Answer:
Step-by-step explanation:
we know that
The sides of a rhombus are all congruent and the diagonals are perpendicular bisectors of each other
so
Applying the Pythagorean Theorem
where
c is the length side of the rhombus
a and b are the semi-diagonals
we have
substitute the values
To find out the perimeter of the rhombus multiply the length side by 4
Well,
If the length of the legs of the second triangle are proportional to the lengths of the legs of the first triangle, we could simply multiply both of the dimensions by whole numbers and get an infinite number of proportional lengths.
Example:
4.5 * 2 = 9
1.5 * 2 = 3
A triangle with legs measuring 9 meters and 3 meters will be proportional to the first triangle with leg lengths of 4.5 and 1.5 meters, respectively.
More proportional lengths:
4.5 * 3 = 13.5
1.5 * 3 = 4.5
4.5 * 4 = 18
1.5 * 4 = 6
Answer:
<u>Option A. about 1 seconds</u>
Step-by-step explanation:
Let the initial speed u and the final speed v
Time t , distance s and acceleration of gravity g
The equation of motion are:
v = u + gt ⇒(1)
s = ut + 0.5 gt² ⇒(2)
v² = u² + 2gs ⇒(3)
Marques drops a plate from a height of 5 feet.
So, u = 0 , s = 5 ft , g = 9.8 m/sec²
Substitute at (2)
s = ut + 0.5 gt²
5 = 0 * t + 0.5 * 10 * t²
∴ t² = 5/(0.5*9.8) = 1.02
∴ t = √1.02 = 1.01 seconds ≈ 1 seconds (to the nearest integer)
<u>The answer is option A. about 1 seconds</u>
Answer:
The answer to the question is
Shawn has to wait for 3 minutes for Jason to meet him at 2 miles away from the station
Step-by-step explanation:
To solve the question, we note the variables
Bike speed = 20 mph
Start point of Jason = 1 mile away from the station
Starting point of Shawn = 2 mile away from the station
Total miles away from station = y
Direction of biking = away from the station
Therefore if they both start biking at the same time, Shawn is ahead of Jason
Riding speed of Shawn = Riding speed of Jason = 20 mph
That is Shawn has to wait for 1/20 hr or 3 minutes for Jason to meet him at 2 miles away from the station
I assume you're using American notation and this number is equal to 932805 (European notation) : then 9 represents 900 000, which is 9 hundred thousand: so 9 s in <span>b. The hundred-thousands place.
(In the European notation it would in in the hundreds place).</span>
