Find the value of x so the rectangles have the same area

1 answer:

Area of rectangles = width * length.
So x*12 = 12x = area of first rectangle
So 16*(x-2) = 16x -32 = area of second rectangle

The question states to make them equal, so:
first rectangle = second rectangle
12x = 16x -32
Solve for x
-4x = -32
4x = 32
x = 8

The price of Stock A at 9 A.M. was $14.15. Since then, the price has been increasing at the rate of $0.06 each hour. At noon

Marina86 [1]

Answer:

<h2>2 hours</h2>

Step-by-step explanation:

Easiest way to solve this is add and subtract till we get the values balanced.

Stock A

9 am $14.15

10 am $14.21

11 am $14.27

12 pm $14.33

1 pm $14.39

2 pm $14.45

Stock B

12 pm $14.65

1 pm $14.57

2 pm $14.45

Notice the bold values are the same at the same time 2 pm. If we start at 12 pm with stock B, it will be 2 hours before the prices are the same.

I'm always happy to help :)

wind resistance varies jointly as an objects surface area and velocity. if an object traveling at 55 miles per hour with a surfa

nikdorinn [45]

Answer:

25 miles per hour

Step-by-step explanation:

Given

$W = Wind\ resistance$

$A = Surface\ Area$

$V = Velocity$

The joint variation can be represented as:

$W\ \alpha\ A*V$

Where:

$V = 55; A = 20; W = 220$

Required

Find V, when: $A = 55; W = 275$

We have:

$W\ \alpha\ A*V$

Express as an equation

$W= k *A*V$

Where k is the constant of variation

Make k the subject

$k = \frac{W}{A*V}$

When: $V = 55; A = 20; W = 220$

We have:

$k = \frac{220}{20 *55 }$

$k = \frac{220}{1100}$

$k = 0.2$

When: $A = 55; W = 275$

We have:

$k = \frac{W}{A*V}$

Substitute: $A = 55; W = 275$ and $k = 0.2$

$0.2 = \frac{275}{55 * V}$

Make V the subject

$V= \frac{275}{55 * 0.2}$

$V= \frac{275}{11}$

$V= 25$
