Answer:3/20
Step-by-step explanation:
Fraction of total area mowed = (3/5) + (1/4) = 17/20
Therefore fraction of total area left = 1 - (17/20) = (20/20) - (17/20) = 3/20
Answer:
E=20H
Step-by-step explanation:
E =20 when H=1
there fore the amount he receives per working time will be 20*H
Answer: 
Step-by-step explanation:
Here w shows the number of weeks and t shows the total amount in w weeks.
Since, the initial amount he paid to her = $ 50
After that he paid $ 5 per week.
Thus, the total extra amount he paid = 5 w
⇒ The total amount he paid to her = 50 + 5 w
⇒ t = 50 + 5 w
Which is the required relation between the total amount paid(t) and the number of weeks (w) Jake will take to pay Luna.
<span>4. Simplify the expression.
sine of x to the second power minus one divided by cosine of negative x</span>
<span>(1−sin2(x))/(sin(x)−csc(x))<span>
</span>sin2x+cos2x=1</span>
<span>1−sin2x=cos2x<span>
</span>cos2(x)/(sin(x)−csc(x))</span>
<span>csc(x)=1/sin(x)</span>
<span>cos2(x)/(sin(x)− 1/sin(x))= cos2(x)/((sin2(x)− 1)/sin(x))</span>
<span>sin2(x)− 1=-cos2(x)</span>
<span>cos2(x)/(( -cos2(x))/sin(x))
=-sin(x)</span>
