Jake bakes and sell apple pies. he sells each pie for $5.75. the materials to make the pies cost $40. the boxes jake puts the pi

dezoksy [38]

Answer:

$18\ pies$

Step-by-step explanation:

Let

x-------> the number of pies

we know that

$5.75x-40-12.50=50$ -----> linear equation that represent the situation

solve for x

$5.75x-52.50=50$

$5.75x=50+52.50$

$5.75x=102.50$

$x=102.50/5.75=17.8$

Round to the nearest whole number

$17.8=18\ pies$

Find the missing side

dybincka [34]

Answer:

7) 8.94

8) 6.71

Step-by-step explanation:

for both questions, use pythagorean theorem

$a^{2} + b^{2} = c^{2}$

<u>Question 7:</u>

$4^{2} + 8^{2} = c^{2}$

16 + 64 = $c^{2}$

80 = $c^{2}$

$\sqrt{80} = \sqrt{c^{2}}$

c = 8.94

<u>Question 8:</u>

$6^{2} + 3^{2} = c^{2}$

36 + 9 = $c^{2}$

45 = $c^{2}$

$\sqrt{45} = \sqrt{c^{2} }$

c = 6.71
