Answer:
112.5 minutes
Step-by-step explanation:
Working together, Daniel and Donnie can clean the llama pen in 50 minutes. On his own, Daniel can clean the pen in 90 minutes.
Let the number of minutes it takes Donnie to clean his Ilama pen be represented by: x
Hence, we have the expression:
1/90 + 1/x = 1/50
The Lowest Common Denominator for the left hand side = 90x
Hence:
x + 90/90x = 1/50
Cross Multiply
50(x + 90) = 90x
50x + 4500 = 90x
Collect like terms
4500 = 90x - 50x
4500 = 40x
Divide both sides by 40
x = 4500/40
x = 112.5 minutes
Therefore, it takes Donnie 112.5 minutes to clean the llama pen on his own.
Answer:
2√3
Step-by-step explanation:
circle pass (h,k): (x-h)² + (y-k)² = r²
radius = √12 = 2√3
Part A:
Phone A has a $8.75 discount
$175*0.05=$8.75
Phone B has a $40.00 discount
$200*0.20=$40
Part B:
Phone A is $166.25
$175-$8.75=$166.25
Phone B is $160.00
$200-$40=$160
Part C:
Phone B costs less after the discount
Part D:
No, sales tax is applied to the discounted/final price, so both prices will increase by 6%. Phone B will still be cheaper.
