Answer:

A

Step-by-step explanation:

1.020 is less than 1.200

Answer:

Step-by-step explanation:

-2/5 and -1/5

Since -1 > -2

So, -2/5 < -1/5

(ii) -5/7 and -3/7

Since -5 < -3

So, -5/7 < -3/7

(iii)

2/9 and -5/11

Note :- That all positive fraction are greater than negative fraction.

So, 2/9 > -5/11

Answer:

5√10, answer C

Step-by-step explanation:

You can use Pythagoras for this.

calculate the distance between the x coordinates (Δx), which is done by taking the biggest number and subtracting the the coordinates from each other. Aka 2 - - 3 = 2 + 3 = 5

Δy = 5 - - 10 = 15

then a^2 + b^2 = c^2 gives

5^2 + 15^2 = 250

c = √250

Then you still have to simplify. This is done by extracting the root out which results in an integer (a whole number), which is in this case 25.

√250 = √25 * √10 = 5√10, so answer C

Answer:

[tex]3(x - 15) = 30 \\ multiply \: in \: between \: brcket \\ 3x - 45 = 30 \\ 3x = 30 + 45\\ 3x = 75 \\ x = \frac{75}{3} = 25 \\ thank \: you[/tex]

Answer:

x is 25

Step-by-step explanation:

3 ( x - 15) = 30

3x - 45 = 30

3x = 30 + 45

3x = 75

x = 25

Answer:

y= -1.5x-7 is the equation of the perpendicular line

Here's why:

when we convert 2x-3y=8 to standard form, we get y= 2/3x-8/3. This means the perpendicular line will have a slope of the negative reciprocal of the original one, so the perpendicular slope is -1.5. When we substitute the points (-2,-4) into the equation y=-1.5x+b, we get a b value of -7. So the perpendicular line equation is y= -1.5x-7. You can't the parallel line equation with the points (-2,-4) as it is part of the line 2x-3y=8.

Answer:

y=2

Step-by-step explanation:

2y + 8y - 20 = 5 (y -2)

Combine like terms

10y -20 = 5(y-2)

Divide by 5

10y/5 -20/5 = 5/5(y-2)

2y -4 = y-2

Subtract y from each side

2y-y -4 =-2

y -4 = -2

Add 2 to each side

y-4+4 =-2+4

y =2

Answer:

[tex]2y + 8y - 20 = 5(y - 2) \\ 10y - 20 = 5y - 10 \\ 5y = 10 \\ y = 2 \\ thank \: you[/tex]

The steps involved in using dimensional analysis for unit conversion is highlighted below :

The question is incomplete, however, from the portion given, we can see that the text is based on using dimensional analysis to convert units of measurement.

We relate our given unit to the desired or expected unit :

From the text:

To convert 3 miles into feets :

The given unit = 3 miles

The expected or desired unit = feets

The relationship between Given and desired unit :

1 mile = 5280 feets

(5280 feets / 1 mile )

With the unit we want or desire placed at the bottom

To convert a given number of miles to feets ;

Multiply the given value by the relation defined :

Hence,

3 miles to feets :

3 miles × (5280 feets / 1 mile)

Miles cancels out

3 × 5280 feets = 15,840 feets

Another example :

Convert ; 10 minutes into seconds :

1 minute = 60 seconds

given unit = minute ; desired unit = seconds

Relationship = (60 seconds / 1 unit)

10 minutes × (60 seconds / 1 minute)

Minute cancels out :

10 × 60 seconds = 600 seconds

Answer:

7. M = (-1.5,7)

8. (8,4)

9. m<QRS=46°

Step-by-step explanation:

7. Use the midpoint formula which is (x1+x2/2 , y1+y2/2)

So (-1-2/2 , 9+5/2)

(-3/2 , 14/2)

So M = (-1.5,7)

8. This is one simple if you understand.

Since (-6,6) is the starting end point and (1,5) is the mid point then (8,4) has to be the other end point. -6 to 1 is +7. 1 to 8 is +7. 6 to 5 is -1. 5 to 4 is -1.

9. 3x-8+2x+6=98

5x-2=98

5x=100

x=20

So plug in x for QRS

2(20)+6

40+6

46

Answer:

At least 52

Step-by-step explanation:

Paul's current average is a 79. It wouldn't be any of the "at most" answers because the question is looking for an average of "at least" 70. And "at least 79" wouldn't be correct because he could get much less than a 79 and still have an overall average of 70. The answer is at least 52. Hope this helps! Good luck.

Step-by-step explanation: First set up a diamond problem. Find what two numbers add to 60 since 3*20 and add to -11. That would be 15 and -4. Then draw a 2x2 box, and put in 3x^2 the -20, 15x and -4x. Then find the factors. Hope that helped! :)

Answer:

(3x+4)(x-5)

Step-by-step explanation:

Answer:

x = - 2

y = 1

z = 3

Step-by-step explanation:

z = 9/3

z = 3

-y + 2 (3) = 5

-y +6=5

6-5 = y

y = 1

4x + 3(1) - 3 = - 8

4x + 3 - 3 = -8

x = -8/4

X= - 2

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The cost difference between the new and refurbished computer is $800.00 - $640.00 = $160.00. This means that you would save $160.00 by buying the refurbished computer instead of the new one.

Let's say you work for "x" hours, then your gross pay will be:

A = 10x dollars

Your FICA deduction will be 7.65% of your gross pay:

0.0765 ( 10x ) = 0.765x dollars

Your federal tax withholding will be 12% of your gross pay:

0.12 ( 10x ) = 1.2x dollars

Your state tax withholding will be 8% of your gross pay:

0.08 ( 10x ) = 0.8x dollars

The total amount of taxes that will be deducted from your paycheck is the sum of these three amounts:

0.765x + 1.2x + 0.8x = 2.765x dollars

So your net pay will be:

10x - 2.765x = 7.235x dollars

On simplifying the equation , we get

Now, we can calculate the number of hours you would need to work to pay for the new computer:

800 = 7.235x

x ≈ 110.5 hours

Hence , the number of hours is x = 111 hours
