The area of a square is 225cm². On the map drawn to scale 1 : 3 find the area of the square​

Mathematics
1 answer:
Olin [163]3 years ago
8 0

Answer:

25 cm^2

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

Area if a square = length²

225 =  length²

length = √225

length = 15

if the map is drawn to scale of 1 : 3

the length on the map = 15/3 = 5

area of the square 5 x 5 = 25

Which is the correct way to evaluate the expression 48 - (29-17)
Nadusha1986 [10]

Answer:

The correct way to evaluate this expression is my following the order of operations PEMDAS

P=Paranthesis

E=Exponents

M/D=multiply/divide

A/S=add/subtract

The first step in 48-(29-17) is to do what's inside the paranthesis

48-12 (29-17=12)

Then you would subtract 48-12

48-12=36

Your final answer is

36

Hope this helps ;)

a big water tank contained 200 litres of water. during the day, 88 l 580 ml of water was used and 200 ml leaked. how much water
algol13

The quantity of water left in the tank as described in the task content is; 111 l 220ml.

<h3>What is the amount of water left in the tank?</h3>

The tank described in the task content initially contains 200 liters, in which case, 1 liter corresponds to 1000ml.

Hence, when 88l 580ml was used, the remaining quantity of water is; 200l - (88l 580ml) = 111 l 420ml.

And finally, since 200 ml leaked, the quantity of water left is; 111l 220ml.

Mrs Adams baked some muffins. Carl eat 2/5 of the muffins and John eat 25. How many muffins were baked?
Dennis_Churaev [7]

Answer:


Well, how many were left over? Mrs. Adams has a muffin factory and made 1 million muffins. Carl ate 2/5 or 40% or 400,000 muffins, and John ate 25. 599,975 muffins were shipped for sale. That meets the stated requirements.


Hence, we have to guess there were supposed to be no muffins left over.


In that case, Mrs. Adams baked 125/3 muffins, Carl ate 2/5 of them = 50/3, leaving 75/3 = 25 for John.



Step-by-step explanation:

x muffins baked, 2/5 eaten by Carl, 3/5 left to be eaten by John, who ate 25 before running out.


3/5 x = 25

x = 25 × 5/3 = 125/3 = 41 + 2/3


Or, Start with x muffins. Carl ate 2/5 x, leaving 3/5 x. John ate 25 with zero left over. So 3/5 x = 25.


(x - 2/5 x) - 25 = 0

3/5 x = 25

x = (5/3) × 25 = 125/3.
