A ribbon is 6½ feet long.

How many 1 1/4 -foot-long pieces can be cut from the 6½ feet?

How much ribbon will be left over?

b) Now show how you would solve the same problem using math

Answer: step 1:

wickets 2 and 9, (16,18) and (15,43) = 25.02ft

wickets 9 and 8, (15, 43) and (37,65) = 31.11 ft

wickets 8 and 5, (37, 65) and (63,39) = 36.7 ft

wickets 5 and 3, (63, 39) and (41, 17) = 31.11 ft

wickets 3 and 2, (41, 17) and (16, 18) = 25.02 ft

The magnitude of the x-component of this vector is 9.05m.

The angle of inclination of the vector is calculated as;

θ = 90 ⁰ - 48.4 ⁰

θ = 41.6 ⁰

The magnitude of the x-component of the vector is calculated as;

Vx = 12.1 m x cos ( 41.6 )

Vx = 9.05 m

A vector can be represented by an ordered set of numbers, called components, that indicate the magnitude and direction of the vector in a particular coordinate system. The components of a vector can be added or subtracted using vector addition and subtraction, and multiplied by a scalar (a real number) using scalar multiplication.

Vectors can be visualized as arrows in a two- or three-dimensional space, where the length of the arrow represents the magnitude of the vector, and the direction of the arrow represents the direction of the vector. Vectors can also be represented as matrices, which can be used to perform various operations on vectors, such as dot product and cross product.

Complete Question:-

Answer:

2.25

Step-by-step explanation:

Notice how the common ratio is -1/3, which means the series passes part 1 of the convergence test because -1/3 is in between -1 and 1.

We can also represent this as a summation series of

\(Σ3( - \frac{1}{3} ) {}^{n - 1} \)

Since we can represent this a summation series, we can use that convergent value is equal to

\( \frac{a _{1} }{1 - r} \)

where a1 is initial term and r is common ratio.

R is -1/3

A1 is 3.

\( \frac{3}{1 - \frac{ - 1}{3} } = \frac{3}{ \frac{4}{3} } = 2.25\)

So the answer is 2.25

The bicycle is moving at a speed of 14,356 meters per hour.

Here, we are given that the wheel of a bicycle is spinning at the rate of 150 revolutions per minute.

The diameter of the wheel is 20 inches

⇒ radius = 10 inches

⇒ circumference of the wheel = 2 × π × 10

= 20π

Thus, the wheel will cover a distance of (20π × 150) inches in a minute

= 300π

now, we know that 1 inch = 0.254 meters

⇒ 300π inches = 300π × 0.254

= 76.2π

Thus, the bicycle covers 76.2π meters in a minute

⇒ it'll cover 76.2π × 60 meters in an hour

= 4572π

= 4572 × 3.14

= 14,356.08

Thus, the bicycle is moving at a speed of 14,356 meters per hour.

Answer:

The price of a child ticket in dollars $8.00

Step-by-step explanation:

Answer:

180 ft^3

Step-by-step explanation:

volume=lwh

15 * 2* 6 = 180 ft^3

*change 24 inches to 2 feet*

Answer:

180 ft³

Step-by-step explanation:

To find the volume of a right rectangular prism, the equation is length x width x height. So, you would do 2 x 6 x 15, because 24 inches is 2 feet and the rest is given. And so, 2 x 6 x 15 = 180, so your answer is 180 ft³.

Answer: £9.3 more

Step-by-step explanation:

Price for winter tickets: £18 + £18 + £14 = £50

Summer tickets pricing:

£18 + 20% = £21.6  

£14 + 15% = £16.1

Price for summer tickets: £21.6 + £21.6 + £16.1 = £59.3

Subtract winter tickets from summer tickets for difference:

£59.3 - £50 = £9.3

The number of boys and girls in a team after the selection of participants are 2 and 3, respectively

The number of boys are girls are given as

Boys = 28

Girls = 42

Sections = 6

To form teams with the same number of boys and girls on each team, we need to determine the greatest common factor (GCF) of the number of girls and the number of boys.

Factors of 28: 1, 2, 4, 7, 14, 28

Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42

The greatest common factor of 28 and 42 is 14.

So, we have

Boys = 28/14 = 2

Girls = 42/14 = 3

This means that each team has 2 boys and 3 girl

Do all the operations in order by following the PEMDAS method.

Answer:

x = 80

Step-by-step explanation:

if ray RU bisects <QRS that means it divided the angle into two equal parts

then we can write the following equation to find the value of x:

<SRU = <QRU

50 = (x/2 + 10) subtract 10 from both sides

40 = x/2 multiply both sides with 2

80 = x

<QRS = 100 because it's the sum of <SRU and <QRU

Answer:

I think x = 2

Step-by-step explanation:

If we input 2 into x, it would look like this: 2(2) + 1 = 5

Performing the operation of taking the absolute value of each element in the matrix will make the lower left element the largest.

To determine which operation will make the lower left element the largest, we need to compare the values of the lower left element with the other elements in the matrix. The given matrix is:

2 -1 -4

7 3 4

5 5 -1

2 1 -1

Taking the absolute value of each element means disregarding the sign and considering only the magnitude of the values. By taking the absolute value of each element in the matrix, the negative values become positive, and the positive values remain unchanged.

After taking the absolute value, the matrix becomes:

2 1 4

7 3 4

5 5 1

2 1 1

Now, if we compare the lower left element (-1 in the original matrix) with the elements in the new matrix, we can see that the element in the lower left corner (1 in the new matrix) is the largest among them. Therefore, taking the absolute value of each element in the matrix will make the lower left element the largest.

The probability that a randomly chosen return shows an adjusted gross income of $50,000 or more is 33.2%.

For mutually exclusive events, use the following addition rule:

        P(A or B) = P(A) +P(B)

The corresponding probabilities is :

   P( income > $50000) = P( >50)

= P(50 - 90) +P( 100 - 499) +P( ≥ 500)

= 0.215 + 0.100 +0.006

= 0.321

Therefore, the probability of a random selection returning is

P( income > 50000) = 0.321

Now ,

P( income ≥ 50000 and ≥ 100000 ) = P( > 100000)

= 0.100 + 0.006

= 0.106

The Probability Condition is:

   P(A/B) = P(A and B) / P(B)

Therefore,

P( ≥ $100000 / $ $50000)

=   P( ≥ $100000 and $ $50000)/ P( ≥ $50000)

= 0.106/ 0.321

≈ 0.3302

= 33.2%

Therefore, the conditional probability of earning at least $50000 and more is 33.2%

For all proportional relationships, the true statements are:

A, D, and E.

A proportional relationship between two variables x and y is written as:

y = k*x

Now let's analyze each of the given statements:

A) The origin is the point (0, 0).

If you evaluate the general equation in x = 0 you get:

y = k*0 = 0

So yes, this equation passes through the point (0, 0).

B) This is false, as we saw above.

C) The formula for the constant of proportionality is:

y = k*x

y/x = k

So we can see that k = rise/run

the statement is false.

D) Yes, this is true, a general linear equation is:

y = a*x + b

Where a is the slope and b is the y-intercept, particularly if the y-intercept is zero, then we have a proportional relation.

E) Yes, slope, unit rate, constant of proportionality, are all equivalent terms for a proportional relation.
