Answer:
Step-by-step explanation:
Original Ratio = New Ratio All these problems are done the same way. Try to conquer the language.
The original ratio = 24 inches wide / 12 inches tall
Shawna's new ratio = you don't know / 2 inches in height (or tall)
Call what you don't know = x
24/12 = x / 2 Cross multiply
12 * x = 24 * 2 Combine the right
12 * x = 48 Divide by 12
12x/12 = 48/12
x = 4
So the new height is 4 inches.
Find the discount price and subtract from the total to find the sale price.
To find the discount price, multiply 90 b 40% (convert 40% into decimal)
90 x 0.4 = 36
Next, subtract the discount from the total to find the sale price.
90 - 36 = 54
So, the sale price is <u>$54</u>.
Add the total of tosses: (18 + 12 = 30)
divide experimental heads by total tosses
12/30 = 2/5
as a decimal is 0.4
8 inches because a square has 4 equal sides and 32/4=8
