A patients IV bag contains 750mL. Four hours later, the IV bag contains 450mL.

Ivenika [448]

Answers:
a) 75ml/hr
b) 0ml left

Explanation:
a) 750ml - 450ml = 300ml (This is how much we know the bag drained within 4hrs)

300ml/4=75ml

so now we know the rate of drain is 75ml/hr

b) since rate is 75ml/hr:
75*6=450
450-450=0

Hence there will be no fluid left for the patient.

Find q (7q-46) (3q+6)

kap26 [50]

Answer:

$q = 22$

Step-by-step explanation:

The angle measure of a straight line is (180) degrees As given in the picture, line (AC) is a straight line, thus its angle measure is (180) degrees. Angles (ABD) and (DBC) make up line (AC). Therefore, one can conclude that the sum of angles (ABD) and (DBC) is (180) degrees. Form an equation, simplify and use inverse operations to solve for the unknown parameter (q).

$($

Substitute for the angle measures,

$(7q-46)+(3q+6)=180$

Simplify,

$10q-40=180$

Inverse operations,

$10q-40=180\\\\10q = 220\\\\q = 22$
