Answer:

The value of x in centimeters is 22.5 cm

Step-by-step explanation:

The corresponding sides of the similar triangles are proportion which means have equal ratios

∵ Δ ABC is similar to Δ FGH

∵ AB and FG are corresponding sides

∵ BC and GH are corresponding sides

∵ AC and FH are corresponding sides

→ That means the ratios between them are equal

∴ \frac{AB}{FG}  =  \frac{BC}{GH}  =  \frac{AC}{FH}

∵ AB = 6 cm and FG = 15 cm

∵ BC = 5 cm and GH = 12.5 cm

∵ AC = 9 cm and FH = x

→ Substitute them in the rule above to find x

∴ \frac{6}{15}  =  \frac{5}{12.5}  =  \frac{9}{x}

→ By using cross multiplication with the 1st and 3rd ratios

∵ 6 × x = 15 × 9

∴ 6x = 135

→ Divide both sides by 6 to find x

∵ \frac{6x}{6} = \frac{135}{6}

∴ x = 22.5 cm

∴ The value of x in centimeters is 22.5 cm

A 65 ft. long swimming pool is to be constructed. The pool will be 4 ft. deep at one end and 11 ft. deep at the other. To the ne
pishuonlain [190]

Answer:

Measure of the acute angle = 84°

Step-by-step explanation:

In the figure attached,

ABDE is a swimming pool having length 'AB' = 65 feet

Depth of one end of the pool is BE = 4 feet

And depth of the other end AD = 11 feet

Acute angle between the bottom of the pool (DE) and wall of the deep end (AD) is ∠ADE.

Now from ΔCDE,

tanx = \frac{EC}{DC}

tanx = \frac{7}{65}

x = \text{tan}^{-1}(\frac{7}{65})

x = 6.15°

Now measure of acute angle the bottom of the pool makes with wall at he deep end,

m∠ADE = (90 - 6.15)°

             = 83.85°

             ≈ 84°

The diameter of a planet is about 25,660 mi. The diameter of the planet's moon is about 35% of the diameter of the planet. What
kotegsom [21]

Answer:

4%

Step-by-step explanation:

Volume of sphere

v = (4/3)πr^3

Volume moon/ volume planet

We don't actually need the numeric value of the radius

just the 35% ratio

Radius of moon = .35 radius of planet

Vm/ Vp = (4/3)π(.35r)^3 / (4/3)π(r)^3

Cancel like terms

Vm / Vp = .35^3

Vm / Vp = 0.042875

Expressed as a percentage

Vm / Vp = 4.2875%

Rounded

Vm / Vp = 4%
