Ginger adds 15 ml of vitamin c drops to her guinea pig's water everyday. a bottle
of vitamin c drops holds 350ml and costs $4.85. about how much does she spend
on vitamin c drops each year?
a- $70 to $90
b- $50 to $70
c- more than $90
d- less than $50

A

Step-by-step explanation:

First find how many bottles Ginger will need.

15 mL x 365 day = 5475 mL for 1 yr

5475 mL / 350mL = 16 bottles

Then find the price for the 16 bottles.

16 bottles x $4.85 = $77.60

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
