Answer:

A: Day 6

B: 8196 grams (He will become obese for sure)

Step-by-step explanation:

Part A:

As you can infer from the problem, Ali halves his bar everyday, regardless of how the bar is.

Day 1= 32 grams left

Day 2= 16 grams left

Day 3= 8 grams left

Dat 4= 4 grams left

Day 5= 2 grams left

Day 6=1 gram left

He will have one gram left on Day 6

Part B:

This part is basically vice versa. Instead on halving, we need to be doubling. I will do Part a in reverse until Day 14 comes

Day 1= 1

Day 2= 2

Day 3= 4

Day 4= 8

Day 5= 16

Day 6= 32

Day 7 = 64

Day 8= 128

Day 9= 256

Day 10= 512

Day 11= 1024

Day 12= 2048

Day 13= 4096

Day 14= 8192

He will need 8192 grams of chocolate!!!

The number of days when he has only 1 gram left will be 6. And the chocolate needs to weigh to last All 14 days will be 1/256 grams.

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as

y = a(b)ˣ

Ali has a 64 grams bar of chocolate.

On day 1 he eats half of his chocolate.

And on day 2 he eats half of what is left.

He does the same each day.

Then the value of a is 64 grams and b is 1/2.

y = 64 · (1/2)ⁿ

Where n is the number of days.

The number of days when he has only 1 gram left will be

1 = 64 · (1/2)ⁿ

1/64 = (1/2)ⁿ

(1/2)⁶ = (1/2)ⁿ

n = 6

The number of days when he has only 1 gram left will be 6.

The chocolate needs to weigh to last All 14 days will be

y = 64 · (1/2)¹⁴

y = 64 · (1/16384)

y = 1/256 grams

The chocolate needs to weigh to last All 14 days will be 1/256 grams.

Answer: C. 30 degrees

Step-by-step explanation:

By definition, an hexagon is a polygon with six sides.

The sum of the interior angles of an hexagon is 720 degrees.

Based on this, the measure of eac interior angle is:

A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a constant. This is different from a quadratic function which does not represent a geometric sequence.

In mathematics, a function represents a geometric sequence when each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio. The general form of a geometric sequence can be written as a, ar, ar^2, ar^3, ... where 'a' is the first term, and 'r' is the common ratio.

The important factor in a geometric sequence is the multiplication by a constant. For example, let's say we have a sequence 2, 4, 8, 16. This is a geometric sequence because each term is multiplied by 2 to get the next term.

In contrast, a quadratic function, for instance, does not represent a geometric sequence as it's formed by the equation ax^2 + bx + c where a, b, and c are constants.

Answer:

The angular velocity of Earth is π/12 radians per hour.

The angular velocity of Earth is 2π radians per day.

Step-by-step explanation:

A full circumference of a circle (as the Equator line on Earth) is 2π radians.

Since the planet does a full revolution in 24 hours... that means it makes a full turn in a day.

So, we can see that in a day, the planet rotates 360 degrees... or 2π radians per day!

Now, if you want to find the angular velocity per HOUR... you divide that by 24... so  2π/24 = π/12 radians

So, we can also say it does π/12 radians per hour.

Answer:

Step-by-step explanation:

The easiest to solve for is y in the second equation.   Just subtract 3x from both sides, obtaining y = -3x + 9.

The value of x = 1 and y = 6. The easiest to solve for is y in the second equation.

Let the equations be

2x + 4y = 26 ......(1)

3x + y = 9 ........(2)

From (2), we get

3x + y = 9

y = -3x + 9 .......(3)

then substitute the value of y in (1), then we get

2x + 4y = 26

2x + 4(-3x + 9) = 26

Simplifying the above equation, we get

2x - 12x + 36 = 26

-10x + 36 = 26

-10x = 26 - 36

-10x = -10

Then the value of x = 1

Substitute the value of x in (3), then we get

y = -3x + 9

Simplifying the equation, we get

y = -3(1) + 9

y = -3 + 9

y = 6

The value of x = 1 and y = 6.

The conversion from 2000 Swiss francs to Dutch guilders requires a historical exchange rate which is not provided. The Dutch guilder is obsolete since 2002, and precise conversions cannot be made without the rate from the time period when both currencies were in use.

To convert 2000 Swiss francs to Dutch guilders, you would need to know the specific exchange rate between the Swiss franc and the Dutch guilder at the time of the conversion. Unfortunately, as of today, the Dutch guilder is no longer in use, as the Netherlands adopted the euro as its currency in 2002. However, if you were to convert currencies similar to how holders of dollars are willing to exchange $2,500 for euros or vice versa, you would need the specific exchange rate from Swiss francs (CHF) to Dutch guilders (NLG) during the time when both currencies were in use.

Without historical exchange rate data, it is impossible to provide an exact number of Dutch guilders you would receive for 2000 Swiss francs. If you have a specific date in mind, you could find the historical exchange rate for that date and then calculate the conversion using this formula:

Amount in Swiss francs * Exchange rate (CHF to NLG) = Amount in Dutch guilders

Remember, when performing historical currency conversions, it's essential to use the correct exchange rate from the time period in question.

Answer: Infinitely Many Solutions

For a system of linear equations, there are three types of solutions. They are,

Infinitely many solutions are there for a system if they both are equal on both sides while solving. (their graphs intersect at all the points)

Given the system of equations as

y = -2x - 6

2y = -4x - 12

Using substitution method, substituting first equation into the second equation,

2( -2x -6) = -4x - 12

⇒ -4x -12 = -4x - 12

Thus, both sides are equal, and the given system has infinitely many solutions.

Answer:

Marcus practiced for 4 hours and Donnell practiced for 7 hours

Step-by-step explanation:

We can set up this problem as a system of linear functions

We'll use d to represent Donnell and m to represent Marcus

Since Donnell practiced 3 hours more than Marcus, we can represent this as an equation:

d=m+3

And since they both practiced for a combined total of 11 hours, we can represent this an an equation:

d+m=11

We can substitute d=m+3 into d+m=11 and we get:

m+3+m=11

2m+3=11

2m=8

m=4

Now we can substitute m=4 into d+m=11

d+4=11

d=7

Therefore, Donnell practiced for 7 hours and Marcus practiced for 4 hours

For simplicity, let's assume that l = w = h, then [tex]V = \dfrac{1}{3}s^3[/tex]

Pyramid 1 has a volume of 64:

[tex]64=\dfrac{1}{3}s^3\\\\3\times 64=s^3\\\\\sqrt[3]{3\times 64}=\sqrt[3]{s^3}  \\\\4\sqrt[3]{3} =s[/tex]

Pyramid 2 has a volume of 8:

[tex]8=\dfrac{1}{3}s^3\\\\3\times 8=s^3\\\\\sqrt[3]{3\times 8}=\sqrt[3]{s^3}  \\\\2\sqrt[3]{3} =s[/tex]

Comparing the sides of Pyramid 1 to the sides of Pyramid 2:

[tex]\dfrac{4\sqrt[3]{3}}{2\sqrt[3]{3}}=\dfrac{2}{1}\implies \text{scale factor of }2:1[/tex]

The scale factor of two similar pyramids with volumes of 64 cubic feet and 8 cubic feet is 2.

Understanding the Scale Factor of Similar Pyramids

To find the scale factor between two similar pyramids, we need to understand the relationship between their volumes and their corresponding dimensions. The volumes of the two pyramids given are 64 cubic feet and 8 cubic feet.

The formula for the volume of similar shapes indicates that the volume varies as the cube of the scale factor. This can be mathematically expressed as:

If V1 and V2 are the volumes of two similar figures with a scale factor of k, then: V1 / V2 = k3

For this problem:

64 ÷ 8 = k3

Simplifying:

8 = k3

Taking the cube root of both sides:

k = 2

So, the scale factor of the two similar pyramids is 2.

y = - 5x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

here m = - 5 and b = - 7, hence

y = - 5x - 7 ← equation of line

Since b equals the y-intercept, we automatically know that the answer will be in slope-intercept form which is y = mx + b where m equals slope and b equals the y-intercept.

Given.

m = –5, b = –7

Slope intercept formula.

y = mx + b

Plug in m = -5 and b = -7.

y = -5x - 7 ← Choice C

Since the numbers are not consecutive natural numbers, how about if I let the 4 numbers be a, b, c, and d?

The sum is given to be 1320.

a + b + c + d =1320...I will call this the first equation.

Can I then say that the second equation is b + c + d = 0.4a + a? Yes, I can do this.

Simplifying my second equation,

I get b + c + d = 1.4a.

Plugging this into my first equation, I get

a +1.4a =1320

2.4a =1320

So, a =1320/(2.4) =550.

Answer: 550

Answer:

550

Step-by-step explanation:

We aren't given that they are consecutive so lets just pretend the numbers are x, y, z , and r.

We are given x+y+z+r=1320

We are also given that y+z+r=.4x+x

Simplifying my second equation gives us y+z+r=1.4x. I'm going to plug this into first equation giving me

x+1.4x=1320

2.4x=1320

So x=1320/2.4=550
