Answer:

9/5 + 9/4 = 81/20

= 4 1/20

= 4.05

Step-by-step explanation:

81/20 is the smallest it gets as a fraction I believe

and A. should be 5/4 if i'm not mistaken

Answer:

a) 1 1/4 or b) 4 1/20

Step-by-step explanation:

a) This one is the easier of the two. 7/8+3/8= 10/8 ---» 1 2/8 and 2/8 is 1/4. So 1 1/4.

b) This one is a bit more tricky. You need to find a common denominator between the two, in this case we can use 20.

9/5 ---» 36/20 and 9/4 ----» 45/20.

Do some adding and you get 81/20 ---» 4 1/20.

Answer:

½ i + ¾ j = (½ , ¾)

Step-by-step explanation:

The gradient of a scalar function is a vector. Which is calculated as written in the image.

Step-by-step explanation:

x³ - y³ = (x - y)³ + 3x²y - 3xy²

28 = (2)³ + 3xy(x - y)

28 = 8 + 3xy(2)

28 - 8 = 6xy

20 = 6xy → xy = 20/6 = 10/3

(x - y)² = 2²

x² - 2xy + y² = 4

x² - 2(10/3) + y² = 4

x² + y² = 4 + 20/3 = 32/3

x² + xy + y² = 32/3 + 10/3 = 42/3 = 14

Answer:

f(x) = x2 (x-a)5 (x-b)

Step-by-step explanation:

because if you graph the plots correctly you should get this

The equation of the graph of the polynomials is f ( x ) = x² ( x - a )⁵ ( x - b )

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x² ( x - a )⁵ ( x - b )

From the graph of the polynomial , we can see that

The critical points of the function f(x) = x² ( x - a )⁵ ( x - b ) are x = 0, x = a, x = b, and x = (7a + 5b)/3

Hence , the function is f ( x ) = x² ( x - a )⁵ ( x - b )

Answer:  slope of a line perpendicular is [tex]\frac{5}{7}[/tex]; slope of a line parallel to this line is [tex]-\frac{7}{5}[/tex].

Step-by-step explanation:

Rewrite the line in y = mx + b form, where m is slope and b is y-intercept.

7x + 5y = -2

       5y = -7x -2

         y = [tex]-\frac{7}{5}[/tex]x - [tex]\frac{2}{5}[/tex]

The product of two slope of perpendicular line is -1.

Let x be the other line that perpendicular line with the line 7x + 5y = -2.

（[tex]-\frac{7}{5}[/tex])x = -1

        x = [tex]\frac{5}{7}[/tex]

The slope of a line parallel to this line is the same, which is [tex]-\frac{7}{5}[/tex].

Answer:

So I don’t know if this is right cause yeha but I think that m=5

Step-by-step explanation:

we can substitute different numbers starting with one

Or this is the way I did we can do 10+5 which = 15

So that means 15/3=5

So m=5

also I don’t know if this is correct….:/

Answer:

m=5

Step-by-step explanation:

step 1:letters to the left side of the =, numbers to the right (If there are numbers attached to the letter, keep it on the left) if a number is being taken to the right, change the sign to the opposite of what it was

3m= 5+10

step 2: add the numbers on the right

3m=15

step 2: divide both sides by 3 to get m alone

m=5

Given that the length of the table is twice the width which is 1.25 m. and

the difference in the parallel side is 1 m., the area of the table is 2.5 m².

The possible table dimensions are;

Width of the table = 1.25 m

Width of the table = The height of the trapezoid

The difference in length between the parallel sides = 2 × 0.5 m = 1 m

Longest side of the table is a parallel side of the trapezoid

Given;

Length of the longest side of the table = 2 × The width

Which gives;

Length of the longest side of the table = 2 × 1.25 m = 2.5 m

Length of other parallel side = 2.5 m - 1 m = 1.5 m

[tex]Area \ of \ a \ trapezoid = \mathbf{\dfrac{Sum \ of \ length \ of \ parallel \ sides}{2} \times Height}[/tex]

Which gives;

[tex]\mathbf{Area \ of}\ the \ \mathbf{table} = \dfrac{2.5 + 1.5}{2} \times 1.25 = 2.5[/tex]

The area of the = 2.5 m²

— length of the longest side of the table = 2 × width which gives you 'length of the longest side of the table = 2 × 1.25 meters' which equals 2.5 meters. to find length of other parallel side use the equation 2.5 meters minus 1 meter, which is 1.5 meters. lastly to find the area, do  [tex]\frac{sum of length of parallel sides}{2}[/tex] multiplied by the height, which afer you fill it out turns into [tex]\frac{2.5+1.5}{2} *1.25[/tex] , which equals 2.5 meters. so the area is 2.5 meters squared.

Explanation:

Each of the five bags contain x pencils, where x is a placeholder for a positive whole number.

This means Tyler starts off with 5x pencils

He then adds 3 pencils per bag, so 3*5 = 15 extra pencils, to get the expression 5x+15. We're told the new grand total is 20 pencils.

Therefore, the equation for this story problem is 5x+15 = 20

The reason for the multiplication is because we have the same number of pencils per bag. So we're adding multiple groups together, or using multiplication to do a shortcut.

eg: instead of 5+5+5 = 15 we can do 5*3 = 15

Answer:

X + 5 = 27 or 27 - 5 = X

the answer is $22

Step-by-step explanation:

Answer:

x-5=27 or 27=x-5 or x=27+5

Step-by-step explanation:

let x be the total amount of money Penny has.

after she deducts 5 dollars to pay for her bunny she is left with 27

    therefore

x-5=27 (which is the same as representing it in any other way shown above)

if they ask for X, then solve your equation

x=27+5

x=$32

Answer:

Therefore, x is 1 and 2.

Step-by-step explanation:

As you plot both equations on the same graph, you will get something like this, shown in the graph.

Then, you have to find the x solutions where they intersect.

So, both equations intersect at x = 1 and 2.

Answer: 200%

Step-by-step explanation: Seeing as 1:1 is a 100% and we all understand that just add 100% more for every number on the left if the other side is = to 1

The equation for the first tank will be 175 - 25h and the equation for the second tank is 200 - 25h.

From the information given, the first tank holds 175 gallons of water and the second tank holds 200 gallons of water while the hoses that she uses drain the tanks at a rate of 25 gallons of water per hour.

Therefore, the equation for the first tank will be:

= 175 - (25 × h)

= 175 - 25h

The equation for the second tank will be:

= 200 - (25 × h)

= 200 - 25h

The quantity in the first tank after three hours will be:

= 175 - 25h

= 175 - (25 × 3)

= 175 - 75

= 100 gallons.

The quantity in the second tank after three hours will be:

= 200 - 25h

= 200 - (25 × 3)

= 200 - 75

= 125 gallons.

Explanation:

If you lose 9% of a substance, then you keep the remaining 91% because 100% - 9% = 91%. Or you can think of it as 91% + 9% = 100%

Then we convert 91% to decimal form to get 0.91

-----------

Or you can do the steps like this:

9% = 0.09

1 - 0.09 = 0.91

Answer:

6m

Step-by-step explanation:

To find the original length you must take away the add-ons. To do so we know that they added 7 and A= l*l (or l squared). They added the 7 to the length so multiply 7*7 (49) subtract your answer from 169 (120) and that's your new area. To find the original length divide by 4 (I believe) and get 30m2
