Answer:

N = 55

Step-by-step explanation:

c = 73

b = 48

$a^2 = c^2-b^2$

$a^2 = (73)^2-(48)^2$

$a^2 = 3025$

Square root $a^2$ to get N

N = $\sqrt{3025} = 55$

Answer:

$y = 2 \: and \: x = 2.5$

y=2x-3

2=2

$y = 2x - 3 \\ y = |2 \times 2.5| - 3 \\ y = 5 - 3 \\ y = 2 \\$

Jack and Jill start driving from the same location. Jack drives 30 miles south while Jill drives west. If Jack and Jill are 78 m

arsen [322]

Answer:

72 mles

Step-by-step explanation:

For better understanding, I'll make use of an attachment.

From the attachment,

O represents the start point

$OB = 30$ --- Jack

$AB = 78$ -- Distance between them

Required

Find OA; Jack's distance

To do this, we make use of Pythagoras theorem

$AB^2 = OA^2 + OB^2$

This gives:

$78^2 = OA^2 + 30^2$

$6084 = OA^2 + 900$

Subtract 900 from both sides

$OA^2= 6084 - 900$

$OA^2= 5184$

Take square roots

$OA = \sqrt{5184}$

$OA = 72$

<em>Hence, Jill drove 72 miles</em>

a culinary club earns $1360 from a dinner service. they sold 45 adult meals and 80 student meals. an adult meal costs twice as m

Georgia [21]

The adult meals cost 16$ and the student meals cost 8$. A=16 and S=8. 80•8= 640 you then take eight and multiply it by two and get 16 because it says the adult meals were twice as much. 45•16= 720.
640+720= 1360
