27 is 144 percent of what

1 answer:

7 0

27 is 144 percent of what. Let the what be x.

27 = 144% of x

27 = (144/100)x

(144/100)x = 27

1.44x = 27 Divide through

x = 27/1.44 Use your calculator

x = 18.75

Therefore 27 is 144 percent of 18.75

What is the slope of this graph

Masja [62]

Answer:

Slope, m = 5

Step-by-step explanation:

Picking points on the x-axis and y-axis of the graph;

Point on x-axis (x1, x2) = 2, 4

Points on the y-axis (y1, y2) = 10, 20

To find the slope;

Mathematically, slope is given by the formula;

$Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis}$

$Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}}$

Substituting into the equation, we have;

$Slope, m = \frac {20 - 10}{4 - 2}$

$Slope, m = \frac {10}{2}$

Slope, m = 5

The area of the rectangular floor in Tamara’s room is 9556 square feet. The width of the room is 813 feet. Part A Round each mea

denis23 [38]

Answer:

Area of Tamara room

=9556 square feet

Width

=813 feet

Length= 11.75 feet

Total area= 19794 square feet

480 square feet will not be enough

Step-by-step explanation:

Dimensions of Tamara's room to the nearest whole numbers

Area of Tamara room

=9556 square feet

Width

=813 feet

For the length

Length*width= area

Length= area/width

Length= 9556/813

Length= 11.75

To the nearest whole number = 12 feet

The ceiling is 12 feet high

Let's calculate for the area of the combination

1)Height and width two times

2)Height and length two times

1).area = 12*813

= 9756

Then 9756*2= 19512

2). area= 12*11.75

= 141

Then 141*2= 282

Total area = 282+19512

Total area= 19794

The perimeter of a particular square and the circumference of a particular circle are equal. What is the ratio of the area of th

Tasya [4]

Ratio of the area of the square to the area of the circle is $\frac{\pi}{4} : 1$

In terms of fraction $\frac{\pi}{4}$

Solution:

Given that perimeter of a particular square and the circumference of a particular circle are equal

To find: ratio of the area of the square to the area of the circle

Let the side of square be "a" and radius of circle be "r"

The perimeter of square is given as:

Perimeter of square = 4a

The circumference of circle is given as:

Circumference of circle = 2πr

From given,

perimeter of a particular square and the circumference of a particular circle are equal

perimeter of a particular square = circumference of a particular circle

$4a = 2 \pi r\\\\a = \frac{\pi r}{2}$

We need to find the ratio of the area of the square to the area of the circle.

We know that,

$\text{ Area of the square }= a^2\\\\\text{ Area of the circle }= \pi r^2$

Ratio of area of square to area of circle = $a^2 : \pi r^2$

Substituting the value of $a = \frac{\pi r}{2}$ in above ratio,

Ratio of area of square to area of circle = $(\frac{\pi r}{2})^2 : \pi r^2$

On reducing to lowest terms we get,

⇒ $\frac{\pi^2 r^2}{4} : \pi r^2 = \frac{\pi}{4} : 1$

In terms of fraction we get,

$\frac{\pi}{4} : 1 = \frac{\frac{\pi}{4}}{1} = \frac{\pi}{4}$

Thus ratio of the area of the square to the area of the circle is $\frac{\pi}{4} : 1$
