Answer:
-1/2
Step-by-step explanation:
-5/6 × 3/5
numerator: -5 × 3 = -15
denominator: 6 × 5= 30
-15÷30= -1/2
The answer is 5a+15b-10
5 x a is 5a. 5 x 3b is 15b and 5 x -2 is -10.
You then put them together 5a+15b-10
Answer:
398.71 ft
Step-by-step explanation:
Length of rebar = 18 inches = 1.5 ft
Elevation = 393.66 ft
Reading of backsight on Benchmark= 7.56 ft
Rod reading = 1.10 ft
<em>First step : determine height of Instrument been used</em>
= elevation + backsight on Benchmark
= 393.66 + 7.56 = 401.22 ft
<em>Elevation of top of rebar </em>
= 401.22 - 1.01 = 400.21 ft
Finally determine the elevation of the top of the pipe
= 400.21 - length of Bar
= 400.21 - 1.5 = 398.71 ft
Answer: A -22 can be a rational number as well as a integer
Step-by-step explanation:
Whole Number: A whole number is not a fraction or a decimal so a example would be: 43 or 85 or 1 or 3. Zero is not a whole number. Negative are not whole numbers
Rational number: A rational number is a number that can be expressed as a fraction or a decimal. Like 33 can be 33/1. Most numbers are rational. Zero is a rational number.
Integers: A integer is not a fraction or a decimal. its a positive or negative number. Example: 1 or -5 or 85 or -445. there is still some arguments about if zero is a integer.
Irrational numbers: A irrational number cannot be expressed as a ratio. So for example pi: 3.141592653589......(it keeps on going, we haven't even gotten to the end because its infinite).
Natural numbers: Natural numbers are positive numbers. Example: 1,6,3,4,62,3 etc. Sometimes zero is a natural number.
