Answer:
6 hours
Step-by-step explanation:
Given that:
Time taken by Sam = 3 hours
Sam's rate = 1/3
Time taken : Sam + Laura = 2 hours
Sam's rate + Laura's rate = 1/2
Let time taken by Laura = x
1/3 + 1/x = 1/2
1/x = 1/2 - 1/3
1/x = (3 - 2) / 6
1/x = 1 /6
x = 6
Hencw, it will take 6 hours for Laura alone to rake leaves
in form of multiplication is 
.
<u>Step-by-step explanation:</u>
We know that factors are the numbers that are being multiplied together . As 6532*7 = 45724 .Here 6532 & 7 are the factors and 45724 is product of the factors .
Here , we need to convert to the product of multiplication
a^2-b^2-4b-4 or , :
⇒
We know by identity that , 
⇒ 
Taking common term out as -4 :
⇒
Therefore , in form of multiplication is .
Answer:
21.75 years (Almost 22 years)
21 years and 9 months. :)
Step-by-step explanation:
There are 12 months in a year.
261/12 = 21.75

3/4(12) = 9 months
Hope that helps!
13+5 = 1.5m
18 = 1.5m
m=12
her age in three years = 12+3= 15 years old
Answer:
15 students (30% of the students in class) scores a 95 on a quiz.
Therefore the total number of students (100% of the students) in class is:
N = 15 x 100/30 = 50 (students)
(This calculation is inferred from a ratio that 15/N = 30/100).
Denote the number of students who scored a 95 on a quiz is a, the total number of students in class is b.
Then the equation that related a and b is:
b = (100/30) x a
Hope this helps!
