Answer:

b = 14

Step-by-step explanation:

3b/7 -1 = 5

3b/7 = 6

3b = 6x7 = 42

b = 42/3

b = 14

Answer:

b = 14

Step-by-step explanation:

3b/7 - 1 = 5

Add 1 to both sides.

3b/7 = 6

Multiply both sides by 7 to cancel the fraction.

3b = 42

Divide both sides by 3 to get b by itself.

b = 14

Proof:

3b/7 - 1 = 5

Insert variable.

3(14)/7 - 1 = 5

Multiply.

42/7 - 1 = 5

Divide.

6 - 1 = 5

Subtract.

5 = 5

Can someone help me
marshall27 [118]

Answer:

16682.7 cm³

Step-by-step explanation:

The total volume is the volume of the cone plus half the volume of a sphere:

V = ⅓ π r² h + ½ (4/3 π r³)

V = ⅓ π r² h + ⅔ π r³

V = ⅓ π r² (h + 2r)

Given that r = 4.15 cm and h = 10.2 cm:

V = ⅓ π (4.15)² (10.2 + 2×4.15)

V ≈ 333.65

The volume needed for 50 cones is therefore:

50V ≈ 16682.7 cm³
