Answer:

IF ABC and DEF are complementary then ABC + DEF = 90°

Therefore, DEF = 90° -ABC

Since DEF = 54° and DEF = x then

x = 90° -54°

x = 36°

Sally has 2 cats and each cat eats 1/4 of a tin of cat food each day.
Mashutka [201]

If one cat eats 1/4 of a tin per day then two cats eat 1/2 of a tin per day.

We have 9 tins so if each day cats eat 1/2 we have to divide 9 with 1/2 and we get 18 which is for how many days she can feed the cats until she runs out of food.

Hope this helps.

TEA [102]

Answer:

For 9 the answer is (4)

For 11  the answer is (5)

For 14 the answer is (4)

I cant see number 16 so maybe retake the photo thanks!

Step-by-step explanation:

9. squares have two sets of parallel lines

11. The only quadrilateral that has 3 different side lengths on this list is a trapezoid

14. It has no right angles meaning its not a square or rectangle. It has two sets of parallel sides meaning its not a trapezoid, and since it gives two different side lengths its not a rhombus since all sides muse be congruent to be a rhombus. The only one that matches is 4 a parallelogram
