Answer:
225
Step-by-step explanation:
Using the basic components of summation ∑
∑n = 
n(n + 1) and ∑1 = n
Thus
∑ (2n - 1) ← for n = 1 to 15
= ∑2n - ∑1
= 2∑n - ∑1
= 2 ( n(n + 1)) - n
= n(n + 1) - n ← Evaluate for n = 15 ( the upper value )
= 15 × 16 - 15
= 240 - 15
= 225

Answer:
$1875
Step-by-step explanation:
Given the information:
- An apartment costs: $625 per month
- They require that the cost of rent be no greater that a third of his monthly income
- The must earn at least 3 times the cost of his rent
=> the smallest amount of money that Carlos needs to make per month to be approved to move in:
= 3 times of $625
= 3*$625
= $1875
because 625 is exactly 1/3 of $1875
Hope it will find you well.
Answer:
lateral surface area = 48 inches²
Step-by-step explanation:
The picture below is the square base pyramid you are referring. The lateral area is adding the area of the 4 triangles in the pyramid.
area of a triangle = 1/2 × b × h
The slant height of the triangle is gotten using Pythagoras theorem
lateral surface area = 4 × (1/2 × 3 × 8)
lateral surface area = 4 × 24/2
lateral surface area = 4 × 12
lateral surface area = 48 inches²
