The change that Angie will receive from an $100 bill is $38.944.

<h3>How to calculate the value?</h3>

Angie went to the store and bought 3 pairs of tennis shoes that each cost $24. The total cost will be:

= 3 × $24 = $72

Sales tax was then calculated at 6%. This will be:

= 6% × $72

= $4.32

Total cost = Cost + Tax

= $72 + $4.32

= $76.32

Coupon off = 20% × $76.32 = $15.264

Total amount paid = Cost - Coupon

= $76.32 - $15.264

= $61.056

The change gotten will be:

= $100 - $61.056

= $38.944

Consider the line given by the equation: 2x - y= -2

Klio2033 [76]

Answer:

Step-by-step explanation:

look at 2=x-y=2

move this term to the left (2)

it becomes 2=x-y+2=0

and thats your results

Examples: x^2-2x=-1, 3x-x-x+a-a=5, (x^2-1)/(x+1), 2x-(x+x)

Conference A and conference B each have 10 football teams. The table shows the number of football games that each team in the tw

babymother [125]

Answer with explanation:

1.Mean of a Data set

$=\frac{\text{Sum of all the observation}}{\text{total number of observation}}$

$=\frac{10+9+11+8+10+12+2+7+8+0+12+10+8+11+3+12+6+7+4+3}{20}\\\\=\frac{153}{20}\\\\=7.65$

2. Range = Maximum value in two conferences - Minimum value in two conference

= 12 - 0

=12

The mean number of wins for teams from the two conferences is 7.65.

The range in wins is 12.

In AOPQ, o = 700 cm, p = 840 cm and q=620 cm. Find the measure of _P to the<br> nearest degree

Westkost [7]

Given:

In triangle OPQ, o = 700 cm, p = 840 cm and q=620 cm.

To find:

The measure of angle P.

Solution:

According to the Law of Cosines:

$\cos A=\dfrac{b^2+c^2-a^2}{2bc}$

Using Law of Cosines in triangle OPQ, we get

$\cos P=\dfrac{o^2+q^2-p^2}{2oq}$

$\cos P=\dfrac{(700)^2+(620)^2-(840)^2}{2(700)(620)}$

$\cos P=\dfrac{490000+384400-705600}{868000}$

$\cos P=\dfrac{168800}{868000}$

On further simplification, we get

$\cos P=0.19447$

$P=\cos^{-1}(0.19447)$

$P=78.786236$

$P\approx 79$

Therefore, the measure of angle P is 79 degrees.
