A cart travels 3.6 meters in 1.8 seconds. What is the average speed of the cart?

1 answer:

6 0

For solving this we need the change in distance and the change in time. You said that the change in time is 1.8 seconds and the change in distance is 3.6 meters. ( This is assuming it started at 0 meters and started at 0 seconds )

Since the starting was 0,0 we can toss them out as they add no value. Now since speed is labeled (in this case) m/s, we divide how many meters it traveled over how many seconds it took to travel it.

3.6 / 1.8 = 2

The average speed of the cart is 2 m/s

A cell phone company has three different production sites.

dlinn [17]

Answer:

3/11

Step-by-step explanation:

given that a cell phone company has three different production sites

Site name 1 2 3 Total

Production 60% 30% 10% 100%

Recalled 5% 7% 9%

Prob for recall 0.003 0.021 0.009 0.033

Total probability for recall = 0.033

Prob for recall and came from site 3 = 0.009

So required probability

= If a randomly selected cell phone has been recalled, what is the probability that it came from Site 3

= $\frac{0.009}{0.033} \\=\frac{3}{11}$

Answer:

the answer is triangles ABC and DEC are similar

Step-by-step explanation:

angle C is a common angle for both triangles

angle D is equal to angle A ( corresponding angles)since they are parallel

angle B is also equal to angle B for the same reason as angle D and A

since the three angles of the two angles are equal they are similar

An aquarium tank can hold 7200 liters of water. there are two pipes that can be used to fill the tank. the first pipe alone can

Arada [10]

The first pipe pumps out

$\dfrac{7200\text{ L}}{48\text{ min}}=\dfrac{150\text{ L}}{1\text{ min}}$

while the second pipe pumps out

$\dfrac{7200\text{ L}}{96\text{ min}}=\dfrac{75\text{ L}}{1\text{ min}}$

So together, both pipes pump out

$\dfrac{150+75\text{ L}}{1\text{ min}}=\dfrac{225\text{ L}}{1\text{ min}}=\dfrac{7200\text{ L}}{32\text{ min}}$

That is, with both pipes filling the tank, it should take 32 minutes total.
