Answer:

[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1

(5/60 + 3/60)x = 1

(8/60)x = 1 we can reduce 8/60 by dividing out a 4

(2/15)x = 1 x both sides by 15/2

x = 15/2

x = 7 1/2 or 7.5 hours

Answer:

Option (2)

Step-by-step explanation:

We have to arrange the given numbers in the order from least to greatest.

Numbers are $\sqrt{64},8\frac{1}{7},8.1414..., \frac{15}{2}$

1). $\sqrt{64}=8$

2). $8\frac{1}{7}=\frac{57}{7}=8.143$

3). 8.1414....

4). $\frac{15}{2}=7.5$

Therefore, increasing order of the numbers will be,

$8.143>8.1414>8>7.5$

$8\frac{1}{7}>8.1414...>8>7.5$

Option (2) will be the correct option.

brilliants [131]

Answer:

Length SD is greater than length DM.

Step-by-step explanation:

We know that the measure of the opposite angle and a side are related, so by determining which angle is bigger, we can discover which side is longer.

Angle SUD is greater than angle MUD. Angle SUD is the opposite angle to SD, and angle MUD is the opposite angle to DM. Therefore, SD is greater than DM.
