Answer:

922.832

Step-by-step explanation:

We are asked to multiply 27.4 by 33.68.

We can write our given problem as a multiplication problem without decimal as:

3368

X 274

13472

235760

673600

922832

We can see that both numbers has three digits after decimal, so we will plot a decimal three digits from the right as:

$27.4\times 33.68=922.832$

Therefore, our required product is 922.832.

Answer:

2.5 hours

Step-by-step explanation:

The product of speed and time is distance. If the distance is the same, then time is inversely proportional to speed. At 60/50 = 6/5 times the speed, the return trip will take 5/6 times the time:

(5/6)(3 hours) = 2.5 hours . . . time for return trip

1. The value of k for which equation 9x2 + 8xk+8 = 0 has equal roots is:

Nesterboy [21]

Answer:

Option C

+ or - 3

Step-by-step explanation:

A quadratic equation will have equal roots if its Discriminant is equal to zero.

the discriminant in this case is $b^{2}- 4 ac$

considering the equation,

$9x^{2} + 8xk+8 = 0$

a = 9, b= 8k, c=8

Replacing the variables in the original equation with their respective values, we will have:

$8k^{2}- 4 \times 9 \times 8=0\\64k^{2}=288\\k=\sqrt{288/64} =\sqrt{9/2}$

Note: The values of k are meant to be + or -2.12 as seen from the workings

However, these are not in the options given. the closest choice to it

is + or - 3

Answer: 13.375% per year

Explanation:

1) Depreciation is the loss of value: $ 20,000.00 - $ 14,650.00 = $ 5,350

2) The percent of depreciation is amount of the depreciation divided by the value of the car when purchased, times 100.

That is (5,350 / $ 20,000) * 100 = 26.75 %

2) The rate is percent of depreciation per year:

depreciation rate = % of depreciation / number of years = 26.75% / 2 = 13.375% per year.
