Ardi and Lei are both travelling by train. Ardi's train travels 70 km in 35 minutes. Lei's train travels 585 km. It leaves at 9:

Leni [432]

Answer:

10 km/hr

Step-by-step explanation:

Average speed = Total distance travelled / Total time taken

Ardi:

Total distance travelled = 70 km

Total time taken = 35 minutes = 35/60 hour

Average speed = Total distance travelled / Total time taken

= 70 km ÷ 35/60 hr

= 70 × 60/35

= 4,200/35

= 120 km/hr

Lei:

Total distance travelled = 585 km Total time taken = 9:05 - 13:35 = 4 hours 30 minutes

= 4.5 hours

Average speed = Total distance travelled / Total time taken

= 585 km / 4.5 hours

= 130 km/hr

Difference, in km/h, between the average speed of their trains = Lei's train - Ardi's train

= 130 km/hr - 120 km/hr

= 10 km/hr

Multiply and simplify.

miv72 [106K]

Multiply and simplify (3 + i)(4 + 2i)

(3 + i)(4 + 2i) = (3*4) + (3*2i) + (4*i) + (2i*i) = 12 + 6i + 4i + 2i^2

i^2 = -1

12 + 6i + 4i + 2i^2 = 12 + 6i + 4i -2 = 10 + 10i

Use the imaginary number i to rewrite the expression:

- $-\sqrt{-16} \\(-1)\sqrt{(-1)16}\\(-1)\sqrt{16}i\\(-1)4i\\-4i$

Company A makes three different group of products, There are liquid products, solid products, and gas products. The ratio of liq

wel

Answer: Total products = 108

Step-by-step explanation: Ratio of solid to liquid products is 3:4 and there are 36 solids, so:

$\frac{3}{4} = \frac{Pl}{36}$

$Pl = \frac{36.3}{4}$

Pl = 27

Ratio of solid to gas is 4:5:

$\frac{4}{5}=\frac{36}{Pg}$

$Pg=\frac{36.5}{4}$

Pg = 45

Total products is the sum of all products:

P = Ps + Pl + Pg

P = 36 + 27 + 45

P = 108

There are a total of 108 products.

Fridays high tempature was -1c the low tempature was -5c what was the difference between the high and low temperatures

Elis [28]

Since both temperatures were below zero ( both are negative numbers) all you need to do is subtract them:

5 - 1 = 4

The difference was 4 degrees.
