I Need a The Answer Plz!!! Geometry Is Hard

Mathematics
1 answer:
Veseljchak [2.6K]3 years ago

Answer:

36

Step-by-step explanation:

Triangle FED and Triangle AEC are similar.

That means, the ratio of corresponding sides are equal. Thus we can say:

\frac{ED}{DF}=\frac{EC}{CA}

Also, since EC is 39 and D is the midpoint, ED and DC are half of that. Hence ED = 39/2 = 19.5

Now we can use the ratio to solve for AC:

\frac{19.5}{18}=\frac{39}{CA}\\19.5CA=18*39\\19.5CA=702\\CA=\frac{702}{19.5}CA=36

Hence, AC = 36

a local hamburger shop sold a combined total of 770 burgers and cheeseburgers on Monday there were 70 more cheeseburger sold tha
aliina [53]
Let the number of hamburgers = h

Let the number of cheeseburgers = c

Now we translate the given information into equations.

"combined total of 770 [ham]burgers and cheeseburgers"
h + c = 770

<span>"there were 70 more cheeseburger sold than hamburgers"
</span><span>
</span><span>c = h + 70
</span><span>
</span><span>
</span><span>Our system of equations is
</span><span>
</span><span>
</span><span />h + c = 770
c = h + 70

The second equation is already solved for c, so we replace c of the first equation with h + 70.
h + h + 70 = 770
2h + 70 = 770
2h = 700
h = 350

Answer:  350 hamburgers were sold on Monday.

Jamar has a large rectangular box that is 6ft x 8ft x 7ft. Will this box fit a pipe that is 12 ft. Long? Determine the length of
Sav [38]

Answer:

9.21ft

Step-by-step explanation:

Given data

L= 6ft

W= 8ft

H= 7ft

Let us find the diagonal of the side, this represents the longest size of pipe the box can take

z^2= L^2+ H^2

z^2= 6^2+ 7^2

z^2= 36+49

z^2= 85

z= √85

z= 9.21ft

Hence the 12ft cannot fit into the box

the length of pip that can fit is 9.21ft
