Answer:

Adult tickets = $73.5

Child tickets = $20.5

Step-by-step explanation:

{ \rm{3x + 5y = 50 -  -  -  \{eqn \: 1 \}}} \\ { \rm{x + 5y = 31 -  -  -  \{eqn \: 2 \}}} \\

• Subtract eqn 2 from eqn 1:

{ \rm{2x = 21}} \\ { \rm{x = 10.5}}

{ \rm{10.5 + 5y = 31}} \\ { \rm{5y = 20.5}} \\ { \rm{y = 4.1}}

Precipitation for the month of March was 6 ½ inches less than average. In April, the precipitation was 2 ⅜ inches less than aver
deff fn [24]

Answer:

The precipitation for both March and April was 8 7/8 inches below average

Step-by step explanation;

For the month of march, precipitation was 6 1/2 inches less than average

For the month of April, precipitation was 2 3/8 inches left.

Now we want to calculate how many inches less than average was precipitation in both wants

What we simply do here is to add the inches with which they were both left than average in both months

That would be;

6 1/2 + 2 3/8

= 13/2 + 19/8 = (52 + 19)/8 = 71/8 = 8 7/8 inches

Plzz help <br><br>find value of following : 2sin75°.cos15°​
polet [3.4K]

Answer:

\frac{2+\sqrt{3} }{2}

Step-by-step explanation:

Using the product to sum formula

sinxcosy = \frac{1}{2} [ sin(x + y) + sin(x - y) ] , then

2sinxcosy = sin(x + y) + sin(x - y)

Given

2sin75°cos15° ← with x = 75 and y = 15 , then

= sin(75 + 15) + sin(75 - 15)

= sin90° + sin60°

= 1 + \frac{\sqrt{3} }{2}

= \frac{2+\sqrt{3} }{2}
