Subtracting Rational Expressions

Answer:

[tex]4.5[/tex]

Step-by-step explanation:

In this answer, I'll be using a method called percent proportion.

[tex]\frac{percent}{100} = \frac{part}{whole}[/tex]      in this case part = is and whole = of

Answer:

0.045 is 1% of what number?

[tex]\frac{1}{100} = \frac{0.045}{x}[/tex] [tex]=[/tex] [tex]\frac{1x}{1} = \frac{4.5}{1} x=4.5[/tex]

Steps:

1. make your proportion.

2. cross-multiply your proportion. Remember we don't know what x equals.

3. divide both sides by 1.

4. Answer = [tex]4.5[/tex]

Have a nice day :)

Answer: Pretty sure it's 390$

Step-by-step explanation:

Answer:

$195 in total

Step-by-step explanation:

You would find the perimeter of the total garden first which equals 54 then times it by 1.5 and get 81 dollars for the gate. Then find the area of the triangle and get 120 then do 2 times 16 and get 32 then you add them together and get 152. Now with the 152 you divide it by 8 then multiple by 6 and finally add your 81 with 114 and get 195 dollars in total.

Answer:

$48.30

Step-by-step explanation:

Total profit after selling 5 cases:

[tex]5 \times 19.50 = 97.50[/tex]

Net loss:

[tex]145.80 - 97.50 = 48.30[/tex]

Answer:

She profited $9.78 for each of the 5 cases but she loss $48.3 in total.

Step-by-step explanation:

The principal amount for each case is 9.72. (So 19.5 - 9.72 = 9.78. )

For the loss, the money she used to buy - the amount she sold = loss.

( 145.8 - 97.5 = $48.3)

Answer:

[tex]27[/tex]

Step-by-step explanation:

We start by setting an equation.  We have [tex]2x+x+9=90[/tex] which simplifies to [tex]3x+9=90[/tex].  Subtract [tex]9[/tex] from both sides leaves us to solve for x when [tex]3x=81[/tex] divide by [tex]3[/tex] on both sides, we get [tex]x=27[/tex].

Answer:

r=1.024349

Step-by-step explanation:

The volume of a sphere is found with the formula: (4/3)×3.14×r³. So, if we use an algebra calculator (my favorite is mathpapa), the formula would be (4/3)×3.14×r³=4.5

The radius of a sphere with a volume of 4.5 [tex]\pi[/tex] cubic centimeters is

1.5 centimeters.

A sphere is a 3-dimensional solid figure with a radius and no sides and no vertex.

The formula for the volume of a sphere is

[tex]V = \dfrac{4}{3} \pi r^3[/tex],

Where V is the volume and r is the radius.

According to the data given in the question:

Substitute the given values in the formula,

[tex]4.5\pi = \dfrac{4}{3} \pi r^3[/tex]

Divide both sides of the equation by [tex]\pi[/tex]  gives:

[tex]4.5 = \dfrac{4}{3} \pi r^3[/tex]

Multiply both sides of the equation by [tex]\dfrac{3}{4}[/tex]  gives:

[tex]\dfrac{3}{4}(4.5) = r^3[/tex]

[tex]3.375 = r^3[/tex]

Taking the cube root of both sides gives:

[tex]r = \sqrt[3]{3.375}[/tex]

Using a calculator, we find that the cube root of 3.375  is 1.5 centimeters

Therefore, the radius of the sphere is 1.5 centimeters.

Hello!

Answer:

[tex]\Large \boxed{\sf 1.5L = 1500mL}[/tex]

Step-by-step explanation:

We want 1.5L in mL.

We have this table:

Let's put 1.5L:

kL      daL     hL     L        dL       cL     mL

                             1    .    5

Translate 1.5L into mL by moving the comma to the right until you reach mL:

kL      daL     hL     L        dL       cL     mL

                             1         5         0       0    

So 1.5L = 1500mL.

Step-by-step explanation:

Answer:

12

Step-by-step explanation: this is because if the circle is 24 then half the circle should be 12 if not then I don’t know your on you own

The area of a normal full circle is given by;

[tex]a = \pi \: r {}^{2} [/tex]

but since i want a semi circle, i would want that area to be split into 2, right?

So our new equation for the area of a semi circle is given by;

[tex]a = \frac{\pi \: r {}^{2} }{2} [/tex]

where r is the radius of our semi-circle.

The radius is half the diameter, so the radius here would be 24/2 =12

[tex]a = \frac{\pi \times 12 {}^{2} }{2} = \frac{144\pi}{2} = 72\pi = 72 \times 3.14159... = 226.194[/tex]

Answer:

235.62

Step-by-step explanation:

First you need to find the area of the big circle as a whole the equation is

A = pir^2

you need to plug in the radius of the big circle which would be

A = pi(10)^2

which equals

314.16

Then you need to find the area of the unshaded circle in the middle using the same formula but replacing the 10 with a 5

which equals

78.54

We then subtract the 78.54 from the 314.16 and we get 235.62 which is the area of the shaded circle to the right

Answer:

C. y=3/4x-3

Slope: 3/4

y-intercept: -3

Equation: y=3/4x-3

Make a table with x and y just like the one shown below

X:Y

0:-3

4:0

As you can see when x is 0 y equals (-3)

That (-3) is your y-intercept

Now we're going to save that for later

Then you do 0-(-3) and 4-0

You should get positive numbers of 3 and 4

Now you do y/x and that will be 3/4

That 3/4 is your slope

We're going to bring back that (-3) we got earlier and make the equation

The equation is y=3/4x-3

Make sure that you check your work as well

I hope you understand what I'm saying here :)

Answer:

5

Step-by-step explanation:

(12x + 19) + (22x - 9) = 34x + 10

since both are supplementary angles, 34x + 10 = 180

simples algebra leads us to x = 5

Answer:

Step-by-step explanation:

We find an equation using variable [tex]N[/tex] assuming [tex]N[/tex] is in the bottom right corner.

Our equation is [tex]90+60+N=180[/tex] because the sum of the three angles is [tex]180[/tex].

Solving by subtracting both [tex]90+60[/tex] from both sides,

We have [tex]N=30[/tex] which is our solution.
