Answer:

516

Step-by-step explanation:

First

34% small and 40% large means that 100 - (34 + 40) = 26% medium

26% of 600 = 0.26 × 600 = 156

----------------------------------------------------

Second

[tex]\frac{3}{10}[/tex] are small and [tex]\frac{1}{10}[/tex] are large, which means [tex]\frac{6}{10}[/tex] are medium

[tex]\frac{6}{10}[/tex] × 400 = 0.6 × 400 = 240

-----------------------------------------------------

Third

sum the parts of the ratio, 3 + 4 = 7

Divide 210 by 7 to find the value of one part of the ratio

210 ÷ 7 = 30 ← value of 1 part of ratio

Thus medium = 4 × 30 = 120

Total number of medium packets = 156 + 240 + 120 = 516

Answer:2.8 x 10^-6. hope this helps :)

Final answer:

The expression (7 x 10⁻¹²)(4 x 10⁵) in scientific notation is 2.8 x 10⁻⁷.

Explanation:

The expression in scientific notation for the product (7 x 10⁻¹²)(4 x 10⁵) is found by multiplying the coefficients (7 and 4) and then adding the exponents of 10 (as they have the same base). Multiplying the coefficients gives us 28, and adding the exponents of 10 (-12 + 5) gives us -7 as the new exponent.

The final result in scientific notation is 2.8 x 10⁻⁷. Note that 28 is adjusted to 2.8 to maintain the correct form for scientific notation, which is one non-zero digit to the left of the decimal point.

Answer:

  9.89 billion

Step-by-step explanation:

At that rate of growth, the population is multiplied by 1.023 each year. After 22 years, the population would be ...

  6·1.023^22 ≈ 9.89 . . . billion

Answer:

Let the equation for the population (P) growth be given by

P = P0ert, where P0 is the initial population in billioins at time t,

                           t is the number of years since 1987,

                           r is the rate of growth of population/year

In this case P0 = 5 billion and r = 0.02.  Putting these values into the equaation:

P = 5e0.02t

Year 1995 is 8 years after 1987, then the population would be

P = 5e0.02*8 = 5e0.16 ≈ 5.87 billion people

Step-by-step explanation:

The height of the tree is 5.4 m

Step-by-step explanation:

Let the height of the tree be 'h'

Angle of elevation= 34°

distance from the rock on the ground

to the base of the tree = 8 m

we can use the tan function of trigonometry to find the height of the tree,

tan 34° = h/8

tan 34° = 0.67

tan 34° = h/8

0.67 = h/8

h = 8 x 0.67

h = 5.4m

The height of the tree is 5.4 m

The height of the tree to the nearest tenth of a meter is approximately 5.6 meters.

To calculate the height of the tree, we can use trigonometry, specifically the tangent function since we have the angle of elevation and the distance from the observer to the base of the tree.

Let's denote:

According to trigonometry,

[tex]\[ \tan(\text{angle of elevation}) = \frac{\text{height of the tree}}{\text{distance to the tree}} \][/tex]

Substituting the given values:

[tex]\[ \tan(34^\circ) = \frac{h}{8} \][/tex]

Now, let's solve for h:

h = 8 × tan(34°)

Using a calculator, we find:

h ≈ 8 × 0.6947

≈ 5.5576

Therefore, the height of the tree to the nearest tenth of a meter is approximately 5.6 meters.

|7m + 4| = 1

Answer:

95°

Step-by-step explanation:

Since, quadrilateral DUCK is inscribed in circle O

sum of the opposite angles of the quadrilateral is 180°

m<K +m<U= 180°

m<K= 180°- 85°= 95°

Answer:

95 degrees

Step-by-step explanation:

Quadrilaterals that are inscribed in circles are often called "cylic". Cyclic quadrilaterals have many unique properties. One of these is that opposite angles add up to 180 degrees.

Here, DUCK is a cyclic quadrilateral. "Opposite angles" are < U and < K, as well as < D and < C. So, since < U and < K are opposite angles in this inscribed quadrilateral, they add up to 180 degrees:

< U + < K = 180

We already know that < U = 85, so:

85 + < K = 180

< K = 95

Thus, < K is 95 degrees.

Answer: 7238.23

Step-by-step explanation:

volume of a sphere is (4/3)(pie)(r^3)

so if the diameter is 24 than the radius is 12 so u would substitute that into the formula and you should get 7238.23

The correct answer is option D: 6,912π cubic units.

To find the volume (V) of a sphere, you use the formula:

[tex]\[ V = \frac{4}{3} \pi r^3 \][/tex]

where (r) is the radius of the sphere.

Given that the sphere has a diameter of 24 units, the radius (r) is half of the diameter, which is 24/2 = 12 units.

Now, substitute the value of the radius into the formula:

[tex]\begin{aligned}V & =\frac{4}{3} \pi(12)^3 \\V & =\frac{4}{3} \pi 1728 \\V & =\frac{6912}{3} \pi\end{aligned}[/tex]

Answer:

she can put it in a bank to gain interest

she can invest in the stock market

she can loan out money

Step-by-step explanation:

Depending on the compounding frequency, Leah's investment of $12,000 with a 4.5% annual interest rate would yield the following amounts after 10 years:

- Continuous compounding: approximately $18,843.48

- Daily compounding: approximately $19,212.03

- Monthly compounding: approximately $18,867.02

Leah's inheritance presents her with a golden opportunity to grow her wealth through strategic investment. With $12,000 at her disposal, she can explore various avenues to maximize the value of her funds. One option she's considering is investing in an account that offers a 4.5% annual interest rate.

To evaluate the potential returns from this investment, she needs to understand how different compounding frequencies affect the growth of her investment over time.

Let's start by defining the equations for the amount A(t) in the account after t years, using continuous compounding, daily compounding, and monthly compounding.

1. Continuous Compounding:

The formula for continuous compounding is given by:

[tex]\[ A(t) = P \times e^{rt} \][/tex]

where:

- A(t) is the amount of money in the account after t years,

- P is the principal amount (initial investment),

- r  is the annual interest rate (expressed as a decimal),

- t is the time in years, and

- e is the base of the natural logarithm, approximately equal to 2.71828.

Using Leah's values:

P = $12,000

r = 0.045 (4.5% expressed as a decimal)

Substituting these values into the formula, we get:

[tex]\[ A(t) = 12000 \times e^{0.045t} \][/tex]

To find the amount after 10 years, we can plug t = 10  into the equation and calculate the result.

[tex]\[ A(10) = 12000 \times e^{0.045 \times 10} \][/tex]

[tex]\[ A(10) \approx 12000 \times e^{0.45} \][/tex]

[tex]\[ A(10) \approx 12000 \times 1.57029 \][/tex]

[tex]\[ A(10) \approx \$18,843.48 \][/tex]

So, after 10 years of continuous compounding, Leah's investment would be approximately $18,843.48.

Next, let's consider daily compounding. In this case, interest is compounded 365 times per year, so the formula becomes:

[tex]\[ A(t) = P \times \left(1 + \frac{r}{365}\right)^{365t} \][/tex]

Using the same values as before, we can calculate:

[tex]\[ A(10) = 12000 \times \left(1 + \frac{0.045}{365}\right)^{365 \times 10} \][/tex]

[tex]\[ A(10) \approx 12000 \times \left(1 + \frac{0.045}{365}\right)^{3650} \][/tex]

[tex]\[ A(10) \approx 12000 \times \left(1 + 0.00012328767123\right)^{3650} \][/tex]

[tex]\[ A(10) \approx 12000 \times (1.00012328767123)^{3650} \][/tex]

[tex]\[ A(10) \approx 12000 \times (1.60100220887) \][/tex]

[tex]\[ A(10) \approx \$19,212.03 \][/tex]

After 10 years of daily compounding, Leah's investment would be approximately $19,212.03.

Finally, let's explore monthly compounding. With monthly compounding, interest is compounded 12 times per year, so the formula becomes:

[tex]\[ A(t) = P \times \left(1 + \frac{r}{12}\right)^{12t} \][/tex]

Using the same values as before, we can calculate:

[tex]\[ A(10) = 12000 \times \left(1 + \frac{0.045}{12}\right)^{12 \times 10} \][/tex]

[tex]\[ A(10) \approx 12000 \times \left(1 + \frac{0.045}{12}\right)^{120} \][/tex]

[tex]\[ A(10) \approx 12000 \times \left(1 + 0.00375\right)^{120} \][/tex]

[tex]\[ A(10) \approx 12000 \times (1.00375)^{120} \][/tex]

[tex]\[ A(10) \approx 12000 \times (1.5722520173) \][/tex]

[tex]\[ A(10) \approx \$18,867.02 \][/tex]

After 10 years of monthly compounding, Leah's investment would be approximately $18,867.02.

In summary, depending on the compounding frequency, Leah's investment of $12,000 with a 4.5% annual interest rate would yield the following amounts after 10 years:

- Continuous compounding: approximately $18,843.48

- Daily compounding: approximately $19,212.03

- Monthly compounding: approximately $18,867.02

These calculations illustrate how different compounding frequencies can affect the growth of an investment over time. Daily compounding typically results in slightly higher returns compared to monthly compounding, while continuous compounding offers the highest potential returns due to its continuous nature.

By understanding these dynamics, Leah can make an informed decision about how to maximize the growth of her inheritance based on her investment preferences and goals.

The complete question is:

Leah has just inherited $12,000. She wants to invest the money so that she can increase the value of her inheritance. What are some of the ways she can do this?

1. Leah wants to invest the $12,000 in an account that pays 4.5% annual interest.

a. Write equations for the amount A(t) that will be in the account after t years, if the interest is

compounded continuously, daily, and monthly. Then, find the amount after 10 years, rounded

to the nearest cent, for each method of compounding.
