Answer:
3 m : 4 cm, 3 m/4 cm, 3 m to 4 cm
Step-by-step explanation:
The actual playground will have an area of 72 m², and have one side be double the other, because the scale drawing does so too.
We can make a system of equations: l * w = 72, l = 2w
Substitute: 2w * w = 72
Simplify: 2 * w² = 72
Divide: w² = 36
Square root: <em>w = 6 m</em> (no negatives due to distances always > 0)
Substitute: l = 2 * 6 m
Simplify: <em>l = 12 m</em>
This means that the relations of one side is <em>6 m : 8 cm</em>. That can be simplified to 3 m : 4 cm.
Round 8.1 down to 8
Round 4.2 down to 4
8(4)= 32
The estimated product is 32.
Hope this helps!

<h3>Selling Price = Rs. 851</h3>
<h3>Loss = 8%</h3>
<h3>FORMULA = 100/100 - LOSS % × SP</h3>
<h3>CP = 100/100 - 8 × 851</h3>
<h3> CP = 100/92 × 851</h3>
<h3> CP = Rs. 925</h3>

Let y represent the original price of potatoes per pound
Since he purchased the potatoes at 40% off the original price, this can represented as y*(1-0.4)
Now the weight of potatoes he purchased is x pounds, the total cost of these potatoes can be represented as x*y*(1-0.4)
The total amount of money he had is $10
The amount of money left over can be represented by the expression =
10 - x*y*(1-0.4)
where "x" is the weight of potatoes in pounds and "y" is the original price per pound of potatoes
Answer:
<h2>$128</h2>
Step-by-step explanation:
This problem is on rate.
firstly we have to find the rate at which 1 ton is sold
given that 3/8 ton is sold for $24
hence 1 ton will be sold for X
cross multiply
X = 24/3/8
inverse the denominator and multiply the result with the numerator we have
X= 24*8/3
X= $64
Now having found out that 1 ton cost $64
2 tons will cost =64*2
= $128
Therefore at this rate two tons will cost $128
