If a polygon has an area of 25cm and is dilated by a factor of 3, what will be the area of the dilated polygon?

Answers

Answer 1

Answer:

225 cm²

Step-by-step explanation:

dilatation factor = 3 , then

area factor = 3² = 9

the area of the dilated polygon is then 9 times the area of the original so

area of dilated polygon = 9 × 25 = 225 cm²

Jillian is trying to determine what helium tank pressure she needs to fill balloons for the student council dance. Find the unknown numbers in the table until you find the best answer to the question.

Which cylinder pressure will Jillian need if she plans to fill 90 balloons?

Answers

According to the typical Helium Cylinder/Balloon Chart, she will need 300 pounds of pressure to fill 90 balloons. Option D is correct.

What is pressure?

The force applied perpendicular to the surface of an item per unit area across which that force is spread is known as pressure. The force involved vertically to the surface of an object per unit area is pressure.

It is denoted by P. The pressure relative to the ambient pressure is known as the gauge pressure.

Jillian is trying to determine what helium tank pressure she needs to fill balloons for the student council dance. Find the unknown numbers in the table until you find the best answer to the question. Which cylinder pressure will Jillian need if she plans to fill 90 balloons? Tank Pressure and Balloon Quantity Pressure in the helium cylinder (psi) Number of 9-inch balloons 100 30 150 ? 200? 250? 300?

According to the typical Helium Cylinder/Balloon Chart, she will need 300 pounds of pressure to fill 90 balloons (PSI.)

Simply divide the number of balloons by the total PSI to arrive at this figure.

⇒990/300

⇒3.333333 psi each.

The no of the 90-inch balloon is found as;

⇒3.33333 × 90

⇒300

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The value of f(x) when the value of x is 9 is 38.

What is the equation of a line?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The given data points are in a linear relation, therefore, if we find the slope of the line on which these data points will be located. Then the slope will be,

m = (17-5)/(2+2) = 3

Now, equate any point and the slope in the general equation of line, therefore, the equation will be,

y = 3x + c

17 = 3(2) + c

17 - 6 = c

c = 11

Further, the value of f(x) when the value of x is 9 will be,

f(x) = 3x + 11

f(9) = 3(9) + 11

f(9) = 38

Hence, the value of f(x) when the value of x is 9 is 38.

The ratio 7 to 16 is greater than 6:8.
The ratio 6:8 is greater than the ratio 7 to 16.

Answers

The correct options are Option A: the ratio 7 to 16 should show 7 cells shaded and Option D: 6:8 is also greater than 7:16.

The ratio is the representation of the fraction where the fraction is represented by : symbol.

In the ratio a:b, it simplifies that a number of parts are shades among b number of cells.

Here given two ratios are 7:16 and 6:8.

The ratio 7:16 simplifies that 7 cells are shaded from 16 number of cells.

similarly, 6:8 simplifies that 7 cells are shaded from 8 number of cells.

As 6:8 and 7:16 can be written as in the fraction form which are 6/8 and 7/16.

Then multiply 2 in both denominator and numerator of 6:8 will be

6/8= 12/16

Now comparing between 12/16 and 7/16

12/16 > 7/16 as the denominator is same and the numerator is greater in 12/16.

Then 6:8 is also greater than 7:16.

So by checking all the options

Option A  is correct:  from above i is clear that the ratio 7 to 16 should show 7 cells shaded.

Option D is correct: 6:8 is also greater than 7:16.
