If 2^y = 3, then:

(log to the base 2 of) 2^y = (log to the base 2 of) 3
                  or
                                      y = log to the base 2 of 3

Note that y turns out to be a constant here.
We need to identify the graph that depicts (log to the base 2) of x, and once we have that, draw a vertical line thru x = 3 to estimate y.

Only the 3rd graph qualifies here.  Note that all basic log graphs have an x-intercept of (1,0), as the 3rd graph does.

If we draw on the 3rd graph a vertical line thru x=3, we see that this vert. line intersects the curve at roughly y=1.5.

Michael has a ball that has a radius of 3 inches and Patrick has a ball that has a radius
Diano4ka-milaya [45]

Answer:

27 times bigger

Step-by-step explanation:

V(sphere) = 4/3πr³

Michael:  4/3π3³ = 4/3×27π or 36π

Patrick:  4/3πr³ = 4/3πx9³ or 4/3x729π or 972π

36π to 972π is 1 : 27

Una botella pesa 1090kg cuando esta llena y 250g cuando esta vacía. ¿Cuanta masa de aceite contiene la botella?
Hitman42 [59]

Respuesta:

1089,75 kg

Explicación paso a paso:

Dado que :

Masa de embotellado lleno = 1090 kg

Masa de la botella vacía = 250 g

Masa de aceite que contiene la botella:

Expresando la masa de la botella cuando se llena en gramos:

1000 g = 1 kg

1090 kg = (1090 * 1000) = 1090000 g

La masa de aceite que contiene la botella es así:

Masa de la botella cuando está llena - masa de la botella cuando está vacía

1090000 g - 250 g = 1089750 g

Por tanto, la masa de aceite es 1089750 g

O 1089750/1000 = 1089,75 kg

There are two spinners. The first spinner has three equal sectors labeled 1, 2 and 3. The second spinner has four equal sectors
sladkih [1.3K]
Given that the first spinner has three equal sectors labelled 1, 2 and 3; and the second spinner has equal sectors labelled 3, 4, 5 and 6.

The number of possible outcomes that do not show a 1 on the first spinner is 2 (i.e. the first spinner shows 2 or 3).

The number of possible outcomes that the second spinner show the number 4 is 1 (i.e. the second spinner shows 4)

In probability, the word 'and' goes with multiplication.

Therefore, <span>the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner</span> is given by 2 x 1 = 2 possible outcomes.

i.e. the first spinner shows the number 2 and the second spinner shows the number 4 or the first spinner shows the number 3 and the second spinner shows the number 4.
