Answer:

linear function: y = -7x + 150

Step-by-step explanation:

Scott's situation represents a linear function because he is spending $7 each day on lunch. His initial amount in his bank account is $150 and each day he spends the same rate on lunch, $7. So, for any amount of days - represented by 'x' in the equation, you would multiply by -7 (since he is spending) and subtract this amount from his original amount of $150. In this equation, 'y' is equal to his total after 'x' amount of days.

A piggy bank contains 36 coins that consists of dimes and quarters totaling $5.85 how many quarters are in the piggy bank in you

Lesechka [4]

The main idea here is to "translate" the words into maths.
First we need to identify the unknowns and label these.

We need to know the number if dimes and the number of quarters. So lets say
x: number of dimes
y: number of quarters

Now lets write equations from the written problem.
We know that there are 36 coind total, thus:
x + y = 36
We also know that the coins total 5.85 dollars, but it is better to count in cents, that is 585 cents.
x are the number of dimes, their value is x*10
y are quarters with value of y*25
thus:
10x+25y=585

We have two equations and two unknowns now, that needs to be solved to get the answer.

x + y = 36
10x+25y=585

Answer:

108

Step-by-step explanation:

The total of stitches in width is 108, if 9 inches is the total inches in width. The remaining stitches of the remaining width (if this is the case) would be 84 stitches. If we are combining 9 and 2, the total amount of stitches would be 132. If you would like the work, you can ask otherwise hope this helped!

Ross chose a card at random from a deck of 52 cards. Ross replaced the card and then chose a second card. What is the probabilit

DaniilM [7]

Answer:

$\frac{1}{208}$

Step-by-step explanation:

We have been given that Ross chose a card at random from a deck of 52 cards. Ross replaced the card and then chose a second card.

Let us find probability of getting a club.

$\text{ Probability of getting a club}=\frac{13}{52} =\frac{1}{4}$

Now let us find probability of getting the ace of spades.

$\text{ Probability of getting ace of spades}=\frac{1}{52}$

Now let us multiply these to find probability of getting a club and ace of spades.

$\text{ Probability of getting a club and then ace of spades}=\frac{1}{4}*\frac{1}{52}=\frac{1}{208}$

Therefore, probability of getting a club and then the ace of spades $\frac{1}{208}$ .
