Answer:

(a) 1/2
(b) 1/3

Step-by-step explanation:

(a) 3 of the 6 numbers on the die are even, so the probability that one of them will show is 3/6 = 1/2.

(b) 2 of the 6 numbers on the die are less than 3, so the probability that one of them will show is 2/6 = 1/3.

A car is traveling down a highway at a constant speed, described by the equation d=65t, where d represents the distance, in mile

Alexxx [7]

Answer:

Step-by-step explanation:

We are given an equation d = 65 t, where d represents the distance, in miles, that the car travels at this speed in t hours.

We know distance, speed and time relation

d = s * t.

Where d represents the distance, that the car travels at this speed in t at the speed s.

If we compare that relation with the given equation, we can see s = 65.

So,

a) The 65 tell us speed of 65 miles per hour in this situation.

b) Second part seems to be incorrect. Please check it again.

c) We are given distance = 26 miles.

Plugging d= 26 in the given equation.

26 = 65 t

Dividing both sides by 65, we get

26/65 = t

t= 0.4 hours.

So, it takes 0.4 hours or 0.4 * 60 = 24 minutes o travel 26 miles at this speed.

Please help me on dis question

lara [203]

Answer:

a) See below

b) $\huge\boxed{\sf Area\ of\ each\ triangle = 62.4\ in.\²}$

c) $\huge\boxed{\sf Area\ of\ the\ table = 374.4\ in.\²}$

Step-by-step explanation:

We can draw 3 lines from A to D, B to E and F to C such that all of the lines pass from the center. This will form 6 equal (congruent) triangles.

$\rule[225]{225}{2}$

Area of each triangle = 1/2 (Base)(Height)

Where Base = 12 in. and Height = 10.4 in.

Area = 1/2 (12) (10.4)

Area = 6 (10.4)

Area of each triangle = 62.4 in.²

$\rule[225]{225}{2}$

Since the table is mage up of 6 equal triangles:

So,

Area of the table = 6 (Area of each triangle)

Area of the table = 6 (62.4)

Area of the table = 374.4 in.²

$\rule[225]{225}{2}$

Hope this helped!
