This is probably not right, but Im gonna try my best and I feel you. I could possibly be because of pressure but I dont know. I REALLY hope thats right, its my best guess.sorry
The picture in the attached figure
the question is
What is the surface area of the ramp?
we know that
surface area=2*[(36+12)*5/2]+2*[15*13]+[12*15]+[36*15]
surface area=240+390+180+540
surface area=1350 in²
the answer is1350 in²

Answer:
Choosing a boy randomly in a class of 10 boys and 10 girls
Step-by-step explanation:
The probability of choosing a boy randomly in a class of 10 boys and 10 girls is calculated as;
(number of boys)/ (total number of students in the class)
= 10/(10+10) = 10/20 = 1/2
The probability of drawing a heart randomly out of a pile of 4 hearts and 8 spades is calculated as;
4/(4+8) = 4/12 = 1/3
The probability of correctly choosing a random number between 1 and 10 is simply 1/10 since the numbers are have a uniform distribution and thus equally likely to be selected.
The probability of choosing a girl randomly in a class of 8 girls and 12 boys is calculated as;
(number of girls)/ (total number of students in the class)
= 8/20 = 2/5
Thus choosing a boy randomly in a class of 10 boys and 10 girls is the event which has a probability closest to 1.
