Which geometric series converges ???

Answer:

46

Step-by-step explanation:

64 spaces. 18 empty

64 - 18 = 46

Final answer:

Jill currently has 46 stamps in her stamp book. For Jenny, the calculations show that if Lisa ended up with 6 chocolates, which is half of the remainder, then Jenny must have started with 14 chocolates initially.

Explanation:

To find out how many stamps Jill has now, we subtract the number of stamps she needs from the total capacity of the stamp book. If the stamp book has space for 64 stamps and Jill needs 18 more stamps to fill it, then:

Total stamp space in the book = 64

Stamps needed to fill the book = 18

Stamps Jill has now = Total stamp space - Stamps needed to fill the book

Stamps Jill has now = 64 - 18

Stamps Jill has now = 46 stamps

Therefore, Jill currently has 46 stamps in her stamp book.

Now, for Jenny's chocolates:

If Lisa has 6 chocolates, which is half of the remainder after Jenny ate two, we can calculate the original number of chocolates Jenny had. Since Lisa has 6, the remainder before Lisa received them was 12 (because 6 is half of 12). Therefore, if Jenny ate 2 chocolates before giving half to Lisa, she initially had:

Chocolates after eating 2 = 12 (remainder)

Chocolates before eating = 12 + 2

Chocolates Jenny had initially = 14

So, Jenny had 14 chocolates in the beginning, which is answer C. 14.

Final answer:

In an isosceles triangle with a perimeter of 22 cm and one side of 6 cm, the other two sides must be equal in length and must be 8 cm each to satisfy the perimeter condition.

Explanation:

The question asks for the possible lengths of the other two sides of an isosceles triangle with a perimeter of 22 cm, where one side is already known to be 6 cm. In an isosceles triangle, the two other sides must be of equal length because an isosceles triangle has two sides that are the same.

Let's denote the length of these two equal sides as 'x'. The perimeter of a triangle is the sum of the lengths of all three sides:

6 cm + x + x = 22 cm
2x + 6 cm = 22 cm
2x = 22 cm - 6 cm
2x = 16 cm
x = 8 cm

Therefore, the other two sides of the triangle must each be 8 cm long.

It's important to note that all three sides of a triangle must satisfy the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In this case, the other two sides cannot both be less than 6 cm, otherwise, they will not form a triangle with the third side of 6 cm. The solution provided meets this requirement.

Answer:

Step-by-step explanation:

You need to use trigonometry (SOHCAHTOA)

As from the focus angle -thetre- (65^o) you have the adjecent (x) and hypotenuse (the side opposite the right angle - 81.9m):

cos(θ) = adjacent/hypotenuse

cos (65) = x/81.9

as the opposite of dividing is mulitplying, you multiple both sides by 81.9

81.9*cos(65) = x

using calculator - in degree mode-

x = 34.6124

Thus it is the first choice, x = 34.61.

Answer:

The correct answer is first option

X = 34.61

Step-by-step explanation:

Points to remember

Trigonometric ratios

Sin θ  = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

From the figure we can see that a right angled triangle with base x and hypotenuse = 81.9.

One angle = 65°

To find the value of x

We have Cos θ = Adjacent side/Hypotenuse

Cos 65 = X/81.9

X = 81.9 * Cos 65

 = 81.9 * 0.4226  

 = 34.61

Therefore  X = 34.61

Answer:

AB - C² = 3x³ + x² + 6x - 9 ⇒ last answer

Step-by-step explanation:

* Lets study the problem to solve it

- The variables are:

# A = x²

# B = 3x + 2

# C = x - 3

* At first lets find AB

∵ A = x² and B = 3x + 2

∴ AB = x²(3x + 2)

∵ x² × 3x = 3x³ ⇒ same base so we added the power

∵ x² × 2 = 2x² ⇒ coefficient of x² is 1 multiplied by 2

∴ AB = 3x³ + 2x²

* At second find C²

∵ C = x - 3

∴ C² = (x - 3)²

- To solve bracket to the power of 2 use this rule:

# square the first term + 1st term × 2nd term × 2 + square the 2nd term

∴ (x - 3)² = (x²) + (x) (-3) (2) + (-3)² = x² - 6x + 9

∴ C² = x² - 6x + 9

* Now lets find AB - C²

∵ AB - C² = 3x³ + 2x² - (x² - 6x + 9) ⇒ multiply the bracket by -ve sign

∵ -ve × -ve = +ve

∵ -ve × +ve = -ve

∴ AB - C² = 3x³ + 2x² - x² + 6x - 9 ⇒ Add the like terms

∴ AB - C² = 3x³ + x² + 6x - 9

* AB - C² = 3x³ + x² + 6x - 9

Answer:

B. 0.56.

Step-by-step explanation:

That would be the number of sophomore / total number of people

= 77 / 137

= 0.56.

The probability that the randomly chosen person from this group is a sophomore is B. 0.56.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

Total number of people attended in the school event = 137

Number of sophomores in the group = 77

To find the probability, we have to divide the number of desired outcomes by the total number of outcomes.

Here total number of outcomes is 137 and the number of sophomores is 77.

Probability = 77 / 137 = 0.562 ≈ 0.56

Hence the probability is 0.56.

Answer: 7 feet long

7 feet.

The area of a rectangle is equal to its length times its height.

In this case, the area can be represented by 63 = 9 * w.

Divide both sides of the equation by 9 to get 7 = w.

Answer:

y = 3z - 2x

Step-by-step explanation:

Systems of equations can be solved by a number of know techniques, such as substitution, elimination or graphical approach.

We are required to solve the system of equations given via substitution;

2x + y = 3z

x + y = 6z

The question requires us to determine the value for y from the first equation, that could be substituted into the second equation.

We simply need to make y the subject of the formula from the first equation;

2x + y = 3z

To do this we subtract 2x on both sides of the equation;

2x + y -2x = 3z - 2x

y = 3z - 2x

This is the value of y from the first equation, that can be substituted into the second equation.

Answer:

2n² + n + 1

Step-by-step explanation:

                               4, 11, 22, 37

Difference between:  7, 11, 15

7,11,15 are all 4 apart. You divide the 4 by 2 to get 2n² (it is squared because you needed a second level to find the difference)

And then I knew you needed to put the original 2n² with the sequence we are trying to work out.

                                                                 2, 8, 18, 32

                                                                 4, 11, 22, 37

difference between the 2 sequences   2, 3 ,4 ,5 (which all has a difference of 1)  which means 1n or just  n.

So that's 2n² + n

I

The sequence is quadratic as the second difference is constant. The nth term expression can be established as 2n² for which the coefficient 2 is half of the second difference. Further, by matching the sequence to the nth term, we adjust the expression to 2n² + n + 1.

A key step to finding an expression for the nth term of this sequence is finding the difference between consecutive terms. For this particular sequence, you can see that the difference isn’t constant, thus, it's a quadratic sequence. However, if the second difference is constant, the nth term of the sequence is a quadratic:

The first differences are: 7(11-4), 11(22-11), 15(37-22), 19(56-37).

The second differences are 4(11-7), 4(15-11), 4(19-15).

Since the second difference is constant and equals to 4. We divide this by 2 to get 2. This is the coefficient of the n² term in our sequence. Thus, the first part of the nth term is 2n².

The next step is to write out the sequence of 2n², subtract this sequence from the original sequence, and identify the differences:

The difference above is clearly linear (increases by 1 each time) and thus the format for nth term has improved from 2n² to 2n²+n. So far this match has worked for the first 5 terms, but we need to look at the nth term to see if it works:

Original sequence: 4, 11, 22, 37, 56

Sequence of 2n²+n: 3, 10, 21, 36, 55

To match the original sequence, add 1 to each term in our sequence. The nth term is therefore 2n² + n + 1.

To find the product of the binomials (x + ut)(9x - 8ut), we use the FOIL method and combine like terms, resulting in the expression 9x² + uxt - 8u²t².

Explanation:

To find the product of the binomials (x + ut)(9x - 8ut), we will use the distributive property (also known as the FOIL method in this case), which involves multiplying each term in the first binomial by each term in the second binomial:

Combining like terms, the final product is:

9x² + 9uxt - 8uxt - 8u²t²

Since 9uxt and -8uxt are like terms, we can simplify further:

9x² + uxt - 8u²t²

Answer: [tex]m\angle6=50\°[/tex]

Step-by-step explanation:

You can observe in the figure two parallel lines that are intersected by a transversal and several angles are formed.

The angles m∠3 and m∠6 are located inside the parallel lines and on one side of the transversal, this angles are known as "Consecutive interior angles" and they are supplementary (which means that they add up 180°).

Therefore, you know that:

[tex]m\angle3+m\angle6=180\°[/tex]

So you can substitute m∠3=130° and solve for m∠6. Then you get:

[tex]130\°+m\angle6=180\°\\m\angle6=180\°-130\°\\m\angle6=50\°[/tex]

Answer:

The correct answer is m<6 = 50°

Step-by-step explanation:

From the figure we can see that,

AB ║CD

To find the value of m<6

From figure we get, m<3  = 130°

m<6 = m<2 (corresponding angles)

m<3 + m<2 = 180°   (Linear pair)

m<2 = 180 - 130 = 50°

m<6 = m<2 = 50°

Therefore the correct answer is m<6 = 50°
