Mango is setting up folding chairs for a meeting. If he arranges the chairs in 9 rows each of the same length, he has additional 3 chairs left over. If he arranges the chairs
in 7 rows each of that same length again, he has 19 additional chairs left over,
• Write and solve an equation to determine how many chairs Mango has in each
row.
• Then, using that information, determine the total number of chairs Mango has.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
