Answer: Length = 642 cm
Concept:
Here, we need to know the idea of how to find the area of a rectangle.
Area (rectangle) = l × w
l = length
w = width
Solve:
<u>Given information</u>
A = 24396 cm²
w = 38 cm
<u>Given expression</u>
A = l × w
<u>Substitute values into the expression</u>
24396 = l × (38)
<u>Divide both sides by 38</u>
24396 / 38 = l × 38 / 38
Hope this helps!! :)

Answer: 35 m
Step-by-step explanation:
The problem is the same as:
a man is fix (not moving) and the goods train is travelling at the speed of 54+72 = 126 (km/h)
Distance = 126 km/h* 8 s=126000 m/(3600 s) * 8 s=35 m
9514 1404 393
Answer:
Step-by-step explanation:
In order to solve this, we need to assume that the angles involving x are supplementary, and the angles involving y are complementary.
(7x -8) +(13x -32) = 180
20x -40 = 180 . . . . . . . . . collect terms
20x = 220 . . . . . . . . . add 40
x = 11 . . . . . . . . . . divide by 20
__
(10y +22) +(7y) = 90
17y = 68 . . . . . . . . . . . . collect terms, subtract 22
y = 4 . . . . . . . . . . divide by 17
Just find the interest paid after one year, and then multiply the result by 6 (years). This gives you the amount of simple interest.
The easiest approach would be to use the formula i = p r t. In this case p = $600, r = 0.04, and t = 6 years.
