Answer:
the slope is -1/3
the Y intercept is 10/3
Step-by-step explanation:
Answer:
-1/3
Step-by-step explanation:
We want to get the equation in slope intercept form (y=mx+b) where m is the slope and b is the y intercept
x+3y = 10
Subtract x from each side
x-x+3y = -x+10
3y = -x+10
Divide each side by 3
3y/3 = -1/3x +10/3
y = -1/3x +10/3
The slope is -1/3 and the y intercept is 10/3

How to find the median
To find the median of a data set, you need to arrange the data in ascending order (from smallest to largest) and then find the middle value.
In the stem and leaf plot, we have to express the numbers as follows
50 53 65 64 75 77 78 82 84 85 86 87 87 90 91 92 93 94 96 97 99
The data set is 21. The meidan is the number in the middle. This will be the 11 position in this case
The number in the 11th positon here is 86
Find the surface area of the right square pyramid. Round your answer to the nearest hundredth.
ANSWER
C. 145.75 yd²
EXPLANATION
First we need to calculate the area of the four triangular faces.
The lateral surface area
[tex] = 4 \times \frac{1}{2} \times 5.3 \times 11.1[/tex]
[tex] = 117.66 {yd}^{2} [/tex]
The area of the base is
[tex] = 5.3 \times 5.3[/tex]
[tex] = 28.09[/tex]
To find the total surface area, we add the area of the square base to the area of the 4 triangular faces.
Therefore the total surface area is
[tex] = 117.66 + 8.09 = 145.75 {yd}^{2} [/tex]
Answer: Option C.
Step-by-step explanation:
To calculate the surface area of the right square pyramid, you need to use the following formula:
[tex]SA=\frac{1}{2}(4s)(l)+(s^2)[/tex]
Where "s" is the length of any side of the base and "l" is the slant height.
You can identify in the figure that:
[tex]s=5.3yd\\l=11.1yd[/tex]
Therefore, substituting these values into the formula, you get this result:
[tex]SA=\frac{1}{2}(4(5.3yd))(11.1yd)+((5.3yd)^2)\\\\SA=145.75yd^2[/tex]
A store marks up merchandise 40% to make a profit. If the item costs the store $12, what is the selling price?
Answer:
$16.80
Step-by-step explanation:
The item costs the store $12.00
12 x 40% or 12 x 0.4 = 4.8
Add 4.8 to 12
And you get the price the store sells the product for profit, $16.80
A cabin cruiser travels 48 miles upstream (against the current) and 48 miles downstream (with the current). The speed of the current is 4 miles per hour. Find the total time traveled if the cabin cruiser travels at 12 miles per hour in still water.
The answer is:
The total time traveled is equal to 9 hours.
Why?To solve the problem, we need to write two equations using the given information about the travel upstream and downstream.
So, we need to write two equations:
Let be "x" the speed of the cabin cruiser (12 mph in still water)
Let be "y" the speed of the current (4 mph).
Then,
For the travel against the current (upstream), we have:
[tex](x-y)*t_{upstream}=48miles\\\\(x-y)*t_{upstream}=48miles\\\\(x-4mph)*t_{upstream}=48miles[/tex]
For the travel with the current (downstream), we have:
[tex](x+y)*t_{downstream}=48miles\\\\(x+y)*t_{downstream}=48miles\\\\(x+4mph)*t_{downstream}=48miles[/tex]
Also, we know that the speed of the cruise traveling in still water is equal to 12mph.
So,
Calculating the time traveled upstream, we have:
[tex](x-4mph)*t_{upstream}=48miles[/tex]
[tex](12mph-4mph)*t_{upstream}=48miles[/tex]
[tex](8mph)*t_{upstream}=48miles[/tex]
[tex]t_{upstream}=\frac{48miles}{8mph}=6hours[/tex]
Calculating the time traveled downstream, we have:
[tex](x+4mph)*t_{downstream}=48miles[/tex]
[tex](12mph+4mph)*t_{downstream}=48miles[/tex]
[tex](16mph)*t_{downstream}=48miles[/tex]
[tex]t_{downstream}=\frac{48miles}{16mph}=3hours[/tex]
Now that we know the time traveled upstream and downstream, we need to calculate the total time traveled using the following equation:
[tex]TotalTime=t_{upstream}+t_{downstream}\\\\TotalTime=6hours+3hours=9hours[/tex]
Hence, we have that the total time traveled is equal to 9 hours.

To ensure an excellent bond when brazing, the clearance gap between pipe and fitting must be _______ inches.
Step-by-step Answer:
Gap must be a maximum of 0.005 inches, and uniform all around. Round out with a sizing tool if necessary.
When brazing, the clearance gap between pipe and fitting should be between 0.002 and 0.006 inches.
This clearance gap is important to allow the brazing material to flow via capillary action and to create a strong, sealed joint. The exact clearance can vary depending on the materials and the application, but staying within this range is a good practice.
For brazing larger diameter pipes and fittings, a slightly larger gap may be acceptable, but generally it is best to maintain the smallest gap that will still allow for proper capillary action of the filler metal.

Match each exponential function to the description of its percent rate of change. 22% growth 12% decay 2% decay 20% growth 20% decay 22% decay 2% growth 12% growth. f(x) = 44(0.88)^x, f(x) = 124(1.22)^x, f(x) = 22(0.8)^x, f(x) = 42(1.12)^x
The exponential function is defined as y = a(1+r)^x, where "a" represents the original account and "r" the rate of growth or decay.
Then we have the following:
1) 22% grow
y = a( 1 + 22%/100 )^x = a(1.22)^x
So the solution is: 124(1.22)^x
2) 12% decay
y = a( 1 - 12%/100 )^x = a(0.88)^x
So the solution is: y = f(x) = 44(0.88)^x
3) 20% decay
y = a( 1 - 20%/100 )^x = a(0.8)^x
So the solution is: f(x) = 22(0.8)
4) 12% Groth
y = a( 1 + 12%/100 )^x = a(1.12)^x
So the solution is: f(x) = 42(1.12)^x
Final answer:
Each exponential function is matched to its percent rate of change by the base of the exponent; a base greater than 1 indicates growth, while a base less than 1 indicates decay.
Explanation:
The question involves matching each exponential function to its corresponding percent rate of change, which indicates whether there is exponential growth or decay. The base of the exponent in the function represents the rate of change: a base greater than 1 indicates growth, while a base less than 1 indicates decay. Here's how we match the given functions:
f(x) = 44[tex](0.88)^x[/tex] corresponds to 12% decay because 0.88 represents a decay rate of 12%.
f(x) = 124[tex](1.22)^x[/tex] corresponds to 22% growth because 1.22 represents a growth rate of 22%.
f(x) = 22[tex](0.8)^x[/tex] corresponds to 20% decay because 0.8 represents a decay rate of 20%.
f(x) = 42[tex](1.12)^x[/tex] corresponds to 12% growth because 1.12 represents a growth rate of 12%.
By recognizing the base of the exponential function, we can determine the percentage rate of change and appropriately classify each function as either exponential growth or decay.
The sum of two numbers is 24. The second number is 4 more than the first number. Let a represent the first number and let b represent the second number. What are the two numbers? Use the table to answer the question.8 and 16 10 and 14 11 and 13 15 and 9
Answer:
10 and 14
Step-by-step explanation:
You need only check the answers to see which one satisfies the problem requirements. The differences between the second and first numbers are ...
8, 4, 2, -6
Only one pair has the second number 4 more than the first: 10 and 14.
_____
Since you are given variable definitions, perhaps you're expected to write and solve equations.
a + b = 24 . . . . . the sum of the two numbers is 24
-a +b = 4 . . . . . . the second number is 4 more than the first
Adding these two equations gives ...
(a +b) +(-a +b) = (24) +(4)
2b = 28 . . . . . simplify; next, divide by 2
b = 14 . . . . . . . identifies 10 and 14 as the correct answer
Answer:

The last time Esteban checked his credit score, it was 740, and his only credit event since has been applying for a store credit card. Which of these is most likely to be his credit score now?
According to the information, it can be inferred that the current credit score for Esteban is 730 because he has not used more transactions than eleven of his credit score.
What is the credit score?A credit score is a term that refers to an index that is intended to predict the chances that you will repay a loan on time.
This takes into account different factors related to your economy, so it is likely that the more movement of money you have, your score will be higher.
Based on the foregoing, it can be inferred that Esteban's score dropped because he has not made important transactions in recent months. Additionally, it has no recent transaction history.

a quadradic polynomial has a degree of 2 true or false
Answer: True
Step-by-step explanation:
We know that the quadratics polynomials have this form:
[tex]f(x)=ax^2+bx+c[/tex]
You need to remember that the degree of a polynomial is given by its highest exponent.
You can observe in the quadratic polynomial [tex]f(x)=ax^2+bx+c[/tex] that the highest exponent is "2", which is the exponent of the term [tex]ax^2[/tex]
Therefore, since the highest exponent is "2", you should conclude that the degree of the polynomial is 2.
Then, you can say that a quadradic polynomial has degree 2.
