Answer:
20 ft
Step-by-step explanation:
The formula for the surface area of a pyramid is often written in terms of the base dimensions and the slant height. We can solve that formula for the slant height.
SA = base area + lateral area
SA = b² + 2bs . . . . . where b is the base dimension, and s is the slant height
SA -b² = 2bs . . . . . subtract the base area
s = (SA -b²)/(2b) . . . . divide by the coefficient of s
Using the given values for surface area and base length, we find ...
s = (896 -16²)/(2·16) = 640/32 = 20 . . . feet
The slant height of the pyramid is 20 feet.
≈ 6.9 which makes sense because the nearest number that the square root of 47 is rounded to is 7 which is 49, hope this helps!
Answer:
Step-by-step explanation:
<h2>As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So, 0.331 = (0.33 × 100)(1 × 100) = 33100.</h2>
H2 + Cl2 => 2HCl
I would first list all the # of atoms of each molecule on the reactant side
(Remember that numbers on the right side of each element are the # of atoms in each unit particle).
H = 2
Cl = 2
Next, you want to match the number of atoms on the product. (Remember that the number on the left side of the unit particle shows the number of molecules of each unit particle. Also, the number applies to all the elements of the unit particle.
2HCl
Answer: 45 i think
Step-by-step explanation: cause if you divide it it is 45 sorry if im wrong
