The correct answer is D. 1/√3

Step-by-step explanation:

The ratio of the opposite side and the adjacent side to the given angle is the tangent.

According to the image below formula is:

tangent(α)=a/b

a= oppositive side: the side in front of the given angle.

b= adjacent side: the side next to the given angle.

α= the given angle.

According to the image, the value of “a” is 1 and there is √3 for “b”.

So, the correct answer is D. 1/√3

On Monday Carlos ran 1/8 of a mile.in Wednesday's he ran 5/6 of a mile.carlos ran 3/8 of a mile in Friday.which day did Carlos run the furthest

Answers

The answer is Wednesday.

because:

1/8 equals 3/24, 5/6 equals 20/24, and 3/8 equals 9/24.

3/24 < 9/24 < 20/24

and 20/24 is 5/6, which is Wednesday. 

Sergei says that 10% of a number will always be less than 20% of any other number.

Answers

Answer:

The statement is true sometimes

Step-by-step explanation:

Let

x------> a number

y-----> another number

we have that

0.10x < 0.20y ----> inequality that represent the situation

Verify

For x=100, y=200

substitute in the inequality the values of x and y

0.10(100) < 0.20(200)

10 < 40 -----> is true

For x=600, y=100

substitute in the inequality the values of x and y

0.10(600) < 0.20(100)

60 < 20 -----> is not true

Therefore

The inequality is true sometimes
That statement is only true sometimes.  If you use 500 and 10, 10% of 500 is 50, while 20% of 10 is only 2.  Clearly, 50 is larger than 2.

Rina drove for 1 hour at 45 mph and 1.5 hours at 50 mph. What was her average speed for the trip?

Answers

Answer:

Her average speed for the trip was 48 mph.

Step-by-step explanation:

Rina drove 1 hour at the speed = 45 mph

Distance covered in 1 hour = 45 miles

she drove 1.5 hours at the speed = 50 mph

Distance covered in 1.5 hour = 50 × 1.5 = 75 miles

Total distance covered by Rina = 45 + 75 = 120 miles

Total time taken by Rina = 1 + 1.5 = 2.5 hours

Average speed = Total distance / Total time

                           = 120 ÷ 2.5 = 48 mph

Her average speed for the trip was 48 mph.
1hour at 45mph , total distance = 45miles
1.5hours at 50kmph , total distance= 50 × 1.5 = 75miles

total distance tracaled = 120mls
total time = 2.5 hours

(miles)/(hour) = (120)/(2.5) = 48mph
