Answer:

Area = 3.0 square cm

Step-by-step explanation:

By cosine formula,

WX² = WY² + XY² - 2(WY)(XY)cos(∠W)

WX² = (1.5)² + (4.8)² - 2(1.5)(4.8)cos(52°)

WX² = 2.25 + 23.04 - 8.866

WX = √(16.424)

WX = 4.05 cm

Since, area of a triangle with known sides = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Here, s = [tex]\frac{a+b+c}{2}[/tex]

And a, b, c are the sides of the triangle

By this formula,

s = [tex]\frac{1.5+4.8+4.05}{2}[/tex]

s = 5.2

Therefore, area of the triangle XYZ = [tex]\sqrt{5.2(5.2-1.5)(5.2-4.8)(5.2-4.05)}[/tex]

= [tex]\sqrt{5.2(3.7)(0.4)(1.15)}[/tex]

= [tex]\sqrt{8.85}[/tex]

= 2.97

≈ 3.0 square cm

Answer:

By solving x and y

Step-by-step explanation:

Answer:

x ≈ 39.2 , y ≈ 34.3

Step-by-step explanation:

Using the sine and tangent ratios in the right triangle

sin29° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{19}{x}[/tex] ( multiply both sides by x )

x × sin29° = 19 ( divide both sides by sin29° )

x = [tex]\frac{19}{sin29}[/tex] ≈ 39.2 ( to 1 dec. place )

------------------------------------------------------

tan29° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{19}{y}[/tex] ( multiply both sides by y )

y × tan29° = 19 ( divide both sides by tan29° )

y = [tex]\frac{19}{tan29}[/tex] ≈ 34.3 ( to 1 dec. place )

Step-by-step explanation:

volume of cylinder= πr²h

r= 12cm

h = 19cm

putting the values in the formula

Answer:

The given line has slope m=1

the perpendicular line MUST have slope -1

Since it MUST eat (-3,2), the intercept formula says

B = y - mx = 2 - (-1)(-3)  = 2 - 3 = -1

so the equation of the perpendicular line that eats point W is

y = -x -1

The lines y=x+3 and it's perpendicular y = -x-1 intersect at

  y = x+3 = -x-1

   2x+3 = -1

  2x = -4

  x = -2

THe intersection point is

(-2,1)

Finally by distance formula,

The distance between (-3,2) and (-2,1) is

 sqrt ( (-3 - -2)^2 + ( 2-1)^2)

= sqrt( (-3 + 2)^2 + (2-1)^2)

 = sqrt( (-1)^2 + 1^2)

  = sqrt ( 1+1)

 = sqrt(2)

Step-by-step explanation:

The distance between line l and the point E (-7, 0) will be;

D = 3.

What is distance between point and line?

The distance between a line ax + by + c = 0 and point (p, q) will be;

D = |ap + bq + c|/√a² + b²

Given that;

Equation of line;

y = -3

And, Point = E (- 7, 0)

Hence, The distance between a line and point is calculated as;

Equation of line;

y = -3

y + 3 = 0

Compare with ax + by + c = 0, we get;

a = 0, b = 1 and c = 3

And, Point = (p, q) = (-7, 0)

Thus, The distance between a line and point is;

D = |0 + 0 + 3|/√0+1

D = 3

So, The distance between line l and the point E (-7, 0) will be;

D = 3.

Answer:

20 months

Step-by-step explanation:

A leaky valve on the water meter overcharges Ahmed for one Liter of water for every [tex]2[/tex] months. The overcharged amount [tex]w[/tex] varies directly with time [tex]t[/tex].

(a)

As the overcharged amount [tex]w[/tex] varies directly with time [tex]t[/tex],

[tex]w=kt[/tex]

Here, [tex]k[/tex] is a constant.

A leaky valve on the water meter overcharges Ahmed for one Liter of water for every [tex]2[/tex] months.

Put [tex]w=1\,,\,t=2[/tex]

[tex]1=2k\\k=\frac{1}{2}[/tex]

So,

[tex]w=\frac{t}{2}[/tex]

(b)

To find the number of months it will take for Ahmed to be overcharged for 10 liters of water leaked, put [tex]w=10[/tex] in [tex]w=\frac{t}{2}[/tex]

[tex]10=\frac{t}{2}\\\\t=10(2)\\[/tex]

Answer:

  C. Bank A - she will make $230.02 more.

Step-by-step explanation:

The account balance at each bank can be computed from ...

  A = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years.

Bank A

Sumaya's balance after 5 years will be ...

  A = 8500(1 + 0.0225/2)^(2·5) = 9506.14

Bank B

Sumaya's balance after 5 years will be ...

  A = 8500(1 +0.0175/12)^(12·5) = 9276.67

__

The balance at Bank A is larger by ...

  9506.14 -9276.67 = 229.47

The closest answer choice is ...

Comment on the discrepancy

The difference between the offered answer choices and the values computed here arise from the use of rounding in intermediate calculations. We did no rounding until the final answer. The offered choices seem to be rounded to about 8 digits, possibly the consequence of using an inadequate calculator.

Answer: $6

Step-by-step explanation:

Cost of item = $4.38

Mark up percent = 35%

Sakes price will be the addition of the cost price and the mark up price. This will be;

= $4.38 + (35% × $4.38)

= $4.38 + (0.35 × $4.38)

= $4.38 + $1.533

= $5.913

= $6 approximately

Answer:

x=0

Step-by-step explanation:

ima break it apart so it is easier to understand, going from left to right.

15(x-3)/5 you will distribute the 15 to the x and the -3

15x-45/5 you will divide 5 to both the 15x and the 45

3x-9 it will now be combined with the right side

now on the right side:

3(2x-3) you will distribute the 3 to the 2x and -3

6x-9 will now be combined with the left side

combining the left and right.

3x-9=6x-9 combine both 'x' es and constants

3x-6x=9-9 solve

-3x=0 divide

-3x=0 /-3 (all of it will be divided by 3 cuz what you do to one side, you gotta do to the other)

x=0

without distributive property

15(x-3)/5=3(2x-3) remove the parenthesis from the left side

3(x-3)=3(2x-3) distribute the 3 through the parenthesis on both sides

3x-9=6x-9 the rest is the same as in the combined section up above.

i hope this helps

The value of the equation 15 ( x - 3 ) / 5 = 3 ( 2x - 3 ) is x = 0

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be A

Now , the value of A is given by

15 ( x - 3 ) / 5 = 3 ( 2x - 3 )

By using the distributive property , we get

On opening the bracket , we get

( 15x - 45 ) / 5 = 6x - 9

Divide by 5 on LHS , we get

3x - 9 = 6x - 9

Subtracting 6x on both sides of the equation , we get

-3x - 9 = - 9

Adding 9 on both sides , we get

-3x = 0

x = 0

Now , without using distributive property , we get

The equation is

15 ( x - 3 ) / 5 = 3 ( 2x - 3 )

Divide by 5 on both sides , we get

3 ( x - 3 ) = 3 ( 2x - 3 )

Divide by 3 on both sides , we get

x - 3 = 2x - 3

Adding 3 on both sides of the equation , we get

x = 2x

Subtracting x on both sides , we get

x = 0

Hence , The value of the equation 15 ( x - 3 ) / 5 = 3 ( 2x - 3 ) is x = 0
