Answer:

y^2-1=80

y^2=81

y = positive and negative 9

y2−1=80

Step 1: Add 1 to both sides.

y2−1+1=80+1

y2=81

Step 2: Take square root.

y=±√81

y=9 or y=−9

Answer:

y=9 or y=−9

Step-by-step explanation:

Answer:

red) area = 59.2 km²

Step-by-step explanation:

area of bottom 4 x 4 = 16

area of 4 sides = 4 (1/2)(4)(5.4) = 43.2

16 + 432 = 59.2 km²

Answer:

Step-by-step explanation:

lateral area = 2(base)(slant height) = 2·4·2 = 16 km²

base area = base² = 4² = 16 km²

surface area = 16 + 16 = 32 km²

Answer:

15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.

Step-by-step explanation:

Dado que en una encuesta a 200 niños sobre el programa de TV que más les gusta ver se encontró que 30 niños ven dibujos animados, 45 niños miran películas animadas, 55 niños miran programas sobre animales, 38 niños miran programas sobre animales y dibujos animados y 32 niños miran los tres tipos de programas, para determinar el porcentaje de cada grupo​ se deben realizar los siguientes cálculos:

30/200 = 15/100 = 15%

45/200 = 22.5/100 = 22.5%

55/200 = 27.5/100 = 27.5%

38/200 = 19/100 = 19%

32/200 = 16/100 = 16%

Así, 15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.

Do 62 divided by 8

Answer:

Step-by-step explanation:

1) B=8cm                          H=5.5

A=1/2xbxh

A=I/2 x 8 x 5.5

A=22

The area of the first traingle is 22cm

2)

B=12cm                                 h=8.4

A=1/2xbxh

A=1/2 x 12 x 8.4

A=50.4

Answer:

m = 90/80 = 9/8

Step-by-step explanation:

If you meant the line through the origin (0, 0) and (80, 90), then the change in x is 80 and that in y is 90.  The slope is m = (change in y) / (change in x), or

m = 90/80 = 9/8

Answer:

(-5,2)

Step-by-step explanation:

To find the solution to the system of equations, just find where the lines intersect. Since they intersect at (-5,2), the solution is (-5,2)

Answer: D.) 2

Step-by-step explanation:

In a rhombus, all sides are congruent; they have the same lengths (like a square). This means that if this parallelogram was a rhombus, 14 - x and 2x + 8 will have to be equal.

14 - x = 2x + 8

Subtract 2x from both sides

14 - 3x = 8

Subtract 14 from both sides

-3x = -6

Divide both sides by -3

x = 2

Answer:

It is the right-angled triangle.

Step-by-step explanation:

According to the Pythagorean theorem, [tex]a^{2}+b^{2}=c^{2}[/tex], which c is the longest side of the triangle.

So, [tex]27^{2}+36^{2}=45^{2}[/tex] if the triangle is right angle.

[tex]LHS=27^{2} + 36^{2} = 2025[/tex]

[tex]RHS=45^{2}=[/tex][tex]RHS=45^{2} = 2025[/tex]

∵LHS=RHS

∴It is a right-angled triangle.

Answer:

The right angled triangle

Answer:

Step-by-step explanation:

WASSUP

Answer:

16.5 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the other leg, then

x² + 13² = 21²

x² + 169 = 441 ( subtract 169 from both sides )

x² = 272 ( take the square root of both sides )

x = [tex]\sqrt{272}[/tex] ≈ 16.5 cm ( to the nearest tenth )

Answer:

2.7

Step-by-step explanation:

Let the number alex think be x

Answer = 22.7

According to the question,

x + 20 = 22.7

x = 22.7 - 20

x = 2.7

Therefore, his original number is 2.7

Answer:

NM = 13

Step-by-step explanation:

pythagorean theorem: [tex]a^{2} + b^{2} = c^{2}[/tex]

a or NO = 5

b or OM = 12

c or NM = ?

plug in what is known:

⇒ [tex]5^{2} + 12^{2} = c^{2}[/tex]

⇒ [tex]25 + 144 = c^{2}[/tex]

⇒ 169 = [tex]c^{2}[/tex]

square root each side of the equation:

⇒ [tex]\sqrt{169} = \sqrt{c^{2} }[/tex]

solve:

⇒ 13 = c
