-3 = 7-10
Subtract 10 from 7 and you will get -3
Answer:
length = 20 mt
Width = 16 mt
Step-by-step explanation:
Let the length of the field be x
width of the field be y
Hence formula of the perimeter is given as
P=2(x+y)
P=72(given)
72=2(x+y)
Dividing both sides by 2 we get
x+y=36---(A)
Also given that width of the parallelogram is 4 meters less than its length
Hence
y=x-4
or x-y=4 ---(B)
Adding A and B
2x=40
x=20
y=x-4
y=20-4=16
Hence length = 20 mt
Width = 16 mt
Answer:
9 cm.
Step-by-step explanation:
Let x be the number of hours.
We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of 
, so the snow melted in x hours will be 
.
Since initially there was 10 cm of snow, so the depth of snow after x hours will be:
To find the depth of snow after 3 hours we will substitute 
in our expression.
Therefore, the depth of the snow on cherry street after 3 hours will be 9 cm.
Answer:
46.08
Step-by-step explanation:
you have to make your percentage a decimal, which 60% will be .60 and 20% will be .20. you then multiply your initial number which is 36 by .60 and add that on because youre adding 60%. After that you will multiply that given number by .20 and you subtract what that product is from your last product you received (36x.60) which if im not mistaken will give you $46.08.
