The given triangle is a right angled triangle, therefore the rules of basic Trigonometry can be used here to find the solution.

\(\qquad\displaystyle \tt \dashrightarrow \: \sin(45 \degree) = \frac{opposite \:\: side}{hypotenuse} \)

[ sin 45° = 1/√2 ]

\(\qquad\displaystyle \tt \dashrightarrow \: \frac{1}{ \sqrt{2} } = \frac{b}{x} \)

\(\qquad\displaystyle \tt \dashrightarrow \: x = b \sqrt{2} \: \: cm\)

So, the side HG is b√2 cm long

Answer:

3/4

Step-by-step explanation:

3/4+x=2x−x+_

2x-x is x

So the equation is now

3/4+x=x+_

So to have infinite solutions, we will have to get both of the sides the same value

Since there is already an x on both sides we don't have to worry about it

Now there isn't a 3/4 on one side so we can just add that to the blank side, thus creating an infinite solution equation

Hope this helps!

Answer:

11.3 ft high

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

4² + b² = 12²

16 + b² = 144

b² = √128

b = 11.3

The water cooler tank has to be filled 18 times to quench the thirst of 1200 students.

We have

Number of students= 1200

Water consumption per student= 750 ml

So, Total water consumption

= Number of students × Water consumption per student

= 1200 × 750 ml

= 900000 ml

= 900 Liter

Now, the time cooler tank has to be filled to quench the thirst

= 900 / 50

= 18 times

Thus, the water cooler tank has to be filled 18 times to quench the thirst of 1200 students.

Answer:

slope is 2/3

Step-by-step explanation:

12=4x-6y

We add 6y both sides

12+6y=4x

than subtract 12 from both sides

6y=4x-12

than divide both sides by 6

y=2/3x-2

and the slope is  2/3

If the first digit of a six-digit number is 1.  the last three digits of the original number is: (0, 2, 4, 6, or 8) for the equation to hold.

Let's represent the original six-digit number as ABCDEF, where A is the first digit, and F is the last digit. Since we know that A is 1, we can represent the original number as 1BCDEF.

When we move the digit 1 from the first digit position to the end, we get the new number BCDE1F. We are told that this new number is three times larger than the original number, so:

BCDE1F = 3 × 1BCDEF

BCDE1F = 300000B + 30000C + 3000D + 300E + 30F

Simplifying this equation, we get:

100000B + 10000C + 1000D + 100E + 10F + 1 = 3(100000 + 10000B + 1000C + 100D + 10E + F)

Expanding the right-hand side, we get:

100000B + 10000C + 1000D + 100E + 10F + 1 = 300000 + 30000B + 3000C + 300D + 30E + 3F

Simplifying further, we get:

70000B + 7000C + 700D + 70E + 7F = 299999

Dividing both sides by 7, we get:

10000B + 1000C + 100D + 10E + F = 42857

Since we know that F is the digit 1, we can rewrite this equation as:

10000B + 1000C + 100D + 10E + 1 = 42857

Subtracting 1 from both sides, we get:

10000B + 1000C + 100D + 10E = 42856

The last three digits of the original number are BCE. To find them, we can divide both sides of the above equation by 100 and take the remainder:

(10000B + 1000C + 100D + 10E) mod 100 = 56

Simplifying the left-hand side, we get:

(100B mod 100) + (10C mod 100) + (D mod 100) + (10E mod 100) = 56

Since the first three terms are divisible by 100, we can ignore them and focus on the last term:

10E mod 100 = 56

The only digit of E that satisfies this equation is 6. Therefore, the last three digits of the original number are 1BC, which is 16C in decimal form. We don't have enough information to determine the exact value of C, but we know that it must satisfy the equation:

10000B + 1000C + 100D + 10(6) = 42856

Simplifying, we get:

1000C + 100D = 42796 - 10000B

Since the left-hand side is divisible by 100, the right-hand side must also be divisible by 100. Therefore, B must be an even digit (0, 2, 4, 6, or 8) for the equation to hold.

The steps peter could use in solving the quadratic equation is by applying the quadratic formula; x = –1 Plus or minus StartRoot StartFraction 5 Over 8 EndFraction EndRoot

8x² + 16x + 3 = 0

using Quadratic formula

The following steps are involved

\(x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{ 2a }\)

\(x = \frac{ -16 \pm \sqrt{16^2 - 4(8)(3)}}{ 2(8) }\)

\(x = \frac{ -16 \pm \sqrt{256 - 96}}{ 16 }\)

\(x = \frac{ -16 \pm \sqrt{160}}{ 16 }\)

\(x = \frac{ -16 \pm 4\sqrt{10}\, }{ 16 }\)

\(x = \frac{ -16 }{ 16 } \pm \frac{4\sqrt{10}\, }{ 16 }\)

\(x = -1 \pm \frac{ \sqrt{10}\, }{ 4 }\)

\(x = -1 \pm \frac{ \sqrt{5}\, }{ 2 }\)

\(x = -0.209431\)

Answer:

Step-by-step explanation:

Answer:

(a.) Area = 6.00 square units

(b.) Area = 15.59 square units

Step-by-step explanation:

(a.) The regular formula for the area of a triangle is A = 1/2bh, where

In this triangle, the height is 3 units and the base is 4 units.  Thus, we plug in 3 for h and 4 for b in the formula to find A, the area in square units:

A = 1/2(4)(3)

A = 2 * 3

A = 6

Thus, the area of the triangle is 6.00 square units.

(b.)

a^2 + b^2 = c^2, where

Thus, we can plug in 3 for a and 6 for c, allowing us to solve for b, the height of the entire triangle:

3^2 + b^2 = 6^2

9 + b^2 = 36

b^2 = 27

√(b^2) = √(27)

b = √(9 * 3)

b = 3√3 (leaving the answer in the simplest radical form will allow us to get a more exact answer when finding the area of the triangle.

Thus, the height of the triangle is 3√3 units.

Area of the triangle in (b.):

Now, we can plug in 6 for b and 3√3 for h in the triangle area formula to find A, the area of the triangle in square units:

A = 1/2(6)(3√3)

A = 3(3√3)

A = 9√3

A= 15.58845727

A = 15.59

Thus, the area of the triangle is about 15.59 square units.

I attached a picture that shows how the triangle in (b.) can be divided into two triangles.

6 tables are required. Each prime number attender should serve 3 customers each.

The prime numbers between 1 and 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

All the numbers other than prime numbers are composite numbers.

The composite numbers from 1 to 100 are: 1, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.

Now, as there are 25 primes and 75 composites in the group that visited the restaurant, we can calculate the number of tables required by dividing the number of people by the seating capacity of each table.

Each table has a seating capacity of 15, so the number of tables required will be: Number of tables = (Number of customers)/(Seating capacity of each table)Number of customers = 25 (the number of primes) + 75 (the number of composites) = 100Number of tables = 100/15 = 6 tables

Therefore, 6 tables are required.

Now, as each prime number attender has to serve an equal number of customers, we need to calculate how many customers each one should serve.

Each prime attender has to serve 75/25 = 3 customers each, as there are 75 composites and 25 primes.

Thus, each prime number attender should serve 3 customers each.
