Answer:

273ft²

Step-by-step explanation:

Fabric needed

= 2([tex]\frac{1}{2}[/tex]×7×6) + 3(7×11)

= 42ft² + 231ft²

= 273ft²

Answer:

1/12

Step-by-step explanation:

1/12

Step-by-step explanation:

3/4 + z = 5/6

Subtract 3/4 from each side

3/4 -3/4+ z = 5/6-3/4

z = 5/6 -3/4

Get a common denominator of 12

z = 5/6 *2/2 -3/4 *3/3

z = 10/12 - 9/12

z = 1/12

Answer:

Step-by-step explanation:

The Pythagorean theorem applies to right angled triangles only.

However, for any other triangle, by dropping a perpendicular from any vertex on to the opposite side, you form two right angled triangles both of which can be solved by the Pythagorean theorem.

So, the Pythagorean theorem applies to right angled triangles directly and to other triangles indirectly.

9514 1404 393

Answer:

  right triangles

Step-by-step explanation:

The Pythagorean theorem relates the side lengths of a right triangle.

  c² = a² +b² . . . . . . . . for legs 'a' and 'b' and hypotenuse 'c'

__

Additional comments

The more general form of the relation between side lengths of a triangle is given by the Law of Cosines:

  c² = a² +b² -2ab·cos(C) . . . . for sides 'a', 'b', and 'c' with angle C opposite side 'c'

You will notice this reduces to the Pythagorean relation when C = 90°.

__

Triples of integers that satisfy the Pythagorean relation are called Pythagorean triples. The smallest set (and the only sequential set) of these is (a, b, c) = (3, 4, 5). Other triples commonly seen in math problems are (5, 12, 13), (7, 24, 25), (8, 15, 17), and multiples of these.

Answer:

12 girls

36 boys

Step-by-step explanation:

Answer:12 girls

Step-by-step explanation:

3 Shares boys (Due to it being 3 times more) 1 Share girls

3 Shares boys + 1 Share girls= 4 Shares

48 / 4 Shares = 12

Girls are 1/4 of the 48

so there are 12 girls

Answer:

$300

Step-by-step explanation:

Front row: $225

Front row = 3 * balcony

225 = 3 * balcony

balcony = $225/3 = $75

One balcony ticket costs $75.

4 balcony seats = 4 * $75 = $300

Answer: $300

Answer:

2x9 + 2x3

Step-by-step explanation:

You distribute the 2 to the other terms (9 and 3) in the brackets.

Answer:

y = 4/7 - 4

Step-by-step explanation:

Slope = (-4-0) / (0 - 7) = -4/-7 = 4/7

y-intercept: -4 - (4/7)(0) = -4

Answer:

471.24

Step-by-step explanation:

Answer:

A= 471.24

Step-by-step explanation:

The formula for the surface area of a cylinder is

[tex]A=2\pi rh+2\pi r^2[/tex]

What we know is

Using these numbers, we can know plug them into the formula.

[tex]A=2\pi (5)(10)+2\pi(5)^2[/tex]

Simplify

[tex]A= 100\pi + 50\pi[/tex]

[tex]A= 150\pi[/tex]

[tex]A= 471.24[/tex]

Answer:

x=1, y=10

Step-by-step explanation:

we use substitution to get from the bottom equation that y=12-2x,

plug that into the first equation to get 5x+12-2x=15

combining like terms and cancelling, we get 3x=3

so x=1,

substituting that into the former equation gives us y=10

Answer:

Step-by-step explanation:

ax² + bx + c = y

x² + 5x – 21 = 0

First make sure the (a) term = 1... It is.

Get (c) to zero or blank by adding or subtracting as needed.

x² + 5x – 21 + 21 = 0 + 21

x² + 5x       = 21

Add the square of half of the b term to each side

x² + 5x + (5/2)² = 21 + (5/2)²

x² + 5x + (5/2)² = 27.25

rewrite the left side as a square

(x + 2.5)² = 27.25

square root of each side

x + 2.5 = ±√27.25

isolate x

x = -2.5 ±√(27.25)

x ≈ 2.72 or -7.72

Answer:

[tex]\frac{25}{4}[/tex] = 6.25

Step-by-step explanation:

x² + 5x - 21 = 0 ( add 21 to both sides )

x² + 5x = 21

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2([tex]\frac{5}{2}[/tex] )x + [tex]\frac{25}{4}[/tex] = 21 + [tex]\frac{25}{4}[/tex]

(x + [tex]\frac{5}{2}[/tex] )² = [tex]\frac{109}{4}[/tex]

Answer:

a+b+x=180,sum of angles in a triangle

54+48+x=180

102+x=180

x=180-102

x=78

Answer:

All you have to do is add 11 four times and then add 18 four times. Then once you have added them up, you add those two numbers and that is how you get your answer.

Step-by-step explanation:

11+11+11+11= 44

18+18+18+18=72

44+72=116

116 is the answer

Not function because its a vertical line.

Answer:

1

Step-by-step explanation:

I think C(12,0) means 12 choose 0. If yes, then the answer is 1. There is only 1 way to pick 0. Or, you can calculate it with the form:

C(12,0) = [tex]\frac{12!}{0!(12-0)!}[/tex] ⇒

[tex]\frac{12!}{1*12!}[/tex] = 1
