Answer:
x√5 = x square root 5
Step-by-step explanation:
√35x^5 ÷ √7x^3 = √(35x^5 / 7x^3)
√(35x^5 / 7x^3) = √(5x^5 / x^3)
√(5x^5 / x^3) = √5x^(5-3) = √5x²
√5x² = x√5
The equation that models the situation is 15x + 9y = 450
The x-intercept is (30, 0) and the y-intercept is (0, 50)
Given the following parameters:
- Cost of concert tickets for general admission= $15
- Cost of a ticket for those with student ID = $9
Given that the total sales is $450, the equation that models this situation will be expressed as:
where:
x is the those that admitted generally
y are those with student ID
<u />
<u>Get the x-intercept.</u>
This is a point where the y-axis is zero
15x + 9y = 450
15x + 9(0) = 450
15x = 450
x = 450/15
x = 30
Thee x-intercept is (30, 0)
<u>Get the y-intercept.</u>
This is a point where the x-axis is zero
15(0) + 9y = 450
0 + 9y = 450
9y = 450
y = 450/9
x = 50
The y-intercept is (0, 50)

Answer:
280 ft squared
Step-by-step explanation:
To find the area of the nonshaded portion, we can find the area of the entire floor and then subtract the shaded area.
The total area is that of a rectangle: 30 * 15 = 450 ft squared.
Now, the shaded region is made up of a rectangle and a triangle.
- The rectangle has length 8 and width 10, so its area is 10 * 8 = 80 ft squared.
- The triangle has base 12 and height 15, so using the area of a triangle formula: 
(where b is the base and h is the height) = (12 * 15)/2 = 180/2 = 90 ft squared.
- The total shaded region is: 80 + 90 = 170 ft squared
Subtract 110 from 450: 450 - 170 = 280 ft squared.
Thus, the answer is 280 ft squared.
