C^2 = a^2 + b^2

1. c^2 = 4^2 + 5^2
c^2 = 16 + 25
c^2 = 41
c = √41
c = 6.40

2. 25^2 = 15^2 + b^2
625 = 225 + b^2
400 = b^2
b = √400
b = 20

3. 60^2 = a^2 + 48^2
3600 = a^2 + 2304
1296 = a^2
a = √1296
a = 36

Larry and Tyrik are planning cookout. Larry bought 10 steaks and 20 chickens and spent $90. Tyrik bought 30 steaks and 15 chicke

Harrizon [31]

10x+20y=90 and 30x+25y=180 represents the situation.

Step-by-step explanation:

Given,

Larry bought = 10 steaks and 20 chickens

Larry spent = $90

Tyrik bought = 30 steaks and 25 chickens

Tyrik spent = $180

Let,

x be the cost of one steak.

y be the cost of one chicken.

According to given statement;

10x+20y=90

30x+25y=180

10x+20y=90 and 30x+25y=180 represents the situation.

Paula bought a ski jacket on sale for $6 less than half it’s original price.She paid $88 for a jacket.What was the original pric

ohaa [14]

1/2x - 6 = 88....where x = the original price
1/2x = 88 + 6
1/2x = 94
x = 94 * 2/1
x = 188 <==

The probability that Paul wins a raffle is given by the expression n/n+6. Write down an expression, in the form of a combined si

Elza [17]

Answer:

$P(W') = \frac{6}{n+6}$

Step-by-step explanation:

<em>Let P(W) represents the probability that Paul wins</em>

<em>Let P(W') represents the probability that Paul does not win</em>

Given

$P(W) = \frac{n}{n+6}$

Required

$P(W')$

In probability, the sum of opposite probability equals 1;

This implies that

$P(W) + P(W') = 1$

Substitute $P(W) = \frac{n}{n+6}$ in the above equation

$P(W) + P(W') = 1$ becomes

$\frac{n}{n+6}+ P(W') = 1$

Subtract $\frac{n}{n+6}$ from both sides

$\frac{n}{n+6} - \frac{n}{n+6} + P(W') = 1 - \frac{n}{n+6}$

$P(W') = 1 - \frac{n}{n+6}$

Solve fraction (start by taking the LCM)

$P(W') = \frac{n + 6 - n}{n+6}$

$P(W') = \frac{n - n + 6}{n+6}$

$P(W') = \frac{6}{n+6}$

Hence, the probability that Paul doesn't win is $P(W') = \frac{6}{n+6}$
