Answer:

210 km

Step-by-step explanation:

90 * 2 is 180 (distance over 2 hours)

20 minutes is .333 hours, so 90*0.333 is about 30 km

and 180+30 is 210.

Answer:

210km

Step-by-step explanation:

2 hours=90km×2hr=180

20mins converted to a fraction is 0.333hr

180+30

=210

1) c) y = 500 * 2^x 
In year 1, x = 1 and the population is 500 * 2^1 = 1000
In year 2, this doubles to 500 * 2^2 = 500 * 4 = 2000
ans so on
This model describes the population doubling every year

2) 
A) 3 (1/2)^x and C) (0.25)^x
These numbers reduce as x increases because there is a number with an absolute value less than 1 is being raised to the power of x. They also will never totally reach zero or become negative, but will approach zero as x becomes very large.

A 50. kg remote control car is accelerating on a flat road, and the free body diagram for the car is shown below. If the force o
goldfiish [28.3K]

Answer:

12 m/s²

Step-by-step explanation:

mass of the car = 50 kg

The net force applied to the car is 800 - 200 = 600 N

Form the Newton's second law:

F = m*a

where F is the net force applied to the object, m is the mass of the object, and a is the acceleration of the object.

Then, the acceleration of the car (in m/s²) is:

a = F/m

a = 600/50

a = 12 m/s²

In autumn a tree starts to shed its leaves. 2/5 of the leaves fall off in the first week. 1/2 of those remaining fall of in the
Oduvanchick [21]

Answer:

850 leaves were on the tree initially.

Same as;

2/5 + 1/5 + 3/10 + (remaining leaves 1/10) = 1

4/10 + 2/10 + 3/10 + 1/10

10 x 85 = 850

Step-by-step explanation:

2/5  wk 1 fall off

1/5  wk 2 fell off

3/5 x 1/2  = 3/10 wk 2 stayed on tree

1/3 x 3/10 = 1/10 wk 3 stayed on

2/5 + 1/5 + 3/10 = 9/10 =  0.9 fall off in total

10/10 - 9/10 = 1/10 left on tree

1/10 = 85

10 x 85 = 850 leaves.
