False it could only occur 1/4 since there is only 4 colors
Well 18/5= 3.6
is this what you need to know?
Answer:
A) x = 11 tan 49°
B) 12.7 inches
C) 14.7 inches
Step-by-step explanation:
(refer to attached for reference)
Let the length of the vertical side of the triangular sail be x
recall that for right angle triangle, the following trigonometric relation applies:
tan θ = length of opposite side / length of adjacent side
in our case,
θ = 49°
length of adjacent side = 11 inches
length of opposite side = length of vertical edge of sail = x (which we defined above)
hence we can assemble our formula
tan 49° = x / 11 (rearranging)
x = 11 tan 49° (Answer for A)
Using a calculator to solve this gives
x = 12.65 inches
x = 12.7 inches (to nearest tenth) (Answer for B)
The height of the mast is merely the height of the sail plus the 2" length of mast extending below the sail.
Mast height = 12.7" + 2" = 14.7" (Answer for C)
Answer:
D
Step-by-step explanation:
The diagramatic representation of the life cycle of a darkling beetle is shown in the attached file below.
The metamorphosis of the darkling bettle takes four stages:
egg → larva → pupa→ adult
After laying the eggs by an adult darkling bettle, the eggs are encased in a fluid-like covering to prevent it from damage as a result of environmental factors. The egg metamorphosize into the larva stage; a period of feeding and growth. They then in turn proceed into the pupa stage where they are being enclosed in a cocoon. In the cocoon, they undergo modifications and become sexually matured before they enters into adulthood.
Thus, the stage that represent the change fromm larva to adult is the pupa stage and it is shown in the diagram as option D
Answer:
17 in.
Step-by-step explanation:
There are two same angles shown, so two sides are equal. We can form an equation x+4=4x+1. Solution is x=1, then both unknown sides are 5 in. long. Given all side lengths we add them 7+5+5+15 getting the perimeter.
