What is 66% of $1,678.89 plus 7.5% tax?

schepotkina [342]

50% of 1,678.89 = 839.445
10% = 167.889
5% = 83.9445
1% = 16.7889
.5% = 8.39445
Therefore 66% = 1108.0674
and 7.5% = 125.91675
So the two added together is: 1233.98415
To get the percentages simply do the following
50% = divide by two
10% = divide 50% by five OR divide the original number by 10
5% = divide 10% by two or divide 50% by 10
1% = divide 5% by 5 or divide original by 100
.5% = divide 1% by two

What is the answer?

Bad White [126]

Answer:

k=3

Step-by-step explanation:

+ we note f(p)= $p^{4}+p^{2} +p -k$

+ Because of "p-1 is a factor of f(p)", that means f(p)= (p-1)* g(p)

Then we have f(1)= (1-1)*g(1)= 0* g(1)= 0

+ We replace p=1 in f(p) and we have:

f(1)=0

that means: $1^{4}+1^{2} + 1 - k=0$

then 1+1+1-k = 0, 3-k=0 or k=3

Hope that useful for you.

Three baskets contain three consecutive odd numbers of apples. There are 105 apples in total. How many apples are in each basket

galben [10]

There are 35 apples in each basket. 105/3 is 35. i got 3 by the three baskets, and 35 is a odd number which also adds up to 105.
