Answer:

The number of buyers on the first day was approximately 324.

Step-by-step explanation:

In this case we have a initial number of shoppers "C" that we want to know and this grows at a steady rate of 20% per day, like a compound interest, we also know the total number of shoppers after 4 days, so we have the final amount of shoppers. We can use the formula for compound interest in order to calculate the number of shoppers in the first day as shown bellow:

M = C*(1 +i)^(t)

Where M is the total amount of shoppers, i is the growth rate and t is the time elapsed.

671 = C*(1 + 0.2)^(4)

671 = C*(1.2)^4

671 = C*2.0736

C = 671/2.0736 = 323.5918

Since there can't be a 0.59 buyer, we will round the number to 324.

Step-by-step explanation:

Instead, you will use diagrams. To solve such a problem, you must produce a diagram which clearly shows all of the fractions involved in the ... between them have eaten five of the pieces, they have eaten 5/6 of the cake. We also see that ... counting numbers with M<N), then you must show the thing, show it clearly.

To solve the equation 2x(x+3)-5(x+3)=0, distribute the terms within the parentheses and combine like terms. Then, use the quadratic formula to find the solutions of the quadratic equation.

To solve the equation 2x(x+3)-5(x+3)=0, let's distribute the 2x and -5 into the terms inside the parentheses: 2x^2 + 6x - 5x - 15 = 0. Combining like terms, we get 2x^2 + x - 15 = 0. Now we can use the quadratic formula, which states that for an equation of the form ax^2 + bx + c = 0, the solutions are given by:

x = (-b ± √(b^2 - 4ac)) / (2a)

In our case, a = 2, b = 1, and c = -15. Plugging these values into the quadratic formula, we get:

x = (-1 ± √(1^2 - 4(2)(-15))) / (2(2))

x = (-1 ± √(1 + 120)) / 4

x = (-1 ± √121) / 4

x = (-1 ± 11) / 4

So the two solutions are x = 10/4 and x = -12/4, which can be simplified to x = 5/2 and x = -3.

Answer: B) 10cm Just count the squares but 2 halves = 1 full

8.54

Simplest way to do it is using the Pythagorean Theorem

c^2 = a^2 + b^2

You want c. We can get a and b from the chart by seeing that the horizontal distance from A to B is 8 and the vertical distance is 3. Otherwise,

a = |-4| + 4 = 8, horizontal distance

b = |-5| + |-2| = 3, vertical distance

Then,

[tex]c = \sqrt{ {8}^{2} + {3}^{2} } = \sqrt{73} = 8.54[/tex]

Missing part of the question

Miguel has started training for a race. The first time he trains, he runs 0.5 mile. Each subsequent time he trains, he runs 0.2 mile farther than he did the previous time.

What is the arithmetic series that represents the total distance Miguel has run after he has trained n times?

Answer:

The least number of times Miguel must run for his total distance run during training to exceed the distance of a marathon is 17.3 miles

Step-by-step explanation:.

Given parameters

Miguel first run = 0.5 mile

Subsequent run = 0.2 mile

This question is an arithmetic progression.

We'll make use of arithmetic progression formula to solve this

Formula:.

Tn = a + (n - 1)d

Where a = first term

n = number of terms

d = common difference

In this case

a = first run = 0.5 mile

d = subsequent run = 0.2 mile

So, Tn = a + (n - 1)d become

Tn = 0.5 + (n - 1) 0.2

Tn = 0.5 + 0.2n - 0.2

Tn = 0.5 - 0.2 + 0.2n

Tn = 0.3 + 0.2n

The arithmetic series of an arithmetic progression is calculated using

Sn = ½(a + Tn) * n

By substituton, we have

Sn = ½(0.5 + 0.3 + 0.2n) * n

Sn = ½(0.8 + 0.2n) * n

Sn = 0.4n + 0.1n²

b.

Since the race is 26.2 miles then the least number of times is given as

Sn ≥ 26

0.4n + 0.1n² ≥ 26.2

0.1n² + 0.4n - 26.2 ≥ 0

Using quadratic formula

n = (-b ± √(b² - 4ac))/2a

Where b = 0.4 a = 0.1 and C = -26.2

So,

n = -0.4 ± √(0.4² - 4 * 0.1 * ,26.2)/2 * 0.1

n = (-0.4 ± √10.64)/0.2

n = (0.4 ± 3.26)/0.2

n = (0.4 + 3.26)/0.2 or (0.4 - 3.26)/0.2

n = 3.46/0.2 or -2.86/0.2

n = 17.3 or -14.3

Since n can't be negative

n = 17.3 miles

The least number of times Miguel must run for his total distance run during training to exceed the distance of a marathon is 17.3 miles

What is the radius of the cone?

5ft

What is the area of the base of the cone?

25ft

What is the volume of the cone?

75ft

Step-by-step explanation:

1) Radius of the cone = 5ft

2) Area of the base of the cone =  78.5 square feet

3) Volume of the cone = 235.5 cubic feet

A cone is a distinctive three-dimensional geometric figure that has a flat surface and a curved surface, pointed towards the top. The pointed end of the cone is called the vertex, whereas the flat surface is called the base.

According to the given problem,

Diameter of the cone = 10 feet

Radius of the cone = [tex]\frac{diameter}{2}[/tex]

                                = 5 feet

Area of the base of the cone = [tex]\pi[/tex]r²

                                                 = [tex]\pi[/tex] × (5)²

                                                 = 78.5 square feet

Volume of the cube = [tex]\pi[/tex]r²[tex](\frac{height}{3})[/tex]

                                  = 235.5 cubic feet

Hence, we can conclude that the cone shown in figure has a radius of 5 feet , base area of 78.5 feet and a volume of 235.5 cubic feet.

Given the expression in decimal form, we can convert this to factional form and perform product operations as an alternative computational method

6.15*(-3.11)= 19.13

In fraction 6.15 can be written as

615/100

In fraction -3.11 can be written as

-311/100

Hence The product can also be expressed as fractions

615/100*(-311/100)

Answer:

(6 x (-3.11)) + (0.15 x (-3.11))

Step-by-step explanation:

In the given expression, the term 6.15 can be written as follows.

6.15 = 6 + 0.15

Apply the distributive property.

6.15 x (3.11) = (6 x (-3.11)) + (0.15 x (-3.11))

x = 14

Step-by-step explanation:

12(3x - 2) = 32(x + 1) ← distribute both sides

36x - 24 = 32x + 32 ( subtract 32x from both sides )

4x - 24 = 32 ( add 24 to both sides )

4x = 56 ( divide both sides by 4 )

x = 14

The value of x given that JKL ~ MKN is; x= 14.

According to the question;

Based on ratios; We can conclude that;

[tex] \frac{12}{x + 1} = \frac{32}{3x - 2} [/tex]

Answer: C. 0.19     Hope this helps!    

Answer:

You don't have a question but I'll answer what I can.

half-life = natural log (.5) / k

half-life =  -.693147 / .1247

half-life = 5.561106656

It seems you did not express the k-value properly.

1) A k-value should have a negative value.

2) A k-value should also have units.

For example, the k-value of tungsten 181 is

-0.005723757 / days

Step-by-step explanation:

Final answer:

a half-life of 5.5 days.

Explanation:

To find the half-life (t1/2) using the decay constant (k), the formula that relates them for the decay of a radioactive substance, typically used for first-order kinetics, is t1/2 = ln(2)/k, where ln(2) is the natural logarithm of 2. Given the decay constant k = 0.125, the half-life is calculated as follows:

t1/2 = ln(2) / 0.125

t1/2 = 5.545 / 0.125

t1/2 = 5.5 days

The mass of the substance does not affect the half-life, so the initial 11-gram sample size is not used in the calculation. Thus, the substance's half-life, rounded to the nearest tenth, is 5.5 days.

EASY! First we have to find the area of the back yard.

Step-by-step explanation:

[tex]A=12*10\\A=120[/tex]

So, we have to convert feet to yards(as it's in feet and we are doing our calculations in yards).

(And also, due to the fact it's squared, we have to square our coefficient as well).

The formula states we have to divide by 3, thus:

[tex]\frac{400}{3^{2} } =\frac{400}{9 }=44.444...[/tex]

Hmmm. Might be better if we do it the other way around. Might be simpler.

Thus:

[tex]120*9=1,080[/tex]

So then we divide 1,080 by 400, as the bag covers 400 feet

[tex]\frac{1080}{400} =2.7[/tex]

So, he needs 3 bags(as he cannot use two to cover the entire back yard). He will have a little left over, but that's okay, because he cannot buy 0.7 of a bag.

Then we multiply this by the cost!

[tex]3*25.99=77.97[/tex]

So, Kenneth would have to pay $77.97 and have a little left over!

Hope I did this right!
