Answer:
- 5 lb of strawberry leaves
- 8 lb of orange slices
Step-by-step explanation:
Let "o" and "s" represent the number of pounds of orange slices and strawberry leaves in the mix, respectively. We want ...
o + s = 13 . . . . . . . . . . . . . . . total weight
1.29o +1.79s = 19.27 . . . . . .total cost
Solving the first equation for o, we can substitute that result into the second equation to get ...
o = 13 -s
1.29(13 -s) +1.79s = 19.27
0.50s +16.77 = 19.27 . . . . eliminate parentheses
0.50s = 2.50 . . . . . . . . . . . subtract 16.77
s = 5 . . . . . . . . . . . . . . . . . . multiply by 2
o = 13 -5 = 8
5 pounds of strawberry leaves should be mixed with 8 pounds of orange slices to get the desired mixture.
Answer:
Option d - 204 m
Step-by-step explanation:
Given : The atmospheric pressures at the top and the bottom of a building are read by a barometer to be 96.0 and 98.0 kPa. If the density of air is 1.0 kg/m³.
To find : The height of the building ?
Solution :
We have given atmospheric pressures,
![P_{\text{top}}=96\ kPa](https://tex.z-dn.net/?f=P_%7B%5Ctext%7Btop%7D%7D%3D96%5C%20kPa)
![P_{\text{bottom}}=98\ kPa](https://tex.z-dn.net/?f=P_%7B%5Ctext%7Bbottom%7D%7D%3D98%5C%20kPa)
The density of air is 1.0 kg/m³ i.e. ![\rho_a=1\ kg/m^3](https://tex.z-dn.net/?f=%5Crho_a%3D1%5C%20kg%2Fm%5E3)
Atmospheric pressure reduces with altitude,
The height of the building is given by formula,
![H=\frac{\triangle P}{\rho_a\times g}](https://tex.z-dn.net/?f=H%3D%5Cfrac%7B%5Ctriangle%20P%7D%7B%5Crho_a%5Ctimes%20g%7D)
![H=\frac{P_{\text{bottom}}-P_{\text{top}}}{\rho_a\times g}](https://tex.z-dn.net/?f=H%3D%5Cfrac%7BP_%7B%5Ctext%7Bbottom%7D%7D-P_%7B%5Ctext%7Btop%7D%7D%7D%7B%5Crho_a%5Ctimes%20g%7D)
![H=\frac{(98-96)\times 10^3}{1\times 9.8}](https://tex.z-dn.net/?f=H%3D%5Cfrac%7B%2898-96%29%5Ctimes%2010%5E3%7D%7B1%5Ctimes%209.8%7D)
![H=\frac{2000}{9.8}](https://tex.z-dn.net/?f=H%3D%5Cfrac%7B2000%7D%7B9.8%7D)
![H=204\ m](https://tex.z-dn.net/?f=H%3D204%5C%20m)
Therefore, Option d is correct.
The height of the building is 204 meter.
Answer:
A coefficient is the number next to a letter. It's used to multiply a variable. If there is just a variable then the coefficient is 1. For example 6x.
Step-by-step explanation:
Answer: It's C f"(x)= 15x^2+235 Hope that helps!
Step-by-step explanation:
Find the Greatest Common Factor (GCF).
GCF = 5
2. Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
5(15x^2/5+235/5)
3. Simplify each term in parentheses and that would give you 5(3x^2+47) and that's why I think it C but i'm not so sure but if you get it right can you please make me Brainliest bye and I hope you get it right!
