What is the sum of each pair of binary integers?
Natali5045456 [20]
Add digit by digit, from the right, just like any number, except that if it adds to 2, then put a zero and carry one (instead of carrying when it adds to 10 or more).

Example:  < means carry, decimal equivalent for checking
1011+1111

     1     0     1     1         (8+2+1=11)
+   1     1     1     1         (8+4+2+1=15)
---<---<----<----<----
1   1     0     1     0         (16+8+2=26)

Proceeding similarly,
a. 10101111+11011011 = 110001010  (394)
b. 10010111+11111111  = 110010110  (406)
c.  01110101+10101100 = 10010001  (289)

How to find a slope
exis [7]

Answer:

Step-by-step explanation:

y₂₋y₁ / x₂-x₁   if you have two points you can plug them in and find the slope using this.

If it is on a graph you can look at two points and count the rise over run, for example if one point is (0, 0) and another is (2, 3) then from the first point it goes up 2 and over 3, so the slope would be 2/3

a circular racecar track has a radius ig 1.6 miles.about how many times must a car drive around the race track to drive 15 miles
madam [21]
He has to drive around the track about 1.5 times.

We first find the circumference:

C = 2πr = 2(3.14)(1.6) = 10.048

We now divide 15 by this:
15/10.048 ≈ 1.5
