It takes 1.5 m of fabric to make the collar of an airbag helmet. the manufacturer is making 250 special-order collars. one morning, a technician finds they have only 65% of the fabric they need to make the collars. how many more meters of fabric is needed to be able to make all 250 collars?

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

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

dont trust me im no expert these losers made me fail a test bro this sucks
