Answer:
a)

b) l=19.2 units
Step-by-step explanation:
a)Let F represent the force and l represents the length of the wrench handle.
Then inverse variation relation is:

When we introduce the variation constant, we get:

From the question when F=96, l=12


The equation is

b) If a person can only exert 60 pounds of force on a wrench,then



Hence the length of the wrench must be 19.2 units
Answer:70
Step-by-step explanation:
Answer:
5/4, 2, 9/4, 3, 3/1 (the last two are the same so it could go in either order)
Step-by-step explanation:
1 1/4, 2, 2 1/4, 3, 3
The distributive properties of addition and subtraction can be used to rewrite expressions for a variety of purposes. In each case, you are distributing the outside multiplier to each number in the parentheses, so that multiplication occurs with each number before addition or subtraction occurs.
Given:
A square base pyramid whose base length is 10 in. and height of triangular surface is 4 in.
To find:
The surface area of the pyramid to the nearest whole number.
Solution:
A square base pyramid contains square base with edge 10 in. and 4 congruent triangles with base 10 in. and height 4 in.
Area of a square is



So, area of square base is 100 sq. in.
Area of a triangle is



So, area of each triangular surface is 20 sq. in.
Now, the total surface area of the pyramid is
Total area = Area of square base + Area of 4 congruent triangles.




Therefore, the area of the pyramid is 180 sq. in.
