<span>So the given numbers are:
=> One year, the price of wheat is 8.87 dollars
=> the next year, the price of wheat is 9.60 dollars.
We were asked to round each prices of bushels of wheat to its nearest tenths.

Sunny_sXe [5.5K]
28 students....ratio of boys to girls is 2 to 5...added = 7

2/7(28) = 56/7 = 8 boys
5/7(28) = 140/7 = 20 girls
so right now, there is 8 boys and 20 girls (8/20 = 2/5)

so lets add 2 boys...making it 30 students
10 boys and 20 girls = 10/20 = 1/2 or 1 to 2

answer is : u have to add 2 boys to get a ratio of boys to girls = to 1:2

Answer:

31 feet

Step-by-step explanation:

Find x by using the tangent function. Tangent is the opposite over the adjacent.

tan 52 = \frac{40}{x}\\x(tan52) = 40\\x=\frac{40}{tan 52} \\x= 31.25

The distance rounded was 31 feet.

Help please
Kay [80]

so the jet ski costs 2925, she'll get a loan for 48 months, well, keeping in mind that there are 12 months in a year, 48 months is really 48/12 years, namely 4 years.


\bf ~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad  \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\to& \$2925\\ r=rate\to 6.5\%\to \frac{6.5}{100}\to &0.065\\ t=years\to &4 \end{cases} \\\\\\ I=(2925)(0.065)(4)\implies I=760.5
