When you multiply a vector by a scalar, you distribute the scalar to the vector's components:

k\langle a,b\rangle=\langle ka,kb\rangle

In this case,

\mathbf u=\langle25,-30\rangle\implies-\dfrac25\mathbf u=\langle-10,12\rangle

so the answer is G.

Miranda found out that there are 20 drops in 11 mL of medicine. She measured 15 drops of medicine into a measuring cup. How many
andreyandreev [35.5K]

Answer: Her measuring cup has 8.25 mL of medicine.

Step-by-step explanation:

As per given,

In 11 mL of medicine, there are 20 drops.

That means quantity in 1 drop = \dfrac{11}{20} mL

Now , the quantity in 15 drops = 15 x quantity in 1 drop

= 15\times\dfrac{11}{20}

=\dfrac{33}{4}

= 8.25 mL

Hence, her measuring cup has 8.25 mL of medicine.
