F is sometimes Positive and sometimes negative on the interval
Answer:
x = 48
Step-by-step explanation:
first you would add them together and set it equal to 180( because a straight line is 180 degrees): 3x - 12 + x = 180
Then you add like terms( the x's): 4x - 12 = 180
now add 12 to both sides: 4x = 192
now divide by 4 on both sides x = 48

Answer:
5.25 hours
Step-by-step explanation:
The calculation of the time needed to schedule for all seven applications is shown below:
Since 3 by 4 is required of an hour to meet you show them
i.e.
= 3 ÷ 4 of an hour
= 3 ÷ 4 × 60 minutes
= 45 minutes
Now for seven applications, the time would be
= 7 × 45 minutes
= 315 minutes
And, one hour = 60 min.
So, the time required is
= 315 minutes ÷60 minutes
= 5.25 hours
Answer:
<em>PZ = 15</em>
Step-by-step explanation:
<u>Similar Triangles</u>
Two triangles are similar if all of their corresponding side lengths are proportional to the same scale factor.
It's given triangles TPR and XPZ are similar, thus we can find the scale factor by comparing two corresponding sides with known lengths.
Sides TR and ZX are corresponding and the proportion of their side lengths is 15/9. The same proportion must be satisfied by the sides TP and XP:
PX and PZ are congruent, thus:
Calculating:
PZ = 15
