Answer:
144 total cookies
Step-by-step explanation:
First, set up a proportion to find out how many red cookies there are. 4 over 5 is equal to x over 80. Cross-multiply and you will get 64 red cookies. This question is asking how many total cookies there are, so you would add the red and yellow cookies together. 64 plus 80 is 144 total cookies.
Answer:
13 cm
Step-by-step explanation:
To find the answer, you can use the formula to calculate the volume of a cone and isolate the height:
V= πr^2
V= volume= 218 cubic centimeters
π= 3.14
r= radius= 4 cm
h=height
218= 3.14*4^2*
218*3=3.14*16*h
654=50.24*h
h=654/50.24
h=13
According to this, the height of the container is 13 cm.
Answer:w= 25
Step-by-step explanation:
Cost of bottle of water = (w-1)cents
Cost of bottle of milk = (2w-11)cents
Let x bottles of water cost $4.80= 480 cents
Also,x bottles of milk cost $7.80= 780 cents
x(w-1)= 480
x(2w-11) = 780
x = 480/w-1 = 780/2w-11
960w -5280= 780w-780
180w = 4500
w= 25
