Answer:

1st one: 270 ft ^2

2nd: 30 square yards

Step-by-step explanation:

The first one you have to find the area. 15×18= 270

The second one you take the previous answer and divide by 9= 30 square yard. (Might be wrong?)

Answer:

In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher. When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol. For example, 3√(8) means to find the cube root of 8. If there is no superscript number, the radical expression is calling for the square root.

The term underneath the radical symbol is called the radicand.

Explanation:

The value of k determines the slope, or rate of change, of how fast the balloon is climbing per second.

For example, if k = 5, then that means the balloon is going upward at 5 feet per second (equivalent to roughly 3.41 mph)

If k = 5, then y = kt becomes y = 5t. Note how we have the following

and so on. Each time t goes up by 1, d goes up by 5. This is one way to see how the speed is 5/1 = 5 ft per second.

Step-by-step explanation:

Answer:

xy = - 27

Step-by-step explanation:

Note that

(x - y)² = x² - 2xy + y² ← substitute given values, that is

9² = 27 - 2xy

81 = 27 - 2xy ( subtract 27 from both sides )

54 = - 2xy (divide both sides by - 2 )

- 27 = xy

First the 2 bases have surface area pi*1.25^2*2

Then the side

2.5pi*4=10pi

total of 9.817+31.415

=41.232

This approximation could be further round down for this problem to 41.2

Which makes choice C the correct choice.

Step-by-step explanation:

Length of the Circumference

Given a circle of radius r, the length of the circumference, or line surrounding the shape is:

The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:

r=7,917.5/2=3,958.75 miles

Assuming a plane flies around the equator at ground level, the distance it would travel is:

L = 24,873.6 miles

Answer:

x = -2

Step-by-step explanation:

Arrange 6x + y= -5, -6x + 12y=96 vertically:

6x + y= -5

-6x + 12y=96       Now combine like terms:

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

       13y = 91

Solving for y by dividing both sides by 13:  y = 7

Find x by substituting 7 for y in the second equation:  -6x + 12(7) = 96

Then -6x = -84 + 96, or:

-6x = 12, and so x = -2

Answer:

X=35°

Y=70°

Z=110°

I think this ans may help you

Answer and Step-by-step explanation:

We know that the lines are parallel. So,

x is equal to 70° because of vertical angles theorem.

y is equal to 70° because of interior angles theorem.

2z = y

2z = 70

z = 35

z is equal to 35 because of division property of equality.

[tex]22\sqrt{2}[/tex]

Step-by-step explanation:

This is a 45-45-90 triangle and the side lengths are in the ratio [tex]p : p : p\sqrt{2}[/tex]. Given that the hypotenuse is [tex]44[/tex], [tex]p\sqrt{2} = 44[/tex] and [tex]p = 22\sqrt{2}[/tex].

The solution to an equation is the true value of the equation

So, Maria's solution is incorrect

The equation is given as:

[tex]-5n = -9[/tex]

And the solution is given as:

[tex]n = 1[/tex]

To determine if her solution is correct, then she needs to substitute her solution in the given equation.

In other words, substitute 1 for n in [tex]-5n = -9[/tex]

[tex]-5 \times 1 = -9[/tex]

Multiply -5 and 1

[tex]-5 = -9[/tex]

The above equation is false.

This is so, because -5 does not equal -9

i,e, [tex]-5 \ne -9[/tex]

Hence, Maria's solution is incorrect
