On one day, 4 chefs and 5 helpers earned $650.

On another day working the same number of hours
at the same rate of pay, 5 chefs and 6 helpers
earned $800.

How much does a chef earn each
day?

Answers

Answer 1
4c + 5h = 650 and

5c + 6h = 800 where c are chefs, h are helpers

Start by finding an expression for c

4c + 5h = 650
4c = 650 -5h
c = (650- 5h)/4

Then substitute that into the second equation and solve for a number value for h
5 (650-5h)/4 + 6h = 800
(3250-25h)/4 + 6h = 800
Multiply both sides by 4
3250-25h + 24h = 3200
-h = -50
h = 50

Take that 50 and substitute it into the expression we have for c to get a number value for c

C= 650-5(50)/4
C = 650-250/4
C = 400/4
C= 100

Check your first equations, substituting $50 for the helpers and $100 for the chefs.

4 (100) + 5(50) =
400 + 250 = 650

5(100) + 6(50) =
500 + 300 = 800

Find the H.C.E of 108 and 72.​

Answers

Answer:

36 is the HCF of 108 and 72

Answer:

36.

Step-by-step explanation:

HCF of 108 and 72

108 = 2 * 2 * 3 * 3 * 3

72 = 2 * 2 * 2 * 3 * 3

So picking out the common factors we have

HCF = 2 * 2 & 3 * 3

= 4 * 9

= 36.

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the zeros 0,1, and 1+i

Answers

Answer:

[tex]f(x)=x(x-1)(x^2-2x+2)[/tex]

Step-by-step explanation:

The standard polynomial is given by:

[tex]f(x)=a(x-p)(x-q)...[/tex]

Where a is the leading coefficient and p and q are the zeros.

We are given that the zeros are x = 0, 1, and 1 + i.

First, by the Complex Root Theorem, if 1 + i is a zero, then 1 - i must also be a zero.

Therefore:

[tex]f(x)=1(x-(0))(x-(1))(x-(1+i))(x-(1-i))[/tex]

Simplify:

[tex]f(x)=x(x-1)(x-(1+i))(x-(1-i))[/tex]

Expand the third and fourth factors:

[tex](x-(1+i))(x-(1-i))=(x-(1+i))(x)-(x-(1+i))(1-i)[/tex]

Distribute:

[tex]=x^2-x-ix-(x(1-i)-(1+i)(1-i))[/tex]

Expand:

[tex]=x^2-x-ix-x+ix+(1-i+i-i^2)[/tex]

Therefore:

[tex]=x^2-2x+(2)=x^2-2x+2[/tex]

Hence, our polynomial function is:

[tex]f(x)=x(x-1)(x^2-2x+2)[/tex]

a rectangle has a length of 8m and a width of 4.5m. A parallelogram has a length of 6 m. The area of the parallelogram is twice the area of the rectangle. What is the height of the parallelogram

Answers

Answer:

12m

Step-by-step explanation:

work out the area of the rectangle then times it by 2 because the parallelogram is twice the area of the rectangle. 8 × 4.5m = 36m². 36 ×2 = 72cm². Now you do 72 ÷ 6 = 12 . the answer is 12m.

The height of the parallelogram is 12 meters.

What is a rectangle?

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

The area of a rectangle is given by the formula A = lw, where l is the length and w is the width.

The area of the rectangle is A1 = lw = (8 m)(4.5 m) = 36 m².

The area of a parallelogram is given by the formula A = bh, where b is the base and h is the height.

Since the area of the parallelogram is twice the area of the rectangle, we have:

2A1 = A2

2(36 m²) = 72 m²

So the area of the parallelogram is A2 = 72 m².

We are given that the length of the parallelogram is 6 m, so we can use the formula for the area to solve for the height:

A2 = bh

72 m² = (6 m)h

h = 12 m

Therefore,

The height of the parallelogram is 12 meters.

Which is the inverse of the function f (x) = 1/4x + 1/2

Answers

Answer:

f⁻¹(x) = 4x - 2

Step-by-step explanation:

To find the inverse of a function, switch the places of x and y (or f(x)).

f(x) = 1/4x + 1/2 → y = 1/4x + 1/2

Switch the variables.

x = 1/4y + 1/2

Now you want to convert the equation back into y = mx + b form.

x = 1/4y + 1/2

Subtract 1/2 from both sides.

x - 1/2 = 1/4y

Now, you want to isolate y further by dividing both sides by 1/4 (or multiplying by 4).

4(x - 1/2) = y

Distribute the 4.

4x - 2 = y → y = 4x - 2 → f⁻¹(x) = 4x - 2

This is the inverse of your given function.

Answer:

The equation of the Parallel line to the given line is  5x+y-7=0

Step-by-step explanation:

Explanation:-

Given that the line y = - 5x+4 and point (1,2)

The equation of the Parallel line to the given line is  ax+by+k=0

Given straight line  5x + y -4 =0

The equation of the Parallel line to the given line is  5x+y+k=0

This line passes through the point (1,2)

             5x+y+k=0

            5(1)+2+k=0
