Answer:
((4x3)/2)2 + (5x10) + (10x4) + (10x3) = 132 cm^2
Step-by-step explanation:
find area of triangles then of the other rectangular faces and add them.
Answer:
m = -3/4
Step-by-step explanation:
Take any two points on a line to find the slope. Here they give you the points
(0, 5) and (4, 2).
Put these points into the slope formula.
y₂ - y₁/x₂ - x₁
2 - 5/4 - 0
-3/4
The slope of this line is -3/4.
The surface area (SA) of a cube can be written as:
SA = 6s²
From here we can write, the length of the side s as:
For cube with surface area of 1200 square inches, the side length will be:
inches
For cube with surface area 768 square inches, the side length will be:
inches
The difference in side lengths of two cubes will be:
Rounding to nearest tenth of an integer, the difference between the side lengths of two cubes will be 2.8 inches.
In a given radioactive nuclide, we can easily find the mass number, mass of proton and neutron by subtracting the mass of proton from the mass number. The mass number, mass of proton and mass of neutron of the radioactive nuclide are 131, 56 and 75 respectively.
<h3>Properties of an atom</h3>
Data;
- Mass Number = 131
- Atomic Number = 56
In a given atom, the mass number of an atom comprises of the mass of proton and mass of neutron. The atomic number of the element or atom is equal to the mass of the proton.
In this case,
mass number = mass of proton + mass of neutron.
From the calculation above, the mass number, mass of proton and mass of neutron of the radioactive nuclide are 131, 56 and 75 respectively.
