solve an equation with two real solutions practice

Answers

Answer 1

Answer:

x=2.5

Step-by-step explanation:

bring all terms to one side

[tex]4x^{2} -20x+25=0[/tex]

factor it

[tex](2x-5)^{2}=0[/tex]

2x-5=0

2x=5

x=2.5

Answer 2

Answer:

20/33

Step-by-step explanation:

4*2-13x=7x-25

8-13x=7x-25

(subtract 7 x's)

8-20x= -25

A sphere has a diameter of 11 inches. What is its surface area? Use 3.14 to approximate π. Round to the nearest hundredth if necessary.

Answers

Answer:

The surface area is [tex]379.94in^2[/tex]

Step-by-step explanation:

Given

Shape: Sphere

[tex]D= 11\ in[/tex] - -- Diameter

Required

Determine the surface area (A)

This is calculated using:

[tex]A = 4\pi r^2[/tex]

Where

[tex]r = \frac{1}{2}D[/tex]

[tex]r = \frac{1}{2}*11[/tex]

[tex]r = 5.5[/tex]

So, we have:

[tex]A = 4 * 3.14 * 5.5^2[/tex]

[tex]A = 4 * 3.14 * 30.25[/tex]

[tex]A = 379.94[/tex]

Hence, the surface area is [tex]379.94in^2[/tex]

Answer:

379.94

Emma has already taken 6 pages of notes on her own, and she will take 4 pages during each hour of class. Write an equation that shows the relationship between the time in class (h) and the number of pages (p).

Answers

Answer:

6 + (p x h)

Step-by-step explanation:

well, Emma already has the 6 pages so we can push that to the side, but for every hour, she will write 4 more pages, so it would be p x h, but that’s most importnant so you put that in parentheses so you can add the 6 back later.

nancy lives on a corner lot. cutting across a lot that is 36 feet, and 8 ft longerthan the width.find the length and width if the lot

Answers

Answer:

The length of the lot is 13 feet, and the width is of 5 feet.

Step-by-step explanation:

Perimeter of a rectangle:

The perimeter of a rectangle of length l and width w is given by:

[tex]P = 2(l + w)[/tex]

Lot of 36 feet:

Rectangular, so [tex]P = 36[/tex]

Length 8 feet longer than the width:

This means that [tex]l = 8 + w[/tex]

Finding the width:

[tex]P = 2(l + w)[/tex]

[tex]2(8 + w + w) = 36[/tex]

[tex]16 + 4w = 36[/tex]

[tex]4w = 20[/tex]

[tex]w = \frac{20}{4}[/tex]

[tex]w = 5[/tex]

Finding the length:

[tex]l = 8 + w = 8 + 5 = 13[/tex]

The length of the lot is 13 feet, and the width is of 5 feet.
