Ratio of red roses to yellow roses as given in the question = 4:6
Total number of roses in the question = 50
Let us assume that the common ratio is = x
Then
4x + 5x = 50
10x = 50
x = 50/10
= 5
Then
The number of yellow roses = 6 * 5
= 30
So there are 30 yellow roses among the total of 50 roses. I hope the procedure is simple enough for you to understand. You can use this procedure for solving similar type of problems in future. I hope this has helped you.
Answer:
the cost function is Cost=7000 m*$ /R + 50.265 $/m² * R²
Step-by-step explanation:
then the cost function is
Cost= cost of side area+ cost of top + cost of bottom = 2*π*R*L * 5$/m² +
π*R² * 8$/m² + π*R² * 8$/m²
since the volume V is
V=π*R²*L → V/(π*R²)=L
then
Cost=2*π*R*V/(π*R²) * 5$/m² + π*R² * 8$/m² + π*R² * 8$/m²
replacing values
Cost=2*700 m³ /R * 5$/m² + π*R² * 16$/m² = 7000 m*$ /R + 50.265 $/m² * R²
thus the cost function is
Cost=7000 m*$ /R + 50.265 $/m² * R²
3-4y=5x-6,
<span>4y=3-5x-(-6), </span>
<span>4y=3-5x+6, </span>
<span>4y=3+6-5x, </span>
<span>4y=9-5x, </span>
<span>y=(9-5x)/4. </span>
<span>Answer: (9-5x)/4</span>
Answer:
x=-10
Step-by-step explanation:
-2x(4x-13)-7x = 176
-8x+26-7x= 176
-15x+26=176
-26 -26
-15x= 150
-15 -15
x= -10
Yes its pre algebra :)
