Answer:

580

Step-by-step explanation:

Let's translate this word for word.

87 is 15% of what number

87 = 15% times x

87=.15 times x

87=.15 \cdot x

Divide both sides by .15

\frac{87}{.15}=\frac{.15x}{.15}

Cancel out the common factor of .15 on the right; that is .15/.15=1.

580=x

580 is the number

Answer:

580

Step-by-step explanation:

Alright. Translate that into math, and you get:

87=15/100x

multiply both sides by x

8700/15=x

x=8700/15

x=580

Check:

580*15/100

58*15/10

870/10

87

BINGO!

The Lakewood Wildcats won 5 out of their first seven games in this year. There are 28 games in the season. About how many games
allochka39001 [22]

Answer:

The total number of matches expected to be won by Lakewood Wildcats in this season  is 20.

Step-by-step explanation:

The number of games played by Lakewood Wildcats = 7

Number of matches won by Lakewood = 5

or, the ratio of Won : Played = 5: 7

Total numbers of games in the season = 28

Let the Lakewood Wildcats win m number of games.

Here, ratio of Won Matches : Played Matches = m : 28

Now, by RATIO OF PROPORTIONALITY:

\frac{5}{7}   = \frac{m}{28}

⇒m = \frac{28 \times 5}{7}  = 20

or, m = 20

Hence, the total number of matches expected to be won by Lakewood Wildcats out of total 28 matches is 20.

Determine whether the improper integral converges or diverges, and find the value of each that converges.
Temka [501]

Answer:

It diverges.

Step-by-step explanation:

We are given the inetegral:  \int\limits^{\infty}_2 \frac{1}{x} (\ln x)^2 dx

\int\limits^{\infty}_2 \frac{1}{x} (\ln x)^2 dx=\int\limits^{\infty}_2 (\ln x)^2 d(\ln x)=\\\\=\lim_{t \to \infty} \int\limits^t_2 (\ln x)^2d(\ln x)=\lim_{t \to \infty} \frac{(\ln t)^3}{3} |^t_2=\infty-\frac{(\ln 2)^3}{3} =\infty

So it is divergent.
