The Jelly Junior High school color is made by mixing red paint with yellow paint. The ratio of red to yellow is 3 to 5 . How much red paint should be mixed with 20 oz of yellow?

7) Simplify the logarithm so that no argument contains a product, quotient or a powe \( \ln \left(e x^{3}\right)= \) a) \( 1-3 \ln x \) b) \( 01+3 \ln x \) c) \( 03-\ln x \) d) \( 3+\ln x \)

1. Fill in the Blank 16 points A sequence is defined by \( f(1)=8 \) and \( f(n)=3 f(n-1) \), for each whole number where \( n>1 \).

Cabinet \( X \) costs \( \$ 30 \), requires \( 12 \mathrm{sq} \mathrm{ft} \mathrm{of} \mathrm{floor} \mathrm{space} \),and holds 36 cu ft of files. Cabinet \( Y \) costs \( \$ 50 \), requires 6 sq ft of floor space, and holds 30 cu ft . To get maximum storage, how many of each should be purchased with a budget limit of \( \$ 450 \) and floor space of 96 sq ft? The manager should buy \( \square \) of cabinet \( X \) and \( \square \) of cabinet \( Y \). (If two possibilities provide maximum storage, use the option that involves buying at least one of cabinet \( X \) and at least one of cabinet \( Y \).)

3. Given the list of terms \( \frac{1}{3}, 1, \frac{5}{3}, \frac{7}{3}, \ldots \) a) Find the \( 15^{\text {th }} \) and \( -16^{\text {th }} \) term.

Aşağıdaki kutuların içine \( 2,4,6,8,70 \) ve 12 sayılarından dört tanesi her kutuya farkıı bir sayı gelecek şekilde yerleştirildiğinde eşitlik sağlanmaktadır. \[ \sqrt{\square}+\sqrt{\square}=\sqrt{\square+\square} \] Buna göre, kutulara yerleştirilmeyen sayılarín toplamı kaçtır? \( \begin{array}{llll}\text { (A) } 12 & \text { B) } 14 & \text { C) } 16 & \text { D) } 18\end{array} \) E) 20
