Answer:

t = [tex]\sqrt{63} \\[/tex] or 7.94

Step-by-step explanation:

Yes, you have to use the Pythagorean theorem

A^2+B^2=C^2

So, A=9, B=t, C=12

9^2+t^2=12^2

81+t^2=144

-81        -81

t^2 = 63

t = [tex]\sqrt{63} \\[/tex]

One possible amount the could have paid for furniture is $340,500.

Since the Lopez family pay a price of $345,800 for their new home, and also pay an amount for the furniture in which the digit 5 is exactly 10 times less than it is in the amount they paid for the house.

Since they paid $345,800 for their home and the digit 5 in this amount is in the thousands place, that is 5000.

In the amount paid for the furniture, the digit 5 is exactly 10 times less than in the amount paid for their home.

So, the place of the digit 5 in the amount paid for the furniture is thus 5000 ÷ 10 = 500.

So, the digit 5 is in the hundreds place.

With that in mind, replacing the 8 in the hunderds place in $345,800, one possible amount the could have paid for furniture is $340,500.

So, one possible amount the could have paid for furniture is $340,500.

The survey is an illustration of expected value

132 people in the survey were in the 21 - 30 year old group

From the complete question, 22% of people are in the 21 - 30 year old group

Given that 600 people were surveyed.

The number of people in the 21 - 30 year old group would be:

n = 22% * 600

This gives

n = 132

Hence, 132 people in the survey were in the 21 - 30 year old group

x -intercept is 4

y -intercept is -2

Step-by-step explanation:

SOLUTION:

(x -intercept)

-4x+8y= -16

-4x+8×0= -16

-4x+0= -16

-4x/-4 = -16/-4 (divide both sides by -4)

x=4

(y -intercept)

-4x+8y= -16

-4×0+8y= -16

0+8y= -16

8y/8 = -16/8 (divide both sides by 8)

y= -2

The inverse of the matrix will be [tex]\left[\begin{array}{cc}\dfrac{9}{7}&\dfrac{2}{7}\\\dfrac{10}{7}&\dfrac{3}{7}\\\end{array}\right][/tex]. The correct option is A.

A matrix is a rectangular array or table of numbers, symbols, or expressions that are arranged in rows and columns to represent a mathematical object or a property of such an object in mathematics. For instance, consider a matrix with two rows and three columns.

Given that the matrix is [tex]\left[\begin{array}{cc}3&-2\\-10&9\\\end{array}\right][/tex]. The inverse of the matrix can be solved as below,

[tex]A^{-1} = \dfrac{1}{ad-bc}\left[\begin{array}{cc}d&-b\\-c&a\\\end{array}\right][/tex]

[tex]A^{-1} = \dfrac{1}{3\times9-20}\left[\begin{array}{cc}9&2\\10&3\\\end{array}\right][/tex]

[tex]A^{-1} = \dfrac{1}{7}\left[\begin{array}{cc}9&2\\10&3\\\end{array}\right][/tex]

Answer:

3.4h-2.7d-16

Step-by-step explanation:

Before we even start, we can already simplify some things

For example, in this equation it says +(-7.7d)

We can simplify this to 6h-7.7d-16+5d-2.6h

Now we have to get all of the common variables together

So the d’s and h’s have to be combined together in this equation

This makes a new equation of 3.4h-2.7d-16

That is our answer!

Answer:

26.3

Step-by-step explanation:

Answer:

B, D, and F

They match the graph

John now has X - 3

and splits the remainder equally between himself and his brothers

Each of the brothers now has (X-3)/3 apples (we have to assume here that Jack and Jim didn't have any apples to begin with).

Jack and John both eat half of the apples they have been given

They now have (X-3)/3/2, or just (X-3)/6

Together the three brothers have 4 apples left

Now we say 4 = (X-3)/3 (Jim) + (X-3)/6 (Jack) + (X-3)/6 (John)

From here it's algebra. A nice trick we can do here is to add (X-3)/6 + (X-3)/6 together first, since they have the same denominator:

4 = (X-3)/3 + (X-3)/3

From there we can do the same trick, since now we have two terms that are both something/3:

4 = 2(X-3)/3

Multiply both sides by 3, divide both sides by 2:

6 = X - 3

Add 3 to both sides

9 = X

Answer:

8 or 9

Step-by-step explanation:

John eats 3 gives brothers and himself the remainder they both eat half and both halves are left making it 1 so add up to how much was eaten 3+1=4 and they have 4 left making it 8.  Or just say x-3-1=4 and x=8. It can also be 9 so hopefully, someone else answers because if we add the halves remaining to the altogether it becomes 9 instead. Hope it's right and makes sense.
