b*h/3 is the formula to find the volume (or area whichever it is) of a pyramid so it will be 16 times 30 divided by 3 which would get u to 480/3 which would then get u to 160 cm
Answer:
11.7 cm
Step-by-step explanation:
Using Pythagoras Theorem
AC² = AB² + BC²
AB = 4 cm
BC = 11 cm
AC² = 4² + 11²
AC = √4² + 11²
AC =✓137
AC = 11.704699911 cm
Approximately = 11.7 cm
Length AC = 11.7cm
Answer:
x^2+4x-32=0
(mid-term breaking---4 x 8=32)
x^2+8x-4x-32=0
x(x+8)-4(x+8)
x+8=0 or x-4=0
So x=+4 or x=-8
Step-by-step explanation:
I think it's D, - 12 indicates a loss of something /something getting less
Answer: 0.53
Step-by-step explanation:
From variation ,
y ∞ x ------------------------------------------------1
y = kx , where k is called the constants of proportionality and must be calculated first before proceeding.
substitute for the values in equation 2 ,below
y = kx -----------------------------------------------2
16 = k2.1
k = 16/2.1
Now to find the value of x, make x the subject of the formula in equation 2
x = y/k
= 4/ 16/2.1
= 4 ÷ 16/2.1
= 4 x 2.1/16
= 2.1/4
= 0.525
≅ 0.53
