5:15 because you aren't drawing all of the 52 cards so your proportion would be the probability of drawing at least 5 spade and the 15 cards drawn in all

AB=AD. Enter the range of values for x. 40° 14° 9x-27 108. ?
zalisa [80]

The range of values of x as shown in the diagram is -9 < x < 15

<h3>Inequality expressions</h3>

Inequality are expressions not separated by an equal sign. The required inequality expression is given as:

|9x - 27| < 108

For the positive inequality

9x - 27 < 108

9x < 108 +27

9x < 135

x < 15

For the negative inequality

-9x +  27 < 108

-9x < 108 - 27

-9x < 91

x > -9

-9 < x

Hence the range of values of x as shown in the diagram is -9 < x < 15

If A = 30° and r = 12, find x. (Round your answer to the nearest whole number.)
Margaret [11]

Answer:

\boxed{12}

Step-by-step explanation:

A = 30° and r = 12

\sin A = \frac{r}{r + x}

\sin 30 = \frac{12}{12 + x}

\frac{1}{2} = \frac{12}{12 + x}

1(12 + x) = 2(12)

12 + x = 24

x = 24 - 12

x = 12

.

An item is regularly priced at $45 . it is on sale for 60% off the regular price. how much (in dollars) is discounted from the r
wariber [46]
The discount is 60% of regular price, or we can write it as
discount = 60% × regular price

input the numbers
discount = 60% × regular price
discount = 60% × 45
discount = 60/100 × 45
discount = 2,700/100
discount = 27

The answer is $27
