To find area you multiply length times width because you have a 3cm square the length is 3cm and the width is 3cm so 3 x 3 = 9 so the area is 9cm²

Darcy harvest 8 3/4 acres of corn every 5/6 of an hour. How many acres per hour?

otez555 [7]

Answer:

The answer is $10\frac{1}{2}\ per\ hour.$

Step-by-step explanation:

Given:

Darcy harvest 8 3/4 acres of corn every 5/6 of an hour.

Now, to find the acres per hour it takes to harvest.

Darcy harvest = $8\frac{3}{4}=\frac{35}{4}\ acres.$

The time he took to harvest = $\frac{5}{6}\ hour.$

So, to get the acres per hour we put formula:

$Distance = \frac{35}{4}\ acres.$

$Time=\frac{5}{6}\ hour.$

$Speed=\frac{distance}{time}$

$Speed=\frac{\frac{35}{4}}{\frac{5}{6}}$

$Speed=\frac{35}{4}\times \frac{6}{5}$

$Speed=\frac{210}{20}$

$Speed=\frac{21}{2}$

$Speed=10\frac{1}{2}\ per\ hour.$

Therefore, the answer is $10\frac{1}{2}\ per\ hour.$

Nina operates a dog walking service. She charges a flat fee of $15 plus $5 per hour. Which equation represents this linear relat

densk [106]

Equation for linear relationship is y=mx+b, where m is slope (rate of change), and b is y-intercept. Y-intercept is where you start of at. Like if I had 20 dollars and started earning 5 dollars each day, my y-intercept would be 20 dollars.

Your rate of change is $5 dollars PER HOUR, and y-intercept is $15 dollars. this is because it is a flat fee. She could walkyour dog for 5 minutes but she still charges 15 dollars.

y=5x+15
