The perpendicular room is 4m long, 3m wide and 2.5m high. They tiled and painted the interior walls of the room. Find the amount of paint to be used in wall painting (knowing that one coat of paint can paint 5m2).Answer only

Answers

Answer:

7 coats (cups) of paint

Step-by-step explanation:

The dimensions of the room are;

The length of the room, l = 4 m

The width of the room, w = 3 m

The height of the room h = 2.5 m

The area one coat (taking the coat to mean cup) of paint can paint, A/c = 5 m²/cup

The total surface area of the room wall, A = 2 × l × h + 2 × w × h

∴ A = 2 × 4 m × 2.5 m + 2 × 3 m × 2.5 m = 35 m²

The amount of paint to be used, c = A/(A/c)

∴ c = 35 m²/(5 m²/cup) = 7 cups

The amount of paint to be used, c = 7 cups

Q- y = 7 is a line which is-(A) Parallel to y-axis (B) Parallel to x-axis (C) Passing through (7, 7) (D) Passing through origin​

Answers

Answer:  (B) Parallel to x-axis

===================================================

Explanation:

Every point on the line y = 7 has a y coordinate of 7. Two such points are (0,7) and (1,7). The x coordinate can be anything you want. This line is completely horizontal and parallel to the x axis.

We can think of y = 7 as y = 0x+7. It's of the form y = mx+b with m = 0 as the slope and b = 7 as the y intercept.

How to construct a line segment?

To construct a line segment, the correct matching of the steps are given below as follows:

Step one: Start with line segment PQ that we will copy.

Step two: Set the compass point on the point P of the line segment to be copied.

Step three: Adjust the compass width to the point Q. The compass width is now equal to the length of the line segment PQ.

Step four:Mark a point R that will be one endpoint of the new line segment.

Step five : Without changing the compasses width, place the compasses point on the point R on the line you drew previously.

Step six: without changing the compasses width draw an arc roughly where the other endpoint will be.

Step seven pick a point S on the arc that will be the other endpoint of the new line segment.

Step eight: Draw a line from R to S.

Step nine: The line segment RS is equal in length (congruent to) the line segment PQ.

1. Find the value of x, rounded to the nearest tenth

A. 3.7
B. 4.4
C. 8.9
D. 4.2

Answers

Answer:

C 8.9

Step-by-step explanation:

all these lines (from the same point of origin, cutting into and through a circle, ending at the far end of the circle they are cutting into) have the same relation of their lengths :

a×(a+b) is the same for all these lines.

with a being the first segment from the point of origin to touching the outside of the circle, and b being the length of the line inside the circle.

so,

4×(4+16) = 8×(8+2) = 80

this is correct for these two lines.

now, the line with the length x is a special case, as it does not really go through a circle, it only touches them.

but the length relation applies also to this line. it is just that the length inside the circle is 0.

so,

x×(x+0) = 80 (the same value as for the other lines)

must be true here too.

=>

x² = 80

x = sqrt(80) ≈ 8.9

Convert 150 base 10 to a binary
number.

Answers

Answer:

10010110

Step-by-step explanation:

A binary number is basically a number in base 2. So, each place represents a power of two. The ones place represents 1 or 2^0, the tens represents 2 or 2^1, the hundreds represents 4 or 2^2 and so on. To find the highest place needed to make in the number in binary, we find the greatest power of two that is below 150. In this case, it is 128. We can start by writing 128 in binary:

10000000

Now, we subtract 128 from 150 and find the largest power of two that is smaller than the difference. The largest power of 2 smaller than 22 is 16, so we put a one in the place for 2^4:

10010000

We can subtract 16 from 22 to get what is leftover to continue the process. We get 6, and the largest power of 2 smaller is 4. We can place a one in the hundreds place to represent it:

10010100

What is left is 6-4 or 2, which is just 2^1, so we can place it in the tens place:

10010110

Answers

Answer:

32.7 degrees

Step-by-step explanation:

The total exterior angle of any polygon is 360 degrees

Each exterior angle can be calculated by dividing this total by the number of sides

So we have each measure as 360/n

where n is the number of sides

here, we have n = 11

So we have each exterior angle as:

Woman was not yet made. The story (absurd enough!) is that Jupiter made her, and sent her to Prometheus and his brother, to punish them for their presumption in stealing fire from heaven; and man, for accepting the gift. The first woman was named Pandora. She was made in heaven, every god contributing something to perfect her. Venus gave her beauty, Mercury persuasion, Apollo music, etc. Thus equipped, she was conveyed to earth, and presented to Epimetheus, who gladly accepted her, though cautioned by his brother to beware of Jupiter and his gifts. Epimetheus had in his house a jar, in which were kept certain noxious articles, for which, in fitting man for his new abode, he had had no occasion. Pandora was seized with an eager curiosity to know what this jar contained; and one day she slipped off the cover and looked in. Forthwith there escaped a multitude of plagues for hapless man,such as gout, rheumatism, and colic for his body, and envy, spite, and revenge for his mind,and scattered themselves far and wide. Pandora hastened to replace the lid! but, alas! the whole contents of the jar had escaped, one thing only excepted, which lay at the bottom, and that was hope. So we see at this day, whatever evils are abroad, hope never entirely leaves us; and while we have that, no amount of other ills can make us completely wretched.Source: Bulfinch, Thomas.
