The expression of the side length is 6y - 5

The complete question is added as an attachment

From the question, we have the following parameters that can be used in our computation:

Perimeter = 48y - 40

Number of sides = 8

The side length s can be calculated as

s =(48y - 40)/8

Evaluate the quotient

s = 6y - 5

Hence, the side length expression is 6y - 5

Answer:

Below

Step-by-step explanation:

The equation to use for CONTINUOUS compounding is :

FV = PV e^(it)

18532.08 = 8327 * e^( i*10)        where i is the interest in decimal form

18532.08/8327  = e^(10i)

2.225541 = e^(10i)             now take natural log  (ln) of both sides to get

.8000 = 10i

i = .08     or 8% interest

Answer: Must be 11 hats

Step-by-step explanation:

Each hats costs $5, and you have $57. So call the greatest amount of hats you can buy is x, we have: 5x=57 => x=57:5=11.4

The amount of hats can't be 11.4 right? The greatest amount of hats is 11.

Answer:

\(\bold{\boxed{\Huge \bold{\boxed{\text{11 hats}}}}}\)

Step-by-step explanation:

To find the greatest amount of hats that can be bought with $57, we need to divide the total amount of money by the cost of each hat. This will give us the maximum number of hats that we can buy.

Step 1: Divide the total amount of money by the cost of each hat.

\(\frac{57}{5} = 11.4\)

Since we cannot buy 0.4 of a hat:

The greatest amount of hats that can be bought with $57 is 11 hats.

Answer:

500

Step-by-step explanation:

To find range, you subtract the lowest value from the greatest value.

First you have to put the vaulues in order from least to greatest

4 things can be selected from a total of 9 without replacement in 126 times without replacement.

Combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of selection does not matter.

How to determine this

To calculate the combination without replacement

nCr = n!/r!(n-r)!

9C4= 9!/4!(9-4)!

= 9!/4!(5!)

= 9*8*7*6*5*4*3*2*1/4*3*2*1*5*4*3*2*1

= 362880/24*120

= 362880/2880

= 126

Therefore, it can be combined in 126 times

Answer:

8

Step-by-step explanation:

let x be the number , then

\(\frac{3}{4}\) x = 27 ( multiply both sides by 4 to clear the fraction )

3x = 108 ( divide both sides by 3 )

x = 36

the number is 36, so

\(\frac{2}{9}\) × 36 = 2 × 4 = 8

The two ninths of the number is 8

We know that Three quarters of a number is  \(\frac{3}{4}\)  times of a number

Hence we will assume the number x ,

                     \(\frac{3}{4} of x = 27\)

                     \(x = 27 X \frac{4}{3}\)

                       \(x = 36\)

Now as we know the number is 36

Therefore , the two ninths of the number assumed as y

We will multiply the number 36 by 2 and then divide by 9

Hence,

                           \(y = 36 X \frac{2}{9}\)

                               \(y = 8\)

Thus, the two ninths of the number 36  is 8

Answer:

Correct answer is 28

Step-by-step explanation:

The solution to the equation is 8.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

x - 3 + 1 = 6

Solve for x.

x - 2 = 6

x = 6 + 2

x = 8

We can cross-check.

x - 3 + 1 = 6

8 - 3 + 1 = 6

The ordered triple representing \(3u - 2v\) is \((13, -8, 5)\).

To find an ordered triple representing \(3u - 2v\),

where \(u = (5, -2, 3)\) and \(v = (1, 1, 2)\),

we can perform the following operations:

\(3u = 3(5, -2, 3)\)

\(3u = (15, -6, 9)\)

\(2v = 2(1, 1, 2)\)

\(2v = (2, 2, 4)\)

Now, subtracting 2v from 3u gives:

\(3u - 2v = (15, -6, 9) - (2, 2, 4)\)

\(3u - 2v = (15-2, -6-2, 9-4)\)

\(3u - 2v = (13, -8, 5)\)

Therefore, the ordered triple representing 3u - 2v is (13, -8, 5).

Step-by-step explanation:

it easy Add them all up and then you get 47/16 then divide them and convert it to mixed number and then you get 2 15/16

Answer:

2 15/16

Step-by-step explanation:

We need to make sure all fractions have the same denominator.

The LCM (least common denominator) is 16.

Now we have to multiply each nunber except 2 1/16 to get a numerator of 16.

1/2: 1x8= 8, 2x8= 16→ 8/16

3/8: 3x2= 6, 8x2= 16→ 6/16

Now every add everything all up.

8/16 + 6/16 + 2 1/16 = 2 15/16

2 15/16 is our answer.

Answer:

Step-by-step explanation:

Answer:

3/10

Step-by-step explanation:

let n(B)=students who have a brother

n(S)= students who have a sister

n(U)=n(B)+n(S)+n(BUS)'-n(BnS)

30=12+25+2-n(BnS)

30=39-n(BnS)

n(BnS)=39-30=9

So 9 students have a brother and a sister

Probability=9/30=3/10

The probability that a student who has a brother also has a sister will be 0.30.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

In a class of 30 students, 12 have a brother and 25 have a sister. There are 2 students who do not have any siblings.

The number of students who have both brothers and sisters. Then we have

25 - x + 12 - x + x + 2 = 30

x = 25 + 12 + 2 - 30

x = 9

Then the probability that a student who has a brother also has a sister will be given as,

P = 9 / 30

P = 0.30

The probability that a student who has a brother also has a sister will be 0.30.

d. The average amount of weight loss is greater than 2.5 pounds.

Step-by-step explanation:

After running a mile a day over a period of two weeks, the average amount of weight loss is 2.5 pounds.

At the null hypothesis, we test if this mean is of 2.5, that is:

\(H_0: \mu = 2.5\)

A dietitian, who publishes health articles in a newspaper, states their new diet program helps with additional weight loss.

With the additional weight loss, the dietitian claims that the mean is more than the value presented at the null hypothesis, that is, more than 2.5, and thus, the correct answer is:

\(H_1: \mu > 2.5\)

And thus, the correct option is given by option d.
