Help! Determine if the following number is rational or irrational: -0.1

Step-by-step explanation:

Sum of −8.46 and 5.31 means we need to add −8.46+5.31.

We know that,

|-8.46| > |5.31|

It means we subtract 8.46 - 5.31

At hundredth place, 6-1 = 5

At tenths place, 4-3 = 1

At ones place, 8-5 = 3

It would mean that, 8.46 - 5.31 = 3.15

8.46 has a negative sign. It means that the final answer will have negative sign i.e. −8.46+5.31 = -3.15

Hence, the correct option is (a) " Because |−8.46|>|5.31|, subtract |5.31| from |−8.46| and the sign is negative".

Answer with step-by-step explanation:

The graph passes through both (1,4) and (2,0)

Thus it's slope is the difference of ordinates over difference of abscissae or -4

Thus the equation becomes y = -4x + b

This b is the required b

At x=2 ; y=0

Thus 0= -8 + b

b=8

Answer:

14 minutes

Step-by-step explanation:

In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left over after the call:

15 - 12.76 = 2.24

Then, we divide this number by 0.16:

2.24 / 0.16 = 14

So, Heather's call lasted 14 minutes

Answer:

15 baskets

Step-by-step explanation:

This question is a GCF question

The first step would be to find the factors of 45, 75 and 90

The factors of 45 are: 1, 3, 5, 9, 15, 45

The factors of 75 are: 1, 3, 5, 15, 25, 75

The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

The greatest common factor is 15.

Therefore, the greatest number of baskets they can make if each basket has the same number of pears, the same number of peaches, and same number of apples, with no fruit leftover is 15 baskets

Answer:

The domain is time (t) and the range is distance (d).

Step-by-step explanation:

I TOOK THE Test

The time (t) is the domain and range is distance (d)

The word domain refers to a set of possible input values, on the other hand range refers to the set of possible output value.

Allow x to be an independent variable in the function y is equal to fx, and y is a reliant variable. A value for x is said to be in the domain of a function f if it successfully allows the production of a numerical result y using another value for x.

A train travels at 75 miles per hour.

An equation can be written that compares the time (t) with the distance

here, time (t) is independent value and distance (d) is dependent value which is dependent on time (t).

The domain is time (t) and the range is distance (d).

Answer:

-2x + y = -3

Step-by-step explanation:

First, distribute the right side:

y+5 = 2x+2

Then, subtract both sides by 2x:

-2x + y + 5 = 2

Lastly, subtract both sides by 5:

-2x + y = -3

The formula for the hypotenuse of a triangle is:

[a squared] plus [b squared] = c squared

a and b represent the two sides of the triangle.

You would have to square 8 and 4, add them, then take the square root of it to find the length of the hypotenuse.

x2-x1           4-9    -5

[tex]f(x) = \frac{10}{9}x + 11 \\ [/tex]

So :

[tex]y = \frac{10}{9}x + 11 \\ [/tex]

Subtract the sides of the equation minus 11

[tex]y - 11 = \frac{10}{9}x \\ [/tex]

Multiply the sides of the equation by 9

[tex]9(y - 11) = 10x[/tex]

[tex]9y - 99 = 10x[/tex]

Divided the sides of the equation by 10

[tex] \frac{9y - 99}{10} = x \\ [/tex]

So :

[tex] {f}^{ - 1}(x) = \frac{9x - 99}{10} \\ [/tex]

Answer:

Step-by-step explanation:

To solve the figure. You need to split the shape up with the lines shown.

Let's solve the top triangle first.

The formula to find the area of a triangle is y = 1/2(b*h)

So the base is 2+2+6 which equals 10. And the height is 4.

So y = 1/2(4*10)

PEMDAS solve parentheses first.

y = 1/2(40)

y = [tex]20cm^{2}[/tex]

Now solve the bottom left one.

y = 1/2(2*2)

y = 1/2(4)

y = [tex]2cm^{2}[/tex]

Now the bottom right triangle.

y = 1/2(6*2)

y = 1/2(12)

y = [tex]6cm^{2}[/tex]

And to solve area of a square is

y = b*h

y = 2*2

y = [tex]4cm^{2}[/tex]

And add all of it up to get

y = [tex]20cm^{2}+2cm^{2} +6cm^{2} +4cm^{2} = 32cm^{2}[/tex]

Area = [tex]32cm^{2}[/tex]

Answer:

Number of hamburgers bought = 4

Number of hotdogs bought = 9

Step-by-step explanation:

Let

Number of hamburgers bought = n

Number of hotdogs bought = n + 5

Hamburgers cost = $6.25

Hotdogs cost = $3.75

Total cost = $58.75

6.25n + 3.75(n + 5) = 58.75

Open parenthesis

6.25n + 3.75n + 18.75 = 58.75

Collect like terms

6.25n + 3.75n = 58.75 - 18.75

10n = 40

Divide both sides by 10

n = 40 / 10

= 4

n = 4

Number of hamburgers bought = n = 4

Number of hotdogs bought = n + 5

= 4 + 5

= 9

Answer:

Step-by-step explanation:

I have some sympathy for the way the questions have been set up and numbered.

The givens are that the two lines that look like they are perpendicular, are perpendicular.

<JKP = 67                    Given

<PKL = 180 - 67          < PKL is supplementary to <JKP

<PKL = 113

<PKM = 113 - 90 = 23

Here's what you want to know. <NKO = PKM because they are vertically opposite angles.

Therefore NKO = 23 degrees.

JL is perpendicular to MN, then

m ∠NKO= 23°

Given :

JL is perpendicular to MN and the m∠JKP= 67°

we need to find out m∠NKO

we know that JL is perpendicular to MN.  so, <JKN makes an right angle .

m ∠JKN = 90°

PO is a straight line . It makes an angle 180 degree

m ∠JKP +m ∠JKN +m ∠NKO =180

[tex]67+90+m<NKO=180\\m<NKO=180-90-67\\m<NKO=23[/tex]

m ∠NKO= 23°

Answer:

y = -x - 4

Step-by-step explanation:

Looking at this graph straight off the bat we see the line is going downwards from left to right which is an indication of a negative slope. The slope is 1 considering the line's rise/run (2 units/2 units down on the graph). Thus, we know our slope is 2/2 = 1. Thus, our slope would appear as -(1)x or -x in the equation.

Next, we need to identify where the line crosses the y-axis to identify our y-axis point. Tracing the line, we see that it comes into contact with the vertical y-axis at -4 (4 units South on the y-axis).

Putting these both together we see the equation of the line is y = -x - 4.

Given :

Marcus is a recent college graduate. He has $18,000 in student loans. He took out a loan to buy a car and owes $16,000. The car is now worth $14,000. He got his first paycheck and has $1400 in his checking account.

To Find :

Marcus's net worth.

Solution :

We know, net worth is given by :

Net worth = $( Total amount owns - Total loan )

Net worth = $( 16000+1400) - ( 18000+14000)

Net worth = $(17400 - 32000)

Net worth = $-14600

Therefore, Marcus' net worth is $-14600 ( He is in a loan of $14600).

Hence, this is the required solution.

Answer:

x = 7 1/3

Step-by-step explanation:

First, add 1/2 and 6

1/2 + 12/2 = 13/2 = 6 1/2

Our equation now:

13/2 over 3 - x - 3 over 2 = 0

Next, divide 13/2 by 3

13/2 divided by 3 = 13/6

Our equation now:

13/6 over 3 - (x - 3) over 2 = 0

Now, find common denominators and simplify

13/6 - ((x - 3) times 3) over 6 = 0

22 - 3x over 6 = 0

Multiply by six on both sides

22 - 3x = 0

Subtract 22 from both sides

-3x = -22

Divide by -1

3x = 22

Divide both sides of the equation by 3

x = 22/3

x = 7 1/3
