Let the number of islands visited be x and that peninsulas be y
thus,
x+y=19
⇒y=19-x.........i
if he skydives twice in islands and thrice in peninsulas, then the total number of skydives will be:
2x+3y=45.....ii
substituting i in ii we get:
2x+3(19-x)=45
2x+57-3x=45
putting like terms together we get:
2x-3x=45-57
-x=-12
therefore
x=12
and
y=19-x=19-12=7
hence the number of islands visited was 12 and that of peninsulas was 7
Your answer is C) Translation
Answer:
62.5
Step-by-step explanation:
1. convert percent value to decimal
30.00/100=.3
2. turn problem into equation where x equals the original price
x*.3=18.75
3. solve
(x*.3=18.750)/.3
x=62.5
A student pays for 8.9 pounds of apples with a 10$ bill. Its $1.09 per pound. How much change does the student receive? What do you do first to solve the problem?
Answer:
$0.299
Step-by-step explanation:
Given that :
Pounds of apple purchased = 8.9 pounds
Price per pounds of apple = $1.09
Bill issued = $10
First, we calculate the total cost of 8.9 pounds of apple :
(Number of pounds * price per pound)
($8.9 * 1.09) = $9.701
Amount of Change :
Bill issued - total cost
$10 - $9.701
= $0.299
HL(c) = a² + b² = c²
c = 9
c² = 18
√18= 4.24264068712
So! since this triangle is a "45° 45° 90°"
The two short legs are equivalent
meaning each side equals; <span>4.24264068712</span>
