-1/8 - 55/8 = -56/8 = -7
3.4
(-4x7)/10 = -28/10 = -14/5
3.5
-19/2 ÷ 38/7 <=> -19/2 x 7/38 and simplify = -7/4
..........solve it like an equation
Answer: 
Step-by-step explanation:
1. A number written in scientific notation has the following form:

Where is
is a number between 1 and 10 but not including 10, and b is an integer.
2. The negative exponent indicates the number of places the decimal point must be moved to the left to obtain the number as a decimal number.
3. Keeping this on mind, you can know that: if the exponent of a number written in scientific notation indicates that the decimal point must be moved 5 places to the left and another number written in scientific notation indicates that the decimal point must be moved 2 places to the left, then the first number is smaller than the second one.
4. Therefore, you can arrange the numbers given in the problem as following:

Answer:
sin B= 0.096288
B = 5.525°
Step-by-step explanation:
Consider ΔABC as shown in figure attached
From figure:
a = 1 m
b = 3.54 m
sin A = 0.0272
sin B = ?
Using the sine rule for non-right-angle triangle

The number of times I would expect to roll a number that is not a 5 is 300 times.
<h3>What is the number of times a 5 won't be rolled?</h3>
A standard die has 6 faces. There are 5 numbers that are not 5 on a standard die. They are 1, 2, 3, 4, 6.
The number of times a 5 won't be rolled = (5/6) x 360
5 x 60 = 300 times
