The length of the rectangle is increased by 10%.
jonny [76]

Answer:

8% increase

Step-by-step explanation:

The length after the increase:

30 x 1.1 = 33cm

The width after the increase:

20 x 1.05 = 21cm

New perimeter:

2(33 + 21) = 108 cm^2

Old perimeter:

2(30 + 20) = 100 cm^2

Percentage increase of area:

108 / 100 = 1.08 = 8% increase

The volume of a cylinder is 1000 cubic meters. The radius is 8.5 meters. Determine the height of the cylinder. Use 3.14 for \piπ
finlep [7]

Answer:

<u>4.4 m</u>

Step-by-step explanation:

Formula :

Volume (cylinder) = πr²h

Solving :

  • 1000 = 3.14 x (8.5)² x h
  • 1000 = 3.14 x 72.25 x h
  • 1000 = 226.865h
  • h = 1000/226.865
  • h = <u>4.4 m</u>

Arrange the equations in increasing order of the value of their solutions.
Ulleksa [173]

See the explanation

<h2>Explanation:</h2>

The complete question is attached below. In order to solve this problem, we'll use a graphing tool. First of all, we'll say that the LHS is a linear function and the RHS is another linear function, so for each case, we'll have:

f(x)=g(x)

For each graph, f(x) will be drawn in red while g(x) will be drawn in blue.

Case 1:

f(x)=\frac{1}{4}x+\frac{5}{2}x-2 \\ \\ g(x)=4-\frac{1}{4}x

So by equating both equations:

\frac{1}{4}x+\frac{5}{2}x-2=4-\frac{1}{4}x

By using graphing tool we get a point of intersection at which the x-value is the solution to our equation. So:

<u>Solution:</u>

\boxed{x=2}

See First Figure below.

Case 2:

f(x)=7.9x+x+4 \\ \\ g(x)=-1.1x-16

Applying a similar method as in case 1.

<u>Solution:</u>

\boxed{x=-5.8}

See Second Figure below.

Case 3:

f(x)=3.2x+5.7 \\ \\ g(x)=-2.5x

Applying a similar method as in case 1.

<u>Solution:</u>

\boxed{x=-1}

See Third Figure below.

Case 4:

f(x)=10.1x-1.6x+44 \\ \\ g(x)=-7

Applying a similar method as in case 1.

<u>Solution:</u>

\boxed{x=-6}

See Fourth Figure below.
