Angle A = arctan(12/5) = 67.4 degrees
Angle A = arccos(5/13) = 67.4 degrees
yes the answer was the same
Answer:
78.26
Step-by-step explanation:
130+50= 180
.45-.15+2=2.3
180/2.3=78.26
36.89 total divided by the 8.6 gallons he bought = 4.2 so the price per gallon would be $4.20
The equation of the line would be
y = mx+b
where m is the slope, b is the y intercept.
<span>The line will form a triangular region in the first quadrant. Its area would be 1/2 base times height. The height is the y intercept
and the base is y intercept divided by slope. Therefore,</span>
A = b^2/2m
At point (2,5)
5 = 2m+b
Substitute that in the area
A = b^2/5-b
to find the least area, differentiate the area with respect to the height and equate it to 0
dA/db = 0
<span>find b and
use that to find m. Then, you can have the equation of the line.</span>
Answer:
The system of equation can be used for determine the number of small and the large dogs groomed are
x + y = 22
43x + 75y = 1234
Step-by-step explanation:
Let us assume that the number of small dogs groomed be x.
Let us assume that the number of lagre dogs groomed be y.
As given
Paws at play made a total of $1,234 grooming 22 dogs.
Than the equation becomes
x + y = 22
Paws at play charges $43 to groom each small dog and $75 for each large dog.
Than the equation becomes
43x + 75y = 1234
Therefore the system of equation can be used for determine the number of small and the large dogs groomed are
x + y = 22
43x + 75y = 1234
