Step-by-step explanation:

all i know is its 11 degrees warmer

Answer:

-11 degrees Fahrenheit.

Step-by-step explanation:

Equation: -18 + 7 = D

Variable: D meaning the temperature in Darrow Alaska.

Solve: So, it's -11 degrees in Barrow.

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

The constant of proportionality is 2.19

Step-by-step explanation:

$6.57 ÷ 3 = $2.19

Answer: 2.19

Step-by-step explanation: the equation to solve this is y/x= cost per pound (6.57/3=c)

6.57 divided by 3 = 2.19 per pound

Answer:

I don't know what you think you should

Answer:

The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Answer:

Step-by-step explanation:

Given poster boards are $0.75 each, you want to know the number purchased for $4.50. Given brushes are $0.95 and jars of paint are $0.99, you want to know the number of each purchased for $7.80.

The total price is the quantity times the price each:

  4.50 = q × 0.75

  q = 4.50/0.75 = 6

Isabella buys 6 poster boards.

Compatible numbers for the costs of brushes and paint are each 1. A compatible number for the total purchase is 8. This tells us Isabella bought 8 items for 7.80. This gives two equations in two unknowns:

  0.95b +0.99p = 7.80

  b + p = 8

Substituting for b, we have ...

  0.95(8 -p) +0.99p = 7.80

  `7.60 +0.04p = 7.80 . . . . . . simplify

  0.04p = 0.20 . . . . . . . . . . . subtract 7.60

  p = 0.20/0.04 = 5

  b = 8 -5 = 3

Isabella buys 3 paint brushes and 5 jars of paint.

Check

0.95(3) +0.99(5) = 2.85 +4.95 = 7.80 . . . . answer checks OK

Additional comment

Note that we do not need to "guess and check" once we know the number of items purchased.

Or, we can "guess" without the business of compatible numbers by realizing the number of jars must be a multiple of 5 if the total purchase is a multiple of 5 cents. That leaves one possibility, since 10 jars is too many, and 0 jars is not enough.

Answer: 10

Step-by-step explanation: The answer is 10 because xy means x times y, and since x = 10 and y = -2, 10 times -2 equals -20. Now you have to divide that by --2 which is just 2. So -20/2 equals -10. -10's absolute value is 10. Thus the answer is 10.

Answer:

d-2x

Step-by-step explanation:

d is the amount of dollars she had, 2x is the amount of money she used to buy ice creams.

We can write an equation to resemble the problem.

We can write "2x" since she bought 2 ice creams and the price of each is unknown.

We can subtract that by "d" to find how much money she has left.

Put everything together.

2x - d

∛42875 = 35

--------------------check

35*35*35=42875

Answer:

The height of this cube-shaped water tank is 35 m.

Step-by-step explanation:

The formula for the volume of a cube of side length s is V = s^3.

Here V = s^3 = 42,875 m^3.

Taking the cube root of both sides, we obtain the side length, s:

s = ∛(42,875 m^3) = 35 m

The height of this cube-shaped water tank is 35 m.

Answer: C

Step-by-step explanation: the rectangle's height is 2 ft and the length is 9 ft so by doing the formula A=bh the area of the rectangle is 18ft squared so that automatically x's out answers B and C.  A gets taken out as the area of the triangle cannot be the area of the rectrangle so that leaves C as the answer.  assuming the the length of the rectangle is 9 and the width is 2.

Answer:

31.5

Step-by-step explanation:

The MEDIAN is the middle value in a data set.

If the data set has an even amount of values, then the MEDIAN is the MEAN of the two middle values.

For this data set, the middle values are 38 and 25.

To find MEAN, add up all the values and divide by the number of values.

38+25=63

63÷2=31.5

The MEDIAN for this data set is 31.5.

Dividing 2/3 profit of selling concert tickets by 1/5 profit from selling band mechandise.

(2/3) / (1/5) = 10/3 = 3 1/3

Hence band members make 3 1/3 or 10/3 times more profit from ticket sales than from band merchandise sales.

This can be elaborate in such a way also.  

Let suppose the total profit is $30.

then the profit from the ticket sale = 2/3 of 30 = $20

and the profit from the band merchandise sales = 1/5 of 30 = $6

Now dividing 20 by 6, which gives 10/3. the same answer that were calculated above.
