Juanita has saved 30% of the money that she needs to buy a new bicycle.
Mnenie [13.5K]

well, the bicycle costs "x" which is the 100% of its price, we know she has 30% thus far, and we also know that that is 66 bucks.

\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 66&30 \end{array}\implies \cfrac{x}{66}=\cfrac{100}{30}\implies \cfrac{x}{66}=\cfrac{10}{3} \\\\\\ 3x=660\implies x\cfrac{660}{3}\implies x=220

SBC is an isosceles triangle with main vertex S.
stira [4]

Answer + Step-by-step explanation:

1) D be the symmetric of B with respect to C then CD = BC

A the symmetric of C with respect to B then AB = BC

We obtain :

CD = BC

AB = BC

Then AB = CD

2) m∠SBA = 180 - SBC = 180 - SCB = m∠SCD

3) we have :

BA = CD

BS = CS

m∠SBA = m∠SCD

Then

the triangles SBA and SCD are congruent

4)

the triangles SBA and SCD are congruent Then SA = SD

Therefore SAD is an isosceles triangle.

Mamont248 [21]

Step-by-step explanation: First you take the equation: f(x)= 0.86x-0.09

Then you plug in x witch in this case is 18 so f(18)=0.86(18)-0.09= 15.39 So round to the nearest whole number and you get 15.
