In a local city, the temperature at noon is -3C The temperature is expected to decrease by 2.5C each hour until the temperature

LiRa [457]

Writing the equation that governs this situation:

-3C - (2.5C/hr)x = -18C

Simplifying, -3 - 2.5x = -18, or 3 + 2.5x = 18

Combining like terms: 2.5x = 18-3 = 15

Then x = 15/2.5 = 6. The temp. will reach -18C after 6 hours.

Four plumbers estimated the length of the radius of a cylindrical pipe. The estimates made by the plumbers are listed. Which lis

suter [353]

Answer:

$\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}$

Step-by-step explanation:

To get the order of the lengths in the order from greatest to least we will make the denominator of the given fractions common and then compare the numerators.

$\frac{3}{25}, \frac{\sqrt{3}}{11}, \frac{9}{100},\frac{\pi }{24}$

LCM of the denominators,

2 | 25 11 100 24

2 | 25 11 50 12

5 | 25 11 25 6

5 | 5 11 5 6

1 11 1 6

LCM = 2×2×5×5×6×11 = 6600

$\frac{3}{25}=\frac{3}{25}\times \frac{264}{264}$

$=\frac{792}{6600}$

$\frac{\sqrt{3}}{11}=\frac{\sqrt{3} }{11}\times \frac{600}{600}$

$=\frac{600\sqrt{3}}{6600}=\frac{1039}{6600}$

$\frac{9}{100}=\frac{9}{100}\times \frac{66}{66}$

$=\frac{594}{6600}$

$\frac{\pi }{24}=\frac{\pi }{24}\times \frac{275}{275}$

$=\frac{275\pi }{6600}$

$=\frac{864}{6600}$

Now we can arrange these fractions in the order of greatest to least.

$\frac{1039}{6600}>\frac{864}{6600}>\frac{792}{6600}>\frac{594}{6600}$

$\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}$
