Answer:

99.9%

Step-by-step explanation:

1⇒ 1×10^0

99.9 % ⇒ 999*10^-1

1:999*10^-1

10:999

Therefore it is clear that 99.9% is greater

Answer:

the fraction is 3(x + 4)

Step-by-step explanation:

Answer:

First number: 12

Second number: -3

Step-by-step explanation:

First, let's establish some variables:

x= first number

y= second number

Now, let's turn what is told to us into equations:

The first number minus the second number is 15

  x - y = 15

One-third of the sum of the numbers is one quarter of the first number

 1/3 ( x + y ) = 1/4 ( x )

Now, let's use the first equation given to us to find x in terms of y:

x - y = 15     [Add y to both sides]

x = y + 15

Next, we will take the value of x we found and plug it into the second equation:

1/3 ( x + y ) = 1/4 ( x )     [Plug in x]

1/3 ( {y + 15} + y ) = 1/4 ( {y + 15} )     [Combine like terms]

1/3 ( 2y + 15 ) = 1/4 ( {y + 15} )     [Distribute on both sides]

(2/3)y + 5 = (1/4)y + 15/4     [Subtract 15/4 from both sides]

(2/3)y + (5/4) = (1/4)y     [Subtract (2/3)y from both sides]

5/4 = (-5/12)y     [Multiply both sides by -12/5]

-3 = y

Since we have now found the value of y, let's plug it into our first equation to find the value of x:

x - y = 15     [Plug in y]

x - (-3) = 15     [Simplify]

x + 3 = 15     [Subtract 3 from both sides]

x = 12

So, our first number must be 12 while our second number is -3.

Have a GREAT day!!!

Answer:

-12 and 3

Step-by-step explanation:

Let first no. be x

First number - Second number = 15

So, x - 2nd no. = 15

Second number = 15 + x

First number = x

Now, One-third of the sum of numbers is = [tex]\frac{x+(15+x)}{3} = \frac{15+2x}{3}[/tex]

One-quarter of first number = [tex]\frac{x}{4}[/tex]

Now,

[tex]\frac{15+2x}{3} = \frac{x}{4}[/tex]

= 4(15+2x) = 3x

= 60 + 8x = 3x

= 60 = -5x

= -12 = x

Hence, First number = -12

Second number = -12 + 15 = 3

Check:

[tex]\frac{15-24}{3} = \frac{-12}{4}[/tex]

= [tex]\frac{-9}{3} = -3[/tex]

= -3 = -3

Hence, proved!

Hope it helped. Pls mark me the BRAINLIEST!

Answer:

[tex]108\pi[/tex]

Step-by-step explanation:

Since a cone is 1/3 the volume of a cylinder with equivalent dimensions, we can answer this question by multiplying the given cone volume by 3.

[tex]36\pi \cdot 3 = 108\pi[/tex]

Answer:

Step-by-step explanation:

23 meters

Answer:

Your answer will be 72.

Step-by-step explanation:

You add the two numbers that you are given. This will get you 108. Next you subtract that from 180. 180-108=72

Answer:

The two perpendicular lines on a coordinate grid. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.

Step-by-step explanation:

Answer:

The line which is horizontal on the graph is x-axis and the vertical line that is y-axis

Step-by-step explanation:

Answer:

16 inches

Step-by-step explanation:

We can use the Pythagorean theorem to find the height of the television. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the two smaller sides is equal to the square of the length of the longest side (the hypotenuse). In this case, the diagonal of the television is the hypotenuse and the width and height are the other two sides.

So, we can set up the equation as follows:

a^2 + b^2 = c^2

where a is the width (22 inches), b is the height, and c is the diagonal (27 inches).

We can solve for b:

b^2 = c^2 - a^2

b^2 = 27^2 - 22^2

b^2 = 729 - 484

b^2 = 245

b = √245

b = 15.56 inches (rounded to two decimal places)

So, the height of the television to the nearest inch is 16 inches.

Answer:

13.3

Step-by-step explanation:

Since 8.5 fell in February and 5.1 fell in March. We can add these two numbers together to see what the total is combined normally.

8.5 + 5.1 = 13.6

The record was 26.9, so we'll take this number and subtract it from 13.6 to see how much more fell in one day than the normal

26.9-13.6= 13.3
