If the consumer price index changes from 125 in september to 150 in october, what is the rate of inflation?
allochka39001 [22]
The rate of inflation is analogous to the percent difference of the original to the new price. Thus, its formula is written as:

Rate of Inflation = [New price - Base price]/Base Price * 100
Rate of inflation = (150 - 125)/125 * 100 = 20%

<em>So, the answer is A.</em>

In circle P with mNRQ = 60°, find the angle measure of minor arc NQ
Galina-37 [17]

Given:

m∠NRQ = 60°

To find:

The angle measure of minor arc NQ

Solution:

The inscribed angle is half of the intercepted arc.

$\Rightarrow m\angle NRQ =\frac{1}{2} m(ar NQ)

Multiply by 2 on both sides.

$\Rightarrow 2 \times m\angle NRQ =2 \times \frac{1}{2} m(ar NQ)

$\Rightarrow 2 \ m\angle NRQ =m(ar NQ)

Substitute m∠NRQ = 60°.

$\Rightarrow 2\times 60^\circ=m(ar NQ)

$\Rightarrow 120^\circ=m(ar NQ)

The measure of minor arc NQ is 120°.

PLEASE HELP!!!!
3241004551 [841]

Answer: Correct

Step-by-step explanation:

The conclusion is valid. Since \overline{AB} \parallel \overline{DC} and \overline{AD} \parallel \overline{BC}, we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since \overline{AB} \cong \overline{BC}, we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.
