Answer:

The measure of angle LMN is 68° ⇒ the last answer

Step-by-step explanation:

* Lets revise the properties of the rhombus

- The rhombus has 4 equal sides in length

- Every two opposite angles are equal in measure

- Every two adjacent angles are supplementary (their sum = 180°)

- The two diagonals bisect each other

- The two diagonals perpendicular to each other

- The two diagonals bisect the vertices angles

* Lets solve the problem

∵ LMNO is a rhombus

∴ ∠LMN and ∠MNO are adjacent angles

∴ ∠LMN and ∠MNO are supplementary

∴ m∠LMN + ∠MNO = 180°

∵ m∠MNO = 112°

∴ m∠LMN + 112° = 180° ⇒ subtract 112 from both sides

∴ m∠LMN = 68°

* The measure of angle LMN is 68°

Answer:

a) The sold games of Jezebel had the greatest spread.

b) The middle 50% of the games sold by Colin has the least spread.

c) Jezebel sold more games than colin.

Step-by-step explanation:

Range is sued to calculate the spread of the given data.

Range is given by:

[tex]Range=Max\ Value-Min\ Value[/tex]

So,

Part a)

For Collin:

Range=21-3=18

For Jezebel:

Range=26-5=21

Part b)

Middle 50% of the values will be the values between 1st quartile and 3rd quartile

So, to find quartiles:

For Colin:

=3,9,9,14,15,16,17,20,21

The median is 15.

The lower half is 3,9,9,14

Q1 = (9+9)/2= 18/2 = 9

The upper half is 16,17,20,21

Q3 = (17+20)/2= 37/2= 18.5

The middle 50% is first quartile subtracted from third quartile

So, the spread is:

18.5-9=9.5

For Jezebel:

4,5,8,10,11,14,20,20,26

The median is 11.

The lower half is 4,5,8,10

Q1 = (5+8)/2=13/2=6.5

The upper half is 14,20,20,26

Q3 = (20+20)/2=40/2=20

The middle 50% values' spread is:

20-6.5=13.5

Part c) The answer to part a tells us that Jezebels sold games have more spread than Colin's sold games. Similarly the answer of part b tells us that the spread of middle 50% values of Jezebel's sold games was more than the spread of middle 50% values of Colin's sold games ..

Answer:

There will be approx 283908 hits.

Step-by-step explanation:

A website had 342,000 hits in 2011.

This is a decline of 2.3% from the previous year.

Decline rate = 2.3% or 0.023

So, increase rate will be [tex]1-.023=0.977[/tex]

Time = [tex]2019-2011=8[/tex]

We can calculate the answer as:

[tex]342000\times(0.977)^{8}[/tex]

= [tex]342000\times0.83014[/tex]

= 283907.88 rounding to 283908.

Therefore, there will be approx 283908 hits.

Answer:

Step-by-step explanation:

The formula of a circumference:

[tex]C=2\pi r=d\pi[/tex]

r - radius

d - diameter

We have [tex]C=52\pi\ in[/tex].

Calculate the diameter using [tex]C=d\pi[/tex]:

[tex]d\pi=52\pi[/tex]                 divide both sides by π

[tex]d=52\ in[/tex]

-------------------------------------------------------------------------

If a circle inscribed in a square, then the diameter of a circle and a side of a square are congruent (have the same length).

We have the area of the square:

[tex]A=36\ mm^2[/tex]

The formula of an area of a square:

[tex]A=s^2[/tex]

s - side

Substitute:

[tex]s^2=36\to s=\sqrt{36}\\\\s=6\ mm[/tex]

The formula of a circumference [tex]C=d\pi[/tex]

d - diameter

d = s → d = 6 mm

Substitute:

[tex]C=6\pi\ mm[/tex]

The broken flagpole forms a right triangle, where the vertical leg is the piece still standing and the hypotenuse is the broken piece.

So, the original length is the sum of the hypotenuse and the vertical leg.

The hypotenuse can be found using the pythagorean theorem:

[tex]h=\sqrt{7^2+24^2}=25[/tex]

So, the flag was originally [tex]7+25=32[/tex] meters long.

The on second day and third day the amount of the helium gas will be left in the balloon gas will be 500 and 250 cubic cm respectively.

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have:

A helium balloon is filled with 1,000 cm3 of helium.

First day of the balloon has 1000 cubic cm helium gas

Each day, the balloon loses half its helium.

After second day the amount of helium gas = 1000/2 = 500 cubic cm

After third day, the amount of helium gas = 500/2 = 250 cubic cm

Thus, the on second day and third day the amount of the helium gas will be left in the balloon gas will be 500 and 250 cubic cm respectively.

Answer:6.5%

Step-by-step explanation:

There are 4, number three cards and 4 diamond cards in a deck of 52 cards. Divide 52 by 8.

Answer:

30.8% or 4/13

Step-by-step explanation:

There are 52 cards in a deck of cards.

There are 4 nines (4/52) and 13 (13/52) diamonds in a deck of cards.

When you add them together, you get 17/52. Then, you have to subtract the card that is both a nine and in a diamond suite, so you subtract -1 because there is only one card that fits both categories. You should have 16/52, which simplifies to 4/13 / 30.8%.

To find the answer, I used:

Volume = Length • Height • Width

Each book in box 1 has a volume of 132 inches^3 and there are 16 of them, so I multiplied 132 inches^3 by 16 and got a total volume of 2,112 inches^3 in box 1

Each book in box 2 has a volume of 30 inches^3 and there are 30 of them, so I multiplied 30 inches^3 by 30 and got a total volume of 900 inches^3 in box 2

2,112 inches^3 is greater than 900 inches^3 so box 1 should be more than twice as big as box 2

2112 cubic inches.

To determine which of the two boxes is larger, we need to calculate the volume of each box. For the first box, containing books each measuring 3/2 in by 8 in by 11 in, the volume of one book is calculated as:

For the second box, containing books each measuring 3/4 in by 5 in by 8 in, the volume of one book is calculated as:

Comparing the two totals, the second box, with a total volume of 4500 cubic inches, is larger than the first box, which has a total volume of 2112 cubic inches. Hence, we know that the second box is larger because it has a greater total volume.

Answer:

24 Days

Step-by-step explanation:

The smallest common multiple of 6 and 8 is 24. Therefore, both girls will bring cheese and crackers for lunch on the same day 24 days from today.

This question is about finding the least common multiple (LCM) of the two numbers. Sandra brings cheese and crackers for lunch every 6 days and Lily every 8 days. The first step in solving this problem is to list the first few multiples of each number to find the smallest number that both numbers have in common.

So, for Sandra, the multiples of 6 are 6, 12, 18, 24, 30, 36, etc. And for Lily, the multiples of 8 are 8, 16, 24, 32, 40, etc. The least common multiple of 6 and 8 is 24.

Therefore, it will be 24 days before both Sandra and Lily bring cheese and crackers for lunch on the same day again.

Answer:

([tex]\frac{27}{2}[/tex], 4 )

Step-by-step explanation:

Use the midpoint formula

midpoint = [[tex]\frac{1}{2}[/tex](x₁ + x₂), [tex]\frac{1}{2}[/tex](y₁ + y₂ ) ]

with (x₁, y₁ ) = (14, - 6) and (x₂, y₂ ) = (13, 14), hence

[[tex]\frac{1}{2}[/tex](14 + 13), [tex]\frac{1}{2}[/tex](- 6 + 14) ]

= ([tex]\frac{27}{2}[/tex], 4)

The solution to the system of equations y=4x+6 and y=2x-4 is (-5, -14) by solving the equations simultaneously.

The solution to the system of equations y = 4x + 6 and y = 2x - 4 is found by setting the two equations equal to each other since they both equal y. This gives us 4x + 6 = 2x - 4. By subtracting 2x from both sides, we get 2x + 6 = -4. Subtracting 6 from both sides gives us 2x = -10. Dividing both sides by 2 gives us x = -5. Substitute x = -5 into either original equation to find y. Let's use the first equation: y = 4(-5) + 6, which simplifies to y = -20 + 6, and finally y = -14. Hence, the solution to the system of equations is (-5, -14).

Answer:

[tex]Area=1,325\ yd^2\\Perimeter=204\ yd[/tex]

Step-by-step explanation:

You can use the following formula to calculate the area of the triangle:

[tex]A=\frac{bh}{2}[/tex]

Where "b" is the base and "h" is the height.

You can observe in the figure that:

[tex]b=53\ yd\\h=50\ yd[/tex]

Then, the area is:

[tex]A=\frac{(53\ yd)(50\ yd)}{2}=1,325\ yd^2[/tex]

To find the perimeter you must add the lenght of each side of the triangle. Then, this is:

[tex]P=97\ yd+53\ yd+54\ yd\\\\P=204\ yd[/tex]

Answer:

Well I think it is A because domain is the x values.

Step-by-step explanation:

So when you plug this in your calculator (mine is a ti-84 plus ce) you would hit graph. After it graphs it press Zoom, 0 to center it then press 2nd, trace which pulls up parabola menu's. Press 0 and find the left bound, right bound and then press enter which would give you x values of 2.9375 < t< 6

At the same time I don't know if this is right. I never really excelled at parabolas just trying to help.

Check the picture below.

so the domain will be the values that "x" gets, now, the maximum height of the ball is when it reaches the vertex or U-turn up above, well, what is the x-coordinate anyway?

[tex]\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ f(t)=\stackrel{\stackrel{a}{\downarrow }}{-16}t^2\stackrel{\stackrel{b}{\downarrow }}{+94}t\stackrel{\stackrel{c}{\downarrow }}{+12} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right) \\\\\\ \left( -\cfrac{94}{2(-16),}\qquad \qquad \right)\implies \left( \cfrac{487}{16},\qquad \qquad \right)\implies (2.9375,\qquad \qquad )[/tex]

so then x = 2.9375 at the vertex, now, what is "x" when it hits the ground? recall y = 0 at that instant.

[tex]\bf \stackrel{f(t)}{0}=-16t^2+94t+12\implies 0=-2(8t^2-47t-6) \\\\\\ 0=(8t+1)(t-6)\implies t= \begin{cases} \boxed{6}\\ \begin{matrix} -\frac{1}{8} \\[-0.5em]\cline{1-1}\\[-5pt]\end{matrix} \end{cases}[/tex]

so then, the values for "x" or namely the domain from the vertex till the ball hits the ground is 2.9375 < t < 6.

3 houses have all pink, blue, and yellow.

Answer:

The answer is 3 houses.

Step-by-step explanation:

This question is based on the Least Common Multiple (LCM) method. We will find the LCM of the numbers 4, 6 and 8.

4 = 2 x 2 = [tex]2^{2}[/tex]

6 = 2 x 3 = 2 x 3

8 = 2 x 2 x 2 = [tex]2^{3}[/tex]

So, LCM is = [tex]2^{3}\times3=24[/tex]

Therefore, at every 24th houses, we will find all three trolls colors.

And 24 is the number of houses we will find all color trolls. Then in a group of 75 houses, it will occur thrice and at every 24th place. Means. 3 houses will have all color trolls.

Answer:

2(x - 10)(x + 10)

Step-by-step explanation:

Given

2x² - 200 ← factor out 2 from each term

= 2(x² - 100) ← x² - 100 is a difference of squares and factors as

x² - 100 = x² - 10² = (x - 10)(x + 10), hence

2x² - 200 = 2(x - 10)(x + 10)

Answer:

Step-by-step explanation:

If your equation is [tex]2x^2-200[/tex] and you're to factor it, the first thing you do is set the expression equal to 0 so you can solve for x.

[tex]2x^2-200=0[/tex]

There's a couple of different ways in which to approach this.  You can factor out a 2:

[tex]2(x^2-100)=0[/tex]

and solve it from there.  The Zero Product Property says that if the equation is equal to 0, then either 2 has to equal 0 or [tex]x^2-100[/tex] has to equal 0.  We know that 2 does not equal 0, so [tex]x^2-100=0[/tex]

Add 100 to both sides in the equation:

[tex]x^2=100[/tex]

and then take the square root of both sides.  Because this is a second degree polynomial, we expect to have 2 solutions, and we do.  Don't forget that when you take the square root of a number you have to alow for both the positive and the negative of the result.  Our factored form of the given equation then is that x = 10 and x = -10.

Answer:

Step-by-step explanation:

1. The option is (A) mean = –25; median = –26.5; mode = –28; range = 40.

2. The option is (C) 13; 17.6; 20.

The median is the value that splits the mathematical numbers or expressions in the half. The median value is the middle number of data points. to find the median first arrange the data points in ascending order.

To find the mean, median, mode, and range of the data set, we first need to arrange the data in order:

–46, –39, –28, –28, –25, –17, –11, –6

Mean: To find the mean, we add up all the values and divide by the total number of values:

Mean = (-46 + -39 + -28 + -28 + -25 + -17 + -11 + -6) / 8

Mean = -25

Median: To find the median, we need to find the middle value of the data set.

Since there are 8 values, the median is the average of the 4th and 5th values:

Median = (-28 + -25) / 2

Median = -26.5

Mode: The mode is the value that appears most frequently in the data set. In this case, the mode is –28, since it appears twice and no other value appears more than once.

Range: To find the range, we subtract the smallest value from the largest value:

Range = -6 - (-46)

Range = 40

Therefore, the answer is (A) mean = –25; median = –26.5; mode = –28; range = 40.

2.

A. The outlier in the data set is 37, since it is much larger than the other values.

B. To find the mean with the outlier, we add up all the values and divide by the total number of values:

Mean = (21 + 13 + 13 + 37 + 13 + 23 + 25 + 15) / 8

Mean = 17.6

C. To find the mean without the outlier, we need to exclude the value 37 and then calculate the mean using the remaining values:

Mean = (21 + 13 + 13 + 13 + 23 + 25 + 15) / 7

Mean = 17.6

Therefore, the answer is (C) 13; 17.6; 20.
