The approximate area of the triangular base of James’ tank is 3025 in²
To find the approximate area of the triangular base of James' tank, we need to know what scale is.
<h3>What is scale?</h3>
A scale is the ratio of two dimension. It is given by scale = New dimension/old dimension
Given that the dimensions of James’ tank are each exactly 2 3/4 times the dimensions of Julian’s tank.
The scale of the area of James' tank to the area of triangular base of Julian's tank is S = (2³/₄)²
= (11/4)²
= 121/16
Let
- A = area of triangular base of James' tank,
- A' = area of triangular base of Julian's tank = 400 in²
So, scale, S = A/A'
<h3>
The approximate area of the triangular base of James’ tank</h3>
So, making A subject of the formula, we have
A = SA'
A = 121/16 × 400 in²
A = 121 × 25 in²
A = 3025 in²
So, the approximate area of the triangular base of James’ tank is 3025 in²

Step-by-step explanation:
The population of the state of California was about 37,250,000 people in 2013. Which number best approximates the population as a single digit times a power of 10?
A. 3 × 10⁻⁶
B. 4 × 10⁻⁷
C. 3 × 10⁶
D. 4 × 10⁷
Answer:
Option D = 4 × 10⁷
Step-by-step explanation:
We are given the population of people = 37,250,000 people
We round to a power of 10
and that would give us 3.7 × 10⁷
We are told in the question to approximate the population as a single digit,
3.7 × 10⁷ s a single digit = rounding up to the nearest whole number
= 4 × 10⁷.
Therefore, the number that best approximates the population as a single digit times a power of 10 is
= 4 × 10⁷
