evaluate the expression 7^2/ x^2 - 2 for x = 3

Answer:

Remaining amount is 6.25 gram

Step-by-step explanation:

After one year what you would be left with is 50/2 which is 25 gram

After the second year, you would be left with 50/4 which is 12.5

After the third year what's left is 50/8 i.e 6.25

Answer:

6x-8=5x+14

x=22

this is the solution

(6x-8)°=(5x+14)°

_ _ _ _ _ +14= _ _ _ _ _ _-8= x=14+8=22°

(6×22-8)°=124°

(5×22+14)=124°

Answer:

Base, b = 4.5 yards

Step-by-step explanation:

Given the following data;

Area of triangle = 45 square yards

Height = 20 yards

To find the base of the triangle;

Mathematically, the area of a triangle is given by the formula;

Area of triangle = ½ * b * h

Where;

b is the base of the triangle.

h is the height of the triangle.

45 = ½ * b * 20

90 = 20b

Base, b = 90/20

Base, b = 4.5 yards

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

Since the scale is in equilibrium, both sides must be equal. Therefore, we have the following equation:

[tex][\text{Left Side} ]3x+3=[\text{Right Side}]9[/tex]

Solving for [tex]x[/tex]:

[tex]3x+3=9,\\3x=6,\\x=\boxed{2}[/tex]

Answer:x=2

Step-by-step explanation: try to first set up an equation. First we can see the scale is balanced so we know each side is equal to each other. You have 3 x boxes and 3 circles so our first side will be 3x+3. Now let’s move onto the second side. It has 9 circles so 3x+3=9. Now let’s solve!

Subtract 3

3x=6

Now divide by 3

X=2

Answer:

72 in²

Step-by-step explanation:

lateral area: the surface area of a 3D figure, but excluding the area of any bases

the lateral area of this prism is the sum of the three rectangular sides.

calculate the third side of the triangle first because it's also the side of one of the rectangle:

√(5² - 4²) = 3

4 × 6 + 5 × 6 + 3 × 6 = 72

Answer:

-6x² - 11x - 3

Step-by-step explanation:

This represents the product of the two functions.

(-2x-3)(3x+1) = -(2x+3)(3x+1) = -(6x² + 11x + 3) = -6x² - 11x - 3

Answer:

2. 9x - 4= 12x - 55

9x - 12x = -55+4

-3x = -51

x = 17

3. 7x +29 = 11x - 31

7x - 11x = -31-29

-4x = -60

x =15

Answer:

first spot 10, second 16, third 18, fourth 22

Answer:

The expression that represents the table is

y=4+2x

when x=3

y=4+2(3) = 10

When x=6

y=4+2(6)= 16.

Do this for all the values of x and you'll get the corresponding value for y

Answer:

The product of sin 30° and sin 60° is the same as the the product of cos 30° and cos 60°.

The product of sin 30° and sin 60° is same as the product of cos 30° and cos60°.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We know that the sine function is a ratio of opposite side and hypotenuse.

The cosine function is a ratio of Adjacent side and hypotenuse.

Let us find the product of sin 30° and sin 60°

=sin 30°.sin 60°

=1/2.√3/2

=√3/4

Now we know that  cos 60° is 1/2 and  cos 30° is √3/2

Product cos 60° and cos 30°

cos 30°.cos 60°=1/2.√3/2

=√3/4

Hence, the product of sin 30° and sin 60° is same as the product of cos 30° and cos60°.

MARK ME BRAINLIST

Answer:

It will cost the company $179,604.

Step-by-step explanation:

Multiply the cost of 1 car by the number of cars needed:

19,956 × 9

179,604

9514 1404 393

Answer:

  {587, 1}

Step-by-step explanation:

The sum will be minimized when the second number is as close to zero as is allowed. If the numbers must be positive integers, the sum is minimized when the numbers are {587, 1}.

If the numbers may be real numbers, then the values that minimize the sum are {588-, 0+}

_____

The "cost" of taking a unit from the sum 588 and assigning it to the second number is that the sum of first and 3 times the second goes up by 3. In order to minimize that sum, the second number must be minimized.

[tex]\frac{1}{14}[/tex] is half of [tex]\frac{1}{7}[/tex]

This would be true because half of a number can be found by multiplying by [tex]\frac{1}{2}[/tex]

If you multiplied [tex]\frac{1}{7} * \frac{1}{2}[/tex]

The numerator is 1 * 1 which is 1

And then the denominator is 7 * 2 which is 14

That would give you [tex]\frac{1}{14}[/tex]

The products of two reciprocals is 0

This is not true

Reason being, reciprocals are just the number flipped. If you times the number by itself, you don't get 0, you get 1.

Ex: [tex]\frac{2}{8}[/tex]

Its reciprocal is [tex]\frac{8}{2}[/tex]

So multiply them together

[tex]\frac{2}{8}* \frac{8}{2}[/tex]

2 * 8 = 16

8 * 2 = 16

[tex]\frac{16}{16} = 1[/tex]

i.

A whole number does not have a reciprocal

This is incorrect. If you think about it, a whole number is just the number, over 1

Ex: [tex]\frac{6}{1}[/tex]

This is still a whole number even though its written in fraction form because if you divide 6 by 1, your still going to get 6.

If you an write it as a fraction, it has a reciprocal.

The reciprocal in this case would be [tex]\frac{1}{6}[/tex]
