Convert these unlike fractions to equivalent like fractions and add them. You must use the LCD to get the answer correct. If possible, reduce the final sum.

Answers

Your final answer would be 2/3.

The LCD would be 12.

You would have to multiply both the top and bottom of 1/4 to get the denominator to 12.

To do this, you multiply it both the numerator and denominator by 3.

This would leave you with 3/12.

The second fraction already has a denominator of 12 so we will just leave it as is.

Then you add.

3/12 + 5/12

This would give you

8/12

Then you simplify it or "reduce it" by dividing both the top and bottom by 4 to get your final answer.

2/3

The simplest form expression for the addition of the fractions given using the lowest common multiple of of the denominator is 2/3.

Given the fractions :

1/4 + 5/12

The lowest common multiple of the denominator ;

Lowest common multiple of 4 and 12 = 12

1/4 + 5/12 = (3 + 5) / 12

1/4 + 5/12 = 8/12

Expressing in simplest form :

8/12 = 2/3

Therefore, the simplest form expression of the addition is 2/3

two consecutive even integers have a sum of 346. Find the smailler of these two numbers

Answers

Assume two numbers are n and n+2

Then n+ n+2 = 346 -> 2n = 344 -> n= 172

So the smaller one is 172, another one is 174

Answer:

Smallest number = 172

Step-by-step explanation:

Two consecutive even integers have a sum of 346.

Let x be the smallest number.

We have other number = x + 2

We also have

x + x + 2 = 346

2x + 2 = 346

2 x = 344

x = 172

Smallest number = 172, Other number = 172 + 2 = 174

Smallest number = 172

Answers

slope = 2/-2 = -1

if x = -5, y = 3

equation
y - 3 = -1(x +5)
y - 3 = - (x + 5)

answer

y – 3 = –(x + 5)

Answer: The correct option is (B) [tex]y-3=-(x+5).[/tex]

Step-by-step explanation: We are given to match the graph shown with the correct equation.

From the graph, we note that

(-5, 3) and (0, -2) are two points that lie on the line graph.

So, the slope of the given graph is

[tex]m=\dfrac{-2-3}{0-(-5)}\\\\\\\Rightarrow m=\dfrac{-5}{5}\\\\\Rightarrow m=-1.[/tex]

Since the point (-5, 3) lies on the line, so its equation in point-slope form will be

[tex]y-3=m(x-(-5))\\\\\Rightarrow y-3=-(x+5).[/tex]

Thus, option (B) is CORRECT.

Dominick is planning to take a vacation to either Orlando or Tampa Bay. He wants to go to the city that is warmer, on average. The box plot below shows the temperatures from the previous year during the time that Dominick will take his vacation: box plot labeled Orlando with min at 64.5, Q1 at 65.5, median at 67.5, Q3 at 71.5, max at 72.5. Box plot labeled Tampa Bay with min at 60, Q1 at 63.5, median at 66.25, Q3 at 72.5, max at 74 Which city should Dominick visit, and why?

Answers

Orlando

Median = 67.5
Interquartile Range = Q₃ - Q₁ = 71.5 - 65.5 = 6
Range = Max Value - Min Value = 72.5 - 64.5 = 8

Tampa Bay

Median = 62.25
Interquartile Range = Q₃ - Q₁ = 72.5 - 63.5 = 9
Range = Max Value - Min Value = 74 - 60 = 14

From the three values that we can read from the box plots, Orlando has the higher median, lower interquartile range and lower range.

Lower interquartile range and range indicates a more consistent data, so we can say that Orlando has more consistent warmer temperature than Tampa Bay.

Dominick should visit Orlando

Answer:

He should visit Orlando. The median is higher and the range is smaller, so the temperature is higher on average.

Jackie's total number of coins is 204.. She has twice as many quarters as nickels and three times as many dimes as nickels.. How many of each coin does she have ??

Thank you so much :)

Answers

Call x the number of nickles that she has.

Then the number of quarters is twice x = 2x

And the number of dimes is three times x = 3x.

So, the total number of coins is x + 2x + 3x = 240

=> 6x = 240

=> x = 240 / 6

=> x = 40

=> Number of nickels = x = 40

Number of quarters = 2x = 80

Number of dimes = 3x = 120

Verification: 40 + 80 + 120 = 240

Answer: nickles 40, quarters 80, and dimes 120.

68.32 divided by 2.8

Answers

Answer:

24.4

Step-by-step explanation:

We are asked to divide 68.32 by 2.8.

First of all, we will write our given problem as a division problem.

[tex]\frac{68.32}{2.8}[/tex]

We can see that our numerator has two digits after decimal and denominator has one digit after decimal, so we will multiply numerator and denominator by 100 as:

[tex]\frac{68.32\times 100}{2.8\times 100}[/tex]

[tex]\frac{6832}{280}=24.4[/tex]

Therefore, the quotient of our given problem is 24.4.

24.4

Further explanation

We will determine the quotient of 68.32 against 2.8.

Notes:

The division process is the arithmetic operation of the distribution of equal parts of a number. The division is the opposite of the multiplication process.

24.4 __

2.8 ) 6 8 . 3 2

- 6 7 . 2 [tex]\downarrow[/tex]

1 . 1 2

- 1 . 1 2

Please see the attached picture.

The terminology of the division operation associated with the above scheme is as follows:

[tex]\boxed{ \ 68.32 \rightarrow the \ dividend \ }[/tex][tex]\boxed{ \ 2.8 \rightarrow the \ divisor \ }[/tex][tex]\boxed{ \ 24.4 \rightarrow the \ quotient \ }[/tex] [tex]\boxed{ \ 0 \rightarrow the \ remainder \ }[/tex]

Therefore, 68.32 divided by 2.8 is divisible because the remainder is zero.

Thus, the quotient of 68.32 divided by 2.8 is 24.4.

- - - - - - - - - -

Alternative Strategy

[tex]\boxed{ \ 68.32 = 56 + 12.32 \ }[/tex]

[tex]\boxed{ \ 68.32 \div 2.8 = (56 \div 2.8) + (12.32 \div 2.8) \ }[/tex]

[tex]\boxed{ \ 68.32 \div 2.8 = 20 + 4.4 \ }[/tex]

Bryan is observing the velocity of a cyclist at different times. After four hours, the velocity of the cyclist is 15 km/h. After seven hours, the velocity of the cyclist is 12 km/h.

Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist at different times. Show your work and define the variables used. (5 points)

Part B: How can you graph the equations obtained in Part A for the first 12 hours? (5 points)

Answers

Part A.

What we can do to solve this problem is to assume that the acceleration of Bryan is constant so that the velocity function is linear. The standard form of a linear function is in the form:

y = m x + b

or in this case:

v = m t + b

where v is velocity and t is time, b is the y –intercept of the equation

The slope m can be calculated by:

m = (v2 – v1) / (t2 – t1)

m = (12 – 15) / (7 – 4)

m = -1

Since slope is negative therefore this means the cyclist are constantly decelerating. The equation then becomes:

v = - t + b

Now finding for b by plugging in any data pair:

15 = - (4) + b

b = 19

So the complete equation is:

v = - t + 19

This means that the initial velocity of the cyclists at t = 0 is 19 km / h.

Part B. What we can do to graph the equation is to calculate for the values of v from t = 0 to 12, then plot all these values in the Cartesian plane then connect the dots.

Angle of elevation

The angle of elevation is the angle at which the object is viewed from below.

If tree casts a shadow that is 18 feet in length at the angle of 28 degrees, the height is calculated as:

sin theta = opposite/hypotenuse
