Answer:
X=140
Step-by-step explanation:
<em>Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees</em>
<em>The attachment you are showing us shows that we already know two angles</em>
<em>(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360. </em>

X+70+60+90=360
X=360-70-60-90
X=140
Let the walker’s speed be W, then the biker’s is W+1.5W=2.5W. Difference in speed is 1.5W. Distance=speed times time, so 12.5=1.5W×1.5=2.25W, and W=12.5/2.25=1250/225=50/9=5.56 mph. The biker’s speed is 2.5W=125/9=13.89 mph to 2 Dec places.
(Note: “1.5 times faster than a walker’s speed” could not reasonably mean the biker’s speed=1.5W because this would give W=16.67 mph, which is very fast for a runner, let alone a walker (!), and a biker’s speed of 25mph.)
There are 100 pence in a Pound. So we have to divide 25 pence over this pound, or over 100 pence: 25/100 is 1/4, so 25 Pence is one forth of a Pound (or 25 % in percentages):
Answer:
0.5 week
Step-by-step explanation:
The time spent by a pound of meat in this system is given by the average number of pounds of meat on inventory (2500 pounds) divided by the average weekly meat consumption (5000 pounds per week).
The time, in weeks, is:
The average time spent by a pound of meat in production is 0.5 week.
