In a survey of students , every student studies at least one of the three subjects Maths English and Science . The number of students who study only one subject is twice the number of students who study only two students . If 20 students study all three and 80 students who study only two subjects, find the total number of students in the survey. ​

Answer:

1,100

Step-by-step explanation:

The total area of the football stadium's spectator area is 3000 square feet.

The area of a rectangle is defined as the product of the length and width.

The area of a rectangle = L × W

Where W is the width of the rectangle and L is the length of the rectangle

The total area of the football stadium's spectator area is the product of the length and width of the seating area.

Since the length of the seating area is 50 feet and the width is 60 feet, the total area is:

total area of the football stadium = 50 feet × 60 feet

Apply the multiplication operation, and we get

total area of the football stadium = 3000 square feet

Therefore, the spectator space of the football stadium is 3000 square feet in total.

Answer:

(3,2)

Step-by-step explanation:

Missing Information:

The coordinate of the grocery store is: (2,5).

Required:

Determine the starting point

Assume the starting coordinate is (x, y)

When a point (x, y) is translated b units left, the image of the translation is: x -> x - b

In this case:

b = 1 (i.e. 1 unit left)

So, we have:

[tex](x-1,y)[/tex]

When a point (x, y) is translated h units up, the image of the translation is: y -> y + h

In this case:

h = 3 (i.e. 3 units up)

So, we have:

[tex](x-5,y+3)[/tex]

So, the expression that describes the grocery store is:

[tex](x-1,y+3) = (2,5)[/tex]

By comparison:

[tex]x-1 = 2[/tex]

[tex]y+3=5[/tex]

Solve for x

[tex]x = 2 + 1[/tex]

[tex]x = 3[/tex]

Solve for y

[tex]y = 5 - 3[/tex]

[tex]y = 2[/tex]

Hence, the starting point is: (3,2)

Answer:

21,872 tickets

Step-by-step explanation:

The computation of the number of tickets to be still sold is given below:

= Total people accommodated - total number of tickets sold yet

= 50,000 people - (13,520 tickets + 14,608 tickets)

= 50,000 people - 28,128 tickets

= 21,872 tickets

Answer:

96 minutes

Step-by-step explanation:

Time taken by 6 pipes to fill a tank = 80 minutes

The closest point to the number line is C.

Hence Option C is correct.

In the given number line

There are 10 equidistant points between 3.1 and 3.2

So, the set of points shown on the line is,

{3.1, 3.11, 3.12, 3.13, 3.14, 3.15, 3.16, 3.17, 3.18, 3.19, 3.2}

Therefore,

Point c represents point 3.14 approximately.

Since we know that π is an irrational number,

So it is non-terminating and non-repeating but for approximation,

π = 22/7

π ≈ 3.142

Hence,

The point C is very close to the π.

Answer:

D

Step-by-step explanation:

Quadratic formula tells us that the roots are equal to:

[tex]\frac{-b\pm \:\sqrt{b^2-4ac}}{2a}[/tex]

The letters are just the coefficients, so a = 4, b = -11, and c = -18. Plugging these values into the formula we get:

[tex]\frac{-11\pm \sqrt{11^2-4\cdot \:4\left(-18\right)}}{2\cdot \:4}[/tex]

Which when simplified tells us that the roots are:

[tex]\frac{-11+\sqrt{409}}{8}[/tex] or [tex]\frac{-11-\sqrt{409}}{8}[/tex]

Remember the plus or minus sign is what gives us two answers.

Answer:

57 is your answer......

Answer:

51,200 unidades

Step-by-step explanation:

Paso 1

Calculamos el porcentaje de disminución

= 100000 - 80000/100000 × 100

= 20000/100000 × 100

= 20%

Por lo tanto, el porcentaje de disminución cada mes = 20%

Paso 2

La fórmula de la disminución exponencial

y = a (1 - r) ^ t

a = 80.000

r = 20% = 0,2

t = tiempo en meses = 2

y = 80000 (1 - 0,2) ^ 2

y = 51.200 unidades

Usando una función exponencial, se encuentra que habra 71.554 unidades despues de los siguientes dos meses.

Una función exponencial decreciente tiene el siguiente formato:

[tex]A(t) = A(0)(1 - r)^t[/tex]

En que:

En este problema:

[tex]A(t) = A(0)(1 - r)^t[/tex]

[tex]80000 = 100000(1 - r)^4[/tex]

[tex](1 - r)^4 = 0.8[/tex]

[tex]\sqrt[4]{(1 - r)^4} = \sqrt[4]{0.8}[/tex]

[tex]1 - r = 0.945742[/tex]

Por eso:

[tex]A(t) = A(0)(1 - r)^t[/tex]

[tex]A(t) = 100000(0.945742)^t[/tex]

Apos el siguinte dos meses, hay el mes 6, por eso:

[tex]A(6) = 100000(0.945742)^6 = 71554[/tex]

Habra 71.554 unidades despues de los siguientes dos meses.

Answer:

Step-by-step explanation:

Step 1:

Start by setting it up with the divisor 4 on the left side and the dividend 34 on the right side like this:

   4 ⟌ 3 4  

Step 2:

The divisor (4) goes into the first digit of the dividend (3), 0 time(s). Therefore, put 0 on top:

       0    

   4 ⟌ 3 4  

Step 3:

Multiply the divisor by the result in the previous step (4 x 0 = 0) and write that answer below the dividend.

       0    

   4 ⟌ 3 4  

       0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (3 - 0 = 3) and write the answer below.

       0    

   4 ⟌ 3 4  

     - 0    

       3    

Step 5:

Move down the 2nd digit of the dividend (4) like this:

       0    

   4 ⟌ 3 4  

     - 0    

       3 4  

Step 6:

The divisor (4) goes into the bottom number (34), 8 time(s). Therefore, put 8 on top:

       0 8  

   4 ⟌ 3 4  

     - 0    

       3 4  

Step 7:

Multiply the divisor by the result in the previous step (4 x 8 = 32) and write that answer at the bottom:

       0 8  

   4 ⟌ 3 4  

     - 0    

       3 4  

      3 2  

Step 8:

Subtract the result in the previous step from the number written above it. (34 - 32 = 2) and write the answer at the bottom.

       0 8  

   4 ⟌ 3 4  

     - 0    

       3 4  

     - 3 2  

         2  

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 34 divided by 4 calculated using Long Division is:

8

2 Remainder

Answer:

4 remainders

Step-by-step explanation:

Here we will show you step-by-step with detailed explanation how to calculate 4 divided by 34 using long division.

Before you continue, note that in the problem 4 divided by 34, the numbers are defined as follows:

4 = dividend

34 = divisor

Step 1:

Start by setting it up with the divisor 34 on the left side and the dividend 4 on the right side like this:

 3 4 ⟌ 4    

Step 2:

The divisor (34) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:

       0    

 3 4 ⟌ 4    

Step 3:

Multiply the divisor by the result in the previous step (34 x 0 = 0) and write that answer below the dividend.

       0    

 3 4 ⟌ 4    

       0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.

       0    

 3 4 ⟌ 4    

     - 0    

       4    

You are done.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 4 divided by 34 calculated using Long Division is:

0
