When I subtract 14 from it,
the result is 13 more than 20.
what is the number? ​

The solution of the inequality are n  ≤ -7 and n ≥ -12.

A compound inequality is an inequality that combines two simple inequalities.

Therefore, let's solve the compound inequality individually.

n + 2 ≤ −5 and  n + 6 ≥ −6

Hence,

n + 2 ≤ − 5

subtract 2 from both sides of the inequality

n + 2 - 2 ≤ − 5 - 2

n  ≤ -7

n + 6 ≥ −6

subtract 6 from both sides of the inequality

n + 6 ≥ −6

n + 6 - 6 ≥ −6 - 6

n ≥ -12

Therefore, n  ≤ -7 and n ≥ -12

The number of images formed by two mirrors kept at an angle of 72° are;

5 images, If the object is positioned symmetrically between the mirrors

4 images if the object is placed asymmetrically between the mirrors

The formula that can be used to find the number of images formed, n, when two mirrors are placed at a specified angle, θ, to each other is presented as follows;

If [tex]\dfrac{360^{\circ}}{\theta}[/tex] is an even number, the number of images formed is obtained using the formula;

If [tex]\dfrac{360^{\circ}}{\theta}[/tex] is an odd number, the number of images formed is obtained using the formula;

If [tex]\dfrac{360^{\circ}}{\theta}[/tex] is an odd number, and the position of the object is asymmetric, the number of images formed is obtained using the formula;

When θ = 72°, we get;

[tex]n = \dfrac{360^{\circ}}{72^{\circ}} = 5[/tex], which is an odd number, therefore;

If the object is placed symmetrically between the two mirrors, the number of images formed is therefore;

[tex]n = \dfrac{360^{\circ}}{72^{\circ}}-1 = 4[/tex]

No, it depends upon the size of the bottle but it's not enough for a normal bottle to make 6 frozen juice bars.

No, 2 cups of orange juice is not enough to make 6 frozen juice bars. Each frozen juice bar typically requires a certain amount of juice, and it is likely that 6 bars would require more than 2 cups of juice. To be sure, you would need to check the recipe or packaging for the frozen juice bars to determine the exact amount of juice required per bar.

It is also important to note that even if the juice is enough to make 6 bars, it might not yield the same taste as desired because of the lack of enough juice, also the freezing process might not work as well as it should because of the small quantity of juice.

Therefore, It is not enough as it depends upon the size of the bottle but it's not enough for a normal bottle to make 6 frozen juice bars.

The possible measures of the other two angles would be -

56° and 68° respectively.

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane

Given is that one angle of an isosceles triangle measures 56°.

Angles opposite to equal sides are equal. In a isosceles triangle, two sides are equal. So, we can write -

∠1 = ∠2 = 56°    {Angles opposite to equal sides are equal}

∠3 + ∠1 + ∠2 = 180

∠3 = 180 - 2 x 56

∠3 = 180 - 112

∠3 = 68°

The cost of a family pack of 45 chicken nuggets = 6.75 dollars

Given that Burger Mania sells 10 chicken nuggets for $1. 50

First we find the cost of one chicken nugget.

10 chicken nuggets = 1. 50 dollars

So, 1 chicken nugget = (1.50) / 10 dollars

                                  = 0.15 dollars

                                  = 15 cents

We need to find the cost of 45 chicken nuggets.

Using Unitary method the cost of 45 chicken nuggets would be,

45 × 0.15 = 6.75 dollars

A movie is not a real image, it is a series of still images or frames that are played back in rapid succession to create the illusion of motion.

Real images are those that are formed by light that has been refracted or reflected by an object or lens. These images are located on the same side of the lens as the object and can be projected onto a screen or viewed directly.

In movie, the images are typically captured on film or digitally and then played back on a screen at a high frame rate (usually 24 or 30 frames per second) to create the illusion of motion.

This is known as the persistence of vision effect. The images are not actually moving, but the human eye and brain perceive them as moving because of the rapid succession of still images.

In conclusion, a movie is not a real image, it is a series of still images played back in rapid succession to create the illusion of motion.

The depth of water in the tank is increasing at the rate of approximately 0.0135 meters per minute when the depth is 8 meters.

A cone is a three-dimensional geometric structure with a smooth transition from a flat base—often but not always circular—to the point at the top, also known as the apex or vertex.

To find the rate at which the depth of water in the tank is increasing, we can use the formula for the volume of a cone:

V = (1/3) * π * r^2 * h

Where V is the volume, π is pi, r is the radius, and h is the height (depth) of the cone.

We know that the radius at the top of the tank is 15 meters, the depth of the tank is 8 meters, and the rate of water flow is 2 cubic meters per minute.

So we can use the above formula to find the rate at which the depth is increasing.

Let's call the rate at which the depth is increasing "dh/dt"

V = (1/3) * π * 15^2 * 8

dV/dt = (1/3) * π * 15^2 * dh/dt

Now we know that the rate at which the water is flowing is 2 cubic meters per minute, so we can substitute it for dV/dt

2 = (1/3) * π * 15^2 * dh/dt

Solving for dh/dt

dh/dt = 2/( (1/3) * π * 15^2 )

Therefore, the depth of water in the tank is increasing at the rate of approximately 0.0135 meters per minute when the depth is 8 meters.

Answer:

Step-by-step explanation:

7 + 12x - 3x² ( rearrange terms in x )

7 - 3x² + 12x ( factor out - 3 from each of the x- terms )

= 7 - 3(x² - 4x)

using the method of completing the square on x² - 4x

add/subtract ( half the coefficient of the x- term )² to x² - 4x

= 7 - 3(x² + 2(- 2)x + 4 - 4)

= 7 - 3(x - 2)² - 3(- 4)

Finding a number's square root is the equivalent as squaring it, or the opposite process. When you multiply the square root of a given integer by itself, you get the original number. Since 8 x 8 equals 64, as fact, 8 is the square root of 64.

It is possible to multiply an integer by its square root in order to obtain the original value. Square root of, end square root is the symbol for this mathematical concept. Contrary to squaring, finding a number's square root is the reverse. For instance, 3 is squared at 9, 32, and its square root at 9, which is 9, is equal to 3. It is simple to multiply by 9 since it is a perfect square.

An interior angle of a regular decagon is given by the formula (n-2) * 180 / n, where n is the number of sides. Since a decagon has 10 sides, the measure of each interior angle is (10-2) * 180 / 10 = 160 degrees.

The measure of each exterior angle of a regular polygon is given by the formula 360 / n, where n is the number of sides. So in the case of a decagon, each exterior angle measures 360 / 10 = 36 degrees.
