Answer: The number of small cookies sold = 75

Step-by-step explanation:

GIven: Yesterday, the store sold 7 large cookies for every 5 small cookies.

Let 7x be the number of cookies and 5x be the number of small cookies.  (i)

They sold 30 more large cookies than small cookies.

i.e. 7x-5x=30           (Using (i))

\Rightarrow\ 2x=30\\\\\Rightarrow\ x=\dfrac{30}{2}\\\\\Rightarrow\ x=15

Thus, the number of small cookies sold = 5 (15)=75   (Using (i))

Hence, the number of small cookies sold = 75

Vikki [24]

Answer:

(a) 1/4

(b) answer in explanation

Step-by-step explanation:

In this question, we are told that we have a spinner and the spinner has 12 equal sized sections with three of the sections purple in color. We are now asked to calculate the probability of the spinner landing on the color purple.

Checking, we can see that this is a probability question. The spinner has the options of stopping at 12 different positions but amongst these 12 positions, 3 of the positions are painted purple. We now need to know the probability of the spinner landing on purple.

To get the probability of this, what we simply do is to divide the number of purple options by the total number of outcomes we have. The number of purple options is 3 while the total outcome we have is 12. The probability is thus P(of purple is) = 3/12 = 1/4

(b) we are asked to use words to describe the probability

From the probability in the question, what we can see is that if the spinner is spinner 4 different times, there is a chance that 1 out of all the chances will produce a result where we have the spinner landing on one of the purple color section.

What this actually means is that there is a 25% chance within every spin for the spin to land in the purple color section of the spinner

12/12 would be the fraction of all students...now subtract all of the fractions that represent students not in the volunteer programs...

12/12-2/12-4/12-1/12

(12-2-4-1)/12

5/12

So 5/12 of the student participate in volunteer programs.

If your cell phone bill was 67 Point $82 and there is a 7.5% late fee how much will your bill be with the late fee included
Ivenika [448]

\frac{7.5}{100}  =  \frac{x}{82}  \\ x =  \frac{82 \times 7.5}{100}  =  \frac{615}{100 }  = 6.15
82 + 6.15 = 88.15
the answer is $88.15
