Answer:

28 m

Step-by-step explanation:

The top angle in the triangle = 90° - 62° = 28°

Using the cosine ratio in the right triangle

cos28° = \frac{adjacent}{hypotenuse} = \frac{25}{x}

cross- multiply

x × cos28° = 25 ( divide both sides by cos28° )

x = \frac{25}{cos28} = 28.31425... ≈ 28 m

Thus the distance from the top to the crocodile is 28 m

Answer:

28.31 m to the nearest cm.

Step-by-step explanation:

Note the angle next to the crocodile measures  62 degrees ( alternate angles).

The required distance is the hypotenuse of the triangle and the  height 25m is the opposite side to the angle of  62 degrees..

Therefore we have sin 62 = 25 /x  where x is the distance required.

x = 25 / sin 62

= 28.31 m.

$300 invested at 12% compounded monthly after a period of 1.5 years
GalinKa [24]

Answer: $358.8 to the nearest tenth

Step-by-step explanation:

Compound interest is calculated by Where: A = P(1 + r)t

Where P= 300, r= 12% = 0.12, t= 1.5 years

Slot in the figures

300 (1 + 0.12) 1.5

300 (1.12) 1.5

300x 1.12

336e1.12

A = $ 358.84

FinnZ [79.3K]

Answer:

Hence, a carpenter can paint a maximum of 7 chairs.

Hence, option A is correct.

Step-by-step explanation:

A carpenter has less than 120 min. to spend painting furniture each day.

Today, he has spent 30.5 min. painting a desk.

Now he will paint x chairs, each of which takes 12.5 min.

i.e. he will take a total of 12.5x minutes in painting 'x' chairs.

Also total time spent on painting furniture each day will be equal to time spent on painting a desk and all of the chairs.

Hence,

30.5+12.5x<120 (since the total time he spends on painting is less than 120 mins.)

⇒ 12.5 x<120-30.5

⇒ 12.5 x<89.5

⇒ x<7.16  ( on dividing both side of the inequality with 12.5)

Hence, a carpenter can paint a maximum of 7 chairs.
