Answer:

Tanto Pedro como Jorge deberán pintar 1/4 de la habitación cada uno.

Step-by-step explanation:

Dado que el cuarto entero es igual a 1, y que Arturo por ser el mayor de los hermanos tiene que pintar 1/2 de él, la parte que falta pintar es igual a 1/2 restante.

De ese 1/2, los hermanos menores, Pedro y Jorge, deben pintar dicha fracción en partes iguales. Por lo tanto, dado que (1/2) / 2 es igual a 1/4, la fracción que tanto Pedro como Jorge deberán pintar es de 1/4 de la habitación.

Simplify 12cm to 2.5mm
julia-pushkina [17]

Given:

12cm to 2.5mm

To find:

The simplified for of given statement.

Solution:

We know that,

1 cm = 10 mm

12 cm =120mm

We have,

12cm to 2.5mm

It can be written as

\dfrac{12\ cm}{2.5\ mm}=\dfrac{120\ mm}{2.5 mm}

\dfrac{12\ cm}{2.5\ mm}=\dfrac{120}{2.5}

\dfrac{12\ cm}{2.5\ mm}=48

Therefore, the value of 12 cm to 2.5 mm is 48 or 48:1.

5) In the figure, triangle ABC is a right triangle at B. If CD = 15, find BC to the nearest tenth.
ycow [4]

Answer:

BC ≈ 4.0

Step-by-step explanation:

∠ DCA = 180° - 70° = 110° ( adjacent angles )

∠ DAC = 180° - (30 + 110)° ← sum of angles in triangle

∠ DAC = 180° - 140° = 40°

Using the Sine rule in Δ ACD to find common side AC

\frac{AC}{sin30} = \frac{15}{sin40} ( cross- multiply )

AC × sin40° = 15 × sin30° ( divide both sides by sin40° )

AC = \frac{15sin30}{sin40} ≈ 11.668

Using the cosine ratio in right triangle ABC

cos70° = \frac{adjacent}{hypotenuse} = \frac{BC}{AC} = \frac{BC}{11.668} ( multiply both sides by 11.668 )

11.668 × cos70° = BC , then

BC ≈ 4.0 ( to the nearest tenth )

PLEASE HELP PLA
aleksley [76]

Answer:

y = -x+8

Step-by-step explanation:

The side that is parallel to BC is EF

Find the slope of EF:

m = \frac{2-4}{6-4} =\frac{-2}{-2} =-1

Easiest way is just put the formula in point-slope form and simplify.

Let's use point F, which is (6,2)

y -2=-(x-6)

Simplify:

y-2=-x+6

Add 2 on both sides:

y = -x+8

Hope this helped
