Make a proportion to find the cost for 12 flowers based on the price for 4 flowers.
4/10=12/x
Cross multiply and you get 4x=120 Divide 4 on both sides of the equation.
X is $30.
Then, you find the unit price of 1 flower by dividing 10 by 4. Each flower cost $2.50.
Convert 20% to decimal which is 0.2.
Multiply 0.2 by 2.5 and you get 0.5. Subtract 0.5 from 2.5 to get 2.
Write an equation using the information: $2 for each flower and you only have $30 to spend.
The equation is 2x=30. Divide 2 on both sides and you get x=15 flowers
Answer:
12
Step-by-step explanation:
The least common multiple (LCM) of 3 and 4 is 12. Adam would have to divide each rectangle into a minimum of 12 parts.
_____
His shading would be 4 parts (4/12 = 1/3) of one of them and 3 parts (3/12 = 1/4) of the other.
__
3 and 4 have no common factors, so their LCM is their product. 3×4 = 12.
The percentage of the original activity in the sample remains after 17.5 days is obtained as N(t) / No x 100%.

What is half life?</h3>
Half-life is the time required for a quantity to reduce to half of its initial value.
The original activity in the sample that remains after 17.5 days is calculated from half life equation as shown below;
N(t) = No(¹/₂)^t/h
where;
- N(t) is the mass of the substance remaining
- No is the initial mass of the substance
- t is time elapsed = 17.5 days
- h is the half life of the substance
percentage of the original activity in the sample remains after 17.5 days;
= N(t) / No x 100%
Thus, the percentage of the original activity in the sample remains after 17.5 days is obtained as N(t) / No x 100%.

Answer:
I am you helper
Step-by-step explanation:
Yes! In decimals, it is based on the first number. If it is the same number, it is based on the second number. This trend continues unless it is a repeating decimal, where you are forced to round it.
0.65
0.437
6 > 4 so it is greater, yes.
