Answer:
Part A: y=5x
Part B: B and D
Step-by-step explanation:
The ratio of the number of cases to the total cost is 1:5. So, an equation that can be modeled by this situation in slope-intercept form is y=5x.
The unit rate actually does equal the constant of proportionality, so this is not true.
The unit rate of the number of cases per dollar is 1/5, so this is true.
No, the graph starts on the origin, so this isn’t true.
Points (0,0) and (1,5) are on the graph, so this is true.
25 cases will not cost $120, they will cost $125.
Answer:
Diameter = 9
Step-by-step explanation:
Let the diameter be represented as x.
Based on the secant-tangent theorem, the following equation representing the relationship between the segments would be:
(16 + x)(16) = 20²
256 + 16x = 400
Subtract 256 from each side
16x = 400 - 256
16x = 144
Divide both sides by 16
x = 144/16
x = 9
Diameter = 9
Answer:
6.25 gm left
Step-by-step explanation:
Find the number of half lives in 26.3 years
26.3 / 5.26 = 5 half lives
(1/2) ^5 = 1/32 nd of the original will be left
1/32 * 200g = 6.25 gm left
Answer: ↓↓
Step-by-step explanation:
55,555 = 50,000 + 5,000 + 500 + 50 + 5
50 = 10 × 5
500 = 100 × 5
50,00 = 1000 × 5
50,000 = 10,000 × 5
