You know the missing side of the bottom base is 6 because of the 30 60 90 special right triangle. The height is 6sqrt3 because of what i said above too, The area of a trapezoid is 1/2 b1+b2*h so 30+36*6sqrt3 is 396sqrt3 divided by 2 is 298sqrt3
Using substitution method
from the first equ
2x+y=-1
y= -1-2x --------(3)
put equ 3 into equ 2
3x -1-2x=6
3x-2x=6+1
x =7
put x+7 into equ 1
2(7) + y = -1
14 + Y =-1
y= -1-14
y=-15
so
x=7 and y=-15<span />
<u>Let's take this problem step-by-step</u>:
<u>Let's take the case of the tennis ball first</u>:
⇒ the diameter of the balls are 2.7inches
⇒ therefore they are spheres with diameters of 2.7 inches
⇒ <em>for an x-ray</em> <u>they are circles with a diameter of 2.7in</u>
<u>Now for the cylinder container</u>:
⇒ It has a width of 2.7inches
⇒ Its height:
⇒ is three balls stacked together
⇒ Height is 3 * 2.7in = 5.4 inches
⇒ <u>Overall dimension: A rectangle that is 2.7 in x 8.1 in</u>
<u />
<u />
<u>Answer:</u>
- <u>A circle with a diameter of 2.7 in</u>
- <u>A rectangle that is 2.7 in x 8.1 in</u>
<u></u>
Hope that helps!
