The answer must be
since the triangular pyramid has 4 faces and each has an area of 30
we should multiply that by 4 , so :
Answer:
54 Pounds
Step-by-step explanation:
We know that they start off with 67.5 pounds of sugar and they need to reduce it by 20%. We also know from the problem that we want to know the MAXIMUM amount of sugar consumed by each track member.
The typical high school student consumes about 67.5 pounds of sugar per year. That is our first piece of the problem
67.5
We now know that 20% of it needs to be reduced. This means that we can multiply it by 0.8 because that is 20% less than 100% of the sugar.
67.5 x 0.8
This leads the answer to be 54 Pounds
Hope this helped :D
Answer:
Step-by-step explanation:
Sum of the angles of a triangle is ALWAYS 180°.
2x+3x+5x = 180°
10x = 180°
x = 18°
2x = 36°
3x = 54°
5x = 90°
The angles are 36°, 54°, and 90°
Answer:
Option B
Step-by-step explanation:
<WXV = <YXZ (Vertically opposite angles are congruent.)
Given:
A sum of money is divided between A,B and C in the ratio 9:8:7.
Total sum is 480.
To find:
The part of money A get.
Solution:
Let A, B and C get 9x, 8x and 7x respectively.
Total sum is 480.
Divide both sides by 24.
Now,
Therefore, amount received by A is 180.
