Answer:

2,242.5

Step-by-step explanation:

10² = 100 (one and 2 zeros ; notice that the exponent is 2 )

Makes sense that we will need a bigger number than 22.425 to divide by 100 to get a 22.425 so move the decimal point to the left 2 spots and get 2,242.5.

2,242.5 /100 = 22.425

Write an expression for the area of a triangle with a height of 2x^2 units and a base of 5x^2+4x units

Stolb23 [73]

Answer:

The area of the triangle is $5x^4 + 4x^3$ square units

Step-by-step explanation:

Given

Shape: Triangle

$Height = 2x^2$

$Base = 5x^2+4x$

Required

The area of the triangle

The area of a triangle is calculated as thus;

$Area = \frac{1}{2}(base)(height)$

By substituting $Height = 2x^2$ and $Base = 5x^2+4x$ ; This gives

$Area = \frac{1}{2}(5x^2 + 4x)(2x^2)$

$Area = \frac{(5x^2 + 4x)(2x^2)}{2}$

$Area = (5x^2 + 4x)(x^2)$

Open Bracket

$Area = 5x^2 * x^2 + 4x * x^2$

$Area = 5x^4 + 4x^3$

Hence, the area of the triangle is $5x^4 + 4x^3$ square units

The box plot show the price of textbooks at a local high school. What range describe the middle 50% if the price (p) of the text

Grace [21]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the box plot is not attached.

However, the interpretation of the question is to determine the inter-quartile range (IQR) ; this represents the middle 50% of scores

To answer this question, I will make use of the attached box plot.

IQR is calculated as:

$IQR = Q_3 - Q_1$

$Q_1$ and $Q_3$ are represented by the vertical edges of the rectangle in the box plot. [See attachment]

Reading $Q_1$ and $Q_3$ , we have:

$Q_1 = 37$

$Q_3 = 50$

The IQR is:

$IQR = 50 - 37$

$IQR = 13$

<em>Hence, the range that describes the middle 50% of the attached plot is 13</em>
