The answer is 1.55

Explanation:

The he first step to find the range is to make all the values either fractions or decimal/integer numbers. Below I show the process to make all the numbers decimals/integers

Height in miles

2.75: This number is decimal because of this it does not have to be modified

2 \frac{2}{3}: This number includes a rational number and a fraction to make this just one number write the first number as a fraction, multiply, and then divide the top number by the low number (denominator).

\frac{2}{1} ×\frac{2}{3} = \frac{4}{3} = 1.333

\frac{49}{20} : This number is a fraction to simplify it divide the nominator by the denominator:

\frac{49}{20}= 2.45

2 \frac{3}{5}: Write the integer as a fraction and then simplify

\frac{2}{1} ×\frac{3}{5} = \frac{6}{5} = 1.2

Now, from these values, the higher one is 2.75 and the lowest is 1.2, to find the range find the difference between these two numbers 2.75 - 1.2 = 1.55

If two dice are rolled one time, find the probability of getting: a sum grater than 10\
lilavasa [31]
If two dices are rolled once, you would have a total number of 6*6=36 possibilities.
To get a sum greater than 10:
A) one of your dices could be showing a 5, the other a 6. That’s two possibilities. Dice A being the 5 or dice B being the 5.
B) both of your dices could be showing 6s.
That’s one possibility.
So your overall possibility to get a sum greater than 10 is (1+2)/36 3/36=1/12

To measure the height of a tree, a surveyor walked a short distance from the tree and found the angle of elevation was 43.9°, th
padilas [110]

Answer:

The height of the tree is H = 77.06 m

Step-by-step explanation:

From Δ ABC

AB = height of the tree

\tan 43.9 = \frac{AB}{BC}

\tan 43.9 = \frac{h}{x}

h = 0.9623 x ------- (1)

From Δ ABD

\tan 37.6 = \frac{h}{20+ x}

h = 0.77 (x + 20) ----- (2)

Equating Equation  1 & 2 we get

0.9623 x =  0.77 (x + 20)

0.9623 x = 0.77 x + 15.4

x (0.1923) = 15.4

x = 80.08 m

Thus the height of the tree is given by

H = 0.9623 x

H = 0.9623 × 80.08

H = 77.06 m

Therefore the height of the tree is H = 77.06 m
