Answer:
a = u - k + b
Step-by-step explanation:
u = a + k - b
u - k + b = a+ k - b - k + b
u - k + b = a
Answer:
1 or 2
Step-by-step explanation:
If you want it equally then it would be 1. The reason for this is cause you will have to divide 3 and 2 by 75 to get 25 and 37. So only 1 can go into both numbers equally. If you want a little bit over you would get 2 cause you would do the same steps like for 1 but you would subtract the 37 and 25 to get the remainder of 12 so it would be 12

Answer:
- slant height: 2.1 cm
- pencil area: 51.12 cm^2
Step-by-step explanation:
The slant height (s) is the hypotenuse of the right triangle with legs of 2 cm and 0.5 cm.
s^2 = 2^2 + 0.5^2 = 4 + 0.25
s = √4.25 ≈ 2.0616 ≈ 2.1
The slant height is about 2.1 cm.
__
The surface area of the whole pencil is the sum of the areas of the circular base, the lateral area of the cylindrical part, and the lateral area of the cone.
A = πr^2 +2πrh +πrs
A = πr(r +2h +s) = (3.14)(0.5 cm)(0.5 cm + 2×15 cm + 2.1 cm)
A ≈ 51.12 cm^2
The area of the whole pencil is about 51.12 cm^2.
