Cost pc 7 meter cloth is 161 find the cost of 3 meter and 5 meter and 9 meter of the same cloth

Answer: 0.75

Step-by-step explanation:

Cos A = 0.8 = 4/5

Note that:

sin = opposite / hypotenuse

cos = adjacent / hypotenuse

tan = opposite / adjacent

Since cos = adjacent / hypotenuse

Therefore, we need to find the opposite which will be:

Hypothenuse² = Opposite² + Adjacent²

5² = Opposite² + 4²

Opposite² = 5² - 4²

Opposite² = 25 - 16

Opposite² = 9

Opposite = ✓9

Opposite = 3

Since tangent = opposite / adjacent

Tan a = 3/4 = 0.75

Given:

Grocery store located at point (5,-4).

Park is located at point (-5,4).

Paula's house is halfway between the Grocery store and park.

School is halfway between the Paula's house and park.

To find:

Ordered pair for the school.

Solution:

Formula used:

[tex]\text{Midpoint}=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Paula's house is halfway between the Grocery store and park. It means the location of Paula's house is the midpoint of (5,-4) and (-5,4).

[tex]\text{Paula's house}=\left(\dfrac{5+(-5)}{2},\dfrac{(-4)+4}{2}\right)[/tex]

[tex]\text{Paula's house}=\left(\dfrac{0}{2},\dfrac{0}{2}\right)[/tex]

[tex]\text{Paula's house}=\left(0,0\right)[/tex]

So, the Paula's house is located at (0,0).

School is halfway between the Paula's house and park. It means the location of the school is the midpoint of (0,0) and (-5,4).

[tex]\text{School}=\left(\dfrac{0+(-5)}{2},\dfrac{0+4}{2}\right)[/tex]

[tex]\text{School}=\left(\dfrac{-5}{2},\dfrac{4}{2}\right)[/tex]

[tex]\text{School}=\left(-2.5,2\right)[/tex]

Therefore, the correct option is B.

Please solve the third question and answer in the comments and I will tell you if you are correct.

Step-by-step explanation:

1)Find the solution of the following system of equations; express the answer as a coordinate pair (x,y):

y = x + 3         subtract from the bottom  and solve for x

y = -2x - 3    

y - y = x - (-2x) + 3 - (-3)

  0  =  3x + 6

 -6  =  3x

-2  =  x

 y = x + 3     y = -2 + 3     y = 1      (-2, 1)

2)Find the solution of the following system of equations; express the

answer as a coordinate pair (x,y):

y = 2x + 1              subtract from the bottom  and solve for x

y = x/2 + 4

y-y = 2x - 1/2 x +1 - 4

 0  = x(2-1/2) - 3

 3  = 1.5x

 2  = x          y = 2x + 1      y = 2(2) + 1       y = 5       (2, 5)

3) Find the solution of the following system of equations; express the

answer as a coordinate pair (x,y):

y = -3x + 6          subtract from the bottom  and solve for x

y= -1/2x+1            

y-y = x(-3 - (-1/2)) + (6 - 1)       follow the examples above

Answer:

Step-by-step explanation:

× A = 4y + 2 = 2(4y/2 + 2/2) = 2(2y + 1) ≠ 4(y + 2)

✓ B = 4y + 8 = 4(4y/4 + 8/4) = 4(y + 2) = 4(y + 2)

× C = y + y + y + y + 2 =

y (1 + 1 + 1 + 1) + 2 = 4y + 2 = A ≠ 4(y + 2)

✓ D = 5(y + 2) – (y + 2) = 5(y + 2) – 1(y + 2) =

(5 – 1)(y + 2) = 4(y + 2)

✓ E = y + y + y + y + 2 + 2 + 2 + 2 =

y (1 + 1 + 1 + 1) + (2 + 2 + 2 + 2) =

4y + 8 = B = 4(y + 2)

× F = 5(y + 2) – (y – 2) =

(5y + 10) + (-y + 2) =

(5y – y) + (10 + 2) =

4y + 12 = 4(y + 3) ≠ 4(y + 2)

The answer is 5 1/16

Step-by-step explanation:

3/2 x 3/2 x 3/2 x 3/2

3/2 x 3/2 = 9/4

9/4 x 3/2 = 27/8

27/6 x 3/2 =81/16

Turn 81/16 into a mixed fraction and it’s 5 1/16

Therefore, the answer is 5 1/16

Answer:

29.70

Step-by-step explanation:

Add up purchases 4.35+8.20+12.45+2.5=27.50

calc sales tax 27.50 x .08=$2.20

27.50+2.20=29.70

The solution is, 29.70 is the total amount Charlotte will pay for her purchases if there is an 8% sales tax.

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

here, we have,

given that.

from the given data, we get,

mouth wash = 4.35

detergent = 8.20

paper towels = 12.45

dish soap = 2.50

so, we get,

as total,

Add up purchases 4.35+8.20+12.45+2.5=27.50

now, we get,

calc sales tax 27.50 x .08=$2.20

so, we have,

27.50+2.20=29.70

Hence, The solution is, 29.70 is the total amount Charlotte will pay for her purchases if there is an 8% sales tax.

Answer:

The amount of the bill was $150.

Step-by-step explanation:

With the information provided, you can use a rule of three to find the amount of the bill which would represent 100% given that $27 represent 18%:

18%     →    27

100%   →      x

x=(100*27)/18

x=150

According to this, the answer is that the amount of the bill was $150.

Answer:

10.2

Step-by-step explanation:

20x=204

x=10.2

Answer:

x = 10.2

Step-by-step explanation:

To solve for x, we have to isolate it on one side of the = sign. The number on the other side is the value of x.

20x - 4 = 200

First, we can remove -4 from the equation. The inverse of -4 is +4, so we will add 4 to both sides. Adding 4 to -4 will neutralize it, making its value 0.

20x - 4 + 4 = 200 +4

Simplify this.

20x = 204

Now, we have 20 · x = 204. The inverse of multiplication is division. To the times 20, we will divide by 20 as well.

[tex]\frac{20x}{20}[/tex] = [tex]\frac{204}{20}[/tex]

Simplify.

x = 10.2

We can check this by substituting the value of x, 10.2, for the variable.

20(10.2) - 4 = 200

204 - 4 = 200

200 = 200

Since the equation is true, the answer must be 10.2.
