There are 8 coins total, so that is your denominator.
There are 3 dimes and 2 quarters, so add them together and you get 5 which is your numerator.
5/8 should be the fraction you end up with :)
Answer:
Step-by-step explanation:
arc ST is 122° , it's the same as that inner angle
arc RT ( not asked for, but needed ) is 180 °
then arc RS is 360 -180-122= RS
58= RS
Then SRT is a racing version of cars from Chrysler / Dodge :0 or also for this problem it's 180+58 =238°

Answer:
<em>72 passenger planes</em>
Step-by-step explanation:
ratio passenger to cargo = 8 to 5 = 8/5
Let p = number of passenger planes.
The ratio of passenger to cargo planes that actually landed is p/45.
The ratio in general is 8/5, so 8/5 must equal p/45.
p/45 = 8/5
5p = 45 * 8
p = 9 * 8
p = 72
12 x 4.89 = 50.68
17 x 4.72 = 80.24
15 x 5.09 = 76.35
50.68 + 80.24 + 76.35 = $207.27
The driver has to drive 20 miles to come back to the starting point directly
Step-by-step explanation:
The driver has driven in the form of two legs on a right-angled triangle where the vertical side (perpendicular) is 12 miles and the horizontal side (base) is 16 miles.
Now as the driver has to return back to the starting point directly, it will form a right-angled triangle making the direct path a hypotenuse
So,
B = 16
P = 12
H = ?
we have to find the hypotenuse
As the triangle is a right angled triangle, we can use the Pythagoras theorem to find the length of hypotenuse So,
taking Square root on both sides
So
The driver has to drive 20 miles to come back to the starting point directly
