Answer:

47.71

Step-by-step explanation:

Two "special" triangles are involved.

ΔSWR is a 30°-60°-90° right triangle, so will have sides in the ratio 1 : √3 : 2.

ΔUVW is a 45°-45°-90° right triangle so will have sides in the ratio 1 : 1 : √2.

For ΔSWR, the side SW is given as 6, so the other sides are ...

WR = 6√3

RS = 2(6) = 12

For ΔUVW, the side WU is given as 8, so the other sides are ...

UV = VW = 8/√2 = 4√2

Then the perimeter of the figure is ...

P = RS +ST +TU +UV +VW +WR

P = 12 +8 +6 +4√2 +4√2 +6√3 ≈ 47.71

Lshonda sells beaded necklaces. Each large necklace sells for 4.70 and each small necklace sells for 4.20. How much will she ear

AysviL [449]

Answer: Lshonda will earn $23.

Step-by-step:
The equation would be (4•4.7) + (1•4.2)
4 multiplied by 4.7 is 18.8
1•4.2 is 4.2
18.8+4.2=23

hope this helps! :)

If one kg. of potatoes costs $4.99, what would 1.8 kg cost?

lina2011 [118]

You can use the proportion.
$4.99 / 1 kg = x / 1.8 kg
x = ($4.99 * 1.8 kg) / 1 kg
x = $8.98

Therefore, in 1.8 kg of potatoes, it costs at $8.98

WORDED QUADRATIC EQUATION!!! PLS HELP <br><br> MOSTLY NUMBER 5 PLS

pav-90 [236]

Answer:

7,11

Step-by-step explanation:

The width is x. x+4= the length. The area is side times side, so it’s

x × (x+4) = 77

We can simplify this to:

x × x + x × 4 = 77

x^2 + 4x = 77

x^2 + 4x - 77 = 0 This is a quadratic equation. So we can solve using the quadratic formula:

x = $\frac{-4\pm\sqrt{4^2-4\cdot1\cdot-77}}{2\cdot1}$ ->

$\frac{-4\pm18}{2}$

$\frac{14}{2} \implies7$

That’s the positive solution and that’s x, the width. So the width is 7 and the length is 7+4=11

1.5d + 3.25 = 1 + 2.25d ---What are the steps to find x?

yuradex [85]

Do u mean d?

1.5d +3.25 = 1 +2.25d
3.25 = 1 + .75d -1.5d on both sides
2.25 = .75d subtraction 1 on both sides
3 = d divide both sides by .75
