The answer would have to be 52/87. Since it says "given", as in a geometric sense (proof), you know that the overall would have to be 87. It also adds that the students would be in the 10th grade, thus bringing us to the conclusion that 52/87 is correct. Then, simply use a calculator and put in 52/87. You're final answer, rounded to the nearest hundredth, should be 0.60.

Rule start at 5 and 1/2 add 1 1/5
Margaret [11]

Answer:

The solution is 6\frac{7}{10}.

Step-by-step explanation:

It is given that rule start at 5\frac{1}{2} add 1\frac{1}{5}.

From the given information, we get the expression

5\frac{1}{2}+1\frac{1}{5}

Simplify the complex fraction.

\frac{10+1}{2}+\frac{5+1}{5}

\frac{11}{2}+\frac{6}{5}

Taking LCM, we get

\frac{11\times 5+6\times 2}{2\times 5}

\frac{55+12}{10}

\frac{67}{10}

6\frac{7}{10}

Therefore the he solution is 6\frac{7}{10}.

Henry located 2 1/4 and 2.1 on a number line. He wrote the following related story:
Rzqust [24]

Answer:

Jerry ran a farther distance and not Henry.

Step-by-step explanation:

We are given the following information in the question:

Jerry rain 2\frac{1}{2} miles and Henry ran 2.1 miles.

Henry claimed that he ran a farther distance.

This is a wrong claim because when we compare:

2\frac{1}{2} and 2.1

2\displaystyle\frac{1}{2} = \displaystyle\frac{5}{2} = 2 + 0.5 = 2.5\\\\2.5 > 2.1

Hence, Jerry ran a farther distance and not Henry.

Henry may have made some mistake in plotting   2\frac{1}{2} and 2.1 on the number line.

(8CQ) Find the sum of the geometric series. <br> 20-10+5-5/2+...
Ivahew [28]

Answer:

b. \frac{40}{3}

Step-by-step explanation:

The given geometric series is;

20-10+5-\frac{5}{2}+...

The first term of this series is

a_1=20

The common ratio is

r=\frac{-10}{20}=-\frac{1}{2}

The sum to infinity of this series is

S_{\infty}=\frac{a_1}{1-r}

Substitute the given values to obtain;

S_{\infty}=\frac{20}{1--\frac{1}{2}}

This implies that;

S_{\infty}=\frac{20}{\frac{3}{2}}

S_{\infty}=\frac{40}{3}
