The correct question is
<span>Sandra needs to buy 21/25 meters of chain for a home project. Which decimal number is equal to the fraction 21/25?
we have that
21/25--------> multiply by (4/4)
(21/25)*(4/4)=(21*4)/(25*4)-----> 84/100------> 0.84
the answer is the option
0.84

Answer:
15
Step-by-step explanation:
3/5 = wooden
2/5 = mechanical
Answer:
7*14=98 and another 7 cant into it or it will be over 100 so there will be 2 cubes left over.
Step-by-step explanation:
C is a function. X cannot repeat itself more than once, that will make it not a function. For example 1,1, 1,2, 1,3 x repeats itself 3 times that is NOT a function. Y can repeat itself more than once but X cannot.
Answer:
Equation of the circle =
80 = ( x - 1)^2 + (y + 1)^2
Step-by-step explanation:
Center = (1 , -1)
Point = ( 5 , 7)
Eqn of a circle is
r^2 = (x - h)^2 + (y - k)^2
We are not given the radius of the circle, fortunately we are provided the information that the circle contains a point ( 5, 7), so we use the above information to find r
Using the center (1, -1)
h - 1
k - -1
r^2 = (x - 1)^2 + ( y - -1)^2
r^2 = (x - 1)^2 + (y + 1)^2
With the point ( 5,7)
x = 5
y = 7
r^2 = ( 5 - 1)^2 + ( 7 + 1)^2
= 4^2 + 8^2
= 16 + 64
= 80
r^2 = 80
r = square root of 80
r = 8.94
The r = 8.94 , which means the equation of the circle is
80 = (x - 1)^2 + ( y + 1)^2
