Answer: four friends went out for dinner. the bill , including tax , totaled $64.00 if they want to leave a 15% tip and want to share the bill and tip equally

Step-by-step explanation:

The water gauge pressure at the house will be 9.63×10⁵ N/m².

Firstly we will be calculating the total height which will comprise of height from tank to house and elevated height. The formula for total height will be -

Total height = 5 + 110 sin 58°

Keep the value of sin 58° in formula and performing multiplication followed by addition

Total height = 5 + 110×0.848

Total height = 5 + 93.28

Total height = 98.28 meters

Now, calculating the water gauge pressure at house. The formula to be used is -

P = ρ×g×h, where P is pressure, ρ is density of water, g refers to acceleration due to gravity and h represents total height. We are aware that density of water is 1000 kg/m³ and accelerate due to gravity is 9.8 m/s².

Keep the values in formula to find the gauge pressure.

P = 1000 × 9.8 × 98.28

Performing multiplication

P = 963,144 N/m² or 9.63×10⁵ N/m²

Hence, the water gauge pressure at the house will be 9.63×10⁵ N/m².

The complete question is -

Answer: 45 yrs old

Step-by-step explanation:

Car A  = 9 yrs old

Car B = X yrs old

The ratio for the cars are

Car A : Car B

or

2 : 5

You want to make it easier to read so you make both the ratio number and the given age number (9) the same number.

Multiply Car A age by 2 to make it 18 and the Ratio 2 by 9 to make it 18. This makes them the same number. Since you did this to one side, you have to do it on the other side by multiplying the 5 by 9 which is 45.

Your new ratio is now

18 : 45

This means Car B is 45 yrs old

in fig. 3.1 the value of  x  is 20° , in fig. 3.2 the value of  x  is 40° ,  in fig.  the value of  3.3 x  is 10° ,  in fig. 3.4 the value of  x  is 120°.

In planar geometry, an angle is a shape made up of two rays or lines that share an endpoint. The English word "angle" derives from the Latin word "angulus," which means "corner." The vertex and the two rays are referred to as the sides of an angle, respectively, and are the shared termini of two rays.

3.1

straight lines makes an angle of 180° thus ,

              x + 2x + 120 = 180

                3x = 60

                  x = 20°

3.2

    sum of the angles of triangle is = 180°

     105 + 35 + x = 180

      140 + x = 180

       x = 40°

3.3

       since it is an isoceles triangle so the opposite angles to equal sides are equal

140 + 4x = 180

4x = 40

x = 10°

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Focus = (8,-6¹/2), directrix is y= -5¹/2

Answer:

x=44

Step-by-step explanation:

x32=10+x/2

Multiply the 2 from x over 2 to reverse the division equation.

2*x32=10+x/2*2

That results in 2 multiplying 32x and 2 multiplying the 2 in x over 2.

Because multiplication is the reverse of division, the 2's will cancel out and reduce x over to 2 to simply x.

2*32 is 64, include the x before the 64 just like the given equation exemplifies with the x before the 32.

The equation looks like the following once put together: x64=10+x

Subtract the x from the 10+x side of the equation underneath the x64.

x64=10+x

-x          -x

Which equals x63=10.

To receive the answer to this question, you have to divide the 63 on both sides.

63 divided by 63x leaves you with just the x.

63 divided by 10 leaves you with 6.3 in decimal form.

Thus, x equals 6.3.

To check if it's right, insert 6.3 for both x's.

(6.3)*32=10+(6.3)/2

Solve.

201.6=10+3.15

201.6=13.15

Clearly, this doesn't work.

So, I'm assuming you actually meant: 32=10+x/2.

Hence, you would multiply 2 on both sides.

2*32=10+x/2*2

We've established that 32*2 is 64 and the 2's would cancel out.

64=10+x

Subtract the 10 on both sides.

54=x

To see if this one is correct, plug in 54 to the x.

32=10+(54)/2

Divide 54 by 2 which equals 27.

32=10+27

32=37

Nope, that doesn't work either.

Thus, instead of multiplying by 2, we would first need to subtract the 10.

32=10+x/2

-10 -10

32-10 is 22 and it would leave the other side with just x over 2.

22=x/2

Now, we would have to multiply the 2 on both sides.

22*2=44 and x/2*2 gives us x.

So, 44=x.

Let's check.

32=10+(44)/2

32=10+22

32=32

Finally, we have our match.

In conclusion, x=44.

The equation x + 7 = 2 will have the value of x as 5.

We are given the equation:

x + 2 = 7

We need to solve the equation to find the value of x.

We will first subtract 2 from both the sides:

x + 2 - 2 = 7 - 2

So, subtracting 2 from both the sides, we get that:

x = 5

The value of the functions are:

(a) ( f - g )( 1 ) = - 1

(b) ( f · g )( 4 ) = 0

Before performing operations on functions, we must first comprehend the various function rules and how to get the function value at a given x-value. By applying this concept, we can determine the function value.

From the graphs, we have the functions,

f(x) = 2( | x - 2 | )

g(x) = - x + 4

Now,

(a) ( f - g )( 1 )

( f - g )( 1 ) = f( 1 ) - g( 1 )

( f - g )( 1 ) = 2 ( | 1 - 2 | ) - ( - 1 + 4 )

( f - g )( 1 ) = 2 ( | - 1 | ) - ( 3)

( f - g )( 1 ) = 2 - 3

( f - g )( 1 ) = - 1

(b) ( f · g )( 4 )

( f · g )( 4 ) = f( 4 ) · g( 4 )

The number of 8-inch long pieces of ribbon that the other class cut is 9.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

Given that Students in 3 art classes cut 728 inches of ribbon into 8-inch long pieces. Therefore, the number of ribbon that 3 classes together cut is,

Number of ribbon cut by 3 classes together = 728 inches / 8 inches = 91

Further, it is given that two of the classes together cut 656 inches of ribbon. Therefore, the number of ribbon that 2 classes together cut is 656.

Number of ribbon cut by 2 classes together = 656 inches / 8 inches = 82

Now, the number of  8-inch long pieces of ribbon that the other class cut can be written as,

Number of pieces cut by other class

Rounded to the nearest inch: 10

Rounded to the nearest tenth: 10.2

Rounded to the nearest hundredth: 10.25

Step-by-step explanation:

To find the area of a square, we multiply the side length by itself, or in other words, SQUARE the side length!

[tex]A=s^2[/tex]

We are given the area, so plugging that into our equation looks like this:

[tex]105=s^2[/tex]

To eliminate the exponent, take the square root of both sides of the equation!

[tex]\sqrt{105}=s[/tex]

From here, there are a few paths to take, depending on what your teacher is looking for. I will evaluate the approximate of the square root by finding the nearest perfect squares.

The nearest perfect square less than √105 is √100, and the nearest perfect square greater than √105 is √121.

105 is closer to 100 than to 121, so √105 is closer to √100.

√100 is equal to 10, so the √105 is approximately 10 inches!
