Answer:
{x | x<5/4}
Step-by-step explanation:
Add 2 to both sides and simplify:
4x<5
Divide both sides by 4 and simplify:
x<5/4
Answer:
240 m³
Explanation:
The volume of a pyramid is equal to:
Where B is the area of the base and H is the height of the pyramid.
Then, the base of the pyramid is a triangle, so the area of a triangle is equal to:
Where b is the base of the triangle and h is the height of the triangle. So, replacing b by 16 m and h by 9 m, we get:
Finally, replacing B by 72 m² and H by 10 m, we get that the volume of the pyramid is equal to:
Therefore, the volume is 240 m³
Answer:
18 + 5 = 23
Step-by-step explanation:
Answer:
Given a square ABCD and an equilateral triangle DPC and given a chart with which Jim is using to prove that triangle APD is congruent to triangle BPC.
From the chart, it can be seen that Jim proved that two corresponding sides of both triangles are congruent and that the angle between those two sides for both triangles are also congruent.
Therefore, the justification to complete Jim's proof is "SAS postulate"
Step-by-step explanation:
It's the one on the bottom left that says 5ft and 3ft, they're the same shape and ratio just turned around. It's also the square that says 6ft and 10ft because its only two times bigger than the original and has similar proportions.
