Daniel [21]

Answer:Jarvis's class average is 75

Step-by-step explanation:

The total possible average score for the math course is 100

a) If the teacher rates homework at 10%, it means that the total possible score for homework

is 10/100 × 100 = 10

If his homework average is 93, then his score would be

(93×10)/100 = 9.3

b) If the teacher rates quizzes at 30%, it means that the total possible score for quizzes

is 30/100 × 100 = 30

If his quiz average is 82, then his score would be

(82×30)/100 = 24.6

c) If the teacher rates test at 40%, it means that the total possible score for quizzes

is 40/100 × 100 = 40

If his quiz average is 72, then his score would be

(72×40)/100 = 28.8

d) If the teacher rates final exam at 20%, it means that the total possible score for quizzes

is 20/100 × 100 = 20

If his final exam is 60, then his score would be

(60×20)/100 = 12

Jarvis's class average would be

9.3 + 24.6 + 28.8 + 12 = 74.7

Lemonade. You want to buy a new car, and you know the model you want. The model has three options, each one of which you can eit

IRISSAK [1]

Answer:

3125

Step-by-step explanation:

The model has three options, each one of which you can either take or not take.

Let us represent taking an option with 1 and not taking an option with 0

1. 0 0 0 ( taking none of the options)

2. 0 0 1

3. 0 1 0

4. 0 1 1

5. 1 0 0

6. 1 0 1

7. 1 1 0

8. 1 1 1 ( taking all three options)

Also you have a choice of four different colors, therefore, total number of possible combinations are

8*4= 32

Hence the largest number of cars having same options and colors is

100,000/32

3125 cars

A vending machine sells chips at $0.40 and candy at $0.50. Last month, the vending machine yielded $139.80 with a sale of 298 it

Sidana [21]

Let us say... . the machine sold packages of chips at the amount of "p",
and the machine also sold, last month as well, an amount of "c" candies

now, last month the machine sold total 298 items
that yielded a revenue of $139.80

so...whatever "p" and "c" are, we know that, their sum for last month is,
298, so,
p + c = 298

how much revenue in sales of chips? well, they're 0.40 per package,
so, whatever "p" is, the machine sold 0.40 * p or 0.4p in revenue

how much for the candies? well, they're 0.50 for each, so
whatever "c" is, 0.50 * c or 0.5c in revenue

we know, their total revenue yield was 139.80
so
0.4p + 0.5c = 139.8

now... do substitution from the 1st equation on the 2nd one, and solve for "p", or packages of chips

that is $\begin{cases}
p+c=298\to c=\boxed{298-p}
\\ \quad \\
0.4p+0.5c=139.8
\\
\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\\
0.4p+0.5(\boxed{298-p})=139.8

\end{cases}\impliedby \textit{solve for "p"}$
