A man can mow his lawn in 4 hours. His son can do the job in 3 hours. If the son takes over an hour after his father, how long w

cupoosta [38]

Determine part of the job that has been done by the father.
The father did for an hour before the son took over, and he could complete the job within 4 hours. That means he already did $\frac{1}{4}$ of the job.
The finished job = $\dfrac{\text{time of work}}{\text{time needed to do whole job}}$
The finished job = $\dfrac{\text{1 hour}}{\text{4 hours}}$
The finished job = $\dfrac{1}{4}$

Determine part of the remaining job
remaining job = 1 - the finished job
remaining job = 1 - $\frac{1}{4}$
remaining job = $\frac{3}{4}$
The remaining job for the son is 3/4 of the job

Determine time needed to do 3/4 of the job
time needed = $\frac{3}{4} \times \text{time needed to do whole job}$
time needed = $\frac{3}{4} \times 3$
time needed = $\frac{9}{4}$
time needed = $2 \frac{1}{4}$ hours
time needed = 2 hours + 15 minutes

To finish mowing the lawn, the son needs 2 hours and 15 minutes

Based only on the information given in the diagram, which congruence

vovangra [49]

Answer:

Step-by-step explanation:On the given diagram you see two right triangles with equal hypotenuses and pair of equal angles.

Based only on the information given in the diagram you can conclude that triangles are congruent by HA theorem (the HA theorem states that "if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent").

Also you can conclude that triangles are congruent by AAS Postulate (the AAS Postulate states that "if two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent").
