Answer:
Part a) 
Part b) 
Step-by-step explanation:
Part a)
Let
x -----> the number of weeks
y ----> the total amount Chem has deposited in a saving account
we know that
The equation of a line in slope intercept form is
where
m is the rate or slope of the linear equation
b is the y-intercept of the linear equation or initial value (value of y when the value of x is equal to zero)
In this problem we have that
The rate or slope is equal to
-----> amount deposited by Chem each week
The y-intercept or initial value is
----> amount deposited originally in the saving account
substitute the values
Part b) How much has Chem deposited 30 weeks after his initial deposit?
For x=30 weeks
substitute in the equation
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
First, you would get the decimal form of 67% by moving the decimal (At the end of most whole numbers.) over two, giving you .67.
Next, multiply 296 by this new decimal- .67*296=198.32.
There you go! : )
Answer:
∠F = 50°
Step-by-step explanation:
The sum of all three angles in a triangle = 180°
∠F = 180° - 30° - 100° = 50°
