How far up the house would a ladder be resting if it is 25 ft long and 3 ft
away from the house? Round to the nearest tenth if necessary.
5.3 ft
21 ft
24.8 ft
25.2 ft

Answers

Answer:

C

Step-by-step explanation:

The last one is absurd. You can't have a ladder reaching higher than itself. The question is a Pythagorean problem.

Givens

a = 3

b = ?

c = 25 feet

Formula

a^2 + b^2 = c^2

Solution

3^2 + b^2 = 25^2

9 + b^2 = 625                  Subtract 9 from both sides.

b^2 = 625 - 9

b^2 = 616                        Take the square root of both sides.

b = sqrt(616)

b = 24.8

Carla e Ana foram tomar sorvete e gastaram r$ 23,00 dividido a conta em partes iguais, quanto cada uma pagou ? Gente me explica como faz a conta não só resposta por favor

Answers

Answer:

each of them has to pay $11.5 individually

Step-by-step explanation:

The computation of the amount paid by each one is shown below:

As carla and Ana gone for an icecream and the bill is $23 that should be divided equally

So here the carla should pay

= $23 ÷ 2

= 11.5

And, Ana should pay

= $23 ÷ 2

= $11.5

Hence, each of them has to pay $11.5 individually

Answer:

AY = 4.8YD = 2.4

Step-by-step explanation:

Corresponding sides of the triangles are ...

  ΔFUN  . . .   ΔDAY

  UF = 10 . . .  AD = 6

  FN = 4 . . .  DY

  NU = 8 . . .  YA

Corresponding sides are proportional, so we have ...

  DY/4 = AD/UF = 6/10

  DY = 4(0.6) = 2.4

and

  YA/8 = 6/10

  YA = 8(0.6) = 4.8

The side lengths are ...

  AY = 4.8, YD = 2.4
