First of all, remember if 2 people are walking away from each other at the same speed (ex 4 mph), after 1 mile, they would be 8 miles away. 4 miles south and north. So these trains go away from each other at a total of 150 mph( 67 + 83). So your equation is h = hours, 150h = 600. Divide both sides by 150 to get h = 4. 4 hours is your answer.
Answer:
2x-9y
when you add 2 and 7 it's 9, so add the y, then 4-2 which is 2, add an x.
2x-9y
Answer:
544 units²
Step-by-step explanation:
The surface area is the sum of the areas of the three rectangular faces and the two triangular bases.
SA = 10×14 +10×14 +12×14 + 2(1/2)(12)(8)
= 14×(10+10+12) +12×8
= 448 +96
= 544 . . . . square units
_____
The area of a rectangle is the product of its dimensions:
A = LW
The area of a triangle is half the product of its base and height:
A = (1/2)bh
Here, both triangles have the same area, so we multiplied the area of one of them by 2 to get the area of both of them.
Youre answer is D. Giving responsibility for part of a company’s work to another company ....
Answer:
(x, y) = (15, 4)
Step-by-step explanation:
Segments created by parallel bases of the triangle(s) are proportional.
We observe that the lower segment is 1/3 the length of the upper segment.
5 = 1/3x
15 = x . . . . . . multiply by 3
__
y = (1/3)(12)
y = 4
