Answer: D = 40 / C
Step-by-step explanation:
total amount of soil divided by soil in each bag. To find the total amount of soil multiply number of flower boxes (10) by amount of soil each box holds (4 kilograms). So, number of bags (D) equals 40 divided by kg of soil in each bag (C)
Answer:
Step-by-step explanation:
All the angels of a triangle always add up to 180
(2x-15)+(x+43)+x = 180
Multiple the numbers inside the parentheses first
-30x+43x+x = 180
Add common terms
14x = 180
Divide by 14 to get the variable by itself
x ≈ 12.86
1) find the are of the circle: πr²
2) find the area of each triangle: (base x altitude)/2
3) subtract the triangles from the circle are
1) area of circle:π.5² = 25 π
2) Area of the triangle = (6 x 4)/2 =12 cm². We also notice that both triangles are congruent SSS (6,5 & 5), so the total surface of the 2 triangles = 24 cm²
3) (25π - 24) cm² is the answer
