Answer:
1st answer
Step-by-step explanation:
From pythagorus theorem.
Since hypotenuse
The answer is 9 for this one
Answer:
10c = 20
5c = 5
Step-by-step explanation:
Let x be the number of 10c coins; let y be the number of 5c coins. The total is $2.25, so the amount of 10c and 5c coins will add to that. Simita has 25 coins, so x and y, the number of coins, will have to add to 25. Hence, solve the simultaneous equation.
10x + 5y = 225 (1) - times by 0
x + y = 25 (2) - times by 5
10x + 5y = 225 (1)
5x + 5y = 125 (2)
Then, take equation 2 away from equation 1.
5x = 100
x = 20
Substitute x back into the original equation.
x + y = 25
20 + y = 25
y = 5
200+30+0.2+0.05+0.001=230.251
The length and width of the conservatory are both 4.5 meters
<h3>How to determine the length and the width?</h3>
From the figure, we have the following highlights:
- Length = 3 units
- Width = 3 units
A unit = 1.5 meters
So, we have:
Width = Length = 3 * 1.5 meters
Width = Length = 4.5 meters
Hence, the length and width of the conservatory are both 4.5 meters
