Answer:
The second option or B
Step-by-step explanation:
The approximate total mass= number of atoms * weight of an atom.
The approximate total mass=3.06 10²³ atoms. (1.67 10⁻²⁴ grams/1 atom)=
=0.51102 g ≈ 0.51 g
Answer: the approximate total mass is 0.51 grams.
Y = 3x^2 + 7 is the equation of the parabola
The answer would be 10.
Simplifying5 + 3(5) + -5(4 + -2)
Multiply 3 * 55 + 15 + -5(4 + -2)
Combine like terms: 4 + -2 = 25 + 15 + -5(2)
Multiply -5 * 25 + 15 + -10
Combine like terms: 5 + 15 = 2020 + -10
Combine like terms: 20 + -10 = 1010
Answer:
(1) True
(2) False
(3) True
(4) True
Step-by-step explanation:
(1) It is true Darla can use either the height of 6 m or 5 m to find the area of the triangle because Darla already knows the measurement of a side of the triangle. Multiplying the side by either of the heights divided by 2 gives the area of the triangle.
(2) It is false they will find the same area of the triangle.
Area of triangle = (side×height)/2
Darla's area of the triangle = (9×6)/2 = 54/2 = 27 m^2
Rico's area of the triangle = (7.5×5)/2 = 37.5/2 = 18.75 m^2
(3) It is true they will find the same area of the triangle.
Rico's area of the triangle = (7.5×6)/2 = 45/2 = 22.5 m^2
Darla's area of the triangle = (9×5)/2 = 45/2 = 22.5 m^2
(4) It is true the area of the triangle is 22.5 square meters as shown in part (3) above.
