Answer:

-3mn^3 and -5mn^3

Step-by-step explanation:

had it correct on my test - PLATO

Marcus  has to add -3mn^3 and -5mn^3 to complete the polynomial.

Marcus is rewriting a polynomial by combining like terms

Polynomial equation is equation of independent variables.

Here, questions seems to be incomplete.
In polynomial, it can be of maximum endless number of term or minimum 1 term. Marcus can add any number or repeat any number. And if he revised the old number than the number could be -3mn^3 and -5mn^3.

Thus, Marcus  has to add -3mn^3 and -5mn^3 to complete the polynomial.

Answer: y=8 m=5

Step-by-step explanation:

Answer:

1. 3.125

2. 4.5

Step-by-step explanation:

1. Since the figures are similar, the number you divide from one triangle to the other is the same, no matter the side length. 5(x) = 8 so 5/x = y. If x = 1.6, then y equals 3.125.

2. The same thing here. 4/x = 3 and 6/x = m. In the first equation x would be 1 1 1/3. 6/ 1 1/3 is the same as 6 x 3/4 which is 18/4 or 4.5.

Step-by-step explanation:

Given:

A right rectangular prism is packed with cubes of side length [tex]\dfrac{1}{5}[/tex] inch.

Prism is packed with 15 cubes along the length, 6 cubes along the width, and 5 cubes along the height.

To find:

The volume of the prism

Solution:

Side length of each cube [tex]=\dfrac{1}{5}[/tex] inch.

15 cubes along the length, so length of prism is

[tex]l=15\times \dfrac{1}{5}=3\text{ inches}[/tex]

6 cubes along the width, so width of prism is

[tex]b=6\times \dfrac{1}{5}=\dfrac{6}{5}\text{ inches}[/tex]

5 cubes along the height, so height of prism is

[tex]h=5\times \dfrac{1}{5}=1\text{ inch}[/tex]

Now,

Volume of rectangular prism is

[tex]V=l\times b\times h[/tex]

[tex]V=3\times \dfrac{6}{5}\times 1[/tex]

[tex]V=\dfrac{18}{5}[/tex]

[tex]V=\dfrac{3\times 5+3}{5}[/tex]

[tex]V=3\dfrac{3}{5}\text{ cubic inches}[/tex]

Therefore, the correct option is B.

Answer:

x = 3.75 or [tex]3\frac{3}{4}[/tex]

Step-by-step explanation:

17 = -13 - 8x

add 13 to both sides

17 + 13 = -13 + 13 + 8x

30 = 8x

divide both sides by 8

30/8 = 8x /8

3.75 = x

There's no way to answer this question 100% accurately, because we don't know your teacher's grading scale, or how much tests and quizzes are weighted for your grade in the class. That being said, one test shouldn't bring your grade down too much. As the year goes on, and more assignments are put in the gradebook, it will even out. If you get a 100 percent on 3 tests, and a 60 percent on one test, it evens out to a 90 percent.

Answer:

The total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is [tex]\frac{1}{2}x+16=\frac{3}{4}x-1[/tex]

Step-by-step explanation:

Let x be the total number of burritos consumed

We are given that On Tuesday, Delainey ate 16 more than 1/2 the total number of burritos consumed

So, Number of burritos ate by Delainey on Tuesday=[tex]\frac{1}{2}x+16[/tex]

We are also given that  Louie ate 1 less than 3/4 of the total number of burritos consumed.

So, Number of burritos ate by Louie on Wednesday =[tex]\frac{3}{4}x-1[/tex]

We are given that The number of burritos Delainy ate on Tuesday is the same as the number of burritos Louie ate on Wednesday.

So, [tex]\frac{1}{2}x+16=\frac{3}{4}x-1\\1+16=\frac{3}{4}x-\frac{1}{2}x\\17=\frac{x}{4}\\68=x[/tex]

Hence  the total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is [tex]\frac{1}{2}x+16=\frac{3}{4}x-1[/tex]

The answer is Dun Dun Duuun 3 {x/4} - 1/2{x/10}

The expression equivalent to 70% of x is,

⇒ 3 (StartFraction x Over 4 EndFraction) minus one-half (StartFraction x Over 10 EndFraction)

⇒ 3 (x/4) - 1/2 (x/10)

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

The expression is,

⇒ 70% of x

Now, We an simplify the expression as;

⇒ 70% of x

⇒ 70/100 × x

⇒ 70x/100

⇒ 7x/10

By option 1;

⇒ 3 (x/4) - 1/2 (x/10)

⇒ 3x/4 - x/20

⇒ (60x - 4x) / 80

⇒ 56x / 80

⇒ 7x/10

Answer:

Donald trump is the president

Answer:

donald trump at the time but soon it will change

Step-by-step explanation:

You can find this by using the pythagorean theorem.

The Pythagorean Theorem states that the squares of the legs add up to the square of the hypotenuse.

The hypotenuse is the longest side, which is opposite the right angle.

The other 2 sides are the legs.

Here, the hypotenuse is BC which is 17.

AC is one leg. We are trying to find the other leg.

So you set up the equation AB^2+ 15^2 = 17^2.

This simplifies to AB^2 + 225 = 289.

AB^2 = 64.

AB = 8.

     n= 28/3 or 9.333333

4. -3+n+5=28

          n+2= 28

       n+2-2= 28-2

Answer:

Total amount spent [tex]=\$73.5[/tex]

If they decide to split the bill, amount paid by each of the person  [tex]=\$15.25[/tex]

Step-by-step explanation:

Cost of each movie ticket = $11

Cost of 5 tickets = 5(11)= 55

Cost of each packet of popcorns = $3.75

Cost of two packets of popcorns = $2(3.75) = $7.5

Cost of each soda = $2.75

Cost of five sodas = $5(2.75) = $13.75

Total number of persons (Rachel and four friends) = 5

Total amount spent [tex]=11(5)+2(3.75)+5(2.75)=55+7.5+13.75=\$76.25[/tex]

If they decide to split the bill, amount paid by each of the person = [tex]\frac{76.25}{5}=\$15.25[/tex]

Let's see what to do buddy...

_________________________________

[tex]x - 9y = 17[/tex]

Subtract the sides of the equation minus x

[tex] - 9y = 17 - x[/tex]

Divided the sides of the equation by -9

[tex] \frac{ - 9}{ - 9}y = \frac{17 - x}{ - 9} \\ \\ [/tex]

[tex]y = \frac{ - (17 - x)}{9} \\ [/tex]

[tex]y = \frac{x - 17}{9} \\ [/tex]

B.The weather pattern in City 2 is more consistent than the weather pattern in City 1

explanation:

Range and interquartile range (IQR) measures the spread of data. Range measure the overall spread and IQR measures spread in 50% of data.

Range is calculated by differencevof maximum and minimum value whereas IQR is calculated by difference of First quartile and third quartile.

Since, the range and IQR is less for City 2 as compared to City 1.

Thus ,weather pattern of City 2 is more consistent as compared to City 1.
