Alvin takes pictures with his smartphone. Of the pictures 5/6 are animals. 3/4 of the animals are dogs. What fraction of the pic
ollegr [7]

Answer:

\dfrac{5}{8}

Step-by-step explanation:

Alvin takes pictures with his smartphone.

Of the pictures \frac{5}{6} are animals.

\frac{3}{4} of the animals are dogs.

To find which fraction of all pictures are pictures with dogs, you can simply multiply two fractions:

\dfrac{5}{6} \times \dfrac{3}{4} =\dfrac{15}{24} =\dfrac{5}{8}

<u>Another way</u> to solve this question:

Let the number of all pictures be 24 (divisible by both 4 and 6).

Then the number of pictures with animals is

\dfrac{5}{6} \times 24=5\times 4=20

and the number of pictures with dogs is

\dfrac{3}{4} \times 20=3\times 15

Hence, the fraction of pictures with dogs of all pictures is

\dfrac{15}{24}=\dfrac{5}{8}

What is the value of b2 - 4ac for the following equation? x(x 8) = 9
-BARSIC- [3]
If you would like to know the value of b^2 - 4 * a * c, you can calculate this using the following steps:

x * (x + 8) = 9
x^2 + 8x - 9 = 0
ax^2 + bx + c = 0

a = 1
b = 8
c = - 9

D = <span>b^2 - 4 * a * c = 8^2 - 4 * 1 * (-9) = 64 + 4 * 9 = 64 + 36 = 100

The correct result would be 100.</span>
