Answer:

OC = 10.07 CM

BC = 9.73 cm

area triangle OAB = 97.98 cm^2

area of sector OADB = 150.05 cm^2

% of diagram that is shaded = 65%

Step-by-step explanation:

cos 44 = OC/14

0.71934(14) = OC = 10.07

sin 44 = BC/14

0.6947(14) = BC = 9.73

area of sector OADB = (88/380)(Pi)14^2) =150.05

area triangle OAB = (OC)(BC)(0.5)(2) = 97.98

% of diagram shaded = 97.98/150.05 = 0.65 = 65%

Eurostar is a high-speed railway service connecting
erma4kov [3.2K]

Answer:

Step-by-step explanation:

This is simply a units conversion problem.  It gives us for the number of passengers, the number of seats per carriage and the number of carriages per train.  To change the units from passengers to trains without changing the value, we use the multiplicative identity (that is, 1).

350000 passengers

(350000 passengers) * 1

(350000 passengers) * ((1 carriage)/(32 passengers)) * ((1 train)/(15 carriages)

   [note:  passengers and carriages cancel. Leaving only trains]

(350000)*(1/32)*(1/15) trains       [note: I write this way to paste into MS Excel]

729.1667  trains                 [oh, but don’t just round this number either up or down]

   729 full trains can carry 729*32*15 = 349920 passengers

   730 full trains can carry 730*32*15 = 350400 passengers

Now, we can say that 730 trains are adequate to carry 350000 passengers.

The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for
swat32
Let the price of flowers in September be x, then (100 + 20)/100 * x = $1.50
120/100 * x = $1.50
1.2x = $1.50
x = $1.50/1.2 = $1.25
The price of flowers in September is $1.25

Total money realised in September = $1.25 x 900 = $1,125
40% earned = 0.4 x $1,125 = $450

Total money realised in October = $1.50 x 700 = $1,050
40% earned = 0.4 x $1,050 = $420

The class earned more money in September and they earned $30 more than in October.
