Answer:

  9/16

Step-by-step explanation:

We presume an error in the problem statement. A yard is a measure of distance, not weight.

A pound contains 16 ounces. Then 9 ounces is 9/16 of a pound.

__

As a decimal fraction, that is 0.5625 lb.

Step-by-step explanation:

Sorry if it's wrong.

Answer:

a) because of the distributive property when you distribute you get 2x+8=2x+8

b) because when you distribute, you get 3x+7=3x+21 which is not equal so no value of x will work

Answer:

a) 2x + 8 = 2(x + 4) has infinite solutions because it simplifies down to x = x. Here is the work where this equation is solved.

2x + 8 = 2(x + 4)

2x + 8 = 2(x) + 2(4)

2x + 8 = 2x +8

2x + 8 - 8 = 2x + 8 -8

2x = 2x

2x/2 = 2x/2

x = x

So, because the equation ends in x = x, you can substitute any value for x and the equation will remain true.

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

b) 3x + 7 = 3(x + 7) has no solutions because it simplifies down to an untrue statement. The equation is simplified below.

3x + 7 = 3(x + 7)

3x + 7 = 3(x) + 3(7)

3x + 7 = 3x + 21

3x + 7 - 7 = 3x + 21 - 7

3x = 3x + 14

3x/3 = 3x/3 +14

x = x + 14

However, this is false. x cannot be equal to itself plus 14.

x ≠ x + 14

The simplification of this equation is untrue, so there is no solution to it.

Answer: 24

Step-by-step explanation:

Given

[tex]2x^4+2y^4+2z^4=144[/tex]

dividing whole equation by 2, we get

[tex]\Rightarrow x^4+y^4+z^4=72[/tex]

Mean is given by the sum of the value of entities divided by the total no of entities

[tex]\Rightarrow \text{Mean}=\dfrac{x^4+y^4+z^4}{3}\\\\\Rightarrow \text{Mean}=\dfrac{72}{3}\\\\\Rightarrow \text{Mean}=24[/tex]

Answer:

  42.3

Step-by-step explanation:

The appropriate trig ratio is ...

  Tan = Opposite/Adjacent

  tan(78°) = x/9

  x = 9×tan(78°)

  x ≈ 42.3

Answer:

37  smallest number

Step-by-step explanation:

If your integer is x

The next 5 odd integers are:

x+2

x+4

x+6

x+8

x+10

x+x+2+x+4+x+6+x+8+x+10=252

6x+30=252

6x=252-30

6x=222

x=222/6

x=37

Total surface area of cone is 176π

Surface area of curved surface of a cone is give by π⋅r.l , where r is the radius and l is the slant height of the cone.

Hence surface area of curved surface of a cone is π×8×14=112π .

As surface area of base is π×82=64π .

Hence total surface area is 112π+64π=176π

The surface area of the given cone is 552.64 units²

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

Given that, a cone has a radius of 8 and slant height of 14 units, we need to find its surface area,

The surface area of cone = π ·r²+ π·r·l, where l is the slant height,

So,

SA = (3.14 × 8²) + (3.14 × 8 × 14)

= 200.96 + 351.68

= 552.64

Hence, the surface area of the given cone is 552.64 units²

Answer:

(x–1)(x²–6x+6)

Explanation:

Given that 1 is a zero, we can use synthetic division to compute the factor.

If 1 is a zero (x–1) is a factor.

Here is the process:

| 1 | 1 -7 12 -6

↓ +(1) +(-6) +(6)

↓ ↓ ↓

1 -6 6 0

→ [1]x² + [-6]x + [6]1 + [0]/x–1 =

x² – 6x + 6.

Therefore the factors are (x–1)(x²–6x+6)

57°

Step-by-step explanation:

180-56=114

114÷2=57

Answer:

57°

Step-by-step explanation:

AO and BO are both the radius of the circle, so they are equal.  Since it makes an iscosoles triangle, angles A and B are equal.

180-66=114

114/2=57

Answer:

C. [tex] a \leqslant 4[/tex]

Step-by-step explanation:

[tex]a \leqslant 4[/tex]

Option C is the correct answer.

Answer:

Step-by-step explanation:

Quadratic equation has been given as,

[tex]y=-x^{2} +6x+4[/tex]

Converting this equation into vertex form,

[tex]y=-(x^{2}-6x)+4[/tex]

[tex]y=-[x^{2}-2(3x)+9-9]+4[/tex]

[tex]y=-[x^{2}-2(3x)+3^2]+4+3^2[/tex]

[tex]y=-(x-3)^2+4+9[/tex]

[tex]y=-(x-3)^2+13[/tex]

By comparing this equation with the vertex form of a quadratic equation,

y = (x - h)² + k

Here, (h, k) is the vertex of the parabola.

Vertex of the parabola → x = 3, y = 13

Axis of symmetry → x = 3
