Answer:

The inequality is $39.25p + $9.50 ≤ $245

and the amount of people that can come to the amusement park is 6

Step-by-step explanation:

when you subtract 9.50 from both sides, you get

39.25p ≤ 235.5

then you divide 39.25 by both sides, and you will get 6

Answer:

285°

Step-by-step explanation:

90 + 180 = 270

270 + 15 = 285

Answer:

285°

Step-by-step explanation:

Lets solve your problem :)

90° + 180° = 270°

270° + 15° = 285°

Answer:

32 pieces

Step-by-step explanation:

1 - 3/8 = (8 - 3) / 8 = 5/8

3/8 = 12 pieces

5/8 = x

Cross multiply

3/8 x = 12 * 5/ 8

3/8 x = 7.5

x = 20

Hence, total piece cake was cut into originally :

20 + 12 = 32 pieces

Answer:

1) The volume of the frustum is 27·(√3)·h

2) The surface area the frustum is 24·h + 54·√3

Step-by-step explanation:

1) A frustum of the regular triangular prism is a portion of the triangular prism

The length of the edge of the triangle prism = 12

The area of the triangular face, A = (√3/4)·a²

∴ A = (√3/4)·12² = 36·√3

When

The volume of the triangular prism, V = A·h = (36·√3)·h

By triangle proportionality theorem, the cross sectional area of the top half of the triangular prism =  (√3/4)·6² = 9·(√3)

The volume of the top half, V₂ = 9·(√3)·h

The volume of the frustum = V - V₂ = (36·√3)·h - 9·(√3)·h = 27·(√3)·h

The volume of the frustum = 27·(√3)·h

2) The surface area of the triangular side of the frustum is given as follows;

A = 36·√3- 9·(√3) = 27·(√3)

The surface area the frustum, [tex]F_A[/tex] = 2×27·(√3) + 2 ×6 ×h + 12×h = 24·h + 54·√3

The surface area the frustum = 24·h + 54·√3

Answer:

B, 3/10

Step-by-step explanation:

Going by SOHCAHTOA, we see that tangent is actually Opposite / Hypotenuse.

The opposite side of angle A here is 12, while the Hypotenuse is 40. Our answer is 12/40 which is 3/10.

Answer:

if Eric house is in the same quadrant as the library then the coordinates will be (-2,4)

Answer:

(-2, 4) is also in the second quadrant

Step-by-step explanation:

The library is in the second quadrant, at the point (-3, 5), where the x-coordinate is negative and the y-coordinate is positive.  Among the four given points, only (-2, 4) is also in the second quadrant.

Answer:

Infinite solutions.

Step-by-step explanation:

Let's solve your system by substitution.

3y=9x+15;3x−y=−5

Rewrite equations:

3x−y=−5;3y=9x+15

Step: Solve 3x−y=−5 for y:

3x−y=−5

3x−y+−3x=−5+−3x(Add -3x to both sides)

−y=−3x−5

−y   −1   −1=−3x−5

(Divide both sides by -1)

y=3x+5

Step: Substitute 3x+5 for y in 3y=9x+15:

3y=9x+15

3(3x+5)=9x+15

9x+15=9x+15(Simplify both sides of the equation)

9x+15+−9x=9x+15+−9x(Add -9x to both sides)

15=15

15+−15=15+−15(Add -15 to both sides)

0=0

Hello lucker

Answer:

Step-by-step explanation:

Rationalize the denominator of b. So, multiply the numerator and denominator by [tex]\sqrt{x}[/tex]

[tex]b = \frac{(1-2\sqrt{x}) *\sqrt{x}}{\sqrt{x}*\sqrt{x} }=\frac{1*\sqrt{x} -2\sqrt{x} *\sqrt{x} }{\sqrt{x} *\sqrt{x} }\\\\=\frac{\sqrt{x} -2x}{x}\\[/tex]

Now, find a +b

[tex]a +b = \frac{2x+\sqrt{x} }{x}+\frac{\sqrt{x} -2x}{x}\\\\=\frac{2x+\sqrt{x} +\sqrt{x} -2x}{x}[/tex]

Combine like terms

[tex]= \frac{2x-2x+\sqrt{x} +\sqrt{x} }{x}\\\\=\frac{2\sqrt{x} }{x}[/tex]

Now find (a + b)²

(a +b)² = [tex](\frac{2\sqrt{x} }{x})^{2}[/tex]

          [tex]= \frac{2^{2}*(\sqrt{x} )^{2}}{x^{2}}\\\\= \frac{4* x}{x^{2}}\\\\= \frac{4}{x}[/tex]

Hint: [tex]\sqrt{x} *\sqrt{x} =\sqrt{x*x}=x[/tex]
