Please help: If the area of a rectangular picture of a stamp is 81 times greater than the actual stamp's area, and the stamp has a length of 4/3". what is the length of the stamp's picture?​
I know the answer is 12 inches but not sure how to get there so pls explain

Answers

Answer:

12 inches.

Step-by-step explanation:

We know that the length of the stamp is 4/3 inches.

Let the width be x inches.

Then the area of the actual stamp is:

[tex]\frac{4}{3}x\text{ inches}^2[/tex]

We know that the rectangular picture of the stamp is 81 times greater than the actual stamp’s area. Therefore, the area of the picture is 81 times the above. So:

[tex]81(\frac{4}{3}x)\text{ inches}^2[/tex]

So, the area of the rectangular picture is the area of the actual stamp multiplied by a scale factor k.

When we use the scale factor to scale area, we need to square it. Hence, the area of the actual stamp times the scale factor squared is equal to the area of the rectangular picture. Therefore:

[tex]\frac{4}{3}x(k^2)=81(\frac{4}{3}x)[/tex]

Let’s solve for the scale factor. Divide both sides by 4/3(x). Hence:

[tex]k^2=81[/tex]

Take the square root of both sides:

[tex]k=9[/tex]

So, the scale factor from the actual stamp to the picture is 9.

So, the actual stamp has a length of 4/3.

Then ThThe length of the stamp’s picture will be:

[tex]\frac{4}{3}k[/tex]

Substitute 9 in for k to get:

[tex]=\frac{4}{3}(9)=12[/tex]

So, the length of the stamp’s picture is 12 inches.

A recipe uses 3 cups of flour 2 cups of sugar write the ratio of flour to sugar. Then write the related rate and unit rate.

Answers

The ratio of a certain thing say A to another B is written as A:BTo write this as a rate, put the left value A on top of the right value B so that [tex]A:B=\frac{A}{B}[/tex] So the rate is [tex]\frac{(3)cupsofflour}{(2)cupsofsugar}[/tex]  read as 3 cups of flour per 2 cups of sugarThe unit rate means write the fraction as a rational non-fraction number so [tex]\frac{3}{2}=1.5\\so\\(\frac{3}{2})cupsofflour/cupsofsugar = (1.5)cupsofflour/cupsofsugar[/tex]

The freefall function to calculate velocity, v, of an object that begins at rest and falls for distance d is v(d) = 2gd , where g is the acceleration due to gravity. The Storm Runner roller coaster at Hershey Park drops 55 m. Use the free-fall function to calculate to the nearest tenth its velocity at the end of the freefall. Use g = 9.8 m/s2 Enter your answer, rounded to the nearest tenth, in the box. v(55) = m/s​

Answers

Answer:

  32.8 m/s

Step-by-step explanation:

The function is actually ...

  [tex]v(d) = \sqrt{2gd}[/tex]

Filling in the given values, the velocity is about ...

  [tex]v(55) = \sqrt{2\cdot9.8\cdot55}=\sqrt{1078}\approx32.8\text{ m/s}[/tex]

The velocity at the end of the free-fall is about 32.8 meters per second.

Jesse recorded the temperatures at which two oils freeze: Oil Temperature Sesame oil −6.2 °C Peanut oil 3.1 °C Which statement about the temperatures at which these oils freeze is true? Sesame oil freezes at a higher temperature than peanut oil because −6.2 °C < 3.1 °C. Sesame oil freezes at a lower temperature than peanut oil because −6.2 °C < 3.1 °C. Sesame oil freezes at a higher temperature than peanut oil because −6.2 °C > 3.1 °C. Sesame oil freezes at a lower temperature than peanut oil because −6.2 °C > 3.1 °C. plzzz answer this for me ^w^

Answers

Answer: C. Sesame oil freezes at a lower temperature than peanut oil because −6.2 °C < 3.1 °C

Step-by-step explanation:

Given that:

Freezing point of sesame oil = - 6.2°C

Freezing point of peanut oil = 3.1°C

Comparing the two temperatures :

Freezing(when a substance turns to solid) usually occurs at low temperatures. The temperature of sesame oil(-6 2°C) is lower than that of peanut oil(3.1°C).

Hence, it can be concluded that Sesame oil freezes at lower temperature than peanut oil.

Mathematically,

-6.2°C < 3.1°C

Answer:

Answer: C. Sesame oil freezes at a lower temperature than peanut oil because −6.2 °C < 3.1 °C

Determine the result

Following Charlie's steps:

0.09 is a 2 decimal placed digit

and

0.05 is a 2 decimal placed digit

So, the product is as follows:

9 --------- 2 decimal place

In one year, the population of Douglas, the former copper mining town on the U.S.-Mexico border, shrunk by 200. Over the last ten years, the town's population is going down at an average rate of 1.16% per year. Douglas' current population in November 2020 is 15,140.

Answers

Complete question :

In one year, the population of Douglas, the former copper mining town on the U.S.-Mexico border, shrunk by 200. Over the last ten years, the town’s population is going down at an average rate of 1.16% per year. Douglas’ current population in November 2020 is 15,140. a. Write an equation to model the population decay of Douglas using the data given. b. If the town’s population loss continues to occur at this rate, what will the population of Douglas in 6 months from now? Round your answer to the nearest integer. c. If the town’s population loss continues to occur at this rate, what will the population of Douglas in one year? Round your answer to the nearest integer. d. If the town’s population loss continues to occur at this rate, what will the population of Douglas in November 2027? Round your answer to the nearest integer.

Answer:

15052 ; 14,964 ; 13953

Step-by-step explanation:

Given that:

Rate of population decline = 1.16% annually

Population in November 2020 = 15140

A = I(1 - r)^t

Where ;

A = final population

I = initial population

r = rate of decline

t = number of years

Population in 6 months

t = 6 months = 0.5 year, r = 1.16% = 0.0116

A = 15140(1 - 0.0116)^0.5

A = 15140(0.9884)^0.5

A = 15051.931

A = 15052 ( nearest integer)

Population after 1 year :

A = 15140(1 - 0.0116)^1

A = 15140(0.9884)^1

A = 14964.376

A = 14964 ( nearest integer)

Population in 2027:

t = 2027 - 2020

A = 15140(1 - 0.0116)^7

A = 15140(0.9884)^7

A = 13952.596

A = 13953 ( nearest integer)

3(3k-10)+1=8(3/2k+2) show work

Answers

Answer:

k=−15

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(3k−10)+1=8( 3 /2 k+2)

(3)(3k)+(3)(−10)+1=(8)( 3 /2 k)+(8)(2)(Distribute)

9k+−30+1=12k+16

(9k)+(−30+1)=12k+16(Combine Like Terms)

9k+−29=12k+16

9k−29=12k+16

Step 2: Subtract 12k from both sides.

9k−29−12k=12k+16−12k

−3k−29=16

Step 3: Add 29 to both sides.

−3k−29+29=16+29

−3k=45

Step 4: Divide both sides by -3.

−3k /−3 = 45 /−3

k=−15
