Answer: 25%
Step-by-step explanation: So first make the number of people who ran the marathon and the number of people who finished the marathon into a ratio
1200:4800
then make that into a fraction, 1200/4800
then make the percent of people who reached the marathon into a fraction, using 100 as the denominator and a variable as the numerator.
for example. p/100 (p, represents the percent)
then cross multiply.
1200x100=1200000
Last divide 1200000 by 4800 to get 25%.
Answer:
5x + y - 2 + 3 - 1
Step-by-step explanation:
The perimeter when 96 triangles are put together in the pattern shown below will be 98cm
Find the required triangle attached
In the diagram shown, we can see that we have 5 triangles.
The first thing we need to do is add one more triangle to have, six triangles,
Perimeter of the resulting 6 triangles = 6 + 2 = 8cm
For 8 triangles;
Perimter = 8 + 2 = 10cm
For "n" triangles;
Perimeter of n triangles = n + 2
Hence if 96 triangles are put together in the pattern shown below, hence
n = 96
Perimeter of the 96 triangles = 96 + 2
Perimeter of the 96 triangles = 98 cm
Hence the perimeter when 96 triangles are put together in the pattern shown below will be 98cm

Weird that the only choices are given as integrals with respect to

. (Integration along the

axis would be way easier, but whatever)
The fourth option should do it.
