Answer:r=3cm,diameter =6cm and C=18.84cm
Step-by-step explanation:
To find the radius,diameter and circumference according to the diagram drawn above
r=3cm
Diameter=2×3cm
d=6cm
To find the circumference
C=2πr
C=2×3.14×3cm
C=18.84cm
Answer:
30:15 and 2 times the amount because 15x2=30
Step-by-step explanation:
Graphing it @ https://www.desmos.com/calculator , we get that f(x) clearly approaches inf at x=10 and a vertical asymptote is clearly 10
The first one is irrational because it is a repeating fraction.
the third is square root of 7 is less than 14/5
the fourth is <span>negative 5 over 6, negative 5, negative 31 over 6, negative square root 26

Answer:
The constant of proportionality is 2.5 dollar per cupcake and then the required equation would be
.
Step-by-step explanation:
Given:
Let the number of cupcakes be represent by 
Also let the total cost be represented by 
We know that two proportional quantities are in for;

where, k⇒ represents constant of proportionality.
Now we know that;
1 dozen = 12
Half dozen = 6
Now Given:
half dozen cupcakes cost $15.
So Let us substitute
and
in above equation we get;

Dividing both side by 6 we get;

Hence the constant of proportionality is 2.5 dollar per cupcake and then the required equation would be
.
