Answer: 169.7
Step-by-step explanation:
Given that Air atmosphere level = 96kp
For every 1000m= 11.6/100 of 96kp decrease
For every 1000m= 96 - 11.6/100 × 96
= 96 - 11.14
= 84.86
If 1000m pressure decreases= 84.86
2000m pressure will decrease = ??
Let the missing value be x, and the equation be stated as:
1000 = 84.86
2000= x
Then cross multiply
1000x = 2000 x 84.86
1000x = 169,720
Divide both sides by 1000 to get the value of x
x = 169,720/1000
x =169.72 = ~ 169.7

Step-by-step explanation:
If x is the mass of 30% copper alloy, and y is the mass of 65% copper alloy, then:
x + y = 80
0.30x + 0.65y = 0.51(80)
Solving the system of equations using substitution:
0.30x + 0.65(80 − x) = 0.51(80)
0.30x + 52 − 0.65x = 40.8
11.2 = 0.35x
x = 32
y = 80 − x
y = 48
The metalworker needs 32 kg of 30% copper alloy and 48 kg of 65% copper alloy.
Answer:
17%
Step-by-step explanation:
- The total corporation shares is 100%
- If Ella owns 15% of Fitz,the remaining shares is 100-15=85%
- If there are 5 shareholders and they all own equal shares,the percentage for each shareholder will be;85/5=17% each
You can divide it and get 2.2
