Answer:
A: 20:10=2:1
B: y=2x
c he can have 2 flowers per seed packet
Step-by-step explanation:
A: When you look at the coordinates of the graph, you can see the proportionallty at point (10/20)
B: the equoation is proportionalty multplied by x + y axis section (in this case 0)
C: The proportionality explains the relationship:
x represents the flowers
y represents the seed packets

Answer:2^7 ≠ 7^2
Step-by-step explanation:
2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2
The only factor is 2
7^2 = 7 * 7
The only factor is 7
Comparing the factors when written as a repeated multiplication,
2^7 and 7^2 have no common factor :
2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2 = 128
7^2 = 7 * 7 = 49
1 ton = 2,000 pounds
3 tons = $3,840
2,000 lbs = $3,840
Divide by 2,000
1 lbs = $1.92
The price per pound is $1.92
Answer:
Correct answer: C. Ca = 4 Cb
Step-by-step explanation:
Given: Ra = 4 Rb
Ca : Cb = ?
Using the following formula to calculate the circumference of a circle:
C = 2 R π
Cb = 2 Rb π
Ca = 2 Ra π = 2 ·( 4 · Rb) · π = 4 · (2 Rb π) = 4 · Cb
Ca = 4 · Cb
