Divide 2178/19=114.6 first number inside is 115
Than divide 3875/19=203.94 last number is 203
we will get multiples when subtract 203-115+1=89 multiples
Good luck!!!
A they are at 90° angles and that is the definition of being perpendicular.
2.35 + 1.10 = 3.45
2.35 / 3.45
1.10 / 3.45
294.20 / 3.45 x 1.10 = 93.80 to 4sf
294.20 / 3.45 x 2.35 = 200.40 to 4sf
93.80 + 200.40 = 294.20
93.80 / 1.10 = 85.2727272727
200.40 / 2.35 = 85.2765957447
85 + 85 = 170 need two more
84 x 1.10 = 92.40 84 x 2.35 = 197.4
88 x 2.35 = 206.8 88 x 1.10 = 96.8
= 299.2 = <u>294.20</u>
Answer: 84 sundaes and 88 ice cream cones were sold.
I guess I spent too long and the working out was probably more long-winded than it should've been.
"Regular quadrilateral" means it has four sides, and the
sides AND the inside angles are all equal.
-- The one at the upper left is a rhombus. All 4 of its sides
are the same length, and the first time I saw it, I picked it.
But then I remembered that in order to be 'regular', the
inside angles also have to be equal, and in a rhombus,
they're not.
-- The one in the lower right is a square. It has four sides,
they're all equal, and the inside angles are all the same too.
So the square is the only one that does the job for you.
