Answer:
0
3
10
21
36
Explination:
0 x anything is still zero, but I don't know if that counts.
1 (2+1) = 3
2 (4+1) = 10
3 (6+1) = 21
4 (8+1) = 36
Answer:
the answer is 7 units
Step-by-step explanation:
Answer:
<u>135 cubes</u>
Step-by-step explanation:
Volume of cuboid :
- 45 x 16 x 12
- 720 x 12
- 8,640 cm³
Volume of a small cube :
Number of cubes :
- n = 8,640/64
- n = <u>135 cubes</u>
a. 9/10
explanation:
• the denominators (bottom number) are the same so there is no need to change to a common factor
• because the fractions have common factors, you add the top numbers (3+6) to get 9
• then you put the top number over the 10 (9/10) and it’s simplified as much as possible
b. 3/4
explanation:
• each denominator (bottom term) is a factor of 12 so you have to change each fraction to #/12
• to change 1/3, you multiply the top and bottom numbers by 4 (1x4 & 3x4 = 4/12)
• to change 1/4, you multiply the top and bottom numbers by 3 (1x3 & 4x3 = 3/12)
• to change 1/6, you multiple the top and bottom numbers by 2 (1x2 & 6x2 = 2/12)
• then you add each of the top numbers (4+3+2) and put it over the common denominator (12) to get 9/12
- both 9 & 12 are divisible by 3, so you simply by dividing both by 3 to get 3/4
c. 1/3
explanation:
•the denominators are the same, so you subtract 5-3 without changing the denominator & you get 2/6
• then, because both numbers are divisible by 2, you divide both by 2 and get 1/3
20 less than (-20) a number (n) is more than (>) twice the same number (2n)
-20+n>2n
minus n both sides
-20>n
n<-20
