In the fifth grade there are 4/5 as many students who do not have glasses as those who do wear glasses if there are 60 students
Allushta [10]

Answer:

300 students

Step-by-step explanation:

Since 4/5 of students do not wear glasses, 1/5 of students do.  

There are 60 students who wear glasses, so let 'x' represent the number of students who wear glasses

(1/5)x = 60     is our equation.  "One-fifth of the number of students who wear glasses is 60"

Now solve for x

(1/5)x = 60

    x = 300    (multiply both sides by 5 to get rid of the fraction)

Find the missing angle measures in the kite
BigorU [14]

Answer:

ok so we know that a triangle is 180 degrees.

so i can take the info and figure out the f,g,d,i all equal 90 degrees so i can figure out that 90+51=141

180-141=39

so angle a is 39

the two bigger triangles are equal and the two smaller ones are equal...

so we know that

a=39

b=62

c=51

d=90

e=39

f=90

g=90

h=28

i=90

Step-by-step explanation:
