Answer:

58.5mg of the vitamin in a drink

Step-by-step explanation:

We know...

130% of RDA for vitamin x >> RDA for vitamin x = 45mg >> 130% of 45 = ?? mg in a drink.

1. 130% = \frac{130}{100} = 1.3

2. 130% of 45 >> 1.3(45)=58.5

I hope this helps you?!

28) Find the circumference of a circle with a diameter of 2.5 inches. (it = 3.14)
antoniya [11.8K]

Answer: Circumference = 7.85 inches

Concept:

Here, we need to know the idea of circumference.

The circumference is the perimeter of a circle. The perimeter is the curve length around any closed figure.

Circumference = 2πr

r = radius

π = constant

Solve:

<u>Given information</u>

r = (1/2) d = (1/2) (2.5) = 1.25 inches

π = 3.14

<u>Given formula</u>

Circumference = 2πr

<u>Substitute values into the formula</u>

Circumference = 2 · (3.14) · (1.25)

<u>Simplify by multiplication</u>

Circumference = (2.5) · (2.14)

Circumference = \boxed {7.85 inches}

Hope this helps!! :)
