After raining for 3/4 of an hour, a rain gauge is 2/5 filled. If it continues to rain at that rate for 15 more minutes, what fraction of the rain gauge will be filled? To help answer this question, Diego wrote the division equation 3/4 ÷ 2/5 = ?. Explain why this equation does not represent the situation.

Number of minutes in 3/4 of an hour is :

n = 3/4 × 60 = 45 minutes.

Now, If it continues to rain at that rate for 15 more minutes :

So, time taken = 45 + 15 min = 1 hour.

Let, rain gauge is filled x fraction in 1 hour.

So,

Hence, this is the required solution.

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°

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
