Step-by-step explanation:
a+b+c=180°
64°+b+c=180°
b=c
2b+64°=180°
2b=180-64
2b=116°
b=116/2
b=58°=c
Answer:
35 square units.
Step-by-step explanation:
To find the area of a parallelogram, the formula is the exact same as finding the area of a rectangle. So 7 x 5 is 35.
Answer:1.5
+ 15

2.25r
Step-by-step explanation:
You can try that!
Answer:
1.) Slope Formula:
y2 - y1
———
x2 - x1
2.) Slope-Intercept Form:
y = mx + b
3.) Standard Form:
Ax + By = C
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx
where
k is the constant of proportionality
Verify each table
table a
Let
x ----> distance
y ----> sound level
For each ordered pair calculate the value of k
k=y/x
so
(5,85) -----> k=85/5=17
(10,79) ----> k=79/10=7.9
the values of k are differents
that means
the table nor represent a proportional relationship
table b
let
x ----> volume
y ----> cost
k=y/x
(16,1.49) ----> k=1.49/16=0.093125
(20,1.59) ----> k=1.59/20=0.0795
the values of k are differents
that means
the table nor represent a proportional relationship
