Answer:

25 or 26 depending if your rounding if you're not rounding it's 25.7495

Given:

The equation is:

[tex]8x^3=(-2x)A[/tex]

To find:

The missing factor AAA that makes the equality true.

Solution:

We have,

[tex]8x^3=(-2x)A[/tex]

Divide both sides by -2x to isolate A.

[tex]\dfrac{8x^3}{-2x}=A[/tex]

[tex]-4x^2=A[/tex]

Therefore, the value of A is [tex]-4x^2[/tex].

Answer:

10 weeks, Substituion Equation.

Step-by-step explanation:

(Assume that x= 'per week').

We can write this as 50 + 25x=y for Heather's savings, &

                               200 + 10x=y for Alssa's savings.

We can combine these equations to make 200 +10x= 50+25x, because we know 50+25x=y, like we found out in the first equation. We can now subtract 25x from each side, and subtarct 200 from each side, to get

10x - 25x = 50 - 200, which can be simplified to -15x=-150. If we divided each side by -15, we get 10. Therefore, it will take 10 weeks for them to have the same amount of money. I think this is the Substituaion Equation

Answer: Im not giving answer to that but i will do this one

A water tank holds 256 gallons but is leaking at the rate of 3 gallons per week. A second water tank holds 384 gallons and is leaking at a rate of 5 gallons per week.After how many weeks will the amount of water in the two tanks be the same.

Step-by-step explanation:

you have: one is leaking 3 gallons per week and holds 256 gallons; whereas, the other one is leaking 5 gallons per week and holds 384 gallons.

Set up both the equations....

In y=mx+b form--->>>

y=-3x+256

y=-5x+384

To figure out when they will be equal..set the equations equal to each other....(remember to isolate the variable)

-3x+256=-5x+384

-3x+256=-5x+384

     -256        -256

-3x=-5x+128

-3x=-5x+128

+5x+5x

2x=128

x=64

After 64 weeks the amount of water in both tanks will be the same.

Thus, your answer.

Answer:

36

Step-by-step explanation:

Hey There!

So if you didn't know all of the angles in a triangle add up to equal 180

so to find the missing angle we subtract the given angles from 180

180-90-54=36

therefore the missing angles is 36

Answer:

36

Step-by-step explanation:

180 degrees in a triangle

that little square means its a right angle therefore it is 90 degrees

90+54=144

180-144=36

Answer:

-2/3

Step-by-step explanation:

h(x)=2x-6/4x^2+8

You know that h is equal to -1 so you have to plug that into x.

2(-1)-6/4(-1)^2+8. Simplify this to get -2-6/4+8 which is equal to -8/12. The GCM of 8 and 12 is 4 so you have to divide both sides by 4. This will make the fraction -2/3.

If this has helped you, please mark the answer as brainliest

Answer: [tex]h(-1) = \frac{-2}{3}[/tex]

Step-by-step explanation:

You simply substitute -1 for x

h (-1) = 2 (-1) - 6 ÷ (4 × -1² + 8)

h (-1) = (-2 - 6) ÷ (4 × 1 + 8)

h (-1) = (-2 -6) ÷ (4 + 8)

h (-1) = -8 ÷ 12 = -2 ÷ 3

h (-1) = ⁻²/₃

Mean = 28.3 , Median = 28.5, Mode = 35, Standard deviation = 5.2

(All of the above are rounded off to one decimal place)

The given data are : 20, 22, 26, 27, 30, 31, 35, 35

We know that, mean = (sum of samples)/(no. of samples)

                                   = (20+22+26+27+30+31+35+35)/8

                                   = 226/8 = 28.25 = 28.3 (approx)

Here, median = (sum of 4th & 5th sample)/2

                       = (27+30)/2 = 57/2 = 28.5

Since 35 appears highest number of times, i.e. 2 times, then we can say that mode is equals to 35

Standard deviation = √{(20-28.3)²+(22-28.3)²+(26-28.3)²+(27-28.3)²+(30-28.3)²+(31-28.3)²+(35-28.3)²+(35-28.3)²}/8

= √{68.89+39.69+5.29+1.69+2.89+7.29+44.89+44.89}/8

= √(215.52/8) = √(26.94) = 5.190 = 5.2 (approx)

Answer:

sorry just need points

Step-by-step explanation:

Just need points g

Answer:

Yes

Step-by-step explanation:

This is because the first point in the parenthesis is x and the second is y. If we know this, we can substitute -5 in for x and -6 in for y to get that -15 - (-12) > -4. When you subtract by a negative number, it is the same as adding by that number, so -15 - (-12) = -15 + 12, so we get that -3 > -4. This is true because when you have negative numbers, the lesser negative number is the greater one (Ex. -5 > -6).

Answer:

34.5

Approximately= 35

Step-by-step explanation:

The ratio of the number of boys= 8

Ratio of number of girls= 5

Total ratio= 8+5=13

number of boys in that class =52

Let total number of students= X

Ratio of number of boys= 8/13 × X=52

= 8X/13 = 52

8X=13 × 52

8X= 676

X= 84.5

Then, the number of girls= (84.5-50)

34.5

Answer:

the answer is 84.5-50 is the answer

Answer:

(-1,1),(-3,-19)

Step-by-step explanation:

y=−3x²−2x+2     (1)

10x−y=−11

y=10x+11    (2)

−3x²−2x+2 = 10x+11

3x² + 12x + 9 = 0

x²  + 4x + 3 = 0

(x + 1)(x+3) = 0

x= -1 or x = -3

y = 1 or y = -19

The solutions of the equations y = −3x² − 2x + 2 and 10x − y = −11 will be (-1, 1) and (-3, -19).

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equations are given below.

y = −3x² − 2x + 2         ...1

10x − y = −11                ...2

From equations 1 and 2, then we have

10x + 11 = −3x² − 2x + 2

3x² + 12x + 9 = 0

x² + 4x + 3 = 0

x² + 3x + x + 3 = 0

x(x + 3) + 1(x + 3) = 0

(x + 3)(x + 1) = 0

x = -1, -3

The value of y at x = - 1 is given as,

y = 10(-1)  + 11

y = 1

The value of y at x = -3 is given as,

y = 10(-3)  + 11

y = - 19

The solutions of the equations y = −3x² − 2x + 2 and 10x − y = −11 will be (-1, 1) and (-3, -19).

Step-by-step explanation:

5x(2+6x-5y)+2y(2+3y-4x)

10x+(30x^2)-25xy + 4y+(6y^2)-8yx

For the first, simply plug in the value of x given (x = 2) into the equation: [tex]\left\frac{3}{4}x^2 + 5\right.|_{x=2} = \frac{3}{4}\left ( 2^2 \right )+5 = 8.[/tex]

So, 8 would be your answer.

For the second, the sum of x and 2 would be expressed as x + 2. Twice this sum would be written as 2(x+2). Finally, 8 less than twice that sum would be written as 2(x+2) - 8, which would be your expression.

For the last question, the coefficient refers to the number directly in front of the variable, x. So you need only to check what the x would simplify to in each equation and look for the expression where x has no coefficient (i.e., its coefficient is 1). For Hunter, the coefficient would be 15 (5 × 3x = 15x); for Michael, the coefficient would be 11 (6x + 5x = 11x); for Nate, the coefficient would be 1 (x = 1x); and for Spencer, the coefficient would be 2 (2x = 2x). Thus, Nate's expression has a coefficient of 1 when simplified.

Answer:

Step-by-step explanation:

We shall use the pythogorean theorem. So, the hypotenuse is 37 and 15 is a^2.

So, we will have:

[tex]15^2+x^2=37^2[/tex]

Then, we will have:

[tex]225+x^2=1369[/tex]

Then, we will subtract 225 from both sides:

[tex]x^2=1144[/tex]

We will then have:

[tex]\sqrt{4\cdot286} = \sqrt{2^2\cdot286} \text{the 2 gets canceled out and we will get}\\2\sqrt{286}[/tex] which is in simplest form.
