Answer:
the answer is 8:5
Step-by-step explanation:
The doctor's cost for a set of scrubs is $47.60
Given:
cost = $34
mark-up = 40%
Mark up based on cost:
$34 * 40%/100% = $13.60 mark up
New price or doctor's cost:
$34 + 13.60 = $47.60
It can also be computed this way.
$34 * 140%/100% = $47.60
Answer:
Altitude of cylinder = 10 cm
Step-by-step explanation:
Given:
lateral surface area of cylinder = 90 cm²
Circumference of base = 9 cm
Find:
Altitude of cylinder
Computation:
Circumference of base = Circumference of cylinder
So,
2πr = 9
lateral surface area of cylinder = 2πrh
2πrh = 90
We know that; 2πr = 9
So,
9(h) = 90
h = 90 / 9
Altitude of cylinder = 10 cm
Hmmm, just follow what ur gut thinks ifthat make sense
