The beginning balance of keyshawn's savings account for the month of september was $3900, and it remained this way for the first 11 days of the month. on september 12, keyshawn made a withdrawal of $700, so his balance changed, and it remained the same for a total of 9 days. on september 20, keyshawn made a deposit of $1500, so his balance changed again, and it remained the same for a total of 10 days to finish out the month. keyshawn's savings account has an apr of 3.65%, calculates interest daily, and pays interest at the end of the month. keyshawn wants to calculate the amount he earned in interest during the month of september. (5 points: part i – 1 point; part ii – 1 point; part iii – 1 point; part iv – 1 point; part v – 1 point)

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

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

they go with it happens or they mite give a chance?
