In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If
Vesna [10]

Answer:

Cranberry:Apple:Orange = 7:5:8

Step-by-step explanation:

Given

Apple = 1/4

Orange = 2/5

Required

Determine the ratio of Cranberry to Apple to Orange

First, we calculate the fraction of Cranberry using:

Cranberry + Apple + Orange = 1

Substitute values for Apple and Orange

Cranberry + 1/4+ 2/5= 1

Collect Like Terms

Cranberry = 1- 1/4- 2/5

Take LCM

Cranberry = \frac{20 - 5 - 8}{20}

Cranberry = \frac{7}{20}

The ratio is then represented as:

Cranberry:Apple:Orange = 7/20:1/4:2/5

Multiply through by 20

Cranberry:Apple:Orange = 20(7/20:1/4:2/5)

Cranberry:Apple:Orange = 20*7/20:20*1/4:20*2/5

Cranberry:Apple:Orange = 7:5:8

Which term describes the point where the three altitudes of a triangle intersect?
kumpel [21]

Answer: Option (B) is the correct answer.

Step-by-step explanation:

A point at which three altitudes of a triangle meet is known as orthocenter.

Whereas when a circle is inscribed in a triangle and it touches all the sides of a triangle then the center of circle is known as incenter.

When all the three medians of a triangle intersect each other then the point is known as centroid.

Circumcenter is a point where perpendicular bisectors on each side of a triangle bisect and this point is equidistant from all the vertices.

You have a function y= \dfrac{3}{2} \left(1+\sin  \left(\dfrac{2t+1}{2}\cdot \pi\right) \right).
Since the range of the function y=\sin x is [-1,1] you have that

-1\le \sin \left(\dfrac{2t+1}{2}\cdot \pi\right)\le 1 \\ 0\le 1+\sin \left(\dfrac{2t+1}{2}\cdot \pi\right) \le 2 \\ 0\le \dfrac{3}{2} \left(1+\sin \left(\dfrac{2t+1}{2}\cdot \pi\right) \right)\le 3.
Answer: The range of given function is [0,3] and the correct choice is C.
