On a average day a horse might drink 50 la sheep might drink 4 l and a chicken might drink 200ml how much water would a farm with 3 horses 15 sheep and 12 chickens need for a day
Answers
sheep-4l
chicken-200ml
first you have to convert all the symbols into one, so we'll convert liters into milliliters,
1000ml=1l
horse= 50 ×1000=50000ml
sheep=4×1000=4000ml
chicken= 200ml
so now we have to multiply them by the number of animals,
h=50000ml×3=150000ml
s=4000×15=60000ml
c=200×12=2400ml
now add them together,
150000+60000+2400=212400ml
convert it into litres,
212400÷1000=212.4l
answer= 212.4 l

Step-by-step explanation:
When you convert fraction numbers to decimal numbers, remember they are written like this:
whole . parts
In 13 1/2, you have 13 wholes and 1/2 parts. The decimal number would look like 13 . parts
To find the decimal for 1/2, put into your calculator 1 ÷ 2. The answer will be 0.5 Write "5" for parts. The decimal where 0.5 is will line up with the decimal in the decimal number.

Answer:
x=-6
Step-by-step explanation:
We want to get the variable by itself
In order to do this, we must multiply both sides by 6. Since x is being divided by 6, we want to do the opposite.
x/6=-1
6*x/6= -1*6
x=-6
Hope this helps! :)
Answer:
-6
Step-by-step explanation:
You multiply both sides by 6 so x/6*6=-1*6 so x=-6

15 percent is 3/20 of a whole, meaning that 1/20 of a whole would be 3. Then, multiply the 1/20 by its denominator.
3*20= 60
Answers
so
100-15=85
discount 15 is the same as finding 85%
100-20=80
20% off is the same as finding 80%
180*.85=153
200*.80=160
153<160
sport city is better deal
180 - 27 = $153 paid.
20% of 200 = (200 * 0.2) = 40.
200 - 40 = $160 paid.
Therefore Sport City offered the better deal.

Answer:
The best option is;
A triangle with three equal sides all longer than 12 inches
Step-by-step explanation:
The cross sectional area of the square prism that passes through points A, B and C is found as follows;
Shape of cross section ABC = Triangle
Base, AB of the triangle is given by;
AB = √(8² + 8²) = √128 = 8·√2
Side, AC of the triangle is given by AC = √(8² + 12²) = 4√13
Therefore, the height of the triangle is given as follows;
Height, h = √(4·√13)²-(4·√2)² = 4·√11
The area of the cross section then is 0.5 × Base × Height
= 0.5 × 8·√2 × 4·√11 = 16·√22
A triangle with 3 equal sides of 8 inches has an area of 4×8×sin(60) = 16√3
A triangle with 2 equal sides of 12 inches and one side of 8 inches has an area of 4×12×sin(60) = 24√3
Therefore since 16·√22 > 24√3 > 16√3, the best option is a triangle with three equal sides of all longer than 12 inches.
