Answer:
The effect of doubling all the dimensions of a triangular pyramid will have on the volume of the pyramid is to increase it by 8 times.
Step-by-step explanation:
i) volume of triangular pyramid =
Area
height
=
(Base of triangle
perpendicular height of triangle)
height
ii) if we double all the dimensions then the three variables((Base of triangle, perpendicular height of triangle, height of pyramid) will be doubled
and the volume of the new pyramid will be 8 times that of the original one.
Answer:
9/4 yards
Step-by-step explanation:
A poster is a rectangle.
Area of rectangle = Length × Width
Given:
Area = 3/4 yd
Length = 1/3 yd
Substitute the given values to the equation.
3/4 = 1/3 × w
3/4 = 1/3w
3/4 ÷ 1/3 = w
3/4 × 3/1 = w
9/4 = w
So take 13, 8 and 4 and add those together to get the budget she needs for the month.
13+8+4=25
so she needs $25 in all, to find how much more than 16 she needs you take 25 and minus 16 from it.
25-16=19
so she needs $19 more to have a balanced budget.
Answer:
Step-by-step explanation:
So the first thing to do is get the number of angles inside this pentagon, which is 540 degrees. One way to do this is that you know a pentagon is formed of 3 triangles and since there are 180 degrees in a triangle, 3x180=540
Then it is algebra
540=91+125+92+(3x-5)+(4x-8)
Simplify what you can and collect like terms
540=308+3x-5+4x-8
540=308+7x-13
Then move everything over to the one side so that the variable is isolated
540-308+13=7x
245=7x
242/7=x
35=x
