Answer:5
Step-by-step explanation:
Answer: The angles are 67.5°, 22.5° and 90°.
Step-by-step explanation:
It should be noted that a straight angle is always equal to 180°.
The straight angle is split in the ratio 3:1:4.
The measure of each angle will be:
a. = 3/(3+1+4) × 180°
= 3/8 × 180°
= 67.5°
b. 1/8 × 180° = 22.5°
c. 4/8 × 180° = 90°
The angles are 67.5°, 22.5° and 90°.
Answer:
it would be
The dependent variable is distance, the equation is y = 35x, and the dragonfly will travel 840 miles
Step-by-step explanation:
By the graph it can be seen that the distance a dragonfly can travel is dependent on the certain number of hours.
∴ Dependent variable : Distance (on y axis)
The equation of straight line is given by :-
, here m is the slope of the line and c is the initial value of y at x=0.
From the given graph, the slope of the given line passing from (0,0) and (2,70) will be :-
Also, the value of y = 0 at x=0.
∴ The equation of the given line :
At x=24,
∴ The dragonfly will travel 840 miles in 24 hours.
