Answer:
The distance formula is a formalization of the Pythagorean Theorem using (x,y) . They are the same thing (but the distance formula is for working out the distance between two points and Pythagoras theorem is for working out the missing length in a right-angled triangle) in two different contexts.
Step-by-step explanation:
Number of boys enrolled is 105
<em><u>Solution:</u></em>
Given that, At a local preschool there is s as ratio of 3 boys to every 4 girls
There are 245 total preschoolers
Ratio of boys and girls = 3 : 4
Number of boys : number of girls = 3 : 4
Let the number of boys be 3x
Let the number of girls be 4x
Total number of preschoolers = 245
Therefore,
number of boys + number of girls = 245
3x + 4x = 245
7x = 245
x = 35
Number of boys = 3x = 3(35) = 105
Thus number of boys is 105
Answer:
Step 1: Simplify both sides of the equation.
Step-by-step explanation:
x+−13=13
Answer:
$49560
Explanations:
The amount deposited is the principal
The principal, P = $24,000
Interest rate, r = 7.25% = 7.25/100 = 0.0725
Time, t = 10 years
Since the interest is compounded continuously, the amounte^ formula is given as:
Substitute P = 24000, r = 0.0725, and t = 10 into the formula above:
$49560 will be in the account after 10 years if no withdrawal or deposit is made
