The conditional, "If you work 20 hours a week, then you would make $125.00" would be false if this holds true:

c. You work 20 hours a week, and you make $175.00

To arrive at the wrong conclusion, we need to look out for the statement that directly violates the hypothesis that working 20 hours a week will yield $125.

The answer that is in direct conflict with this statement is option C. Here, instead of making $125, the person makes $175 and this is way above the conclusion reached in the original sentence. So, the wrong conditional is C.

In the given word problem amount does Teresa spends is $16.50.

A math word problem is a question that is written as one or more sentences and asks students to use their mathematical understanding to solve an issue from "real world." In order  to understand the word problem, they must be familiar with the terminology that goes along with the mathematical symbols that they are used to.

Here,

The amount does Jayson Spends = $3.75

According to the question,

Myra spends 3times as much as Jayson . then

Amount does Myra spends = 3× 3.75 = $11.25.

Now Teresa spends $5.25 more than Myra then,

Amount does Teresa spends = 11.25+5.25 = $ 16.50.

Therefore , the solution of the given problem of area is largest map that may be utilized while still fitting on the page is 20/3 inches by 10 inches.

The term "area" refers to how much room a 2D structure or surface occupies. We use these units to measure surface in cm2 or m2. By dividing the length by the breadth of a form, you can determine its area.

Area = length times breadth and Perimeter = 2 (length + width)

Here,

Given: 2 feet by 3 feet is the size of the map.

8 by 10 inches is the size of a sheet of paper; in inches:

12 inches per foot

24 inches are equal to two feet, or two times twelve.

36 inches are equal to three feet, or three times twelve.

Scale factor is 24/36, or two-thirds.

Paper's longer side equals ten inches.

Using the scale, determine how long the shorter side is:

2/3 = x/10

the cross-multiply

3x = 2 × 10

3x = 20

x = (20 ÷ 3)

Answer:

y = -2x

Step-by-step explanation:

The equation is y = mx +b

m = the slope

b = y-intercept

The slope = rise/run

Let's pick 2 points (0,0) (2,-4); we see the y decrease by 4 and the x increase by 2, so our slope is

m = -4/2 = -2

Y-intercept is when x = 0, y-intercept is located at (0,0)

So our equation is

y = -2x

Answer:

Step-by-step explanation:

J:  y = 29 cm + (1 cm/mo)x

Z:  y = 12 cm + (2 cm/mo)x

29 cm + (1 cm/mo)x =  12 cm + (2 cm/mo)x

Solve for x to find how many months it will take for them to have the same length of hair:

29 cm - 12 cm = (2 cm/mo)x - (1 cm/mo)x

17 cm = (1 cm/mo)x

x = (17 cm) / (1 cm/mo) = 17 months

Plug this value for x (17 months) into the equations to find how long their hair will be:

J:  y = 29 cm + (1 cm/mo)(17 mo) = 46 cm

Z:  y = 12 cm + (2 cm/mo)(17 mo) = 46 cm

This shows that it will take 17 months for each girl's hair to be 46 cm long.

The number of mandarins in the bag is 3 * 33 + 3 = 102 mandarins.

This is a Diophantine equation problem, which is a type of mathematical problem that looks for integers that satisfy a given equation.

We know that the number of mandarins in the bag is equal to 4n + 3, 5m + 2 and 6p + 3 and 7q + 3 for some integers n, m, p and q.

We also know that the number of mandarins in the bag is equal to 3r, where r is an integer.

From the information provided, we can set up the following equation:

4n + 3 = 5m + 2 = 6p + 3 = 7q + 3 = 3r

Now we can use the information that when he finally put them into 3 piles and he didn't have any left over, meaning that the number of mandarins in the bag is divisible by 3, we can see that the remaining number in each case is 3.

Thus the number of mandarins in the bag is 3 * (some integer) + 3.

We can then use the information that the number of mandarins in the bag was less than 100, meaning the possible value of r is less than 34.

Testing values of r starting from 1, we can see that r = 33 satisfies the equation and the number of mandarins in the bag is 3 * 33 + 3 = 102 mandarins

y-intercept = (0, 2).

Furthermore, the x-intercept and y-intercept of function g include the following:

  x = -2 and 4

Step-by-step explanation:

You want a plot of the x-intercepts of H(x) = (x -1)² -9.

The x-intercepts are the points where the graph crosses the x-axis, the points where H(x) = 0. Solving, we get ...

  H(x) = (x -1)² -9

  9 = (x -1)² . . . . . . . . add 9

  ±3 = x -1 . . . . . take the square root

  ±3 +1 = x = {-2, 4} . . . . . add 1

The attached graph shows the coordinates of the x-intercept points on the x-axis. The coordinates of the vertex of the parabola are also shown.

The area between the x-axis and y = x from x = 3 to x = 6 will be 13.50 square feet.

Integration is a way of finding the total by adding or summing the components. It's a reversal of differentiation, in which we break down functions into pieces. This approach is used to calculate the total on a large scale.

The function is given below.

y = x

Integrate the function under the limit from  x = 3 to x = 6 will be given as,

Simplify the equation further, then we have

I = (36 - 9) / 2

I = 27 / 2

Answer:

180.4 is 140.9% of 128.

Step-by-step explanation:

180.4 is what percent of 128 Rounded to the nearest tenth?

=========================================================

Explanation:

Part A

x = number of years after 1983

Example: x = 2 is the year 1985 since 1985-1983 = 2.

The number of people who drink this beverage declines by 6.5% each year. The multiplier is 1+r = 1+(-0.065) = 0.935

Meaning that if 6.5% of the people leave, then 93.5% remain. The two percentages add to 100%.

This value 0.935 is the base of the exponent portion. We have 0.935^x as the exponent portion.

Out front is the value 5480 which is the starting amount of people.

This leads to the exponential equation y = 5480*0.935^x

It is of the form y = ab^x

a = 5480 = starting population

b = 0.935 = decay factor

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

Part B

The timespan from 1983 to 2023 is 40 years (because 2023-1983 = 40).

Which means we plug x = 40 into the equation we found in part A.

y = 5480*0.935^x

y = 5480*0.935^40

y = 5480*0.06799303620922

y = 372.601838426526

y = 373

Be sure to round to the nearest whole number.

We expect or predict there will be approximately 373 people who remain loyalists to this root beer as of September 2023.

The initial number of people who drink Root Beer (in September 1983):

If the number of people that drink Root Beer instead of Coca-Cola has been declining at the rate of 6.5% per year, then:

Therefore, an exponential equation that represents the number of Root Beer loyalists in Outback for any year is:

where:

The number of years between September 1983 and September 2023 is:

To calculate how many Root Beer loyalists should there be as of September 2023, substitute x = 40 into the equation found in part (a):

[tex]\implies y=5480(0.935)^{40}[/tex]

[tex]\implies y=5480(0.0679930362...)[/tex]

Answer:

56 pages per hour

Step-by-step explanation:

Penny reads 14 pages in 1/4 of an hour.

An hour is 4 times more than 1/4 of an hour (you could think of it as 15 minutes compared to 60 minutes)

Multiply the amount penny reads in 1/4 of an hour (14 pages) by 4 to get the rate she reads in 1 hour.

14 x 4 = 56

Now add the rate of time (per hour) to get that she reads a total of 56 pages per hour.
