I only know (b) and 28 (c)
(b) Multiples of 120= 120,240,360,480,600
Multiples of 150= 150,300,450,600
Both numbers have 600 as their first common multiple so the ANSWER is 600
28. (a) Common factors of 24= 1,2,3,4,6,8,12,24
Common factors of 64= 1,2,4,8,16,32,64
8 is the only common factor for both 24 and 64 so 8 is the ANSWER
3/4, x, and y that is the answer
Answer:



Step-by-step explanation:
Given
<em>Decimal Grid = Hundredths</em>



To solve for each:
We have:
For Amber:


For Grace:




This means that Grace shaded 60 of the hundredth models.
Decimal shaded is:



For Marsha:




Multiply this by 100, to get the number of shaded


This means that Marsha shaded 170 of the hundredth models.
Decimal shaded is:


Answer:
9
Step-by-step explanation:
Special right triangle
this is a 45, 45, 90 triangle
Meaning that whatever the hypotenuse is
that it will be the same for x
Answer:
tge area of triangle is 36 in2 so she can only create 4 triangle
Step-by-step explanation:
area of square grid = 12 × 12
=144
area of triangle = 1/2 × 6 × 6
;;; = 18 ×2
=36
area if square grid/ area of triangle
=144/ 36
=4
