1/3(9a+b) - 1/2(4a+2b) = (1/3)(9a+b) - (1/2)(4a+2b)
                                     = (1/3).9a + (1/3)b - [(1/2).4a + (1/2).2b]
                                     = 3a + b/3 - 2a - b
                                     = a + (1/3 - 1)b
                                     = a - (2/3)b

Assume the acceleration of the object is a(t) = −9.8 meters per second per second (Neglect air resistance.) A baseball is thrown
Dennis_Churaev [7]

Answer:

height = 5.682 meters

Step-by-step explanation:

height = -9.8x^2 + 7x + 3

Find the axis of symmetry: x = -b/(2a)

a = -9.8 b = 7 c = 3

x = -7/(2*-9.8) = -7/-19.6 = .357 = x = +.357 secs is when max height occurs

Find the height, replace x with .561

height = -9.8(.357^2) + 11(.357) + 3

height = -9.8(.127) + 11(.357) + 3

height = -1.245+3.927+3

height = 5.682

Kipish [7]

To get the probability of two individual events both occurring, you have to multiply the probabilities of their individual events occurring. Therefore in this problem, the probability that a student selected at random will pass both French 101 and French 102 is 0.683 (.75 x .91). The answer is already rounded to three decimal places.

storchak [24]

Step-by-step explanation:

\tt{ 70 \degree + 61 \degree + x \degree + 61 \degree = 180 \degree} { Sum of angles of a triangle )

⟶ \tt{192 \degree + x \degree = 180 \degree}

⟶ \tt{ x  \degree = 180 \degree - 192 \degree}

⟶ \tt{x \degree =   - 12 \degree}

\red{ \boxed{ \boxed{ \text{Our \: final \: answer :  \boxed{ \tt{x =  - 12 \degree}}}}}}

Hope I helped ! ♡

A batch of snack mix made of dried fruit and nuts contain 744G of nuts the ratio of nuts to dried fruit by weight is 12 to 13 ho
mixer [17]

In a bag of snack mix:

n = nuts       d = dried fruit

n = 744g        d = ???g

Ratio Nuts/Dried fruit = 12/13

This basically means that if the mix was divided in 25 parts, 12 parts would be nuts and 13 would be dried fruits

If 744 is 12 parts then 744/12 is 1 part

744/12 = 62

1 part = 62g

there are 13 parts of dried fruit

13 x 62 = 806

744g of nuts + 806g of dreid fruit = 1550g

Answer: A batch of snack mix weigh 1550g, or 1.55kg

hope it helps :)
