I need health drink is 130% of the recommended daily allowance RDA for a certain vitamin the RDA for this vitamin is 45 MG. How many milligrams of the vitamin are in a drink pls due in 5 MINS

58.5 mg of the vitamin is in a drink.

Step-by-step explanation:

1. We know that a health drink = 130% of the daily allowance RDA for a certain vitamin "x"

2. In the RDA for a certain vitamin "x" = 45mg

3. Once put them together > 130% of 45 = (the missing) mg in the drink.

Now that we have that out of the way time to solve...

next, multiply 45 by 1.3 >> 130 of 45 >> 1.3(45) = 58.5

I hope this help you whether you still need it or not.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
