We know that there are 15 children altogether
We know that the number that voted for B+R is double the number of students voted for G+Y
B+R = 2(G+Y)
Think of two numbers that add up to 15, one number is twice of the other number.
For example, 6 and 12.
12 is double of 6 but 6 + 12 doesn't give 15
So, think again
for example 5 and 10
10 is double of 5 and 5+10 does give 15
So, the number that voted Red and Blue is 10 and the number that voted Yellow and Green is 5
Given:
A square base pyramid whose base length is 10 in. and height of triangular surface is 4 in.
To find:
The surface area of the pyramid to the nearest whole number.
Solution:
A square base pyramid contains square base with edge 10 in. and 4 congruent triangles with base 10 in. and height 4 in.
Area of a square is
So, area of square base is 100 sq. in.
Area of a triangle is
So, area of each triangular surface is 20 sq. in.
Now, the total surface area of the pyramid is
Total area = Area of square base + Area of 4 congruent triangles.
Therefore, the area of the pyramid is 180 sq. in.
Answer:
The answer is s=-1 or s=-12
Step-by-step explanation:
First Step: Factor left side of equation.
(s+1)(s+12)=0
Second Step: Set factors equal to 0.
s+1=0 or s+12=0
So, the answer is either -1 or -12
