Answer:

[tex]15360\,\,rupees[/tex]

Step-by-step explanation:

Let sides of the triangle be [tex]a,b,c[/tex]

[tex]a=40\,,\,b=24\,,\,c=32[/tex]

Semi-perimeter (s) = [tex]\frac{a+b+c}{2}[/tex]

[tex]=\frac{40+24+32}{2}\\ =\frac{96}{2}\\=48[/tex]

Area of one tile [tex]=\sqrt{s(s-a)(s-b)(s-c)}[/tex]

[tex]=\sqrt{48(48-40)(48-24)(48-32)}\\ =\sqrt{48(8)(24)(16)}\\ =\sqrt{147456} \\=384\,\,cm^2[/tex]

So,

Area of 20 tiles [tex]=20(384)=7680\,\,cm^2[/tex]

Cost of polishing the floor at the rate of 2 rupees per sq.cm = [tex]7680(2)=15360\,\,rupees[/tex]

Answer:

8420

Step-by-step explanation:

10 to the third power will move the decimal point three place values to the right. So, the first two times you move it, you get 842, and so there is a 0 on the end to signify that it moved the third time.

Supplement angle: 170°

Step-by-step explanation:

Equations

Let x=the required angle. Since complementary angles sum 90°, then 90-x is the complement of x. According to the conditions of the question:

[tex]90-x=40+4x[/tex]

Simplifying:

[tex]90-40=4x+x=5x[/tex]

Solving:

[tex]x=50/5=10[/tex]

The angle is 10°. The supplement angle is 180°-10°=170°.

Supplement angle: 170°

D. Replace f(x) with y

Step-by-step explanation:

apex

Yoshi needs to find the inverse of f(x) = 5x – 2. The first step is to Switch x and y. The correct answer is option C.

In mathematics, an inverse function is a function that "undoes" the actions of another function. If a function f(x) maps an input x to an output y, the inverse function, denoted as f^(-1)(x) or sometimes written as f(x)^(-1), maps the output y back to the original input x. The correct answer is option C.

To find the inverse of a function, the first step is to switch the x and y variables. In this case, the function is f(x) = 5x - 2.

To find the inverse, we need to switch x and y, so the new function becomes x = 5y - 2.

It's important to note that not all functions have an inverse. A function must be one-to-one (each input maps to a unique output) for an inverse to exist. Additionally, the domain and range of a function and its inverse are swapped.

Answer:

We know that the area of a triangle is:

1/2 * base * height

We are given:

base = x + 6

height = x

area = 108 m^2

Applying the formula:

Area  = 1/2 * base * height

108 = 1/2 * x * (x + 6)

x² + 6x = 216

x² + 6x - 216 = 0

x² + 18x - 12x -216 = 0   (Splitting the middle term)

x(x + 18) - 12(x + 18) = 0

(x + 18) (x - 12) = 0

Hence, we have 2 possible values for x:   -18 or 12

Since taking x as -18 will result in the length of sides of this triangle to be negative, -18 is NOT the value of x

Therefore, x = 12

Answer:

32/81

Step-by-step explanation: multiply the numerator by 2 and the denominator by 3.

Answer:

  32/81

Step-by-step explanation:

Each term in the sequence is 2/3 of the previous one. Following that same pattern, the next term is 2/3 of the last one.

  16/27 × 2/3 = 32/81

By 2 = 2290

By 3 = about 1526.6667 or you can just write 4580/3

By 5 = 916

By 9 = about 508.8889

Answer:

Less than 3,

9/4

Step-by-step explanation:

It is given that Lu hit x numbers of home run.

So, number of home run hit by Karinne is  more home runs than 1/2 the number of home runs Lu hit.

So, number of home run Karinne hit is :

[tex]y = 4 + 0.5x[/tex]

Also,

[tex]x + y = 10[/tex]

Solving above two equation, we get :

x + ( 4 + 0.5x ) = 10

1.5x + 4 = 10

1.5x = 6

x = 4

Therefore, number of home run hit by Lu is 4.

Hence, this is the required solution.

Creating a mathematical expression using the scenario described, the expression which represents the total number of home runs is 1.5x + 4 = 10

Total Number of home runs :

(1/2)x + 4 + x = 10

1.5x + 4 = 10

1.5x = 10 - 4

1.5x = 6

x = 6/1.5

x = 4

Therefore, the equation which represents the situation is 1.5x + 4 = 10

Answer:

8

Step-by-step explanation:

if y varies with x, then they are directly proportional, so their ratio is constant (ie x divided by y is allways the same)

when x = 6, y = 24:

y / x = 4

when y = 32:

32 / x = 4

so x = 32 / 4 = 8

Answer:

54°

Step-by-step explanation:

Since m<2 + m<1 is equal to 180, we can set up the equation to find m<1.

plug in 126 as m<2, so we get

126 + m<1 = 180

-126              -126

m<1 = 54.

From this knowledge, we know that

Answer:

(1) The cost formula is: y = $19,050 + $12·x.

(2) The cost of moving materials if 340 moves are made is $23,130.

(3) 82.81% of the variability in moving cost is explained by the number of moves.

Step-by-step explanation:

The computer output for the regression analysis of 80 data points is as follows:

Intercept:  $19,050

Slope: 12

Coefficient of correlation: 0.91

Standard error:  $220

(1)

The general formula of regression equation is:

y = a + b·x

Here,

a = intercept

b = slope

The cost formula is:

y = $19,050 + $12·x

(2)

Predict the cost of moving materials if 340 moves are made as follows:

[tex]y = 19050 + 12\cdot x\\=19050+12\times 340\\=19050+4080\\=23130[/tex]

Thus, the cost of moving materials if 340 moves are made is $23,130.

(3)

The coefficient of determination R² specifies the percentage of the variance in the dependent variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent-variable).

The coefficient of determination R² can be computed by squaring the correlation coefficient value.

[tex]R^{2}=(r)^{2}=(0.91)^{2}=0.8281[/tex]

Thus, 82.81% of the variability in moving cost is explained by the number of moves.
