1.Explain why wrenches are useful for turning tight bolts 2.Explain how a wheelbarrow is useful for carrying heavy loads (they can be given help by telling them that the wheel is where the pivot is and their hands are further away than the load so have a larger force.

What type of question is this lol.

A long-handled wrench makes it easier to unscrew tight bolts. This is because we increase the torque by moving the applied force further from the turning point. Note, it is only the perpendicular component of the force acting on the lever that produces torque.

The pivot is the wheel's axle. Here, the output force is greater than the input force. Thus, a wheelbarrow enables you to lift much heavier loads than you could with your body alone.

Coupon 1

Step-by-step explanation:

Purchase list :

1/2 lb cheese

3 lbs sliced ham

2 loaves of bread

4 bags of potato chips

1 container of salsa.

Cost of 1 lb cheese = $1.99

So, cost of 1/2 lb =

                            =

Cost of 1 lb sliced Ham = $3.29

So, cost of 3 lb Sliced Ham =

                                             =

Cost of 1 loaf of bread = $ 1.59

So, cost of 2 loaves of bread =

                                                =

Cost of 2 bags of potato chips = $ 3

So, cost of 4 bags = $3+$3  = $6

Cost of 1 container of salsa = $1.39

So, total cost of purchase before sales tax = =

Now The food sales tax is 3%.

So, 3% of total =

                        =

                        =

Thus total cost including sales tax =

                                                        = $22.036

Coupon 1: $4.00 off if your purchase totals more than $15.00

Since total cost is more than $15

So, $4 is off on total cost

So, total cost after coupon is applied = $22.036-$4 =$18.036

Coupon 2:  10% off if the total is more than $20.00.

So, 10% of total cost =

                                  =

                                  =

So, total cost after getting 10 % off =

                                                          =19.8324

So, total cost after coupon 2 is applied = $19.8324

Hence coupon 1 will save the most money .
