For the polynomial f(x)=2x^3-9x^2+11x-20 as

Answer:

[tex]d=0.364\ g/cm^3[/tex]

Step-by-step explanation:

It is given that,

Mass of benzene, m = 0.1 L

Mass, m = 36.4 g

We know that, 1 L = 1000 cm³

0.1 L = 100 cm³

The density of an object is equal to its mass divided by its volume. So,

[tex]\rho=\dfrac{m}{V}\\\\=\dfrac{36.4\ g}{100\ cm^3}\\\\=0.364\ g/cm^3[/tex]

So, the density of benzene is [tex]0.364\ g/cm^3[/tex].

Answer:

1x=864,

2y=3

Step-by-step explanation:

y=6,x=?

if x is directly proportional to y^3 &if (when x=32, y is=2) we can understand that x=4y^3

1,x=4y^3

x=4(6^3)

x=4(216)

x=864

2,x=4y^3

108=4y^3

108/4=4y^3/4

27=y^3

√27=y

y=3

i think it is easy to understand,but if the answers are not clear you can ask me &i hope it helps you

Answer:

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Answer:

55 performances

Step-by-step explanation:

The first equation will be the total cost. The total cost has $88,000 already and then $5,900 is added with each performance. So the equation would be 88,000+5,900x because x will represent the number of performances.

y = 88,000 + 5,900x

The next equation will be how much the performances earn. If they earn $7,500 with each performance then the equation will be 7,500x, with x representing the number of performances

y = 7,500x

Now set the equations equal to each other and solve for x

7,500x = 88,000 + 5,900x

1,600x = 88,000

x = 55

They need to have 55 performances for the cost and the revenue to break even.

Step-by-step explanation:

Answer:

1/4 of the pizza is left

If Sam eats 1/4 of the pizza, we must subtract 1/4 from 1.

1 - 1/4 = 3/4.

Now, Since Joe eats 1/2 of the pizza, we subtract 2/4, since 1/2 = 2/4.

3/14 - 2/4 = 1/4.

Answer = 1/4

Step-by-step explanation:

first, expand the brackets

4a + 4a + 12a² + 8b + 4b - 4a²

then, collect like terms

8a + 8a² + 12b

then, rearrange

8a² + 8a + 12b

Answer:

11

Step-by-step explanation:

the square root of 129-8 will equal to 11

Answer:

y = 11

Step-by-step explanation:

You first have to insert the x value.

y equals the square root of 129 minus 8

Which would leave it to be the square root of 121 which is 11.

Answer:

832.5.

Step-by-step explanation:

sorry, but this cannot type fractions, so just take the answer.

Answer:

832.5

Step-by-step explanation:

To find the area of a trapezoid, you need to use the formula (a+b)/2 x h

a = 18 = base

b = 27 = base

h = 37 = height

18 + 27 = 45

45/2= 22.5

37 x 22.5 = 832.5

Answer:

Step-by-step explanation:

step one:

let the number of Blu-rays  be b and

DVDS be d,

step two:

given that Blu-rays cost $25.99each and

DVDS cost $15.99 each,

we can model the cost of the Blu-rays and DVDS, as

100=25.99b+15.99d

hence the expression for the number of Blu-rays and DVDS, is given as

100=25.99b+15.99d

Answer:

x=4

Step-by-step explanation:

First set the equation equal to 4:

-2x +12=4

Subtract 12 from both sides:

-2x +12=4

      -12  -12

-2x=-8

Then divide each side by -2 to isolate the x:

-2x/-2=-8/-2

x=4

Option C, y = 1/2 x -2 is the correct answer

35/40 ×100 is a numerical expression to describe the percentage of the questions that Alberto got correct on his geography test.

Given that, Alberto got thirty-five out of forty questions correct on his geography test.

We need to determine the

percentage of the questions he got correct, and multiply the quotient of thirty-five and forty by one hundred.

The following formula is a common strategy to calculate a percentage:

Now, 35/40 ×100=87.5%

Therefore, 35/40 ×100 is a numerical expression to describe the percentage of the questions that Alberto got correct on his geography test.

Can you rephrase the question.

Answer:

They will break even... but im not 100% sure im correct

Step-by-step explanation:

Im not 100% sure but here is what i have...

based on the given inequality the new one would be 15n>105+4.50n,

First subtract the 4.50n from the right side of the inequlaity sign.

Now you should have 10.5n>105

second, plug in a random number to see if she will make money or not..

I used 10, so plug 10 in for "N".

it will look like this, 10.5(10)>105

now do the math and get, 105>105,

which brings me to the cunclution she breaks even..

Step-by-step explanation:

- u - v

= - < - 8, 4 > - < 2, 7 >  ← multiply each component of u by - 1

= < 8, - 4 > - < 2, 7 > ← subtract corresponding elements

= < 8 - 2, - 4 - 7 >

= < 6, - 11 >

----------------------------------------------------------

u - v

= < - 8, 4 > - < 2, 7 > ← subtract corresponding elements

= < - 8 - 2, 4 - 7 >

= < 6, - 3 >

-----------------------------------------------------------

v- u

= < 2, 7 > - < - 8, 4 > ← subtract corresponding elements

= < 2 - (- 8), 7 - 4 >

= < 2 + 8, 7 - 4 >
