Each time Gertrude gets paid, 10% of her pay check goes to taxes. Last week, $ 40 was taken out of her check for taxes. What was the amount of Gertrude's pay check last week?

Answers

Answer 1

The answer is 400. every 10% equal 100

Answer 2

Final answer:

Gertrude's paycheck last week was $400.

Explanation:

To find the amount of Gertrude's paycheck last week, we can set up an equation using the information given. Let's assume her paycheck amount is represented by 'x'. According to the problem, 10% of her paycheck, or 0.10x, is taken out for taxes. This amount is given as $40. So we can write the equation as 0.10x = 40. To solve for x, we divide both sides of the equation by 0.10: x = 40 / 0.10 = $400.

Answers

Sunday's high temp was 3 degrees warmer than Tuesdays

Answer: It means the high temperature of Sunday is 3 degrees warmer than the high temperature of Tuesday.

Step-by-step explanation:

Let the temperature on Sunday be 'x'.

So, Temperature of Monday would be

The observations you made in the unit circle can help you determine the x‑ and y‑coordinates of special points on the circle without memorizing the circle. Analyze some of the patterns by completing the parts below.
a. Look at all the ordered pairs whose angles are of the form k pi/4, where k is an integer. What do you notice?
b.Now look at the ordered pairs whose angles are of the form k pi/6 or k pi/3. What do you notice about their coordinates?
c.How can you determine if the coordinates of a point are positive or negative?

Answers

a. Look at all the ordered pairs whose angles are of the form k pi/4, where k is an integer. What do you notice? These ordered pairs would be found along the lines that make 45 deg, 135 deg, 225 deg and 270 deg angles as measured from the positive x-axis. Every such line is made up of an infinite number of dots representing such pairs. And the x- and y-components of these pairs would be equal in magnitude (but could have different signs).

The table gives estimates of the world population, in millions, from 1750 to 2000. year population year population 1750 790 1900 1650 1800 980 1950 2560 1850 1260 2000 6080 (a) use the exponential model and the population figures for 1750 and 1800 to predict the world population in 1900 and 1950. compare with the actual figures

Answers

The exponential model provides a reasonable approximation for the world population growth between 1750 and 1800. However, it becomes less accurate for longer time periods due to various factors like technological advancements, medical breakthroughs, and changing social and economic conditions.

1. Define the model:

The general form of an exponential model is:

P(t) = a * b^(t)

where:

P(t) is the population at time t

a is the initial population (at t = 0)

b is the growth factor (greater than 1 for positive growth)

t is the time elapsed (in years, since the initial time)

2. Find the parameters:

We have data for 1750 (t = 0) and 1800 (t = 50):

P(0) = 790 million (initial population)

P(50) = 980 million (population after 50 years)

Using these values, we can solve for a and b:

b = (P(50) / P(0))^(1/t) = 980 / 790)^(1/50) ≈ 1.007

a = P(0) / b^0 = 790 / 1 ≈ 790

3. Predict the population in 1900 and 1950:

Now we can plug the values of a and b into the model to predict the population:

P(150) = 790 * 1.007^(150) ≈ 1912 million (predicted population in 1900)

P(200) = 790 * 1.007^(200) ≈ 3145 million (predicted population in 1950)

4. Comparison with actual data:

The actual population in 1900 was 1650 million and in 1950 was 2560 million. While the model overestimates the population in both cases, it still captures the general trend of growth.

A square sheet of art paper has an area of 625 square inches. What is the minimum side length of an easel that supports the whole sheet of paper?

Answers

If the area of the paper is 625 sq in, the length of one side of this square is sqrt(625 sq in), or 25 inches. That's the min. side length of an easel that is to support the whole sheet of paper along its lowest side.

area of a square = side^2

to find the length of a side using area find the square root of the area

sqrt(625) = 25

so the easel has to be at least 25 inches

Robin's family breeds Great Danes. In the last litter, one of the puppies grew at an unusually consistent rate. At birth, he weighed two pounds. At eight months, he weighed 110 pounds.

Answers

Let's assume that you're being asked to write a formula for the dog's weight.

In this case, w = (weight after x months) = (initial weight) (1 + r)^x

We know the initial and final weights: 2 lb and 110 lb. We also know that the time period involved is 8 months. What is the "consistent" rate at which the dog gains weight?

110 lb = (2 lb) (1 + r)^8

Let's solve this for r.

Dividing both sides by 2 lb, 55 = (1 + r)^8

Finding the 8th root of both sides: 1.65 = 1 + r

Solving for r, r = 0.65

The dog gains weight at the consistent rate of 0.65 lb/month.

Check: Does (2 lb) (1.65)^8 come out to 110 lb?

(2 lb)(54.94) = 109.9 lb (very close indeed to 110 lb).

Answer:

A. An additional month of growth is associated with an additional 13.5 pounds of weight.

Jared used one whole number 2/5 of soil for his garden. He is digging another garden that will need 1/5 as much soil as the original. How much will he use total.

Answers

Assuming "one whole number 2/5 of soil for his garden" mean 1+2/5(equal to 7/5) then 1/5 of the original garden soil would be:
1/5 * 7/5 = 7/25

Then you need to add the first sum(7/5) with the second sum(7/25) to get the total soil. The calculation would look like this:
7/5 + 7/25= 35/25 + 7/25= 42/25= 1 + 17/25

Find the extreme values of f subject to both constraints f(x,y) = 2x^2+3y^2-4x-5, x^2 + y^2 <=16

Answers

[tex]f(x,y)=2x^2+3y^2-4x-5[/tex]
[tex]f_x=4x-4=0\implies x=1[/tex]
[tex]f_y=6y=0\implies y=0[/tex]

[tex]f(x,y)[/tex] has only one critical point at [tex](x,y)=(1,0)[/tex]. The function has Hessian

[tex]\mathbf H(x,y)=\begin{bmatrix}f_{xx}&f_{xy}\\f_{yx}&f_{yy}\end{bmatrix}=\begin{bmatrix}4&0\\0&6\end{bmatrix}[/tex]

which is positive definite for all [tex](x,y)[/tex], which means [tex]f(x,y)[/tex] attains a minimum at the critical point with a value of [tex]f(1,0)=-7[/tex].

To find the extrema (if any) along the boundary, parameterize it by [tex]x=4\cos t[/tex] and [tex]y=4\sin t[/tex], with [tex]0\le t<2\pi[/tex]. On the boundary, we have

[tex]f(x(t),y(t))=F(t)=2(4\cos t)^2+3(4\sin t)^2-4(4\cos t)-5=32\cos^2t+48\sin^2t-16\cos t-5[/tex]
[tex]F(t)=35-16\cos t-8\cos2t[/tex]

Find the critical points along the boundary:

[tex]F'(t)=16\sin t+16\sin2t=16\sin t+32\sin t\cos t=16\sin t(1+2\cos t)=0[/tex]
[tex]\implies t=0,\dfrac{2\pi}3,\pi,\dfrac{4\pi}3[/tex]

Respectively, plugging these values into [tex]F(t)[/tex] gives 11, 47, 43, and 47. We omit the first and third, as we can see the absolute extrema occur when [tex]F(t)=47[/tex].

Now, solve for [tex]x,y[/tex] for both cases:

[tex]t=\dfrac{2\pi}3\implies\begin{cases}x=4\cos t=-2\\y=4\sin t=2\sqrt3\end{cases}[/tex]

[tex]t=\dfrac{4\pi}3\implies\begin{cases}x=4\cos t=-2\\y=4\sin t=-2\sqrt3\end{cases}[/tex]

so [tex]f(x,y)[/tex] has two absolute maxima at [tex](x,y)=(-2,\pm2\sqrt3)[/tex] with the same value of 47.

what is the rule for solving proportions? A. The sum of the means is the product of the extremes. B. The product of the means is equal to the product of the extremes. C. The product of the extremes is twice the product of the means.

Answers

The rule is that :
B. The product of the means is equal to the product of the extremes

Final answer:

The rule for solving proportions is that the product of the means equals the product of the extremes. This method is used when dealing with categorical data in two categories.

Explanation:

The rule for solving proportions is this: The product of the means is equal to the product of the extremes (option B). When you have a proportion which is often written in the mathematically form 'a/b = c/d', you can use this rule. 'a' and 'd' are the extremes and 'b' and 'c' are the means. Therefore, the rule means that a*d (product of the extremes) is equal to b*c (product of the means).

In terms of identifying when you're dealing with a proportion problem, you're involved in this scenario when the data you're dealing with is of two categories like Yes or No, Success or Failure. This is typically when you're attempting to estimate a population proportion for example, the proportion of the population that smokes or will vote for candidate A.
