Answer: 14.4 h

The speed is : v=\frac{d}{t} =\frac{252}{13} =19.46 miles/h\\

The time it takes to travel 279 miles :

t'=\frac{d}{v} =\frac{279}{19.46} =14.4 hours

ben is three times as old as carl now. In two years time, ben will be twice as old as carl. How old is carl now?​
ss7ja [257]

Let Carl's age be c and Ben's age be 3c.

Equation:

3c = 2c + 2

=> 3c - 2c = 2

=> c = 2

So, Carl is 2 years old.

Int var1 = 0b0001; int var2 = 0b1111; int results1 = var1 & var2; int results2 = var1 | var2; int results3 = var1 ^ var2; in
Afina-wow [57]
<span>Int var1 = 0b0001;
int var2 = 0b1111;
int results1 = var1 & var2;
int results2 = var1 | var2;
int results3 = var1 ^ var2;
int printit = results1 + results2 + results3;
 
what are the values for results1, results2, results3 and printit after executing the code?
notes:
1. faster responses will be obtained if your code is presented line by line (in a file) before posting.
2. please specify language, many languages use the same syntax but could have differences in interpretation
-------------------------------------------------------------------------------

Assuming Java as the language.  C is similar.
</span><span><span>& bitwise AND &
^ </span><span>bitwise exclusive OR
</span><span>| bitwise inclusive OR

So 
results1=var1&var2=0b0001&0b1111=0b0001
results2=var1|var2=0b0001&0b1111=0b1111
results3=var1^var2=0b0001&0b1111=0b1110
printit=results1+results2+results3=0b0001+0b1111+0b1110
=0b10000+0b1110
=0b11110   

Note: by default, int has 4 signed bytes, ranging from decimal -2147483648 to +2147483647

A car uses 8 gallons of gasoline to travel 290 miles.Juanita wants to take a trip that is 400 miles. What equation will she need
olchik [2.2K]

Answer:

To find this answer, you would need to find how many miles 1 gallon of gas will take them. To find this, you would do 290÷8=36.25. So with this information, you will be able to find out how much gas it would take to travel 400 miles. You would do 400÷36.25=11.03. 11.03 would be how many gallons of gas is used to travel 400 miles. Hope this helps! :)
