Step-by-step explanation

Answer:

width = 15 inches

length = 36 inches

Step-by-step explanation:

To solve you need to find the width...

width = w

length = 2w + 6

the perimeter is all the way around the area, so..

2w + 2(2w + 6) = 102

because there are 2 widths and 2 lengths in a perimeter.

Solve for w:

2w + 4w + 12 = 102

subtract 12 from both sides and combine like terms...

6w = 90

divide both sides by 6...

w = 15

the width = 15, and the length = 2(15) + 6 = 36

Answer:

in the number 16.344, the number 3 is in the tenths place

Step-by-step explanation:

Answer:

The codes are:

N,_,_,_

Where each _ represents a possible letter, out of 26.

And N is a number of two digits.

So in total we can think that we have 5 empty slots.

_,_,_,_,_

In the first slot we can put any digit between 0 and 9, so here we have 10 options.

In the second slot we can put any digit between 0 and 9, so here we have 10 options.

In the third slot we can put any letter, so here we have 26 options (and exactly the same for the fourth and fifth slots)

The total number of different combinations is equal to the product of the number of options for each slot.

C = 10*10*26*26*26 = 1,757,600

Now, if we want to have at least one nine, we can fix it in the first slot.

Then we have:

in the first slot we have only one option (the 9)

In the second slot we can put any digit between 0 and 9, so here we have 10 options.

In the third slot we can put any letter, so here we have 26 options (and exactly the same for the fourth and fifth slots)

The number of combinations is:

C = 1*10*26*26*26 = 175,760

But we also should consider the case where we fix the 9 in the second slot, so the actual number of combinations is twice the number above.

C = 2*175,760 = 351,520

The probability that the code does not contain the number 9.

Now in the first slot we have only 9 options, all the whole numbers between 0 and 8.

The same for the second slot, 9 options.

For the third, fourth and fifth slot is the same as before.

The total number of combinations is:

C = 9*9*26*26*26 = 1,423,656

Answer:

w = -1

Step-by-step explanation:

3(w + 14) = -2(1.5 - 6)

3w + 12   = -3 - (-12)

3w + 12 = 9

      -12   -12

3w = -3

w = -1

Yes, y = 6x + 5 is linear function.

Given that,
To explain does y = 6x+5 represent a function.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
y = 6x + 5, represents the line,
comparing it with the standard from the equation of the line,
y = mx + c
After comparing
m = = 6 and c = 5
And also for every value of independent variable x, there is a distinct value of dependent variable y.

Thus, Yes, y = 6x + 5 is linear function.

Step-by-step explanation:

In order to find another way to represent the fraction [tex]2 \frac{1}{4}[/tex], we need to find different ways to represent fractions as a whole. One way to write fractions are as decimals.

We know that 2 as a decimal is just 2. We can leave that be for now.

We also know that [tex]\frac{1}{4}[/tex] as a fraction will just be [tex]1 \div 4[/tex], which is 0.25. Therefore, combining 2 and 0.25 we get 2.25.

5 milk shakes

Step-by-step explanation:

From the above question, we know that for the recipe

1/3 cup of milk = 1 milk shake

15/8 cup of milk = y milk shakes

We cross Multiply

15/8 cup × 1 = 1/3cup × y

y = 15/8 cup × 1 /1/3cup

= 15/8 ÷ 1/3

= 15/8 × 3

= 45/8

= 5.625 of 5 5/8 cups of milk

Therefore, the maximum number of

milkshakes the server can make following the recipe porpotians is 5 milk shakes.

Answer:

x-(x+6)

Step-by-step explanation:

Answer:

Part A)

All real numbers between 0 and 3.4 (including 0 and 3.4).

Part B)

All real numbers between 5 and 50 (including 5 and 50).

Part C)

See below.

Step-by-step explanation:

We know that the rocket rose to a maximum of 50 feet and was in the air for 3.4 seconds. The rocket started at a height of 5 feet.

Part A)

The practical domain of a function is the domain with the context. Here, our domain is the number of seconds that had passed. Time can't be negative, so our domain must be greater than or equal to 0. Also, since we know that our rocket landed after 3.4 seconds, this means that our practical domain is all real numbers between 0 and 3.4 including 0 and 3.4.

Part B)

The practical range of a function is the range with the context. Here, our range is the height the rocket reaches. We know that the rocket started at a height of 5 feet, so our practical range should be greater than or equal to 5. We also know that the maximum height the rocket reached was 50 feet. So, our practical range is all real numbers between 5 and 50 including 5 and 50.

Part C)

The theoretical domain and range differs from the practical domain and range in that the theoretical counterparts don't consider the context. For the theoretical domain and range, we will analyze this as a normal quadratic. Since it's a quadratic, the theoretical domain is all real numbers. Since our maximum value is y=50, our theoretical range is all numbers less than or equal to 50.

However, this can't be used since negative time (e.g. height after -2 seconds) is inapplicable and negative height doesn't make sense in this context either (well, technically negative height can indicate that the rocket goes underground, but this is not mentioned here).

So, it is important to determine when to use practical domain/range and theoretical domain/range!

Commutative property

5

Step-by-step explanation:

The identity used in equation (-2) + 6 + 1 = 1 + 6 + (-2) is commutative property.

Given,

To Identify the property used in this equation:
(-2) + 6 + 1 = 1 + 6 + (-2)
commutative property

In mathematics, it deals with numbers of operations according to the statements.

Commutative property

The commutative property procedure applies to addition and multiplication. The addition procedure says that a + b = b + a and the multiplication procedure states that a x b = b x a. These procedures are used to define the notion that when adding or multiplying, values can “commute”, or resettle, and the outcome will not change.

Given equation,
(-2) + 6 + 1 = 1 + 6 + (-2)
Which shows the resettlement of -2, which does not affect the outcome of the equation. This is commutative property.

Thus, the identity used in equation (-2) + 6 + 1 = 1 + 6 + (-2) is commutative property.

Answer: B

Step-by-step explanation:

P(A and B) = P(A)*P(B|A)

P(A and B) = 0.8*0.31

P(A and B) = 0.248

The notation P(B|A) means "Probability of B given A". It's the same as "P(B) given event A has happened". It is conditional probability notation. The symbol between the A and B is a vertical line and not a letter.

Answer:

y  =  − 2 x  +  8

Step-by-step explanation:

Find the value of  b  using the formula for the equation of a line.

    Use the formula for the equation of a line to find  b .

    y = m x + b

    Substitute the value of  m  into the equation.

    y = ( − 2 ) ⋅ x + b

    Substitute the value of  x  into the equation.

    y = ( − 2 ) ⋅ ( − 3 ) + b

    Substitute the value of  y  into the equation.

    14 = ( − 2 ) ⋅ ( − 3 ) + b

    Find the value of  b .

    Rewrite the equation

    ( − 2 ) ⋅ ( − 3 ) + b = 14 .

    Multiply  − 2  by  − 3

    6 + b = 14

    Subtract  6  from both sides of the equation.

    b = 14 − 6

    Subtract  6  from  14 .

     b  =  8

Now that the values of  

m  (slope) and  b  (y-intercept) are known, substitute them into  y = m x + b  to find the equation of the line.

y = − 2 x + 8

Answer:

nei prossimi giorni, che si è svolto il convegno

Answer:

6 hours

Step-by-step explanation:

Total time it will take to complete the trip = Total time spent on riding + Time taken for lunch break.

Distance to be covered = 60 miles.

D = 60

Speed of riding = 15 miles per hour

S = 15

Thus time taken to cover a distance 60 miles by riding at a speed of 15 mph:

T=D/S=60/15

T= 4hours

They will spend 4 hours on riding and 2 hour of lunch break.

Hence total time taken to complete the trip = 4 + 2 = 6 hours.

It will take 6 hours to complete the trip.

The number of hours taken by riders to complete the trip is 6 hours.

Given that, distance = 60 mile, speed = 15 mph and lunch break = 2 hours.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Using speed formula Speed=Distance/Time

Here, 15 = 60/Time

⇒ Time = 60/15

= 4 hours

Total time taken in the trip is 4+2 = 6 hours

Hence, the number of hours taken by riders to complete the trip is 6 hours.
