Answer:

A. 40

Step-by-step explanation:

CP= x, SP= £36, sale= 10%

SP= CP- 10%= CP*0.9

x*0.9= £36

x= £36/0.9= £40

Answer:

g(x)=3^x-4, this one is exponential so it would have the greatest rate of change as x approaches infinity. The first one is a line and the third one is a parabola.

Step-by-step explanation:

Answer:

[tex]g_{n}=g_{n-1} *-3[/tex]

Step-by-step explanation:

A recursive formula is [tex]g_{n}=g_{n-1} *r[/tex].  N is the number of terms and r is the rate of change.  R here equals -3 because you are multiplying by -3 eachtime.  Therefore, the recursive formula is [tex]g_{n}=g_{n-1} *-3[/tex]

Answer:  6x^2 +28x + 32

Step-by-step explanation: FOIL

First: 2x × 3x = 6x^2

Outside:2x × 8 = 16x, and Inside: 3x × 4 = 12x Combine those to get +28x

Last: 4 × 8 = 32

Put them together in order 6x² + 28x + 32

Answer:

c: 5 x 3/5

Step-by-step explanation:

so the is 15 blocks shaded on the 25 grid

so i would work out each fraction answer and find which one makes 15/25

5 x 5/3 = 25/25

3/5 + 3/5 + 3/5 + 3/5 + 3/5 + 3/5 = 21/5

5 x 3/5 = 15/25

hope this helps :)

if the answer is wrong plz comment and i will fix thanks :)

Answer:

c) 5x3/5

Step-by-step explanation:

Look at one of the bars only. We see that 3 blocks out of 5 are colored in.

So that means the fraction is 3/5. But since there are 5 bars, we must multiply the fraction by 5.

Therefore, the answer is c) 5x3/5

hope this helped:)

Answer:

The time it takes for the ship to travel from Earth to Pluto is 164,337 hours.

Step-by-step explanation:

The question is:

The distance from Earth to Pluto is approximately 5,751,800,000 km. How long does it take for a ship traveling at 35,000 km / h?

Solution:

The formula to compute the time (t) it takes to travel a certain distance (d) at a certain speed (s) is:

[tex]t=\frac{d}{s}[/tex]

It is provided that:

d = 5,751,800,000 km

s = 35,000 km / h

Compute the time it takes for the ship to travel from Earth to Pluto as follows:

[tex]t=\frac{d}{s}[/tex]

  [tex]=\frac{5751800000}{35000}\\\\=164337.14286\\\\\approx 164337[/tex]

Thus, the time it takes for the ship to travel from Earth to Pluto is 164337 hours.

Answer:

the distance y between the bottom right corner of the blue square and the right side of the yellow square directly next to the corner is 1.3cm

Step-by-step explanation:

From the information given;

A blue square is placed inside a large yellow square and the centres of the squares are aligned one over the other

So ; if one side of the  square is (3x + 2)cm  (i.e the blue side)

the  other side is (8 - x)cm  (i.e the yellow sides)

since the two shapes given are squares ; we can say that:

(3x+2)= (8 - x)

3x +x = 8 -2

4x = 6

x = 6/4

x = 1.5

Let replace x = 1.5 for the sides of the square and find the actual length of the square sides.

So, for the yellow side; we have:

= (8 - x)cm

= (8 - 1.5 ) cm

= 6.5 cm

We all know that the area of the square = l²

then the area of the yellow side = (6.5 cm )²

the area of the yellow side = 42.25 cm²

Let y be the distance between the bottom right corner of the blue square and the right side of the yellow square directly next to the corner

Since the blue region is inside the yellow region; to calculate for the side of the blue region ; we have:

(6.5y -y+y) cm

(6.5 - 2y )cm

The area of the blue side =( (6.5 - 2y )cm)²

The area of the blue side =  (6.5 - 2y )² cm²

However; we are also given that :

the area of the blue square is 36% the area of the yellow square.

Thus;

(6.5 - 2y )² = 36/100 × 42.25

(6.5 - 2y )² =  0.36  × 42.25

(6.5 - 2y )² =  15.21

(6.5 - 2y ) = [tex]\sqrt{15.21}[/tex]

(6.5 - 2y ) = 3.9

6.5 - 2y = 3.9

6.5 - 3.9 = 2y

2.6 = 2y

y = 2.6/2

y = 1.3 cm

Therefore , the distance y between the bottom right corner of the blue square and the right side of the yellow square directly next to the corner is 1.3cm

Answer:

La mayor tiene 61 años.

Step-by-step explanation:

Sea x,y,z la edad de la mayor, intermedio y la menor respectivamente.

Tenemos las siguientes ecuaciones:

[tex]x+y+z=127[/tex] (la suma de las edades es 127)

[tex]x = z+30[/tex] (la mayor tiene 30 años más que la menor)

La frase "y la del intermedio 26 menos que la menor" no tiene sentido, puesto que esto implicaría que la del intermedio es menor que la menor. Luego se asume que la frase ha de ser "y la del intermedio 26 menos que la mayor"

[tex]x-26 = y[/tex] (la del intermedio tiene 26 menos que la mayor).

La segunda ecuación se traduce a x-30 =z. Si reemplazamos todo en la primera ecuación obtenemos

[tex]x+(x-26)+(x-30) = 127[/tex]

Obtenemos la ecuación

[tex]3x-56 = 127[/tex]

Sumando 56 a ambos lados y dividiendo por 3, obtenemos

[tex] x = \frac{127+56}{3} = 61[/tex]

Es decir la mayor tiene 61 años.

Answer:

see explanation

Step-by-step explanation:

To find the x- intercepts let f(x) = 0, that is

x² + 12x + 11 = 0 ← in standard form

(x + 1)(x + 11) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 11 = 0 ⇒ x = - 11

The x- intercepts are x = - 11 and x = - 1

To find the y- intercept let x = 0, that is

f(0) = 0² + 12(0) + 11 = 0 + 0 + 11 = 11

The y- intercept is 11

Answer:

The answer is 150.

Step-by-step explanation:

Eliminate the second and third piece of the function, because they do not include t= -10 in their range. Now, input t= -10 in the first piece. That will give you f(-10)= (-10)^2 - 5(-10)= 150.

Answer:

B.) Perimeter = 126 cm, area = 972 cm²

Step-by-step explanation:

==>Given:

Rectangle with the following dimensions:

L = 8 cm

W = 6 cm

==>Required:

Perimeter and area of the rectangle if enlarged using a scale factor of 4.5.

==>Solution:

The dimensions of the rectangle when enlarged by a scale factor of 4.5 would be:

L = 8 × 4.5 = 36cm

W = 6 × 4.5 = 27cm

=>Area = L × B

= 36 × 27

Area = 972 cm²

=>Perimeter = 2(L + W)

= 2(36 + 27)

= 2(63)

Perimeter = 126 cm

Answer:

Step-by-step explanation:

Each equation is in vertex form, so you can easily determine the number of real roots. The leading coefficient tells you whether the parabola opens upward (positive) or downward (negative).

  y = a(x -h)^2 +k

has leading coefficient "a" and vertex (h, k).

__

f(x) = 1/3(x +5)^2 +7

  vertex: (-5, 7), opens downward

The vertex is above the x-axis, so there are two real roots.

__

f(x) = -5(x -3)^2

  vertex: (3, 0), opens downward

The vertex is on the x-axis, so there is one real root.

Answer:

x> 1/6

Step-by-step explanation:

-2(8x – 4)< 2x + 5

Distribute

-16x +8 < 2x+5

Add 16x to each side

-16x +8+16x < 2x+16x+5

8 < 18x+5

Subtract 5 from each side

8-5 < 18x

3 < 18x

Divide each side by 18

3/18 < 18x/18

1/6 < x

Answer:

[tex]x > \frac{1}{6} [/tex]

First answer is correct.

Step-by-step explanation:

[tex] - 2(8 x - 4) < 2x + 5 \\ - 16x + 8 < 2x + 5 \\ - 16x - 2x < - 8 + 5 \\ - 18x < - 3 \\ \frac{ - 18x}{ - 18} < \frac{ - 3}{ - 18} \\ x > \frac{1}{6} [/tex]

Answer:

12 red marbles

Step-by-step explanation:

You make an equation: 3x+4x=21

Then, you get 7x=21.

By using algebra, you get x=3.

Then you muliply 3 by 4 since the ratio of red marbles is 4.

So you get 12.

Answer:

There are 12 red marbles

Step-by-step explanation:

green : red : total

3           4       3+4=7

We want a total of 21

21 /7 =3

Multiply by 3

green : red : total

3*3       4*3   7*3

 9         12     21

Answer:

h = 2.5

Step-by-step explanation:

250 + 200h = 300 + 180h

250 + 200h - 180 = 300 + 180h - 180

250 + 20h = 300

250 - 250 + 20h = 300 - 250

20h = 50

20h ÷ 20 = 50 ÷ 20

h = 2.5

Answer:

85.84 ft²

Step-by-step explanation:

The surface area of the fabric would be the total net area of the shape of the tent covered.

Thus, surface area = area of the 3 rectangular faces + area of the 2 triangular faces

From the diagram given, the 3 rectangular faces have the same dimensions as follows:

L = 6ft

W = 4ft

Area of the 3 rectangular faces = 3(6*4) = 3(24) = 72ft²

The 2 triangular faces have the same dimensions as follows:

B = 4f

H = 3.46ft

Area of the 2 triangular faces = 2(½*B*H)

= 2(½*4*3.46)

= 2(2*3.46)

= 2(6.92)

= 13.84 ft²

Surface area of fabric used to cover the triangular tent = 72ft² + 13.84ft² = 85.84 ft²

Answer:

85.84

Step-by-step explanation:

The experimental probability is what you actually rolled

24/60 = 2/5 = 40%

The theoretical probability is what we expect to happen

=number of even numbers / total number of numbers

3/6 = 1/2 = 50%

Answer:

10=.50n+1.50

Step-by-step explanation:

The total cost, c, of n chicken wings can be represented by a system of equations as follows c = 0.50n + 1.50

c = total cost

n = number of chicken wings

Therefore,

The cost of chicken wing at restaurant Z is $0.50 per wings plus a one time $1.50 charge for sauce.

The system of equation that represent the system is as follows:

c = 0.50n + 1.50

The one time fee for sauce is just like a constant in the equation.
