The answer is A.

to solve this use the equation lp/2+B.

first replace the l with 3.5, the slant height. then find the perimeter of the base (p) by multiplying 4.5 by 3.

Divide all of that by 2 then add 8.78 (The area of the base [calculated by dividing 4.5 by 2 then multiplying that by 3.9])

On a certain hot summer's day, 643 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for

lilavasa [31]

249 children and 394 adults swam at the public pool.

Step-by-step explanation:

Number of people swam at pool = 643

Receipts = $1161.50

Cost for one child = $1.50

Cost for one adult = $2.00

Let,

x be the number of children

y be the number of adults

According to given statement;

x+y=643 Eqn 1

1.50x+2.00y = 1161.50 Eqn 2

Multiplying Eqn 1 by 2

$2(x+y=643)\\2x+2y=1286\ \ \ Eqn\ 3\\$

Subtracting Eqn 2 from Eqn 3

$(2x+2y)-(1.50x+2.00y)=1286-1161.50\\2x+2y-1.50x-2.00y=124.50\\0.5x=124.50$

Dividing both sides by 0.5

$\frac{0.5x}{0.5}=\frac{124.50}{0.5}\\x=249$

Putting x=249 in Eqn 1

$249+y=643\\y=643-249\\y=394$

249 children and 394 adults swam at the public pool.

KatRina [158]

Answer: r=7x-1/8

Step-by-step explanation:

2(4r+3)=7x/2+5/2

4r+3=7x+5/2

4r+3-3=7x+5/2 -3

4r=7x+5/2 -3

4r/4= 7x-5/2/4 -3/4

r=7x-1/8
