Depth: 7/2 feet
Rate: 5/4 feet per hour
Time = depth / rate of filling
Time = 7/2 / 5/4
Time = 14/5
Time = 2 4/5 hours
I'm attaching the solution.. feel free to ask if you have questions.. I basically did long division. Hope this helps.
Answer:
Step-by-step explanation:
There are two consecutive positive even integers such that the square of the first is 364 more than five times a second. What are the two numbers?
Two consecutive year positive integers are represented by
x and x + 1
First integer = x
Second integer = y
There are two consecutive positive even integers such that the square of the first is 364 more than five times a second.
This is represented mathematically as:
x² = 364 + 5(x + 1)
x² = 364 + 5x + 5
x² -5x -5 - 364
x² - 5x - 369
I believe the answer would be B

Answer:</h2>
<u>The correct option is 3x + 4y = 10</u>
<h2>
Step-by-step explanation:</h2>
The standard form for any linear equations having two variables is written as Ax+By=C. For example, 3x+4y=10 is a linear equation in standard form. When an equation is given in this form, it becomes easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations whose solution is required to find the point of intersection of given lines.
