Do you still want it as a fraction or a decimal?
If you want it as a fraction:
54/100= 27/50
72/100=36/50=18/25
90/100=45/50
In decimals:
54/100=0.54
72/100=0.72
90/100=0.90

In 54/100, 2 is the only common factor. Dividing 54 and 100 both by 2, we get 27/50. This is the simplest form of 54/100. Note that 54/100=0.54.

In 90/100, 10 is the only common factor. Divide both 90 and 100 by 10. We get 9/10. That's the simplest form.

Answer:

Length ≈ 31cm

Width ≈ 10cm

Step-by-step explanation:

$Let -the-length-be : x\\Let-the-width-be :y\\\\According- to- the- question ; \\x = 3(y)\\x=3y ---------(1)\\2(l+w)=82\\2(x+y)=82\\2x+2y =82 --------(2)\\Substitute- the - given- value- for ; x -in - equation---(1) into -equation (2)\\2(3y)+2y =82\\6y+2y=82\\8y =82\\\frac{8y}{8} =\frac{82}{8} \\y = 10.25\\\\Substitute 10.25 -for ;y -in -eq 1\\x=3y ---------(1)\\x = 3(10.25)\\x = 30.75$

CHECK

$Length =31\\Width = 10\\P = ?\\P= 2(l+w)\\P = 2(31+10)\\P = 2(41)\\P= 82cm$

Answer:

(A) The rate of change in the price of a bushel of corn in the current year is $7.

(B) The price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.

Step-by-step explanation:

The graph for the prices of different numbers of bushels of corn at a store in the current year is shown below.

Part A:

The rate of change in the price of a bushel of corn in the current year based upon the number of bushels is known as the slope of the line.

The formula to compute the slope is:

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

Consider the ordered pairs: (4, 28) and (10, 70)

Compute the slope of the line as follows:

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

$=\frac{70-28}{10-4}\\\\=\frac{42}{6}\\\\=7$

Thus, the rate of change in the price of a bushel of corn in the current year is $7.

Part B:

The data for the price of bushels in the previous year is as follows:

Number of Bushels Price

2 10

4 20

6 30

8 40

Compute the rate of change in the price of a bushel of corn in the previous year based upon the number of bushels as follows:

Consider the ordered pairs: (2, 10) and (6, 30)

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

$=\frac{30-10}{6-2}\\\\=\frac{20}{4}\\\\=5$

The rate of change in the price of a bushel of corn in the previous year is $5.

Thus, the price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.

PLEASE HELP!!!<br> In the figure below, m <br> Part A: Determine m <br> Part B: Are

SCORPION-xisa [38]

Step-by-step explanation:

Part A :-

m(a) , m(b) & m(c) when will get combined ; they will form a straight angle (180°) .

So,

m(a) + m(b) + m(c) = 180°

=> 3x + 5 + 5x - 18 + 7x - 2 = 180°

=> 15x - 15 = 180°

=> 15(x - 1) = 180°

=> x - 1 = 180 / 15

= 12°

=> x = 12 + 1

= 13°

Using the value of x gives the value of m(a) , m(b) & m(c) .

• m(a) = 3 × 13 + 5 = 39 + 5 = 44°

• m(b) = 5 × 13 - 18 = 65 - 18 = 47°

• m(c) = 7 × 13 - 2 = 91 - 2 = 89°

Part B :-

Complementary angles are the pair of angles whose sum is 90° . Here sum of m(a) & m(b) is

44 + 47 = 91°. Hence they are not complementary angles.

A cylindrical container of three rubber balls has a height of 18 centimeters and a diameter of 6 centimeters. each ball in the c

You have 3 spheres inside a cylinder like for a can of tennis balls. Notice the radius of the cylinder is 3 cm, the same as the radius of the spheres, so the spheres just fit width wise, and 3 spheres height would be 6 radius lengths or 18, which is the same as the cylinder height, so the three spheres are packed to the best fit.

The volume not occupied by the spheres will be the total cylinder volume take away the three spheres volumes.

The cyinder volume with height h=18 and radius r=3 will be approx..
$V cyl= \pi r^2h = \pi *3^2*18 = 508.7 ~cm^3$

The volume of 3 spheres with radius r=3 will be
$3*V sph=3* \frac{4}{3} \pi r^3=3* \frac{4}{3} \pi *3^3=339.12~cm^3$

The volume unoccupied by the spheres inside the cylinder is the difference in those two volumes..
508.68 - 339.12 = 169.56 or 170 cubic centimeters
