Answer:
35
Step-by-step explanation:
Let x represent the HCF of the ages. Then we can have ax = 10 represent Lena's age, and bx can represent her dad's age.
The LCM will be abx = 14x, so we have ab = 14.
Factors of 14 are 1·14 and 2·7. Since the ratio of ages is between 30/10 = 3 and 45/10 = 4.5, we must have b/a in that range. This will be the case for ...
a=2, b=7
For a=2 and ax=10, we have x=5.
The dad's age is bx = 7·5 = 35.
Answer:
$4.48
Step-by-step explanation:
First, you have to convert the percentage into a decimal.
12% x 100 = 0.12
Second, you multiply the decimal with the cost of the product before tax.
$4 x 0.12 = $0.48
This number is the amount of money you will have to pay in tax.
Third, you add the tax amount to the original cost of the product to get the total price.
$4 + $0.48 = $4.48
Answer:using the square root on both sides of the equation
