out of 50 students, 15 are taking English and 30 are taking chemistry. of those students taking English and Chemistry, 6 are in both classes. How many students are taking neither classes?

As in the first four terms, I assume that means using the equation with 1,2,3,4.

11) if n = 1, the answer would be 3.

If n = 2, the answer would be 10.

If n = 3, the answer would be 17.

If n = 4, the answer would be 24.

12) If n = 1, the answer would be 55.

If n = 2, the answer would be 45.

If n = 3, the answer would be 35.

If n = 4, the answer would be 25.

An explicit formula is used to find any term in a sequence by putting in the number of that term in place of the unknown variable.

In order to find the first four terms, we need to plug values, from 1-4, separately in each of the formulas.

For f(n) = 7(n+1) - 11, put values from 1-4 in place of n:

f(1) = 7(1+1) - 11 = 3 ----> First term

f(2) = 7(2+1) - 11 = 10 ----> Second term

f(3) = 7(3+1) - 11 = 17 ----> Third term

f(4) = 7(4+1) - 11 = 24 ----> Fourth term

For f(n) = 65 - 10n, put values from 1-4 in place of n:

f(1) = 65 - 10(1) = 55 ----> First term

f(2) = 65 - 10(2) = 45 ----> Second term

f(3) = 65 - 10(3) = 35 ----> Third term

f(4) = 65 - 10(4) = 25 ----> Fourth term

The answer is 8.

In order to accommodate (or provide space for) all students, with the maximum students per class being 15, there needs to be at least enough for 112. A way to figure this out is 112 / 15 (the total amount of people signed up divided by the amount per class). The quotient is 7.466..., which does not work since you cannot have a 0.466... of a human in a class. This means you must round to the nearest whole number. If there were more students it could accommodate 8 more being that 15 * 8 is 120, but in this case there are only 112.

Answer: 59.5 minutes.

Step-by-step explanation:

1. You have the following information given in the problem above:

- 8 songs are 4.25 minutes long.

- 3 songs are twice as long as each of the others.

2. Therefore, the total time of 8 songs is:

[tex](8)(4.25min)=34min[/tex]

3. And the total time of the 3 songs is:

[tex](2)(3)(4.25min)=25.5min[/tex]

4. Therefore, you have that the result is:

[tex]34min+25.5min=59.5min[/tex]

The concert is 59.5 minutes long.

Let's break down the problem step-by-step:

8 songs x 4.25 minutes = 34 minutes

2 x 4.25 minutes = 8.5 minutes per song

3 songs x 8.5 minutes = 25.5 minutes

34 minutes + 25.5 minutes = 59.5 minutes

So, the total duration of the concert is 59.5 minutes.

Answer:

Sum of 367 and 863 is equal to the sum of 863 and 367. Thus, 367 is the required number.

Step-by-step explanation:

Commutative property of Addition

Let a and b be two real numbers. Then commutative property of addition states that the sum of a and b is equal to the sum of b and a that is

[tex]a + b = b + a[/tex]

Similarly, we a re given here,

[tex]367 + 863 = 1230\\1230 = 863 + 367[/tex]

Thus, sum of 367 and 863 is equal to the sum of 863 and 367.

Thus, 367 is the required number.

Step-by-step explanation:

Answer: The correct option is D.

Explanation:

It is given that in January, Bangkok is hotter than Cape Town while Cape Town is hotter than Moscow.

Since Bangkok is hotter than Cape Town, it means the temperature of Bangkok is more than  or greater than the Cape town.

[tex]\text{Bangkok's temperature}>\text{Cape Town's temperature}[/tex]  .... (1)

Since Cape Town is hotter than Moscow, it means the temperature of Cape town is more than or greater than the Moscow.

[tex]\text{Cape Town's temperature}>\text{Moscow's temperature}[/tex]    ..... (2)

From equation (1) and (2) we get,

[tex]\text{Bangkok's temperature}>\text{Cape Town's temperature}>\text{Moscow's temperature}[/tex]

Therefore, the correct option is D.

The Correct answer is d

Answer:

[tex]44\ gallons[/tex]

Step-by-step explanation:

we know that

A fish tank holds [tex]80[/tex] gallons of water

so

By proportion

Find how many gallons represent [tex]55\%[/tex] of the total tank capacity.

[tex]\frac{80}{100}\frac{gallons}{\%} = \frac{x}{55}\frac{gallons}{\%}\\ \\x=55*80/100\\x= 44\ gallons[/tex]

There are 44 gallons of water in the tank. This is calculated by converting the percentage full into a decimal (0.55) and multiplying it by the total capacity of the tank (80 gallons).

The question is asking how many gallons are currently in the fish tank that is 55% full and has a total capacity of 80 gallons.

First, you need to convert the percentage of the tank that is full (55%) to a decimal. To do this, you divide the percentage by 100.

So, 55 divided by 100 equals 0.55.

Next, you multiply this decimal by the total capacity of the tank to find out how many gallons are currently in the tank. 0.55 times 80 equals 44. Therefore, there are 44 gallons of water in the fish tank now.

2(x - 2) + 3(x + 1) = 9

2x - 4   + 3x + 3  = 9      distributed the 2 and 3 on the left side

Answer: x = 2

We need to find the lowest common multiple of 8 and 12.

Reminder that the LCM is the lowest number that divides evenly with both of the given numbers.

We can make a chart and see that:

Multiples of 8: 8, 16, 24, 32

Multiples of 12: 12, 24...wait! We have a match with 24!

Therefore, there will be 24 more games until both events will occur.

Subtracting whole numbers does not include subtracting negative numbers, whereas when subtracting integers you can include negative numbers.

Answer:When subtracting whole numbers it is like normal addition whereas in subtraction of integers you can include any integers including negative ones

check

for x = 5 → y = 5 + 5 = 10 CORRECT

for x = 10 → y = 10 + 5 =15 CORRECT

for x = 15 → y = 15 + 5 = 20 CORRECT

for x = 20 → y = 20 + 5 = 25 CORRECT

the answer is 504 because 609/58 is 10.5 and then multiply 48 times 10.5 and you get 504

Answer:

There are 504 right handed students in west junior high school.

Step-by-step explanation:

Number of left handed students in east middle school = 58

Number of right handed students in east middle school = 609

Number of left handed students at west junior high = 48

Let the number of right handed students are west junior high be = x

As given, there a a proportional relation between the two, we can denote this as:

[tex]\frac{58}{609}= \frac{48}{x}[/tex]

Now solving for x;

[tex]58x=609*48[/tex]

[tex]58x=29232[/tex]

x = 504

Therefore, there are 504 right handed students in west junior high school.

(7/3)/(9/2)=(14/27)/1

It is a reciprocal. Multiplying is the opposite of Dividing, so if I multiply 3 times 4 I get 12. If i divide 12 by 3 I get 4.

For this one, the best way to do it is write out you formulas, then solve for the first one and see if it works for the second one.

I am going to use h for hamburgers and d for drinks to make it easier.

2h+5d=8

2h+3d=6

So what I did was make the drinks 1, this way you can see if you need to raise it or if the hamburgers could come out even.  When you do that here is what it looks like:

2h+5(1)=8

2h+5=8

2h=3

h=1.50

So here is what you have as of now

h= 1.50 and d= 1

now plug that into the next problem

2h+3d=6

2(1.50)+3(1)=6

3+3=6

So that is your answer

Hamburgers are $1.50

and Drinks are $1

Hope this helps!

Hamburgers cost 1.50 each and its 1.00 for each drink

Answer:

the answer is 10

Step-by-step explanation:

By isolating 'G' in the given equation, 'M = 4G - z', we find that 'G' is equal to '(M + z) / 4', which matches with choice A in the question.

The given equation is M = 4G - z. To solve this equation for G, we should first move 'z' over to the other side of the equation, which will give us M + z = 4G. In the next step, we divide each side of the equation by 4 to isolate 'G'. Our answer is then G = (M + z) / 4. This is equivalent to the choice A. G = M+z/4 given in the original question.

The sum of two numbers is 76. Their difference is 36. Find the numbers

X+y= 76

X-y=36

Add x+x , y cancels out, add76+36

2x= 112

Divide 2 both sides

X= 61

Now substitute your x answer into first original equation

X+y =76

61+y =76

Subtract 61 both sides to get y .

Y= 76-61

Y= 15
