Answer:
1350 cm³
Step-by-step explanation:
we have given that,
• Height of A = 10 cm.
1350
• Volume of A = 400cm³.
• Height of B = 15 cm.
• Both A and B solids are similar.
from above told concept we get,
→ V(A) / V(B) = (Height of A)³ / (Height of B)³
Putting all given values we get,
→400/ V(B) = (10)³/(15)³
→400/V(B) = (1000/3375)
→ V(B) = (400*3375) / 1000
→ V(B) = (4 * 3375) / 10
→ V(B) = 1350 cm³. (Ans.)
Hence, Volume of B will be 1350 cm³.

Answer:
4 cm
Step-by-step explanation:
The area of the triangle is half the area of the rectangle. The base of the triangle is the diameter of the circle, 14 cm. So the height is found from ...
A = 1/2bh
(56 cm²)/2 = 1/2(14 cm)h
h = (28 cm²)/(7 cm) = 4 cm
The height of triangle ADC is 4 cm.
Making 1 necklace takes her 0.5 hours, so making x necklaces, will take her 0.5x hours.
Making 1 bracelet takes her 1 hour, so making y bracelets, will take her 1*y=y hours.
So in total, she needs to work for 0.5x + y hours.
Since she has fewer than 20 hours, 0.5x + y must be smaller that 20.
Thus, we have 0.5x + y<20
Answer:0.5x + y<20
