Answer: B
Step-by-step explanation:
Let's work this problem backwards. So, if he has y dollars left after spending 25% the second time or 3/4 of the money left. So, inverse it to get 
y. Then, do the same for 20% or 4/5, then 4/3y * 5/4 = 5/3y
The slope is 2.
Reason: you find the slope by dividing the difference of the y-coordinates (5 and 9) by the difference of the x coordinates (1 and 3)
9-5=4
3-1=2
4 divided by 2 =2
We can use inverse sin to calculate the angle, and we get around 56 degrees (but for the answer I'll give the most accurate one). For cos we get around 55, and for tan we get .25.
I might have done tan wrong but I hope you get the point.
Answer:
4
Step-by-step explanation:
Whichever number appears the most in the list of numbers which in this is 4
The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps
