Step-by-step explanation:
13y-8>18
+8 +8
13y>26
/13 /13
y>2
Step 1: Add 8 to both sides of the equation (-8+8, cancels) (18+8=26)
Step 2: Divide 13y and the result of step 1 (26) by 13
Step 3: Find answer (y>2)
I hope this helps
Answer: y > 2
Let's solve your inequality step-by-step.
13y−8>18
Step 1: Add 8 to both sides.
13y−8+8>18+8 (Addition of 8 undoes the subtraction of 8)
13y>26
Step 2: Divide both sides by 13.
13y/13 > 26/13 (Division of 13 undoes the multiplication of 13 * y)
y > 2

Answer:
9 5/6
Step-by-step explanation:
Add the whole numbers and the fractions separately
(5 + 4) + (1/2 + 1/3)
Add
9 + 5/6
Write as a mixed number
9 5/6
Answer:
9 and 5/6
Step-by-step explanation:
We can start by adding 5 + 4 which equals 9
Then we add 1/2 to 1/3
Both these numbers can be changed to one with the same denominator
So, 1/2 = 3/6 and 1/3 = 2/6
= 3/6 + 2/6
= 5/6
Add 5/6 back to the 9 we got earlier, we get 9 5/6
Amanda’s family is taking a road trip. Their car can travel no more than 352 miles without needing to refill the gas tank. They have traveled 108 miles since they last filled the gas tank. Amanda knows that the inequality representing this situation is 108 + x< 352. Select from drop-down menu to correctly interpret the solution of this inequality.
The correct interpretation of the inequality 108 + x < 352 is given as follows:
Amanda's family has already traveled 108 miles, and needs to fill the tank after traveling more 244 miles.
What is the meaning of the inequality?
The inequality for this problem is defined as follows:
108 + x < 352.
The variable x represents the number of miles that the car can still travel until needing to refill the gas tank.
The solution is obtained similarly to an equality, isolating the variable x and obtaining a range of values, as follows:
x < 352 - 108
x < 244.
(the difference is that the solution of the inequality obtains a range of a values, while for the equality it is a single value).
Hence the family can travel at most 244 miles until needing to refill the tank again to continue the trip.

Lincoln is driving on a long road trip. He currently has 9 gallons of gas in his car. Each hour that he drives, his car uses up 1.25 gallons of gas. How much gas would be in the tank after driving for 2 hours? How much gas would be left after tt hours?
Answer:
The car will use up 1.25 gallons of gas per hour of driving, so after 2 hours of driving, the car will have used 2 * 1.25 = 2.5 gallons of gas.
If Lincoln started the trip with 9 gallons of gas in the car, after 2 hours of driving, he will have 9 - 2.5 = 6.5 gallons of gas left in the tank.
We can generalize this to any number of hours by using the formula:
Gas left = 9 - (1.25 * number of hours driven)
So if he drives for t hours, the amount of gas he will have left in the tank is:
Gas left = 9 - (1.25 * t)

What is Pythagoras theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic Euclidean geometry relationship between a right triangle's three sides. According to this rule, the area of the square with the hypotenuse side is equal to the sum of the areas of the squares with the other two sides. The Pythagorean Theorem states that the squares on the hypotenuse of a right triangle, which is the side that faces the right angle, are equal when added together. This is written as a2 + b2 = c2 in the usual algebraic notation.The measure of angle A is 90°. It means triangle ABC is a right angle triangle.

Find the area of the triangle below.
Be sure to include the correct unit in your answer.
The area of the triangle is 38 cm^2.
Find the area of the triangle below?To find the area of the triangle given, we need to know the length of the third side.The third side, ac, can be found using the Pythagorean theorem.The Pythagorean theorem states that the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.In this case, the hypotenuse is ac, so we can create the equation a^2+b^2=c^2, where a and b are the lengths of the two sides of the triangle.Since a is 18 cm and b is 13 cm, we can solve the equation to get c^2=18^2+13^2=361. Therefore, ac=√361=19 cm.Now that we have the length of the third side, ac, we can use the formula for the area of a triangle, Area=1/2(base)(height).In this case, the base of the triangle is 19 cm and the height is 4 cm. Therefore, the area is 1/2(19)(4)=38 cm^2. Therefore, the area of the triangle is 38 cm^2.ac=√(18^2+13^2)=21.93 cmarea=1/2(ab)(height)=1/2(18)(4)=36 cm^2.To learn more about The formula for the area of a triangle refer to:

How far apart are the two cities located?Remember that if we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points can be calculated as:
distance = √( (x₁ - x₂)^2 + (y₁ - y₂)^2)
In this case we want to find the distance between (−25,−84) and (−73,−84), we will get:
distance = √( (-25 + 73)^2 + (-84 + 84)^2)

Question 1 Part A: (4 Points): A researcher is following the growth of a particular type of flower. She writes the given equation to show the height of the flower g(n), in inches, and n days.
Complete the inequality below by dragging and dropping the answers on the left into the given boxes
Answer:
0 ≤ n ≤ 5
Step-by-step explanation:
We have the function for growth as
[tex]g(n) = 10(1.02)^n[/tex]
We also know that after a specific n days, the flower has grown to 11.04 inches
Since g(n) represents the height of the flower, we can substitute 11.04 for g(n) and solve for n
∴We get
[tex]11.04 = 10(1.02)^n[/tex]
Switching sides we get
[tex]10(1.02)^n = 11.04[/tex]
Divide both sides by 10 to get
[tex]1.02^n = 1.104[/tex]
Take log on both sides
[tex]\log(1.02^n) = \log(1.104)[/tex]
[tex]\log(x^a) = a \log(x)[/tex]
So
[tex]\log(1.02^n) = n \log(1.02)[/tex]
Therefore
[tex]n \log(1.02) = \log(1.104)[/tex]
[tex]n = \dfrac{\log(1.104)}{\log(1.02)}[/tex]
Using a calculator this works out to
[tex]n = 4.9963[/tex]
Therefore it takes at least these many days for the flower to reach 11.04 inches
Rounding number of days to 5, we get the right side of the inequality as n ≤ 5
n cannot be negative so it starts of with a value of 0 so on the right side of the inequality we get n ≥ 0 which can be rewritten as 0 ≤ n
Together the domain of n can be represented as
0 ≤ n ≤ 5

A sample of 100 items is taken from a process that has been adjusted after it was found that its mean had shifted. The sample mean is 65. The sample standard deviation is 10. Which of the following is a 90 percent confidence interval.
62 to 68
59 to 69
63 to 67
65 to 67
A 90 percent confidence interval estimate for the mean of the sample is 63 to 67.
Confidence interval is defined as the range of values where a parameter might fall at a given confidence level. It can be calculated using the formula below.
CI = μ ± z x (SD / √n)
where CI = confidence interval
μ = sample mean
z = found by using a z-score table
SD = sample standard deviation
n = sample size
At 90% confidence interval, the area in each tail of the standard normal curve is 5, and the cumulative area up to the second tail is 95.
(100 - 90) / 2 = 5
100 - 5 = 95
Find 0.95 in the z-table to get the value of z.
At p = 0.95, z = 1.647
Plug in the values and solve for the confidence interval.
CI = μ ± z x (SD / √n)
CI = 65 ± 1.96 x (10 / √100)
CI = 65 ± 1.96
CI = [63.04, 66.96]
CI ≅ 63 to 67

nswer: The perimeter is approximately equal to 43.7 ft.
Step-by-step explanation:
since we are working with a square, we know all the sides tend to have equal measurements including the side which acts as a hypotenuse to the triangle. Therefore, if we somehow find the measurement of the hypotenuse we'll be able to get the measurement of all sides of the square which we could add in to the two other sides of the triangle to get the perimeter.
Joshua calculated the hypotenuse wrong. The correct calculation is:
hypotenuse² = 7² + 7²
hypotenuse = √( 7² + 7²)
hypotenuse = √( 49 + 49)
hypotenuse = √( 98)
hypotenuse = 7√2
now it's going to be easy doing further calculation. We will three sides of square add them to two other sides of the triangle and get the perimeter.
