Mathematics

Anika [276]3 years ago
4 0

20 * .10 = 2  <em>(2 = 10% of 20)</em>

20 + 2 = 22

20 x .07 = 1.4  <em>(1.4 = 7% of 20)</em>

20 + 1.4 = 21.4

The price of a 20$ haircut with a 10% tax would be $22.

The price of a 20$ haircut with a 7% tax would be $21.40.

The ratio of the muffins Baker A baked to the number of muffins Baker B baked was 8 : 5. The ratio of the number of muffins Bake
Ksju [112]

Answer:

170 muffins

Step-by-step explanation:

We start from the ratio between baker B and C

The ratio of cakes baked by both is 4:3.

We know baker C baker 150 muffins:

This mathematically means:

B:C = 4:3 = B:150

This means 4/3 = B/150

B = (4 * 150)/3 = 200

Baker B baked 200 cakes

We now move back to the first statement

The ratio between baker A and B is 8:5

Mathematically, this means:

A:B = 8:5 = A:200

8/5 = A/200

A = (8 * 200)/5 = 320

The number of cakes baker A baker pass baker C would be 320 - 150 = 170 muffins

Mumz [18]
The digit 3 is in the millions place value, hence it is worth three million, not three thousand.
Therefore, 3,000,146 should be read as three million, one hundred and forty-six, and NOT three thousand, one hundred and forty-six.
Hope this answer helps you! If it did, please mark it as the brainiest! I would really appreciate it! :)

So in my math homework lesson today we are learning “Solve One-Step Problems”. I don’t completely understand how to do it. I was
Sedaia [141]

Answer:

Step-by-step explanation:

So, in this problem, we're given the size of the of the file. We are also given the rate of change of the amount-downloaded function.

Notice how the transfer rate is in units of time (25.2 MB/s means 25.2 MB per second).

If we want to calculate how <em>long</em> it'll take to download the entire file, we have to divide the file size by the amount of the MB downloaded in one second. (This is assuming the download rate is constant, in the case it isn't constant, you would use calculus) This will find the total number of seconds needed to download the entire file.

We're essentially solving for t in the equation

400.6 = 25.2t

t = \frac{400.6}{25.2} = \frac{2003}{126} = 15.897
