Answer:
55.4 m^3
Step-by-step explanation:
The volume of a pyramid of base area A and height h is V = (1/3)(A)(h).
Here, V = (1/3)(16.6 m)^2 * 10.1 m = 55.4 m^3
Answer:
i only know the answer for the first one, im sorry, its 30
Step-by-step explanation:
a=h b/2 if you need help with finding the area of something again use this, Geometry calculator
<span>3x = y + 7
</span><span> y =3x-7
</span>
<span>8x = 2y + 5
</span><span>8x = 2(3x-7) + 5
8x=6x-14+5
8x-6x=-9
2x=-9
x=-4.5
</span><span>8x = 2y + 5
</span>8(4.5)=2y+5
36=2y+5
2y=31
y=15.5
Answer:
y=mx+b
Step-by-step explanation:
standard slope intercept form. just plug in slope and intercept
The larger number is (-7+14)/2 = 3.5.
The smaller number is (-7-14)/2 = -10.5.
_____
The two equations a+b=-7, a-b=14 can be solved to get these results. It is genrally convenient to solve them by adding one to the other, or subtracting one from the other.
