Well well we find the area of the triangle first:
area = 1/2 * base * height
area = 1/2 * 8 1/4 * 5 3/4
area = 1/2 * 33/4 * 23/4
area = 1/2 * 759/16
area = 759 / 32
area = 23 23/32

now if we multiply the length of the triangles we get volume because the volume of the prism is really just the sum of the areas of all the triangles that make up it's length. So:
volume = 23 23/32 * 12
volume = 276 276/32
276/ 32 = 8 5/8
volume = 284 5/8

Priya spent 1/2 of the day hiking. She was lost 5/6 of the time that she was hiking. What fraction of the day was Priya lost

Vadim26 [7]

Answer:

$\frac{5}{12}$ fraction of the day was Priya lost

Step-by-step explanation:

As per the statement:

Priya spent 1/2 of the day hiking.

⇒She spent for hiking = 1/2 of the day.

It is also given that:

She was lost 5/6 of the time that she was hiking.

⇒ $\text{She lost} = \frac{5}{6} \times \text{She was hiking}$

Substitute the given values we have;

$\text{She lost} = \frac{5}{6} \times \frac{1}{2} = \frac{5}{12}$ of the day

therefore, $\frac{5}{12}$ fraction of the day was Priya lost

Pls help me solve this

Answer:

4 kg of sugar would contain $1.2 \times 10^9$ crystals.

Step-by-step explanation:

Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.

Thus, set up a proportion as follows:

3 kg : 9 × 10⁸ = 4 kg : x

$\frac{3}{9 \times 10^8} = \frac{4}{x}$

Solve for x. Cross multiply.

$3 \times x = 9 \times 10^8 \times 4$

$3x = 36 \times 10^8$

$3x = 3.6 \times 10^9$

Divide both sides by 3

$\frac{3x}{3} = \frac{3.6 \times 10^9}{3}$

$x = 1.2 \times 10^9$

4 kg of sugar would contain $1.2 \times 10^9$ crystals.
