7 0

In order to get the answer to this question, we first have to subtract 350 and 70 in order to get the unit change of the two numbers. So after subtracting 350 and 70, we will get an answer of 280. After that, we simply divide 280 with 350 in order to get the percentage of change. After division, we will get an answer of 0.8. In order to get the percentage form of that value, we will just multiply 0.8 with 100 to get 80 or 80%

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

Ives us

$63.966$

Round if neededd.
