5A Charlotte buys two biscuits and a carton of milk for $5.00.

Oliver buys three biscuits and a carton of milk for $6.50.

27 ÷ N has a remainder of 3.

How different positive integers could N be?

5C

Some identical cubes are arranged in a pyramid-like form with 5 layers. Starting from the bottom layer, the number of cubes in the layers are 5 x 5, then 4 x 4, then 3 x 3, then 2 x 2, then 1 x 1. The whole exterior of the pyramid is painted including the bottom. How many of the cubes will have none of their faces painted?

Chloe notices that 91 = 100 - 9 = (10 + 3) x (10 - 3) = 13 x 7.

Since 7 and 13 are primes, 91 has two prime factors.

Mia notices that 391 = 400 - 9 = (20 + 3) x (20 - 3) = 23 x 17.

Since 17 and 23 are primes, 391 has two prime factors.

Using the same method, Ruby finds prime factors of 1591.

Find the sum of Ruby's prime factors.

There are 5 different coloured cups in a row.

The green cup is to the left of the red cup (but not necessarily next to it).
The yellow cup is to the left of the purple cup (but not necessarily next to it).
The blue cups is on one end of the row of cups.
For all these 3 statements to be true, how many different ways could these 5 cups be arranged?

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
