How many 1/3 cup servings of juice are in a 5 cup container
vesna_86 [32]

Answer:

We can get 15  (1/3 cup) servings with a 5 cup container

Step-by-step explanation:

To solve this problem, we can easily divide 5 by (1/3)  to find how many servings can be obtained

5 /  (1/3)  

=  5 / (0.3333)

= 15

This can be checked by adding together (1/3) fifteen times

(1/3) + (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)+ (1/3)

= 15/3  = 5

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator
Dahasolnce [82]

Answer:

Volume, V = 3367.6 cm³

Step-by-step explanation:

Given the following data;

Diameter = 18.6 cm

Radius = diameter/2 = 18.6/2 = 9.3 cm

Pie, π = 3.14

To find the volume of the sphere;

Mathematically, the volume of a sphere is given by the formula;

Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3}

Where;

r is the radius of the sphere.

Substituting into the formula, we have;

V = \frac {4}{3} * 3.14 * 9.3^{3}

V =  4.186666667 * 804.357

Volume, V = 3367.6 cm³

I JUST NEED THESE 3 QUESTIONS
Sidana [21]

Answer:  

 

1.     What is the period and the amplitude of the sine function representing the position of the band members as they begin to play?

Answer:  Amplitude is 80 ft, period is 60 ft.

 

2.     Edna is sitting in the stands and is facing Darla. Edna observes that sine curve begins by increasing at the far left of the field. What is the equation of the sine function representing the position of band members as they begin to play?

Answer:  y = 80cos(x*π/30)+80

 

3.     As the band begins to play, band members move away from the edges, and the curve reverses so that the function begins at the far left by decreasing. Darla does not move. The sine curve is now half as tall as it was originally. What is the equation of the sine curve representing the position of the band members after these changes?

Answer: y = 40cos(x*π/30)+80

 

4.     Next, the entire band moves closer to the edge of the football field so that the sine curve is in the lower half of the football field from Edna’s vantage point. What is the equation of the sine curve representing the position of the band members after these changes?

Answer:  y = 40cos(x*π/30)+40
