(5-2) = 3 Do parenthesis.
7 × 3 = 21 Multiply with what we got after doing the parenthesis.
9 + 21 = 30 Add with what we had left.
30
Hope this helps!

Answer:
Step-by-step explanation:
Since, the radius of the balloon 4 days ago = 5,
⇒
Now, if the radius is decreased by 0.5 cm each day,
Then the current radius of the balloon = 5 - 4 × 0.5 = 5 - 2 = 3 cm,
⇒
Thus, the ratio of the current volume of the balloon to the volume of the balloon 4 days ago
⇒ Option A is correct.

Answer:cos theta = -(1)/2; tan theta = sqrt(3)
cos theta = -(1)/2; tan theta = -1
cos theta = (sqrt(3))/4; tan theta = -2
cos theta = 1/2; tan theta = sqrt(3)
cos theta = 4/3
