You want to buy some clothing from an online retailer. The shirts cost $9 each and the
alisha [4.7K]

The answer is $73

Explanation:

since you are buying five shirts for nine dollars each you would need to do 5x9 which equals 45. Now you need to do 12x2 since you bought two pairs of pants for twelve dollars each. 12x2 equals 24. Now you need to add 24 and 45 to see what your price is. 24+45=69. Now add on four dollars for shipping and handling and you will have $73 dollars. Hope this helps!

Find the total perimeter of the kite shown below. round to the nearest tenth . pleas use step by step instructions.
guapka [62]

Answer: B. 25.2 units

Step-by-step explanation:

The kite consists of 4 right angle triangles. The two smaller right angles are equal. Also, the two bigger right angles are equal.

To determine the hypotenuse of each triangle, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Considering the smaller triangle,

Hypotenuse² = 4² + 3² = 16 + 9 = 25

Hypotenuse = √25 = 5

Considering the smaller triangle,

Hypotenuse² = 7² + 3² = 49 + 9 = 58

Hypotenuse = √58 = 7.616

The perimeter of the kite is the sum of the length of each side. Therefore,

Perimeter = 5 + 5 + 7.616 + 7.616 = 25.2 units to the nearest tenth

| 7 + m | - 4 &gt; 8
cestrela7 [59]

Answer:

m > 5 or m < -19

Step-by-step explanation:

We are given the Inequality:

\displaystyle \large{ |7 + m|  - 4 > 8}

First, add both sides by 4.

\displaystyle \large{ |7 + m|  - 4 + 4 > 8 + 4} \\  \displaystyle \large{ |7 + m|  > 12}

<u>A</u><u>b</u><u>s</u><u>o</u><u>l</u><u>u</u><u>t</u><u>e</u><u> </u><u>V</u><u>a</u><u>l</u><u>u</u><u>e</u><u> </u><u>P</u><u>r</u><u>o</u><u>p</u><u>e</u><u>r</u><u>t</u><u>y</u>

\displaystyle \large{ |a|  =  \sqrt{ {a}^{2} } }

Given a = any expressions and b = any positive numbers, zero or any expressions.

\displaystyle \large{ |a|  =  b \longrightarrow a =  \pm b}

From the Inequality, change > to equal

\displaystyle \large{ 7 + m   =   \pm12}

Subtract 7 both sides.

\displaystyle \large{  7 - 7 + m   =  \pm12 - 7} \\ \displaystyle \large{  m   =   \pm12 - 7}

±12-7 can be 12-7 = 5 or -12-7 = -19

\displaystyle \large{  m   =   5, - 19}

Refer to the attachment. The region is when the absolute value function is greater than constant function y = 12 or a blue horizontal line.

Since the absolute graph is above constant graph when x > 5 and x <-19.

Therefore,

\displaystyle \large{  m    >  5, m < - 19}

The length of the hypotenuse of a 30° -60° -90° triangle is 4. Find the longer leg.
Oduvanchick [21]

longest leg = 2\sqrt{3}

The longest leg is opposite the 60° angle

= 4 × sin60°

= 4 × \sqrt{3} / 2 = 2\sqrt{3}
