(3 x .1) + (4 x .01)
x is multiplication

Since the 3 is in the tenths place, multiply by 1 tenth, same with the hundredths place, just multiply 4 by 1 hundredth

Answer:

0.340=3 \times 0.10 + 4 \times 0.01

Step-by-step explanation:

Expanded notation refers to write a number showing the value of each digit. Hundreds units are multiplied by 100, tens by 10, units by 1, tenths by 0.10, hundredths by 0.01 and thousandths by 0.001.

So, the given number is 0.340 and the expanded notation is

0.340=3 \times 0.10 + 4 \times 0.01

Observe that each digit was multiplied by its value given by its position.

This question is confusing me
gizmo_the_mogwai [7]

Answer:

She went on the slide 8 times and on the roller coaster 4 times

Step-by-step explanation:

We convert each statements to a mathematical equation.

Firstly, let's represent the number of times she went on the coaster with R and the number of times on the slide with S. We know quite well she went on 12 rides. Hence the summation of both number of times yield 12.

Mathematically, R + S = 12. ........(i)

Now we also know her total wait time was 3hours. Since an hour equals 60 minutes, her total wait time would equal 180 minutes.

To get a mathematical representation for the wait time, we multiply the number of roller coaster rides by 25 and that of the slides by 10.

Mathematically, 25R + 10S = 180 .......(ii)

Here we now have two equations that we can solve simultaneously.

From equation 1 we can say R = 12 - S. We can then substitute this into equation 2 to yield the following:

25(12 - s) + 10s = 180

300 - 25s + 10s = 180

300 - 25s + 10s = 180

300 - 15s = 180

15s = 300 - 180

15s = 120

S = 120/15

S = 8

S = 8 , and R = 12 - S = 12 - 8 = 4
