Answer:
95.49 g
Step-by-step explanation:
D = m/v
Looking for mass so isolate m to form equation format
D × V = m
Plug in numbers
.7892g/mL × 121.0 mL = 95.4932 g
Only g and not g/mL because the mL cancels each other out. It's easier to see if you rewrite it on paper.
Round to sig figs
Both original numbers hold 4 sig figs
95.49 g
Answer: 110 square cm
=======================================================
Explanation:
All sides of a regular polygon are the same length. So the bottom side is also 8 cm.
Draw lines from the center to each vertex of the pentagon. Five triangles form. Each triangle has a base of 8 and a height of 5.5 (since all five triangles are congruent)
area of one triangle = 0.5*base*height = 0.5*8*5.5 = 22
area of five triangles = 5*(area of one triangle) = 5*22 = 110

Answer:
y=-2/1x+5 or y=-2x+5
Step-by-step explanation:
well, you know that the equation form for this is y=mx+b, and for this the m=the slope because the lines decent is ongoing forever so it is next to the x. to count the slope, you take it from one intersection which in this case would be 5 and take it to the next which is at (1,3) and the slope would be down(or negative) 2 over(right) 1 and since the way you label it is y/x and with a normal fraction you would disregard the 1 as useless and you would take the 2 as a whole number. now for the b, B=where the line intersects a number on the Y-axis, not the x-axis, usually never is the Y-axis, which in this case would be 5, its as simple as that. have a good day ;)
