Answer:

12 miles

Step-by-step explanation:

Alyssa takes part in the triathlon. She cycles 4/5 of the route, runs 1/8 of the route, and swims the rest of the way. She swims 0.9 miles. Find the total distance of the triathlon route.

Total distance Alyssa cycled and ran =

\frac{4}{5} + \frac{1}{8}

\frac{32 + 5}{40} = \frac{37}{40}

Distance she swam =  1 - 37/40 = 3/40

3/40 of the distance is 0.9

the total distance = 40/3 x 0.9 = 12 miles

What is ✔️16 ? Raises cuadrada
aev [14]
If you are looking for √16, you are looking for the square root of 16. The square root of a number is defined by what number multiplied by itself will get you.
x^2 (a number squared) = 16.
√16 = x.
Let's try from numbers 1-5 for a square.
1x1 = 1
2x2 = 4
3x3 = 9
4x4 = 16
√16 = 4.
I hope this helps!

What represents the equal number of parts that equal a whole in a fraction.
Alex
This refers to the "denominator" of a fraction. By definition, the denominator tells you how many you need to have of an equal part in order to create a whole. The numerator tells you how much of those equal parts you have.

For which value of a does the following system of equations have no solution? -x+6y=7 , -5x+10ay=32
dlinn [17]

Remark

If the lines are parallel, there are no solutions to the system of equations. Start with the equation you know the most about.

x + 6y = 7                Subtract x from both sides

x - x + 6y = 7 - x      Combine

6y =  - x + 7             Switch and divide by 6

y = -x / 6 + 7/6

The general equation for a line is y = mx + b where m is the slope of the line.

m = - 1/6

================

Now look at the second equation

10ay - 5x = 32               Add 5x to both sides

10ay = 5x + 32              Divide by 10a

y = (5/10a)x + 32/(10a)  

===============

Now you must make

5/10a = - 1/6                     Cross Multiply

5* 6 = - 10a * 1

30 = - 10a                        Divide by - 10

a = 30 / - 10

a = - 3

So these two equations will have no solution when a = - 3
