Anvisha [2.4K]

Given: Angle OQR and angle RQS form a linear pair and measure of angle OQR = $5x+5^{\circ}$ and measure of angle RQS= $11x-65^{\circ}$

To find: The measure of angle RQS.

Solution:

Since Angle OQR and RQS forms linear pair.

So, the sum of their angles is 180 degrees.

$\angle OQR+\angle RQS=180^{\circ}$

$5x+5^{\circ}+11x-65^{\circ}=180^{\circ}$

$16x-60^{\circ}=180^{\circ}$

$16x=180^{\circ}+60^{\circ}$

$16x=240^{\circ}$

$x=\frac{240^{\circ}}{16}$

$x=15^{\circ}$

Now, we will find the measure of angle RQS

$\angle RQS = 11x-65^{\circ}$

$\angle RQS = (11 \times 15^{\circ})-65^{\circ}$

$\angle RQS = 100^{\circ}$

Larry is measuring the volume of a pitcher. He uses a measuring cup that holds 2 cups and fills the measuring cup 7.5 times to f

VikaD [51]

Given,

The amount of liquid hold by measuring cup is 2 cups.

The number of times measuring cup used to fill the pitcher.

Required:

The amount of liquid pitcher hold.

The amount of liquid hold by the pitcher is,

$Amount\text{ of liquid = number of times measuring cups used}\times amount\text{ of liquid hold by measuring cup}$

Substituting the values.

$\begin{gathered} Amount\text{ of liquid =7.5}\times2\text{ cups} \\ =15\text{ cups} \end{gathered}$

Hence, the pitcher can hold 15 cups.
