Answer:

To convert m/sec to km/h the factor is 3.6

The speed of the airplane is 216\frac{km}{h}

Step-by-step explanation:

we know that

1\ km=1,000\ m\\1\ h=3,600\ sec

so

60\frac{m}{sec}=60\frac{(1/1,000)}{(1/3,600)}=60\frac{3,600}{1,000}=216\frac{km}{h}

To convert m/sec to km/h the factor is 3.6

That means ----> Multiply the speed in m/sec by 3.6 to obtain the speed in km/h

Mr. Dewalt suggested contacting a travel agent to see whether they could get a lower price. The agent found a price that was 30%
Dennis_Churaev [7]
First you have to know, that the price the agent found is 70% of  $2075
 (100%-30%=70%)
70%=0,7
$2075 * 0,7 = $1452,5
So 70% 0f $2075 is 1452,5

The price the agant found is $1452,5.

The value of an antique chair is expected to increase by 3% every year. If the chair was bought for $1,020 in 2001, find its exp
castortr0y [4]
Hi there
The formula is
A=p (1+r)^t
A future value?
P present value 1020
R rate of increases 0.03
T time 2,015−2,001=14 years
So
A=1,020×(1+0.03)^(14)
A=1,542.8 round your answer to get
A=1543

Hope it helps

Need help with the domain and range
Dmitry_Shevchenko [17]

Domain is basically all of x values.

Range is basically all of y values.

That means if you want to find the domain, you can check from the coordinate-x and if you want to find the range, you can check from the coordinate-y.  

As you can see in the graph, there are the colored and non-colored dot. Both present the inequality symbol. If it's a colored circle/dot then it's either ≤ or ≥ but if it is non-colored dot then it's either > or <

From the graph, we can say that the minimum value is at -4 when x = -5

and there is no maximum value considering the x = 1 then y = 7 isn't counted due to being uncolored dot.

As mentioned, Domain is the set of all x values. We check the coordinate-x plane and notice that it begins from x = -5 to x = 1. That means it is -5≤x<1

Remember that the x = 1 one is uncolored so it's either > or < but it is < because 1 has more value than -5. Now we know the domain.

About range, we check coordinate-y plane. It starts from -4 to 7. Therefore, the range is -4≤y<7.

Therefore, <em>Domain is -5≤x<1 and Range is -4≤y<7</em>
