Step-by-step explanation:

Brody's model of the Burj Khalifa be 1.7 meters tall to the nearest tenth.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Given:

The Burj Khalifa, a building in Dubai,

United Arab Emirates, is about 828 meters tall.

Brody is making a scale model of this building,

using the scale factor 1:500.

The height of the model = 828 / 500 = 1.656

= 1.7 to the nearest tenth.

Therefore, the model is 1.7 meters tall to the nearest tenth.

Step-by-step explanation:

Answer:

True

Step-by-step explanation:

To check to see if the statement given is true we need to substitute x with 88 and solve.

[tex](1/8)x=11[/tex]

Substitute 'x' for 88.

[tex](1/8)88=11\\\\\boxed{11=11}[/tex]

88 is a solution to the equation, therefore the statement is true.

Answer:

Step-by-step explain

1.5 divide by .25 = 6

The solution to this given system of equations is (x,y) = (0.4,15).

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

y - 13 = 5x

y - 5x = 12

Now,

To do this, we can add both equations together to eliminate x:

(y - 13) + (y - 5x) = 5x + 12 2y - 13 - 5x = 17 2y = 30 y = 15

Now that we have found y, we can substitute it into either equation to find x. For example:

15 - 13 = 5x 2 = 5x x = 0.4

Therefore, by the given system of equations the answer will be (x,y) = (0.4,15).

Answer: positive

Step-by-step explanation:

A negative divided by another negative is always positive. Same rule applies to multiplication. Double negatives equal positives

Given:

The function is

[tex]f(x)=2x^2+kx-9[/tex]

The remainder when f(x) is divided by x+6 is 57.

To find:

The value of k.

Solution:

According to the remainder theorem, if a polynomial function f(x) is divided by (x-a), then f(a) is the remainder.

The remainder when f(x) is divided by x+6 is 57.

Using remainder theorem, we get f(-6)=57.

Putting x=-6 in the given function.

[tex]f(-6)=2(-6)^2+k(-6)-9[/tex]

[tex]57=2(36)-6k-9[/tex]

[tex]57=72-6k-9[/tex]

[tex]57=63-6k[/tex]

On further simplification, we get

[tex]6k=63-57[/tex]

[tex]6k=6[/tex]

[tex]k=\dfrac{6}{6}[/tex]

[tex]k=1[/tex]

Therefore, the value of k is 1.

Answer:

(-1, -5)

Step-by-step explanation:

[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]

1. We must calculate x, for that we must substitute y, so we have:

5x=9x+4

2. Now we solve the equation.

5x-9x=4

-4x=4

x=-1

3. Now we must calculate y

y=5x

y=5(-1)

y=-5

And the answer is (-1, -5)

Answer:

Step-by-step explanation:

Answer:

Yes, the two expressions are equivalent

The given expression 7y - 15 + 2y and   9y - 15 are equivalent.  

Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same, even they look different.

According to the given question.

We have two expressions

[tex]7y - 15 + 2y ...(i)[/tex]

And, [tex]9y - 15 ...(ii)[/tex]

The expression (i) can be written as

[tex]7y - 15 + 2y[/tex]

[tex]=(7y + 2y)-15[/tex]            (adding the like terms)

[tex]= 9y -15[/tex]    

Hence, the given expression 7y - 15 + 2y and   9y - 15 are equivalent.
