Answer:
100 cm
Step-by-step explanation:
The formula to answer this question is base x height divided by 2. All you have to do is substitute: 10x20= 200 divided by 2 is 100.
The area of a parallelogram is base times height.
Multiply 16ft by 18ft.
(16)(18) = 288
The parallelogram is 288 ft².
Answer: total Distance = 60km
Time = 4.5hrs
Speed = 60/4.5
13⅓km/hr
Step-by-step explanation:
Answer:
y =
x + 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 10x + 1 ← is in slope- intercept form
with slope m = - 10
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, thus
y =
x + c ← is the partial equation
To find c substitute (5, 7) into the partial equation
7 =
+ c ⇒ c = 7 -
= 
y =
x +
← equation of line
