Find the distance between (8, -4.7) and (8, 5.3)

irina [24]

Answer:

d = 10

Step-by-step explanation:

$d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\d= \sqrt{(8-8)^2+(5.3-(-4.7))^2} \\d= \sqrt{(0)^2+(10)^2} \\d= \sqrt{0+100} \\d= \sqrt{100}\\ d= 10$

Your math test scores are 76, 85, 92, and 63. What is the lowest score you can earn on the next test and still achieve an averag

sattari [20]

Hey there! I'm happy to help!

We have 5 test scores that give us an average of at least 75.

76, 85, 92, 63, x

We add these all up and divide by 5 to get 75.

Let's go backwards to find x.

We multiply by 5.

75(5)=375

We subtract all of the numbers except for x.

375-76-85-92-63=59

So, you need to earn at least 59 on the next test to achieve an average of at least 75.

Have a wonderful day! :D

In kite WXYZ, mZWY = 41° and mXYW = 11°<br><br><br> What is mWZY?

olchik [2.2K]

Answer:

128°

Step-by-step explanation:

In kite WXYZ, WY and XZ are longer and smaller diagonals respectively.

Longer diagonal bisects the opposite angles.

$\therefore m\angle ZYW =m\angle XYW$

$\because m\angle XYW = 11\degree... (given)$

$\therefore m\angle ZYW =11\degree$

$In\: \triangle WYZ$

$m\angle ZYW + m\angle ZWY + m\angle WZY=180\degree$

$11\degree + 41\degree+ m\angle WZY=180\degree$

$52\degree+ m\angle WZY=180\degree$

$m\angle WZY=180\degree - 52\degree$

$\purple{\bold {m\angle WZY=128\degree}}$
