To answer the problem given above, divide the difference of the prices by the original price and multiply the answer by 100%. This is,
((22450 - 19450) / 19450) x 100% = 15.42%
Therefore, the percentage markup of the new car is approximately 15.42%.
Answer:
90
Step-by-step explanation:
There are 10 people who can be picked for the first position, which leaves 9 people who can be picked for the second position.
10 × 9 = 90
You can also use permutations.
₁₀P₂ = 90
Answer: There are no real number roots (the two roots are complex or imaginary)
The discriminant D = b^2 - 4ac tells us the nature of the roots for any quadratic in the form ax^2+bx+c = 0
There are three cases
- If D < 0, then there are no real number roots and the roots are complex numbers.
- If D = 0, then we have one real number root. The root is repeated twice so it's considered a double root. This root is rational if a,b,c are rational.
- If D > 0, then we get two different real number roots. Each root is rational if D is a perfect square and a,b,c are rational.
Answer:
c) (0.40)(0.35)x + (0.45)(0.64)y = 1200
Step-by-step explanation:
<u>Profit on each tulip bulb is:</u>
<u>Profit on </u><u>x</u><u> amount of tulip bulbs:</u>
<u>Similarly, profit on </u><u>y</u><u> amount of daffodil bulbs is:</u>
<u>Since the target is $1200, the required equation is:</u>
- (0.40)(0.35)x + (0.45)(0.64)y = 1200
Correct answer option is C)
