Answer 1

Answer:

Ravi and Courtney

Step-by-step explanation:

Simplifying the equations

Penny

2x - y = -1y = 2x + 1

Ravi

2x + 3y = 33y = -2x + 3y = -2/3x + 3

Courtney

-4x - 6y = -66y = -4x + 6y = -2/3x + 3

Edwin

6x + 6y = 96y = -6x + 9y = -x + 9

Ravi and Courtney would have infinitely many solutions because they are the same equation.

Answer 2

Answer:

Ravi and Courtney have the same equation so they will have infinetely many solutions.

Step-by-step explanation:

Step 1:  Solve each equation for y

Penny → [tex]2x - y = 1[/tex]

           → [tex]-y + 2x - 2x = 1 - 2x[/tex]

           → [tex](-y) * -1 = (1 - 2x) * -1[/tex]

           → [tex]y = 2x - 1[/tex]

Ravi → [tex]2x + 3y = 3[/tex]

       → [tex]3y + 2x - 2x = 3 - 2x[/tex]

       → [tex](3y)/3 = (3 - 2x)/3[/tex]

       → [tex]y = -2/3x + 1[/tex]

Courtney → [tex]-4x - 6y = -6[/tex]

                → [tex]-6y - 4x + 4x = -6 + 4x[/tex]

                → [tex](-6y)/-6 = (-6 + 4x)/-6[/tex]

                → [tex]y = -2/3x + 1[/tex]

Edwin → [tex]6x + 6y = 9[/tex]

           → [tex]6y + 6x - 6x = 9 - 6x[/tex]

           → [tex](6y)/6 = (9 - 6x)/6[/tex]

           → [tex]y = -x + 1.5[/tex]

Answer: Ravi and Courtney have the same equation so they will have infinetely many solutions.

Which is the expression is equivalent to 27/125
a (3/5)3
b 3/5'3
c (3/4)2
d(3'3/5'5)

Answers

Answer:

a

Step-by-step explanation:

(3/5)^3= 27/125

So a is the correct answer

Answer:

Answer option D.

I'm assuming you meant (3/5)'3 for option A.(3/5)^3 also known as (3/5)'3 in your case.

If we simplify the expression (3/5)^3 we can see that ^3 means you cube both the numerator and the denominator since 3/5 is in parenthesis.

Numerator:

3 cubed(3^3) would result in

= 9

Denominator:

5 cubed(5^3) would result in

= 125

Hence, you'll get 9/125.

So your answer is;

A, (3/5)'3

A force of 61 N is applied to an area of 750 cm2.
Calculate the pressure in N/m2.
Give your answer to the nearest integer.

Answers

Answer:

813.33 N/m²

Step-by-step explanation:

Before finding the answer to this, let us convert 750cm² to m².

1 m ⇒ 100cm

1 m × 1 m ⇒ 100 cm × 100 cm

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

1 m² ⇒ 10000 cm²

 x    ⇒ 750 cm²

Let us use cross multiplication to find the value of x.

10000x = 750 × 1

10000x = 750

x = 750/10000

x = 0.075

∴ 750 cm² = 0.075 m²

And now let us find the pressure.

Pressure = Force ÷ Area

Pressure = 61 N ÷ 0.075 m²

Pressure = 813.33 N/ m²

y - 2 = [tex]\frac{1}{3}[/tex] x ( multiply both sides by 3 to clear the fraction )

Which is the general form of the equation of the circle shown? x2 y2 4x – 2y – 4 = 0 x2 y2 4x – 2y 2 = 0 x2 y² – 4x 2y – 4 = 0 x2 y² – 4x 2y 2 = 0

Answers

The general equation that represents the circle is x² + y² + 8x - 18y + 72 = 0

How to determine the circle equation?

The center of the circle is given as:

Center, (a,b) = (-4,9)

The diameter is given as:

d = 10

Calculate the radius (r)

r = 10/2 = 5

The circle equation is then calculated using:

(x - a)² + (y - b)² = r²

So, we have:

(x + 4)² + (y - 9)² = 5²

Expand

x² + 8x + 16 + y² - 18y + 81 = 25

Collect like terms

x² + y² + 8x - 18y + 16 + 81 - 25 = 0

Evaluate

x² + y² + 8x - 18y + 72 = 0

Hence, the general equation that represents the circle is x² + y² + 8x - 18y + 72 = 0

how mant cubic centimeters of air would be needed to completely fill a soccer ball with a radius of 15cm?

Answers

Answer:

14137.17 cubic cm

Step-by-step explanation:

I can see that the radius here is 15cm, and when it says air, I am going to guess we are looking for the volume. We do the equation in order to get the volume, and get the answer 14137.17cm.

IMPORTANT : When it says air-  you have to realize it's VOLUME.

given:

radius= 15 cm

to find:

the amount of cubic centimeters of air needed to fill the soccer ball.

solution:

[tex]v = \frac{4}{3} \pi {r}^{3} [/tex]

[tex]v = \frac{3}{4} \times \pi \times {(15)}^{2} [/tex]

[tex]v = 14137.17 {cm}^{3} [/tex]

therefore, the soccer ball can hold 14137.17 cubic centimeters of air.

The probability of an event is P(A) = 0.05 What is the complement of P(A)?

Answers

Probability is the likelihood or chance that an event will occur. The complement of the probability will be 0.95

What is probability?

Probability is the likelihood or chance that an event will occur. Mathematically:

Probability = expected outcome/total outcome

Given that the probability of an event is P(A) = 0.05, the complement will be expressed as:

P'(A) = 1 - P(A)
P'(A) = 1 - 0.05
P' (A) = 0.95

Hence the complement of the probability will be 0.95
