Answer:4/24

Step-by-step explanation: dice has 6 sides and you will be rolling it 4 times so you multiple that which gets you 24 and since you roll the dice 4 times you might get 6, 4times since there’s only one 6 each time

Every time you roll you have a 1/6 chance so rolling 4 times you have a 6x4= 24 and 1x4=4 so you have a 4/24 chance of getting a 6

The distance traveled by a falling object is given by the formula d = 0.5gt2 where d = distance, g = the force of gravity, and t

Alina [70]

D = 0.5gt^2
2d = gt^2
g = 2d/t^2

when t = 10 s, and d = 490 feet,
g = 2(490)/10^2 = 980/100 = 9.8 feet/s

What is the area of this polygon? 28.5 units² 34.5 units² 37.5 units² 40.5 units² 6 sided polygon on a coordinate plane with ver

LUCKY_DIMON [66]

Answer:

Option B.

Step-by-step explanation:

The given vertices of the polygon are (-6,-2),(-5,1),(-1,4),(1,1),(5,3),(1,-2).

We need to find the area of the polygon.

Plot the given vertices and on a coordinate plane and draw the polygon. Divide the polygon in 4 parts as shown below.

Area of rectangle is

$A=length\times width$

Area of triangle is

$A=\dfrac{1}{2}\times base\times height$

Area of each figure is

$A_1=\dfrac{1}{2}\times 1\times 3=1.5$

$A_2=\dfrac{1}{2}\times 6\times 3=9$

$A_3=\dfrac{1}{2}\times 4\times 3=6$

$A_4=6\times 3=18$

Area of polygon is

$A=A_1+A_2+A_3+A_4$

$A=1.5+9+6+18=34.5$

The area of polygon is 34.5 units².

Therefore, the correct option is B.

What is the value of x in the equation 4(2x + 10) = 0? (1 point)

miskamm [114]

Answer:

x = -5

Explanation:

4(2x + 10) = 0

[ Simplify both sides of the equation ]

4(2x + 10) = 0

(4)(2x) + (4)(10) = 0 [Distribute]

8x + 40 = 0

[ Subtract 40 from both sides ]

8x + 40 − 40 = 0 − 40

8x = −40

[ Divide both sides by 8 ]

8x / 8 = −40 / 8

x = -5
