Solving a mixture problem involving percent

Mathematics
1 answer:
Travka [436]3 years ago
3 0

Answer:

52%

Step-by-step explanation:

40% nuts of 5kg = 40% × 5 = 2kg

56% nuts of 15kg = 56% × 15kg = 8.4kg

total of nuts in mixture = 2 + 8.4 = 10.4kg

10.4kg of nuts in 20kg = 10.4/20 = 52%

Answer:

= x^4 -x^3 -4x^2 -3

Step-by-step explanation:

f(x) = x^4 -x^2 +9

g(x) = x^3 +3x^2 +12

We want to find f-g

(f-g) (x) = x^4 -x^2 +9 - (x^3 +3x^2 +12)

Distribute the minus sign

(f-g) (x) = x^4 -x^2 +9 - x^3 -3x^2 -12

            = x^4 -x^3 -4x^2 -3

What is the probability of randomly drawing an odd number between 24 and 33?
Studentka2010 [4]
Write out the numbers between 24 and 33:  {24, 25, 26, 27, 28, 29, 30, 31, 32, 33}

How many numbers have we here?  10.

How many of these numbers are odd?  {25, 27, 29, 31, 33}

Strictly speaking, "between 24 and 33" does not include {24, 33}.

Thus, the odd numbers between 24 and 33 are {25, 27, 29, 31}

The chances of drawing an odd number between 24 and 33 are then 4 / 10.

If, however, we omit the endpoints 24 and 33, then there are 8 numbers between 24 and 33:  {25, 27, 29, 31}

and the odds of choosing an odd number from these eight numbers is 4/8, or 1/2, or 0.50.

There are 30 students in Mrs. Taylor's kindergarten class. If there are twice as many students with blond hair as with blue eyes
weqwewe [10]

Answer:

  11

Step-by-step explanation:

Let e represent the number of students with blue eyes. Then the number of students with blond hair is 2e. The total number of students is ...

  3 + e + 2e -6 = 30

We subtracted 6 because the expressions e and 2e cause the 6 students with both blond hair and blue eyes to be counted twice.

  3e = 33 . . . . add 3 and simplify

  e = 11

11 students have blue eyes.
