3x - y = -6 is answerrrrrrrrrr

Answer:

W = 1.06 MJ

Step-by-step explanation:

- We will use differential calculus to solve this problem.

- Make a differential volume of water in the tank with thickness dx. We see as we traverse up or down the differential volume of water the side length is always constant, hence, its always 8.

- As for the width of the part w we see that it varies as we move up and down the differential element. We will draw a rectangle whose base axis is x and vertical axis is y. we will find the equation of the slant line that comes out to be y = 0.5*x. And the width spans towards both of the sides its going to be 2*y = x.

Answer:

  a) n(A∪B) = 20

  b) n(A) = 31

Step-by-step explanation:

The relevant formula is ...

  n(A∪B) = n(A) +n(B) -n(A∩B)

__

a) n(A∪B) = 5 +18 -3 = 20

b) 32 = n(A) +14 -13   ⇒   n(A) = 31

Answer:

71. 19  72. 100  73. 9  74.1  75. 90  76. 4

Step-by-step explanation:

#71.

Start with 2b-a

Plug in the given numbers where the variables are.

Now the equation is 2(12) - 5

Solve 2(12) - 5

2(12) = 24      24 - 5 = 19

#72.

Start with d(ab-c)

Plug in the given numbers where the variables are.

Now the equation is 2((5×12) - 10)

Solve in the parenthesis first.

5×12= 60    60-10=50    2(50)= 100

#73.

Start with 3+ [tex]\frac{b}{d}[/tex]

Plug in the given numbers where the variables are.

Now the equation is 3+ [tex]\frac{12}{2}[/tex]

Solve.

[tex]\frac{12}{2}[/tex] = 6    3+6 = 9

#74.

Start with [tex]\frac{4a}{b+4d}[/tex]

Plug in the given numbers where the variables are.

Now the equation is [tex]\frac{4(5)}{12+(4x2)}[/tex]

Solve.

4(5)= 20    

(4×2)= 8    12+8= 20

Now the fraction is  [tex]\frac{20}{20}[/tex] = 1

#75.

Start with 2a² - c

Plug in the given numbers where the variables are.

Now the equation is 2(5)² - 10

Solve 2(5) = 10      10² = 100  100-10= 90

#76.

Start with b - c + d

Plug in the given numbers where the variables are.

Now the equation is 12 - 10 + 2

Solve.

12 - 10 = 2     2 + 2 = 4

Answer:

B. 27+3√5/76

Step-by-step explanation:

3/9-√5

~Multiply the conjugate to everything (9 + √5)

3(9+√5)/(9-√5)(9+√5)

~Simplify

27+3√5/76

Best of Luck!

Answer:

equation is y= 50 + 3f

57F

15 Minutes

Step-by-step explanation:

a) the equation above because 50 is the starting temp and every 3 minutes is another degree F

b) if the temp rises 1 degree every 3 minutes, then 21/3 is 7 degrees hotter plus 50, which is 57 F.

c) if 50 plus 3f is the equation, then 3 times 5 will make 55 degrees. After 15 minutes, the temp will be 55 F.

Step-by-step explanation:

1.Add 3 t0 both sides of the equation.

● 8n-3= -5

● 8n-3+3= -5+3

2.Simplify.

● 8n= -5+34

● 8n= -2

3.divide both sides of the equation by same terms.

● 8n = -2

Answer:

20,600,000,000

Step-by-step explanation:

When writing a number in standard notation from scientific notation, counting decimal places is important. In this case, the exponent of 10 is 10. That means the decimal place must be moved 10 places; since it is positive the decimal place should be moved to the right. Finally, fill any empty spaces when moving the decimal point with zeros.

If the vectors [tex]\{\mathbf v_1,\mathbf v_2,\ldots,\mathbf v_p\}[/tex] span [tex]\mathbb R^n[/tex], then any vector [tex]\mathbf x\in\mathbb R^n[/tex] can be expressed as a linear combination of these vectors. This means there exist scalars [tex]\{c_1,c_2,\ldots,c_p\}[/tex] such that

[tex]\mathbf x = c_1\mathbf v_1 + c_2\mathbf v_2 + \cdots + c_p\mathbf v_p[/tex]

Since T is a linear transformation, we have for all x,

[tex]T(\mathbf x) = T(c_1\mathbf v_1 + c_2\mathbf v_2 + \cdots + c_p\mathbf v_p) \\\\ T(\mathbf x) = c_1T(\mathbf v_1) + c_2T(\mathbf v_2) + \cdots + c_pT(\mathbf v_p) \\\\ T(\mathbf x) = \mathbf 0 + \mathbf 0 + \cdots + \mathbf 0 = \mathbf 0[/tex]

Answer:

so the second one

4 * (-9) * (-3) * (-1)

Step-by-step explanation:

-2 * (-7) * 12 * 4 = positive

4 * (-9) * (-3) * (-1) = negative

-6 * (-7) * (-8) * 0 = positive

-3 * (-2) * (-4) * (-7) = positive

negative times negative = positive

Answer:

The better one is $6 for 24 oz bottle

Step-by-step explanation:

If it cost 4 dollars for a 12 oz bottle and that would cost 1 dollar per 3 oz but for the 6 dollar for a 24 oz bottle it would be 1 dollar per 4 oz so 6 dollars for a 24 oz bottle is better!

The cost of Ferry ticket is $9.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, the train ticket costs $45.

Let the cost of Ferry ticket be x.

The train ticket costs 5 times as much as the Ferry ticket.

Now, the cost of train ticket =5x

45=5x

x=$9

Therefore, the cost of Ferry ticket is $9.
