Answer:
Step-by-step explanation:
Notez que: un quintal =
une unité de poids égale à 100 kg
Un jardinier a récolté deux quintaux et trois quarts de pommes.
Le nombre total de pommes récoltées = 200 kg + 3/4 du quintal de pommes
= 200 kg + 0,381 kg
= 200,381 kg
Il vend un quintal un quart à un voisin
Le montant qu'il a vendu à un voisin = 100 + 1/4 quintal de pommes
100 + 0,127
= 100,127 kg
Il vend également 7/10 d'un quintal sur le marché du village
= 7/10 × 100 kg
= 70 kg de pommes restantes
2/5 d'un quintal à un pâtissier.
2/5 × 100 kg
= 40 kg de pommes restantes
À l'aide d'une fraction, exprimez la quantité de pomme que le jardinier a gardée pour lui.
La quantité que le jardinier lui a réservée =
200 3/4 kg - (100 1/4 kg + 70 kg + 40 kg)
200,381 kg - (210,127 kg)
no they cannot because they would not equal 180 degrees
Answer:
61.6 dollars
Step-by-step explanation:
So, lets go over what we know:
The shows orginally cost 88 dollars.
They are 30% less than that.
This basically means that the shoes will cost 70 percent of their orginal price.
We can basically find the new cost by multiplying the 88 dollars by the 70 percent.
Or, multiplying 88 by 0.7, which is the decimal form of 70%.
88*0.7=61.6
How did I get this?
Multiply 80 by 0.7:
7*8=56
We have 0.7 so it = 5.6
However, it's tens place is 80, not 8, so it will be = 56
It is the same thing in the ones place, however it is 8 not 80, so it will be 0.7*8
= 5.6
56+5.6=61.6
So 61.6 is our answer.
Hope this helps!
Answer:
<em>(a) refers to the distance around a figure</em>
<em>(c) used to find the amount of fencing</em>
<em>(e) estimated by counting the squares inside</em>
<em>(f) calculated by adding the side lengths</em>
Step-by-step explanation:
In the simplest term, the perimeter of a given figure is the distance around that figure. This also means that the perimeter of a figure can be found by adding the lengths of all its sides.
If perimeter is the distance around a figure, then it could be measured in any specified units of length e.g meter, yard, inch e.t.c.
Perimeter can also be estimated by counting the squares inside a given enclosure.
A practical application of perimeter is that it comes to play when, for example, there is a need to build a fence around an area.
<em>PS:</em>
For other options;
=> Perimeter is not given in square units. That is rather typical of area
=> Perimeter is not used to find the amount of carpeting. That is also typical of area
