Answer:
answer and explanation in pics above
if u have any questions , pls list them in comments
Answer:
Y= 3
Step-by-step explanation:
To do this u can subtract -4 on each side. Whatever u do to one side of the equal sign u have to do to the other.
+4 and -4 cancel each other out
-11 + -4 = -15
The next step is to divide -5y on each side.
-5y divide by negative -5y cancel each other out leaving the y isolated.
-15 divided by -5 gives u positive 3.
So the answer is y=3

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
Step-by-step explanation:
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)
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.

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

At the Howelton Hot Dog Happiness competition, Olaf eats five fewer than triple the hot dogs Alfred eats. Olaf eats 67 hot dogs. Alfred eats "a" hot dogs. How many does Alfred eat? Have to do PEMDAS backwards, just need help setting up the equation.
Answer:
Alfred ate 24 hot dogs.
Step-by-step explanation:
Let the number of hot dog ate by Olafs be represented by b.
Since Olafs eats five fewer than triple the hot dogs Alfred eats, and Alfred ate a hot dogs. This can be expressed in a mathematical equation as follows;
b = 3a - 5
But Olafs eats 67 hot dogs, so that b = 67. Thus;
b = 3a - 5
67 = 3a - 5
67 + 5 = 3a
3a = 72
divide both sides by 3 to have;
a = [tex]\frac{72}{3}[/tex]
a = 24
Alfred ate 24 hot dogs.

The total profit from the Spanish club fund-raiser varies directly with the number of dinner tickets sold. If the sale of 22 tickets results in a profit of $253, how many tickets must be sold to reach the fund-raising goal of $700 ?
Answer:
61 tickets
Step-by-step explanation:
It is given that,
The total profit from the Spanish club fund-raiser varies directly with the number of dinner tickets sold.
If the sale of 22 tickets results in a profit of $253.
Profit in 1 ticket = [tex]\dfrac{253}{22}=\$11.5[/tex]
Let x tickets are sold in order to reach the fund-raising goal of $700.
[tex]x=\dfrac{22}{253}\cdot700\\\\=\$60.86[/tex]
or
= 61 tickets
Hence, 61 tickets must be sold to reach the fund-raising goal of $700.

Consider the growth function f(x)=200(1.08). Describe the characteristics of the functions by using the drag and drop feature
Answer:
1) Domain: -∞ < x < +∞
2) Range: y > 0
3) y intercept: (0, 200)
4) Asymptote: y = 0
5) The growth rate; r = 0.08
6) The growth factor = 1.08
7) End Behavior: As x → -∞, f(x) → 0
8) End Behavior: As x → +∞, f(x) → +∞
Step-by-step explanation:
1) The domain of the function is given as the x values for which the function is valid which includes from -∞ < x to +∞
2) The range of the function, are the range of the output values of the function for the given range of the input values
For the function, f(x) = 200·(1.08)ˣ, we have, f(x) = y > 0, for all values of x
3) The y-intercept is the value of y, when x = 0, given as follows;
y intercept = f(0) = 200·(1.08)⁰ = 200 × 1 = 200
4) The asymptote is the line that the function approaches but never reaches
In the question, as x tends to -∞, the function f(x) approaches 0. Therefore, f(x) = y = 0 is the asymptote of the function
5) The growth rate of an exponential function, y = a(1 + r)ˣ is r
Therefore, for the function, 200·(1.08)ˣ, which is equivalent to 200·(1 + 0.08) ˣ, the growth rate = 0.08
6) The growth factor of an exponential function, y = a(1 + r)ˣ is (1 + r)
Therefore, for the function, 200·(1.08)ˣ, which is equivalent to 200·(1 + 0.08) ˣ, the growth factor = (1 + 0.08) = 1.08
7) The end behavior as x tends to -∞, [tex]f(x) = y= 200 \cdot (1.08) ^{-\infty} \rightarrow 0[/tex]
8) The end behavior as x tends to +∞, [tex]f(x) = y= 200 \cdot (1.08) ^{-#+\infty} \rightarrow + \infty[/tex]
The texts that complete the blanks are:
Domain: -∞ < x < +∞Range: y > 0y intercept: (0, 200)Asymptote: y = 0The growth rate; r = 0.08The growth factor = 1.08End Behavior: As x → -∞, f(x) → 0End Behavior: As x → +∞, f(x) → +∞The domain
The domain of an exponential function is all set of real numbers.
So, the domain is: -∞ < x < +∞
The range
The range of an exponential function is always greater than 0.
So, the range is y > 0
The y-intercept
This is when x = 0.
So, we have:
[tex]f(x) = 200(1.08)^x[/tex]
This gives
[tex]f(0) = 200(1.08)^0[/tex]
[tex]f(0) = 200[/tex]
So, the y-intercept is (0,200)
The asymptote
This is the line that is close to the function but is not on the function.
The range is:
y > 0.
So, the asymptote is y = 0
The growth rate and the growth factor
The function is given as:
[tex]f(x) = 200(1.08)^x[/tex]
The growth factor is 1.08, while the growth rate (r) is calculated as:
[tex]r = 1.08 - 1[/tex]
[tex]r = 0.08[/tex]
Hence, the growth rate is 0.08, and the growth factor is 1.08
The end behavior
The end behavior of an exponential growth function is:
a x → -∞, f(x) → 0 and as x → +∞, f(x) → +∞
