When you divide two fractions, you're actually multiplying one of them by the reciprocal of the other. First, find the reciprocal of the second fraction by flipping it upside down. Then, multiply it by the first fraction. (Numerator x numerator and denominator x denominator)
÷ 
Replace the second fraction with it's reciprocal
x 
Multiply (-7 x 3 and 12 x 2)
Both 21 and 24 are divisible by three, so divide them by 3
The ounces of cheese Ellie uses to make tacos is 2
What is a unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Calculation :
1 pound = 16 ounces
Total cheese Ellie has = pound
Cheese required to make tacos = ×
=
pounds
Ounces of cheese required to make cheese are × 16 = 2 ounces

Answer:
Volume of sphere is given by:
......[1]
where
V represents the volume of sphere
r represents the radius of the sphere.
Value of
Since, it is given that: Diameter(D) = 12.3 cm
Diameter(D) = 2r
Divide both side by 2 we get;
r = 6.15 cm
Now, substitute the value of r in [1] we get;
Simplify:
V = 973.853732 cubic cm
Therefore, the exact volume of sphere is, 974 cubic cm
Answer:
Step-by-step explanation:
Ok we have two intersections:
One point of intersection is (0,f(0)).
Another point of intersection is (A,f(A)).
Slope-intercept form of a linear equation is y=mx+b where m is the slope and b is the y-intercept.
We actually are given the y-intercept is f(0). That means b=f(0).
Now we need to calculate the slope which is rise/run or change in y over change in x.
I'm going to find the slope by lining up the points vertically and subtracting vertically, then will put 2nd difference over 1st difference.
Like so:
(A. , f(A))
-(0. , f(0))
--------------
A f(A)-f(0)
So the slope is .
We are now ready to give our answer for the linear equation in slope-intercept form.
We have and
.
Entering into y=mx+b form:
