Answer:
44
Step-by-step explanation:
Given that Krutika gets 33 sweets which is 3 parts of the ratio.
Divide this amount by 3 to find the value of one part of the ratio
33 ÷ 3 = 11 ← 1 part of the ratio, thus
David gets 1 × 11 = 11 sweets and
Mark gets 5 × 11 = 55 sweets, thus
55 - 11 = 44 ← number of sweets Mark gets over David
Step-by-step explanation:
11. B - stop -horizontal line, distance does not change.
12. A - Smallest slope=smallest speed .
13. C - largest slope = fastest speed
14.Speed (at D) = 60/3 =20 km/h
15. 60 km
5.8
2.4 - 3.4 = 5.8
the boats are 5.8 units apart.
x= -4

xy = 32 makes y = 32/x
z² = (32/x)² + (x/2)²
<span>Isolate z
</span>z = 32/x + x/2
Find dz/dx
fr(z) = (x² - 64)/ (2x²)
<span>Set z' = 0, algebraically solving for x having
</span>x +- 18
<span>Since you cannot have a dimension of -8, the only answer for x is 8.
</span>
<span>Go back to the original area equation; 32 = xy and plug in x making
</span><span>32 = 8y
</span><span>y = 4</span>
