In total $130 is there in the piggy bank.
Given that, in a piggy bank, there are four $10 bills and eighteen $5 bills.
We need to find out how much money is there in the piggy bank.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the total amount of money in the piggy bank be x.
So, x=4×10+18×5
=40+90
=$130
Therefore, in total $130 is there in the piggy bank.

Option A:
Option C:
Solution:
Given ΔRST similar to ΔABC.
To determine which statements are true for the given similarity triangles.
Option A:
By the similarity theorem,
If two triangles are similar, then the corresponding angles are equal and the corresponding sides are in the same ratio or proportion.
Therefore,
It is true.
Option B:
By the similarity theorem, corresponding angles are equal.
∠S is corresponding to ∠B.
So, .
That means ∠S is not corresponding to ∠A.
Therefore, it is false.
Option C:
By the similarity theorem, corresponding angles are equal.
∠R is corresponding to ∠C.
Therefore .
It is true.
Option D:
We already, proved in option A that
Therefore, .
It is false.
Option A and Option C are true.
Hence and .
Answer:
y = √(x - 2) / 2
Step-by-step explanation:
y = 2x^2 + 2.....switch ur x and y and solve for y
x = 2y^2 + 2
x - 2 = 2y^2 ...divide both sides by 2
(x - 2) / 2 = y^2...now take the sqrt of both sides, eliminating the ^2
(√ (x - 2) / 2) = y
f(x) = 2x – 23
f(20) = 2*20 - 23
f(20)) = 40 - 23 = 17
answer: 17 cookies
