A jawbreaker candy machine has 25 red jawbreakers, 30 green jawbreakers, 15 yellow
MArishka [77]
<h3>Answer: Choice C, 2/3</h3>

============================================

Work Shown:

A = # of candies that are not green

A = (# of red)+(# of yellow)+(#  of blue)

A = 25+15+20

A = 60

B = # of candies total

B = (# of red)+(# of green)+(# of yellow)+(# of blue)

B = 25+30+15+20

B = 90

P(not green) = probability of selecting candy that is not green

P(not green) = (# of candies not green)/(# of candies total)

P(not green) = A/B

P(not green) = 60/90

P(not green) = (2*30)/(3*30)

P(not green) = 2/3

Answer:

1/2 ornament in an hour

Step-by-step explanation:

Given

Orna\ ments = 2

Time = 4

Required

Determine the ornaments per hour

This question implies that we calculate the unit rate.

Unit\ Rate = \frac{Orna\ ments}{Time}

Substitute values for Time and number of ornaments

Unit\ Rate = \frac{2}{4}

Unit\ Rate = \frac{1}{2}

<em>This implies that Constance can decorate 1/2 ornaments in an hour</em>

What is the volume of a small cone if:
Amiraneli [1.4K]

Answer:

Volume of smaller cone =301.44

Step-by-step explanation:

First let angle of cone be\alpha.

then sin(\alpha ) = 3/5       (For bigger triangle)

Same cone angle is for smaller one because they are similar.

cos(\alpha ) = 4/5

Now for smaller cone radius be R

3/5 =R/Slant height

Slant height =5/3R

Lateral surface area =\frac{1}{2}R^{2}\beta  [R = slant height]  

Given lateral surface area =60\pi =\frac{1}{2}(\frac{5R}{3} )^{2} \beta   ...................................1

2\pi R=\frac{5R}{3}\beta        ................................................2

\beta=\frac{6\pi }{5}

Put angle beta in equation 1 and find the value of R

R =6 cm

Height =\frac{4R}{3}

Thus volume =\frac{1}{3}\pi6^{2}*8

                     =301.44
