Kai needs to replace the strip laminate that is glued to the vertical faces on a square tabletop. The tabletop is 1.69 m2. What
son4ous [18]

Area of a square = Side x Side (length x width)

A = 1.69 m²

Length = √area of square

L = √1.69 m²

L = 1.3 m

Check Work: 1.3² = 1.3 m x 1.3m

= 1.69 m²

Who knows proportional relationships? and how to solve these both
ExtremeBDS [4]

"Porportional Relationships" means that the rate in which it increases is the same.

For example: 1, 3, 5, 7, 9 is a porportional relationship, because it increases each time by (+2).

Now, look at the first one.

From y to x, y being 2, x being 10, you divided 5 from x to get 2. Next, you divided 6 from 30 to get 5. Because the number dividing is different, it is not proportional

NOT PROPORTIONAL

Look at the second one.

From y to x, y being 12, x being 10, you divided 1.2

Now, look at the next one. 30/25 = 1.2

Finally, the last one. 48/40 = 1.2

Because all of them are 1.2, the answer is proportional

PROPORTIONAL

The base of a triangle is eleven feet less than
Tpy6a [65]

Answer: 129 Feet

Step-by-step explanation:

You can make an equation where Height=h, and Base=b. So going backwards with the first question, the base will equal 4 times the height: b=4h, and 11 less. b=4h-11. The the other equation will be just that the base plus the height is 49. b+h=49. Then you put that into y=mx+b form. The first equation already is, and the second equation would be b=49-h. So, since the equations equal the same things, you throw away the b. Then you make a new equation by having 4h-11 equal 49-h. Since this is true seeing as they are the same triangle. Then you just use propreties of equality for the equation. You end up with 5h=60. The. You divide 60 by 5 to make 5h just equal h. So you get h=6. Then, like the qeuation said, the base (unknown) plus the height (6) is 49. So to get from 6 to 49, the answer is 43. The formula for that area of a triangle is (base x height) /2 = area. So 43 times 6 is 258. Then divided by 2 is 129. So the area of the triangle is 129.
