Answer:
19.5 miles
Step-by-step explanation:
The question is represented in the image attached.
∠A = 45°, ∠B = 45° + (216° - 180°) = 81°
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
45° + 81° + ∠C = 180°
126 + ∠C = 180
∠C = 180 - 126
∠C = 54°
The sine rule states that for a triangle with sides a, b, c and their corresponding opposite angles A, B and C. The following rule holds:
b = length of beginning of submarine to end point. Using sine rule:
Answer:
The x-axis should be the units and the y-axis should be the prices.
Step-by-step explanation:
IF you guys have time, this is my explanation:
In a graph, we always think of "rise over run" or "y over x." Another way to write this is "y PER x." For example, 90 percent is "90 per 100," which can also be written as, "90 OVER 100." So, do we have price per unit or unit per price?
The answer would be, "unit per price." This is because the question asks to compare the unit prices, not the price units. Think unit price = unit PER price. Price unit = price PER unit. So the question asks, "For every unit, what will the price be?"
Therefore, units is x and prices are y because we are trying to compare price per unit, which we now know is y PER x.

Answer: 30 feet</h3>
===================================================
Explanation:
He has 90 feet of fencing overall. This is the perimeter of the rectangle as its the distance around all four sides.
Two of the opposite sides are the width = 15 ft. So we have 15+15 = 30 feet taken up and 90-30 = 60 feet left for the other two opposite sides to add to. Call each of those sides x
x+x = 60
2x = 60
x = 60/2
x = 30
The other side must be 30 feet long.
This rectangle is 30 by 15
perimeter = 30+15+30+15 = 45 + 45 = 90
which helps confirm we have the right answer
---------------
Or you can solve this way
P = 2*(L+W) is the perimeter of a rectangle with length L and width W
Plug in the perimeter P = 90 and the width W = 15. Solve for L
P = 2*(L+W)
90 = 2*(L+15)
2(L+15) = 90
L+15 = 90/2
L+15 = 45
L = 45-15
L = 30
5-(8v+5) = -4(1+3v)
5-8v-5 = -4 - 12v
-8v = -4 - 12v
4v = -4
v = -1
Answer:
6x+1
Step-by-step explanation:
1. Add the x
4x+2x=6x
2. Add the numbers
8-7=1
3. Add everything
6x+1
Hope this helps!
