Answer:
15 gumballs
Step-by-step explanation:
There would have to be...
30%*50 green gumballs
We can start by converting 30% to a fraction. Any percentage is just that number over one hundred so...
30/100*50
We can simplify 30/100 by dividing the numerator and the denominator by 10...
3/10*50
Cancel out 10 and 50 (50/10=5)
3*5
15 gumballs would have to be green
Answer:
165
Step-by-step explanation:
180-15=165
For squrae
area=side²
perimiter=4(side)
for circle
area=pir²
circumference=2pir
side=diameter, diameter/2=radius=side/2
find area not covered
that is areasquare-areacircle
areasquare=26²=676 sqauare inches
areaciecle, diameter=side, 26/2=13, area=pi13²=169*3.14=530.66 square inches
areanotcovered=676-530.66=145.34 square inches not coverd
ratio of perimiter to circumferece
perimiter=4*26=104
circumference=2pir=2pi13=26pi=26*3.14=81.64
circumference to perimiter is 81.64/104=0.785
Answer:
C. 
Step-by-step explanation:
Angle 6 and angle with measure 45° are vertical angles (opposite angles whan two lines intersect). By Vertical Angles Theorem, vertical angles are congruent, so

Angle 6 and angle with measure
are the same side interior angles when two parallel lines are cut by transversal. The same side interior angles add up to 180°, then
Area of a square is side length^2
Area = 15^ 2 = 15 x 15 = 225 square inches.
