Write a first step question and answer. then solve the problem. jerome bought 8 packs of baseball cards at a garage sale. each pack has 10 cards. he gave his younger sister 3 cards from each pack. how many cards does jerome have left?

Jerome has left 56 cards.

Explanation:

Since we have given that

Number of packs of baseball cards at a garage sale = 8

Number of cards in each pack = 10

Total number of cards in all is given by

Now,

He gave his younger sister 3 cards from each pack ,

So,

Number of cards he gave to his younger sister from each pack = 3

Number of packs were there = 8

So,

Total number of cards he has given to his younger sister is given by

So, number of cards left to Jerome is given by

So, there are 56 cards Jerome left with .

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

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°
