Answer:
The total length of fencing needed to enclose the kennel 74 feet.
Step-by-step explanation:
Given:
The blueprint of the rectangular kennel shows one side is 23 feet and another side is 14 feet.
As it is a rectangular shape, let the two sides be the length and the breadth of the rectangular kennel. i.e
To find:
Total length of fencing needed is to enclose the kennel. i.e
Perimeter of a rectangular kennel = ?
Solution:
we have the formula for perimeter of a rectangle as giving below.
Therefore,the total length of fencing needed to enclose the kennel 74 feet.
Answer: 13.6 or 9.2
Step-by-step explanation:
Answer:
50 degrees
Step-by-step explanation:
Okay! So first off, because this is NOT a right triangle, we can't use soh cah toa. That means we can either use the law of sines or the law of cosines.
Because we only have sides here and no angles, we are forced to use the law of cosines.
c^2 = a^2 + b^2 − 2ab cos(C)
c = 6
b = 7.5
a = 6.5
36 = 6.5^2 + 7.5^2 - 2(6.5)(7.5)cos(C)
36 = 98.5 - 97.5cos(C)
-62.5 = -97.5cos(C)
0.641 = cos(C)
angle C = cos^-1(0.641)
angle C = 50.13 which is around 50 degrees
Remember! A dumb thing i always used to do in geometry was use radians instead of degrees, be sure to use degrees here because you are looking for degrees. Radians are for things involving not degrees, but PI.
10 to the sixth power is 1,000,000. Any number to the tenth power is the number 1 in front of the number of zeros that is equal to the exponent.
Estimate the total amount you should plan to spend on gasoline for the entire trip
<em>Total distance of the trip</em> = 1430 miles
<em>After 350 miles, refill tank</em> = $35
This means 350 miles cost $35
1430 miles cost $x
solve using ratio
350 : 35 = 1430 : x
350/35 = 1430 / x
10 = 1430/x
<em>cross product</em>
10x = 1430
<em>Divide both sides by 10</em>
x = 1430 / 10
x = $143
Therefore, the total amount you should plan to spend on gasoline for the entire trip is $143
