What value of r makes {2r+3}{5}={4r-3}{7}
true?

9514 1404 393

Answer:

  14.01, 493, 87

Step-by-step explanation:

Subtracting 28 from both sides tells you the range of values you need to be looking at.

  28 + x > 42

  x > 14

Any values more than 14 will make the inequality true. Three of them are ...

Answer:

x=5 and y=-2

Step-by-step explanation:

3x+5y=5

-(7x+5y=25)

-4x=-20

x=5

plug 5 into one of the equations. 3(5)+5y=5

y= -2

Answer:

the y-intercept, b, is 7

Step-by-step explanation:

Compare the given y = -3.1 +7 to y = mx + b.  I must assume that you meant

y = -3.1x +7.  It becomes evident that the slope, m, is -3.1 and the y-intercept, b, is 7.

Hey there!

Prime numbers are basically only approximately 2 FACTORS... 1 & that particular number

3 is PRIME because the only factors it has is 1 & 3 (so we can eliminate this as your possible answer)

29 is PRIME because it has 1 & 29 as its factors (we can eliminate this as your possible answer)

71 is PRIME because it has 1 & 71 as its factors as well! (So we can eliminate as your possible answer)

This leads Option B as your answer

Good luck on your assignment and enjoy your day!

Answer:

The value of n = 4 and  

The value of x = [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

Method I:

As given, 12x -20=n (3x-5)      .........(1)

Firstly , take 12x - 20

As 12x - 20 can be written as 4(3x - 5)

∴ equation (1) becomes

4(3x - 5) = n (3x-5)

Divide the equation by (3x-5) , we get

4 = n

Method II:

As given, 12x -20=n (3x-5)

⇒12x - 20 = 3nx - 5n

⇒12x - 3nx = 20 - 5n

⇒3x(4 - n) = 5( 4 - n)

Divide the equation by (4-n) , we get

3x = 5

⇒ x = [tex]\frac{5}{3}[/tex]

∴ we get

n = 4 and  x = [tex]\frac{5}{3}[/tex]

Now, check that value of n and x satisfies the equation or not

12([tex]\frac{5}{3}[/tex]) - 20 = 4( 3([tex]\frac{5}{3}[/tex]) - 5)

⇒4(5) - 20 = 4(5 - 5)

⇒20 - 20 = 4(0)

⇒ 0 = 0

Hence , we get

The values of x and n satisfies the equation

so, we get

n = 4 and  x = [tex]\frac{5}{3}[/tex]

Answer:

113.04

Step-by-step explanation:

The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex]

Given that,

Deon is playing fetch with his dog with a toy that is shaped like a circle,

The circumference of the sculpture is 12π inches.

We have to determine,

Which measurement is closest to the area of the toy in square inches.

According to the question,

Circumference of the circle = [tex]2\pi r[/tex]

Where, circumference = [tex]12\pi[/tex]

Then,

[tex]12\pi =2\pi r \\\\r = \dfrac{12\pi }{2\pi }\\\\r = 6\ inches[/tex]

Therefore,

Deon is playing fetch with his dog with a toy that is shaped like a circle.

Area of the circle = [tex]\pi r^{2}[/tex]

Where, r = 6inches

Then,

Area of the circle is given by,

[tex]= \pi r ^{2}\\\\= 3.14 \times (6)^{2}\\\\= 3.14 \times 36\\\\= 113.04\ inches^{2}[/tex]

Hence, The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex].

Answer and Step-by-step explanation:

Hello!

You are told to round the number to the nearest whole number.

That means if the decimal is lower than 5 in the tenths place, the number would round down, and if the decimal is equal to or higher than 5 in the tenths place, the number would round up.

[tex]5\frac{5}{6}[/tex] is equal to 5.833. The number 8 is greater than 5, so the number rounds up to 6.

[tex]6\frac{1}{9}[/tex] is equal to 6.111. The number 1 is less than 5, so the number rounds down to 6.

Now we have the equation n - 6 = 6.

We solve for n.

Add 6 to both sides.

n  =  12

n is equal to 12.

The table representing the relative frequencies by rows would be:

                    King Bed     Queen Bed

Mountain 0.58       0.42

Ocean         0.38             0.62

The table representing the relative frequencies by columns would be:

                King Bed Queen Bed

Mountain      0.68             0.47

Ocean       0.32             0.53

Relative frequency is a statistical term that describes the proportion or percentage of times that an event or value occurs within a dataset or sample.

It is calculated by dividing the number of times the event occurs by the total number of observations in the dataset or sample.

We have,

To find the relative frequencies of this data by rows or by columns, we need to divide each count by the total number of rooms occupied. The total number of rooms occupied is:

25 + 18 + 12 + 20 = 75

To find the relative frequencies by rows, we divide each count by the total for that row:

For Mountain View rooms:

King Bed: 25/(25+18) ≈ 0.58

Queen Bed: 18/(25+18) ≈ 0.42

For Ocean View rooms:

King Bed: 12/(12+20) ≈ 0.38

Queen Bed: 20/(12+20) ≈ 0.62

The table representing the relative frequencies by rows would be:

                    King Bed     Queen Bed

Mountain 0.58       0.42

Ocean         0.38             0.62

To find the relative frequencies by columns, we divide each count by the total for that column:

For King Bedrooms:

Mountain View: 25/(25+12) ≈ 0.68

Ocean View: 12/(12+20) ≈ 0.38

For Queen Bedrooms:

Mountain View: 18/(18+20) ≈ 0.47

Ocean View: 20/(18+20) ≈ 0.53

The table representing the relative frequencies by columns would be:

                King Bed Queen Bed

Mountain      0.68             0.47

Ocean       0.32             0.53

Note that we round the relative frequencies to the nearest hundredth.

Thus,

The table representing the relative frequencies by rows and columns is given above.
