Chris bought  [tex]8[/tex]  Oranges.

Reasoning is the process of using existing knowledge to draw conclusions, make predictions, or construct explanations.

We have,

Chris and Pat bought [tex]48[/tex] oranges.

Let,

Oranges bought by Pat [tex]= x[/tex]

Oranges bought by Chris [tex]= y[/tex]

Now,

According to the question;

As  Pat bought five times as many as bought by Chris.

i.e.

[tex]x=5y[/tex]     [tex]........(i)[/tex]

And,

Chris and Pat bought [tex]48[/tex] oranges.

i.e.

[tex]x+y=48[/tex]     [tex]........(ii)[/tex]

Now,

Substituting value of [tex]x[/tex] from equation [tex](i)[/tex] in equation [tex](ii)[/tex];

We get,

[tex]5y+y=48[/tex]

[tex]6y=48[/tex]

[tex]y=8[/tex]

Now,

Substituting value of [tex]y[/tex]  in equation [tex](i)[/tex];

[tex]x=5y[/tex]

[tex]x=5*8[/tex]

[tex]x=40[/tex]

Hence, we can say that Chris bought  [tex]8[/tex]  Oranges and Pat bought [tex]40[/tex] Oranges.

Answer:

2^(6-3) = 2^3 = 8

Step-by-step explanation:

To simplify radical 64/8

We will express 64 and 8 in powers of 2

64 = 2×2×2×2×2×2= 2^6

8 = 2×2×2=2^3

From the law of indices,

a^5 / a^3 = a^ (5-3) = a^2

Applying this law of indices to the given radical,

64/8 = 2^6/ 2^3

= 2^(6-3)

= 2^3 = 8

Also, we can try another way. since

64 = 2×2×2×2×2×2= 2^6

8 = 2×2×2=2^3

64/8 = 2×2×2×2×2×2 / 2×2×2

2×2×2 cancels out 2×2×2 and

It remains 2×2×2 = 8

So which ever way we do it,

radical 64/8 simplified is 2^3 = 8

or 1st answer

Step-by-step explanation:

Option (C) √3 + 8.486 is an irrational number.

An irrational number is a type of real number which cannot be represented as a simple fraction. It cannot be expressed in the form of a ratio. Those real numbers that are not rational numbers are known as irrational numbers.

For the given situation,

We need to check the options, that is irrational.

Option A: 7.51... x -4

⇒ [tex](7.51 ) (-4)[/tex]

We can express this as fraction. So it is not an irrational number.

Option B: root 16 + 3/4

⇒ [tex]\sqrt{16} +\frac{3}{4}[/tex]

⇒ [tex]4+\frac{3}{4}[/tex]

We can express this as fraction. So it is not an irrational number.

Option C: root 3 + 8.486

⇒ [tex]\sqrt{3} +8.486[/tex]

⇒ [tex]\sqrt{3}[/tex]  is an irrational number, so the sum is also an irrational number.

Option D: 8 2/3 × 17.75

⇒ [tex](8\frac{2}{3})(17.75)[/tex]

We can express this as fraction. So it is not an irrational number.

Hence we can conclude that option (C) √3 + 8.486 an irrational number.

Answer:

[tex]3+\frac{3}{4}x\geq 12[/tex]

Step-by-step explanation:

Given,

The number of hour he already practiced in this week = 3,

Also, she practices for three fourth of an hour each session,

If x be the number of remaining session,

So, the additional number of hours he practiced in this week = [tex]\frac{3x}{4}[/tex]

Thus, the total number of hours he practiced in this week = [tex]3+\frac{3x}{4}[/tex]

According to the question,

Total number of hours ≥ 12 hours

[tex]\implies 3+\frac{3x}{4}\geq 12[/tex]

Which is the required inequality.

The length of the picture frame is 17 inches, which is found by substituting the given width and perimeter into the perimeter formula and solving for the length.

The question asks to calculate the length of a picture frame using the perimeter formula P = 2l + 2w, where P stands for the perimeter, l is the length, and w is the width. Given that the width (w) is 19 inches and the perimeter (P) is 72 inches, we can substitute these values into the formula:

P = 2l + 2w

72 = 2l + 2(19)

72 = 2l + 38

2l = 72 - 38

2l = 34

l = 34 / 2

l = 17 inches

So, the length (l) of the frame is 17 inches.

The value of kj is 15.

It is required to find the value of kj.

The midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.

Given that:

k is the midpoint of hj and hk.

hk=x+6

hj=4x-6

We know that midpoint cuts the segment hj in 2 equal parts that means hk=kj and hk+kj=hj

hk+hk=hj

2hk=hj

2hk=hj

2 (x+6)=(4x-6)

2x+12=4x-6

12+6=4x-2x

18=2x

Divide 2 on both sides, we get

18/2=2x/2

9=x

hk=kj=x+6=(9)+6=15

kj=15

Therefore, the value of kj is 15.

The equation of a line passing through (5, -2) and (-3, 4) is given by :-

[tex](y-(-2))=\dfrac{4-(-2)}{-3-5}(x-5)\\\\\Rightarrow\ y+2=\dfrac{6}{-8}(x-5)\\\\\Rightarrow\ y+2=\dfrac{-3}{4}(x-5)\\\\\Rightarrow\ 4(y+2)=-3(x-5)\\\\\Rightarrow\ 4y+8=-3x+15\\\\\Rightarrow\ 4y=-3x-7[/tex]

To calculate the number of gallons Peter needs, multiply the surface area of one side of the wall (225 ft2) by 2 for both sides, and then by 2 again for two coats, totaling 900 ft2. Then divide 900 ft2 by the coverage per gallon x to get the expression 900 / x.

To determine the number of gallons of paint Peter needs, we must first calculate the total paintable surface for both the inside and outside of the walls and then factor in the two coats of paint. Peter has 5 walls, with each side having 45 ft2 of paintable surface, so the total paintable surface for one side is 5 walls  imes 45 ft2/wall = 225 ft2. Since he wants to paint both sides, we double this to get 450 ft2. For two coats, we need to double this again, resulting in 900 ft2. Now, if a gallon of paint covers x ft2, the number of gallons needed is total square footage divided by coverage per gallon, which is 900 ft2 / x ft2/gallon.

Therefore, the expression to represent the number of gallons Peter needs is 900 / x.

The solutions of the above system of equations is x = 3 and y = -7 and the graph of above system of equations is as shown below.

"It is a finite set of equations for which we find the solution."

For given question,

We have been given a system of equations.

4x +2y = -2                     ................(i)

x - 3y = 24                      ................(ii)

From equation (ii),

x = 24 + 3y                .............(iii)

Substitute this value of x in equation (i)

⇒ 4(24 + 3y) +2y = -2

⇒ 96 + 12y + 2y = -2

⇒ 14y = -98

⇒ y = -7

Substitute this value of y in equation (iii)

⇒ x = 24 + 3(-7)

⇒ x = 24 - 21

⇒ x = 3

Therefore, the solutions of the above system of equations is x = 3 and y = -7 and the graph of above system of equations is as shown below.

The Revenue generated by theater is  $2,250.

Simply put, to simplify is to make something simpler. Simplifying an equation, fraction, or issue in mathematics entails taking something complex and making it simpler. The issue is made simpler by calculations and problem-solving strategies. We can simplify fractions by removing all common elements from the numerator and denominator and putting the fraction in its simplest/lowest form.

It is possible to simplify mathematical formulas by merging and grouping related terms. This makes it easy to understand and decipher the puzzle.

Given total ticket sold = 390

adult ticket + child  ticket = 390

and  2.25 times as many adult tickets as child tickets

so adult ticket  = 2.25 child tickets

Let child ticket be x

adult ticket = 2.25x

equation will be

2.25x + x = 390

3.25x = 390

x = 120

adult ticket = 390 - 120 = 270

cost of 1 adult ticket = $7

cost of 270 adult ticket = 7 x 270 = $1890

cost of 1 child ticket = $3

cost of 120 child ticket = 3 x 120 = $360

Total revenue = $1890 + $360

Total revenue = $2,250

Hence the total collection of theater is $2,250.
