Let ∠Q be an acute angle such that tanQ=0.04. Use a calculator to approximate the measure of ∠Q to the nearest tenth of a degree

Digiron [165]

We have been given that ∠Q is an acute angle such that $\text{tan}(Q)=0.04$ . We are asked to find the measure of angle Q to nearest tenth of a degree.

We will use arctan to solve for measure of angle Q as:

$Q=\text{tan}^{-1}(0.04)$

Now we will use calculator to solve for Q as:

$Q=2.290610042639^{\circ}$

Upon rounding to nearest tenth of degree, we will get:

$Q=2.3^{\circ}$

Therefore, measure of angle Q is approximately 2.3 degrees.

Bowl A contains three red and two white chips, and bowl B contains four red and three white chips. A chip is drawn at random fro

____ [38]

$\Large \text {Answer:}$

$\large \boxed {\dfrac{23}{40}}$

$\Large \text {Step-by-step explanation:}$

$\text{P}_{B}(r) = \text{P}_{A}(r) \cdot \text{P}_{B}(r) + \text{P}_{A}(w) \cdot \text{P}_{B}(r)$

$\text{P}_{B}(r) = \left (\dfrac{3}{5} \right ) \negthickspace \left(\dfrac{5}{8}\right ) + \left (\dfrac{2}{5} \right ) \negthickspace \left (\dfrac{4}{8} \right )$

$\text{P}_{B}(r) = \dfrac{23}{40}$
