Answer:

60 -047 = 13 in²

Step-by-step explanation:

Paper area: 6 x 10 = 60

15 circles, each circle has diameter: 6 /3 or 10 /5 = 2

each circle area: πr² = 3.14 x 1² = 3.14

15 circles: 3.14 x 15 = 47.1

paper wasted: 60 - 47.1 ≈ 13 in²

A triangle with constant base b and height h is changing with time where h(t)=3t +1. What is the rate of change of the area of t

Keith_Richards [23]

The rate of change of the area of the triangle when t=1 is also equal to 3.

<h3>Rate of change</h3>

Given the function of height of a triangle expressed as:

h(t) = 3t + 1

The rate of change is expressed as

dh/dt = 3

The rate of change of the area of the triangle when t=1 is also equal to 3.

Answer:

Javier's parents set aside $1500 when he was born

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this question, we have that:

$E = 1012.50, t = 15, I = 0.045$

We have to find P. So

$E = P*I*t$

$1012.50 = P*15*0.045$

$P = \frac{1012.50}{15*0.045}$

$P = 1500$
