What is 84 seconds to 8 seconds

Mathematics

1 answer:

Inessa05 [86]3 years ago

5 0

Answer:

8 out of 84: 90% decrease

200 out of 238: 16% decrease

Step-by-step explanation:

To find a percent decrease, you first subtract the end number by the initial number. This gives you the change.

ex. 84-8=76

Now you divide the change by the initial number. You'll get a decimal.

ex. 76/84=0.904...

Multiply the decimal times 100, or move the decimal to the right twice.

ex. 0.904... -> 90.4...

Now round to the nearest ones place

ex. 90.4 -> 90%

What is the value of the expression 3+2x (with an exponent of 3 on top of x) when x = 2?

Ivan

Answer:

A. 67

Step-by-step explanation:

3+2(2)^3

The first thing you would do is distribute the 2 and you would get

3+(4)^3

The next thing you would do is the exponent

3+(4*4*4) = 3+64

Then you would just add 3

64+3= 67

So the answer is A. 67.
