Answer:
$2.80
Step-by-step explanation:
Divide 2.45 by 7 to get the cost of 1 orange which is $0.35. Multiply that cost by 8 to get the cost of 8 oranges and your final answer which is $2.80.
Considering that it is allowed to repeat the digits in the three-digit code, we have,
10 x 10 x 10 ways
which is equal to 1000 ways.
For the scenario that only even numbers without repetition can be included, we have,
5 x 3 x 1 ways
which is equal to 15 ways.
The probability is therefore 15/1000 or 3/200.
Answer:
d=20
Step-by-step explanation:
To find the distance between 2 points we use the distance formula
d = √(x2 - x1)²+(y2 - y1)²
The given points are (x1= -8, y1 = -6) and (x2 = 4, y2 = 10).
Substitute the given points into the distance formula.
d = √(4 + 8)²+(10 +6)²
d = √144+252
d= √400
d = 20
Let's say the price of one book is the variable x
Therefore, Alana is 5x and Petra is 4x
Angus bought 19x, but since he had a $10 discount, it is 19x-10
Combined, Alana and Petra is 5x+4x, but since it says Angus spent $5 more, it would be 5x+4x+5
Therefore, we get the equation:
19x-10=5x+4x+5
19x-10=9x+5
10x=15
x=15/10 or 3/2 which equals 1.5
Therefore, one book costs $1.5
