Answer:
6(9r-7)
Step-by-step explanation:
54r–42
Both 54 and 43 can be divided by 6
54/6 =9 and 42/6 =7
6*9r - 6*7
Factor out the 6
6(9r-7)
Step-by-step explanation:
35. 1000 m / 1 km = 10³
Move the decimal point 3 places to the right.
36. 100 cm / 1 m = 10²
Move the decimal point 2 places to the right.
37. 1 mm / 1000 μm = 10⁻³
Move the decimal point 3 places to the left.
38. 1 km / 1000 m × 1 m / 100 cm = 10⁻⁵
Move the decimal point 5 places to the left.
39. 1 Mm / 10⁶ m × 1 m / 10⁶ μm = 10⁻¹²
Move the decimal point 12 places to the left.
40. 100 cm / m × 1000 m / km = 10⁵
Move the decimal point 5 places to the right.
In order to find the volume you need the height.
Surface area = π r² + base x height or width x length
1850 = 3.14 × 9² + radius × 2 x π x height
1850 = 254.34 + 9 × 2 × 3.14 × height
1850 = 310.86 × height
To find the height you have to divide the surface area by the part I bolded
Height = 1850 ÷ 310.56
Height ≈ 6
Volume of a cylinder = πr²×height
= 3.14 × 9 × 9 × 6
Volume =1526.04
Nearest whole number would be 1526
Answer: You could have an infinite amount of triangles with these measurements.
Unless, you are missing something in the problem, there is not enough information that would narrow it down to a single triangle. Angle A is fixed and the height is fixed. However, Angle B and C could be anything as long as they formed a triangle and had side a of 15 in between them.
