The perimeter of a square piece of cardboard with each side measuring 7/12 meter is found by using the formula P = 4a. After calculation, the perimeter is 2 1/3 meters.

The question asks us to calculate the perimeter of a square piece of cardboard with each side measuring 7/12 meter. To find the perimeter of a square, we use the formula P = 4a, where 'P' is the perimeter and 'a' is the length of one side. Since all sides of a square are equal, we simply multiply the length of one side by 4.

In this case, the length of one side (a) is 7/12 meter, so the perimeter (P) would be:

P = 4 × (7/12 meter)
P = (4 × 7/12) meter
P = 28/12 meter
P = 7/3 meter (after simplifying)
P = 2 1/3 meters (in mixed numbers)

Therefore, the perimeter of the square piece of cardboard is 2 1/3 meters.

For this case we have the following system of two equations with two unknowns:

[tex]-2x + y + 6 = 0\\2x + y-8 = 0[/tex]

Adding both equations we have to eliminate the variable "x":

[tex]y + y + 6-8 = 0[/tex]

Adding common terms, keeping in mind that different signs are subtracted and the sign of the major is placed:

[tex]2y-2 = 0\\2y = 2[/tex]

Step-by-step explanation:

Answer:

domain is set of all real number except 4/5

Step-by-step explanation:

[tex]f(x)= \frac{x-3}{x}[/tex]

[tex]g(x)=5x-4[/tex]

Now we find (fºg)(x)

(fºg)(x)=f(g(x))

We plug in g(x) inside in f(x)

[tex]f(g(x))=f(5x-4)= \frac{(5x-4)-3}{5x-4}[/tex]

Now simplify the numerator

[tex]f(g(x))=\frac{(5x-4)-3}{5x-4}=\frac{5x-7}{5x-4}[/tex]

To find out domain we set the denominator =0 and solve for x

[tex]5x-4=0[/tex]

Add 4 on both sides

[tex]5x=4[/tex]

Divide both sides by 5

[tex]x=\frac{4}{5}[/tex]

So domain is set of all real number except 4/5

Answer: 25 heads 25 tails

Step-by-step explanation: you would have a 50/50 chance to get heads or tails so sence there are 2 sides you would get 25 heads and 25 tails

Answer: 25 Times Head And 25 Time Tails

Step-by-step explanation: If you flip a dime in the air and if you flip it 50 times, there is an equally likely chance of flipping heads or tails. Equally likely chance means 50%. Ofcourse, it's not very likely that it would be exactly 25 times for heads and tails. Therefore, if I flipped a dime 50 times I would expect it to land  near 25 times on heads and 25 times around tails.

Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value. A low standard deviation means that most of the numbers are close to the average. A high standard deviation means that the numbers are more spread out.

It is a measure of the average distance between the values of the data in the set and the mean. A low standard deviation indicates that the data points tend to be very close to the mean; a high standard deviation indicates that the data points are spread out over a large range of values.

So, good standard deviation is 5 = Very Good, 4 = Good, 3 = Average, 2 = Poor, 1 = Very Poor, The mean score is 2.8 and the standard deviation is 0.54.

Step-by-step explanation:

For this case we have that the figure shown is composed of three triangles and a square. By definition, the area of a triangle is given by:

[tex]A = \frac {1} {2} b * h[/tex]

Where:

b: It's the base

h: It's the height

We have 3 triangles, then the sum of their areas will be:

[tex]A = \frac {1} {2} (9 * 3.5) + \frac {1} {2} (2 * 2) + \frac {1} {2} (5 * 2)\\A = 15.75 + 2 + 5\\A = 22.75 \ units ^ 2[/tex]

On the other hand, the area of a square is given by:

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

Where:

l: It's the side of the square

According to the figure we have:

[tex]A = 2 ^ 2\\A = 4 \ units ^ 2[/tex]

So, the total area is:

[tex]A_ {t} = 22.75 + 4\\A_ {t} = 26.75 \ units ^ 2[/tex]

Answer:

[tex]A_ {t} = 26.75 \ units ^ 2[/tex]

the answer is Chelsea spent more than $12.75

Option 4, 'Chelsea spent more than $12.75,' matches the given inequality d > 12.75, as it directly corresponds with the 'greater than' symbol in the inequality. So, option 4 is correct.

The inequality d > 12.75 translates to "d is greater than 12.75." Looking at the options provided, we can find a situation that matches the inequality by understanding the meaning of the inequality symbol. Option 4, which says "Chelsea spent more than $12.75," directly corresponds to the inequality given. In this scenario, the amount Chelsea spent (d) is greater than $12.75, which is exactly what the inequality d > 12.75 signifies.

The slope is -2/5; and the y-intercept is  -1/3

Step-by-step explanation:

Slope = (-13/30 + 1/30) / (1/4 + 3/4)

= (-12/30) / ( 4/4)

= - 2/5

Slope intercept form: y = mx + b, where b = y-intercept

b = y - mx

b = (-3/5) - (-2/5)(2/3)

b = -3/5 + 4/15

b = -9/15 + 4/15

b = -5/15

b = -1/3

Answer

Slope = -2/5; y-intercept = -1/3

The slope and the y-intercept of the linear function is;

Option A; slope is -2/5 and y-intercept is -1/3

      m = (y2 - y1)/(x2 - x1)

Let's make use of the first 2 coordinates to get the slope;

x1 = -3/4

x2 = -1/2

y1 = -1/30

y2 = -2/15

m = (-2/15 + 1/30)/(-1/2 + 3/4)

m = (-1/10)/(1/4)

m = -2/5

We know equation of a line in slope intercept form is;

y = mx + c

where m is slope and c is y-intercept

-1/30 = (-2/5)(-3/4) + c

-1/30 - 3/10 = c

c = -1/3

Thus, y-intercept is -1/3 and slope is -2/5

The volume is V=324.

We substitute the values in to the formula and solve for l.

[tex]324 = \frac{1}{3} {l}^{2} \times 12[/tex]

[tex]324 = 1 {l}^{2} [/tex]

[tex] {l}^{2} = \frac{324}{4} [/tex]

Answer:

The mean will stay the same.

The standard deviation will decrease.

Step-by-step explanation:

For the 5 cards, she has received, the mean will be:

μ=(∑x)/n

=125/5

=25

The mean is 25 and the standard deviation is 10.  

σ=10

If a new card is received with $25, then the sum will be $150  

So the new mean will be:

μ'=(∑x)/n

=150/6

=25

And the new standard deviation will be:  

σ'= 9.12

We can clearly see that  

μ= μ'

and

σ> σ'

So the mean will remain the same and standard deviation will decrease. .

EXPLANATION

The volume of a cylinder is calculated using the formula

[tex]V=\pi {r}^{2} h[/tex]

From the question, the volume was given as 540π ft³ .

The height is given as 15 ft.

We substitute the values to obtain:

[tex]540\pi=\pi {r}^{2} \times 15[/tex]

This implies that;

[tex] {r}^{2} = \frac{540\pi}{15\pi} [/tex]

We simplify to get;

[tex] {r}^{2}=36[/tex]

Take positive square root to obtain:

[tex]r = \sqrt{36} [/tex]

[tex]r = 6ft[/tex]

The diameter is twice the radius.

Hence the diameter is 12ft

The answer is:

The diameter of the cylinder is equal to 12 feet.

Why?

To find the diameter of the cylinder we need to use the formula to calculate its volume.

So,  we have:

[tex]Volume=\pi *r^{2}*h[/tex]

We are given the following dimensions of the cylinder:

[tex]Volume=540\pift^{3}\\\\Height=15ft^{3}[/tex]

Now, using substituting and isolating the radius in order to find the diameter, we have:

[tex]Volume=\pi *r^{2}*h\\\\r^{2}=\frac{Volume}{\pi *h} \\\\r=\sqrt{\frac{Volume}{\pi *h} }[/tex]

Therefore, we have:

[tex]r=\sqrt{\frac{Volume}{\pi *h}}\\\\r=\sqrt{\frac{540\pi ft^{3}}{\pi *15ft}}\\\\r=\sqrt{36ft^{2} }=6ft[/tex]

We know the radius, then, calculating the diameter we have:

[tex]diameter=2*radius=2*6ft=12ft[/tex]

Hence, we have that the diameter of the cylinder is equal to 12 feet.

Answer:

1)m=9ft and n=10ft

2) p=10cm and r=18cm

3) s=4mi and t=8mi

Step-by-step explanation:

1)

Finding 3rd angle:

F= 180-(90+60)

 = 180-150

 =30

Now using law of sines to find sides m and n

m/sinD = 5/sinF

m= sin60(5/sin30)

  = 8.66

   = 9

n/sinE= 5/sin30

n= sin90(5/sin30)

  = 10

hence m=9ft and n=10ft

2)

Finding 3rd angle:

F= 180-(90+60)

 = 180-150

 =30

Now using law of sines to find sides p and r

p/sinF = 21/sinE

p= sin30(21/sin90)

  = 10.5

   = 10

r/sinD= 21/sin90

r= sin60(21/sin90)

  = 18.18

  =18

hence p=10cm and r=18cm

3)

Finding 3rd angle:

F= 180-(90+60)

 = 180-150

 =30

Now using law of sines to find sides s and t

s/sinF = 3√6/sinD

s= sin30(3√6/sin60)

  = 4.24

   = 4

t/sinE= 3√6/sinD

t= sin90(3√6/sin60)

  = 8.48

  = 8

hence s=4mi and t=8mi !
