What will the value of the solution variable be after the code segment below has been run.

int solution = 80; 

int number56 = 16, number15 = 7; 

solution -= number56 * number15 ; 

What will the value of the solution variable be after the code segment below has been run.

int solution = 8; 

int number1 = 16, number10 = 3; 

solution *= number1 - number10 ;  

The formula below decribes how to convert a temperature on the Fahrenheit scale to a temperature on the Kelvin scale.

TempK = (TempF − 32) × 5/9 + 273.15

Using the variables below Write one line of code to implement the formula

// Kelvin temperature

float TempK;

// Fahrenheit temperature

float TempF = 72; 

//One line of code to calculate temperature in Kelvin

What will the value of the result variable be after the code segment below has been run.

int result ;

int number4 = 6,number11 = 9;

result = number4 + ++number11;

What will the value of the result variable be after the code segment below has been run.   

bool result ;  

int number3 = 17, number7 = 33;  

result = number3 > number7 ; 

What will the value of the solution variable be after the code segment below has been run.   

bool solution;

int number3 = 9, number7 = 29;

solution = number3 == number7;

The formula below describes Newton's second law of motion

Force = Mass x acceleration

Using the variables below Write one line of code that will calculate the acceleration of a object.

// Mass in Kg

float mass = 50.3;

// Froce in N

int force = 720; 

//acceleration

float accel;

//One line of code to calculate the acceleration of a object
