Write each as a fraction or mixed number in lowest terms<br> 6.05 <br> 12.346<br> 7.5

AVprozaik [17]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the decimal number

$6.05$

Rewrite as

$=6+0.05$

$=6+\frac{5}{100}$ ∵ 0.05 = 5/100

$=6+\frac{1}{20}$

$=\:\frac{121}{20}$

$=6\frac{1}{20}$

Given the decimal number

12.346

Rewrite as

$=12+0.346$

$=12+\frac{173}{500}$ ∵ 0.346 = 346/1000 = 173/500

$=12\frac{173}{500}$

Given the decimal number

7.5

Rewrite as

$=7+0.5$

$=7+\frac{1}{2}$ ∵ 0.5 = 1/2

$=7\frac{1}{2}$

A football stadium holds 17,700 seats. The lower level has 300 seats less than 4 times the number of seats in the upper level. T

grigory [225]

Answer:

6x + 200 = 17,000

Step-by-step explanation:

Lower level = 4x - 300

Mid level = 2x + 500

Combine the two equations to find the number of seats in the upper level

(2x + 500) × (4x - 300) = 17,000

Combine like terms

4x × 2x + 500 - 300 = 17,000

<em>6x + 200 = 17,000</em>

Evaluate S5 for 300 + 150 + 75 + … and select the correct answer below. 18.75 93.75 581.25 145.3125

Savatey [412]

we have that

$300 + 150 + 75 +...$

Let

$a1=300\\ a2=150\\ a3=75$

we know that

$\frac{a2}{a1} =\frac{150}{300} \\\\ \frac{a2}{a1}=0.5 \\ \\ a2=a1*0.50$

$\frac{a3}{a2} =\frac{75}{150} \\\\ \frac{a3}{a2}=0.5 \\ \\ a3=a2*0.50$

so

$a(n+1)=an*0.50$

Is a geometric sequence

Find the value of $a4$

$a(4)=a3*0.50$

$a(4)=75*0.50$

$a(4)=37.5$

Find the value of $a5$

$a(5)=a4*0.50$

$a(5)=37.5*0.50$

$a(5)=18.75$

Find $S5$

$S5=a1+a2+a3+a4+a5\\ S5=300+150+75+37.5+18.75\\ S5=581.25$

therefore

the answer is

$581.25$

Alternative Method

Applying the formula

$S_n=\frac{a_1 (1-r^n)}{1-r} \\\\a_1=300 \\ r=\frac{1}{2}\\\\ S_5=\frac{300(1-(\frac{1}{2})^5)}{1-\frac{1}{2}}\\\\=\frac{300(1-\frac{1}{32})}{\frac{1}{2}}\\\\=\frac{300 \times \frac{31}{32}}{\frac{1}{2}}\\\\=\frac{75 \times \frac{31}{8}}{\frac{1}{2}}\\\\=\frac{\frac{2325}{8}}{\frac{1}{2}}\\\\=\frac{2325}{8} \times 2\\\\=\frac{2325}{4}\\\\=581 \frac{1}{4}\\\\=581.25$

therefore

the answer is

$581.25$
