Answer:

30 dollars

Step-by-step explanation:

The question states that if an even number comes up then Joe will win 5 times of the number that shows up for example, if 2 comes up he will win 5×2 dollars i.e., 10 dollars. If an odd number shows up he will lose 10 times the number which i.e. if 1 shows up he will lose 1×10 = 10 dollars

It says in the question that Joe tosses a 3 which is an odd number so he will lose 10 times of 3

So he will lose 10×3 = 30 dollars.

Answer:

If Joe tosses a 3, he will lose 30 dollars.

Step-by-step explanation:

To express this in a general form we can use functions which will be expressed in terms of the number tossed.

  • We know that if the number that turns up is <u>even,</u> he will gain 5 times the number.
  • Therefore, the function for when the number x is even would  be <u>f(x) = 5x </u>

  • On the other hand, if the number is <u>odd,</u> he will lose 10 times the number.
  • Therefore, the function for when the number x is odd will be f(x) = -10x

Finally Joe tosses a 3, 3 is an odd number, therefore the function we will use will be f(x) = - 10x

f(3) = -10(3) = -30

Therefore, Joe will lose 30 dollars.

What is the distance (in units) between points C and D? Round your answer to the nearest hundredth. A. 4.54 B. 5.00 C. 5.83 D. 3
Kryger [21]

Answer:

5.83 = CD

Step-by-step explanation:

We can use the pythagorean theorem to solve

The legs are the x and y distances

x = (1- -4) = 5 units and y = 3 units

a^2+ b^2 = c^2

5^2 + 3^2 = c^2

25+9 = c^2

34 = c^2

Taking the square root of each side

sqrt(34) = c  which is the distance from C to D

5.830951895 = CD

5.83 = CD

Answer:

70

Step-by-step explanation:

7^2 - ( 6-3^3)

PEMDAS

Parentheses first

7^2 - ( 6-3^3)

The exponent in the parentheses first

7^2 - ( 6-27)

7^2 - ( -21)

Now the exponent

49 - (-21)

Now subtract

49 +21

Hey there!


Andrea makes 20% more than Cassidy.

Work:

10 x 0.20 = 2

10 - 2 = 8


So that proves it is 20%.
