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

1/2 a cup makes one serving in 1 1/2 a cup there are 3 servings

Step-by-step explanation:

1 . x - 4y = -10

2x + y = -11

multiply the first equation with 2

2x - 8y = -20

-

2x + y = -11

===============

= 0 - 9y = -9

y = 1

x = -6

-------------------------------------------

2.

a - 3b = 24

-

a + 2b = -16

=============

= 0- 5b = 40

b = - 8

a = 0

and so on

Answer: 3 months

Step-by-step explanation:

Answer:

3 1/2 months (Someone please check my math)

Step-by-step explanation:

We can set up this problem by making an equation.

(2900-1200-200-5%)(x)=5000

(1500-5%)(x)=5000

(1425)(x)=5000

5000 divided by 1425 equals 3.50...

My answer would be 3 1/2 months but I could be wrong.

Step-by-step explanation:

Answer:

y = mx + 3

m = Δy/Δx = -3/3 = -1

y = -1x+3

Step-by-step explanation:

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.

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:

Step-by-step explanation:

The exponential model for the given points is y = 6.88(1.47)ˣ

In mathematics, an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.

Given,

points are (8,150) and (9,220)

Exponential function,

y = abˣ            --------(A)

for point (8 , 150)

150 = ab⁸    -------(1)

for point (9 , 220)

220 = ab⁹    -------(2)

Dividing equation (2) by equation (1)

220/150 = ab⁹/ab⁸

Simplifying

1.47 = b

Substituting value of b in equation (1)

150 = a(1.47)⁸

150 = a(21.80)

a = 150/21.80

a = 6.88

Substituting value of a and b in equation(A)

y = 6.88(1.47)ˣ

Hence, y = 6.88(1.47)ˣ is the exponential model for given points.

Step-by-step explanation:

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:

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.
