Answer:
0.33 litres
Step-by-step explanation:
If a mug can hold a volume of m litres, then a bowl can hold a volume of m+0.07 litres. The total volume held by the given containers is ...
3(m +0.07) +4m = 2.52
7m +0.21 = 2.52 . . . . . . . . simplify
7m = 2.31 . . . . . . . . . . . . . subtract 0.21
m = 0.33 . . . . . . . . . . . . . divide by 7
Each mug can hold 0.33 litres.
Answer:
f = (N² - H)/6
Step-by-step explanation:
Step 1: Write equation
N² = 6f + H
Step 2: Solve for <em>f</em>
- Subtract H on both sides: N² - H = 6f
- Divide both sides by 6: (N² - H)/6 = f
- Rewrite: f = (N² - H)/6
Answer:
Ratio of tin to silver in the bar is 2:3
Step-by-step explanation:
We are given the following in the question:
10 kg of tin loses 1.375 kg in the water
Percentage of weight lost by tin =
5 kg of silver loses 0.375 kg
Percentage of weight lost by silver =
20 kg bar loose 2 kg in water.
Percentage of weight lost by metal =
Let x be the amount of tin and y be the amount of silver in bar.
Thus, we can find the ratio as:
is the required ratio.

Step-by-step explanation:
The three angles create a triangle. The sum of the angles of a triangle is always 180°.
Solving for x,
45° + 35° + x = 180°
x = 100°
