Answer/Step-by-step explanation:
Unit cost of apple = $2 let each
Unit cost of orange = $1 per each
a. Cost of 6 apples = 6 × $2 = $12
Cost of 3 oranges = 3 × $1 = $3
b. Cost of 4 apples = 4 × $2 = $8
Cost of 4 oranges = 4 × $1 = $4
c. Cost of 5 apples = 5 × $2 = $10
Cost of 4 oranges = 4 × $1 = $4
d. Cost of 8 apples = 8 × $2 = $16
Cost of 2 oranges = 2 × $1 = $2
Answer: x = $25.89
Step-by-step explanation:
This is a two step problem. First we need to determine the number of gallons the car uses to drive the 250 miles:
250/28 ≈ 8.93 gallons
Then we just multiply the number of gallons by the price:
8.93 x 2.90 = $25.90
Alternate solution: Use a proportion. Since 1 gallon costs $2.90 and produces 28 miles, we can set up the following proportion:
2.90/28 = x/250
Cross-multiply and solve:
28x = 725
x = $25.89 (There is a one cent difference due to a rounding error in the first solution. This solution avoids that error.)
Answer:
If 12 and 14 are both side lengths then we solve for the hypotenuse:
hypotenuse^2 = 12^2 + 14^2
hypotenuse^2 = 144 + 196
hypotenuse^2 = 340
hypotenuse = sq root (340) = 18.4390889146
If hypotenuse = 14, then third side equals:
(3rd side)^2 = 14^2 - 12^2
(3rd side)^2 = 196 -144
(3rd side)^2 = 52
3rd side = sq root (52) = 7.2111025509
Step-by-step explanation:
Hello there,
Actual price = $100
After 10% discount = $100 - (10/100 x 100)
= $90
After 15% discount = $90 - (15/100 x 90)
= $76.50
Final cost - $76.50
Hope this helps :))
