96 people are attending the concert.
Step-by-step explanation:
Given,
Number of children at concert = 12
This represents 12.5% of the people attending concert.
Let,
p be the total people attending concert.
12.5% of p = 12

Dividing both sides by 0.125

96 people are attending the concert.

Answer:
3 grams
Step-by-step explanation:
We are going to take the mass of a bunch of little strips below the triangle "roof." To do this, we must figure out what formula for the mass we'll use, in this case, we'll use:
Mass of strip = denisty * area = (1+x)*y*deltax grams
now, because the "roof" of the triangle contains two different integrals (it completely changes direction), we will use TWO integrals!
**pretend ∈ is the sum symbol
Mass of left part = lim x->0 ∈ (1+x)*y*deltax = inegral -1 to 0 of (1+x)*3*(x+1) = 3 * integral -1 to 0 of (x^2 + 2x + 1) = 3 * 1/3 = 1
Mass of left part = lim x->0 ∈ (1+x)*y*deltax = inegral 0 to 1 of (1+x)*3*(-x+1) = 3 * integral 0 to 1 of (-x^2 + 1) = 3 * 2/3 = 2
Total mass = mass left + mass right = 1 + 2 = 3 grams
Answer:
2 1 ÷ 2
Step-by-step explanation:
Given that
The kitchen of Amita would be a rectangular area contains 3 and 3 ÷ 4 square meters
And, the width of her kitchen is 1 and 1 ÷ 2 meter
So based on the above information, the length of Amita kitchen is
Here you divide the rectangular area by the width
= (3 and 3 ÷ 4) ÷ (1 and 1 ÷ 2)
= 2 and 1 ÷ 2
Hence, the length in meters of Anita's kitchen is 2 and 1 ÷ 2
