For this case we have to, so that both runners finish at the same time, Dave must also reach 88 seconds.
With respect to the times we have:
Dave must have a 33-second disadvantage.
This means that in those 33 seconds of difference Jack runs:
So, Dave must lose 165 yards to get to Jack
Answer:
165
Answer: x=-3
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
3x - 10x + 5 = 5x + 17 (collect like terms)
-7x + 5 = 5x + 17 (subtract 5x on both sides)
-12x + 5 = 17 ( subtract 5 on each side)
-12x = 12 ( divide by -12 on each side)
x = -1
Answer:
40
Step-by-step explanation:
Divide 30 by 3 to find 1/4. You get 10.
Multiply 10 by 4 to find 4/4. You get 40.
Answer:
43.8
Step-by-step explanation:
Remark
Are there ever a lot of assumptions!!
- The rectangles are all the same size
- the triangles are the same size
- The rectangles are indeed rectangles.
- The triangles are isosceles.
- The two equal sides are both equal to the width of the rectangles.
Area of the rectangles
A = L * W
L = 4 m
W = 3 m
Area = 4*3 = 12
There are 3 rectangles so the total area = 3*12 = 36
Area triangles
Area = 1/2 b * h
b = 3
h = 2.6
Area = 1/2 * 2.6 * 3
Area = 1/2 7.8
But there are 2 of them so the area for the 2 is
Area = 2* 1/2 7.8
Area = 7.8
Total area = 36 + 7.8
Total area = 43.8
