Answer:

x = 0

Step-by-step explanation:

(x)=5x+19(x)=-2x+15

We move all terms to the left:

(x)-(5x+19(x))=0

We add all the numbers together, and all the variables

x-(+24x)=0

We get rid of parentheses

x-24x=0

We add all the numbers together, and all the variables

-23x=0

x=0/-23

x=0

Answer:

The image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).

Step-by-step explanation:

Let suppose the given point is A(18, 9)

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

Rule to calculate the dilation by a scale factor 1/3 centered at the origin

P(x, y) → P'(1/3x, 1/3y)

Here, P'(1/3, 1/3y) is the image of P(x, y).

Thus,

A(18, 9) → A'(1/3(18), 1/3(9)) = A'(6, 3)

Therefore, the image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).

Answer: Total number of those who took part in the survey (T)=2000

Those who were satisfied (t)=1320

Percentage of those who were satisfied (S)=(t/T)*100

S=(1320/2000)*100

S=66%

Therefore only 66% were satisfied

Answer:

D) 2x+10=40, x= 15 rides

Step-by-step explanation:

Since Paul only bought one ticket, then $10 is the constant of the equation. Since Paul pays $2 per ride, $2 will be the rate/coefficient of the equation.

Since we are solving for x, $40 will be on the right side of the equation

Putting these three facts together, we can make the equation 2x+10=40 which means D is correct

-1

b.

5 + 3(3)=

5 + 9=

14

When x = -2, the value of 5 + 3x is -1,

and when x = 3, the value of 5 + 3x is 14.

Here, we have,

given equation is: 5 + 3x

To evaluate the expression 5 + 3x for the given values of x:

(a) When x = -2:

5 + 3(-2)

= 5 - 6

= -1

(b) When x = 3:

5 + 3(3)

= 5 + 9

= 14

Therefore, when x = -2, the value of 5 + 3x is -1,

and when x = 3, the value of 5 + 3x is 14.

Answer:

2√5 +12 or 16.47213595....

Step-by-step explanation:

Part A - The sum of 2√5 and 3√16 in its simplest form is 2(√5 + 6).

The given numbers are surds.

To find the sum of 2√5 and 3√16, we perform the arithmetic operation of addition on the surds.

So, 2√5 + 3√16 = 2√5 + 3 × 4 (√16 = 4)

2√5 + 3√16 = 2√5 + 12

Factorizing out the factor 2 from both expressions, we have

2√5 + 3√16 = 2√5 + 6 × 2

2√5 + 3√16 = 2(√5 + 6)

So, the sum of 2√5 and 3√16 in its simplest form is 2(√5 + 6).

Part B - The result is irrational.

The result is irrational because 2(√5 + 6) cannot be expressed as a ratio of two integers since √5 is irrational and √5 + 6 is irrational and thus  2(√5 + 6) is also irrational since it cannot be expressed as a ratio of two integers. Also, its decimal representation is non-terminating or repeating.

Thus, the result is irrational.

Answer:

The markup amount is $14 and the retail price is $49.

Step-by-step explanation:

You can use the following formula to find the retail price with the information provided:

Retail price=Cost*(100%+markup %)

Cost=35

Markup %=  40%

Now, you can replace the values in the formula:

Retail price=35*(140%)

Retail price=49

Now, you can subtract the cost from the retail price to find the markup amount:

49-35=14

According to this, the answer is that the markup amount is $14 and the retail price is $49.

16/2=8mm^2 cross section

8*2=16

41.1+16=57.1mm^2

The surface area of the prism is S = 57.1 mm²

The surface area of the prism is calculated as

The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism

Surface Area of the prism = 2B + ph

The area of the triangular prism is A = ph + ( 1/2 ) bh

Given data ,

Let the area of the 2 triangles be T

Let the area of the 2 rectangles be R

Let the area of the third side be U

Now , the total surface area of the prism = T + R + U

where T = 2 x ( 1/2 ) ( 4 x 4 )

T = 16 mm²

R = 2 x ( 3 x 4 )

R = 24 mm²

And , U = 5.7 x 3

U = 17.1 mm²

Therefore , the total surface area of prism S = 16 mm² + 24 mm² + 17.1 mm²

S = 57.1 mm²

Hence , the surface area of prism is S = 57.1 mm²

Answer:

The nike store offers the best deal

The saving per shirt is $2.50

Step-by-step explanation:

Here, we want to compare the prices offered in the two stores

In footlocker, you can get 3 shirts for $55.50

The sales per shirt is thus;

55.5/3 = $18.50

For Nike,

5 shirts for $79.99 which is almost $80

So the price per shirt is $80/5 = $16

We can see that the price at the nike store is better

The difference leading to the savings is;

18.5-16 = $2.50

So you save $2.50 buying from the nike store

Answer:

volume of the new box = 12 x volume of the initial rectangular box

Step-by-step explanation:

Let the length, width and height of the rectangle be represented by l, w and h respectively.

The volume of a rectangle is given as;

volume = l x w x h

             = lwh

From the given question, the dimension of the rectangle are:

new length = l + l = 2l

new width = w + w = 2w

new height = h + h + h = 3h

So that, the volume of the new box is given as;

volume of the new box = 2l x 2w x 3h

                                       = 12 (lwh)

Therefore,

volume of the new box = 12 x volume of the initial rectangular box
