Answer:

After 7 days there are the same number of both calendars left in the store

Step-by-step explanation:

Let x be defined by the number of days,

41 total, 3 Ocean calendars sell each day

48 total, 4 Space calendars sell each day

expression: 41 - 3x = 48 - 4x

- we set them equal to find when x amount days are the same for both calendars

- we subtract due to selling each calendars

solving:

41 - 3x = 48 - 4x                      

add 4x to both sides, trying to get like terms on the same side

41 - 3x + 4x = 48 - 4x + 4x

41 + x = 48

now subtracts 41 from both sides to get x alone

41 - 41 + x = 48 - 41

x = 7

The surface area of the regular pyramid is 770 [tex]m^{2}[/tex]

Option B. 770  [tex]m^{2}[/tex] is the answer.

The surface area of a pyramid is a measure of the total area that is occupied by all its faces.

We have to find the surface area of the regular pyramid with a base of 6 sides (hexagonal base).

Surface area of pyramid = area of triangles at the lateral sides + area of base (Hexagon)

Surface area of hexagonal base,

[tex]\frac{1}{2}*(Apothem)*(Perimeter) \\= \frac{1}{2}*(6\sqrt{3} )*(72)\\=216\sqrt{3}[/tex]

Surface area of triangular sides = 6 * 1/2 * b *h

                                                       = 3 * 12 *11

                                                       = 396  [tex]m^{2}[/tex]

Now total surface area = 216√3 + 396

                                        = 374.112 + 396

                                        = 770.112

                                        ≈ 770 [tex]m^{2}[/tex]

The surface area of the regular pyramid is 770 [tex]m^{2}[/tex]

Option B.  770 [tex]m^{2}[/tex]

Step-by-step explanation:

Substitution

Answer:

5/3 or 1 2/3 (also, there is no graph so I had to do subsitution)

Step-by-step explanation:

If we substitute, we get 3 = 3x-2. We add 2 to both sides and get 5 = 3x

We divide 3 from both sides and get 5/3 = x or x = 5/3

It is biased. The sample of people at the ball park is not representative of star city’s residents.

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

In this problem, we have that only one group is sampled, that is, the people that went to the ballgame, hence the sample is not representative and the correct option is given by:

The expressions which are equivalent to the trigonometric function cos(theta) are cos(2pi+theta) and cos(-theta)

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

The given trigonometric expressions is,

[tex]f(\theta)=\cos\theta[/tex]

The cosine function is the periodic function. The function repeats itself after the 2π. Thus,

[tex]f(\theta)=\cos\theta\\f(\theta)=\cos(2\pi+\theta)[/tex]

The cosine function is an even function. Thus,

[tex]f(\theta)=\cos\theta\\f(\theta)=\cos(-\theta)[/tex]

Thus, the expressions which are equivalent to the trigonometric function cos(theta) are cos(2pi+theta) and cos(-theta)

Answer:

[tex](x + 4)^{2} + (y + 1)^{2} = 29[/tex].

Step-by-step explanation:

The equation of a circle of radius [tex]r[/tex] and center [tex](a,\, b)[/tex] is:

[tex](x - a)^{2} + (y - b)^{2} = r^{2}[/tex].

In this question, it is given that the center is [tex](-4,\, -1)[/tex], such that [tex]a = (-4)[/tex] while [tex]b = (-1)[/tex].

The radius of this circle could be found as the distance between the center of this circle, [tex](-4,\, -1)[/tex], and any point on the circle- such as [tex](1,\, -3)[/tex]. Using the distance formula, the radius of this circle would be:

[tex]\begin{aligned}r &= \sqrt{((-4) - 1)^{2} + ((-1) - (-3))^{2}} \\ &= \sqrt{29}\end{aligned}[/tex].

Therefore, the equation of this circle would be:

[tex](x - (-4))^{2} + (y - (-1))^{2} = (\sqrt{29})^{2}[/tex].

Simplify to obtain:

[tex](x + 4)^{2} + (y + 1)^{2} = 29[/tex].

Step-by-step explanation:

The amount of money that Jordan will earn at the end of 10 years = $12,587.5

The principal amount invested(P) = $9,500

The annual compounded daily interest rate(R) of the account = 3.25%

The time given (T) = 10 years

Simple interest (SI) = P×T × R/100

SI = 9,500×10×3.25/100

SI= 308750/100

SI= $3087.50

Therefore the total amount that would be in the account after 10 years = $9,500 + $3,087.50

Answer:

22

Step-by-step explanation:

the pattern here is to divide the previous number by 3

the first number is 15, divided by 3 to give you the second number:5 ,the second number divided by 3 gives us 5/3

using that principle the first six terms are :

15, 3, 5/3 , 5/9, 5/27, 5/81

(just multiply the denominator by 3)

adding we have

[tex]15 + 5 + \frac{5}{3} + \frac{5}{9} + \frac{5}{27} + \frac{5}{81} = \frac{1820}{81} [/tex]

Answer:

Distributive property

Step-by-step explanation:

The distributive property states that if you have an equation inside parenthesis with a number outside, you should multiply the number with each of the member inside the parenthesis. So lets say you have 3(1-4), you are not going to add the members together after multiplication, you are gonna apply the mathematical equation that was available in the first place, so u will multiply 3×1 - 3×4, this applies to any situation you have. Let’s say you have 3+(4-2), here you cannot multiply the 3 by any of the parenthesis, since there is an addition sign right before it, we conclude that the number should be right beside the parenthesis bcz parenthesis are like multiplication signs. So you have 3(4-2), first step you do is multiply each of the number inside by the number outside, and you will get the subtraction sign in the middle of them. It will look like this 3×4 -3×2, u multiply them all together, with the multiplication first and subtraction at last.

Step-by-step explanation:

135+k=180(sum of angles on a straight line)

k=180-135

k=45

so now u can use k to solve for x

k+9x is also on a straight line

so k+9x=180

we know k so substitute the value in the equation

45+9x=180

9x=180-45

9x=135

Valentina got 4 times more hair cut off than her sister

Step-by-step explanation:

1 4 4

- × - = -

5 1 5

Valentina got 4 times more hair taken off than her sister, as the ratio between them is 4:1.

The ratio is the simplest form of a fraction involving two quantities determining each other. It is written as a:b, read as "a is to b", and functions as a/b.

In the question, we are informed that Valentina and her sister went together to get haircuts. Valentina got 4/5 of an inch cut off and her sister got 1/5 of an inch cut off.

We are asked to find a comparison between the two.

To find the comparison, we will find the ratio of the haircut Valentina got to that of what her sister got.

Therefore, ratio = (4/5):(1/5) = (4/5)/(1/5) = 4.

Therefore, Valentina got 4 times more hair taken off than her sister.

Answer:568.99 is what I calculated

Step-by-step explanation:

The correct classification for the angle JML is an acute angle.

An acute angle has a measure, or it's smaller, than a right angle.

An acute angle has a measure less than 90 degrees.

Therefore,

let's find the measure of ∠JML

Hence,

∠JML = ∠JMK + ∠KML

∠KML = 180 - 132 = 48 degrees.

Therefore,

∠JML = 41 + 48 = 89 degrees.

Looking at the given points we know that it is going to be a triangle because it only have 3 points.  Therefore the figure is a triangle and the area formula would be [tex]A=\frac{1}{2}*b*h[/tex].

You can look at the attached graph and what we see is that our height of the triangle is from [tex]y=-3[/tex] to [tex]y=4[/tex] which means that our height is 7 units high.  We can also see that our base starts at [tex]x=-4[/tex] and ends at [tex]x=4[/tex] making us have a base of 8 units.

We then plug in the values and solve

[tex]A = \frac{1}{2}*7\ units * 8\ units[/tex]

[tex]A = \frac{1}{2}*56\ units^2[/tex]

[tex]A = 28\ units^2[/tex]
