Answer:

$15.56

Step-by-step explanation:

So start by doing a 10% tip, because you just move the decimal place over by 1, so $1.35, and then divide that by 2 to get 5% which is .68, and add them to get 2.03. You can get the same answer by multiplying 0.15 to 13.53. 13.53 + 2.03 is 15.56. Hope this helped and have an awesome day!

Ahmad travelled 1/4 of a journey by Train X, 3/4 of the remainder by Train Y and the remaining 10km by Train Z. a) How far did A

sveta [45]

Hey there! I'm happy to help!

Train X takes out 1/4 of our journey.

Now, we have 3/4 of the journey left.

Train Y takes 3/4 of the last 3/4 of the journey. How much is that, let's just multiply the fractions!

3/4*3/4= 9/16

So, 9/16 of the total journey is done by Train Y.

A fourth of 16/16 is 4/16, so that leaves us with 3/16 left to go.

So, 3/16 of our total distance is equal to 10 km. Let's call our total distance d and set this up as an equation.

3/16d=10

Divide both sides by 3/16.

d= 53 1/3

We also remember that Train Y gave us 9/16 of our total journey, so we can multiply this by our total distance to see how far train Y went.

53 1/3 * 9/16= 30

So, A. Ahmad traveled 30 miles by Train Y and B. his total distance traveled is 53 1/3 miles.

Have a wonderful day and keep on learning! :D

Joan has earned grades of 88, 94, 92, and 98 on math tests so far. What must her next grade be to give her an average grade of 6

Ira Lisetskai [31]

Answer:

see the explanation

Step-by-step explanation:

Let

x ------> the next grade

we know that

To find the average grade sum the grades by the number of math test

so

$60=\frac{(88+94+92+98+x)}{5}$

solve for x

Combine liker terms in the right side

$60=\frac{(372+x)}{5}$

Multiply by 5 both sides

$300=372+x$

Subtract 372 both sides

$300=372+x$

$x=-72$ -----> this is not make sense

The grade cannot be a negative number

so

For x=0

The minimum average grade is

$\frac{(372)}{5}=74.4$
