Answer: x = 20, y = -15
Step-by-step explanation:
Since we already know that , we can just substitute in that value of y into the other equation:
with the value of x, we can find the value of y:
Area of the triangle at the top=1/2basexheight
1/2x10x 2= 10
Area of rectangle =length xwidth
9x10=90
Total area =area of triangle +area of rectangle
90+10=100m^2
Answer:
pretty sure it's A
Step-by-step explanation:
cuz a common factor of 9 and 10 is 90 do the calculations and it should be simple.
Answer:
SA = 680 units^2
V =1200 unit^3
Step-by-step explanation:
If the radius is 5 then the diameter is 2r = 2*5 = 10
The height would remain the same
Surface area of a prism is given by
SA = 2 (lw+lh+hw)
l =d = 10 w = d = 10 h = 12
SA = 2 ( 10*10 + 10 * 12+ 12* 10)
SA = 2( 100+120+120)
SA = 2(340)
SA = 680 units^2
V = l*w*h = 10*10*12 =1200 unit^3
Answer:
no
Step-by-step explanation:
1 2/6 could be simplified as 1 1/3
1 3/6 could be simplified as 1 1/2
using logic they are not equivalent
you could also do cross multiplication with 4/3 and 3/2
since 8 does not equal 9, the two fractions are not equal
