Answer:

19%

Step-by-step explanation:

The first discount is the 10% off.

An item costs 100% of its original price. By discounting 10%, the discounted price is now only 90% of the original price.

The price is now 90% of the original price. This is before the coupon is used.

Now we use the coupon. The coupon is 10% off of the discounted price.

That means now you will pay 90% of the discounted price.

The discounted price is 90% of the original price, so after the 10% coupon, you pay 90% of 90% of the original price.

90% * 90% = 0.90 * 0.90 = 0.81 = 81%

After the discount and the coupon, you pay 81% of the original price.

The price before the discount and the coupon was 100% of the original price.

Now the price is 81% of the original price.

100% - 81% = 19%

The final price has a total percent of discount of 19%.

5x² + |x+1| > 0
5x² + x + 1 > 0
x+1 > 0 because it came from absolute
5x² > 0 because it’s squared

When you try a number you should put it in the original equality
5x² + |x+1|

PLEASE MAKE SURE HELP ME!

Answer:

1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)

2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal

3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.

Plz answer last question and im lost!

Answer:

$\pi$ radian

Step-by-step explanation:

We know that angle for a full circle is 2 $\pi$

In the given figure shape is semicircle

hence,

angle for semicircle will be half of angle of full circle

thus, angle for given figure = half of angle for a full circle = 1/2 * 2 $\pi$ = $\pi$

Thus, answer is $\pi$ radian

alternatively, we also know that angle for a straight line is 180 degrees

and 180 degrees is same as $\pi$ radian.
