the sum of two numbers is 83. The difference of the 2 numbers is 13. What is the product of the two numbers?

Answers

83-13=70 divide by 2 =35+13=48= 35x48=1680

The product of the two numbers whose sum and difference is 83 and 13 respectively is 1680.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is that the sum of two numbers is 83 and the difference of these two numbers is 13.

Assume that the numbers are [x] and [y] respectively. Then -

x + y = 83 ...[1]

and

x - y = 13

x = 13 + y

Substitute (x = 13 + y) in Equation [1], we get -

13 + y + y = 83

2y = 70

y = 35

Therefore, [x] will be equivalent to -

x = 13 + 35

x = 48

Now, the product of [x] and [y] will be -

xy = 35 x 48 = 1680

Therefore, the product of the two numbers whose sum and difference is 83 and 13 respectively is 1680.

Web flixs charges $25 and $2 for each movie family video charges $10 plus $2.50 for each movie find the number of movie rental for both stores charge are the same

Answers

The number of movie rentals would be 30
To find the answer you have to do this
(M stands for movies)
$25 + 2m = $10 + 2.50m
-10 -2m -10 -2
$15 = .50m
Divide .50/15
You get 30
Check your answer $25 + 2(30) = $10 + 2.50(30)
$25 + $60 = $10 + $75
$85 = $85

Final answer:

The number of movie rentals for which Web Flixs and Family Video charge the same is 30.

Explanation:

To find the number of movie rentals for which Web Flixs and Family Video charge the same, we need to set up an equation and solve for the number of movies. Let's denote the number of movie rentals as 'x'.

For Web Flixs, the cost is $25 + $2 per movie, so the total cost can be expressed as 25 + 2x.

For Family Video, the cost is $10 + $2.50 per movie, so the total cost can be expressed as 10 + 2.50x.

To find the number of movie rentals for which the costs are the same, we set up the equation: 25 + 2x = 10 + 2.50x.

By rearranging the equation and solving for 'x', we can find the number of movie rentals:

25 - 10 = 2.50x - 2x

15 = 0.50x

x = 30

Therefore, when the number of movie rentals is 30, the charges at both Web Flixs and Family Video will be the same.

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900. For each salesman, write an equation showing the relationship between their weekly paycheck amount, p, and the number of sales, s, they had that week. Graph the three equations you just wrote for each salesman if they have between 0 and 20 sales in a week. Graph all three equations on the same graph . Make sure you label each line with the salesman it represents, as well as label the axes. Note: The independent variable is s, and the dependent variable is p.

Answers

GIVEN:
Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.
Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn.
Salesman C does not earn any commission. His weekly salary is $900.

Salesman A: 1300 ≤ 65S
Salesman B: P = 40S + 300
Salesman C: P = 900

Salesman A can only have 20 sales. 1,300/65 = 20. It should not go beyond that because it will go beyond the limit of 1,300 per week.

Salesman B will earn 1,100 for 20 sales. P = 40(20) + 300 = 800 + 300 = 1,100.

Salesman C will earn 900 regardless if he had 0 or 20 sales for the week.

Solution-

420/10= 42

42 words per min

42*180= 7560

Answer-
At this rate Sam will be able to type 7,560 words in 3 hours.

Final answer:

Sam can type 7,560 words in 3 hours if he continues typing at the same speed that is 420 words in 10 minutes.

Explanation:

The problem is asking to find out how many words Sam can type in 3 hours if he continues at the rate of typing 420 words in 10 minutes. First, we need to convert 3 hours to minutes since the typing speed is given in terms of minutes. There are 60 minutes in an hour, so 3 hours equals 180 minutes. Typing speed is calculated by dividing the total number of words by the total time. In this case, Sam's typing speed is 420 words / 10 minutes = 42 words per minute. Considering his typing speed, in 180 minutes (3 hours), he should be able to type 42 words per minute * 180 minutes = 7560 words. Therefore, the correct answer is D.7,560.

please help. ive been on this problem for almost an hour now

Answers

Answer: [tex]y = \frac{1}{3}x+\frac{1}{3}[/tex]
Note: the slope is 1/3 and the y intercept is 1/3

------------------------------------------------------

Explanation:

First we need the slope of the line through the two points. Use the slope formula

m = (y2 - y1)/(x2 - x1)
m = (2-1)/(5-2)
m = 1/3

The slope is m = 1/3

Use this slope, along with one of the points. I'll use the point (x,y) = (2,1). Plug these three values into the equation y = mx+b and then solve for b

y = mx+b
1 = (1/3)(2)+b
1 = 2/3+b
1-2/3 = 2/3+b-2/3
1 - 2/3 = b
b = 1 - 2/3
b = 3/3 - 2/3
b = 1/3

So the slope and y intercept are
m = 1/3
b = 1/3

Therefore the equation is [tex]y = \frac{1}{3}x+\frac{1}{3}[/tex]

The velocity of an airplane heading east is 400 knots with a wind velocity of 50 knots blowing toward the northeast. Calculate the resultant speed and direction of the plane. Round to the nearest tenth.

Answers

1. To Calculate the resultant speed of the plane, you need to find the speed of the air, add it to the plane speed, then find the resultant using trigonometry.

The velocity of the plane:
east=400 knots

The velocity of the air
50knots north east = 50/√2 north + 50/√2 east

The resultant speed would be:
total speed^2= east^2 + north^2
total speed= √(400+50/√2)^2 + (50/√2)^2
total speed= √(189534.254 + 1250)
total speed= 436.8 knots

2. To count the direction of the plane, you need to find the total speed of x(east/west) and y(north/south) axis separately then use tan formula.
east speed= 400knots + 50/√2 knots= 435.35 knots
north speed= 50/√2knots= 35.35 knots

tan a= opposite/adjacent
tan a = north speed/ east speed
tan a= 35.35/ 435.35
tan a=0.0812
a= 4.6 degrees

The amount of money it takes to fill up your gas tank varies directly with the number of gallons you buy. You spent $16.56 to fill up your car with gasoline. If you bought 6 gallons of gasoline, what is the constant of variation

Answers

The constant of variation is 2.76 dollars per gallon

Let "m" represent the money required.

Let "n" represent the number of gallons filled.

Since it is given to us that the amount of money it takes to fill up your gas tank varies directly with the number of gallons you buy, therefore, this can be written mathematically as:

[tex] m\propto n [/tex]

We know that when we remove the "varies to" sign we have to replace it with the equal to sign and the constant of variation, which we will represent by the letter "k".

Therefore the above expression will become:

[tex] m=k\times n [/tex]

Now, it is given that m=$16.56 and n=6 gallons

Therefore, [tex] 16.56=k\times 6 [/tex]

Dividing both sides by 16.56 we get:

[tex] \therefore k=\frac{16.56}{6}=2.76 [/tex]

Thus, k=2.76 $/gallon is the value of the constant of variation.

triangle LMN is similar to triangle XYZ with altitudes KL and WX. Find KL

Answers

KL is 7.

Since LMN~XYZ, that means m∠N = m∠Z.

Since the angles are the same, we also know that
sin N = sin Z

Sine is the ratio of the opposite side to the hypotenuse of a right triangle. The sine of N would be the ratio of sides LK to LN, and the sine of Z would be the ratio of sides XW to XZ. That gives us:

x/28 = 3/12

Cross multiply the proportion:

12*x = 28*3
12x = 84

Divide both sides by 12:
12x/12 = 84/12
x = 7

The side length (KL) of the triangle ΔLMN will be 7. Then the correct option is B.

What is the triangle?

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

The triangle ΔLMN is similar to triangle ΔXYZ with altitudes KL and WX.

The ratio of the corresponding sides will remain constant. Then the equation is given as,

KL / XW = LN / XZ

KL / 3 = 28 / 12

KL = (28 x 3) / 12

KL = 84 / 12

KL = 7

The side length (KL) of the triangle ΔLMN will be 7. Then the correct option is B.
