​ On a certain hot​ summer's day, 335 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $619.2. How many children and how many adults swam at the public pool that​ day?

Answers

Answer 1

Answer:

57

Step-by-step explanation:

Let c represent the number of children ($1.75 each) and a represent the number of adults ( $2.00 each).

We know that there were 340 people total, so c + a = 340. This implies that a = 340 - c

We also know that $1.75 c + $2.00 a = $609.25

By substituting a with 340 -c we have $1.75 c + $2.00 (340 -c) = $609.25

Use the distributive property to obtain $1.75 c + $680 - $2.00 c = $609.25

Subtract $680 from both sides and combine like terms to get - $0.25 c = -

$70.75

Now, divide both sides by -$0.25 to get c = 283, the number of children.

The number of adults is 340 - c or 340 - 283 = 57

3)f( 1)
4) g(5)
5) f(3)
6) g(-3)

Answers

Step-by-step explanation:

1 .f(x)=[tex]x^{2}[/tex]-x+1

   f(-1)= (-1)-(-1)+1

   f(-1)= 1+1+1

      = 3

3.f(x)=[tex]x^{2}[/tex]-x+1

 f( 1)=(1)-1+1

  f( 1)=1-1+1

        =1

5. f(x)=[tex]x^{2}[/tex]-x+1

Answer: 5.3571

Step-by-step explanation:

The formula used to calculate direct proportion is: y = kx

We will find the constant of proportionality when y=10 and x=5.6. This will be:

y = kx

10 = 5.6k

k = 10/5.6

k = 1.7857143

y = kx

y = 1.7857143 × 3

I have to find the missing angles​

Answers

Answer:

11 & 12 = 19⁰

13 = 71⁰

14, 15, 16 & 17 = 90⁰

18 & 20 = 78⁰

19 = 12⁰

Step-by-step explanation:

14,15,16 and 17 are formed from perpendicular lines. They are not counted as angles for the kite because, the are in the middle of the kite, not at the side...

You can easily find the angles using the triangle angles formula...to find 12,

180 - 90 - 71 = 19

To find 20 & 18, with the same method,

180 - 90 - 12 = 78
