3y = 10

5x + y = 2

x - 3y = 10

15x + 3y = 6

16x = 16

x = 1

5 + y = 2

y = -3

The order of operations (BODMAS) in mathematics and computer programming refers to a set of rules that represent standards for which operations to carry out first in order to evaluate a specific mathematical expression.

For instance, since the advent of contemporary algebraic notation, multiplication has been given a higher priority than addition in mathematics and most computer languages.

As a result, 1 + (2 × 3) = 7, rather than (1 + 2) × 3 = 9. is the value assigned to the expression 1 + 2 × 3. BODMAS was first used in the 16th and 17th centuries when addition and multiplication were given priority. BODMAS could only is used as a superscript to the right of their base.

The number of items that must be sold for the company to make a profit is 757.

Calulation of number of items sold:

R = 195x

C = 160x + 18000

Here R means the revenue

And, C means the cost

Now

We know that

Profit = R - C

Profit = Revenue - cost

=195x - (160x + 18000)

= 195x - 160x - 18000

= 35x -18000

Now solve the above equation

So,

35x - 18000 = 8500

x=757

Therefore,

x = 757

Using a system of equations, the expression, in terms of x, for the total number of students at the college is:

T = 11x.

A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem

For this problem, considering the Venn diagram, we have that:

Thus the total number of students in the college is given by:

T = A + B + x.

1/2 of the students who learn the piano also learn the guitar, hence:

A = x.

Thus the number of students who play the piano is:

A + x = x + x = 2x.

5 times as many students learn the guitar as learn the piano, hence:

B + x = 5(2x)

B + x = 10x

B = 9x.

Hence:

T = A + B + x

T = x + 9x + x

T = 11x.

The expression, in terms of x, for the total number of students at the college is:

If Brandon works at the waterpark on the weekends. Last Saturday, he worked 7 11/12 hours. On Sunday, he worked 84% of the hours he worked on Saturday, The total hours that he would have to work on the weekend is 6.65 hours

The total numbers of hours that was worked can be solved by

7 11/12 hours * 84%

= 95 / 12 * 84 / 100

= 7980 /1200

= 6.65

Therefore we can  say that if Brandon works at the waterpark on the weekends. Last Saturday, he worked 7 11/12 hours. On Sunday, he worked 84% of the hours he worked on Saturday, The total hours that he would have to work on the weekend is 6.65 hours

Answer:

6 hours and 39 minutes is the correct answer.

Step-by-step explanation:

So, set up your problem...

STEP 1: 84% out of 100%, or 84/100

STEP 2: 7 11/12 is a mixed number, so to make solving easier, make it an improper fraction: 95/12

- 7 11/12

- 7 × 12 = 84 + 11 = 95

- Keep the denominator (12)

- 95/12 is now an improper fraction.

STEP 3: Multiply 95/12 × 84/100 = 6.65

STEP 4: Convert to hours...

- Note that 6.65 hours and 6:65 is not the same. 6.65 hours with the decimal point is 6.65 hours in terms of hours. 6:65 with the colon is 6 hours and 65 minutes.

- Start by dividing up what is before and after the decimal point. 6 = hours, .65 = fractional hours

- To convert from 6.65 decimal hours to hours and minutes, we need to convert the .65 fractional hours to minutes.

- Since there are 60 minutes in an hour, you multiply the .65 fractional hours by 60 to get minutes. .65 × 60 = 39 minutes.

So, in conclusion, the correct answer to your question is... 6 hours and 39 minutes.

The length of DNA in Scientific notation (standard form) = 34[tex]e^{-8}[/tex] meters

Also, the significant figure in the measurement = 1

In this question, we have been given the length of human DNA.

The genetic information of almost every living thing is stored in a tiny strand called DNA.

Human DNA is 3.4 x 10-8 meter long.

We need to write the length in standard form.

3.4 x 10-8 meter

= 3.4 x 10 ^ (-8)

= 3.4 x 0.00000001

= 0.000000034

= 0.00000003

Here Significant Figures = 1

Decimals = 8

And the length in Scientific Notation = 34[tex]e^{-8}[/tex] meters

Part A: The equation of least squares regression line is

ŷ = 0.4684X + 64.69888

Part B: The residual that we have here is - 1.382

Part C: Residual refers to the difference between the observed value and the predicted value

Sum of X = 102.5

Sum of Y = 695

Mean X = 10.25

Mean Y = 69.5

Sum of squares (SSX) = 33.625

Sum of products (SP) = 15.75

Regression Equation = ŷ = bX + a

b = SP/SSX = 15.75/33.63 = 0.4684

a = MY - bMX = 69.5 - (0.47*10.25) = 64.69888

ŷ = 0.4684X + 64.69888

Residual = observed - predicted

The observed = 68

The predicted = 0.4684 x 10 + 64.69888

Answer:

Step-by-step explanation:

The value of x for given equation (2x - 20) /3 = 2x is x = -5

For given question,

we have been given an equation  2x minus 20 divided by 3 = 2x

i.e., (2x - 20) /3 = 2x

This equation models temperature change, where x represents the difference in degrees in the last 24 hours.

We need to solve given equation for x.

(2x - 20) /3 = 2x

(2x - 20)  = 3(2x)                ...........(Multiply by 3 on both sides)

2x - 20 + 20 = 6x + 20      ...........(Add 20 to both sides)

2x - 6x = 6x + 20 - 6x       ..........(Subtract 6x from both sides)

-4x = 20                            

x = -5                                  ..........(Divide by - 4 on both sides)

Therefore, the value of x for given equation (2x - 20) /3 = 2x is x = -5

Answer:

How far down the wall did

the ladder

Step-by-step explanation:

93.7 feet is the distance from the bottom of the slide to the bottom of the ladder.

Let us consider the distance from the bottom of the ladder to the bottom of the slide "x" (the unknown we want to find).

The ladder's length is 35 feet, and the slide's length is 100 feet.

According to the Pythagorean theorem:

c² = a² + b²

where c is the hypotenuse (the ladder's length), and a and b are the two other sides of the right-angled triangle (the distances we want to find).

In this case, the equation becomes:

35²= x² + 100²

Solving for x:

1225 = x² + 10000

x² = 10000 - 1225

x² = 8775

Taking the square root of both sides to find "x":

x = √8775

x = 93.7 feet

So, the distance from the bottom of the slide to the bottom of the ladder is 93.7 feet.

We are given the point X as:

X = ( - 2 , 5 )

We need to find the distance of X from the line p.

We will do this by using the distance formula:

Distance = √ (y₂ - y₁)² + (x₂ - x₁)²

Distance = √ (- 2 - 0) ² - (5 - ( - 3))  ²

= √ ( - 2) ² - (5 + 3) ²

= √ ( - 2) ² - (8) ²

the image (new coordinate) after the translation is (-2.5, 9.8)

Here we have a rule (also called a transformation or an operator) that works as:

T(x, y) = (x - 7.5, y + 6.8)

So we decrease the x-value by 7.5 and increase the y-value by 6.8. This is a translation of 7.5 units to the left and 6.8 units upwards.

Now, our point is (5, 3), if we apply that transformation we will get:
