How many gallons of a 90​% antifreeze solution must be mixed with 80 gallons of 25​% antifreeze to get a mixture that is 80​% ​antifreeze?

Answers

Answer:

x=440 gaL 90 % Antifreeze II

Step-by-step explanation:

In the problem, there are two types of antifreeze

antifreeeze I and

antifreeze II

antifreeze I 25 ----80 gal

Antifreeze II 90 ----- x gal

Total 80 ---------------- (80 + x ) gal

(25*80)+(90*x)=80(80+x)

2000+90x=6400+80x

90x-80x=6400-2000

10x=4400

divide both sides by 10 we have

x= 440

x=440 gaL 90 % Antifreeze II

Which is A Prime Number? 7 33 27 63

Answers

Answer:

7 is the only prime number

Step-by-step explanation:

7 is a prime number because it has only two distinct divisors: 1 and itself (7). As a consequence, 7 is only a multiple of 1 and 7.

The prime number among the given numbers is 7.

What are Prime Numbers?

Prime numbers are positive integers greater than 1 that have no divisors other than 1 and themselves. In other words, a prime number is a number that cannot be evenly divided by any other number except 1 and itself.

We have the numbers as 7, 33, 27 and 63.

The prime numbers are numbers that are divisible only by 1 and themselves, with no other factors.

Among the given numbers, 7 is a prime number because it is only divisible by 1 and 7.

Since 33 is divisible by 1, 3, 11, and 33.

and, 27 is divisible by 1, 3, 9, and 27.

and, 63 is divisible by 1, 3, 7, 9, 21, and 63.

Therefore, the prime number among the given numbers is 7.

An NHL hockey player has 59 goals so far in a season. What are the possible numbers of additional goals the player can score to match or break the NHL record of 92 goals in a season?

Answers

Answer:

33 additional goals

Step-by-step explanation:

59+g is greater than or equal to 92 subtract 59 from both sides leaving the answer g is greater than or equal to 33

The hockey player would have to score:

33 goals to match the record 34 goals to break the record

In order the match the record, the hockey player needs to score a certain number of goals that will take them to the record of 92. That number is:

= 92 - 59

= 33 goals

If they however want to break the record, the need to score more than 92 goals. The least number of goals they can score to do so is:

= Number of goals to match record + 1

= 33 + 1

= 34 goals

In conclusion, the player would have to score 33 goals to match the NHL record but 34 to break it.

The independent variable is pies, and the dependent variable is apples.
D)
The independent variable is apples, and the dependent variable is pies.
Im

Answers

Answer:

Option (D)

Step-by-step explanation:

When we make a pie we will need apples.

That means number of pie baked will always depend on the number of apples available or number of apples used.

So the number of apples used will be independent variable.

Since number of pie will always depend on the number of apples used,

Number of pie baked will be a dependent variable.

Therefore, Option (D) will be the answer.

Step-by-step explanation:

Suppose you work as a clerk at a local retail store earning $6 per hour. The amount of your weekly paycheck (before taxes are taken out) could be written F(x) = 6x.

16. What is the independent variable in this function and what does it represent?

Answers

Answer:

x is the independent variable and it represents the number of hours worked per week by the clerk.

Step-by-step explanation:

An independent variable refers to a variable in model that is varied or changed in order to examine its effect on another variable. The other variable is called a dependent variable.

A dependent variable is a variable in a model that changes as a result of a change in the independent variable.

From the question, x is the independent variable and its represent the number of hours worked by the clerk.

F(x) represents the amount of your weekly paycheck and it is the dependent variable that changes as the number of hours worked, x, changes.

For example, since we are given:

F(x) = 6x ............................... (1)

Where;

F(x) = = depemdent variable = Amount of weekly paycheck (before taxes are taken out)

6 = coefficient of x = Earning per hour

x = Independent variable = Number of hours worked

Assuming x = 1, we can substitute this into equation (1) and have:

F(x) = 6 * 1 = $6

But when x = 2, we have:

F(x) = 6 * 2 = $12

Therefore, the dependent variable F(x) changes from $6 weekly to $12 weekly as the independent variable x changes form 1 hour to 2 hours weekly.

Dr. Hernandon believes that time spent playing video games is negatively associated with reading fluency. He asks parents to record the average number of hours their children spend playing video games each day. He compares these hours with scores on the Woodcock-Johnson reading test. His correlation coefficient confirms that as hours playing video games increases, reading fluency decreases. Which correlation coefficient would fit his data?

Answers

Options :

A) - 0.89

B.) + 0.34

C.) + 0.89

D.) - 0.34

Answer: A) - 0.89

Step-by-step explanation:

Since Dr. Hernandon has been able to establish that a strong negative relationship exists between the number of hours spent playing video games and reading fluency, hence looking through the options provided, the most suitable will be - 0.89, this is because the negative sign implies a negative correlation or association between the two variables (that is decrease in one leads to a corresponding increase in the other and vice-versa) also, the strength of correlation exists in how close the value of the correlation Coefficient is to 1 or - 1. Values closer to 1 or - 1 are strongly correlated while those closer to zero exhibits a weak association. Correlation Coefficient value of 0 implies that there is no association between both variables.

Composition f(g(x)) and g(f(x)) function f and g are shown on the graph. Which statements describe the composition? Check all that apply

Answers

Answer:

Step-by-step explanation:

f(g(x) = g(f(x)) for at least one value of x.

The composition of f and g is commutative.

f(g(0)) = 5 and g(f(-2.5)) = 5.

The graphs show that function composition is not commutative.

Answer:

A, C, D, and E

 f(g(x)) = g(f(x)) for at least one value of x.

 f(g(0)) = 5 and g(f(–2.5)) = 5.

Both f(g(x)) and g(f(x)) have the same domain.

Answer:

#7.  JK = 1

Step-by-step explanation:

So all these problems are similar in the fact that you are given three pieces of information and you need to determine x.  Let's look at #7.

We are to find the length JK but we are given it in terms of x.  To find the length, we need to find x.  Using the information we have about KL and JL, we can find this.  Note, the value of JL is 5, and the value of KL is x + 8.

JK + KL = JL

( 2x + 9 ) + ( x + 8 ) = 5

3x + 17 = 5

3x = -12

x = -4

Now that we have the value of x,  we can find the value of JK:

JK = 2x + 9

JK = 2(-4) + 9

JK = -8 + 9

JK = 1

Hence, the length of JK is 1.

Using this same basic idea, you can solve all of these problems.

Cheers.

Two brothers, Mark and Walter, each inherit $20000. Mark invests his inheritance in a savings account with an annual return of 2.5%, while Walter invests his inheritance in a CD paying 6.1% annually. How much more money than Mark does Walter have after 1 year?

Answers

Answer:

$720

Step-by-step explanation:

$20000 - 100%

$x. - 2.5%

x=(20000*2.5)/100=500

20000+500=$20500 in one year (Mark)

20000 - 100

x. - 6.1

x= (20000*6.1)/100 = 1220

20000+1220= $21220 (Walter)

21220-20500= $720 more (Walter will have after 1 year)
