In a kitchen there are three containers that can hold different quantities of water, as shown in the figure below:

Three containers of the same shape but different sizes are shown, starting with the shortest and ending with the longest. The following quantities are written below the containers. x minus 10 liters below the first, x minus 5 liters below the second, and x liters below the third.

How many liters of water can the three containers hold in all?

x − 15
3x − 15
x3 + 50
3x3 − 15

I'll split this figure up in three sections, 65*60, 70*190, and 95*140.

95*140=13300

70*190=13400

65*60= 3900

Add the three areas of the three figures I have split the original figure into and you get 30600 ft²

Answer:

Equation:

HCL + HCL = HCL

0.30x + 0.45(50-x) = 0.35*50

Multiply thru by 100 to get:

30x + 45*50 - 45x = 35*50

-15x = -10*50

x = (2/3)50

x = 33 1/3 liters (amt. of 30% solution needed in the mixture)

50-x = 16 2/3 liters (amt. of 45% solution needed in the mixture)

=============

Step-by-step explanation:

Answer:

about 36 and 24 liters  

Step-by-step explanation:

    a+b = 60     1

let A multiplied by  10 percent and B multiplied by 35 percent then

  10 a + 35 b = 1500 ( 60 * 25 ) 2

add no. 1 to 2 and multiply no.1  by -10

-10 a+ -10 b = -600

10 a+ 35 b = 1500  adding

then     25 b = 900 then         b = 36 liter

then     a = 24 liter

Answer:

[tex]\$16.64[/tex]

Step-by-step explanation:

we know that

The exponential function while the player is still active is equal to

[tex]y=3(1.07)^{x}[/tex]

where

y ----> is the value of the baseball card

x ----> the time in years

Find the value of y for x=7 years (7 years still active)

[tex]y=3(1.07)^{7}=\$4.82[/tex]

After 20 years

x=20-7=13 years (13 years retired player)

The initial value is [tex]\$4.82[/tex]

The new equation is equal to

[tex]y=\$4.82(1.1)^{x}[/tex]

substitute

x=13 years

[tex]y=\$4.82(1.1)^{13}=\$16.64[/tex]

Answer:

lower your mortgage interest rate

Step-by-step explanation:

The higher your credit score, the __lower your mortgage interest rate__.

Because the higher your credit score, the less risk you represent for a lender, so it will most likely grant you a lowest rate for your mortgage/loan.

The "lower your savings interest rate " is not the answer because savings interest rates are not related to the credit score...

"higher your car loan rate " and "higher risk you are to a creditor " are consequences of a low credit score.

Answer:

(3ab^3+2c^6)(9a^2b^6-6ab^3c^6+4c^12)

Step-by-step explanation:

Given:

Polynomial 27a^3 b^9+8c^18

Factoring the given polynomial

27a^3b^9 can be written as

=3^3.a^3.b^3^3

=(3ab^3)^3

Also 8c^18 can be written as

=2^3.c^6^3

=(2c^6)^3

Hence Polynomial 27a^3 b^9+8c^18 can be written as

=(3ab^3)^3+(2c^6)^3

Applying sum of cubes formula i.e. a^3 + b^3=(a+b)(a^2 – ab + b^2)

=(3ab^3+2c^6)(9a^2b^6-6ab^3c^6+4c^12) !

I think it would be x = 3 and y = 2 based on another question I read like this.

it's D because when you distribute the -x the 5x multiplies to -5x^2 then -4 multiplies to 4x since the negatives cancel out.

Answer:

85 kilometers is equal to 85 000 meters

Step-by-step explanation:

1 kilometer is equivalent to 1000 meters. Then to convert from kilometers to meters use the following conversion factor

[tex]x\ kilometers * \frac{1000\ meter}{1\ kilometers }[/tex]

In this case [tex]x=85[/tex]

Then

[tex]85\ km* \frac{1000\ m}{1\ km} =85,000\ m[/tex]

Finally 85  kilometers = 85,000 meters

Answer:

Step-by-step explanation:

1km - one kilometer

kilo - 1,000 times more

1km = 1,000m

Answer: OPTION B

Step-by-step explanation:

Multiply both denominators to find the Least Common Denominator:

[tex]LCD=(3y-4)(y^2)[/tex]

Now, divide each original denominator by the LCD and multiply the result by each numerator. Then:

[tex]=\frac{(6y^2+2y)(y^2)-(9y-7)(3y-4)}{(3y-4)(y^2)}[/tex]

Applying Distributive property, you get:

[tex]=\frac{6y^4+2y^3-(27y^2-36y-21y+28)}{3y^3-4y^2}\\\\=\frac{6y^4+2y^3-27y^2+36y+21y-28}{3y^3-4y^2}[/tex]

Add the like terms in the numerator:

Answer:

1- none of the choices are correct.

2-none of the answer choices are correct.

Step-by-step explanation:

1- there is no k therefore none are correct because they all offer a solution for k

2- yes the parabola opens upward but none are right in the right mix for the other two. the vertex is at (0,-5) and the axis of symmetry is x = 0 (not only because I calculated it and the graph showed it but because (x,y) And the x spot is a 0)

any time you just see a plain x^2 or really anything like that in the same vanilla sense wether the exponent is changed or there is a coefficient and all it has is a plus or minus whatever it will just be along the y axis where the plus or minus number was. (can't remember any vanilla advice for parabolas sorry)

Answer:

1. a=5,h=0,k=0

2. None of the choices are correct

Step-by-step explanation:

1. The function given is:[tex]f(x)=5x^2[/tex]

We can rewrite this in vertex form as: [tex]f(x)=5(x-0)^2+0[/tex].

Comparing this to [tex]f(x)=a(x-h)^2+k[/tex], we have a=5,h=0 and k=0.

The first choice is correct

2. The function given is: [tex]f(x)=x^2-5[/tex]

This can be rewritten in the vertex form as:

[tex]f(x)=a(x-0)^2-5[/tex]

Comparing this to [tex]f(x)=a(x-h)^2+k[/tex], we have a=1,h=0 and k=-5.

Since 'a' is positive, the parabola opens upwards, and has its vertex at (h,k)=(0,-5), and line of symmetry at x=0.

Based on this, the correct choice is none of the choices are correct

Answer:

incorrect

Answer:

37.5 [tex]units^2[/tex]

Step-by-step explanation:

As the area of each of the side of the cube are the same we can multiply the area of one side by 6.

The area of one side is

[tex]2.5*2.5=6.25\\\\6.25*6=37.5[/tex]

Answer:

37.5

Step-by-step explanation:

Surface area of a rectangular prism (a cube is a rectangular prism) is 2B + Ph

B is area of the base so do width x length. In cube all side lengths are the same, so do 2.5 x 2.5.

B= 6.25

P is perimeter of base so do 2.5 + 2.5 + 2.5 + 2.5 = 10

P=10

h is the height of the prism, but all sides are the same anyway so it's 2.5

h=2.5

2(6.25) + 10(2.5)

12.5 + 25

37.5

The answer is:

x=-8

Because:

If you pick a number(-8) to fill in the equation written below

5x+20+5x=5x-20

After applying the -8 to x you get

-40+20-40=-40-20

When you simply the both sides you get

-60=-60

And that’s right -60 is equal to -60!

Answer:

Third option : x = -8

Step-by-step explanation:

Given

5x+20+5x=5x-20

in order to solve the equation, Subtracting 5x on both sides

5x+20+5x-5x=5x-20-5x

5x+20= -20

20 will be subtracted from both sides

5x+20-20= -20-20

5x= -40

Dividing by 5 on both sides

5x/5=  (-40)/5

x= -8

So, the value of x is -8 ..

Answer:

20

Step-by-step explanation:

Write as an equation (in order to represent the question better):

9x - 4 = 176

Add 4 to both sides (to remove the '-4' on the left-hand side):

9x = 180

Divide both sides by 9 (to find x):

x = 20

For this case we must make a conversion. By definition, we have to:

1 liter equals 1000 milliliters.

So, we make a rule of three:

1L ------------> 1000mL

x ---------------> 1580mL

Where the variable "x" represents the amount of liters equivalent to 1580 milliliters.

[tex]x = \frac {1580 * 1} {1000}\\x = 1.58[/tex]

Thus, 1580 milliliters equals 1.58 liters.

90 - 49.32 = 40.68

Answer:

68% of exam scores lie within one std. dev. of the mean

Step-by-step explanation:

Because the standard deviation is 100, one standard deviation above the mean comes out to 600.  Likewise, one std. dev. below the mean comes out to 400.  By the Empirical Rule, 68% of exam scores lie within one std. dev. of the mean.

Answer:

[tex]P(400<x<600) = 68.3\%[/tex]

Step-by-step explanation:

We know that the average [tex]\mu[/tex] is:

[tex]\mu=500[/tex]

The standard deviation [tex]\sigma[/tex] is:

[tex]\sigma=100[/tex]

The Z-score is:

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

We seek to find

P(400<x<600)

This is:

[tex]P(400<x<600)=P(\frac{400-500}{100}<\frac{x-\mu}{\sigma}<\frac{600-500}{100})\\\\P(400<x<600)=P(-1<Z<1)[/tex]

Looking for the value of z in a normal table we have to:

[tex]P(Z>1) =0.1587\\\\P(Z>-1) = 0.8413[/tex]

So

[tex]P(-1<Z<1)=P(Z>-1) - P(Z>1) =0.8413-0.1587=0.6826\\\\P(400<x<600) = 68.3\%[/tex]

x^2+8x-2=18

x^2+8x-2-18= 18-18

x^2+8x-20= 0

x-2+2= 0+2, x+10-10= 0-10

x=2 , x=-10

Answers are x= 2 -B, x=-10 -A.

Answer:

Option A and B

Step-by-step explanation:

Given : Quadratic equation [tex]x^2+8x-2=18[/tex]

To find : Complete the square to solve the equation below check all that apply ?

Solution :

Re-write, [tex]x^2+8x-2=18[/tex]

[tex]x^2+8x-20=0[/tex]

Applying quadratic formula,

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Here, a=1 , b=8, c=-20

[tex]x=\frac{-8\pm\sqrt{8^2-4(1)(-20)}}{2(1)}[/tex]

[tex]x=\frac{-8\pm\sqrt{64+80}}{2}[/tex]

[tex]x=\frac{-8\pm\sqrt{144}}{2}[/tex]

[tex]x=\frac{-8\pm12}{2}[/tex]

[tex]x=-4\pm6[/tex]

[tex]x=-4+6,-4-6[/tex]

[tex]x=2,-10[/tex]

The solution of the equation is x=2,-10.

Therefore, Option A,B satisfy the equation.

Answer:

Your total investment increase by $105.00 by second year.

Step-by-step explanation:

You bought 200 shares at the price = $15.25 per share

Total cost of 200 shares = 200 × 15.25 = $3050

First year your investment gains profit = 10%

10% of 3050 = [tex]\frac{10}{100}[/tex] × 3050

= 0.10 × 3050 = $305

Total value of 200 shares on first year = 3050 + 305 = $3,355

Then loses $1.00 per share the second year = 200 × 1.00 = $200

on second year the value of 200 shares would be = 3,355 - 200 = $3,155

So profit by second year = 3,155 - 3050 = $105

Your total investment increase by $105.00 by second year.
