Step-by-step explanation:
you would do 7.8 times 0.5 and would get 3.9. You would add 7.8 and 3.9 and get 11.7 That is your answer
Answer:
The slope intercept equation of the line is:
<u> y = (9/8)x - (3/8)</u>
Step-by-step explanation:
- They give us 2 parametric equations to arrive at y = mx + b (Slope intersection equation)
1. X = 8t + 3
2. Y = 9t + 3
- We first convert in terms of t to compare both equations:
1. x = 8t + 3
x - 3 = 8t
t = (x - 3) / 8
- Same for the following:
3. y = 9t + 3
y - 3 = 9t
t = (y - 3) / 9
- Now equating by comparing both equations, we will find y:
(x - 3) / 8 = (y - 3) / 9
9x -27 = 8y -24
9x - 3 = 8y
- Clearing and comparing both parameters gives us:
y = (9/8)x - 3/8
Answer:
Using a globe and some string might be more convenient. A great circle is the shortest path between any two points on the earth's surface.

Answer:
110°
Step-by-step explanation:
This quadrilateral have the same size in AD and CD, and BA and CA, so it means that, if you cut this figure in the middle (from B to D), the two triangles will be identical, and the sum of the internal angles of a triangle is 180°, so:
(110°÷2) + (30°÷2) + <C = 180°
55° + 15° + <C = 180°
70° +<C = 180°
<C = 180° - 70°
<C = 110°
And you can test it making the sum of the internal angles of the quadrilateral. The sum of the internal angles of a quadrilateral is 360°, and the angles A and C have the same measure because AD=CD and AB=BC, so:
<A + <B + <C + <D
110° + 110° + 110° + 30° = 360°
