Answer: Alice has the prize

<u>Step-by-step explanation:</u>

$\boxed{\begin{array}{c|c|c||l}\underline{Alice}&\underline{Bob}&\underline{Carol}&\underline{Prize}\\T&T&F&\text{Alice}\\T&F&F&\text{no possible answer}\\T&F&T&\text{no possible answer}\\F&T&T&\text{no possible answer}\\F&F&T&\text{no possible answer}\\F&T&F&\text{no possible answer}\end{array}}$

Line 1:

Alice: Bob doesn’t have the prize (T) ... either Alice or Carol

Bob: I don’t have the prize (T) ... either Alice or Carol

Carol: I have the prize (F) ... either Alice or Bob

Alice is true for all of them!

Line 2:

Alice: Bob doesn’t have the prize (T) ... either Alice or Carol

Bob: I don’t have the prize (F) ... Bob

Carol: I have the prize (F) ... either Alice or Bob

<em>nobody satisfies all three statements.</em>

Line 3:

Alice: Bob doesn’t have the prize (T) ... either Alice or Carol

Bob: I don’t have the prize (F) ... Bob

Help, need to find value of x and explain how I did it (the method used)

garri49 [273]

Answer:

X = 40 degree

Step-by-step explanation:

First I would name the points whatever you do always name the points it really helps

So,

75 = a

50 = b

The middle point will be o

85 = c

X = d

Ok so,

Angle aob = y

Angle cod = z

Now,

75+50+y=180 (angle sum property)

y=180-125

y=55

Angle y = z (vertically opposite angles)

55+85+x=180 ( angle sum property )

x=180-140

Therefore x=40 degree

In higher classes you will be able to do this in your mind itself without calculation all you need is practice.

In a game of football outdoors on a cold day, a player will begin to feel exhausted after using approximately 8.0 × 105 J of int

Julli [10]

Answer:

a) How much work has he done = dW = 1.3 × 105 J

b) What is the magnitude of the heat that he has lost = dQ = -5.4 × 105 J

Step-by-step explanation:

From the first law of thermodynamics; dQ = dU + dW

dU = -8.0 × 105 J

dQ = -6.7 × 105 J

Hence, work done dW = dQ - dU

dW = -6.7 × 105 J - ( -8.0 × 105 J)

dW = 1.3 × 105 J is the work done by the player

for heat lost; from dQ = dW + dU

dU = -8.0 × 105 J and dW = 2.6 × 105 J

heat lost dQ = 2.6 × 105 J + ( -8.0 × 105 J)

dQ = -5.4 × 105 J

The negative is as a result of heat lost by the player

What is the slope of a line perpendicular to the line whose equation is x - y = 6. Fully reduce your answer. Answer: Submit Answ

NikAS [45]

Answer:

Explanation:

The standard form of an equation is expressed as y = mx+b

m is the slope

Given the equation x - y = 6

Rewrite in standard form;

-y = -x + 6

Multiply through by -1

-(-y) = -(-x) - 6

y = x - 6

Compare with the standard equation

mx = 1x

mx+b

m is the slope
