Answer: 0.249
Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.
We can think of 24.9% as the ratio 24.9 to 100 or 24.9 ÷ 100.
Remember that dividing by 100 moves the decimal point two places to the left so 24.9 ÷ 100 will move the decimal point two places to the left which would give us .249 or 0.249.
Therefore, 24.9% can be written as the decimal 0.249.
Answer:
I solve it by substitution
y=x^2+4x
-x^2+9x+(x^2+4x)+13=0
13x+13=0
13x=-13
x= -13/13
x= -1
y=x^2+4x=1-4
y= -3
Step-by-step explanation:
Alright, lets gets tarted.
Suppose there are x rows of tomato plants Krystyn make.
Again suppose there are n plants in each row.
We could find total plants by multiplying number of plants in each row with number of rows.
Hence total number of plants will be = 
But as per question, total number of plants are 54. It means

Now, the number of plants in each row was 3 more than the number of rows means

Putting this value of n in first equation we made


Subtracting 54 in both sides


Factoring

Means x = 6 or x = -9
The number of rows can not be negaive.
Hence x = 6
It means number of rows of tomato plants will be 6. : Answer
Hope it will help :).

Answer: The distance from the school to the park = 9 miles.
Step-by-step explanation:
Given: The distance from the school to the library is 12 miles.
The distance from the school to the park is 75% of this distance.
The distance from the school to the park = 75% of (distance from the school to the library)
= 0.75 × (12 miles)
= 9 miles
Hence, the distance from the school to the park = 9 miles.
