Answer:
5 word problems(4points each) & 10 open (3 points each)
Step-by-step explanation:
O= open response
W= word problems
W+O =15
4W + 3O = 50
multiply the first by -3 to eliminate O
-3W -3O = -45
4W + 3O = 50
AD BOTH
W = 5 ( 5 questions word problems)
O= 10 ( 10 questions open response)
5x4 = 20
10x3 = 30
20 + 30 = 50 points
It must be 21.3 feet.
The sides of the triangle given to us are the side opposite the angle to the ground, 20, and the missing side is the hypotenuse.
opposite/hypotenuse is the ratio for sine:
sin 70 = 20/x
Multiply by x:
x sin 70 = 20
Divide both sides by sin 70:
(x sin 70)/(sin 70) = 20/(sin 70)
x = 21.283 ≈ 21.3
Based on the distance of Planet X from Earth and the distance of Planet Y, Planet X is 5 ³/₅ light-years farther away.
<h3>How much farther is Planet X from Earth?</h3>
To find how out how much farther planet X is from Planet Earth than Planet Y, subtract the distances:
Solving gives:
= 8 ¹/₅ - 2 ³/₅
= 41/5 - 13 / 5
= 28/5
= 5 ³/₅ light-years
