Step-by-step explanation:

From the question given above, the following data were obtained:

Adjacent = 6 cm

Hypothenus = 15 cm

Angle Y =?

Angle Y can be obtained by using the cosine ratio as illustrated below:

Cos Y = Adjacent / Hypothenus

Tariq is a high school basketball player. In a particular game, he made some two point shots and some free throws (worth one point each). Tariq made a total of 6 shots altogether and scored a total of 8 points. Write a system of equations that could be used to determine the number of two point shots Tariq made and the number of free throws he made. Define the variables that you use to write the system.

Answers

Answer:

y=two point shots

x=free throws

system of equations

x+y=6

x+2y=8

Step-by-step explanation:

let y = two point shots

x = free throws

Total shots = 6

i.e x+y = 6

Total points = 8

2y+x = 8

one shot of y = 2 points

one shot of x = 1 points

system of equation

x+y=6

x+2y=8

The system of equations that can be used are x + y = 6 and 2x + y = 8, where x is the number of two point shots and y is the number of free throws.

What does a System of Linear Equations define?

Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.

System of linear equations involve two or more linear equations.

Given that,

Tariq made some two point shots and some free throws which is worth one point each.

Let x be the number of two point shots and y be the number of free throws that Tariq made.

Given, Tariq made a total of 6 shots altogether.

x + y = 6

Total points scored = 8 points

Score for two point shot = 2

Score for free throws = 1

Equation can be written as,

2x + y = 8

The system of equations are,

x + y = 6 and 2x + y = 8

Hence the system of equations are x + y = 6 and 2x + y = 8.

3/4 (x + 9) = 15
It’s a 2 step equation

Answers

To solve the equation 3/4 (x + 9) = 15, we can follow these steps:

Simplify the expression on the left-hand side by distributing the 3/4:

3/4 (x + 9) = 15

3/4x + 27/4 = 15

Subtract 27/4 from both sides to isolate the variable term:

3/4x + 27/4 - 27/4 = 15 - 27/4

3/4x = 33/4

Multiply both sides by the reciprocal of 3/4, which is 4/3, to solve for x:

(4/3) * 3/4x = (4/3) * 33/4

x = 11

Therefore, the solution to the equation 3/4 (x + 9) = 15 is x = 11.

Ethan had planned to visit his local post office on Saturday to exchange $400
or euros. The exchange rate for that day was $1 = 1.25 E
However, due to unforseen circumstances, Ethan arrived at the post office after

it closed on that day. He therefore had to wait until the following Monday to
exchange his $400 for euros. The exchange rate on Monday was $1 = 1.20 E
a) How many fewer euros did he receive due to this delay? |20
b) What percentage loss was caused by this delay?

Answers

The amount of fewer euros he would receive as a result of the delay is 20 E.

The percentage loss that was caused by the delay is -4%.

What is the fewer euros received and the percentage loss?

Exchange rate is the rate at which one unit of a currency can buy another currency. In this question, the value of Euros appreciated by Monday. This is because $1 buys less Euros on Mondays. On the hand, dollars depreciates in value.

Amount of fewer Euros received = value of euros if it were exchanged on Friday - value of euros if it was exchanged on Monday

Value of euros if it were exchanged on Friday = 1.25 x 400 = 500 E

Value of euros if it was exchanged on Monday = 1.20 x 400 = 480 E

Difference = 500 E - 480 E = 20 E

Percentage loss = (Euros received on Monday / Euros that would have been received on Friday) - 1

Percentage loss = (480 / 500) - 1 = -0.04 = -4%

Answers

The right response is 400%. In other words, Johnny moves at four times the pace of Jane.

We must compare the speeds of Johnny and Jane in relation to one another in order to get their ratio. According to the issue, Jane moves at a pace that is 1/4 that of Johnny. In other words, Jane moves at a speed that is one-fourth that of Johnny.

We may compare the speeds as a fraction to figure out the ratio:

Johnny's speed divided by Jane's speed equals 4/1.

This indicates that Johnny is moving at a speed that is four times that of Jane. We can express Johnny's speed as 400% of Jane's speed in percentage terms.

4. Amy, Betty and Carol have 96 books altogether. Betty has 6 books less than Amy and Carol has half as many as Betty. How many books does each girl have?​

Answers

The Amy has 42 books, Betty has 36 books, and Carol has 18 books.

Let's set up equations to represent the given information:

Let A represent the number of books Amy has.

Let B represent the number of books Betty has.

Let C represent the number of books Carol has.

Let's say Amy has x books.

Betty has 6 books less than Amy, so Betty has (x - 6) books.

Carol has half as many books as Betty, so Carol has (x - 6)/2 books.

According to the problem, the total number of books they have is 96.

So, we can write the equation:

x + (x - 6) + (x - 6)/2 = 96

To solve the equation, we can simplify it by multiplying through by 2 to remove the fraction:

2x + 2(x - 6) + (x - 6) = 192

2x + 2x - 12 + x - 6 = 192

5x - 18 = 192

5x = 210

x = 42

Amy has 42 books.

Betty has (42 - 6) = 36 books.

Carol has (36)/2 = 18 books.

The unit rate of computers per day using the graph is that 12 computers are made per day.

What is a unit rate?

The unit rate is how many units of quantity correspond to the single unit of another quantity. We say that when the denominator in rate is 1, it is called unit rate. Unit rates is said to be the amount of something in each unit or per unit.

How to find the unit rate of computers per day

To obtain the unit rate of computers sold per day using the graph, we need to obtain the slope of the graph, which is the change in y per change in x

So, it is given by:

\(\text{Slope} = \dfrac{\text{change in y}}{\text{change in x}}\)

\(\text{Slope} = \dfrac{\text{y}_2-\text{y}_1}{\text{x}_2-\text{x}_1}\)

\(\text{y}_2 = 60 , \ \text{y}_1 = 36 , \ \text{x}_2 = 5, \ \text{x}_1 = 3.\)

\(\text{Slope} = \dfrac{(60 - 36)}{(5 - 3)} = \dfrac{24}{2} = 12\)

\(\bold{Slope = 12}\)

Unit rate = 12 computers per day.

You pick a marble, roll a die, and pick a card. How many outcomes are possible?

You pick a marble, roll a die, and pick a card. How many outcomes are possible?

Answers

The total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.

How to determine How many outcomes are possible

To determine the number of possible outcomes, we need to consider the number of outcomes for each event and then multiply them together.

1. Picking a marble: Let's assume there are n marbles to choose from. If there are n marbles, then the number of outcomes for this event is n.

2. Rolling a die: A standard die has 6 sides numbered 1 to 6. Therefore, the number of outcomes for this event is 6.

3. Picking a card: A standard deck of cards has 52 cards. Hence, the number of outcomes for this event is 52.

To find the total number of possible outcomes, we multiply the number of outcomes for each event together:

Total number of outcomes = (number of outcomes for picking a marble) × (number of outcomes for rolling a die) × (number of outcomes for picking a card)

Total number of outcomes = n × 6 × 52

Therefore, the total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.

Answers

Answer ( 10, -2 )

Step by step

2x + 5y = 10
3x - 11y = 52

Addition method - this method is also called the elimination method. In this method, we add two terms with the same variable, but opposite coefficients, so that the sum is zero.

First we need to adjust the x value so they can be eliminated

3 (2x + 5y = 10) multiply all terms by 3
-2 ( 3x - 11y = 52) multiply all terms by -2

6x + 15y = 30
-6x + 22y = -104
-————————-
0x + 37y = - 74

Divide both sides by 37 to solve

37/37 y = -74/37
Simplify

y = -2

Now substitute value of y = -2 into equation to solve for x

2x + 5 (-2) = 10
2x -10 = 10
Add 10 to both sides to isolate variable

2x -10 + 10 = 10 + 10

2x = 20

Divide both sides by 2 to solve for x

2/2 x = 20/2

x = 10

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

If I had 60 units needed and units per case was 14 how many cases and additional units I got

Answers

Answer:

Step-by-step explanation:

60 divided by 14 is 4 with a remainder of 4

The additional number of units required is 10 units.

Given that:

Total number of units needed = 60 units

Total number of units per case = 14

How to find the total number of cases required for the given question?

So, the total number of cases required=Number of units needed / number of units per case.

Number of cases required = 60/14 = 4.285 (this means that 5 cases are required as 4 cases won't be up to 60 units)

With 5 cases, we have exceeded the required units needed :

Additional units will be : (14×5) - 60

Additional units = 70 - 60 = 10 units

Therefore, the additional number of units required is 10 units.

Answers

The correct answer is 3/2. In this case, x = 3/2, and its square, (3/2)^2 = 9/4, is rational. x satisfies the given condition.option (c)

To explain further, we need to understand the properties of rational and irrational numbers.

A rational number can be expressed as a fraction of two integers, while an irrational number cannot be expressed as a fraction and has non-repeating, non-terminating decimal representations.

In the given options, (a) √5102.0 (£) and (b) √2 are both irrational numbers.

Their squares, (√5102.0)^2 and (√2)^2, would also be irrational, violating the given condition. On the other hand, (d) 4/5 is rational, and its square, (4/5)^2 = 16/25, is also rational.

Option (c) 3/2 is rational since it can be expressed as a fraction. Its square, (3/2)^2 = 9/4, is rational as well.

Therefore, (c) 3/2 is the only option where x is rational, but its square is irrational, satisfying the condition mentioned in the question.

In summary, the number x that satisfies the given condition, where x^2 is irrational but x is rational, is (c) 3/2.option (c)
