1,000,000 minutes is about 2 (1.9) years.

The average person lives for 78 years, or 41,000,000 minutes

First the top right quart

area = 16, 4 * 4

Then the top left quart

making a 2 by 4 triangle followed with 4 additional square

making 2 * 4 * 1/2 = 4 + 4 meaning area = 8

then the bottom quart

Making a large triangle of 7 by 3

meaning 7 * 3 * 1/2 = 10.5

total area = 16 + 8 + 10.5 = 34.5

Answer:

x = 20 degrees

y = 128 degrees

Step-by-step explanation:

First, lets solve for x:

3x-8 = 2x + 12

x = 20 degrees

Let's check our work:

60 - 8 = 40 + 12

52 = 52

Now, lets solve for y:

360 - 104 = 256

Why 360? Because 360 degrees = full circle

256/2 = 128 degrees

y = 128 degrees

Why divided by 2? Because there are 2 parts that are equal (y)

Answer:

The volume and surface area of this square pyramid is approximately 277.33 [tex]m^3[/tex] and 281.6 [tex]m^2[/tex] respectfully.

Step-by-step explanation:

To find the volume of a pyramid, you need to multiply the base area by the vertical height and divide it by 3. In this case, the volume of the square pyramid would be [tex]\frac{8*8*13}{3}[/tex] = [tex]\frac{64*13}{3}[/tex] = [tex]\frac{832}{3}[/tex] ≈ 277.33 [tex]m^3[/tex]. If you want to find the surface area of a shape, you have to calculate the area of every side making up the 3-dimensional figure and add them all together to figure out the surface area. In this case, the surface area would be [tex]\frac{13.6*8}{2} *4 + 8^2[/tex] = [tex]\frac{108.8}{2} * 4 + 64[/tex] = [tex]54.4 * 4 + 64[/tex] = [tex]217.6+64[/tex] = 281.6 [tex]m^2[/tex]. So the volume of the square pyramid would be approximately 277.33 [tex]m^3[/tex], and the surface area is 281.6 [tex]m^2[/tex].

Answer:

0.75 cups

Answer:

VF= $25.088.000

Step-by-step explanation:

Dada la siguiente información:

Inversión inicial (VP)= $20.000.000

Tasa de interes (i)= 12% anual

Número de periodos (n)= 2 años

Para calcular el falor futuro (VF) de la inversión, debemos usar la siguiente formula:

VF= VP*(1 + i)^n

VF= 20.000.000*(1,12^2)

VF= $25.088.000

Hope this helps!

Step-by-step explanation:

The exact question is as follows :

Given - The value of π up to 35 decimal places is given below:

3.14159265358979323846264338327950288

To find - Make a frequency distribution of the digits 0 to 9 after the decimal point.

Proof -

The Frequency Distribution Table for digits after decimal point in the value of Pi is :

Digits        Frequency after decimal point

0                               1

1                               2

2                               5

Answer:

113°

Step-by-step explanation:

triangles add up to 180°

180° - 34° - 33° = 113°

==============================================

Explanation:

For any triangle, the three interior angles must add to 180 degrees

34+33+x = 180

x+67 = 180

x = 180-67 ... subtract 67 from both sides

x = 113

This triangle is obtuse because the 113 degree angle is larger than 90 degrees. Also, the triangle is scalene because all three angles are different values (consequently, it means all three sides are different from one another).

Answer:

Step-by-step explanation:

Step 1: Convert the discounted percent to decimal

20% = 0.2

Step 2: Multiply the discount to the item regularly priced

0.2(65.00) = 13

So, Bill received a $13 discount, therefore, the amount he paid AFTER his discount is:

Step 3: Subtract the result (the discount Bill received) from the regular price

$65.00 - $13.00= $52.00

Therefore, Bill paid $52.00

Step 1: Multiply the wholesale price for a pillow by the marked-up the wholesale price

$4.50 × 40% = 1.8

[tex]\frac{4.50}{x}=\frac{100\%}{40\%}[/tex]

[tex]\frac{x}{4.50}=\frac{40}{100}[/tex]

x = 1.8

Step 2: Add the result to the wholesale price for the pillow

4.50 + 1.8 = $6.3

Step 3: Round to the nearest cent

Add a zero behind the result = 6.30

Therefore, the price of the pillow in the department store is $6.30

Answer:

B (-4,-4)

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Since it is currently at (4,2), reflecting it across y=-1 will bring the y-coordinate down to -4. After that, reflecting it across the y-axis will flip the sign in front of the x-coordinate, so 4 to -4. Therefore, your answer is (-4,-4).

Answer:

False, A polygon must have at least 3 sides.

Step-by-step explanation:

A polygon must have at least 3 sides. Not at least 2 sides.

A polygon must have at least three sides so the statement that a polygon must have at least two sides is false.

We have,

A polygon is a closed figure formed by straight lines called sides.

By definition,

A polygon must have at least three sides.

A polygon with only two sides would be classified as a line segment, not a polygon.

Thus,

A polygon must have at least two sides is false.
