A sign language club made $627. 50 from selling popcorn at a festival. The popcorn cost the club $95. 0. Which expression represents the amount of money that was raised for each member of the club? (Let the variable m be the number of members in the club. ) (627. 50 95) (m) (627. 50 minus 95) (m) (627. 50 minus 95) l m (627. 50 95) l m.

Answers

The expression representing the amount of money that was raised for each member of the club is [tex]\dfrac{627.50 - 95.0}{m}[/tex] (in dollars)

How to interpret the division?

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus, [tex]a \div b = a[/tex] divided in b equal parts.

Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]

(it is since [tex]a = a \times 1[/tex] so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )

How to find the profit earned?

Profit earned is the extra money which we make after deducing the cost price of the process we're doing.

So, we get:

Profit earned = Total amount earned - Amount spent initially for preparation to earn

P = Selling price (S.P.) = Cost price (C.P.)

For the given case, we're given that:

Amount made by the sign language club by selling popcorn at a festival = $627.50The cost price for the popcorn to the club = $95.0

The money raised = Amount made by selling popcorn - amount costed to the club for getting popcorn

Money raised = $627.50 - $95.0

If it is given that: m = number of members in the considered club, then:

Money each member of the considered club will get = Money raised divided in equal m parts = [tex]\dfrac{627.50 - 95.0}{m}[/tex] (in dollars)

(we don't write symbols like of currency generally, and understand it from context.)

Thus, the expression representing the amount of money that was raised for each member of the club is [tex]\dfrac{627.50 - 95.0}{m}[/tex] (in dollars)

What is the square root of a number?

The square root is defined as a factor of a number when multiplied by itself, gives the original number.

The given numbers are 0.6 and 1.6. The square roots of given numbers are:

[tex]\sqrt{0.6} = 0.7745[/tex]

[tex]\sqrt{1.6} = 1.2649[/tex]

The first given number 0.6 is less than 1 and its square root is also less than 1. The second given number 1.6 is greater than 1 and its square root is also greater than 1.

Hence we can conclude that the square roots of numbers less than 1 are less than 1 and the square roots of numbers greater than 1 are greater than 1.

Answers

M=0
2/3-4y=8
Y=-11/6
Y=0x-11/6
M=0

Answer:

the slope is 0.

Explanation:

[tex]\hookrightarrow \sf \frac{2}{3} - 4y = 8[/tex]

[tex]\hookrightarrow \sf - 4y = 8- \frac{2}{3}[/tex]

[tex]\hookrightarrow \sf - 4y = \frac{24}{3} - \frac{2}{3}[/tex]

[tex]\hookrightarrow \sf - 4y = \frac{24-2}{3}[/tex]

[tex]\hookrightarrow \sf - 4y = \frac{22}{3}[/tex]

[tex]\hookrightarrow \sf y = \frac{22}{-12}[/tex]

[tex]\hookrightarrow \sf y = -\frac{11}{6}[/tex]

[tex]\hookrightarrow \sf y = -1\frac{5}{6}[/tex]

comparing with the formula: y =  mx + b

                               where m is slope and b is y-intercept.

we found that there is no x. so the value of slope will be 0x. slope = 0

Use the graph. Which system of equations is consistent and dependent?

Answers

Answer:

Option A

Step-by-step explanation:

A system of equations is consistent when it has at least one solution. If the system is represented by lines it's not consistent if the lines that represent it never intercept each other. Now, if a system is consistent and has an infinite number of solutions then we say that is also dependent. When you graph the equations of a consistent and dependent system those graph must all be the same. Let's use this to find the answer. As you can see the graph of option B is composed of two different lines that we can identify so this is not a dependent system. The same happens with C and D, the graph of each of these systems is composed of two lines instead of one. Now let's see if A is dependent. We have the following equations:

y=2x+1

y-1=2x

If the second equation can be rewritten as the first one then they represent the same line and the system is dependent. Let's take the second equation and add 1 to both sides:

y-1+1=2x+1

y=2x+1

Which is exactly the same equation as the first one. Then these two equations represent the same line. Then the answer is option A.

Hence, the correct answer is Option A

Lillian has a bag that contains pineapple chews, cherry chews, and peach chews. She
performs an experiment. Lillian randomly removes a chew from the bag, records the
result, and returns the chew to the bag. Lillian performs the experiment 47 times. The
results are shown below:
A pineapple chew was selected 22 times.
A cherry chew was selected 11 times.
A peach chew was selected 14 times.
Based on these results, express the probability that the next chew Lillian removes
from the bag will be pineapple or peach as a percent to the nearest whole number.

Answers

Answer:

77%

Step-by-step explanation:

since its asking about pineapple and peaches all you have to do is add pineapple and peaches which will give you 36 and since I added all of the numbers together it will give you 36/47

after that you have to put 36/47 in a decimal

36/47 will give you a decimal of .765957 then you got to multiple that by 100 which will give you 76. many numbers all u got to  do is round that up to 77 and that's how u get ur answer

On Derwin farm there is a total of 50 chickens and cows. If there are 118 legs, how
many chickens are there?

Answers

Answer:

Chickens have 2 legs and cows have 4 legs.

Let x = # of chickens and let y = # of cows.

2x + 4y = 118

x + y = 50

x= 50 - y

2(50 - y) + 4y =118

100 - 2y + 4y = 118

2y = 18

y = 9

x = 41
