Answer:

How much would it cost to buy 10 pounds of peanuts?

Answer: $35

What is the cost per pound?

Answer: $3.50

Step-by-step explanation:

So first, to find the anser to the first question, we need to find out the second question. So, what is the cost per pound.

Well if she got 4 pounds for $14, we should try dividing 14 by 4.

14 divided by 4 = 3.5 ($3.50)

So the cost per pound is $3.50

Now to find out how much it costs if Lulu bought 10 pounds, we need to multiply.

10 x 3.5 = 35

So if she bought 10 pounds, she would play $35

Step-by-step explanation:

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

y ∝ x

y = kx

Where k is a constant and it can be any integer.

If y varies directly with x.

Yes, it is possible to determine by how much y increases or decreases as x increases.

If x increases by 2 then y also increases by 2.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

y varies directly with x.

This can be written as an equation,

y ∝ x

y = kx

Where k is a constant and it can be any integer.

Now,

If x increases by 2.

y = 2k

If k = positive integer

Then y will increase by 2k.

If k = negative integer

Then y will decrease by -2k

So,

Yes, it is possible to determine by how much y increases or decreases.

Thus,

If y varies directly with x.

Yes, it is possible to determine by how much y increases or decreases as x increases.

Answer:

Equal to.

Step-by-step explanation:

The easiest way to figure this out is to convert 14,400 seconds to hours. There are 60 seconds in a minute and 60 minutes in an hour. So, divide 14,400/60, which is 240. This is now 240 minutes. To figure out minutes into hours, divide 240/60, which is 4. 4=4, so 4 hours equals 14,400 seconds.

Yellow paint = 9 liters containers

Blue paint = 12 liters containers

Kimberly’s Paint Supplies sold equal quantities of two paint colors yesterday

What is the smallest amount of each paint color the store must have sold?

Find the Lowest common multiple of 9 liters and 12 liters

9 liters = 18, 27, 36, 45, 54, 63, 72, 81, 90, 99

12 liters = 24, 36, 48, 60, 72, 84, 96, 108

The Lowest common multiple of 9 liters and 12 liters is 36 liters

Therefore, the smallest amount of each paint color the store must have sold to have equal quantities of two paint colors yesterday is 36 liters

opportunity cost

The actions that cannot be taken as a result of an action that is taken are known as the opportunity cost of the actions taken.

" he opportunity cost of a particular activity option is the loss of value or benefit that would be incurred by engaging in that activity, relative to engaging in an alternative activity offering a higher return in value or benefit."

Let say, a homeless man has only $8. He is hungry and don't have cloths to wear. Now, if he buys a burger and some chocolates with all the money he has, then he cannot use that money to buy anything else.  

Therefore, he will not be able to buy any cloth as he spent his money on food. If there is any t-shirt available at the same cost, then the cloth is the opportunity cost.

Therefore, the actions that cannot be taken as a result of an action that is taken are known as the opportunity cost of the actions taken.

The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is [tex]\frac{dy}{dx}[/tex] or:

[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

Example:

Let's say you're give this table:

x: 1, 2

y: 1, 2

Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1

Do the same for x

Now plug the values taken in the slope formula and you get:

[tex]\frac{2 - 1}{2 - 1}[/tex]

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

Therefore the slope is 1.

Answer:

Rise/run

Rise over run.

Step-by-step explanation:

To find the slope pick two perfect spots on the line when the coordinates are not decimals.

Then, take those  two points and figure out the distance. You will use rise/run.

so rise is how much you either go up or down and run is how much you either go right or left. so how much you'll go up or down? how much will you move right or left?

Lets say you have to go up 5 and then left 7 to get to the coordinate.

That's your slope! you went up so it's positive and you went left so it's negative. Rise over run : rise 5 left 7 so, 5 and -7 which is 5/-7 and that's your slope!

Answer:

Option (3) and Option (5)

Step-by-step explanation:

By the property of a triangle,

Sum of interior angles of a triangle is 180°.

m∠Q + m∠R + m∠S = 180°

By substituting the measures of angles in the equation,

(8x - 17)° + (19x + 4)° + (5x + 1)° = 180°

32x - 12 = 180

32x = 192

x = 6

m∠Q = (8x - 17)° = 48 - 17

                          = 31°

m∠R = (19x + 4)° = 114 + 4

                           = 118°

m∠S = (5x + 1) = 30 + 1

                       = 31°

Since, one interior angle measures 118° which is grater than 90°.

Therefore, triangle QRS is an obtuse triangle.

Since, m∠Q = m∠R = 31°

It's an isosceles triangle.

Option (3) and Option (5) are the correct options.

Actually Welcome to the Concept of the Probabilities.

Here, In the game of cards, we have total number of 52 cards in a deck. Since here we have to find the probability of Card 6 from the whole deck.

Let's solve,

Total Number of Cards we have = 52

Total number of 6 numbered Cards in deck = 4

Hence, probability = Favourable Outcomes ÷ Total No. of Outcomes.

So, the Probability of getting a 6 Card = 4/52

= 1/13

Hence the probability is 1/13.

Answer:

the answer is E

Step-by-step explanation:

We want to find how many integers are between 2020 and 2400 such that a criteria is meet, and the criteria is that the four digits are different and are arranged in increasing order.

We will see that there are 15 of these numbers between 2020 and 2400, so the correct option is C.

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

To count the number of digits that meet the given criteria, we first need to analyze how the criteria is.

If the numbers must be in increasing order, then the smallest number that can be in the hundreds place is 3 (the smaller integer larger than 2).

so we have:

23__

The number next to the 3 can be a 4, for example:

234_

And the final number can be any number larger than 4, so we have {5, 6, 7, 8, 9} a total of 5 options.

If instead of a 4, the number next to the 3 is a 5, we have:

235_

And the number next to the five can be any digit larger than 5, so now we have 4 options.

Now, we can't have another number than a 3 in the hundreds place, because if we put a 4 there, we are out of the range, and 3 is the smallest digit that we can use there.

Then we already saw all the possible numbers that we can make, adding the numbers of options that we got above we will get:

5 + 4 + 3 + 2 + 1 = 15

This means that are 15 of these numbers between 2020 and 2400. Then the correct option is C.
