Answer:
8100 Hours
Step-by-step explanation:
We all have heard of miles per hour, so just plug that formula into the question!
Ex. 18 miles PER HOUR x 450 MILES = 8100 hours
Hope this helps!
Perimeter is the sum of all a shapes sides.
with that in mind, we know a rectangle has four sides. with 2 pairs being the same.
The length as told is, 5 centimeters less than two times the width. Two times the width would be 2w and five less than that would be minus five. so the length is 2w - 5
now to find the perimeter we do two times the width + two times the length.
2w + 2(2w -5) = 80.
Distribute: 2w + 4w - 10 = 80
Add ten to both sides and combine the 2w & 4w:
6w = 90
Divide both sides by 6: w = 15.
with this we know the width is 15. to find length plug in 15 to the 2w - 5 equation.
2(15) - 5 = 30 - 5 = 25.
Slap on the units and width = 15 cm, length = 25 cm
Answer:
(2,-2)
(10,-10)
(2,-9)
(7,-10)
Step-by-step explanation:
The given point is (2,-10)
This point is in the fourth quadrant.
To be able to use the number line to find the distance between this point , (2,-10) and another point in the fourth quadrant, the second point must have the same x-coordinate with this point or the same y-coordinate with this point.
9 and 2/4 can be written as 9.5 in decimals. We usually round 5 up, so we would round it to 10.
if it was 9.4 we would round it down to 9.
