Answer:

36 cm^2.

Step-by-step explanation:

The area is half the product of the lengths of its diagonals.

(PA)(LY) = (12cm)(6cm)

= 72 cm

72cm ÷2= 36 cm^2

Therefore the area is 36 cm^2

A total of 750 tickets were sold for the school play. They were either adult tickets or student tickets. There were 50 more stud

Vlada [557]

Answer:

350 adult tickets were sold.

Step-by-step explanation:

Let's set up some values:

x = adult tickets

x + 50 = student tickets, since there were 50 more student tickets than adult tickets.

Now, let's set up our equation. If these two values add up to 750 tickets, then we can conclude the following:

(x) + (x + 50) = 750

2x + 50 = 750

2x = 700

x = 350 adult tickets. This means there were 400 student tickets sold.

On a trip, Duke encounters some road construction that slows him down. While he is able to go 60 mph on the highway and 40 mph t

natulia [17]

Answer:

Time taken by Duke on the highway = 3 hours

Time spent on the construction = 6 hours

Time spent in the city = 2 hours

Step-by-step explanation:

Speed by which Duke travels a distance on highway $d_1$ = 60 mph

Let the time taken to travel on highway = $t_1$ hours

Distance traveled = $60t_1$ miles

Speed in the city = 40 mph

Let the time taken = $t_2$ hours

Distance traveled in the city = $40t_2$ miles

Speed on the construction = 20 mph

Let the time spend on the construction = $t_3$ hours

Distance traveled on the construction = $20t_3$ miles

Since, total distance covered = 380 miles

$d_1+d_2+d_3=60t_1+40t_2+20t_3$

He spends one half the time on the highway as he does on the construction,

$t_3=2t_1$

Total time spent in the trip = 11 hours

Therefore, $t_1+t_2+t_3=11$

$t_1+t_2+2t_1=11$

$t_2=11-3t_1$

From equation (1),

$60t_1+40(11-3t_1)+20(2t_1)=380$

$60t_1-120t_1+40t_1+440=380$

$440-20t_1=380$

$20t_1=440-380$

$t_1=\frac{60}{20}$

$t_1=3$ hours

$t_2=11-3t_1=2$ hours

$t_3=2t_1=6$ hours

Therefore, time taken by Duke on the highway = 3 hours

Time spent on the construction = 6 hours

Time spent in the city = 2 hours
