The possibility of flipping heads is 1 in 2 (1/2)
the possibility of pulling a black card is 26 in 52 (26/52) which equals 1 in 2 (1/2)
multiply those together and you get 1 in 4, 1/4, or a 25%

Answer:

1/4

Step-by-step explanation:

The probability of flipping a coin and landing a heads is 1/2. Their are 26 black cards in a standard deck of 52 cards- 26/52 (1/2). Multiply the fractions to get the probability.

1/2 * 1/2 = 1/4

Write a linear equation in slope-intercept form: 5y – 3x + 20 = 0 ​
Arturiano [62]

Slope intercept form is y = mx+ b

So in order to turn 5y-3x + 20 = 0 into Slope intercept form, all we need to do is solve for y!

Let's do it!

  • add 3x to the right side of the equation

<u>5y - 3x + 20 = 0</u>

<u>5y + 20 = 3x </u>

  • move 20 to the right side

<u>5y = 3x - 20 </u>

  • Divide both sides of the equation by 5

y = 3/5x - 4

This is our answer!

A certain book is for sale in both Belize and Brazil. In Belize, it sells for 80.39 Belize dollars. In Brazil, it sells for 63.6
kompoz [17]
A book is sold in Belize for 80.39 Belize dollars.
In Brazil, it sells for 63.65 Brazilian reals.

The exchange rate of US Dollars to Belize Dollars is 1:1.9246
<span>The exchange rate of US Dollars to Brazilian Real is 1:1.7880
</span>
If we convert the two into dollars,
Belize Dollars 
1 : 1.9246 = X : <span>80.39 
1.9246X = 80.39
X = $ 41.77 

</span>Brazilian Real
1 : 1.7880 = X : 63.65 <span> 
</span>1.7880X = 63.65 <span>
X = $ 35.60
</span>
Difference = $ 41.77 - $ 35.60
Difference = $ 6.17

<span>So, in Belize the book is more expensive by $ 6.17</span>
