15.99×8/100=1.28$ this is the tax
to get the total cost 15.99+1.28= 17.27$

Please solve<br> 8.722÷(−3.56)

melomori [17]

Answer:

-2.45

Step-by-step explanation:

You are asked to EVALUATE 8.722÷(−3.56). Here you are dividing a positive number by a negative one, and so you expect that the result (quotient) will be negative.

Thus, 8.722÷(−3.56) becomes -8.722÷(3.56) = -2.45

Find the unknown side length, x. Write your answer in simplest radical form

mixer [17]

Answer:

Answer choice C

Step-by-step explanation:

By the Pythagorean Theorem, the square of the length of the hypotenuse is equal to the sum of the squares of the legs. You can rearrange this to find one of the legs using the other two sides of the right triangle:

$x=\sqrt{24^2-10^2}=\sqrt{576-100}=\sqrt{476}=\sqrt{2^2\cdot 119}=2\sqrt{119}$

Therefore, the correct answer is choice C. Hope this helps!

The heart rate of 10 adults is measured and the results are 83, 87, 90, 92, 93, 100, 104, 111, 115, 121. Find the interquartile

zloy xaker [14]

The interquartile range of the data set is 21.

Given that the heart rate of 10 adults is measured and the results are 83, 87, 90, 92, 93, 100, 104, 111, 115, 121.

The interquartile range shows the extent of the middle half of the distribution. Quartiles segment any distribution, ordered from low to high, into four equal parts. The interquartile range (IQR) contains the second and third interquartile ranges, the central half of the dataset.

The value of quartile 1 is Q₁=90

The value of quartile 3 is Q₃=111

So, the interquartile range is

IQR=Q₃-Q₁

IQR=111-90

IQR=21

Hence, the interquartile range of the data set 83, 87, 90, 92, 93, 100, 104, 111, 115, 121 is 21.

The given line passes through the points (0, -3) and (2, 3).

rodikova [14]

Answer:

y + 1 = 3( x + 1)

Step-by-step explanation:

We are asked to find the equation of the line in point-slope form

Step 1 : find the slope using the two points given

( 0 , -3) ( 2,3)

m = (y_2 - y_1) / (x _2 - x_1)

x_1 = 0

y_1 = -3

x_2 = 2

y_2 = 3

Insert the values into

m = 3 - (-3) / 2 - 0

m = 3 +3 / 2 - 0

= 6/2

= 3

Step 2: it was given in the question that the parallel to a given line and passes through ( -1 , -1)

Substitute the point into the equation

y - y_1 = m ( x - x _1)

m = 3

y - y_1 = 3 ( x - x_1)

x_1 = -1

y_1 = -1

y - (-1) = 3( x - (-1)

y +1 = 3 ( x + 1)

We don't need to open the bracket because we are asked to give the answer in a point-slope form

The equation of the line in point slope form is

y + 1 = 3( x + 1)
