A right isosceles triangle is a triangle with a right angle (90 degrees) and two sides that are equal in length. This means that the triangle is also a special case of an isosceles triangle where the two equal sides are adjacent to the right angle.

To identify a right isosceles triangle among a group of shapes, you should look for the shape that has a right angle and two sides of equal length. One way to check for the right angle is to look for a corner that forms a square angle (i.e., 90 degrees), and one way to check for the equal sides is to compare the length of each side.

The price of new Tv is 107,990 including VAT .The percentage increase in price of tv is 8% in rate.

The current price of the plasma TV including VAT at 5% is 99,990 naira.

If the government raises VAT to 8%, the new price of the TV including VAT can be calculated as follows:

New price = current price * (1 + new VAT rate)

New price = 99,990 * (1 + 0.08)

New price = 107,992.2

Rounding the new price to the nearest 10 naira gives: 107,990 naira.

The increase in price of the TV can be calculated as follows:

Price increase = new price - current price

Price increase = 107,990 - 99,990

Price increase = 8,000

The percentage increase in price of the TV can be calculated as follows:

Percentage increase = (price increase / current price) * 100%

Percentage increase = (8,000 / 99,990) * 100%

Percentage increase = 8.0%

Therefore, the new price of the TV including VAT at 8% is 107,990 naira, and there is a 8.0% increase in price.

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.

(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.

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.

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.

------------------------------

Given is an isosceles right triangle.

As per property of a such triangle, its hypotenuse is √2 times its leg.

That is:

Answer:

a = 6 ft

Step-by-step explanation:

We have to find,

→ The value of a in the diagram.

Formula we use,

=> Using Pythagoras theorem.

→ (Hyp)² = (Opp)² + (Base)²

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.

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).

The probability that at least one pair of people have the same birthday, with 30 people in a classroom is approximately 0.7063.

To solve this problem, we can use the concept of the complement of an event. The complement of the event "at least one pair of people have the same birthday" is the event "no pair of people have the same birthday." So, we can find the probability of this complement event and subtract it from 1 to get the probability of the original event.

The probability that the first person has a unique birthday is 1, since there are no other people in the room yet. The probability that the second person also has a unique birthday is (364/365), since there are 364 remaining days in the year that they could be born on.

Similarly, the probability that the third person has a unique birthday is (363/365), and so on, down to the 30th person, whose probability of having a unique birthday is (336/365).

To find the probability that no pair of people have the same birthday, we can multiply these probabilities together:

P(no pair share a birthday) = 1 * (364/365) * (363/365) * ... * (336/365) ≈ 0.2937

Therefore, the probability that at least one pair of people have the same birthday is:

P(at least one pair share a birthday) = 1 - P(no pair share a birthday) ≈ 1 - 0.2937 = 0.7063

So the probability that at least one pair of people have the same birthday is approximately 0.7063, which is quite high. This is known as the birthday problem or birthday paradox.

The length of Mr. Neil's homeroom is (10/11) times the length of Miss Robert'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.
