You have 36 apples to share with your friends. If each friend gets exactly 2 apples, which equation could you use to solve for the number of friends, n?

Answer:

(10, 4)

Step-by-step explanation:

The horizontal distance from (-4, -2) to the midpoint (3, 1) is 7, and the vertical distance is 3.  To find the other end point of this line segment, add 7 to the x-coordinate of the midpoint:  3+7 = 10, and add 3 to the y-coordinate of the midpoint:  1 + 3 = 4.  The coordinates of the other end of this segment are thus (10, 4) (the fourth possible answer choice).

Answer:

x = 72 degrees

Step-by-step explanation:

If triangle LMN = triangle QPR, that means:

- angle L (x) equals angle Q

- angle M equals angle P

- angle N equals angle R

We know angle Q equals 72 degrees and we know angle Q equals angle L. Since angle L is the "x" we are looking for, we know that x = 72 degrees.

Answer:

$550

Step-by-step explanation:

You need the equation E(s) = 350 + 0.15s, where E(s) represent his total weekly earnings.

If he earned $432.50 this means E(s) = 432.50 and you can write it as:

350 + 0.15s = 432.50 and this is the equation we need to solve

You need to substract 350 on both sides of the equation

350 - 350 +0.15 s = 432.50 - 350

And we get

0.15s = 82.5

Then we divide both sides of the equation by 0.15

0.15s/0.15 = 82.5/0.15

And we get s = 550.

Answer:

z = -0.4.

Step-by-step explanation:

Here's the formula for finding the z-score (a.k.a. standardized normal variable) of one measurement [tex]x[/tex] of a normal random variable [tex]X \sim N(\mu,\; \sigma^{2})[/tex]:

[tex]\displaystyle z = \frac{x-\mu}{\sigma}[/tex],

where

Let the length of a trout in this lake be [tex]X[/tex] inches.

[tex]X \sim N(30, \; 4.5^{2})[/tex].

For this measurement, [tex]x = 28.2[/tex]. Apply the formula to get the z-score:

[tex]\displaystyle z = \frac{x - \mu}{\sigma} = \frac{28.2 - 30}{4.5} = -0.4[/tex].

You add/subtract complex numbers simply by adding/subtracting real parts and imaginary parts.

So, the real part of this sum is the sum of the real parts:

[tex]-3+6=3[/tex]

And the imaginary part of this sum is the sum of the imaginary parts:

[tex]5i+2i=7i[/tex]

So, you have

[tex](-3+5i)+(6+2i) = 3+7i[/tex]

EXPLANATION

The given function is

g(x)=f(x+1)

This means that the base function is:

f(x).

The translation f(x+k) will shift the graph to left by k units while f(x-k) will shift the graph to right by k units

Therefore if g(x)=f(x+1) translates the function f(x) 1 unit left.

Answer: left

Answer:

g(x) translates the function f(x) 1 unit left.

Step-by-step explanation:

Consider the provided function.

g(x)=f(x+1)

Transformation:

Rule 1:  The graph of parent function f(x) move up b unit for f(x)+b.

Rule 2: The graph of parent function f(x) move down b unit for f(x)-b.

Rule 3: The graph of parent function f(x) move left b unit for f(x+b).

Rule 4: The graph of parent function f(x) move right b unit for f(x-b).

From the rule 3  we can say that the graph of parent function move left 1 unit for g(x)=f(x+1)

g(x) translates the function f(x) 1 unit left.

Answer: 4,111.7 mm³

Step-by-step explanation:

You need to use this formula to calculate the volume of the square pyramid:

[tex]V=\frac{s^2h}{3}[/tex]

Where "s" is the lenght of any side of the square base and "h" is the height of the pyramid.

Find the height with the Pythagorean Theorem:

[tex]a^2=b^2+c^2[/tex]

Where "a" is the hypotenuse and "b" and "c" are the legs of the right triangle. Let be "c" the height of the pyramid.

You can identify in the figure that:

[tex]a=26mm\\\\b=\frac{23mm}{2}=11.5mm\\\\c=h[/tex]

Then, you can find the height:

[tex](26mm)^2=(11.5mm)^2+h^2\\\\h=\sqrt{(26mm)^2-(11.5mm)^2}\\\\h=23.318mm[/tex]

Then, knowing that:

[tex]s=23mm\\h=23.318mm[/tex]

You can calculate the volume:

 [tex]V=\frac{(23mm)^2(23.318mm)}{3}=4,111.7mm^3[/tex]

Answer:

B. 9.76 u²

Step-by-step explanation:

First calculate the area of the 60° wedge of the circle by calculating the area of the full circle and multiplying it by a fraction of 60°/360°:

[tex]A_{ABC}=\frac{60}{360}*\pi *r^{2}\\A_{ABC}=\frac{60}{360}*\pi *(6\sqrt{3})^{2}\\A_{ABC}=56.54[/tex]

Now calculate the the area of the white triangle in the wedge, by using a base length of [tex]3\sqrt{2}[/tex], and height:

[tex]h=\sqrt{(6\sqrt{3})^{2}-(3\sqrt{3})^{2}} \\h=9[/tex]

[tex]A_{TRI}=\frac{1}{2}*9*6\sqrt{3} \\A_{TRI}=27\sqrt{3} \\A_{TRI}=46.78[/tex]

Find the area of the red segment:

[tex]A_{ABC} -A_{TRI}\\=56.54-46.78\\=9.76[/tex]

The intersection of a cone and a plane parallel to its base is a circle. This is due to the concept of 'conic sections' that determine the shape based on the angle and position of the plane's intersection with the cone.

The cross section formed by the intersection of a cone and a plane parallel to the base of the cone is a circle. This shape is one of the conic sections, which also include the ellipse, parabola, and hyperbola. These shapes are formed depending on the angle and position at which a plane intersects with a cone.

A circle is formed when the cutting plane is parallel to the base of the cone. If the plane was at an angle, other shapes like an ellipse, parabola or hyperbola would be obtained. The word 'conic sections' comes from this geometric principle of intersecting a cone with a plane.

Answer:

A

Step-by-step explanation:

The solution to f(x) = g(x) occurs where the two graphs cross.  That's at the point (-2, -1).

Answer A.

To find where f(x) = g(x), set the two functions equal to each other and solve for 'x'. After some mathematical simplification and operations on both sides of the equation, we find that the solution is x = -1/9.

In mathematics, to find the solution for f(x) = g(x), you need to set the two equations equal to each other and solve for x. Here, we have f(x) = 2x and g(x) = 1/-3-x. Setting these two equations equal gives 2x = 1/-3-x.

To solve this equation, first, let's simplify the right hand side by multiplying both sides by -1 to make it easier to solve. Now the equation is -2x = 1/3+x.

Subtracting 'x' from both sides of the equation gives -3x = 1/3. Divide by -3 to solve for x so, x = -1/9. So, the solution for the equation f(x) = g(x) is x = -1/9.

Answer:

c on edge

Step-by-step explanation:

Answer:

Store #1 : 2x + 40

Store #2 : 3x + 36

he should buy his aquarium from store #1 because (2 * 5) + 40 = 50 and     (3 * 5) + 36 = 51, therefore it is cheaper at store #2 if he is buying 5 fish

To represent the cost of x fish and an aquarium at each store, we can set up a system of equations and solve them. By substituting the given information into the equations and simplifying, we can find the values of the variables. The solution represents the cost of an aquarium at each store. By comparing the total cost at each store, we can determine from which pet store Ronald should buy his aquarium if he wants 5 fish.

To write a system of equations to represent the cost of x fish and an aquarium at each store, let's assign variables to the cost of fish and the cost of an aquarium at each store.

Let:

x = number of fish

y = cost of an aquarium at the first store

z = cost of an aquarium at the second store

The first equation can be set up as: 2x + y = total cost at the first store

The second equation can be set up as: 3x + z = total cost at the second store

Solve this system to find the values of y and z.

Substitute the given information into the equations:

2x + y = 40 (equation 1)

3x + z = 36 (equation 2)

Multiply equation 1 by 3 and equation 2 by 2 to eliminate the y variable:

6x + 3y = 120

6x + 2z = 72

Subtract equation 2 from equation 1:

6x + 3y - (6x + 2z) = 120 - 72

6x - 6x + 3y - 2z = 48

y - 2z = 48

Now we have a system of equations:

y - 2z = 48

3x + z = 36

Solve this system using any method of your choice, such as substitution or elimination, to find the values of y and z.

Once you have the values of y and z, you can determine the cost of an aquarium at each store.

Compare the total cost at each store to decide from which pet store Ronald should buy his aquarium if he wants 5 fish.

Answer:

the answer 43.5 units²

Step-by-step explanation:

i took this in school and remember it hope it helped

1. The area of the figure is 42 units².

2. The area of the figure is 38 units²

The area of a figure is the extent of its 2D space, quantifying the region it occupies.

It's calculated using specific formulas based on the figure's geometric properties, such as length, width, and shape.

1. The figure can be splitted into 3

Area1 = 1/2bh

= 1/2 × 7 × 2

= 7units²

Area 2 = l × w

= 7 × 4 = 28 units²

Area 3 = 1/2bh

= 1/2 × 7 × 2

= 7 units²

Area of figure = 28+7+7

= 42 units²

2. The shape can be divided into a trapezoid and two equal triangles

area of Trapezoid = 1/2(a+b)h

= 1/2 ( 3+5)8

= 8 × 4

= 32 units²

area of triangle = 1/2bh

= 1/2 × 3 × 4

= 6 units²

area of the figure = 32 + 6

= 38 units²

Set up an equation to model this situation and solve:

2x=56

*Divide both sides by 2*

x=38
