Let X denote <span>the baby’s weight.
Let y represent </span>the doctor’s weight.
Let z stand for the nurse’s weight.
From the equations: x + y = 78 implies y = 78 - x
and x + z = 69 gives z = 69 - x
then we have x + y + z = 142
Substituting y = 78 - x and z = 69 - x into the equation x + y + z = 142
x + y + z = 142
x + 78 - x + 69 - x = 142
-x + 147 = 142
-x = -5
x = 5
Conclusion
<span>the baby’s weight was 5 kg</span>
Answer:
3/10 liter
Step-by-step explanation:
Assuming your statement indicates that in 4/3 liters of punch, there is 2/5 liters of water, then the proportion of water in the punch is calculated as:
(2/5)/(4/3) = (2/5)(3/4) = 3/10
So, 3/10 of a liter of water is included in each liter of punch.
Answer:
Parallel
corresponding angles theorem
NYM
AA
Step-by-step explanation: I DID IT ON EDGE!: )
We know that side NM is _________________
✔ parallel
to side XZ. If we consider side NY as the transversal, angle pairs are formed. According to the _____________
✔ corresponding angles theorem
, it follows that ∠YXZ is congruent to ∠YNM. Also, angle XYZ is congruent to angle _____________
✔ NYM
due to the reflexive property. Hence, triangle XYZ is similar to triangle NYM by the _____________
✔ AA
similarity theorem.
The correct response is A).
Mrs. Liang intends to survey patrons who utilize reading groups with children. If this doesn't include the entire patron base, which we believe it does not, her method of sampling will not accurately represent the overall patron population.
