Answer:
-8,-29
Step-by-step explanation:
a - b = 21 --------------------------Equation 1
5a - 2b = 18 ----------------------Equation 2
From Equation 1, a = 21 + b
Putting the values of a in Equation 2 we get;
5(21 + b) - 2b = 18
105 + 5b - 2b = 18
3b = 18 - 105
b = -87 / 3
b = -29
Putting the values of b in Equation 1 we get;
a = 21 + (-29)
a = 21 - 29
a = -8

Answer:
Remain garden Area = 311 ft²
Step-by-step explanation:
Given:
Dimension of vegetable garden = 15 ft by 25 ft
Dimension of garden = 8 ft by 8 ft
Find:
Remain garden Area
Computation:
Remain garden Area = Area of vegetable garden - Area of Garden
Remain garden Area = [(15)(25)] - [(8)(8)]
Remain garden Area = 375 - 64
Remain garden Area = 311 ft²
Answer:
Volume of the solid is 377 cm³.
Step-by-step explanation:
Volume of the cylinder =
Here, r = radius of the cylinder
h = Height of the cylinder
By substituting the values in the formula, (r = 4 cm and h = 10 cm)
Volume of the cylinder =
= 160π
Since one fourth of the cylinder is removed,
Volume of the remaining cylinder = 160π -
= 160π - 40π
= 120π
= 120(3.14)
= 376.8 cm³
≈ 377 cm³
Volume of the solid is 377 cm³.
