3.
√250 = √(25 * 10) = √(5^2 * 10) = √(5^2) * √10
… = 5 √10
=> <em>a</em> = 5
4.
√(-300) = √(-1 * 3 * 100) = √(-1 * 3 * 10^2) = √(-1) * √3 * √(10^2) = <em>i</em> * √3 * 10
… = 10<em>i</em> √3
=> -<em>a</em> = 10 and <em>b</em> = 3 => <em>a</em> = -10 and <em>b</em> = 3
=> <em>a</em> - <em>b</em> = -10 - 3 = -13
Answer:
Step-by-step explanation:
well thats the graph 4 u
8.5 minutes per mile is equivalent to
17 minutes
----------------
2 miles
and the reciprocal of that is
2 miles
-----------
17 min
Now multiply 26.2 miles by
17 min (17 min)* (26.2 mi)
------------ , obtaining ---------------------------
2 miles 2 mi
This simplifies to (17)(26.2)/2 minutes = 222.7 minutes,
or
222.7 minutes 1 hr
-------------------- * ------------ = 3.7 hours
1 60 min
Answer:
The answer is -1 1/2
Step-by-step explanation:
This problem doesn't have that much steps.
What you do is this.
Step 1: You have 2 7/8 and 4 3/8 now turn it into a improper faction it will look like this 23/8 -35/8
Step 2: Now minus 23/8 and 35/8 23-35= -12 and the 8's stay the same now it will look like this -12/8
Step 3: Now see how many times 8 can go into -12 so -8 times 1= -8 now get from -8 to -12 that equals 4 so it will look like this -1 4/8 that can be simplify by 4 because 4x1=4 And 4x2=8 Now your answer is -1 /12
Answer:8
Step-by-step explanation:
The equation for a triangle is base times height times 1/2 so if 8 times 6 gives you 48 once you divide it by two it gives you 24
