Answer:

The mural painting will be of 15.5 inches.

Step-by-step explanation:

We solve this question by proportions, using rules of three.

Scale of 4 inches = 1 inch

This means that 4 inches of real dimensions is one inch on the drawing.

How large will the mural painting of a rose bloom be if the actual height of the rose bloom is 61 inches?

The painting is a fourth of the real bloom(61 inches). So

61/4 = 15.5 inches

The mural painting will be of 15.5 inches.

A surveyor standing on top of a cliff found that the angle of depression of a boat as sea is 22°. if the top of the cliff is 15m

Alex73 [517]

Answer:

From the photo above i interpreted the question and drew a triangle to make it easier to solve

Tan is used to solve the question as we were given opposite (as height of the cliff) and to find Adjacent ( the distance between the foot of the cliff to the boat)

Tan θ =Opp/Adj

Tan 22°=15/a

Cross Multiply

aTanθ=15°

Divide both sides by Tan 22

aTan22/Tan22 = 15/Tan 22

a = 15/Tan 22°

a = 37.13 m

Therefore the distance between the foot of the cliff to the boat is 37.13 metres

A box contains 12 balls of which 5 are red, and 7 are blue. If 4 balls are drawn from the box, in how many ways can this be done

mash [69]

Answer:

175 ways

Step-by-step explanation:

5 balls are red, and 7 balls are blue making a total of 12 balls.

4 balls are drawn from the box,

1 ball is red and 3 balls are blue out of the 4 drawn from the box.

We have to choose 1 ball from 5 red balls and 3 blue balls from 7 blue balls.

Since the order is not essential we use combinations to find out

5C1 * 7C3= 5*35 = 175 ways
