Forming the equation,
→ (6√2)² = (a)² + (a)²
Now the value of a will be,
→ (6√2)² = (a)² + (a)²
→ (a)² + (a)² = (6√2)²
→ 2a² = 36 × 2
→ 2a² = 72
→ a² = 72 ÷ 2
→ a² = 36
→ a = √(36)
→ [ a = 6 ft ]
Hence, the value of a is 6 ft.

Find the following probability, given the number of trials and the probability of obtaining a success. Round your answer to four decimal places. P(X≥8) , n=9 , p=0. 8
The probability of getting 8 or more successes in 9 trials, with given success rate in each trial is 0.8, is 0.9520.
To find the probability , we can use the cumulative distribution function (CDF) of the binomial distribution:
P(X ≥ 8) = 1 - P(X < 8) = 1 - P(X ≤ 7)
Using a binomial calculator or a binomial probability distribution table, we can find:
P(X ≤ 7) = 0.0480 (rounded to four decimal places)
Therefore,
P(X ≥ 8) = 1 - 0.0480 = 0.9520
So the probability of getting 8 or more successes in 9 trials, given the probability of success in each trial is 0.8, is 0.9520 (rounded to four decimal places).

How does the graph of g(x) = (x - 2)3 + 7 compare to the parent function f(x) = x³?
The graph of g(x) = (x - 2)^3 + 7 is a transformation of the parent function f(x) = x^3.
The parent function f(x) = x^3 has a shape that is symmetrical about the origin and increases as x moves away from the origin. The graph of g(x) = (x - 2)^3 + 7 is also symmetrical about the origin, but it has been translated 2 units to the right and 7 units up from the parent function.
So, the graph of g(x) = (x - 2)^3 + 7 is similar in shape to the parent function f(x) = x^3, but it is shifted to the right and up on the coordinate plane.

Gavin wraps a gift box in the shape of a triangular prism. The figure below shows a net for the gift box. How much wrapping paper did he use, in square meters?
The amount of wrapping paper used by Gavin to wrap a triangular prism box is 647.75 m².
What is a prism?
A prism is a polyhedron in geometry made up of an n-sided polygon basis, a second base that is a rigidly translated copy of the first base, and n additional faces that must all be parallelograms and connect the corresponding sides of the two bases.
The formula for area of rectangle is -
Area = length × breadth
The area of rectangle ABFG is -
Area = AB × BF
The value for line segment AB = 15 m
The value for line segment BF is -
BF = BC + CE + EF
BF = 14 + 7 + 15.65
BF = 36.65 m
So, the area of rectangle ABFG is -
Area = 15 × 36.65
Area = 549.75 m²
Now, the triangular prism has triangle part left.
The formula for area of triangle is -
Area = 1/2 × base × height
So, the area of triangle IJH is -
Area = 1/2 × IJ × JH
The value for line segment IJ = 14 m
The value for line segment JH = 7 m
So, the area of triangle IJH is -
Area = 1/2 × 14 × 7
Area = 49 m²
Since, there are two triangles (Δ IJH = Δ CDE ) so the area of total shape is -
Total area = Area of ABFG + 2(Area of Δ IJH)
Total area = 549.75 + 2(49)
Total area = 647.75 m²
Therefore, the area of triangular prism box is 647.75 m².

Jack works at a party supply store. He sold 750 balloons in the last 15 days. What was his selling rate in balloons per day
his selling rate is: 750 balloons / 15 days = 50 balloons per day . To calculate Jack's selling rate in balloons per day, we need to divide the total number of balloons he sold by the number of days he worked.
This means that Jack sold an average of 50 balloons per day over the last 15 days. This information is useful for several reasons. For example, the party supply store might use this information to evaluate Jack's performance and determine whether he is meeting their expectations. It might also be useful for forecasting future sales, since if Jack continues to sell balloons at a rate of 50 per day, we can estimate how many balloons he will sell in a future period of time by multiplying the number of days by 50. In this case,
Jack sold 750 balloons in 15 days, so his selling rate is: 750 balloons / 15 days = 50 balloons per day
It's important to note that the selling rate of 50 balloons per day is an average, and it's possible that Jack's sales varied from day to day. For example, he might have sold more balloons on some days and fewer on others. However, by calculating the average selling rate, we get a general sense of how many balloons Jack sold per day over the course of the last 15 days.
In conclusion, Jack's selling rate in balloons per day over the last 15 days was 50 balloons. This information provides insight into Jack's performance and can be used to make informed decisions about future sales.

At what rate is the amount of water in the tank changing? Use a signed number (positive or
negative) in your answer.
How many more minutes will it take for the tank to drain completely?
How many minutes before Kiran arrived was the water tank completely full?
(a) The rate at which the amount of water is changing is -1/2.
(b) It will take 20 more minutes to drain the water completely.
(c) The tank was completely full 3 minutes before Kiran arrive.
What is Unit Rate?Unit rate is the amount of one quantity for a unit amount of the other quantity.
(a) Given that,
When Kiran first sees the tank, it contains 12 gallons of water. Four minutes later, the tank contains 10 gallons of water.
Rate at which the amount of water is changing = (10 - 12) / 4 = -2/4 = -1/2 gallons per minute.
(b) Time taken to drain 1/2 gallon = 1 minute
There are 10 gallons of water remaining in the tank.
Time taken to drain 10 gallons of water = (1 ÷ 1/2) × 10 = 20 minutes
It will take 20 more minutes to drain the water completely.
(c) When Kiran arrived, water tank has 12 gallons of water.
Total amount of water in the tank is 15 gallons.
Tank has lost 3 gallons of water before Kiran arrived.
Time taken to drain 3 gallons = (1 ÷ 1/2) × 3 = 6 minutes
So the tank was completely full 3 minutes before Kiran arrive.

Homeroom
The length of Mr. Neil's homeroom is (10/11) times the length of Miss Robert's homeroom.
What is the length of Mr. Neil's homeroom?The length of Mr. Neil's homeroom is calculated as follows:
Let's assume that Miss Robert's homeroom has width w and length l, and Mr. Neil's homeroom has width (1¹/₁₀ or 11/10)w and length x.
Both homerooms have the same perimeter, therefore:
2w + 2l = 2(11/10)w + 2x
Simplifying the equation:
2l - 2x = (2/10)w
l - x = (1/10)w
x = l - (1/10)w
To solve for x, we need to express it in terms of l and w.
From the equation above, we can substitute x with l - (1/10)w:
(11/10)w = 2l - x
(11/10)w = 2l - l + (1/10)w
(10/10)w = l + (1/10)w
w = (10/11)l
Substituting w with (10/11)l in the expression for x, we get:
x = l - (1/10)(10/11)l
x = l - (1/11)l
x = (10/11)l
Therefore, the length of Mr. Neil's homeroom is (10/11) times the length of Miss Robert's homeroom.

Anna ate 5 8 of an orange and gave the other 3 8 to her brother. Which equation can be used to find the difference between the amount Anna ate and the amount she gave her brother?
The difference between the amount Anna ate and the amount she gave to her brother can be found by subtracting 3/8 from 5/8. This can be expressed as an equation by writing 5/8 - 3/8 = x, where x is the difference.
5/8 - 3/8 = x
5/8 = 5 ÷ 8
= 0.625
3/8 = 3 ÷ 8
= 0.375
0.625 - 0.375 = x
= 0.25
Therefore, the difference between the amount Anna ate and the amount she gave to her brother is 0.25.The difference between the amount Anna ate and the amount she gave to her brother can be found by subtracting 3/8 from 5/8. This can be expressed as an equation by writing 5/8 - 3/8 = x, where x is the difference. To solve this equation, we first need to convert the fractions into decimal values. 5/8 is equal to 5 divided by 8, which is equal to 0.625. 3/8 is equal to 3 divided by 8, which is equal to 0.375. We can then subtract 0.375 from 0.625 to get the difference. This gives us 0.25, which is the difference between the amount Anna ate and the amount she gave to her brother. Therefore, the answer to the equation 5/8 - 3/8 = x is x = 0.25.

For any value of x, g(x) will always be greater than h(x).
For any value of x, h(x) will always be greater than g(x).
g(x) > h(x) for x = -1.
g(x) < h(x) for x = 3.
For positive values of x, g(x) > h(x).
For negative values of x, g(x) > h(x).
The statement that is true about the quadratic functions is:
g(x) > h(x) for x = -1.
Which statements are true for functions g(x) and g(x)?Here we have the two quadratic functions:
g(x) = x^2
h(x) = -x^2
Notice that h(x) = -g(x).
Also, g(x) is always positive or zero, while h(x) is always negative, but for x = 0 both have the same value.
g(0) = 0^2 = -0^2 = h(0)
Then the statement that is true is
g(x) > h(x) for x = -1.

What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
