A floor of a rectangular hall measures 25 m long and 15 m wide . The cost of tiling is $100 per sq.metre. How much money isneeded for tiling the entire floor?

Answer:

The first option is correct: Angle 2 through 5

Step-by-step explanation:

Both angles 2 and 5 are directly vertical or opposite to each other and are the only angles that are proportionate/equal sizes.

The other three options are incorrect because angles 4 and 3 are not the same equal value and are right next to each other making them not vertically across.

angles 1 and 5 are close to being vertical but are not the same size as angle 1 is much smaller than angle 5.

angles 6 and 1 are next to each other making them not vertically to each other and angle 6 is much larger than angle 1.

the correct answer is angles 2 and 5, the first option.

To solve the above equation we will follow the BODMAS rule.

It stands for :

Solving this question by bodmas rule :

[tex] \tt{ = 9 \times 2 + ({5}^{3} \times 5) + 60 \div 10}[/tex]

[tex] \tt{ = 9 \times 2 + (5 \times 5 \times 5\times 5) + 60 \div 10}[/tex]

[tex] \tt{ = 9 \times 2 + (25 \times 5\times 5) + 60 \div 10}[/tex]

[tex] \tt{ = 9 \times 2 + (125\times 5) + 60 \div 10}[/tex]

[tex] \tt{ = 9 \times 2 + (625) + 60 \div 10}[/tex]

[tex] \tt{ = 9 \times 2 + 625 + 60 \div 10}[/tex]

[tex] \tt{ = 9 \times 2 + 625 + 6}[/tex]

[tex] \tt{ = 18 + 625 + 6}[/tex]

[tex] \tt{ = 643+ 6}[/tex]

[tex] \tt{ = \red{649}}[/tex]

Answer:

100.32

Step-by-step explanation:

1.) 100% + 14% = 114

2.) 114 divided by 100 = 1.14 (the multiplier)

3.) 88 x 1.14 = 100.32

Step-by-step explanation:

the angle of elevation is the angle on the ground at the end of the shadow abs aiming towards the sun.

we know one angle : the 90° between the tree and its shadow (on the ground).

so, we can calculate with Pythagoras the length of the line of sight bergen the end of the shadow and the top of the tree, which is the Hypotenuse of this right-angled triangle.

Hypotenuse² = 32² + 35² = 1024 + 1225 = 2249

Hypotenuse = sqrt(2249) = 47.42362281... m

the height of the tree is the sine of the angle of elevation multiplied by the length of the Hypotenuse (as the radius of the virtual circle).

32 = sin(angle) × sqrt(2249)

sin(angle) = 32/sqrt(2249) = 0.6747692...

angle of elevation = 42.43622979...° ≈ 42°

Answer:

25 days

Step-by-step explanation:

If 6 men each work for 5 hours a day:  6 x 5 = 30 hours of work per day

If it takes them 50 days to build the house, then 30 x 50 = 1500 hours work in total to build the house.

If 10 men are working 6 hours a day each:  10 x 6 = 60 hours of work per day.

So 1500 ÷ 60 = 25 days

Therefore, it would take 10 men 25 days to build a house if they were each working 6 hours per day.

a) The perimeter function of the rectangle is [tex]p = 18\cdot x -2\cdot x^{3}[/tex].

b) The domain of the perimeter function is [tex]x \in [-3, 3][/tex].

a) The perimeter of a rectangle ([tex]p[/tex]) is the sum of the lengths of its four sides:

[tex]p = AB\cdot AC[/tex] (1)

If we know that [tex]AB = 2\cdot x[/tex] and [tex]AC = 9-x^{2}[/tex], then the perimeter of the rectangle is represented by the following formula:

[tex]p = 2\cdot x \cdot (9-x^{2})[/tex]

[tex]p = 18\cdot x -2\cdot x^{3}[/tex]

The perimeter function of the rectangle is [tex]p = 18\cdot x -2\cdot x^{3}[/tex]. [tex]\blacksquare[/tex]

b) The domain of the function is the set of values of [tex]x[/tex] associated to the function. After a quick inspection, we find that the domain of the perimeter function is [tex]x \in [-3, 3][/tex]. [tex]\blacksquare[/tex]

The given statement "Are positive and negative numbers the same" is false.

False. Positive and negative numbers are not the same. Positive numbers are greater than zero, while negative numbers are less than zero. They are opposites of each other.

For example, 10 is a positive number, while -10 is a negative number. 10 is greater than 0, while -10 is less than 0.

Answer:

If the perimeter of the rectangle is 60 feet, how long are the base and height of Herman's rectangle? Show how you know.

Step-by-step explanation:

B=4x|(4.10) x+x+4x+4*=60.

The dimension of the Herman rectangle will be 24 feet by 6 feet.

Let W be the rectangle's width and L its length.

The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be

Perimeter of the rectangle = 2(L + W) units

If the perimeter of the rectangle is 60 feet. And we know that the ratio of length to width of Herman rectangle will be 4/1.

L = 4W

Then the equation is given as,

60 = 2 (4W + W)

30 = 5W

W = 6 feet

Then the size of the length is given a,

L = 4W

L = 4 x 6

L = 24 feet

The dimension of the Herman rectangle will be 24 feet by 6 feet.

What's the common factor found except 1

Let's see how..

So the required simplification is

Answer:

slope = 1

y-intercept = (0 , -4)

x - intercept = (4 , 0)

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

Note that there is no number besides the x. When this happens, the slope is to be assumed as 1.

The number (and sign) that replaces the b is the y-intercept. In this case, it is (0 , -4).

The x-intercept is the point in which you intercept the y-line at 0. Plug in 0 for y, and solve for x:

0 = 1(x) - 4

0 = x - 4

0 (+4) = x - 4 (+4)

x = 4

x-intercept = (4 , 0)

Answer: x = 6

Step-by-step explanation:

Because we are given that the two figures are already similar, we can set up a proportional relationship to determine the value of x. Since the larger rectangle has a width of 21 and the smaller rectangle has a width of 7, those values can be used as the numerators in the proportion. Since the larger rectangle's length is x plus the additional 3 units on the smaller rectangle, x+3 and 3 can be used as the denominators in the proportion.

Next, we set up the proportion as follows:

[tex]\frac{21}{x+3} =\frac{7}{3}[/tex]

Then, you cross multiply to get the equation:

[tex]63=7x+21[/tex]

After solving down algebraically, you get the value of x to be 6.
