Answer:
$4,160,000
Step-by-step explanation:
First, find the length of the new road in km using Pythagorean Theorem.
According to Pythagorean Theorem:
c² = a² + b²,
Where, c is the longest leg, which is the hypotenuse, a and b are the 2 other legs of the ∆.
Since we are calculating the lenght in km, convert each lenght of the two legs of the ∆ into km.
1 km = 1,000 m
10,000 m = 10 km
24,000 m = 24 km
c² = 24² + 10²
c² = 576 + 100
c² = 676
c = √676
c = 26 km
Lenght of the new road = 26 km
If cost of construction is $160,000 per kilometer, therefore, cost of constructing 26 km road = 160,000*26 = $4,160,000
3x-12y = 5
-x+3y = 9
First step is to make the coefficient of either x or y same.
3x-12y = 5
(-x+3y = 9)3
3x-12y = 5
-3x+9y = 27
-4y = 32
y = -8
The measure of a center and
variation are appropriate for the data is the mean or average. In this, you are
to add the data collected by Kinesha and then divide it by the number of data
obtained by Kinesha. The measure of center and variation is the mean scores.
Using the catchphrase SohCahToa, we can determine that the cosine ratio is equal to the length of the side adjacent to the angle over the length of the hypotenuse of the right triangle.
To find the cos∠A, we will look for side lengths BC and AB.
cosA =
Since
is already in it's simplest form, we can conclude that the cosine of ∠A is
.
Hope this helps! :^)
