You have a 20 % total purchase coupon . You total is $134.22 if you use the coupon what does your total is $134.22 if you use th

Romashka-Z-Leto [24]

Answer:

$107.38

Step-by-step explanation:

FIRST WAY:

Since you have a 20% discount, that is equivalent to two-tenths of $134.22

Step 1: find the discount.

0.2 x 134.22 = 26.844 (round to 26.84)

Now that you have the discount, simply subtract that discount from your original price.

Step 2: find the final price.

$134.22 - $26.84 = $107.38

SECOND WAY:

A faster way to solve problems like this is to find the percentage of cash you are going to pay with the coupon. To do so, simply convert your percentage value to its corresponding decimal value relative to the original.

<em>Layman's terms: just subtract the 20% from 100% to get 80%.</em>

Step 1: find the percentage to be paid.

100% - 20% = 80% OR 1 - 0.2 = 0.8

Now that you have the percentage you need to pay, just multiply that percentage by the original amount.

Step 2: find the final payment.

$134.22 x 0.8 = $107.38

Aaron is in his math class. His teacher says that class will be dismissed when the minute hand makes a 90° clockwise rotation. W

olga_2 [115]

Answer:

3:20

Step-by-step explanation:

The 360 degrees clockwise rotation of the minute hand corresponds to 60 minutes.

The 90 degrees clockwise rotation is one-fourth of the 360 degrees, and hence will corresponds to 15 minutes.

The time is now 3:05.

After 15 minutes the time will be 3:20

Therefore the teacher dismisses the class at 3:20

One method for estimating abundance of animals is known as line-intercept sampling. The theory of this method, when applied to A

Kruka [31]

Answer:

0.6848

Step-by-step explanation:

Mean of \hat{p} = 0.453

Answer = 0.453

Standard deviation of \hat{p} :

= \sqrt{\frac{\hat{p}(1-\hat{p})}{n}} = \sqrt{\frac{0.453(1-0.453)}{100}} = 0.0498

Answer = 0.0498

P(0.0453 - 0.05 < p < 0.0453 + 0.05)

On standardising,

= P(\frac{0.0453-0.05-0.0453}{0.0498} <Z<\frac{0.0453+0.05-0.0453}{0.0498})

= P(-1.0044 < Z < 1.0044) = 0.6848

Answer = 0.6848

Her horizontal distance to the rim satisfies the ratio
(10 ft -6 ft)/distance = tan(25°)
so the distance is
distance = (4 ft)/tan(25°) ≈ 9 ft
