Answer: 28 inches

Step by step explaination:  

First: You do inches over feet- In/Ft

Second: you do 4/60=x/420

Next: You do 60x=1680

                       60     60

Last- Your answer is 28 inches if you divide 1680 and 60.

Answer:

[tex]\huge\boxed{\sf 28\ inches}[/tex]

Step-by-step explanation:

Given that:

Height of the building = 420 feet

According to the scale,

4 inches = 60 feet

×7                ×7         [Multiplying 7 to both sides]

28 inches = 420 feet

So, Height of scale model in inches is 28 inches.

Answer:

The card removed was number '4'.

Step-by-step explanation:

9+8= 17

17+6= 23

23+1=24

You then must divide 24 by 4:

24/4 = 6

Therefore the card removed must have been 4.

Answer:

True! Since if you replace x and y with 2 and 9, you will get 9 = 2 + 7 or 9 = 2 x 2 + 5 which makes the equation true.

Answer:

Step-by-step explanation:

In the question it is given that whether ( 2 , 9 ) is solution of system of equations that are y = x + 7 and y = 2x + 5 .

And we have to tell that it is true or false.

Solution : -

As in the question we're provided with ( 2 , 9 ) . So , Here :

( 1 )

[tex] \longmapsto \qquad \:y = x + 7[/tex]

Substituting value of x and y in equation :

[tex] \longmapsto \qquad \: 9 = 2 + 7[/tex]

[tex] \longmapsto \qquad \: \boxed{\bf{9 = 9}}[/tex]

As we see that left side is equal to right side .

( 2 )

[tex] \longmapsto \qquad \: y = 2x + 5[/tex]

Substituting value of x and y in equation :

[tex] \longmapsto \qquad \: 9 = 2(2) + 5[/tex]

[tex] \longmapsto \qquad \: 9 = 4 + 5[/tex]

[tex] \longmapsto \qquad \: \boxed{ \bf{9 = 9}}[/tex]

As we see that left side is equal to right side .

A self-selecting sample is not likely to be representative. The reason why a self-selecting sample is not likely representative would be discussed below.

A self-selection sample is determined by the individual that are used as data for the research. They are the ones that will determine the inclusion or exclusion of the sample units by either affirming or declining to participate.

The reason self-selecting sample is not likely to be representative is that it is too bias as the individuals that volunteered may not be able to satisfy the goals of the research.

Therefore, a self-selecting sample is not likely to be representative.

Answer:

[tex](\frac{16}{3},- \frac{1}{9} )[/tex] or [tex]x=\frac{16}{3}, y=- \frac{1}{9}[/tex]

Step-by-step explanation:

Hello again!

We are given these two systems:

4x+1=5(x-3y)-6

3(x+6y)+4=9y+19

And we want to solve them for x and y.

First, let's do the distributive property to expand out what is in the parentheses.
4x+1=5(x-3y)-6 --> 4x+1=5x-15y-6

Now simplify 4x+1=5x-15y-6

Subtract 5x from both sides

4x+1=5x-15y-6

-5x   -5x

__________

-x+1=-15y-6

Now add 15y to both sides

-x+1=-15y-6

+15y  +15y

___________

-x+15y+1=-6

Subtract 1 from both sides

-x+15y=-7

Now for 3(x+6y)+4=9y+19:

3x + 18y + 4 = 9y + 19

Subtract 9y from both sides

3x + 9y + 4 = 19

Subtract 4 from both sides

3x + 9y = 15

Here is our system now:

-x+15y=-7

3x+9y=15

On 3x+9y=15, because all of the values are multiples of 3, we can actually divide it by 3.

3x+9y=15

÷3      ÷3

x + 3y = 5

So here it is again:

-x+15y=-7

x+3y=5

These equations can actually be solved using elimination! We will be adding these equations together to clear out a variable, solve for the uncleared variable, and then use the value of the uncleared variable to find the value of the cleared variable

So, add -x+15y=-7 and x+3y=5 together.

-x+15y=-7
+

x+3y=5

_____

18y=-2

Divide both sides by 18

y=[tex]-\frac{1}{9}[/tex]

Now substitute -1/9 as y into either -x+15y=7 or x+3y=5

Taking x+3y=5 for example,

x+3(-1/9)=5

multiply

x-1/3+5

Add 1/3 to both sides

x=5+1/3=16/3

So the answer is [tex]x=\frac{16}{3} , y=-\frac{1}{9}[/tex], or as a point, [tex](\frac{16}{3},- \frac{1}{9} )[/tex]

Answer:Liquid assets

Step-by-step explanation: Can be valued as cash

When paying for higher education, scholarships and grants can be considered liquid assets. Hence, option A is correct.

Liquid assets are assets that can be quickly converted into cash. Although while your assets are valuable possessions that may be traded for cash, not all of them can be sold immediately away for cash or without suffering a loss. A common liquid asset is cash.

Liquid assets include cash on hand, cash stored in a bank, and possessions that can be quickly and readily converted into cash. Common liquid assets include shares, bonds, certificates of deposit, and stocks.

No, an automobile is not considered to be a liquid asset. A car is regarded as a tangible asset that depreciates over time, is more difficult to sell, and is more subject to market swings. It is also challenging to make a quick turn.

Thus, option A is correct.

SSimplifying

2x + -3y = 19

Solving

2x + -3y = 19

Solving for variable 'x'.tep-by-step explanation:

Simplifying

2x + -3y = 19

Solving

2x + -3y = 19

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

2x + -3y + 3y = 19 + 3y

Combine like terms: -3y + 3y = 0

2x + 0 = 19 + 3y

2x = 19 + 3y

Divide each side by '2'.

x = 9.5 + 1.5y

Simplifying

x = 9.5 + 1.5y

Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable. A linear equation can have more than one variable.

Using the t-distribution, it is found that the data does not provide convincing evidence that the mean number is greater when the coupons were addressed to a female.

At the null hypothesis, it is tested if there is no difference, that is, the mean is of 0, hence:

[tex]H_0: \mu = 0[/tex]

At the alternative hypothesis, it is tested if the mean number is greater for females, that is, the mean is greater than 0, hence:
