Mathematics
1 answer:
zalisa [80]3 years ago
4 0

Answer:

A=128\ cm^2

Step-by-step explanation:

we know that

The area of the polygon is equal to the area of a square plus the area of four congruent triangles

so

A=b^2+4[\frac{1}{2}(b)(h)]

where

b=8\ cm\\h=4\ cm

substitute

A=8^2+4[\frac{1}{2}(8)(4)]

A=64+64=128\ cm^2

I have 6 eggs, I broke 2 eggs, fried 2 eggs, and ate 2 eggs. How many eggs do I have left.
ohaa [14]

Answer:

4 eggs are left.

Step-by-step explanation:

It is actually a tricky question and the trick is that the person, who initially have 6 eggs, has broken two eggs out of them.

Those two broken eggs were then fried and later he ate those.

It is a single incident but in question it appears that 3 different incidents took place in which the person have used all 6.

So actually, he only ate 2 eggs out of 6.

Marta wrote six and eighty hundredths. Nicky wrote six and eight tenths. Who wrote the greater number? explain
nataly862011 [7]
The numbers are both equal because, 6.80 is six and eight hundredths, and 6.8 is six and eight tenths. When writing decimals any zero added to the end of the number has no value, 8/10 as a fraction is equal to 80/100 if simplified, so Nicky and Marta wrote equal numbers. :)
