G=32 B=55
Step-by-step explanation:
55+32=87
I know this answer is right bc I got it right on my ws.
For this case we have that by definition, the density is given by:
![d = \frac {M} {V}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%20%7BM%7D%20%7BV%7D)
Where:
M: It is the mass of the diamond
V: It is the volume of the diamond
According to the data of the statement we have:
![d = 3.5 \frac {g} {cm ^ 3}\\M = 0.10 \ g](https://tex.z-dn.net/?f=d%20%3D%203.5%20%5Cfrac%20%7Bg%7D%20%7Bcm%20%5E%203%7D%5C%5CM%20%3D%200.10%20%5C%20g)
So the volume is:
![V = \frac {M} {d}\\V = \frac {0.10 \ g} {3.5 \frac {g} {cm ^ 3}}\\V = 0.02857\\V = 0.03 \ cm^3](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%20%7BM%7D%20%7Bd%7D%5C%5CV%20%3D%20%5Cfrac%20%7B0.10%20%5C%20g%7D%20%7B3.5%20%5Cfrac%20%7Bg%7D%20%7Bcm%20%5E%203%7D%7D%5C%5CV%20%3D%200.02857%5C%5CV%20%3D%200.03%20%5C%20cm%5E3)
Thus, the volume of the diamond is approximately ![0.03 \ cm ^ 3](https://tex.z-dn.net/?f=0.03%20%5C%20cm%20%5E%203)
Answer:
![0.03 \ cm ^ 3](https://tex.z-dn.net/?f=0.03%20%5C%20cm%20%5E%203)
Answer:
x = 2
Step-by-step explanation:
Given
- 7x - 3x + 2 = - 8x - 2 ← simplify left side
- 10x + 2 = - 8x - 2 ( add 8x to both sides )
- 2x + 2 = - 2 ( subtract 2 from both sides )
- 2x = - 4 ( divide both sides by - 2 )
x = 2
389 children and 224 adults were at the pool that day.
Step-by-step explanation:
Cost of one child ticket = $1.75
Cost of one adult ticket = $2.25
Total people = 613
Total receipts worth = $1184.75
Let,
Number of children = x
Number of adults = y
According to given statement;
x+y=613 Eqn 1
1.75x+2.25y=1184.75 Eqn 2
Multiplying Eqn 1 by 1.75
![1.75(x+y=613)\\1.75x+1.75y=1072.75\ \ \ Eqn\ 3](https://tex.z-dn.net/?f=1.75%28x%2By%3D613%29%5C%5C1.75x%2B1.75y%3D1072.75%5C%20%5C%20%5C%20Eqn%5C%203)
Subtracting Eqn 3 from Eqn 2
![(1.75x+2.25y)-(1.75x+1.75y)=1184.75-1072.75\\1.75x+2.25y-1.75x-1.75y=112.00\\0.50y=112.00](https://tex.z-dn.net/?f=%281.75x%2B2.25y%29-%281.75x%2B1.75y%29%3D1184.75-1072.75%5C%5C1.75x%2B2.25y-1.75x-1.75y%3D112.00%5C%5C0.50y%3D112.00)
Dividing both sides by 0.50
![\frac{0.50y}{0.50}=\frac{112.00}{0.50}\\y=224](https://tex.z-dn.net/?f=%5Cfrac%7B0.50y%7D%7B0.50%7D%3D%5Cfrac%7B112.00%7D%7B0.50%7D%5C%5Cy%3D224)
Putting y=224 in Eqn 1
![x+224=613\\x=613-224\\x=389\\](https://tex.z-dn.net/?f=x%2B224%3D613%5C%5Cx%3D613-224%5C%5Cx%3D389%5C%5C)
