Answer:

a b and c

Step-by-step explanation:

a) a number is divisible by 3 if the sum of its dígits is divisible by 3:

3+4+5+1+5=18

<em>18 is divisible by 3 (6*3=18), then 34515 is divisible by 3 too.</em>

b)a number is divisible by 9 if the sum of its dígits is divisible by 9:

3+4+5+1+5=18

<em>18 is divisible by 9 (9*2=18), then 34515 is divisible by 9 too.</em>

c) a number is divisible by 5 if its last digit is 5 or 0

then, <em>34515 is divisible by 5</em>

Answer/Step-by-step explanation:

Using α as reference angle:

Perpendicular side = BC (one of the legs that adjoins to form a right angle. It is opposite to the reference angle.)

Base side = AB (The other leg that forms a right angle with the perpendicular side at the adjoining point. It is adjacent to the reference angle)

Hypotenuse = AC (the side opposite to the right angle, 90°)

Using β as reference angle:

Perpendicular side = AB (one of the legs that adjoins to form a right angle. It is opposite to the reference angle.)

Base side = BD (The other leg that forms a right angle with the perpendicular side at the adjoining point. It is adjacent to the reference angle)

Hypotenuse = AD (the side opposite to the right angle, 90°)

A bath tub drained at a constant rate. The table shows the number of gallons of water left in the tub after being drained for tw
Greeley [361]

The rate at which the water was drained from the tank is 6 gallons of water per minute (option A)

To know the speed at which the tank was drained, we must carry out the following operations:

Taking into account the information provided by the table we establish how much water has been drained from the tank in 20 minutes.

450 gallons - 330 gallons = 120 gallons.

Subsequently, we must divide the amount of water (120 gallons) that was drained by the time it was drained (20 minutes).

120 gallons ÷ 20 minutes = 6 gallons / minute.

According to the above, we can establish that the bath drain rate is 6 gallons / minute (option A).

Note: This question is incomplete because there is some missing information. Here is the complete information:

What is the rate at which the water was drained from the tank?

  • 6 gallons of water per minute.
  • 11 gallons of water per minute.
  • 45 gallons of water per minute.
  • 120 gallons of water per minute.

Parallelogram RSTU is rotated 180° clockwise
julia-pushkina [17]

Answer:

Two pairs of parallel sides

Step-by-step explanation:

The given transformation performed on parallelogram RSTU = 180° clockwise rotation

Given that a rotation is a form of rigid transformation, the shape and size of the preimage RSTU will be equal to the the shape and size of the image R'S'T'U'

Therefore, RSTU ≅ R'S'T'U' and R'S'T'U' is also a parallelogram with two pairs of parallel sides.
