Answer:

Haley needs to print 65% of the tickets.

Step-by-step explanation:

Given that:

Tickets printed by Haley = 112

Tickets needed to print = 320

Tickets left to print = 320-112 = 208

Percent of tickets left to print = \frac{Tickets\ left\ to\ print}{Total\ tickets}*100

Percent of tickets left to print = \frac{208}{320}*100

Percent of tickets left to print = 0.65*100

Percent of tickets left to print = 65%

Hence,

Haley needs to print 65% of the tickets.

Semmy [17]

Multiply. Distribute 3x to all terms in the parenthesis: x and -8


3x(x) = 3x²

3x(-8) = -24x


3x² - 24x is your answer

Find the possible dimensions of the picture above please
Svetlanka [38]

Answer:

(2x – 7) × (2x + 7)

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) = (4x² – 49) m²

Dimension =?

The picture in the question above has a rectangular shape. Thus, the area is given by:

Area (A) = Length (L) × Width (W)

A = L × W

The dimension of the shape will be:

L × W

Now, we shall determine the dimension (L × W) as follow:

Area (A) = (4x² – 49) m²

Dimension (L × W) =?

A = L × W

L × W = 4x² – 49

Recall:

4 = 2²

49 = 7²

Thus,

L × W = 2²x² – 7²

L × W = (2x)² – 7²

Different of two squares

L × W = (2x – 7)(2x + 7)

L × W = (2x – 7) × (2x + 7)

Dimension = (2x – 7) × (2x + 7)

Therefore, the possible dimension (L × W) of the shape is (2x – 7) × (2x + 7)

RideAnS [48]
For the answer to the question above,
First, let's make the equation,
(1/6) + (1/x) = 1/(3/2) = (2/3) = (4/6)
then
1/x = (3/6) = (1/2)
so the answer would be
x = 2

The ratio of the measures of the three angles is 4:5:6. Find the measure of each angle of the triangle
Furkat [3]

Answer:

Let the number be x.

Given the statement: The ratio of the measure of the three angles is, 4 : 5 : 6.

Then, the angles be 4x , 5x and 6x respectively.

We know that: The sum of all the measures of angles is 180 degree.

then;

4x+5x+6x = 180^{\circ}

Combine like terms;

15x = 180^{\circ}

Divide by 15 both sides we get;

x = 12

Then, the measure of each angle of triangle:

4x = 4(12) = 48^{\circ}

5x = 5(12) = 60^{\circ}

6x = 6(12) = 72^{\circ}
