A rectangular picture frame measures 10 cm by 12 cm. Do you want to triple the frames area by adding the same distance "x" to the length and the width. Write and solve an equation to find the value of "x". What are the new dimensions of the picture frame?

Answers

If the original frame area is x, then length*width=12*10=120=area=x. By tripling the frame's area, we get 120*3=360. However, we need to add a number x to both the length and width to equal the new area. Since length*width=area, and 10+x is the width and 12+x is the length, we get (10+x)*(12+x)=360. Expanding using the Distributive Property, we get 120+10x+12x+x^2=x^2+22x+120=360. Subtracting 360 from both sides, we get x^2+22x-240=0.Finding 2 numbers that add up to 22 and multiply to -240, we do a bit of guess and check ( we COULD use the quadratic formula too) to find 30 and -8 fit the bill. Therefore, x^2+30x-8x-240=0=
x(x+30)-8(x+30)=(x-8)(x+30). To make the expression equal to 0, since 0 multiplied by anything is 0, we have to figure out when x-8 and x+30 equal 0, which is when x=8 and -30 respectively (To do this, you could add 8 from both sides to turn x-8=0 to x=8, and something similar to -30). Plugging each one in, we get (10+(8))*(12+(8))=18*20=360. To make sure there aren't 2 solutions, we get that the new width is 10-30=-20, which clearly can't be negative , making x equal to 8.

Suppose a card is drawn from a deck of 52 playing cards. what is the probability of drawing a 3 or a queen?

Answers

In a deck of cards, there is a 3 in every suit...that's four 3's.
There are also a queen in every suit...that's four queens as well.
Therefore, there are 8 cards in the deck which are either 3 or queens.
8/52 is base probability. Reduce by dividing out a 4 from both terms.

P(drawing a 3 or queen) = 4/13 

Final answer:

The probability of drawing either a 3 or a Queen from a standard deck of 52 playing cards is 2 / 13, or approximately 15.38%.

Explanation:

The question asks for the probability of drawing either a 3 or a Queen from a standard deck of 52 playing cards. There are four 3s and four Queens in a standard deck, making a total of eight specific cards that fulfill our criteria out of 52. To calculate this probability, we divide the number of favorable outcomes (drawing a 3 or a Queen) by the total number of outcomes (total cards in the deck).

The formula for calculating the probability, P(A), of an event A (in this case, drawing a 3 or a Queen) is:

P(A) = Number of favorable outcomes / Total number of outcomes

Therefore, P(3 or Queen) = 8 / 52 = 2 / 13. This simplifies to approximately 0.1538 or 15.38%.

This means that when you draw a card from a standard deck of 52 playing cards, you have approximately a 15.38% chance of drawing either a 3 or a Queen.

What is the probability of winning tokens? a. 0.54 c. 0.69 b. 0.63 d. 0.87

Answers

find how many are gimmel or hay
45 gimmel and 24 hay
total is 45+24=69

69/100 or 69% chance of winning or 0.69

answer is C (confusing because C is 2nd option)

The probability of winning tokens is 0.69. Therefore, the option C is the correct answer.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes.

Given that, dreidel is spun 100 times, with the following results: nun =10, gimel =45, hay =24 and shin =21.

A player wins tokens if the dreidel lands on either gimel or hay.

Here, probability of getting gimel is 45/100

The probability of getting hay is 24/100

So, the probability of an event is 45/100 +24/100

= 69/100

= 0.69

Therefore, the option C is the correct answer.

F(x)=T-2(X+4)^2 where t is the constant. If f(-8.3)=f(a) and a > 0 what is the value of a ?

Answers

We are given the equation:

F (x) = T – 2 (x + 4)^2                      ---> equation 1

 

Since we know that f (-8.3) = f(a) and a>0, therefore from equation 1 we can generate that:

(x + 4)^2 = (a + 4)^2

(-8.3 + 4)^2 = (a + 4)^2

(-4.3)^2 = (a + 4)^2

(a + 4)^2 = 18.49

a + 4 = 4.3

a = 0.3

Name the property illustrated by each statement:

2. If x=3y and 3y=16. then x=16

Answers

Final answer:

The first statement demonstrates the Subtraction Property of Equality, and the second statement shows the Transitive Property of Equality, both of which are fundamental in solving linear equations.

Explanation:

The property illustrated by each statement:

If x+9=2, then x+9-9=2-9. This is an example of the Subtraction Property of Equality, which states that if you subtract the same number from both sides of an equation, the two sides remain equal.If x=3y and 3y=16, then x=16. This is known as the Transitive Property of Equality, where if one value equals a second value, and the second value equals a third value, then the first value equals the third value.

Understanding these properties helps in solving linear equations and applying basic operations in algebra.

Final answer:

The properties illustrated are the Subtraction Property of Equality and the Transitive Property of Equality, used in solving linear equations.

Explanation:

The question is asking to name the property illustrated by each statement:

Subtraction Property of Equality: If x+9=2, then x+9-9=2-9. This shows that if you subtract the same number from both sides of an equation, the equality is maintained.

Transitive Property of Equality: If x=3y and 3y=16, then x=16. This property states that if one quantity equals a second, and the second quantity equals a third, then the first quantity equals the third.

These properties are fundamental in solving linear equations and are used to manipulate and solve equations for a specific variable.

A rectangular field is nine times as long as it is wide. If the perimeter of the field is 1600 feet, what are the dimensions of the field?

Answers

Final answer:

The width of the field is 80 feet, and the length is 720 feet, calculated using the perimeter formula and the given ratio of length to width.

Explanation:

To determine the dimensions of the rectangular field, we need to set up two equations based on the given information that the field's length is nine times its width and that the perimeter is 1600 feet. We'll let w represent the width of the field and l represent the length.

Since the field's length is nine times its width, we can express this as l = 9w. The perimeter P of a rectangle is given by P = 2l + 2w. Since we know the perimeter is 1600 feet, we can use this to create the equation 1600 = 2(9w) + 2w, which simplifies to 1600 = 18w + 2w.

Combining like terms gives us 1600 = 20w, and solving for w gives us w = 1600 / 20, so w = 80 feet. Knowing w, we can find l by multiplying the width by 9: l = 9w = 9 × 80 = 720 feet.

Therefore, the dimensions of the field are a width of 80 feet and a length of 720 feet.

Answers

Yes 

the second option is correct
Final answer:

Yes, it is possible to draw a plane that includes a line and a third point not on the line. In mathematics, a plane can be defined by three points. Therefore, the two points on the line and the third point not on the line can be used to define the plane.

Explanation:

Yes, it is indeed possible to draw a plane that includes a line and a third point not on the line. The definition of a plane in mathematics is that it's a two-dimensional surface that extends infinitely along its length and width, which can be defined by three points. Considering you have two points on the line, and a third point that's not on the line, you could use these three points to define your plane. It doesn't matter whether the three points are collinear or not, the plane can still be defined. The key is that you need at least three non-collinear points to define a plane.
