If you have a job that earns $120 in 2 days, how much would you earn in 6 days? Use a chart to show the proportion of earnings f

zepelin [54]

To figure this out, we need to use fractional proportions.

Currently, we have $120, the amount earned, and 2 days, the current rate.
Our fraction for this is: 120 / 2 = x / 6, x being the amount earned in 6 days.

Let's use a little technique to help us answer faster.

With our current money earned, 120, and our current days, 2, we can divide 120 by 2 to find out how many we earned in 1 day.

120 / 2 = 60.

We earned $60 per day.

With this formula, 60d, d being the amount of days, we can solve quicker.

We are solving for 6 days, so multiply $60 by 6 days.

60 x 6 = 360

Your proportion is :

120/2 : 360/6

I hope this helps!

Linear System, substitutional method 5x+4y=32 9x-y=33 helppp

Pachacha [2.7K]

5x + 4y = 32 ⇒ 45x + 36y = 288
9x - 1y = 33 ⇒ 45x - 5y = 165
 41y = 123
 41 41
 y = 3
 5x + 4(3) = 32
 5x + 12 = 32
 - 12 - 12
 5x = 20
 5 5
 x = 4
 (x, y) = (4, 3)

The tax rate is 3.9% What is the tax on 42$? Round to the nearest hundredth

mafiozo [28]

To find the total price, we use this equation:
42 + 0.039(42)
We can make it simpler:
1.039(42)
Multiply:
43.638
Because we're rounding
The total price is $43.64

Rina8888 [55]

Total cost of canvas required in making the tent is rupees 79128

Solution:

Given:

Height of the cylindrical tent = h = 3.3 m

Diameter of it's base = d = 100m

$radius = \frac{diameter}{2} = \frac{100}{2} = 50$
