The ratio of Sam's money to Buffy's is 1.2. If Sam has $3, how much money does Buffy have? Show your work please

Let's assign variables to the unknowns to help solve the problem. Let's denote:

Paul's earnings for painting rooms as P

Paul's earnings for cutting grass as G

Megan's earnings for babysitting as M

Given information:

1. Paul earns twice as much each week painting rooms than cutting grass:

  P = 2G

2. Paul's total weekly wages are $150 more than Megan's earnings:

  P + G = M + $150

3. Megan earns one quarter as much as Paul does painting rooms:

  M = (1/4)P

Now we can solve the system of equations to find the value of P (Paul's earnings for painting rooms).

Substituting equation 2 and equation 3 into equation 1:

2G + G = (1/4)P + $150

3G = (1/4)P + $150

Substituting equation 2 into equation 3:

M = (1/4)(2G)

M = (1/2)G

Substituting the value of M in terms of G into equation 1:

3G = 4M + $150

Substituting the value of M in terms of G into equation 3:

(1/2)G = (1/4)P

Simplifying the equations:

3G = 4M + $150   (Equation A)

(1/2)G = (1/4)P   (Equation B)

Now, we can substitute the value of M in terms of G into equation A:

3G = 4[(1/2)G] + $150

3G = 2G + $150

Simplifying equation A:

G = $150

Substituting the value of G back into equation B:

(1/2)($150) = (1/4)P

$75 = (1/4)P

Multiplying both sides of the equation by 4 to solve for P:

4($75) = P

$300 = P

Therefore, Paul earns $300 for painting rooms.

The missing length n on the projection is  y.

The original triangle and its projection are similar if the three angles are the same. In this case, the missing length n on the projection can be determined by applying the concept of similarity. First, we need to find out the ratio between the lengths of the original triangle and its projection. For example, if the length of the side of the original triangle is x, and the length of its projection is y, the ratio between them is x/y.

Then, using the similar triangles theorem, we can state that the ratio between the other lengths of the original triangle and its projection is the same. This means that if we know one of the lengths, we can calculate the other one. Therefore, if the length of the side of the original triangle is x, and the ratio is x/y, then the length of the projection must be y.

Finally, we can calculate the missing length n on the projection. We know that the length of the projection is y, and we can use the ratio x/y to calculate n. Therefore, n = x*y/x, which is equal to y.

The expanded form is:

17,390,000 = 10,000,000 + 7,000,000 + 300,000 + 90,000

Step-by-step explanation:

Expanded form is a way of writing numbers with the mathematics value of digits.

Ex: 7,327 in expanded form is 7,000 + 300 + 20 + 7 = 7,327

So you can write any number in expanded form by adding the values of its digits places

Let us solve the question

The number is 17,390,000

∵ The first digit 1 is in ten-millions place

∴ Its value = 10,000,000

∵ The second digit 7 is in the millions place

∴ Its value = 7,000,000

∵ The third digit 3 is in the hundred-thousands place

∴ Its value = 300,000

∵ The fourth digit 9 is in the ten-thousands

∴ Its value = 90,000

Add all of them

∴ 17,390,000 = 10,000,000 + 7,000,000 + 300,000 + 90,000

The expanded form is

17,390,000 = 10,000,000 + 7,000,000 + 300,000 + 90,000

The probability of either of these events occurring (or both), we add the probabilities together: 1/8 + 1/8 = 1/4.

The probability that the first three flips come up heads or the last three flips come up heads (or both) can be calculated by adding the probabilities of these two events occurring separately.

To find the probability of the first three flips coming up heads, we use the formula for the probability of independent events: P(A and B) = P(A) * P(B). Since each flip is independent and has a 1/2 chance of coming up heads, the probability of the first three flips coming up heads is (1/2) * (1/2) * (1/2) = 1/8.

Similarly, the probability of the last three flips coming up heads is also 1/8.

To find the probability of either of these events occurring (or both), we add the probabilities together: 1/8 + 1/8 = 1/4.

Therefore, the correct answer is a. 1/4.

The compound interest account earns Isabella more money over the 10-year period due to the effect of compounding.

Explain compound interest

Compound interest is interest that is calculated on both the principal amount and the accumulated interest of an investment. It is essentially "interest on interest" and can result in a larger return compared to simple interest over time. The amount of interest earned is added to the principal, and the next interest calculation is based on the new, larger amount. As a result, the investment grows faster and larger over time with compounding.

According to the given information

Here's the table comparing the earnings in a simple interest account versus a compound interest account for Isabella's situation:

Account Type----------|--Formula------------------|--Interest Earned--|--Total Value

Simple Interest--------|--P*r*a------------------------|--$1,750--------------|--$5,250

Compound Interest--|--P*(1+r)ᵃ---------------------|--$2,294.64--------|--$5,794.64

Here is the time span.

Simple Interest is:

P*r*t =3500*(5/100)*10=$1,750

Total value = $3,500+$1,750=$5,250

Compound Interest is:

P*(1+r)ᵃ= 3500*(1+(5/100))¹⁰=$2,294.64

The equivalent value of m is given by the expression m = 1

Given data ,

We can use the properties of exponents to solve this problem. Specifically, when we multiply two powers with the same base, we add their exponents.

So, we have:

(-3)^(m+1) × (-3)⁵ = (-3)⁷

Using the property of exponents, we can add the exponents on the left-hand side:

(-3)^(m+1+5) = (-3)⁷

Simplifying the exponents on the left-hand side:

(-3)^(m+6) = (-3)⁷

We know that two powers with the same base are equal if and only if their exponents are equal. So, we can set the exponents equal to each other:

m + 6 = 7

Answer:

8 inches.

Step-by-step explanation:

From the statement we have that they first made two identical square pyramids, each with a base area of 100 square inches.

Ab = s ^ 2 = 100

Therefore each side would be:

s = (100) ^ (1/2)

s = 10

So, side of the square base = 10 inches

Then they tell us that they glued the bases of the pyramids together to form the precious stone. The surface area of the gemstone is 520 square inches, so for a single pyramid it would be:

Ap = 520/2 = 260

For an area of the square pyramid we have the following equation:

Ap = 2 * x * s + s ^ 2

Where x is the height of each triangular surface and s is the side of the square base

Replacing we have:

260 = 2 * x * 10 + 10 ^ 2

20 * x + 100 = 260

20 * x = 160

x = 160/20

x = 8

Therefore, the value of x is 8 inches.

Considering the known characteristics of world population growth and the observed trend in the data, a linear model is not appropriate. A nonlinear model would better represent the exponential growth pattern of the world population.

A linear model or graph may not be the best choice to illustrate this data. The reason is that the world population is known to exhibit exponential growth rather than linear growth. In a linear model, the population would increase at a constant rate over time, which is not reflective of the observed trend in the data.

Looking at the population values, we can see that they increase significantly from year to year, indicating a rapid growth rate. This suggests that a nonlinear model, such as an exponential or logarithmic model, would better capture the relationship between the years and the corresponding population.

To confirm this, we can also examine the rate of change in the population. If the rate of change is not constant, it further supports the argument against a linear model. In this case, the population growth rate is likely to vary over time due to factors like birth rates, mortality rates, and other demographic dynamics.

Therefore, considering the known characteristics of world population growth and the observed trend in the data, a linear model is not appropriate. A nonlinear model would better represent the exponential growth pattern of the world population.
