Answer:

[tex]k = 5[/tex]

Step-by-step explanation:

Given

The table

Required

Determine the constant of proportionality (k)

Represent the time with T and the amount of water with W

k is calculated as follows;

[tex]k = \frac{W}{T}[/tex]

Pick any corresponding values of W and T

[tex]W = 5 \\T=1[/tex]

So

[tex]k =\frac{5}{1}[/tex]

[tex]k = 5[/tex]

Hence, the constant of proportionality is 5

Answer:

15

Step-by-step explanation:

PERT estimate is a measuring strategy that is based on a weighted average. It is used in measuring the uncertainty and risk via three estimates to determine an estimated likelihood for a project's cost or period of completion.

The formula is (O + 4M + P) ÷ 6

Where P is the most pessimistic = 29

M is the most likely = 12

O is the most optimistic = 10

Hence we have (10 + [4*12]+ 29) ÷ 6

= (10 + 48 + 29) ÷ 6

= 87÷6 = 14.5 ≈ 15

Rounded figure is equal to 15.

Hence the final answer to the question is 15

Answer:

-43

Step-by-step explanation:

(-5+7*1)-9*5  ---> * is muliplication sign

(-5+7)-45 --->multiplications first

(2)-45---> next the parantheses

-43 ---> the answer!!!

Answer:   -43

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

Explanation:

We'll use PEMDAS here.

Focus on the stuff in the parenthesis first. We multiply 7 and 1 to get 7*1 = 7

Then we add on -5 getting -5+7 = 2

The stuff in the parenthesis turns into 2

We go from this

(-5+7*1) - 9*5

to this

2 - 9*5

From here we multiply 9 and 5 to get 45, then subtract like so

2-45 = -43

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

So here's the step by step picture

(-5 + 7*1) - 9*5

(-5 + 7) - 9*5

(2) - 9*5

2 - 9*5

2 - 45

-43

Answer:  y = 28x + 15

Step-by-step explanation:

This relationship is linear and so will be of the form;

y = Mx + c

y is the total cost paid

x is the number of days

Assume the points on the line are;

(3, 99) and (6, 183)

Finding M;

= (Y₂ - Y₁) / (X₂ - X₁)

= (183 - 99) / (6 - 3)

= 28

Find c using one of the points and m;

y =Mx + c

99 = 28 * 3 + c

c = 99 - 84

c = 15

Relationship is;

y = 28x + 15

Answer:

2) josh can invite 14 friends. Each will get 3 granola bars and 4 fruit drinks

3) 4(7+3)

Step-by-step explanation:

42 = 3x2x7

56=2x2x2x7

common = 2x7 or 14

42/14 is 3

56/14 is 4

josh can invite 14 friends. Each will get 3 granola bars and 4 fruit drinks

28 = 2x2x7

12=2x2x3

common = 2x2=4

4(7+3)

Answer:

[tex]5^{-3}[/tex]

Step-by-step explanation:

Given the indicial expression

[tex](5^{-2})(5^{-1})[/tex]

First let us convert them to fraction;

5^-2 = 1/5^2

5^-2 = 1/25

Also;

5^-1 = 1/5^1

5^-2 = 1/5

Multiplying both fractions;

[tex](5^{-2})(5^{-1})[/tex] = 1/25 * 1/5

[tex](5^{-2})(5^{-1})[/tex] = 1/125

[tex](5^{-2})(5^{-1})[/tex] = 1/5^3

1/5^3 = [tex]5^{-3}[/tex]

Hence the required answer is [tex]5^{-3}[/tex]

Answer:

1.78 lb

Step-by-step explanation:

Total meat needed = 10 lb

David picks out 3 packages at the supermarket.

Each package weighs

2.73 lb

3.2 lb

2.29 lb

Total weight of the 3 packages = 2.73 lb + 3.2 lb + 2.29 lb

= 8.22 lb

How much more meat does David need?

Amount of meat David needs more = Total meat needed - Total weight of meat picked at the supermarket

= 10 lb - 8.22 lb

= 1.78 lb

David needs 1.78 lb more of meat to complete the total 10 lb meat needed

Answer: 2

Step-by-step explanation:

    −y + 25 = 12y − 1

Переместите все члены, содержащие y, в левую часть уравнения

Вычтем 12y из обеих частей уравнения.

    −y + 25 − 12y = −1

 Вычтем 12y из −y.

    −13y + 25 = −1

Переместите все члены, не содержащие y, в правую часть уравнения.

Вычтем 25 из обеих частей уравнения.

    −13y = −1 − 25

Вычтем 25 из −1.

    −13y = −26

Разделите каждый член на −13 и упростите.

Разделите каждый член в −13y = −26 на −13.

     −13y /-13 = -26/-13

Сократить общий множитель −13.

    −26 /-13

Разделим −26 на −13.

    y = 2

Answer:

C. P and Q

Step-by-step explanation:

The set of ordered pairs that represents a function is a set whereby each x-value has exactly just one corresponding y-value. That is, no x-value would have different y-values paired to it.

For P, each x-value has exactly one y-value paired with it. Therefore, P is a function.

Also, for Q, every x-value has exactly one y-value paired with it. No x-value gives two different y-values. Therefore, Q is also able function.

Thus, both P and Q represents a function.

The values of the angles asked are, x = 44°, y = 136° and z = 136°

A triangle is a polygon with three sides having three vertices, the sum of the interior angles of a triangle is equal to 180°.

Given is a triangle, with two of the angle 82° and 54°

We know that, the sum of the interior angles of a triangle is equal to 180°.

Therefore, x+82°+54° = 180°

x = 180°-136°

x = 44°

Also, we know that, sum of opposite two interior angles of a triangle is equal to exterior angle,

So, y = 82°+54° = 136°

Now, y = z, (vertically opposite angle)

z = 136°

Hence, The values of the angles asked are, x = 44°, y = 136° and z = 136°

Answer:

$170

Step-by-step explanation:

The original price was 100% of the original price since 100% is the entire amount.

The discount on the original price was 30%. That means the discounted price was 100% minus 30% of the original price. That makes the discounted price 70% of the original price.

You are told that the discounted price is $119.

That means that 70% of the original price is $119.

70% as a decimal is 0.7

Let the original price be x.

70% of x is $119

0.7 * x = 119

0.7x = 119

Divide both sides by 0.7

x = 119/0.7

x = 170

Answer: The original price was $170

The amount of money (m) you have left to spend is A) m + 5 ≤ 40.

The answer is A. m + 5 ≤ 40.

The amount of money you have left to spend is represented by m. After buying the shirt, you have m - 5 dollars left. Since you want to have at least some money left, m - 5 ≤ 40.

Option B is incorrect because it states that m + 5 is greater than or equal to 40. This would mean that you have more than 40 dollars left after buying the shirt, which is not possible.

Here is a table that shows the different values of m and m - 5:

As you can see, the value of m - 5 is always less than or equal to 40. This is because m is always less than or equal to 45.

Therefore, the correct answer is A. m + 5 ≤ 40.

Answer:

the answer is 360 M/S

Step-by-step explanation:

Answer:

a = 374

Step-by-step explanation:

Given that:

Cost of children ticket = $6

Cost of adult ticket = $9

Total amount spent = $1219

Total number of people = 16

Let :

Children = c

Adult = a

a + c = 16 - - 1

6c + 9a = 1219 - - - 2

From 1

c = 16 - a

Using 2

6(16 - a) + 9a = 1219

96 - 6a + 9a = 1219

3a = 1123

a = 374.33

Adult = 374.33

The number should be a whole number, maybe there is a problem with the parameters given.
