Answer:
The speed of car in miles per minute is
miles per minute and
The speed of car in mile per hour is 40 miles per hour,
Step-by-step explanation:
Given as :
The distance cover by car = 2
=
miles
The Time taken by car to cover distance = 3
min =
min
The speed o car in miles per minute = S miles/min
So, Speed = 
Or, S =
mie per min
∴ S =
miles per minute
Now, Let The speed of car in miles per hour = x miles/h
So, Time in hour =
×
=
hours
So , Speed = 
Or, x =
miles per hours
Or, x = 40 miles per hours
Hence The speed of car in miles per minute is
miles per minute and the speed of car in mile per hour is 40 miles per hour, answer
Answer:
Step-by-step explanation:
The two dots on the bottom of this figure define the base of a triangle. If we now use a compass to draw the blue arcs on either side, as shown, the arcs will intersect at two points. A straight line drawn through these two points will be perpendicular to the base. The triangle will be isosceles and could be (but doesn't have to be) equilateral.
40(12.62) + 7(12.62(1.5)) = 504.80 + 7(18.93) = 504.80 + 132.51 =
637.31 <===
Answer:
a) 7/4 b) 15/2
Step-by-step explanation:
a) Scale Factor = Image / Object
Take the side of Triangle ABC that's BC Why? Because it corresponds with the Image Triangle ADE's DE
= 21/12 = 7/4
b) 7/4 = 10+ x / 10
Cross Multiply
= 4 ( 10 + x ) = 70
= 40 + 4x = 70
= 4x = 70-40
= 4x = 30
= 4x/4 = 30/4
x = 15/2
