Answer:
$1.25 dollars per day added to the coin jar
Step-by-step explanation:
the given equation is: 56 – 4y = –5x
we can rewrite it:
4y = 56 + 5x
y = (56 + 5x) / 4
y = 14 + ⁵/₄x
the slope of the equation is ⁵/₄, which gives us how much money is added into the coin jar every day. We can write ⁵/₄ as 1.25 or $1.25 dollars per day added to the coin jar

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
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.
Can you tell me the slope for each graph i got the first 2
answers are at the bottom
Answer: 1) m=2, 2) m=-2/3, 3) m=-2/5 4) m=-1/2 5) m=4 6) m=1
Step-by-step explanation:
2, 3, & 4 are all declining so they are going to be negative and 1, 5, & 6 are all inclining so they’re positive. When you put the amount you go up vertically from point to point over the amount you travel horizontally between each point you should get the slope for each graph.

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

Charlie is evaluating the product of 0.09 and 0.05. He multiplies, and before placing the decimal, arrives at an answer of 45. After considering the decimal placement, what is Charlie's final answer?
Answer:
Result = 0.0045
Step-by-step explanation:
Given
[tex]0.09 * 0.05[/tex]
Required
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
5 --------- 2 decimal place
------------------------------------------
45 --------- 4 decimal place
Shifting the decimals in 45 to 4 decimal places will give us: 0.0045
Hence, the final answer is 0.0045

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^
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

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.
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)

Find the slope.
Anybody can help me ?
Answer: -2/7
Step-by-step explanation:
Consider the function f(x) = 3x − 2. Select True or False for each statement. The y-intercept is 2. A True B False The x-intercept is 2 3 . A True B False The slope is 3. A True B False
Answer: A false, B true, C true
Step-by-step explanation:
A) intercept with y axis
That means x=0
y= 3*0-2
y= -2 So A is false
B) intercept with x axis
That means y=0
0= 3x-2
2=3x
2/3= x B is true
C) The form of linear function is
f(x)= mx +n, where m is the slope
In this case m= 3 so C is true
1. The y - intercept is 2. ⇒ False
2. The x - intercept is 2/3 ⇒ True.
3. The slope is 3. ⇒ True.
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The function is,
f (x) = 3x - 2
Now,
1. To find the y - intercept we substitute x = 0 in the function.
Hence, The y - intercept is,
f (x) = 0 - 2
f (x) = - 2
Hence, The statement y - intercept is 2 is False.
2. To find the x - intercept we substitute f(x) = 0 in the function.
Hence, The y - intercept is,
f (x) = 3x - 2
0 = 3x - 2
3x = 2
x = 2/3.
Hence, The statement x - intercept is 2/3 is True.
3. We know that;
The slope intercept form of the line is,
y = mx + b
Where, m is slope of the line.
And, b is y - intercept.
So, By comparing with the function f (x) = 3x - 2 , we get;
Slope (m) = 3
Hence, The slope is 3 is True.
