Pretty sure you have to use the Pythagorean Theorem.
a^2+b^2=c^2

So you would plug in your numbers that you already have (6 and 10) But notice that 10 is the hypotenuse (longest side) so
6^2+x=10^2

Then you would solve it and you should end up with 11.6619

on a certain hot Summer's Day 613 people use the public swimming pool the daily prices are $1.75 for children $2.25 for adults t

Elodia [21]

389 children and 224 adults were at the pool that day.

Step-by-step explanation:

Cost of one child ticket = $1.75

Cost of one adult ticket = $2.25

Total people = 613

Total receipts worth = $1184.75

Let,

Number of children = x

Number of adults = y

According to given statement;

x+y=613 Eqn 1

1.75x+2.25y=1184.75 Eqn 2

Multiplying Eqn 1 by 1.75

$1.75(x+y=613)\\1.75x+1.75y=1072.75\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(1.75x+2.25y)-(1.75x+1.75y)=1184.75-1072.75\\1.75x+2.25y-1.75x-1.75y=112.00\\0.50y=112.00$

Dividing both sides by 0.50

$\frac{0.50y}{0.50}=\frac{112.00}{0.50}\\y=224$

Putting y=224 in Eqn 1

$x+224=613\\x=613-224\\x=389\\$

389 children and 224 adults were at the pool that day.

70 coins of 10 paise and 50 paise are kept in a purse. if the total value of the money in the purse is Rs 19 . find the no. of e

Allushta [10]

Answer:

10=40

50=30

Step-by-step explanation:

Suppose the number of 10 paise coins =x

∴ the number of 50 paise coins =70−x

Now, value of 10 paise coins = Rs.

10 x and value of 50 paise coins = Rs. 2 70−x

Total value of coins = 10 x + 2 70−x

∴ 10 x + 2 70−x =19

Multiplying both sides by 10, (LCM of 10,2=10), we get

x+5(70−x)=19×10

x+350−5x=190

−4x=−160

−4 −4x = −4 −160

∴x=40

∴ number of 10 paise coins =40

Number of 50 paise coins =70−40=30.
