Answer:

I believe 2 is b or C. 3.c

Step-by-step explanation:

Since there is more heads than tails, we know it's going to be bigger. Since there is not an exact half, and heads is 8, it is going to be one of the 0.533.

Since there are 52 cards in a real deck, there's only 4 cards of each. Since you almost double the amount of cards, it's going to be more than 4, but less than at least 15.

Which student solved the equation w/13.5 = 9.7 correctly?​
Nataliya [291]

Answer:

Kwan's work

Step-by-step explanation:

The given equation is:

\frac{w}{13.5}=9.7

We multiply both sides by 13.5 to obtain:

\frac{w}{13.5}\times 13.5=9.7\times 13.5

We simplify to get;

w=9.7\times 13.5

We multiply out the RHS to get:

w=130.95

Does anyone know this??
STALIN [3.7K]
Hi there! The answer is C.

Explanation:
We have the following equation:

\frac{8}{15} = \frac{x}{6}
To solve this type of equation (with an x in the denominator of a fraction) we must cross-multiply the numerator and the denominator.

15 \times x = 8 \times 6
Multiply

15x = 40
Divide both sides by 15.

x = \frac{40}{15} = 2 \frac{2}{3}
~ Hope this helps you!

Hi, can you please help me answer this direct proportion question?
Oksanka [162]

Answer:

X = 100

Step-by-step explanation:

  • In proportion questions, they want you to multiply one of the sides by a variable, (i usually represent it with K) and then change the proportion sign to an equal.
  • This is because proportional means they have a ratio between them, with one side increasing by "k" for each increase in the other side.
  1. Multiply the left by k, so y = \frac{k}{\sqrt{x} }
  2. we know that y= 5, for x = 36, so sub this in the equation
  3. 5 = \frac{k}{\sqrt{36} }
  4. simplify5 = \frac{k}{6 }
  5. re-arrange for k, <u>k = 5*6 = 30</u>
  6. now we know k, we can create the real equation, y = \frac{30}{\sqrt{x} }
  7. sub in 3 as y
  8. 3 = \frac{30}{\sqrt{x} }
  9. <u>x = 100</u>

-29 is 29 bars away from 0. 100 is 100 bars away from 0.

29 + 100 = 129

So the distance between -29 and 100 is 129. The answer is D.
