This Is A Scale Drawing OfA Ski Chalet. The Height Ofthe Chalet In The Drawingis 7 Inches. The Scale

Answers

Answer 1

Answer:

Actual height of the Chalet = 45.5 ft

Step-by-step explanation:

Given:

Height of chalet in drawing = 7 inches

Scale of drawing = 1 inch : 6.5 ft

Required:

Actual height of the Chalet

SOLUTION:

Actual of height of the Chalet can be calculated using proportion as follows,

Let the actual height be x.

Thus,

1 in : 6.5 ft = 7 in : x ft

[tex] \frac{1}{6.5} = \frac{7}{x} [/tex]

Cross multiply

[tex] 1*x = 7*6.5 [/tex]

[tex] x = 45.5 ft [/tex]

Actual height of the Chalet = 45.5 ft

Here is a system of equations:
-7x + 3y = -65
-7x + 10y = -135
Write an equation that results from subtracting the two equations.

Answers

Answer:

y = -10

Step-by-step explanation:

(-7x+3y) - (-7x +10y) =-65 -(-135)

-7x + 3y + 7x -10y = 70

-7y = 70

y = -10

The equation that results from subtracting - 7x + 3y = - 65 and

- 7x + 10y = - 135 is 7y = - 70.

What are simultaneous equations?

We know two simultaneous equations have a unique solution when they intersect at a point,

when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.

Given, a system of equations - 7x + 3y = - 65 and - 7x + 10y = - 135.

Subtracting the first equation from the second we get,

   - 7x + 10y = - 135

(-) - 7x + 3y =    - 65

_________________

Negative sign gets distributed

   - 7x + 10y = - 135

  + 7x - 3y =   + 65

_________________

            7y =   - 70

              y =   - 70/7

              y =  - 10.

So, the value of x is -7x +10×(-10) = - 135.

- 7x - 100 = - 135.

- 7x = - 135 + 100.

- 7x = - 35.

x = 7.

m(n+r)=s solve for n. Show two methods.

Answers

9514 1404 393

Answer:

n = (s/m) -r n = (s -mr)/m

Step-by-step explanation:

1. Undo the operations done to n, in reverse order. Here, n has r added and the sum is multiplied by m. First we divide by m, then we subtract r.

  m(n+r) = s . . . given

  n +r = s/m . . . divide by m

  n = (s/m) -r . . . subtract r

__

2. Eliminate the parentheses, then proceed as above. Subtract the added term, then divide by the coefficient of n.

  m(n+r) = s

  mn +mr = s . . . eliminate parentheses

  mn = s -mr . . . subtract the added term

  n = (s -mr)/m . . . divide by the coefficient of n

A salesperson works 40 hours per week at a job where she has two options for being paid. Option A is an hourly wage of $26. Option B is a commission rate of 10% on weekly sales. How much does she need to sell this week to earn the same amount with the two options?​

Answers

Step-by-step explanation:

12,500.

Step-by-step explanation:

We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of $25. Option B is a commission rate of 8% on weekly sales.

First of all we will find amount earned by salesperson with option A.

\text{Option A earnings}=40\times 25=1000Option A earnings=40×25=1000

The salespersons earns $1000 through option A.

Let x be the amount of weekly sales.

8% of x should be equal to 1000 for salesman to earn the same amount with the two options.

\frac{8}{100}x=1000

100

8

x=1000

0.08 x=10000.08x=1000

x=\frac{1000}{0.08}x=

0.08

1000

x=12500x=12500

Therefore, the salesman needs to make a weekly sales of $12,500 to earn the same amount with two options.

Answer: 9,500.

y=-3 cos(2x) is the equation has a maximum at (4π , 3) and a minimum at (4π , -3)

What is Trigonometry?

The study of correlations between triangles' side lengths and angles is known as trigonometry.

The sine function's parameters, a, b, c, and d, must be adjusted using the sliders.

Now, Finding the equation with a maximum at (4π , 3) and a minimum at (4π , -3) is necessary.

Thus, Setting the values for the slider requires setting a to -3, b to 2, and c to 0.

Hence, The solution, y=-3 cos (2x), should match the equation obtained from the sliders.

What is an Equation?

An equation is a mathematical statement containing two expressions on either sides which are connected with an equal to sign.

Either sides of an equation is called as left hand side and right hand side.

Given equation is,

-9x + 1 = -x + 17

We have to find the solution of the given equation.

Take the like terms together.

Subtracting one on both sides,

-9x = -x + 16

Adding x on both sides,

-8x = 16

Dividing by -8 on both sides,

x = -2

Hence the solution is x = -2.
