Answer:

<h2>3000 pcs</h2>

Step-by-step explanation:

given:

the Length, breadth and height of a wall is 5m,30cm and 3 m

find:

how many bricks of dimensions 20cm ×10 cm× 7.5 cm are required to build the wall​

solution:

vol of the wall = 5 x 3 x 0.30= 4.5 m³

vol per brick = 0.20 x 0.10 x 0.075 = 0.0015 m³

number of bricks =  <u> wall volume </u>

                                 vol. per brick

                             = 4.5 / 0.0015

                             = 3000 pcs of bricks required

What is the quotient of the synthetic division problem below, written in
ki77a [65]

The quotient of the synthetic division problem is "f(x) = -2x² + 9x + 5" (Option C).

<h3>What is Synthetic Division?</h3>

When a polynomial division is executed using the shorthand method, using a linear factor, one is  said to have executed a Synthetic Division.

The synthetic division translates to

- 2 15 -22 -15

<u>3 | -6 27 15</u>

-2 9 5 0

Citing the coefficient of the quotient of the first three numbers:

- 2, 9, 5. The last number is given as the remainder.

Hence the remainder is zero.

Given that the coefficient of the quotient are three, the interpretation is that the polynomial greatest degree is 2.

Thus,

f(x) = -2x² + 9x + 5

The radius of the semicircle in the following composite figure is 8.5 millimeters. What is the total area of the composite figur
nydimaria [60]

Answer:

13.35 millimeter. (About)

Step-by-step explanation:

To find the area or circumference of any circle, you need to use pi. So, if we are trying to fine the area of a <em>semicircle, </em>you use the the formula:

πr²/2

So, if the radius is 8.5,

8.5 · 3.14 = 26.69

Now we divide it by 2.

26.69 = 13.345

Since the question is asking to round to the hundredths, the answer will be 13.35 millimeters.
