(General math) a. A balance has the following weights: 100 lb, 50 lb, 10 lb, 5 lb, and 1 lb. The number of 100 lb and 50 lb weights required to weigh an object weighing WEIGHT pounds can be calculated by using the following C++ statements:
Using these statements as a starting point, write a C++
b. Without compiling or running your program, manually check the effect of each statement in the program and determine what’s stored in each variable as each statement is encountered.

- (Practice) Determine the values of the following integer expressions: a.3+46f.202/( 6+3)b.34/6+6g.( 202)/6+3c.23/128/4h.( 202)/( 6+3)d.10( 1+73)i.5020e.202/6+3j.( 10+3)4arrow_forward(General math) The volume of oil stored in an underground 200-foot deep cylindrical tank is determined by measuring the distance from the top of the tank to the surface of the oil. Knowing this distance and the radius of the tank, the volume of oil in the tank can be determined by using this formula: volume=radius2(200distance) Using this information, write, compile, and run a C++ program that accepts the radius and distance measurements, calculates the volume of oil in the tank, and displays the two input values and the calculated volume. Verify the results of your program by doing a hand calculation using the following test data: radius=10feetanddistance=12feet.arrow_forward(Physics) a. The weight of an object on Earth is a measurement of the downward force onth e object caused by Earth’s gravity. The formula for this force is determined by using Newton’s Second Law: F=MAeFistheobjectsweight.Mistheobjectsmass.AeistheaccelerationcausedbyEarthsgravity( 32.2ft/se c 2 =9.82m/ s 2 ). Given this information, design, write, compile, and run a C++ program to calculate the weight in lbf of a person having a mass of 4 lbm. Verify the result produced by your program with a hand calculation. b. After verifying that your program is working correctly, use it to determine the weight, on Earth, of a person having a mass of 3.2 lbm.arrow_forward
- (Practice) State whether the following variable names are valid. If they are invalid, state the reason. prod_a c1234 abcd _c3 12345 newamp watts $total new$al a1b2c3d4 9ab6 sum.of average volts1 finvoltarrow_forward(General math) a. Design, write, compile, and run a C++ program to calculate the volume of a sphere with a radius, r, of 2 in. The volume is given by this formula: Volume=4r33 b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the volume of a cube with a radius of 1.67 in.arrow_forward(Physics) a. Design, write, compile, and run a C++ program to calculate the elapsed time it takes to make a 183.67-mile trip. This is the formula for computing elapsed time: elapsedtime=totaldistance/averagespeed The average speed during the trip is 58 mph. b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the elapsed time it takes to make a 372-mile trip at an average speed of 67 mph.arrow_forward
- (Practice) Determine the value of the following floating-point expressions: a.3.0+4.06.0b.3.04.0/6.0+6.0c.2.03.0/12.08.0/4.0 d.10.0( 1.0+7.03.0)e.20.02.0/6.0+3.0f.20.02.0/( 6.0+3.0)g.( 20.02.0)/6.0+3.0h.( 20.02.0)/( 6.0+3.0)arrow_forward(General math) a. Write a C++ program to calculate and display the value of the slope of the line connecting two points with the coordinates (3,7) and (8,12). Use the fact that the slope between two points with the coordinates (x1,y1)and(x2,y2)is(y2y1)/(x2x1). b. How do you know the result your program produced is correct? c. After verifying the output your program produces, modify it to determine the slope of the line connecting the points (2,10) and (12,6). d. What do you think will happen if you use the points (2,3) and (2,4), which results in a division by zero? How do you think this situation can be handled? e. If your program doesn’t already do so, change its output to this: The value of the slope is xxx.xx The xxx.xx denotes placing the calculated value in a field wide enough for three places to the left of the decimal point and two places to the right of it.arrow_forward(General math) a. Design, write, compile, and run a C++ program that calculates and displays the area of a triangle, such as the one in Figure 2.18, with a base of 1 in and a height of 1.5 in. The area is given by this formula: Area=12(base)(height) b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the area of a two-dimensional triangle with a base of 3.5 in and a height of 1.45 in.arrow_forward
