Answer & Step-by-step explanation:
Since we use 5 parts blue and 3 parts red, the total sections is 8.
28/8 = 3.5
We want to find the red which is 3 parts.
3.5 * 3 = 10.5.
Your answer should be 10.5 pints of red.
Hope this helps!
Answer:
3.98
Step-by-step explanation:
From the above question,
Cost is directly proportional to the Number of pounds
Hence:
C ∝ N
= C = kN
Where k = Proportionality constant
We are told:
Last week, she bought two pounds and paid $7.96,
Hence:
7.96 = 2k
k = 7.96/2
k = 3.98
This week she bought only one half pound and paid $1.99,
1.99 = k × 1/2
k = 1.99/ 1/2
k = 3.98
Hence, the constant rate of proportionality is 3.98
Answer:
1
Step-by-step explanation:
The rules for significant figures are:
- Non-zero digits are always significant.
- Zeros between significant digits are also significant.
- Trailing zeros are significant only after a decimal point.
In 13822, all of the digits are non-zero. So the first significant figure is 1.
