According to the same report, the 28.5 million passengers in 2018 represented a 6.7% increase in cruise passengers since 2017. h

Alisiya [41]

The number of cruise passengers must there have been in 2017 is 26.7 million.

<h3>What is percentage?</h3>

The term "percentage" comes from the Latin phrase "per centum," meaning "by the hundred." Percentages represent fractions with a denominator of 100. In other terms, it is the relationship between portion and whole in which the value of the whole is always assumed to be 100.

Now according to the question;

Let x represent the total number for cruise passengers during 2017.

In 2018, a 6.7% rise in x results in 28.5 million cruise passengers.

So, 106.7 % of x = 28.5

$\begin{aligned}&\frac{106.7}{100} * x=28.5 \\&\frac{106.7 x}{100}=28.5\end{aligned}$

Multiplying both sides by 100;

$\begin{aligned}&\frac{106.7 x}{100} * 100=28.5 * 100 \\&106.7 x=2850\end{aligned}$

Dividing both sides by 106.7;

$\frac{106.7 x}{106.7}=\frac{2850}{106.7}$

x = 26.7

Therefore, the number of cruise passengers in 2017 must have ranged from 26.7 million.

Gillian read 3135 words in 19 minutes. Let w represent the words read each minute. If Gillian read the same number of words each

sweet [91]

Answer:

she read 165 words per minute

Step-by-step explanation:

if you tell us that Gillian read 3135 words in 19 minutes we can represent it as follows

19 m = 3135w

so now we have to find out how much I read in 1 minute, for this we have to divide both parts of equality by 19

19m = 3135w

19m/19 = 3135w/19

1m = 165w

she read 165 words per minute

George’s parents are saving for his college fund. they put $5,000 into an interest bearing account with a compound interest rate

sergey [27]

so hmmm is compound interest, now, we'll be assuming the compounding period is per year, or annually, so it happens once per year.

$~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$5000\\ r=rate\to 5.5\%\to \frac{5.5}{100}\dotfill &0.055\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{annually, thus once} \end{array}\dotfill &1\\ t=years\dotfill &15 \end{cases} \\\\\\ A=5000\left(1+\frac{0.055}{1}\right)^{1\cdot 15}\implies A=5000(1.055)^{15}$

Three tennis balls are stored in a cylindrical can with

adoni [48]

Answer:

87.9 in³

Step-by-step explanation:

Volume of the can

V = πr²h [volume of a cylinder]
V = 3.14 x 2 x 2 x 8
V = 3.14 x 32
V = 100.48 in³

Volume of 3 tennis balls

V = 4/3πr³ [volume of one sphere]
V = 3 x 4/3 x 3.14 x 1³ [for 3 tennis balls]
V = 4 x 3.14
V = 12.56 in³

Remaining space

Volume of can - Volume occupied by 3 tennis balls
100.48 - 12.56
87.92 in³ ⇒ 87.9 in³
