Answer:
Step-by-step explanation:
there is 15 emperor penguins...they make up 30% of all the penguins
so 30% of all the penguins is 15
let x represent all the penguins
turn ur percent to a decimal
0.30x = 15
x = 15 / 0.30
x = 50 <===== 50 total penguins
Hi there
Let's order the transactions
on May 1. 150
less On May 20 100 books were sold
Less June 3, 31 books were purchased by the students
Add on June 15 25 books arrived
Add On June 17, a shipment of 150 books arrived
So
the number on hand on June 17
150−100−31+25+150
=194....answer
Hope it helps
Using Pythagorean’s theorem, the side length is sqrt(89)
900$ loss
X/150=.05/1
x= 142.5
120(142.5)=17100
120(150)= 18000
18000-17100= 900
