Answer:
See below.
Step-by-step ,explanation:
2^13 – 2^10 – 2^9
Take out the GCF, 2^9 :
= 2^9 (2^4 - 2 - 1)
= 2^9(16 - 3)
= 13 * 2^9.
So it must be divisible by 13.
Answer:
x = 131,25 m
Step-by-step explanation:
Manufacture the collar of an airbag helmet takes 1,5 m of fabric
Manufacturer is going to make 250 collars
Company only has 65 % of the needed fabric
Total quantity of fabric needed is:
250 * 1,5 = 375 m
If they have 65 % that means that they need 35 % of the total quantity
then, by rule of three
375 ⇒ 100
x ?? ⇒ 35
x = ( 375 * 35)/100
x = 131,25 m
When u multiply a number by its multiplicative inverse (its reciprocal), the product will always be 1....so ur answer is C
