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

Find a base length of a shipping box in the shape of a triangle prism.The shipping box has a volume of 276 cubic feet,a height o

Gala2k [10]

The base length will be found as follows:
volume of the triangular prism is given by:
V=1/2ab×h
where:
10 ft
b=6.9 ft
thus the height will be found as follows:
276=1/2×10×6.9×h
solving for h we get:
h=276/34.5
h=8 ft

Solve the inequality y − 6>10

fredd [130]

if y-6 > 10, and 16-6 = 10, then y > 16 since 17-6 = 11, which is greater than 10. Any number greater than 16 can fulfil this inequality.
