Using some mathematical operations, we know that each player's headband and wristband are made from 16.18 inches of fabric and 8.63 inches of fabric.

A mathematical function known as an operation converts zero or more input values into a precisely defined output value.

The quantity of operands affects the operation's arity.

Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction are collectively referred to as PEMDAS.

So, given that we've done it:

There are 35 players.

There are two coaches.

The cloth on the headbands measures 598.66 inches in length.

Just for the players, the wristbands include 302.05 inches of fabric.

Each player's headband's fabric length is specified by:

= Total inches/Total number of persons

= 598.66/37

= 16.18 inches

Each player's wristband's fabric length is specified by:

= Total inches/Number of persons

= 302.05/35

= 8.63 inches

Therefore, using some mathematical operations, we know that each player's headband and wristband are made from 16.18 inches of fabric and 8.63 inches of fabric.

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

Let the total ounces of ingredients in the cake be = 44 ounces

The ratio of flour to sugar is = 6 : 5

So , the amount of flour in 44 ounces = 6x

The amount of sugar in 44 ounces = 5x

And , the equation is

6x + 5x = 44

On simplifying the equation , we get

11x = 44

Divide by 11 on both sides , we get

x = 4

So , the total amount of sugar in 44 ounces of ingredients = 5x

Substitute the value for x = 4 , we get

Total amount of sugar in 44 ounces of ingredients = 20 ounces

And ,

Let the total ounces of ingredients in the new cake be = 91 ounces

The ratio of flour to sugar is = 7 : 6

So , the amount of flour in 91 ounces = 7y

The amount of sugar in 91 ounces = 6y

And , the equation is

7y + 6y = 91

On simplifying the equation , we get

13y = 91

Divide by 13 on both sides , we get

y = 7

So , the total amount of sugar in 91 ounces of ingredients = 6y

Substitute the value for y = 7 , we get

Total amount of sugar in 91 ounces of ingredients = 42 ounces

Therefore , the extra ounces of sugar the baker added to the new cake is =

Total amount of sugar in 91 ounces of ingredients - Total amount of sugar in 44 ounces of ingredients

The extra ounces of sugar the baker added to the new cake is = 42 - 20

Extra ounces of sugar the baker added to the new cake is = 22 ounces

Hence ,

The amount of ounces of sugar she added to the new cake is 22 ounces

It will take about 16.7 years to reach $15500.

The percentage that a lender adds to the amount of money lent to them is called an interest rate.

Given that, the initial deposited amount is P = $15000, the interest rate is r= 0.2% annually, and the final amount is $15500.

The interest earned is calculated by subtracting the initial amount from the final amount:

15500-15000

=500

Therefore, the interest earned is $500.

Now, the formula for the simple interest is:

interest = P × r × t

Substitute the known values:

500 = 15000 × 0.2% × t

500 = 15000 × 0.2/100 ×t

500 = 30t

t = 500/30

t = 16.7

Hence, It will take about 16.7 years to reach $15500.

Step-by-step explanation:

to find the first 3 terms, substitute n = 1, 2, 3 into the nth term rule

n = 1 : 1² + 2(1) = 1 + 2 = 3

n = 2 : 2² + 2(2) = 4 + 4 = 8

The expression x^2 + 22x + c becomes a perfect square trinomial if the value of c is 121, so the correct option is A.

A perfect square trinomial is written as:

(a + b)^2 = a^2 + 2ab + b^2

Here we have the expression:

x^2 + 22x + c

We can rewrite the second term in such a way that we get:

x^2 + 2*11*x + c

comparing this with the form of the general perfect square trinomial we can see that:

a = x

b = 11

Then the value of c must be 11^2 = 121

Then we have:

x^2 + 2*11*x + 121 = (x + 11)^2

The correct option is A.

The last digit of a₃₅ is 8 when each phrase (beginning with the third term) in the sequence $$1,2,2,4,8,32,256 is the product of the two terms that came before it.

Given that,

Each phrase (beginning with the third term) in the sequence $$1,2,2,4,8,32,256 is the product of the two terms that came before it. For instance, the seventh term, which is the sum of the fifth ($8) and sixth ($32) terms, is $256. Though the numbers very rapidly become large, this series can go on indefinitely! In terms of the number of particles in the observable universe, the $14 term, for instance, is close to some estimations.

We have to find what is the final digit of the sequence's $35 term.

We know that,

Remember the Fibonacci sequence, which goes 1, 1, 2, 3, 5, 8, 13, 21..., where each word is the total of the one before it. Continuing the above pattern, if Fn is the n-th Fibonacci number, we would arrive at

aₙ=a₂ˣₙ₋₁a₁ˣₙ₋₂=2ˣₙ₋₁

A periodic series of residues mod 10 is left behind by the sequence of positive powers of 2:

2⁴≡16 (mod 10)

2⁵≡32 (mod 10)

2⁶≡64 (mod 10)

And so forth; this series of residues has a 4-year period.

The taken mod 4 period is 6:

34≡4 (mod 6)

F₃₄≡3 (mod6)

2³=8

So, the last digit of a₃₅ is 8.

Therefore, the last digit of a₃₅ is 8 when each phrase (beginning with the third term) in the sequence $$1,2,2,4,8,32,256 is the product of the two terms that came before it.

On the other hand, weight is a measurement of how much gravity pulls an item downward. The mass of the thing has an impact on this force; the heavier the object, the stronger gravity's pull is. The force of gravity acting on a body is the most typical definition of weight given in introductory physics textbooks.
