The price of the product decreased by 10%and then decreased by 20% . calculate total percentage change between the final and ini

aev [14]

What is percentage change?

By quantifying the difference between two numbers and expressing it as an increase or decrease, the Percentage Change Calculator (percent change calculator) may determine the percentage change.

The initial price $V_{1}$ (100%) was decreased by 10%., then this reduced price is reduced more by 20% that becomes the final price $V_{2}$ which is 72.

Calculate percentage change from $V_{1}=100$ to $V_{2}=72$ .

= $& \frac{\left(V_{2}-V_{1}\right)}{\left|V_{1}\right|} \times 100 \\$

$=& \frac{(72-100)}{|100|} \times 100 \\$

$=& \frac{-28}{100} \times 100 \\$

$=&-0.28 \times 100 \\$

$=&-28 \% \text { change } \\$

$=& 28 \% \text { decrease }$

Rancho middle school has an average of 23 3/8 students per teacher.write this mixed number as a decimal.

Answer:

$23\frac{3}{8} = 23.375$

Step-by-step explanation:

Given:

The given mixed number is $23\frac{3}{8}$

We need to write the given mixed number as a decimal.

So, we find the decimal number by separating the parts.

$=23+\frac{3}{8}$

The value of $\frac{3}{8}=0.375$

$=23+0.375$

$=23.375$

Therefore, the decimal number of given mixed number is $=23.375$

What are the remaining angle measures if the figure is to be a parallelogram

antoniya [11.8K]

Answer: b=101 c=79 d=101

Step-by-step explanation:

since it is a parallelogram opposite angels are congruent a = c ad b=d

because we know a=79 c must equal 79

and because all the angles must add up to 360 add 79+79 = 158

then subtract from 360- 158= 202 then divide by 2 and this will give us the value for b and d b,d=101
