You have 42 coins valued at $6.00. Some of the coins some are quartersFind the number you have of each. Set up and solve a system of equations needed to solve the problem.

Answers

Complete Question

Mark has 42 coins consisting of dimes and quarters. the total value of his coins is $6. How many of each type of coin does he have?

Answer:

The number of dimes = d = 30 dimes

The number of quarters = q = 12 quarters

Step-by-step explanation:

Let us represent

The number of dimes = d

The number of quarters = q

A dime is worth 10 cents = 0.10d

A quarter is worth 25 cents = 0.25q

Mark has 42 coins consisting of dimes and quarters.

q + d = 42...... Equation 1

q = 42 - d

The total value of his coins is $6.

0.1d + 0.25q = 6

We substitute 42 - d for q

0.1d + 0.25(42 - d) = 6

0.1d + 10.5 - 0.25d = 6

10.5 - 6 = 0.25d - 0.1d

4.5 = 0.15d

d = 4.5/0.15

d = 30 dimes

Solving for q

q = 42 - d

q = 42 - 30

q = 12 dimes

Therefore,

The number of dimes = d = 30 dimes

The number of quarters = q = 12 quarters

Objects on Jupiter weigh 240% of their weight on Earth. If an object weighs 30.5 pounds on Earth, how many pounds would it weigh on Jupiter?

Answers

Answer:

732

Step-by-step explanation:

It is 732 because if we start off with 30.5 and then get our 240%, what will happen next is that we will move the decimal spot 2 places on the 240%. So 240% now becomes .240 and NOT a percent yet because we need to do one more thing. After we do this we can then do 30.5x.240 which leads to 7.32. But because this number is too small and it even wouldnt make sense in this question, now we move the decimal spot to the right, so before we did left but now we go right. And when we do this it will finally give out answer of 732 pounds.

Randalstown rugby club play 20 matches and win 17 of there matches. What percentage of the matches did they win

Answers

Answer:

They won 85% of their matches

Step-by-step explanation:

Here, we want to calculate the percentage of wins

To do this, we apply the following formula;

number of wins/number of games * 100%

That would be;

17/20 * 100%

= 17 * 5 = 85%

Mary is planning to provide online math and french language tutoring sessions. The math session will be 45 minutes long, and the french sessions will be 30 minutes long. She plans to work no more than 30 hours per week and does not want to provide more than 30 french sessions in any one week l. Let m represent the number of math sessions, and f represent the number of french sessions mary will offer during the week. Which system of inequalities represents the constraints of the given situation?

Answers

Answer:

3/4m + 1/2f ≤ 30f ≤ 30

Step-by-step explanation:

Math session = 45 min = 3/4 hrFrench session = 30 min = 1/2 hrNumber of math sessions = m, total math hours = 3/4mNumber of French sessions = f, total French hours = 1/2f

Total hours constraint:

3/4m + 1/2f ≤ 30

Number of session constraint:

f ≤ 30

So the system is:

3/4m + 1/2f ≤ 30f ≤ 30

Answer:

3/4m + 1/2f ≤ 30

f ≤ 30

Functions

They are relations between input values and output values such that each input has one and only one output.

The function:

{(-3, 2), (-4, 2), (8, 3), (7, 1)}

Consists of four ordered pairs where the first component is the input value and the second value is the output value.

It can be identified that the output values are:

{2,3,1}

In any order, thus the first choice is correct.

When the expression 10^2021 − 2021 is evaluated, the result is a very large number.
You probably do not have enough time to perform the calculation. So, in an
effort to save you some time and paper, instead of evaluating the expression
10^2021 − 2021, determine the sum of the digits in the difference. How do I do this pls

Answers

Answer:

18,176

Step-by-step explanation:

Figure out an easier thing to do: 1000 - 2021 = 9,797.

Therefore, our answer will be like 9999999999999999999999997979. Out of all of these digits, there are only 2 that arent nines. We know the amount of digits since it's 10^2021 power. We will have one less since we are subtracting 2021. Therefore, 2020 digits in total. Now we know of those 2020 digits, 2 of them are 7, therefore 2018 of them are 9s. That means do 2018(9) + 2(7) = 14 + 18,162 =  18,176.

Solve the system of equations using elimination
2x + y = 5
-1x + y = 2

Answers

Answer:

(1, 3 )

Step-by-step explanation:

Given the 2 equations

2x + y = 5 → (1)

- x + y = 2 → (2)

Rearrange (1) expressing y in terms of x by subtracting 2x fro both sides

y = 5 - 2x → (3)

Substitute y = 5 - 2x into (2)

- x + 5 - 2x = 2

- 3x + 5 = 2 ( subtract 5 from both sides )

- 3x = - 3 ( divide both sides by - 3 )

x = 1

Substitute x = 1 into (3) for corresponding value of y

y = 5 - 2(1) = 5 - 2 = 3

solution is (1, 3 )
