$\boxed{\text{3. }\dfrac{7\pi}{30} \text{; 4. } -20^{\circ}\text{; 5. } -\dfrac{720^{\circ}}{\pi}}$

Step-by-step explanation:

Question 3

$42^{\circ} \times \dfrac{\pi}{180^{\circ}} = \boxed{\dfrac{7\pi}{30}}$

Question 4

$-\dfrac{\pi}{9} \times \dfrac{180^{\circ}}{\pi}= \boxed{-20^{\circ}}$

Question 5

$-4\times \dfrac{180^{\circ}}{\pi}= \boxed{-\dfrac{720^{\circ}}{\pi}}$

Answer:310

Step-by-step explanation:

so use pemdas

Parenthesis,exponents multiplication, division , addition, and subtraction order

231*5-16+101)/4

first i'm assuming the parenthesis is over the whole thing

that the question should look like (231*5-16+101)/4

first parenthesis, 231*5=1,155

1,155-16=1,139+101= 1,240

1240/4= 310.
