Answer: The average number of miles she would have to ride each day to meet her goal = 3.2 miles.

Step-by-step explanation:

Given: Elizabeth wants to ride her bicycle 28.6 miles this week.

She already ridden 19 miles.

Number of days she will ride more =3

Let m = average number of miles ridden in a day.

Then,

Total distance = initial distance + (m) (Number of days)

i.e. 28.6 = 19+3m   (Required equation)

Subtract 19 from both sides , we get

9.6=3m\\\\\Rightarrow\ m=\dfrac{9.6}{3}\\\\\Rightarrow\ m=3.2\ miles

Hence, the average number of miles she would have to ride each day to meet her goal = 3.2 miles.

From exterior point L of circle O, tangent segments LP and LQ are drawn such that the measure of angle PLQ is 60 degrees. If a r
IrinaK [193]

Wow !  There's so much extra mush here that the likelihood of being
distracted and led astray is almost unavoidable.

The circle ' O '  is roughly 98.17% (π/3.2) useless to us.  The only reason
we need it at all is in order to recall that the tangent to a circle is
perpendicular to the radius drawn to the tangent point.  And now
we can discard Circle - ' O ' .
Just keep the point at its center, and call it point - O .

-- The segments LP, LQ, and LO, along with the radii OP and OQ, form
two right triangles, reposing romantically hypotenuse-to-hypotenuse. 
The length of segment LO ... their common hypotenuse ... is the answer
to the question.

-- Angle PLQ is 60 degrees.  The common hypotenuse is its bisector.
So the acute angle of each triangle at point ' L ' is 30 degrees, and the
acute angle of each triangle at point ' O ' is 60 degrees.

-- The leg of each triangle opposite the 30-degree angle is a radius
of the discarded circle, and measures 6 .

-- In every 30-60 right triangle, the length of the side opposite the hypotenuse
is  one-half the length of the hypotenuse.

-- So the length of the hypotenuse (segment LO) is  <em>12 </em>.

a poker hand of 5 cards is dealt from a standard 52 card deck. a full house consists of exactly 3 of one kind of card and a pair
sergiy2304 [10]
The triple card can be any one of 13 values (ace through king). For each of those, the double card can be any one of the remaining 12 values. So concerning only the face values of the cards, there are (13 x 12) = 156 different full hice. If you include attention to the suits, then there a lot more.

Gennadij [26K]

Answer:

\boxed{\text{It doubles}}

Step-by-step explanation:

f(x)=4(2)^{x}

Let's create a table of the values.

\begin{array}{lr}\mathbf{x} & \mathbf{f(x)} \\0 & 4 \\1 & 8 \\2 & 16 \\3 & 32 \\4 & 64 \\5 & 128 \\\end{array}\\\text{The number of people sharing the video $\boxed{\textbf{doubles}}$ every hour}
