Answer:
425 mm
Step-by-step explanation:
The ratio of compound A to compound B is 5 is to 6.
So, we can say that the total ratio is of 11 parts (5+6=11).
<em><u>If the chemist wants a total of 935 mm of the drug, then each of the 11 parts are worth:</u></em>
<em>From the ratio, we know that Compound A is 5 parts. So:</em>
425 mm of Compound A is needed.
Answer:
(2) a rotation by about the intersection of the lines creating the vertical angles.
Step-by-step explanation:
Rigid motion are a set of transformation procedure to change the dimension, orientation or size of a given figure or shape. It involves rotation, translation, reflection and dilation.
Vertical angles are formed when two straight lines intersect to form angles. But two opposite angles called vertical angles are equal. To prove that vertical angles are equal; a rotation by about the intersection of the lines creating the vertical angles is required.
