To solve this problem you must apply the proccedure shown below:
1. You have that t<span>he largest doll is 12 inches tall. The height of each of the other dolls is 7/10 the height of the next larger doll. Therefore, you have:
We don't know the number of dolls, so:
x=12(7/10)^(n-1)
Where x is the height of the doll and n is the number of the doll
The answer is: </span>x=12(7/10)^(n-1)
● Answer:
8.995 cm
● Step-by-step explanation:
P = d + L/2
d = 3.5 cm
L/2 = 2pi×r/2
= pi×d/2
= 3.14×3.5/2
= 5.495 cm
P = 3.5cm + 5.495
= 8.995 cm

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
1/6*b-(3)=0

Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 6 as the denominator :
3 3 • 6
3 = — = —————
1 6
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
b - (3 • 6) b - 18
——————————— = ——————
6 6

When a fraction equals zero
3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
b-18
———— • 6 = 0 • 6
6
Now, on the left hand side, the 6 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
b-18 = 0
Solving a Single Variable Equation:
3.2 Solve : b-18 = 0
Add 18 to both sides of the equation :
b = 18
One solution was found :
b = 18
Answer:
11
Step-by-step explanation: Because if you add 2x3 it equals 6 so if u add 2x2 2 times thats ur answer when you add three.
The awnser is 156 so yeah
