Kyle's math teacher is basing quarterly grades on different percentages for the various work shown on the table. Using the given
scores, what is Kyle's expected quarterly average? Round to the nearest whole percent.

Step-by-step explanation:

Kyle's quaterly scores of various grade works are shown in the table.

To find the quaterly average of Kyle, we have to take average on the scores listed in the table.

Here, 4 subjects are listed and average must be performed on those scores.

Average = = 86.5 % = 87%

Kyle's expected quaterly avaarage = 87%

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

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°
