Answer:
x = 10.9
Step-by-step explanation:
Since the triangle is right, use the tangent ratio to find the value of x
tan36° = = =
Multiply both sides by 15
15 × tan36° = x
⇒ x = 10.9 ( to nearest tenth )
So we are assuming that the three shirts have equal price. Let the price of one shirt be a.
In store A:
the cost is (a+a+a) -(25/100)a=3a-0.25a=2.75a
In store B:
the cost is : a+a+50/100 a =a+a+0.5a=2.5a
In store C:
the cost is
[a-(10/100)a]+[a-(10/100)a]+[a-(10/100)a]=[a-0.1a]+[a-0.1a]+[a-0.1a]
=0.9a+0.9a+0.9a= 2.7a
thus the cost of buying the shirts from stores A, B and C is:
2.75a, 2.5 a and 2.7 a respectively.
the best deal, is buying from store B, where the cost is the lowest: 2.5a.
Answer: store B
The cross section is A. Hexagon, a 6-sided figure.
Answer:
Noah mixes 4 scoops of powder with 6 cups of water.
Means Noah ratio will be or 0.67
Andre mixes 5 scoops of powder with 8 cups of water
Means Andre ratio will be or 0.62
As, or 0.66 > 0.62
We can say that content of orange powder will be more in Noah mixture than in Andre's Mixture.
Hence, Noah's mixture will taste more like orange, than Andre's mixture.
