By definition, BF = 1/2 * CE;


So, BF = 1/2 * 90 = 45.

BF = 45

Answer:

BF=45

Step-by-step explanation:

Here the given point B and point F are the midpoint of the sides AC and AE respectively in triangle ACE .

According to converse of Thales theorem -if a line divides any two sides of a triangle in equal parts then that line will be parallel to the third side of the triangle.

Also ,

In the above said condition, that line will be half of the third side

On applying this concept in the given triangle ACE

BF= \frac{1}{2} *CE\\BF=\frac{1}{2} *90\\BF=45

Hence BF=45

Find the lateral area and total surface area of each of the following. GEOMETRY!!! HELP PLS
AlexFokin [52]

(a) The lateral surface area of the prism is 720 sq units and the total surface area is 752 sq units.

(b) The lateral surface area of the cone is 136π sq units and the total surface area is 200π sq units.

(c) The lateral surface area of the cylinder is 242π sq units and the total surface area is 484π sq units.

<h3>Lateral surface area of the prism</h3>

L.S.A = Ph

where;

  • P is perimeter of the base
  • h is height of the prism

h² = 17² - 8²

h² = 225

h = 15

L.S.A = (3 x 16) x 15 = 720 sq units

<h3>Total surface area of the prism</h3>

T.S.A = PH + 2B

T.S.A = 720 + 2(16) = 752 sq units

<h3>Lateral surface area of the cone</h3>

L.S.A = πrt

where;

  • t is the slant height = 17

r² = 17² - 15²

r² = 64

r = 8

L.S.A = π(8)(17) = 136π sq units

<h3>Total surface area of the cone</h3>

T.S.A = πrt + πr²

T.S.A = 136π sq units + π(8)²

T.S.A = 200π sq units

<h3> Lateral surface area of the cylinder</h3>

L.S.A = 2πrh

where;

  • r is the radius of the cylinder = 11
  • h is height of the cylinder = 11

L.S.A = 2π(11 x 11) = 242π sq units

<h3>Total surface area of the cylinder</h3>

T.S.A = 2πrh + 2πr² = 2πr(r + h)

T.S.A = 2π(11)(11 + 11)

T.S.A = 484π sq units.

Thus, the lateral surface area of the prism is 720 sq units and the total surface area is 752 sq units.

  • the lateral surface area of the cone is 136π sq units and the total surface area is 200π sq units.
  • the lateral surface area of the cylinder is 242π sq units and the total surface area is 484π sq units.

Rico spent $87.00 to go to the movies on Friday night. He spent $25.75 on popcorn and drinks and paid $12.25 for each movie tick
Svetlanka [38]
You haven't given the equations I'm supposed to chose from, but the answer would be 

25.72 + 12.25x = 87.00 is the equation.

He spent a total of $87

The popcorn was 25.75 and each ticket was 12.25, which means we must add the amounts they costs and multiply how my tickets he bought, which is x.

5 is the solution

One faucet fills up a bathtub in 15 minutes while the second fills it up in 10 minutes. If both faucets are turned on, what frac
yaroslaw [1]
Faucet one fills up \frac{1}{15} of the bathtub in one minute and faucet two fills up \frac{1}{10} of the bathtub in one minute. If both are one then they will fill up  \frac{1}{15}+ \frac{1}{10} =  \frac{5}{30} =  \frac{1}{6} So, 1/6 of the bathtub in one minute.
