Answer:
10. x= 10 y=sqrt 200
11. x=y=450
12. x=19 y=sqrt 1083
13. x=sqrt 48 y=sqrt 12
Step-by-step explanation:
10.
x and 10 are the same
10^2+10^2=200
sqrt 200 is not a whole number so y is just sqrt 200
11.
30^2=2x^2 because x and y are the same
x^2=450
sqrt 450 is not a whole number so x and y are just sqrt 450
12.
x= 38 divided by 2=19
38^2=19^2+y^2
1444=361+y^2
y^2=1083
sqrt 1083 is not a whole number so y is just sqrt 1083
13.
x^2=(x/2)^2+36=x^2/4+36
x^2=48
sqrt 48 is not a whole number so x is just sqrt 48
y is half of x so it is sqrt 12
I would be 3x i think.......
Answer:
9.) 6.5 ft
10.) 36 ft²
11.) 770 cm²
12.) 10,087 cm³
Step-by-step explanation:
9.) Find the height:
V = lwh
234 = 8(4.5)h
234 = 36h
/36 /36
6.5 = h
10.) Area of base:
B = lw
B = 8(4.5)
B = 36
11.) Area of the base:
B = lw
B = 35(22)
B = 770
12.) Volume of the pyramid:
V = Bh/3
V = 770(39.3)/3
V = 30,261/3
V = 10,087
