Total money with Kadeem  = $680

Money spent by him on a new bicycle = $470.65

Money left with him after buying a new bicycle = 680 - 470.65 = 209.35

Money spent by him on 2 bicycle reflectors = 7.87*2 = $15.74

Money left with him after buying reflectors = 209.35 - 15.74 = $193.61

Money spent by him on bike gloves = $15.18

Money left with him after buying biking outfits: 193.61 - 15.18 = $178.43

Cost of each outfit = $50.98

Let the number of outfits Kadeem can buy be x, therefore formulating the equation we get:

50.98x< = 178.43

x< = 3.5

So, Kadeem can buy 3 outfits while staying within budget

P = 2(l + w), where

Find the value of l:

Answer:

L = 89 cm

Step-by-step explanation:

Formula we use,

→ P = 2(L + W)

Then the value of its length is,

→ P = 2(L + W)

→ 324 = 2(L + 73)

→ 324 = 2L + 146

→ 2L = 324 - 146

→ L = 178/2

→ [ L = 89 cm ]

Hence, the length is 89 cm.

We get the equation in terms of n as n = s / 4 - v.

Equation:

An equation is an expression with an equal sign.

For example:

3 x + 4 y = 5

2 x + 5 y = 9 etc.

We are given an equation:

s = 4 n + 4 v

We have to solve this for n.

First we will subtract 4 v from both sides:

s - 4 v = 4 n + 4 v - 4 v

s - 4 v = 4 n

4 n = s - 4 v

Now divide both the sides by 4:

4 n / 4 = (s - 4 v) / 4

n = s / 4 - v

Therefore, we get the equation in terms of n as n = s / 4 - v.

First of all we know about the Estimation.

What is the Estimation?

To estimate the result of multiplication (product), round the numbers to some close numbers that can easily multiply . One method of estimation is to round all factors to the biggest digit (place value) they have.

General rule for rounding:

1 ) If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

2 ) If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.

So the last digit of number is 44 which is less then 50 so the number is down to its 10's.

thats the reason why when we estimate the product of 416x9 =3,744 is 3,600.

The probability that both of the boxes one would select had the decoder ring is 9.9%.

Given, the store manger gives the surety that 19 out of 59 boxes on the shelf have the secret decoder ring.

The boxes on the shelf which have a different gift inside is = 40 boxes.

If one randomly selects two boxes from the shelf to purchase, the probability that both of them have the secret decoder ring = ?

You can imagine that someone used invisible link to label each box with a number, and knows that boxes number 1 through 19 have decoder rings, while boxes number 20 through 59 have other gifts.

There are 59×58/2

= 3422/2

= 1711 possible sets of two boxes that one could select, but there are only 19 × 19/2

= 342/2

= 171 possible sets of two boxes with decoder rings.

The fraction of possible pairs of boxes where both boxes have the secret decoder ring is:

= 171/1711

= 0.099 = 9.9%

Hence there is 9.9% probability that both of the boxes one might select had a decoder ring.

The simplified form of the expression (( (-2 + h)³ + 8 ) / h) is h² - 6h + 12

Given the expression in question;

( (-2 + h)³ + 8 ) / h

First, we simplify the numerator.

Lets rewrite 8 as 2³

(-2 + h)³ + 2³

Now, we can use the sum of cubes formula to factorize since both terms are perfect cubes.

a³ + b³ = ( a + b )( a² - ab + b² )

(-2 + h)³ + 2³ = ( -2 + h + 2 )( (-2 + h)² - (-2 + h)2 + 2² )

(-2 + h)³ + 2³ = h( (-2 + h)² + 4 - 2h + 4 )

(-2 + h)³ + 2³ = h( (-2 + h)²- 2h + 8 )

(-2 + h)³ + 2³ = h( (h² - 4h + 4 )- 2h + 8 )

(-2 + h)³ + 2³ = h( h² - 4h + 4 - 2h + 8 )

(-2 + h)³ + 2³ = h( h² - 6h + 12 )

Now bring back the denominator.

( h( h² - 6h + 12 ) ) / h

Cancel the common factors h

h² - 6h + 12

Therefore, the simplified form of the expression (( (-2 + h)³ + 8 ) / h) is h² - 6h + 12

The sale price before taxes and after discount is $1,430.

Given that A couch with a list price of $2200 will be discounted 35 % at the time of purchase and asked to find the sale price before taxes.

The original cost of the couch=$2200

The discount percentage=35 %

I.e. 35 % of $2200 is $770

The discount given to the customer will be 35% i.e. $770

⇒The selling price will be $770 less than the original cost price.

As a result, the selling price will be =$2200-$770

Answer:

  8.  HI = 25 cm

  9.  HJ = 27.5 cm

  10.  IK = 5.5 cm

Step-by-step explanation:

Given segments JK=3 cm and IJ=2.5 cm of 30.5 cm length HK having points H, I, J, K in sequence, you want to find missing segment lengths.

The segment sum theorem tells you the length of a line segment is the sum of the lengths that make it up. That means ...

  HI +IJ +JK = HK

This lets you find the lengths of the various segments without concerning yourself with the value of x.

Using the given lengths in the above sum, we have ...

  HI +2.5 +3 = 30.5

  HI = 30.5 -5.5 = 25

The length of HI is 25 cm.

The overall length is the sum of its parts:

  HI +IJ = HJ

  25 +2.5 = 27.5 = HJ

The length of HJ is 27.5 cm.

The overall length is the sum of its parts:

  IJ +JK = IK

  2.5 +3 = 5.5 = IK

The length of IK is 5.5 cm.

Additional comment

In case you actually want to find x, you can find it from ...

  HI = 3x +4

  25 = 3x +4

  21 = 3x . . . . . . subtract 4

  7 = x . . . . . . . divide by 3.

In this set of problems, the only use of x is to find the value of 3x+4, which you have already seen is 25.

What is the Fibonacci sequence?

The Fibonacci sequence is a set of integers (the Fibonacci numbers) that starts with a zero, followed by a one, then by another one, and then by a series of steadily increasing numbers. The sequence follows the rule that each number is equal to the sum of the preceding two numbers.

The Fibonacci sequence begins with the following 14 integers:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233 ...

Each number, starting with the third, adheres to the prescribed formula. For example, the seventh number, 8, is preceded by 3 and 5, which add up to 8.

The sequence can theoretically continue to infinity, using the same formula for each new number. Some resources show the Fibonacci sequence starting with a one instead of a zero, but this is fairly uncommon.

Example 1: Starting with 0 and 1, write the first 5 Fibonacci numbers.

Solution: The formula for the Fibonacci sequence is Fn= Fn-1+Fn-2

The first and second terms are 0 and 1, respectively.

F0 = 0 and F1 = 1.

F2 = F0 + F1 = 0+1 = 1 is the third term.

F3 = F2+F1 = 1 + 1 = 2 is the fourth term.

F4 = F3+F2 = 1+2 = 3 is the fifth term.

The Fibonacci sequence’s first five terms are 0,1,1,2,3.

Example 2: Find the Fibonacci series’ next term: 0, 1, 1, 2, 3, 5…

Solution: The preceding two Fibonacci terms are the next term in the series.

As a result, the word that must be used is – 3 + 5 = 8

Example 3: What is the significance of Fibonacci numbers?

Solution: In financial statement analysis, Fibonacci numbers are pretty helpful. In addition, the Fibonacci number series may be utilized to provide valuable proportions or ratios for business people.

Example 4: Find the 12th term of the Fibonacci sequence if the 10th and 11th terms are 34 and 55, respectively.

Solution: Using the Fibonacci Sequence recursive formula, we can say that the 12th term is the sum of the 10th term and the 11th term

12th term = 10th term + 11th term

= 34 + 55

= 89

The 12th term of the Fibonacci sequence is 89.

Example 5: The 14th term in the sequence is 377. Find the next term.

Solution: We know that the 15th term = the 14th term × the golden ratio.

F15 = 377 × 1.618034

≈ 609.99 = 610

The 15th term in the Fibonacci sequence is 610.

Answer: 59.5

Step-by-step explanation: 29 3/4 times 2

I think

The function f(x) = |x|, after shifting it down by 4 units and right by 3 units can be written as -

(y - 4) - |x - 3| = 0

The modulus function can be written as follows -

|x| =  x  [for x ≥ 0]  

|x| = - x [for x < 0]

Given that a function f(x) = |x| which is shifted down by 4 units and right by 3 units. Therefore, we can write -

y = f(x) = |x|

Change in y - coordinate = y + 4.

Change in x - coordinate = x - 3.

We will plot the graph of h(x) after the doing the given changes in the coordinates.

Now, we have -

y = |x|

y - |x| = 0

Change in y - coordinate can be written as -

(y + 4) - |x| = 0

Change in x - coordinate can be written as -

(y - 4) - |x - 3| = 0

Now, the graph of both f(x) and and h(x) is attached at the end.

Therefore, the function f(x) = |x|, after shifting it down by 4 units and right by 3 units can be written as -

(y - 4) - |x - 3| = 0
