Each 7 inches of the tv are equal to one inch of the phone. Therefore Divide 56 by 7 you get 8 56/7=8
Answer:
a
Step-by-step explanation:
Cylinders:
Ratio of radii = 1 : 4
Radius of two cylinders are: r , 4r
Ratio of height = 3 :1
Height of two cylinders are: 3h , h
Lateral surface area of cylinder = 2πrh
Ratio of lateral surface area= 2π* r * 3h : 2π* 4r * h
= 3 : 4

_______
Answer:
The answers that apply are A (x=-2) and C (x=1),
____________________
Step-by-step explanation:
Actually , x= -2 apply because
If you look at the graph you will see that f(-2)=1.
See the point with coordinates (-2 , 1).

ANSWER
Period: 2π , amplitude: 4
EXPLANATION
The graphed function is
The amplitude of this function is
The period is 2π because there is no phase shift hence the period is still equal to the parent function.
Period: 2π , amplitude: 4
Let the number of quarter be x and that of nickels be y
total number of coins will be:
x+y=85
thus
x=85-y.........i
total amount of money will be:
0.25x+0.05y=14.25....ii
substituting i in ii we get:
0.25(85-y)+0.05y=14.25
21.25-0.25y+0.05y=14.25
7=0.2y
y=7/0.02
y=35
thus
x=85-35=50
the number of quarters was 50 and that of nickels was 35
