Answer:

98 calories is the closest estimate

590 x 2 = 1180

1180 / 12 = 98.3

Answer:

the answer is 256

Step-by-step explanation:

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:

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.

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:

1225 cm²

Step-by-step explanation:

Keliling persegi diberikan sebagai 4 × a

Dimana a = Panjang sisi

Keliling persegi di atas = 140

Karenanya:

4a = 140

a = 140/4

a = 35 cm

Panjang sisi bujur sangkar = 35cm

Luas persegi = (Panjang sisi) ²

Karenanya:

Luas persegi = (35cm) ²

= 1225 cm²

Luas persegi sebelum membagi adalah 1225 cm²

Answer:

H = 35

Step-by-step explanation

21 / 3 is 7 so multiply 7 by 5 to get 35. So 35 is equal to H.

Both answer is 65

Step-by-step explanation:

5x -30 = 2x +27

5x -2x = 27 +30

3x = 57

x = 57/3 = 19

5x -30 = 5(19) -30 = 65

2x +27 = 2(19) +27 = 65

Answer:

B. 20

Step-by-step explanation:

Using the Pythagorean Theorem, you have:

[tex]a^2 + b^2 = c^2\\24^2 + 32^2 = c^2\\576 + 1024 = c^2\\1600 = c^2\\c = 40[/tex]

So you know side AB is 40 inches long. It asks the length of the midpoint to point A, so you have to do 40/2 = 20 inches

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:

(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)

Step-by-step explanation:

step 1. an example of difference of squares (dos) is (x + y)(x - y) = x^2 - y^2.

step 2. dos must have only 2 square rootable terms and a "-" between them.

step 3. 196x^2 - 121y^2 = (14x + 11y)(14x - 11y) works!

step 4. 5x^2 - 245 = 5(x^2 - 49) = 5(x + 7)(x - 7) works!

step 5. 27w^5 - 75w = 3w(9w^4 - 25) = 3w(3w^2 + 5)(3w^2 - 5) works!

step 6. x^4 - 100y^2 = (x^2 - 10y)(x^2 + 10y) works!

Answer:

123.6

Step-by-step explanation:

Find the area of the circle, because the four quarter circles add to one circle. The circle has a diameter of 24, so the area of it is 452.4. The square has an area of 24*24, so the area is 576. Subtract the area of the circle from the square, and you get 123.6. Hope this helps!

Answer:

the width is 360 ft

Step-by-step explanation:

The computation of the width of the flag is shown below:

Let us assume the width be x

So the length would be x + 340

And, the perimeter is 2,120 ft

So the formula is

Perimeter = 2(length + width)

2,120 = 2(x + 340 + x)

2,120 = 2x + 680 +  2x

2,120 = 4x + 680

4x = 2,120 - 680

x = 360

hence, the width is 360 ft
