Answer: it's A

Step-by-step explanation:

since the cost for hiring a plumber for three hours costs $120 so in graph A the graph has more likely stopped at $120 on the y axis which can be said as the cost axis too. I'm pretty sure the answer is A!

What is the nearest perimeter of rectangle ABCD, to the nearest tenth?

Snowcat [4.5K]

Answer: B

Step-by-step explanation:

Perimeter = 2(length+width)

'CD' = 20×cos(30) = 17.3205

width 'AD' = 20×cos(60) = 10

Perimeter = 2(17.3205+10)

= 2(27.3205)

= 54.641 =54.6

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

Area for a kite<br> I don’t know how to find the area pls help

dusya [7]

Answer:

63.966

Step-by-step explanation:

Area of a kite is

$\frac{pq}{2}$

where p and q are the diagonals.

The horinzontial diagonal is 8.

We need to find the vertical diagonal length.

The top triangle diagonal measure is

${4}^{2} + {x}^{2} = {7}^{2}$

$16 + {x}^{2} = 49$

${x}^{2} = 33$

$x = \sqrt{33}$

The bottom triangle diagonal measure is

${4}^{2} + {x}^{2} = {11}^{2}$

$1 6 + {x}^{2} = 121$

${x}^{2} = 105$

$x = \sqrt{105}$

Add the two diagonals.

$\sqrt{105} + \sqrt{33}$

Substitute this in for the formula

$\frac{8 \times ( \sqrt{105} + \sqrt{33} }{2}$

Which simplified gu
