Check the picture below.
bear in mind that, the "bases" are the two parallel sides, and the height is the distance between them.

so, the area for this trapezoid is then
Direct variations can be set up as proportions
5/75 = 8/x....5 hrs to 75 dollars = 8 hrs to x dollars
now we cross multiply
(5)(x) = (75)(8)
5x = 600
x = 600/5
x = 120 <== so he makes $120 for working 8 hrs
another way...
75/5 = 15..so he makes 15 per hr
15 * 8 = 120
Add the common like terms but first seperate them and the pair them
Answer:
25/32 chapter per hour
Step-by-step explanation:
(5/8)/(4/5)=x/1
cross product
4/5*x=(5/8)(1)
4/5x=5/8
x=(5/8)/(4/5)
x=(5/8)(5/4)
x=25/32
Answer:
x = 3
m<PAW = 1
Step-by-step explanation:
☆They are supplementary angles.
☆Supplementary angles equal 180 degrees.
☆Plug in for m<AEZ
☆m<PAW is corresponding to m<AEZ
☆Corresponding angles are congruent.
☆m<PAW equals 1.
