Answer:
25 yards
Step-by-step explanation:
A parallelogram is a quadrilateral (a four sided object) with parallel sides
Some of the characteristics of a parallelogram includes :
- Opposite sides and angles are congruent .
- Opposite angels are congruent (D = B).
- Consecutive angles are supplementary (A + D = 180°).
- The diagonals bisect each other
Area of a parallelogram = base x height
Area = 525
base = 21 yards
height = ?
525 = 21 x height
divide both sides of the equation by 21 to find the value of the height
525 / 21 = height
height = 25 yards
Answer:
Input variable x: Number of classes he attends.
Output variable y: Monthly cost
Slope: Cost per class, of $2
y-intercept: Membership fee, of $25.
Function: 
Step-by-step explanation:
This situation can be represented by a function is the following format:
In which y is the monthly cost(output), m is the cost per class(slope), x is the number of classes he attends(input) and b is the membership fee(y-intercept).
We have that:
There is a membership fee of $25 per month and a fee of $2 per workout class he attends.
This means that 
. So
D = M/V where M=mass and V = volume
Assume the Mass is 1 kg and the Volume = 1 cm³, so d= 1/1 kg/cm³
for V=0.1 → d = 1/0.1 = 10 kg.cm³
for V = 0.01 → d = 100.kg.cm³
for V = 0.001 → d = 1000.kg.cm³
for V = 0.000001 → d = 1,000,000.kg.cm³
and when Volume → 0. density →∞
.
Answer:
12
Step-by-step explanation:
7 times 12 is 84. 4 times 21 is 84. The digits have a sum of 3.
A, because:
Hardcover: 0.35
Buys hard cover and non-fiction: 0.35 x 0.55 = 0.1925
