Answer:

it would be 60 degrees

Step-by-step explanation: Every 5 minutes on a clock there is a big number, and there are 12 of those. 360/12 is 30 degrees, so every hour, the hour hand moves 30 degrees.

Hamdan says that when you add fractions with the same denominator, you can add the numerators and keep the same denominator. Is

Elina [12.6K]

Answer:

Yes, Hamdan is correct.

Step-by-step explanation:

Let the two fractions are q/r and s/r.

Here, the denominator is same for both the fractions.

So, as we add them, add the numerators and the denominators remains same.

$\frac{q}{r}+\frac{s}{r}\\\\=\frac{q + s}{r}$

For example

$\frac{3}{5}+\frac{4}{5}\\\\=\frac{3 + 4}{5}\\\\=\frac{7}{5}$

So, Hamdan is correct.

Find the tangent of each angle that is not the right angle. Drag and drop the numbers into the boxes to show the tangent of each

omeli [17]

Answer:

tan D = $\frac{6}{11}$ or 0.545

tan F = $\frac{11}{6}$ or 1.833

Step-by-step explanation:

To find tangent is always $\frac{opposite}{adjacent}$

so the opposite of angle D is line EF which is 4.8 and the adjacent side is line ED which is 8.8 so $\frac{4.8}{8.8}$ which is $\frac{6}{11}$ or 0.545
