Answer:
3.5 grams of peanuts per 1 gram of raisins
Step-by-step explanation:
You have the table with the following information
14 grams of peanuts = 4 grams of raisins
21 grams of peanuts = 6 grams of raisins
35 grams of peanuts = 10 grams of raisins
you need to find:
? grams of peanuts = 1 gram of raisins
So, we need to find the constant of proportionality.
14/4 = 7/2 = 3.5/1
Therefore, 3.5 grams of peanuts = 1 gram of raisins
Answer:
The slope is 3/8
Step-by-step explanation:
The difference in the rise (y-values) 3, divided by the difference in the run (x-values) 8, is 3/8.
You can see this by looking at the places where the graphed line crosses the grid, and counting the squares in each direction between those points, or you can use the formula (y - y₁) ÷ (x - x₁)
Using the values of coordinates (3,1) and (-5, 4)
4 -(1) ÷ 3 - (-5)
3 ÷ 8
3/8
Answer:
- 5/7
Step-by-step explanation:
y2 - y1 / x2 - x1
(-3 - 2) / (3 + 4)
<u>- 5/ 7</u>
<u></u>
1243 I think is right because you just times each individual number by six
Answer:
B. 73.19 mi/hr
Step-by-step explanation:
First we need to define the angles from a common reference. Robin's watercraft is moving 75° west of south, which is the same as 15° south of west. The river is flowing at 75° south of west.
The watercraft velocity relative to the water is:
wx = 70 cos 15° ≈ 67.615
wy = 70 sin 15° ≈ 18.117
The river's velocity is:
rx = 6 cos 75° ≈ 1.553
ry = 6 sin 75° ≈ 5.796
Robin's net velocity is:
vx = wx + rx ≈ 69.168
vy = wy + ry ≈ 23.913
The speed (magnitude of velocity) is:
v = √(vx² + vy²)
v ≈ √(69.168² + 23.913²)
v ≈ 73.19
