Answer: 3.79 litres
Step-by-step explanation:
1 litre is equivalent to about 1.05668821 American quarts.
4 quarts would therefore be;
= 4/1.05668821
= 3.78541178
= 3.79 litres
Answer:
All are True
a) 30a^6-24a^2=3à^2(10a^4-8)
b) 24a^4+18=6(4a^⁴+3)
c) 16a^5-20a^3=4a^3(4a^2-5)
D) 12a^3+8a=4(3a^3+2a)
Step-by-step explanation:
a) 30a^6-24a^2=3à^2(10a^4-8)
since; 3à^2(10a^4-8)
= 30a^6 - 24a^2
b) 24a^4+18=6(4a^⁴+3)
Since; 6(4a^⁴+3) opening the brackets
= 24a^4 + 18
c) 16a^5-20a^3=4a^3(4a^2-5)
Since; 4a^3(4a^2-5)
, opening the brackets we get
= 16a^5 - 20^3
D) 12a^3+8a=4(3a^3+2a)
Since;4(3a^3+2a), opening the bracket we get;
= 12a^3 + 8a
Answer:
41 1/4 and 15
Step-by-step explanation:
So for the first question, we know that a single inch of thread has 16 1/2 bolts. We know that there are 2 1/2 inches of thread.
To find the total anount of bolts in the thread, we can multiply 2 1/2 by 16 1/2:
2 1/1*16 1/2 = 41 1/4
That is our first answer.
For our next answer, we know that a book is 1 7/8 inches big.
The bookshelf is 28 1/8 inches big.
To find how many of the 1 7/8 inch big books can fit in the 28 1/8 inch big bookshelf, we can divide 28 1/8 by 1 7/8:
28 1/8/1 7/8
=
15
So our 2nd answer is 15.
Hope this helps!
