So what is a dilation and how will it effect the image and the preimage(i have 8th grade math).

Answers

Answer 1

Answer:

In geometry, a transformation is an operation that moves, flips, or changes a shape to create a new shape. A dilation is a type of transformation that enlarges or reduces a figure (called the preimage) to create a new figure (called the image).

Steve is paid overtime for all time worked past 40 hours in a week. His regular-time pay rate is $12 an hour, and his overtime pay rate is $18 an hour. Last week Steve worked 47.3 hours. 1. How many regular-time hours did Steve work? 2. How many overtime hours did he work last week? 3. What was Steve's regular-time pay last week? 4. What was Steve's gross or total pay last week?

Answers

Answer:1. 40 hours  2).7.3 hours, 3).$480 4).$611.4

Step-by-step explanation:

STEP 1

stating all requirements

regular hour = 40 hours  at $12  an hour

overtime = beyond  40 hours at $18 an hour

Step 2--- Solving out

1. Steve worked 40 regular time hours

2. Over time hours =Total 47.3 hours - 40 regular time hours = 7.3 hours

3. Regular time pay = Regular tmes hours x regular time pay rate

= 40 x $12 =$480

4) Steve gross pay = Regular time pay + overtime pay

                              = $480 + ( 7.3 hours x $18)

                              =$480+$131.4

                              =$611.4

Susan received $27 for 6 hours of work. Ricky received $14.25 for 3 hours of work. Which statement is true about there hourly rate? Answer choices: A:Susan's rate was closer to $5.00 B:Susan's rate was $0.70 more per hour C: Rickys rate was 0.25 more per hour D:Ricky was paid at half Susan's rate

Answers

Answer: C. Rickys rate was 0.25 more per hour" .

Step-by-step explanation:

Susan received $27 for 6 hours of work. Susan's rate we hour will be:

= $27/6

= $4.5

Ricky received $14.25 for 3 hours of work. Ricky's rate will be:

= $14.25/3

= $4.75

From the option given, the correct option is C "Rickys rate was 0.25 more per hour" .

This is because $4.75 - $4.5 = $0.25

The table shows what time the sunrise and
sunset occurred on dates in October. Based
on the data, what is the total number of
minutes of daylight recorded across these
dates?

Answers

Answer:

There are 2,802 minutes of daylight recorded across these dates.

Step-by-step explanation:

Elapsed Time

Elapsed time is the amount of time that passes from the start of an event to its finish.

We have to recall 1 hour has 60 minutes. Another useful fact is that from a specific time AM to the same time PM there are 12 hours or 720 minutes.

Let's find the minutes of daylight recorded day by day.

Oct, 4th:

From 7:26 am to 7:26 pm there are 720 minutes. Since the sunset time is 13 minutes less, the minutes of daylight are 720 - 13 = 707 minutes.

Oct, 6th:

From 7:27 am to 7:27 pm there are 720 minutes. Since the sunset time is 18 minutes less, the minutes of daylight are 720 - 18 = 702 minutes.

Oct, 8th:

From 7:28 am to 7:28 pm there are 720 minutes. Since the sunset time is 21 minutes less, the minutes of daylight are 720 - 21 = 699 minutes.

Oct, 10th:

From 7:30 am to 7:30 pm there are 720 minutes. Since the sunset time is 26 minutes less, the minutes of daylight are 720 - 26 = 694 minutes.

The total minutes of daylight is 707 + 702 + 699 + 694 = 2,802 minutes

There are 2,802 minutes of daylight recorded across these dates.

Answer:

This expression reminds me a lot of Fermat's last theorem x^n+y^n=z^n where n is three(odd). Which is one of many famous diophantine equations such as the well known pythagorean theorem a^2+b^2 = c^2. Where one of the variables should be even, and all are coprime. The parity is odd since it has a remainder and is not evenly divisible. It has been proven that Fermat's last theorem does not have any real solutions because you would need a complex number to cancel out the cubes. You will also see that x^n+y^n=z^n does not have any solutions if n>=3. This cannot be factored either since the numbers are rational.

Answer:

B) Exactly one solution. (-3.5)

Step-by-step explanation:

5x + 8 - 7x = -4x + 1

combine like terms

5x - 7x + 8 = -4x + 1

-2x + 8 = -4x + 1

add 4x to both sides

-2x + 4x + 8 = -4x + 1 + 4x

2x + 8 = 1

subtract 8 from both sides

2x + 8 - 8 = 1 - 8

2x = -7

divide both sides by 2.

x = -3.5

3.5, clearly, is only one number.

Set x =a-b and y=c. The formula becomes

Factoring the expression

a^2 + b^2 – c^2 + 2ab =(a^2 + 2ab + b^2) - c^2 = (a + b)^2 - c^2 =(a + b + c)(a + b - c)

Answers

Answer:

28$ more

Step-by-step explanation:

To answer this you'll need to subtract $354 out of $381.

You should get 27 (or $27).

That means that the canoe costs $27 more then the rowboat.

An object is thrown off a 256-foot-tall building, and the distance of the object from the ground is measured every second. The function that models the height, h, of the object after t seconds is h(t) = –16t2 + 96t + 256. Determine the time when the object hits the ground

Answers

Answer:

The object hits the ground 8 seconds after launch.

Step-by-step explanation:

Let [tex]h(t) =-16\cdot t^{2}+96\cdot t + 256[/tex], where [tex]h[/tex] is the height of the object above the ground, measured in feet, and [tex]t[/tex] is time, measured in seconds. We notice that given expression is a second-order polynomial and hence, there are two roots, one of them corresponding to the instant when the object hits the ground. If [tex]h(t) = 0[/tex], we get the following expression:

[tex]-16\cdot t^{2}+96\cdot t +256 = 0[/tex] (Eq. 1)

Roots are found by applying the Quadratic Formula:

[tex]t_{1,2} = \frac{-96\pm\sqrt{96^{2}-4\cdot (-16)\cdot (256)}}{2\cdot (-16)}[/tex]

[tex]t_1 = 8\,s[/tex] or [tex]t_{2} = -2[/tex]

Only the first root offer a solution that is physically reasonable. Thus, the object hits the ground 8 seconds after launch.

Which of the following happens when 21.63 is multiplied by 10^3?

A. The digit in the tens place moves to the hundredths place.
B. The digit in the tens place moves to the thousandths place.
C. The digit in the hundredths place moves to the tens place.
D. The digit in the hundredths place moves to the hundreds place

Answers

Answer: C. The digit in the hundredths place moves to the tens place.

Step-by-step explanation:

In 21.63,

place value of 2 = tens

Place value of 1 = ones

Place value of 6 = tenths

Place value of 3 = hundredths

21.63 × 10^3 = 21.63 × 1000 = 21630

From here , we can see that the digit in the hundredths place which is 3 has moved to the tens place.

Therefore, C is the answer.

The local meteorologist claims that the temperature is going to steadily drop over the next 4 hours. If the temperature changes by the same amount each hour, and it changes by a total of -28°F, how much will it change each hour? Explain how you got your answer in two or more complete sentences. plz answer with a real answer will give brainlyest

Answers

Answer:

-7°F/hour.

Step-by-step explanation:

If the total change is -28°F, and we know it took 4 hours, we just have to divide the total change by hours taken to get the change per hour.

So we do the following: [tex]\frac{-28F}{4} = -7F/h[/tex]

So the temperature changes (drops) by -7°F/hour.

A culture of bacteria has an initial population of 12000 bacteria and doubles every 6 hours. Using the formula P_t = P_0\cdot 2^{\frac{t}{d}}P t ​ =P 0 ​ ⋅2 d t ​ , where P_tP t ​ is the population after t hours, P_0P 0 ​ is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 17 hours, to the nearest whole number?

Answers

Answer:

85,524 bacteria

Step-by-step explanation:

Given the population of bacteria modelled by the equation where;

[tex]P_t = P_0\cdot 2^{\frac{t}{d}[/tex]

P0 is the initial population

t is the time in hours

d is the doubling time

If the culture of bacteria has an initial population of 12000 bacteria, this means that;

at t = 0, P0 = 12000

substitute into the modelled function

[tex]P_t = P_0\cdot 2^{\frac{t}{d}\\\\P_t = 12000\cdot 2^{\frac{0}{d}\\\\\\P_t =12000\cdot 2^{0}\\\\P_t = 12000[/tex]

If the population doubles every 6 hours

at t = 6, Pt = 24000

[tex]P_t = P_0\cdot 2^{\frac{t}{d}\\\\\\24000 = 12000\cdot 2^{\frac{6}{d}\\\\\\\\24000/12000 = 2^{\frac{6}{d}\\\\\\\\[/tex]

[tex]2 = 2^{\frac{6}{d} }\\1 = 6/d\\d = 6\\[/tex]

Next is to get the population of bacteria in the culture after 17 hours

at t = 17, Pt = ?

[tex]P_t = P_0\cdot 2^{\frac{t}{d}\\\\P_t = 12000\cdot 2^{\frac{17}{6}\\\\\\\\P_t = 12000\cdot 2^{ 2.833 }\\P_t = 12000\cdot 2^{ 2.833 }\\P_t = 12000 * 7.127\\P_t = 85,524.3[/tex]

Hence the population of bacteria in the culture after 17 hours, to the nearest whole number is 85,524 bacteria
