Mathematics
1 answer:
Mrrafil [7]3 years ago
5 0

Answer:

56 hours

Step-by-step explanation:

we know that  

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

x -----> the number of hours

y ----> the amount earned in dollars

This problem represent a proportional relationship between the variable x and the variable y

Find the value of the constant of proportionality k

k=y/x

For (3,27) ----> k=27/3=9\ \$/h

For (9,81) ----> k=81/9=9\ \$/h

For (21,189) ----> k=189/21=9\ \$/h

The constant of proportionality k is 9

The linear equation is

y=9x

For y=$500

substitute in the equation and solve for x

500=9x

Divide by 9 both sides

x=56\ hours

Scale drawing of the electronics board
lora16 [44]

Area of the electronic board is 9000 cm2

Step-by-step explanation:

Write ratios to represent the unknown actual length and width of the display to the scale length and width of the display.

The Electronic board always seems like a rectangular shape

Length= scale÷Actual = 5/36 = 5×36 = 180cm

Length= scale÷Actual = 5/36 = 5×36 = 180cm

Width=scale÷Actual = 1/50 = 1×50 = 50cm

Width=scale÷Actual = 1/50 = 1×50 = 50cm

Area of Rectangle = legnth × width

                         = 180cm × 50cm = 9000 cm2

= 180cm  × 50cm = 9000 cm2

Area of the electronic board is 9000 cm2
