7:8 it could also be written as 7 to 8 or 7/8
Since we need to find out SIXTH to FIFTH grades we have to put the sixth graders first. Hope this helps and have a great day!
Answer:
72 & tends to increase
Step-by-step explanation:
just took the test
Answer:
In simplified fraction, it is expressed as : 1/16, 1/4, 3/8, 1/4, 1/16.
Step-by-step explanation:
The discrete probability distribution for the random variable is as follows:
The number of tails possible in four tosses of a coin are 0,1,2,3,4
The total number of outcomes are
The Probability distribution is
X 0 1 2 3 4
P(X) 1/16 4/16 6/16 4/16 1/16
Therefore, In simplified fraction, it is expressed as : 1/16, 1/4, 3/8, 1/4, 1/16.
Answer:
I dont know how many pounds are in an ounce but I'll give you an explanation using kilograms and grams as an example and I'll talk you through it
Step-by-step explanation:
there are 1000 grams(g) in a kilograms (kg) just so you know
let's say I have a 13 g box of cereal for $3.99.
I do a ratio to work out 1 kg
13 g : $3.99
1000g : x
In your case your going to write
13 ounces : $3.99
[here write how many
ounces are in a pound] : x
to find x you 1st have to take the 2 numbers you do know and divide them
so in my example I do 1000g÷13 g = 76
then I take 76.92 and I multiply it by the other side
$3.99 x 76.92 = 306.91
for me 1kg of cereal is worth $306.91
all you need to do is replace my 1 kg with how many ounces are in a pound

<u>Solution</u><u>:</u></h2>
We all know that,
- All animals have 2 eyes.
- All cows have 4 feet
- All hens have 2 feet
So, Let the no. of cows be x and chickens be y
According to question,
- Total number of eyes = 162
Framing equation,
⇛ Eyes of cows + Eyes of chickens = 162
⇛ 2x + 2y = 162
⇛ 2(x + y) = 162
⇛ x + y = 162/2 = 81 -----------(1)
According to question(Cond.-1)
- Total number of feet = 270
Framing equation,
⇛ Feet of cows + Feet of chickens = 270
⇛ 4x + 2y = 270
⇛ 2(2x + y) = 270
⇛ 2x + y = 135 ----------(2)
Subtracting eq.(1) from eq.(2),
⇛ 2x + y - (x + y) = 135 - 81
⇛ 2x + y - x - y = 54
⇛ x = 54
Putting value of x in eq.(1),
⇛ 54 + y = 81
⇛ y = 81 - 54
⇛ y = 27
⚘ So, Total number of animals,
- Number of cows = x = 54
- Number of chickens = y = 27
Hence, solved !
