Answer: 0.7
Step-by-step explanation:
Let the number of white cows be x
Thus, the number of brown cows be (x+12)
Hence,
x+(x+12)=60
x+x+12=60
2x+12=60
2x+12-12=60-12
2x=48
Divide both parts of the equation by 2:
x=24 white cows
x+12=36 brown cows
The number of white cows are less than one year old:

The number of brown cows are less than one year old:

The total number of cows are less than one year old:

Thus
Fraction of all the cows are less than one year old:

Answer:
or
.
Step-by-step explanation:
We have been given that there are 38 cars parked in the parking structure. There are 13 parking spaces that are empty. We are asked to find the ratio of available parking spaces to parked cars.
To find the ratio of available parking spaces to parked cars, we will set an equation as:

Therefore, the ratio of available parking spaces to parked cars is
or
.
Expand
x = 150 - 0.5x
Add 0.5x to both sides
x + 0.5x = 150
Simplify x + 0.5x to 1.5x
1.5x = 150
Divide both sides by 1.5
x = 150/1.5
Simplify 150/1.5 to 100
<u>x = 100</u>
Question 7= to work out 19% work out 1% and 20%. 25.00 1%= 0.25 10%= 2.5 so, 20% = 5 (2.5*2) 20%-1% = 19%. 5-0.25 = 4.75 = discount £25-£4.75 =20.25
0.10 *1000 = 100
0.2 * 500 = 100
