Answer:

[tex]\boxed{\bold{\huge{\boxed{497}}}}[/tex]

Step-by-step explanation:

=> [tex]\sf 249^2 - 248^2[/tex]

Using Formula [tex]\sf a^2 - b^2 = (a+b)(a-b)[/tex]

Where

a = 249

b = 248

=> [tex]\sf (249+248)(249-248)[/tex]

=> [tex]\sf (497)(1)[/tex]

=> 497

Answer:

The pitcher plant's approximate volume is 24.492 [tex]\text{cm}^{3}[/tex].

Step-by-step explanation:

We are given that a  pitcher is shaped like a cylinder with a radius of 1 centimeter and a height of 7.8 cm.

Let the radius of a cylinder = r = 1 cm

and the height of a cylinder = h = 7.8 cm

As we know that the volume of a cylinder is given by;

The volume of a cylinder = [tex]\pi r^{2}h[/tex]

                           = [tex]3.14 \times 1^{2} \times 7.8[/tex]  {taking approximate value of [tex]\pi[/tex] to be 3.14}

                           = [tex]3.14 \times 7.8[/tex]

                           = 24.492 [tex]\text{cm}^{3}[/tex]

Hence, this pitcher plant's approximate volume is 24.492 [tex]\text{cm}^{3}[/tex].

Answer:

30km/h.

Step-by-step explanation:

100m/12s = 0.1km/12s

There are 3600 seconds in an hour.

0.1km/12s = 30km/h.

Answer:I think it y=73

Step-by-step explanation:

Answer: It is a polynomial, and the degree is 5.

I could be wrong on this but, i'm trying

Step-by-step explanation:

Polynomials in one variable are algebraic expressions that consist of terms in the form axn a x n where n is a non-negative (i.e. positive or zero) integer and a is a real number and is called the coefficient of the term. The degree of a polynomial in one variable is the largest exponent in the polynomial. Also, all exponents have to be positive in a polynomial. Another rule of thumb is if there are any variables in the denominator of a fraction then the algebraic expression isn’t a polynomial.Note that this doesn’t mean that radicals and fractions aren’t allowed in polynomials. They just can’t involve the variables.

The degree is 5 (since the largest exponent is 5)

Examples of Non- Polynomials

Example Polynomial Explanation

5x^-2 +1 Not a polynomial because a term has a negative exponent

3x^½ +2 Not a polynomial because a term has a fraction exponent

(5x +1) ÷ (3x) Not a polynomial because of the division

Answer:

($) 60 is the profit per item when the selling price is reduced by 20%

Step-by-step explanation: 20% of 700 is 140.

The original profit is 700 - 500 = 200. The selling price is 140 less, Subtract 140 from 200. That leaves a profit of 60. (Not necessarily dollars, as the currency was not given in the question.)

Answer:

a) (x, y) = (1, 7)

Step-by-step explanation:

Let be the following system of inequalties:

[tex]y > x^{2}-4\cdot x -5[/tex]

[tex]y < -x^{2}-5\cdot x +6[/tex]

We can find the right option by evaluating each option in the system of inequalities:

a) (x, y) = (1, 7)

[tex]7 > 1^{2}-4\cdot (1) -5[/tex]

[tex]7 < -1^{2}-5\cdot (1) +6[/tex]

Then,

[tex]7>-8[/tex] (TRUE)

[tex]7<0[/tex] (FALSE)

(1, 7) is not a solution of the system of inequalities.

b) (x, y) = (1, -7)

[tex]-7 > 1^{2}-4\cdot (1) -5[/tex]

[tex]-7 < -1^{2}-5\cdot (1) +6[/tex]

Then,

[tex]-7 > - 8[/tex] (TRUE)

[tex]-7< 0[/tex] (TRUE)

(1, -7) is a solution of the system of inequalities.

c) (x, y) = (1, -5)

[tex]-5 > 1^{2}-4\cdot (1) -5[/tex]

[tex]-5 < -1^{2}-5\cdot (1) +6[/tex]

Then,

[tex]-5 > - 8[/tex] (TRUE)

[tex]-5< 0[/tex] (TRUE)

(1, -5) is a solution of the system of inequalities.

d) (x, y) = (-1, 6)

[tex]6 > (-1)^{2}-4\cdot (-1) -5[/tex]

[tex]6 <(-1)^{2}-5\cdot (-1)+6[/tex]

Then,

[tex]6>0[/tex] (TRUE)

[tex]6 < 12[/tex] (TRUE)

(-1, 6) is a solution of the system of inequalties.

Therefore, we conclude that correct answer is A.

Answer:

No, 4 to 7 is not the same as 7 to 4.

Order is important when writing a ratio.

The ratio compares the first quantity to the second.

The ratio 4 to 7 means there are more of the second quantity, but 7 to 4 means there are more of the first.

Answer:1.5783 Miles

1.5783 Miles

Step-by-step explanation:

Multiply the value in Inch (in) by 0.0000157828 (the conversion factor). So,

100000 Inch (in) × 0.0000157828 = 1.57828 Mile.

Answer:

[tex]x=15/2=7.5[/tex]

Step-by-step explanation:

So we have the equation:

[tex]6x-4y=29[/tex]

And we want to find x when y is 4.

So, substitute y for 4:

[tex]6x-4(4)=29[/tex]

Multiply:

[tex]6x-16=29[/tex]

Add 16 to both sides:

[tex]6x=45[/tex]

Divide both sides by 6:

[tex]x=45/6[/tex]

Reduce by dividing both layers by 3:

[tex]x=15/2=7.5[/tex]

And this is our answer :)

Answer:

[tex]7.5 \: or \:7\frac{1}{2}[/tex]

Step-by-step explanation:

[tex]6x- 4 y = 29\\x =?\\y =4[/tex]

Substitute 4 for y in the given equation ;

[tex]6x-4(4)=29\\6x -16=29[/tex]

Collect like terms

[tex]6x = 29+16[/tex]

Simplify

[tex]6x = 45[/tex]

Divide both sides of the equation by 6

[tex]\frac{6x}{6} = \frac{45}{6} \\\\x =\frac{15}{2} \:or \: 7.5 \: or \:7\frac{1}{2}[/tex]

It not a continues number like 1.33333... therefore it is rational. If it went on forever it would be concidered irrational.

Answer:

Yes. 5.67 is a rational no.

Step-by-step explanation:

5.67 is a terminating & non-repeating decimal . And we know that a terminating non-repeating (or repeating  i.e. the decimal would have a bar) decimal no. is a rational number.

5.67 can also be written as  [tex]\frac{567}{100}[/tex]   . A rational is always in the form of   [tex]\frac{p}{q}[/tex]  form where p & q are integers. Hence 5.67 is a rational number.

Answer:

16

Step-by-step explanation:

7x+14=6x+30

Move x into one side and whole numbers to the other.

Solve like linear equation.

7x+14=6x+30

7x-6x=30-14

x=16

Answer:

x = 16

Step-by-step explanation:

7(x+2)=6(x+5) multiply

7x + 14 = 6x + 30 add like terms

7x - 6x = 30 - 14

x = 16

Answer:

b= -2

Step-by-step explanation:

Answer:

b = -2

Step-by-step explanation:

The first thing we need to do to solve this equation is expand the brackets. To so this we need to multiply the outside term with each of the terms inside the bracket (distributive law).

This gives us:

3xb + 3x3 -4x-2 -4xb = 19

Which multiplies out to:

3b + 9 + 8 -4b = 19

Combine like terms:

-b +17 = 19

From here we move the 17 to the other side by subtracting 17 from both sides

-b +17 -17 = 19 - 17

-b = 2

Divide both sides by -1:

-b/-1 = 2/-1

Which gives us:

b = -2

Hope this helped!

Answer:

[tex] \huge \orange { \boxed{x = \frac{c - k}{12} }}[/tex]

Step-by-step explanation:

12x + k = c

Step 1: transfer k on right side

12x = c - k

Step 2: Divide both side by 12

[tex] \frac{12x}{12} = \frac{c - k}{12} \\ \huge \red{ \boxed{x = \frac{c - k}{12} }}[/tex]

Answer:

Step-by-step explanation:

relation is a function if we have y for every x from domain and for one x we have one and only one y

x = 1  --> y = 2

x = 2 --> y = 2

x = -2 --> y = 2

no x-es without y-es

and no two the same x-es with one y

so this relation is a function

Answer:

B. 57.8

Step-by-step explanation:
