Mandvil has one standard quarter and one special quarter with a Head on both sides. He selects one of these two coins at random, and without looking at it first, he flips the coin three times. If he flips a Head three straight times, what is the probability that he selected the special quarter?

Answer:

97 1/5 cubed ft. or 97.2 cubed ft.

Step-by-step explanation:

7 1/5=7.2

4 1/5=4.5

3=3

7.2x4.5x3=97.2=97 1/2

Answer:

[tex]V = 97.2\ ft^3[/tex]

Step-by-step explanation:

Step 1:  Determine the volume

[tex]V = l * w * h[/tex]

[tex]V = 4.5\ ft * 3\ ft * 7.2\ ft[/tex]

[tex]V = 97.2\ ft^3[/tex]

Answer:  [tex]V = 97.2\ ft^3[/tex]

Answer:

Step-by-step explanation:

Each box is 1 larger than the earlier one, so the boxes are 1, 2, 3, 4, and 5.

4 + 5 is the width across the bottom

2 + 3 is the width across the top (not counting h)

9 - 5 = 4, so h = 4

The value of h is 4. Hence, Option C is the best choice.

Found using the area of the given square.

The area of a square is the square of its sides.

If a represents the side of the square, then its area is a².

In the question, we are given five squares positioned as shown in the figure. The smallest square has an area of 1.

We are asked to find the value of h.

Now, the square of area 1, will have sides of length √1 = 1.

The second square, just greater than this, is nearly 1.5 times this square.

Hence the side of that square = 1.5*1 = 1.

The third square has a side equal to the sum of the side of these two squares. Hence, its side = 1 + 1.5 = 2.5.

The fourth square has a side equal to the sum of the third and the first square. Hence, its side = 2.5 + 1 = 3.5.

The fifth square has a side equal to the sum of the fourth and the first square. Hence, its side = 3.5 + 1 = 4.5.

Now, h = length of the fifth square - (length of the second square - length of the first square),

or, h = 4.5 - (1.5 - 1) = 4.5 - 0.5 = 4.

Hence, the value of h is 4. Hence, Option C is the best choice.

Answer:

21 - 3 + 18 ÷ 6 = 21

7 x 9 - 3 x 4 + 10 = 61

Step-by-step explanation:

Answer:

7.07 cm

Step-by-step explanation:

we know,

circumference = 2πr

so,

2 × 22/7 × r = 66

44r = 66×7 = 462

r = 462/44 = 1.5

therefore, radius of the circle is 1.5 cm.

now,

we know , area = πr²

so,

22/7 × (1.5)²

22/7 × 2.25

49.5/7

7.07 cm (approx)

therefore, area of the circle is 7.07 cm (approx.)

False, The range for an exponential function does not include all real numbers but only real numbers greater than zero.

In mathematics, an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.

Given statement,

The range for an exponential function includes all real numbers.

By the definition,

Exponential functions have the general form y = f (x) = aˣ,

where a > 0, a≠1, and x is any real number.

The reason a > 0 is that if it is negative, the function is undefined for -1 < x < 1. Restricting a to positive values allows the function to have a domain of all real numbers.

Thus the range is all real numbers greater than zero.

Hence, The range for an exponential function includes all real numbers is False because it includes real numbers greater than zero.

Let the number be x

Now we have a equation,

X÷2=260

x=260×2

x=520

Hence, the number you started with was 520.

Answer:

x=1 or x=16

Step-by-step explanation:

3/4x = 12      or        0.75x = 12

3/4x/3/4 = 12/3/4     or     0.75x/0.75 = 12/0.75

x=12/1 / 3/4

x= 4/4

x = 1                           or       x = 16

Answer:

Elena made 10 batches.

Step-by-step explanation:

1 batch uses 2/3 cup

Elena used 6 2/3 cup

The number of batches is the quotient of 6 2/3 and 2/3.

We need to divide 6 2/3 by 2/3. First, we convert 6 2/3 into a fraction.

6 2/3 ÷ 2/3 = 20/3 ÷ 2/3 = 20/3 × 3/2 = 10

Answer: Elena made 10 batches.

Answer:

10

Step-by-step explanation:

2/3 for 1 cup if he used 6 2/3 of sugar then its 10.

if you times 2/3 by 10 its 6.66 and 6.66 is 2/3

Answer:

D. x = 8

Explanation:

Triangle ACD is an enlarged triangle of Triangle ABE

so an equation can be formed to solve this:

[tex]\frac{3x}{30}[/tex] = [tex]\frac{48}{30+30}[/tex]

[tex]\frac{3x}{30}[/tex] = [tex]\frac{48}{60}[/tex]

3x * 60 = 48 * 30

180x = 1440

x = 1440 ÷ 180

x = 8

Triangle ACD is an enlarged triangle of Triangle ABE

so an equation can be formed to solve this:

[tex]\frac{3x}{30} = \frac{48}{30 + 30} [/tex]

[tex] \frac{3x}{30} = \frac{48}{60} [/tex]

[tex] \frac{3x}{60} = \frac{48}{30} [/tex]

[tex]180x = 1440[/tex]

[tex]x = \frac{1440}{180} [/tex]
