Five percent is the same as 1:20?

Answer:

Not to sure if this is correct but I think it is 6: 1 : 18

pls msg me if you need explanation

Answer:

15

Step-by-step explanation:

Substitute in the values

2 X 3 = 6

21 - 6 =15

To find the value of 21 - 2a when a = 3, substitute 3 for a and simplify to get 21 - 6, which equals 15.

The student has asked to find the value of the expression 21 - 2a given that a = 3. To solve for the expression, substitute the value of a into the expression:

21 - 2(3) = 21 - 6 = 15.

Therefore, the value of the expression when a is 3 is 15.

Answer:

The answer is (11 hours)

Step-by-step explanation:

I first divided 299 by 13 hours to find the rate.

I got the dividend of 23.

All you do now is add $23 per hour.

Once you add 11 hours of this rate. You'll get the sum of $253.

Solving for the amount of hours by cross multiplication

money/hours=money/hours

$299/13hours=$253/x hours

[tex]\frac{299}{13} =\frac{253}{x} \\\\23=\frac{253}{x} \\\\23x=253\\\\x=253/23\\\\x=11[/tex]

Answer:

No and yes.

Step-by-step explanation:

Turn both to percentages. Move the decimal point over two spots to the right, making 2%. Multiply the fraction by 2 to get 2/100. PerCENT. A dollar is 100 cents. The fraction as a percentage is 2%. They are equal.

Yes, 0.02 is greater than [tex]\( \frac{1}{50} \)[/tex].

Explanation:

0.02 can be represented as [tex]\( \frac{2}{100} \)[/tex], which simplifies to [tex]\( \frac{1}{50} \)[/tex].

Since [tex]\( \frac{2}{100} \)[/tex] is greater than [tex]\( \frac{1}{50} \)[/tex], it follows that 0.02 is greater than [tex]\( \frac{1}{50} \)[/tex].

Step-by-step explanation:

1. Convert 0.02 to a fraction: [tex]\( 0.02 = \frac{2}{100} \)[/tex].

2. Compare [tex]\( \frac{2}{100} \)[/tex] with [tex]\( \frac{1}{50} \)[/tex].

3. Simplify [tex]\( \frac{2}{100} \) to \( \frac{1}{50} \)[/tex].

4. Since [tex]\( \frac{1}{50} \)[/tex] is smaller than [tex]\( \frac{1}{50} \)[/tex], we conclude that 0.02 is greater than [tex]\( \frac{1}{50} \)[/tex].

The area of new circle is 5625π square inches.

Step-by-step explanation:

Given,

Area of circular plate = 625π square inches

Let,

Radius = r

Area of circular plate = πr²

[tex]\pi r^2=625\pi[/tex]

Dividing both sides by π

[tex]\frac{\pi r^2}{\pi}=\frac{625\pi}{\pi}\\\\r^2=625[/tex]

Taking square root on both sides

[tex]\sqrt{r^2}=\sqrt{625}\\r=25[/tex]

The radius of plate is 25 inches.

When the radius is tripled = 25*3 = 75 inches

New area of circle = πr²

New area of circle = [tex]\pi (75)^2\\[/tex]

New area of circle = [tex]5625\pi[/tex] square inches

The area of new circle is 5625π square inches.

Answer:

[tex]x=\frac{-17n-r}{(n-34)}[/tex]

Step-by-step explanation:

 Given:                      

                          [tex]n(17+x)=34x-r[/tex]

                Taking the terms of x to one side.

                                [tex]17n+nx=34x-r\\[/tex]

                              [tex]nx-34x=-17n-r\\\\x(n-34)=-17n-r\\\\x=\frac{-17n-r}{(n-34)}[/tex]

The value of x is:

                                 [tex]x=\frac{-17n-r}{(n-34)}[/tex]

x=50 and y=10

because of vertical angles: 3y=x-20

and we also have 3y+5x-100=180 , if we simplify we get 3y=280-5x

we can combine the two equations and get x-20=280-5x and when we solve we get x=50 degrees

then we can plug that into the first equation and get 3y=30, and y=10 degrees

Answer:

x = 50°

y = 10°

Step-by-step explanation:

The vertical angles theorem states that angles across from each other must be equal.

This means that:

3y = x - 20°    or    x = 3y + 20°

5x - 100° = y + 140°

Start with the second equation

5x - 100° = y + 140°

Add 100° to both sides of the equation

5x = y + 240°

Now, substitute the value of x found at the beginning into this equation

5(3y + 20°) = y + 240°

Multiply

15y + 100° = y + 240°

Subtract 100° from both sides of the equation

15y = y + 140°

Subtract y from both sides of the equation

14y = 140°

y = 10°

x = 3y + 20 = 3(10) + 20 = 30 + 20 = 50°

Hope this helps :)

of course the answer is Y=. - 2/3

Answer:

-2/3

Step-by-step explanation:

5 − (y−3)=14− 4 (y+2)

Expand

5 - y + 3 = 14 - 4y - 8

Collect like terms

-y + 4y = 14 - 8 - 5 -3

(-1 + 4)y = - 2

3y = -2

Divide both sides by 3

3y/3 = -2/3

y = -2/3

we know that

The perimeter of a triangle is the sum of the length of their three  sides

so

[tex]P=a+b+c[/tex]

where

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

In this problem we have

[tex]P=(16x-6)\ units\\a=(2x-5)\ units\\b=(5x+4)\ units[/tex]

substitute and solve for the missing length

[tex](16x-6)=(2x-5)+(5x+4)+c\\c=(16x-6)-(2x-5)-(5x+4)\\c=(9x-5)\ units[/tex]

Answer:

2) The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2.

Step-by-step explanation:

Look at the photo below for the graph.

:)

Answer:

Step-by-step explanation:

a. 5 x (c) = -35

Divide each side by 5, which is equal to -6. Remember, two negatives make a positive and one negative and one positive makes a negative.

c. 16/(x) = -4

What times what is equal to a positive 16? To solve, multiply x on both sides of the equation to get 16 = -4x then divide -4 on both sides. You'll get the answer -4. 16/-4 = -4.

e. x/(-3)= -9

Like c, multiply both sides by the denominator, so -3. You'll get x by itself for an equation like x = -9 x -3. Then multiply, remember two negatives equal a positive, so x = 27. 27/-3 = -9.

g. -5000 x y = -10,000

Divide -5000 on both sides to get the equation y = -10,000/-5000. Then solve. y= 2. -5000 x 2 = -10,000.

i. 243/x = -81

Mutiply both sides of the equation by x, so x cancels out. You'll end up getting the equation 243= -81x. Then divide both sides of the equation by -81. Now that we have 1 positive and 1 negative we know our answer has to be negative. The equation should look like 243/-81 = x, which is equal to x=-3. Thus, the answer is 243/(-3)= -81.

k. -92 x y= 184

Divide both sides by -92 to get x by itself. Then you'll get the equation y= 184/-92. y= -2 so, -92 x -2 = 184.

The final discounted price is $18.6

Step-by-step explanation:

In this problem we have to decrease the value of $20 by 7%.

First of all, we have to calculate the 7% of $20. We can do it as follows:

[tex]d=\frac{7}{100}\cdot 20 = 1.4[/tex]

This means that the 7% of $20 is 1.4$.

Now we want to decrease the original value by 7%, so we calculate the difference:

[tex]f=20 - d = 20-1.4=18.6[/tex]

So, the final discounted price is $18.6

The true statement about (f + g)(2) is (D). 343 burned exercise and diet 2 hours.

The functions are given as:

f(x) = 2x+ 210

g(x) =2x + 125

Start by calculating (f + g)(x) using:

(f + g)(x) = f(x) + g(x)

So, we have:

[tex](f + g)(x) = 2x + 210 + 2x + 125[/tex]

This gives

[tex](f + g)(x) = 4x + 335[/tex]

[tex](f + g)(x) = 343[/tex]

In order to find the amount of air to fill a basketball with a diameter of 12 inches, convert the diameter to a radius and then to metric units. Then, use the formula for the volume of a sphere (4/3 * π * r³) to calculate the volume.

This is a problem relating to the volume of a sphere, based in Physics. Given the diameter of the ball (12 inches), we first convert this measure to the radius, which would be half of the diameter (6 inches). This can also be converted to the metric system for ease of calculation, where 1 inch equals roughly 2.54 cm, leading to 6 inches as approximately 15.24 cm.

To find the air required to fill up the ball, we apply the formula for the volume of a sphere (4/3)πr³. Plugging in the value of the radius we get, V = (4/3) * π * (15.24 cm)³. Solving this will get us the volume of air required to fill up the basketball.
