Lisa invests $4,000 in two types of bonds, bond a and bond b. bond a offers a 10% return, and bond b offers a 6% return. lisa invests $x in bond a and $y in bond b. her total return on the investment is $340. the system of linear equations defining the situation iswhat . the amount lisa invested at the rate of 10% is what , and the amount she invested at the rate of 6% is what

Lisa invests $4,000 in two types of bonds, bond A and bond B. Bond A offers a 10% return, and bond B offers a 6% return. Lisa invested in each bond in x and y amounts. To solve the problem using two equation: x +y =4000

                0.10x + 0.06y = 340

Solving the equation lisa invested $2500 in 10% rate and $1500 in 6% rate.

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°
