The most common triathlon distance for bicycle route is 40 kilometers.

deff fn [24]

The cycle route for the triathlon is of 26 miles

A triathlon is an athletic event which involves races which involves of swimming, cycling, and running over various distances

According to the given data,

The most common triathlon distance for Bicycle route is 40 kilometers

1 mile = 1 .6 kilometer

Now we know that 1.6 kilometer is 1 mile

So we are required to convert kilometers of triathlon race into miles

Therefore, 40 kilometers in mile will be= 40/1.6 = 25 miles

Hence the cycle route is of 26 miles .

Weightbof 72 books is 9 kg. what is thebweight of 80 such books?How many such books would weigh 6 kg?

ASHA 777 [7]

First, you would divide 9/72 by 72/72 and would get .125. So every book weighs .125 kg.

Then, to find how much 80 book weigh, you multiply 80 times .125 and get 10.

Lastly, to find how many books weigh 6 kg you, keep multiplying .125 by a number until you reach 6 kg. In this case the number is 48. So 48 books weigh 6 kg.

Hope this helped! ;D

Identify which equation represents a line perpendicular to the given equation 2x+5y=25

Sonja [21]

Answer:

y = 5/2x + 5

y = 5/2x - 9.5

Step-by-step explanation:

We need to solve for the y in the expresion of 2x + 5y = 25

$2x + 5y = 25\\y = (25 - 2x)/5 \\y = 5 - 2/5x$

now we re-arrenge the factors in the form y = ax + b

y = -2/5x + 5

we reverse "a"

y = 5/2 + a

And now, we use a point in the other formula to solve for a:

original line:

y = 5 - 2/5x

X = 0 then Y = 5

now we solve for the general equation of the perpendicular equation:

$y - y_1 = m ( x - x_1)$

$y - 5 = 5/2 (x - 0)\\y = 5/2x + 5$

If we use a different point we get a different formula:

original line:

y = 5 - 2/5x

X = 5 then Y = 3

$y - 3 = \frac{5}{2}(x - 5)\\y - 3 = \frac{5}{2}x -12.5 \\y = \frac{5}{2}x - 9.5$

Jayden earned some money doing odd jobs last summer and put it in a savings account that earns 12% interest compounded monthly.

aivan3 [116]

Answer:

$220.18

Step-by-step explanation:

The amount A(n) accrued for P dollars saved at r% annual interest for a period of n years compounded k times is derived using the formula:

$A(n)=P \left(1+\dfrac{r}{k}\right)^{nk}$

In Jayden's case:

A(n)=$400
r=12%=0.12
n=5 years
k=12 Months

We want to determine the amount Jayden put in the savings account.

$400=P \left(1+\dfrac{0.12}{12}\right)^{12*5}\\400=P \left(1+0.01}\right)^{60}\\400=P \left(1.01}\right)^{60}\\P=\dfrac{400}{\left(1.01}\right)^{60}}\\$

$P=\$220.18$

Jayden earned $220.18 from doing odd jobs.
